Vertex Announces European Commission Approval for KALYDECO (ivacaftor) as First and Only CFTR Modulator to Treat Eligible Infants With Cystic Fibrosis as Early as Four Months of Age

- Approval provides opportunity to treat the underlying cause of cystic fibrosis earlier than ever before in Europe -

LONDON 4 November 2020 Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that the EuropeanCommission has granted approval of thelabel extension for KALYDECO (ivacaftor) granules to include the treatment of infants with cystic fibrosis (CF) ages 4 months and older and weighing at least 5 kg who have the R117H mutation or one of the following gating (class III) mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N or S549R.

Our very first CFTR modulator, KALYDECO, was first approved eight years ago, for certain CF patients ages 6 years and older. With todays approval, babies as young as 4 months are eligible and we believe early treatment is important in managing CF, said Reshma Kewalramani, M.D., Chief Executive Officer and President, Vertex. Todays approval is a testament to our commitment to keep going until all people with CF have a treatment option.

The label update is based on data from a cohort in the 24-week Phase 3 open-label safety study (ARRIVAL) consisting of six children with CF ages four months to less than six months who have eligible gating mutations.

KALYDECO (ivacaftor) will be now available to additional eligible patients in Germany and will be available shortly in countries that have entered into innovative long-term reimbursement agreements with Vertex, including the UK, Denmark and the Republic of Ireland. In all other countries, Vertex will work closely with relevant authorities in Europe to secure access for eligible patients.

KALYDECO (ivacaftor) is already approved in Europe for people with CF ages 6 months and older weighing at least 5 kg who have one of the following mutations in the CFTR gene: G551D, G1244E, G1349D, G178R, G551S, R117H, S1251N, S1255P, S549N or S549R.

About Cystic Fibrosis

Cystic Fibrosis (CF) is a rare, life-shortening genetic disease affecting approximately 75,000 people worldwide. CF is a progressive, multi-system disease that affects the lungs, liver, GI tract, sinuses, sweat glands, pancreas and reproductive tract. CF is caused by a defective and/or missing CFTR protein resulting from certain mutations in the CFTR gene. Children must inherit two defective CFTR genes one from each parent to have CF. While there are many different types of CFTR mutations that can cause the disease, the vast majority of all people with CF have at least one F508del mutation. These mutations, which can be determined by a genetic test, or genotyping test, lead to CF by creating non-working and/or too few CFTR proteins at the cell surface. The defective function and/or absence of CFTR protein results in poor flow of salt and water into and out of the cells in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus that can cause chronic lung infections and progressive lung damage in many patients that eventually leads to death. The median age of death is in the early 30s.

About KALYDECO (ivacaftor)

Ivacaftor is the first medicine to treat the underlying cause of CF in people with specific mutations in theCFTRgene. Known as a CFTR potentiator, ivacaftor is an oral medicine designed to keep CFTR proteins at the cell surface open longer to improve the transport of salt and water across the cell membrane, which helps hydrate and clear mucus from the airways.

WIRED Health:Tech 2020: Latest advances and the fight against COVID-19 – Medical News Today

Thursday, November 5th, 2020

WIRED Health:Tech is one of the most prominent annual conferences exploring technological advances in medicine. This year, the main topics included artificial intelligence, remote surgical systems, and the ongoing fight against COVID-19.

This years WIRED Health:Tech conference took place online last month, in an effort to adapt to the challenges posed by the current pandemic.

A range of specialists held presentations about the latest advances in medical technology, including remote surgical systems, e-health, CRISPR technology, and the issue on everyones mind this year: how research can combat the COVID-19 pandemic.

In this Special Feature, we offer an overview of the panels and main takeaways from the presentations.

Stay informed with live updates on the current COVID-19 outbreak and visit our coronavirus hub for more advice on prevention and treatment.

Throughout many of the WIRED Health:Tech presentations, the recurring theme was how technology is helping or hindering the fight against SARS-CoV-2, the coronavirus that has given rise to the current pandemic.

Prof. Heidi Larson from the London School of Hygiene & Tropical Medicine in the United Kingdom spoke of the global response to vaccines, an issue of paramount importance in the context of the pandemic.

Prof. Larson noted that according to her and her colleagues research which appears in The Lancet peoples feelings about vaccines have become far more volatile.

Its a lot more like political opinion polling. They used to be much more stable 1020 years ago. You knew who agreed and who was less confident around vaccines, but thats changing very frequently, she observed.

However, she did offer some positive news:

The overall picture is that [] there is a general trend where people are becoming a little more confident [about vaccines] than they were 5 years ago.

According to Prof. Larson, this may be because public health specialists and communicators are more proactive in dismantling pervasive myths about vaccination over the past few years.

Nevertheless, she cautioned, we do see that Europe remains the lowest in confidence, the most skeptical, with countries like Lithuania [where] only 19% strongly believe that vaccines are safe. The highest [rate] is [in] Finland, at 66% and thats just strongly believe.'

Poland had the most significant drop in confidence in vaccines, she noted.

She also emphasized these fluctuations in confidence in vaccines across the globe occurred before the pandemic. In the current situation, Prof. Larson said, sentiments surrounding vaccinations have become even more volatile.

Because of the hyper-uncertainty and the whole environment of trust and distrust around the COVID vaccine, there are groups that have gotten together to resist even the COVID vaccine, she warned.

The danger of anti-vaccination mentalities can only be mitigated by giving science more of a human face, Prof Larson argued:

We need to bring together the scientific, technological advances that are so valuable, and not lose the human face, but bring that back together [with the scientific perspective]. This isnt just a misinformation problem. This is a relationship problem. This is a cultural revolution, saying we need to change, we need to get back to a more human face in the scientific and medical field.'

Prof. Devi Sridhar a public health advisor and the chair of the Global Public Health department at the University of Edinburgh in the U.K. spoke of the next steps in the fight against the pandemic.

Speaking of the U.K. situation, Prof. Sridhar said that there are certain key actions that the country needs to take to put a stop to the spread of the virus more efficiently:

I think the crucial thing is getting the testing sorted. You need to have a test turnaround time [of] less than 24 hours and have testing widely available. And also [] a strategy: What is the point of a lockdown, what [is] the point of the restrictions?

Other countries have used the lockdown Im thinking of New Zealand, Taiwan, Vietnam, Thailand, Australia [] but theyre using the lockdown to try and eliminate the virus, to get rid of it, and then put in place checks for reimportation, she added.

Prof. Agnes Binagwaho vice chancellor at the University of Global Health Equity in Rwanda went on to speak of the innovations that Rwandan authorities implemented to curb the spread of the new coronavirus in the country.

Prof. Binagwaho said that the first step was to identify both the obstacles and facilitators when it came to stopping the spread of SARS-CoV-2.

According to the expert, having a clear idea of these factors allowed the authorities to establish the best strategy for containing the spread of the virus.

Most importantly, however, according to Prof. Binagwaho, Rwandan authorities made sure to keep its citizens up-to-date with all the daily news regarding the local spread of the virus both good and bad.

[W]hen you need the population to do something to protect itself [] that is not usual, trust counts more than money, she commented.

Some of the technological innovations that the country implemented during the pandemic were robots that take peoples temperatures in airports and hospitals, to limit human contact, and drones that carry supplies to areas that lack appropriate resources.

Prof. Christofer Toumazou from Imperial College London in the U.K. spoke of how technological advances could help during the current pandemic.

Prof. Toumazou, an electronic engineer, created DnaNudge, a fast and accessible DNA testing technology. Its original purpose was helping people understand what health conditions their genetic makeup might predispose them to, so they could make healthier choices.

At WIRED, the researcher and his colleagues said that they adapted this technology to detect COVID-19, creating tests with a turnaround time of only 90 minutes.

In the U.K., the government ordered 5.8 million such tests for state hospitals.

Effectively, it took a pandemic for us to get a technology thats [] prepared for personalized medicine into the hospital system. So the only way that we could bulldoze this was through COVID, Prof. Toumazou noted.

The researcher emphasized just how important this step may be for health, particularly for people with mental health conditions, who would not have to anxiously wait for 48 hours in isolation for their test results.

In a panel discussion, Dr. Indra Joshi director of Artificial Intelligence at NHSx, the U.K. governmental unit responsible for developing national health policies also went on to stress that advanced technology may help not just to better understand the pathology of COVID-19, but also to identify the people who are most at risk.

This, she added, could allow healthcare professionals to provide help faster to those who are likely to be the most affected by infection with the new coronavirus.

In Dr. Joshis view, advances in technology could therefore offer a holistic view of a persons health status and risks, beyond diagnosing COVID-19.

Another panel discussion focused on recent developments in finding a vaccine against the new coronavirus.

The two participants were Tal Zaks, Chief Medical Officer of Moderna Therapeutics, and Prof. Uur ahin, co-founder and CEO of BioNTech.

Both Moderna and BioNTech are testing mRNA candidate vaccines, which use genetic information rather than a viral base to train the immune system against the new coronavirus.

Speaking of the advantages of an mRNA vaccine versus other forms of vaccines, Zaks said that it is better in a number of fundamental ways.

The first is that because we start with genetic information, there is a component of speed that allows you to get into the clinic and then, once youre in the clinic, scale-up manufacturing. Its not by chance that the two leading efforts both leverage mRNA technologies, he pointed out.

I think the second one [] is the biological preciseness so, when you make a recombinant protein, or you otherwise characterize a biologic, the process makes a lot of difference and a lot of things can go wrong. When youre transmitting the [genetic] information, theres no way for the cell to make the wrong bit. So the biological fidelity, if you will, has a higher likelihood to then translate into the kind of immune response you want.

Tal Zaks

I think the last element here is its a very flexible platform, and this takes us a little bit beyond COVID, but the infrastructure required is relatively small and quick, which means, in the manufacturing space, you have tremendous agility that usual technologies dont, Zaks added.

At the time of the WIRED conference, clinical trials for the Moderna and BioNTech candidate vaccines were at similar stages. Since the two approaches have similar premises, the question arises: does this create a sense of competition between the two companies?

According to Zaks, in the context of a pandemic, this is not a valid question. I only have two competitors here: the virus and the clock, he asserted.

He added that should both the Moderna and the BioNTech candidate vaccines demonstrate safety and efficacy, this would be an ideal situation.

The world needs more than one company to succeed here, he said, noting that, if the virus is truly here to stay, as previous research suggests, more than one vaccine may become necessary in the long run.

Prof. ahin agreed:

The way [in which] the whole industry developed vaccines against COVID-19 [] is the best performance of collaboration. Its important to see how people team up for collaboration. Moderna teamed up with the NIH [the National Institutes of Health], we teamed up with Pfizer, AstraZeneca teamed up with Oxford University. So there are several models of collaboration, and we have the strongest transparency in the development of a vaccine.

People see the data almost in real-time coming in, and people understand how [a] phase 1 trial works, how a phase 3 trial works, and Moderna and we even shared our phase 3 protocols so that everyone can see in a transparent fashion how the studies perform and how they are evaluated, Prof. ahin added.

The two researchers also emphasized that this sense of transparency regarding the development of new pharmaceutical products is essential in the long run. They also expressed hope that it may persist after the pandemic subsides.

When asked whether the candidate vaccine development was rushed, so that pharmaceuticals can distribute them sooner rather than later, Prof. ahin explained that the pandemic has caused researchers to find a better, more efficient method of proceeding with clinical trials not a less reliable one.

One important aspect is that instead of skipping [steps] or cutting corners, we decided to do things in parallel. Usually, [in] vaccine development [] you do a phase 1 study, and maybe 6 or 12 months later a phase 2 study, and then decide whether you would do a phase 3 study, he explained.

This is based on minimizing the cost risk, but also based on the traditional way [in which a vaccine] is developed. It is not the best way it is just the traditional way, he also emphasized.

While many of the talks at WIRED Health:Tech revolved around the fight against COVID-19, some also focused on other technological advances in improving patient care.

Dr. Eric Topol founder and director of the Scripps Research TranslationalInstitute talked about using technology to make medicine more humanistic.

The main objective of AI for healthcare and medicine has been to improve accuracy, so that doctors can improve how they diagnose disease and care for their patients, he observed.

This is what is known as precision medicine. But Dr. Topol believes that using AI in medical practice could bring about more far-reaching benefits.

This could include freeing healthcare practitioners from tasks, such as filing information about their patients into digital systems, so that they can pay more attention to their patients.

Medicine has eroded terribly its a rushed job, Dr. Topol asserted in his talk. We see patients in a single-digit number of minutes, and thats not enough.

You need the gift of time, which AI can give back so that people dont feel so rushed and doctors and nurses and clinicians dont feel so rushed either. [] We want to have clinicians and doctors spending more time with patients and less time [at the computer] keyboard.

Dr. Pearse Keane a National Institute for Health Research clinician-scientist at the Institute of Ophthalmology at University College London spoke of how doctors could soon use AI algorithms to diagnose and treat early-stage retinal diseases a set of eye problems that can lead to vision loss.

Dr. Keane made a similar point to Dr. Topols argument, stressing that so many people are affected by eye diseases in the U.K. that specialists are often overwhelmed by the sheer amount of patients waiting for diagnosis and treatment.

Some people are essentially going blind because they cannot be seen and treated early enough, Dr. Keane said. But new technologies and in particular, AI, have at least some role in addressing this problem, he added.

Dr. Keane and colleagues from Moorfields Eye Hospital collaborated with scientists specializing in using the AI technology DeepMind, in demonstrating how to train the system to diagnose retinal diseases correctly and fast-track referrals for specialist treatment.

The researchers published the results of their study in Nature Medicine in 2018. Now, Moorfields Eye Hospital are building a new care and research center, with plans to integrate more advanced technology into this setting.

But Dr. Keane argues that clinical AI help by linking various health data, therefore offering a bigger picture of a persons overall health status and health risks.

Dr. Mark Slack chief medical officer and co-founder of CMR Surgical spoke of the potential of Versius, a surgical robotic system that can help specialists carry out minimally invasive keyhole surgery.

Is keyhole surgery better than open surgery? There are huge advantages for keyhole surgery, Dr. Slack asserted in his presentation.

If you have a large wound [following open surgery], about 50% of those patients will go back to the hospital. If you have a small, minimal-access wound, almost none will go back. If you have a large wound, about a fifth of patients will be required to go back into [the operating] theater if they get a wound infection [] [but] roughly 50% of complications are reduced by having keyhole surgery rather than open [surgery].

Dr. Mark Slack

Finally, Prof. Jennifer Doudna a biochemist at UC Berkeley and founder of the Innovative Genomics Institute, who co-invented CRISPR technology spoke of the revolutionary potential of gene editing. This new technology has taken the medical research world by storm.

Prof. Doudna described gene-editing technology as molecular surgery its a way to alter the DNA in cells and organisms in ways that allow precise correction of disease-causing [genetic] mutations and also allow scientists to do all sorts of other kinds of manipulations of genetic material on living cells and organisms, she explained.

One way in which gene-editing tools might be helpful, she said, might be by helping treat severe blood disorders such as sickle cell disease. Other applications might be in the treatment of eye diseases or even muscular dystrophy.

The scientist explained that, besides CRISPR technologys potential in treating disease, it could also come in handy when detecting viruses, including the new coronavirus.

She even suggested that in the coming months, there may be a CRISPR-based point-of-care diagnostic tool that could help doctors identify infections much faster.

She concluded her talk by noting that:

The potential of this technology continues to advance. I think the keys will be delivery and control of the editing and, of course, ensuring safety, effectiveness, and access. The possibilities are extraordinary its really an exciting time to be working in this field.

Fred Hutch researchers uncover new genetic details of White House COVID-19 outbreak – GeekWire

Thursday, November 5th, 2020

Judge Amy Coney Barrett delivers remarks after President Donald Trump announces her nomination to the U.S. Supreme Court, Sept. 26, 2020, in the Rose Garden of the White House. The event is believed to be responsible for the spread of COVID-19 among some attendees. (Official White House Photo by Andrea Hanks, Public Domain)

Since it was revealed in early October, details about President Trumps COVID-19 infection have been in short supply, including the likely source of his exposure and when he was tested.

New research from the Fred Hutchinson Cancer Research Center in Seattle gives a glimpse into the spread of the disease among Americas first family and White House staff and guests.

Two journalists who directly interacted with White House officials at the end of September but were not in each others company contracted variations of the virus that were highly genetically similar. The genetic code from the SARS-CoV-2, the virus that causes COVID, that infected the journalists contained five unique mutations and were distinct from the genomes of more than 160,000 publicly available virus sequences.

The scientists said this particular lineage of the virus was first documented in the U.S. in April or May, but its exact spread from there was unclear.

Shortly after Trump was infected, Anthony S. Fauci the nations top infectious-disease expert said that the White House had been the site of a so-called super spreader event when it hosted a Rose Garden reception for Judge Amy Coney Barrett, now a member of the U.S. Supreme Court. Photos show that many in attendance did not wear masks. At least 50 COVID-19 cases have been connected to an outbreak associated with the White House, according to the researchers.

Trump Administration officials at the time of the outbreak made little effort to do contact tracing to potentially help contain the spread a decision that drew criticism from some health experts.

When it comes to the source of the White House infections, its sort of an unknowable question, where it entered the environment, said White House deputy press secretary Brian Morgenstern, in a press conference on Oct. 7.

The Fred Hutch-led research calls that assertion into question. While its too late to use the information to limit spread from the initial event, genomic sequencing could provide additional insights into the path of transmission if more samples were tested. It could also help build a more complete picture of the outbreaks spread by analyzing infections that occur weeks or months following the White House event.

Weve seen repeatedly with COVID-19 that the absence of scientific statements provides shelter for speculation and even conspiracy theories to grow. My strategy since January has been to try to address these issues as directly and transparently as I can, said Trevor Bedford, the studys lead.

That includes debunking unfounded theories about COVID spreading in California in the fall of 2019, or being created in a lab.

I still believe that science plays a role in dampening speculation and getting society to a firmer, shared factual footing, Bedford said.

The new investigation was shared Sunday as a pre-print of non peer-reviewed research, posted on medRxiv. The site, pronounced med-archive is a free platform that in recent months has featured up-to-the-minute research during the COVID pandemic.

The studys researchers include scientists from the University of Washington, Seattles Brotman Baty Institute for Precision Medicine, and Howard Hughes Medical Institute in Seattle.

Bedford and his team have done similar lineage analysis for public health departments in Washington, Florida, California, Utah, Minnesota and Michigan, as well as the U.S. Centers for Disease Control and Prevention, the European Centre for Disease Prevention and Control and Public Health England.

A story in the New York Times on Sunday shared the source of the two samples as being Times reporters. One had traveled with the president and other staff on Air Force One on Sept. 26, coming in close proximity with Trump, who was not wearing a mask. On the same day, a second journalist covered the Rose Garden event as well as a news conference the next day, with exposure to unmasked officials who later tested positive.

Both journalists, who wore masks, opted to share their identities, according to the Times.

The researchers ended the study pre-print with a slightly exasperated call to action on the U.S. COVID response.

Science has made a great many discoveries and innovations since [the 1918 influenza pandemic], with genome sequencing being a fairly recent addition to the toolkit to combat infectious disease, they wrote. We, as a society, have the tools to control COVID-19, they just have to be employed.

About LentiGlobin for SCD (bb1111)

SCD is a serious, progressive and debilitating genetic disease caused by a mutation in the -globin gene that leads to the production of abnormal sickle hemoglobin (HbS), causing red blood cells (RBCs) to become sickled and fragile, resulting in chronic hemolytic anemia, vasculopathy and painful vaso-occlusive events (VOEs). For adults and children living with SCD, this means unpredictable episodes of excruciating pain due to vaso-occlusion as well as other acute complicationssuch as acute chest syndrome (ACS), stroke, and infections, which can contribute to early mortality in these patients.

LentiGlobin for SCD (bb1111) is an investigational gene therapy being studied as a potential treatment for SCD. bluebird bios clinical development program for LentiGlobin for SCD includes the ongoing Phase 1/2 HGB-206 study and the ongoing Phase 3 HGB-210 study.

LentiGlobin for SCD was designed to add functional copies of a modified form of the -globin gene ( A-T87Q -globin gene) into a patients own hematopoietic (blood) stem cells (HSCs). Once patients have the A-T87Q -globin gene, their red blood cells can produce anti-sickling hemoglobin (Hb A-T87Q ) that decreases the proportion of HbS, with the goal of reducing sickled red blood cells, hemolysis and other complications.

As of March 3, 2020, a total of 37 patients have been treated with LentiGlobin for SCD to-date in the HGB-205 (n=3) and HGB-206 (n=34) clinical studies. The HGB-206 total includes: Group A (n=7), B (n=2) and C (n=25).

LentiGlobin for SCD received orphan medicinal product designation from the European Commission for the treatment of SCD, and Priority Medicines (PRIME) eligibility by the European Medicines Agency (EMA) in September 2020.

The U.S. Food and Drug Administration (FDA) granted orphan drug designation, fast track designation, regenerative medicine advanced therapy (RMAT) designation and rare pediatric disease designation for LentiGlobin for SCD. LentiGlobin for SCD continues to be evaluated in the ongoing Phase 1/2 HGB-206 and Phase 3 HGB-210 studies.

bluebird bio is conducting a long-term safety and efficacy follow-up study (LTF-303) for people who have participated in bluebird bio-sponsored clinical studies of LentiGlobin for SCD. For more information visit: https://www.bluebirdbio.com/our-science/clinical-trials or clinicaltrials.gov and use identifier NCT02633943 for LTF-303.

LentiGlobin for SCD is investigational and has not been approved in any geography.

About betibeglogene autotemcel

Transfusion dependent beta-thalassemia (TDT) is a severe genetic disease caused by mutations in the -globin gene that result in reduced or significantly reduced hemoglobin (Hb). In order to survive, people with TDT require chronic blood transfusions to maintain adequate Hb levels. These transfusions carry the risk of progressive multi-organ damage due to unavoidable iron overload.

Betibeglogene autotemcel (beti-cel) adds functional copies of a modified form of the -globin gene ( A-T87Q -globin gene) into a patients own hematopoietic (blood) stem cells (HSCs). Once a patient has the A-T87Q -globin gene, they have the potential to produce HbA -T87Q, which is gene therapy-derived adult hemoglobin, at levels that may eliminate or significantly reduce the need for transfusions.

The European Commission granted conditional marketing authorization (CMA) for beti-cel, marketed as ZYNTEGLO gene therapy, for patients 12 years and older with transfusion-dependent -thalassemia (TDT) who do not have a 0 / 0 genotype, for whom hematopoietic stem cell (HSC) transplantation is appropriate, but a human leukocyte antigen (HLA)-matched related HSC donor is not available.

As of March 3, 2020, a total of 60 pediatric, adolescent and adult patients, including 11 patients with at least 5 years of follow-up, across genotypes of TDT have been treated with beti-cel in the Phase 1/2 Northstar (HGB-204) and HGB-205 studies, and the Phase 3 Northstar-2 (HGB-207) and Northstar-3 (HGB-212) studies. In studies of beti-cel, patients were assessed for transfusion independence, defined as no longer needing red blood cell transfusions for at least 12 months while maintaining a weighted average Hb of at least 9 g/dL.

Non-serious adverse events (AEs) observed during clinical studies that were attributed to beti-cel included abdominal pain, thrombocytopenia, leukopenia, neutropenia, hot flush, dyspnoea, pain in extremity, tachycardia and non-cardiac chest pain. One serious adverse event (SAE) of thrombocytopenia was considered possibly related to beti-cel.

Additional AEs observed in clinical studies were consistent with the known side effects of HSC collection and bone marrow ablation with busulfan, including SAEs of veno-occlusive disease. On April 28, 2020, the European Medicines Agency (EMA) renewed the CMA for beti-cel. The CMA for beti-cel is valid in the 27 member states of the EU as well as UK, Iceland, Liechtenstein and Norway. For details, please see the Summary of Product Characteristics (SmPC).

The U.S. FDA granted beti-cel orphan drug designation and Breakthrough Therapy designation for the treatment of TDT. Beti-cel is not approved in the United States. Beti-cel continues to be evaluated in the ongoing Phase 3 Northstar-2 (HGB-207) and Northstar-3 (HGB-212) studies.

bluebird bio is conducting a long-term safety and efficacy follow-up study (LTF-303) for people who have participated in bluebird bio-sponsored clinical studies of beti-cel.

About idecabtagene vicleucel (ide-cel, bb2121)

Ide-cel is a B-cell maturation antigen (BCMA)-directed genetically modified autologous chimeric antigen receptor (CAR) T cell immunotherapy. The ide-cel CAR is comprised of a murine extracellular single-chain variable fragment (scFv) specific for recognizing BCMA, attached to a human CD8 hinge and transmembrane domain fused to the T cell cytoplasmic signaling domains of CD137 4-1BB and CD3- chain, in tandem. Ide-cel recognizes and binds to BCMA on the surface of multiple myeloma cells leading to CAR T cell proliferation, cytokine secretion, and subsequent cytolytic killing of BCMA-expressing cells.

Ide-cel is being developed as part of a Co-Development, Co-Promotion and Profit Share Agreement between Bristol Myers Squibb and bluebird bio. Ide-cel was granted accelerated assessment by the European Medicines Agency (EMA) on March 26, 2020, and the Marketing Authorization Application (MAA) was validated by the EMA on May 20, 2020. The FDA accepted the ide-cel Biologics License Application (BLA) for priority review on September 22, 2020.

KarMMa (NCT03361748) is a pivotal, open-label, single-arm, multicenter, multinational, Phase 2 study evaluating the efficacy and safety of ide-cel in adults with RRMM in North America and Europe. The primary endpoint of the study is overall response rate as assessed by an independent review committee (IRC) according to the International Myeloma Working Group (IMWG) criteria. Complete response rate is a key secondary endpoint. Other secondary endpoints include time to response, duration of response, progression-free survival, overall survival, minimal residual disease evaluated by Next-Generation Sequencing (NGS) assay and safety. The study enrolled 140 patients, of whom 128 received ide-cel across the target dose levels of 150-450 x 10 6 CAR+ T cells after receiving lymphodepleting chemotherapy. All enrolled patients had received at least three prior treatment regimens, including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 antibody, and were refractory to their last regimen, defined as progression during or within 60 days of their last therapy.

CRB-401 (NCT02658929) is an open-label Phase 1 study evaluating the preliminary safety and efficacy of ide-cel in patients with relapsed and refractory multiple myeloma (RRMM). The primary endpoint of the study is safety. CRB-401 was designed as a two-part (dose escalation and dose expansion) study to determine the maximum tolerated dose and further evaluate the safety, tolerability and clinical activity at the recommended Phase 2 dose; these findings established the recommended dose of the Phase 2 KarMMa trial. All patients have been treated in the study and follow-up is ongoing.

In addition to the pivotal KarMMa and CRB-401 trials, bluebird bio and Bristol Myers Squibbs broad clinical development program for ide-cel includes clinical studies (KarMMa-2, KarMMa-3, KarMMa-4) exploring ide-cel combinations and activity in earlier lines of treatment for patients with multiple myeloma, including newly diagnosed multiple myeloma. For more information visit clinicaltrials.gov.

Ide-cel is not approved for any indication in any geography.

About bb21217

bb21217 is an investigational BCMA-targeted CAR T cell therapy that uses the ide-cel CAR molecule and is cultured with the PI3 kinase inhibitor (bb007) to enrich for T cells displaying a memory-like phenotype with the intention to increase the in vivo persistence of CAR T cells. bb21217 is being studied for patients with multiple myeloma in partnership with Bristol Myers Squibb.

bluebird bios clinical development program for bb21217 includes the ongoing Phase 1 CRB-402 study.

Only PARP inhibitor to improve overall survival vs. new hormonal agent treatments in BRCA-mutated metastatic castration-resistant prostate cancer

LONDON, UK I November 5, 2020 I AstraZeneca and MSDs Lynparza (olaparib) has been approved in the European Union (EU) for patients with metastatic castration-resistant prostate cancer (mCRPC) with breast cancer susceptibility gene 1/2 (BRCA1/2) mutations, a subpopulation of homologous recombination repair (HRR) gene mutations.

Prostate cancer is the second-most common type of cancer in men, with an estimated 1.3 million patients diagnosed worldwide in 2018.1 Approximately 12% of men with mCRPC have a BRCA mutation.2

The approval by the European Commission was based on a subgroup analysis of the PROfound Phase III trial which showed Lynparza demonstrated a substantial improvement in radiographic progression-free survival (rPFS) and overall survival (OS) versus enzalutamide or abiraterone in men with BRCA1/2 mutations.

Lynparza is the first and only PARP inhibitor approved in the EU in biomarker-selected advanced prostate cancer. It follows therecommendation for approvalby the Committee for Medicinal Products for Human Use of the European Medicines Agency in September 2020.

Johann de Bono, one of the principal investigators of the PROfound Phase III trial, Head of Drug Development at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust, said: This approval in the EU is a landmark moment that begins a new era of precision medicine in prostate cancer. Lynparza now provides a targeted treatment option at a molecular level to patients with advanced prostate cancer who have historically poor prognosis and few treatment options.

Dave Fredrickson, Executive Vice President, Oncology Business Unit, said: Lynparza more than tripled radiographic progression-free survival and is the only PARP inhibitor to show an overall survival benefit versus certain new hormonal agents for men with BRCA-mutated metastatic castration-resistant prostate cancer. This approval means BRCA testing should now become a critical step in the diagnosis and determination of treatment for men with advanced prostate cancer in the EU.

Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, MSD Research Laboratories, said: The PROfound Phase III trial showed Lynparza provided a clinical benefit for men living with BRCA1/2-mutated metastatic castration-resistant prostate cancer, offering an important option to improve overall survival for these patients in the EU. MSD, along with our collaborator AstraZeneca, looks forward to making this targeted treatment available for patients across the EU as quickly as possible.

The subgroup analysis from the PROfound Phase III trial showed Lynparzareduced the risk of disease progression or death by 78% (based on a hazard ratio [HR] of 0.22, 95% confidence interval [CI], 0.15-0.32; nominal p<0.0001) and improved rPFS to a median of 9.8 months versus 3.0 with enzalutamide or abiraterone in men with mCRPC with BRCA1/2 mutations. Lynparza reduced the risk of death by 37% (based on a HR of 0.63, 95% CI 0.42-0.95) with median OS of 20.1 months versus 14.4 with enzalutamide or abiraterone.

The primary results and overall survival results from the PROfound Phase III trial were published in The New England Journal of Medicine earlier this year.

The full EU approved indication for Lynparza is for the treatment of adult patients with mCRPC and BRCA1/2 mutations (germline and/or somatic) who have progressed following prior therapy that included a new hormonal agent.

Lynparzawas approved in the US for men with HRR gene-mutated mCRPC inMay 2020based on the PROfound Phase III trial. Regulatory reviews are ongoing in other countries around the world.

AstraZeneca and MSD are exploring additional trials in metastatic prostate cancer including the ongoing PROpel Phase III trial testingLynparzaas a 1st-line treatment for patients with mCRPC in combination with abiraterone versus abiraterone alone. Data are anticipated in the second half of 2021.

Metastatic castration-resistant prostate cancer

Prostate cancer is associated with a significant mortality rate.1 Prostate cancer is often driven by male sex hormones called androgens, including testosterone. 3 In patients with mCRPC, prostate cancer grows and spreads to other parts of the body despite the use of androgen-deprivation therapy to block the action of male sex hormones.3 Approximately 10-20% of men with advanced prostate cancer will develop CRPC within five years, and at least 84% of these men will have metastases at the time of CRPC diagnosis. 4 Of men with no metastases at CRPC diagnosis, 33% are likely to develop metastases within two years. 4 Despite advances in treatment for men with mCRPC, five-year survival is low and extending survival remains a key treatment goal.4

BRCA mutations

BRCA1 and BRCA2 are human genes that produce proteins responsible for repairing damaged DNA and play an important role in maintaining the genetic stability of cells. When either of these genes is mutated, or altered, such that its protein product either is not made or does not function correctly, DNA damage may not be repaired properly, and cells become unstable. As a result, cells are more likely to develop additional genetic alterations that can lead to cancer and confer sensitivity to PARP inhibitors includingLynparza.5-8

PROfound

PROfound is a prospective, multicentre, randomised, open-label, Phase III trial testing the efficacy and safety ofLynparzaversus enzalutamide or abiraterone in patients with mCRPC who have progressed on prior treatment with NHA treatments (abiraterone or enzalutamide) and have a qualifying tumour mutation in BRCA1/2, ATM or one of 12 other genes involved in the HRR pathway.

The trial was designed to analyse patients with HRR gene mutations in two cohorts: the primary endpoint was rPFS in those with mutations in BRCA1/2 or ATM genes and then, ifLynparzashowed clinical benefit, a formal analysis was performed of the overall trial population of patients with HRR gene mutations (BRCA1/2, ATM, CDK12 and 11 other HRR gene mutations). AstraZeneca and MSD announcedin August 2019that the trial met its primary endpoint of rPFS.

Lynparza

Lynparza (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumours harbouring a deficiency in HRR, such as mutations in BRCA1 and/or BRCA2. Inhibition of PARP with Lynparza leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. Lynparza is being tested in a range of PARP-dependent tumour types with defects and dependencies in the DDR pathway.

Lynparza is currently approved in a number of countries, including those in the EU, for the maintenance treatment of platinum-sensitive relapsed ovarian cancer. It is approved in the US, the EU, Japan, China, and several other countries as 1st-line maintenance treatment of BRCAm advanced ovarian cancer following response to platinum-based chemotherapy. It is also approved in the US as a 1st-line maintenance treatment with bevacizumab for patients with HRD-positive advanced ovarian cancer (BRCAm and/or genomic instability). Lynparza is approved in the US, Japan, and a number of other countries for germline BRCAm, HER2-negative, metastatic breast cancer, previously treated with chemotherapy; in the EU, this includes locally advanced breast cancer. It is also approved in the US, the EU and several other countries for the treatment of germline BRCAm metastatic pancreatic cancer. Lynparza is approved in the US for HRR gene-mutated mCRPC (BRCAm and other HRR gene mutations). Regulatory reviews are underway in several countries for ovarian, breast, pancreatic and prostate cancers.

Lynparza, which is being jointly developed and commercialised by AstraZeneca and MSD, has been used to treat over 30,000 patients worldwide. Lynparza has the broadest and most advanced clinical trial development programme of any PARP inhibitor, and AstraZeneca and MSD are working together to understand how it may affect multiple PARP-dependent tumours as a monotherapy and in combination across multiple cancer types. Lynparza is the foundation of AstraZenecas industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.

The AstraZeneca and MSD strategic oncology collaboration

In July 2017, AstraZeneca and Merck & Co., Inc., Kenilworth, NJ, US, known as MSD outside the US and Canada, announced a global strategic oncology collaboration to co-develop and co-commercialise Lynparza, the worlds first PARP inhibitor, and Koselugo (selumetinib), a mitogen-activated protein kinase (MEK) inhibitor, for multiple cancer types. Working together, the companies will develop Lynparza and Koselugo in combination with other potential new medicines and as monotherapies. Independently, the companies will develop Lynparza and Koselugo in combination with their respective PD-L1 and PD-1 medicines.

AstraZeneca in oncology

AstraZeneca has a deep-rooted heritage in oncology and offers a quickly growing portfolio ofnew medicines that has the potential to transform patients lives and the Companys future. With seven new medicines launched between 2014 and 2020, and a broad pipelineof small molecules and biologics in development, the Company is committed to advance oncology as a key growth driver for AstraZeneca focused on lung, ovarian, breast and blood cancers.

By harnessing the power of four scientific platforms Immuno-Oncology, Tumour Drivers and Resistance, DNA Damage Response and Antibody Drug Conjugates and by championing the development of personalised combinations, AstraZeneca has the vision to redefine cancer treatment and, one day, eliminate cancer as a cause of death.

Penn Medicine Researchers Receive $5.4 million Grant to Find Genetic Drivers of Testicular Cancer – Newswise

Saturday, October 31st, 2020

Newswise PHILADELPHIAThe international hunt to find more genetic risk markers for testicular cancer is expanding. A team of researchers led by Katherine L. Nathanson, MD, deputy director of the Abramson Cancer Center and the Pearl Basser Professor for BRCA-Related Research in the Perelman School of Medicine at the University of Pennsylvania, was recently awarded $5.4 million over five years from the National Institutes of Health to continue the long-standing genomics work of the TEsticular CAncer Consortium (TECAC).

A total of nearly $7 million has been awarded to TECAC, which includes researchers from 27 institutions around the world, whose collaborative goal is understand the genetic susceptibility to testicular germ cell tumors (TGCT).

TGCT are the most common cancer in the United States and Europe in men between the ages of 15 to 45, and the number of cases has continued to rise over the past 40 years. Approximately 50 percent of the risk of disease is due to genetic factors, higher than for other cancer types.

To date, TECAC has identified 22 novel susceptibility alleles, bringing the total number of risk markers to 66. Nathanson led a study in 2017 published in Nature Genetics that identified eight of those markers in previously unknown gene regions, as well as four in previously identified regions.

Members of TECAC also were the first to identify CHEK2, a moderate penetrance gene for TGCT. Penetrance refers to the proportion of people with a mutation in specific gene. Unlike other solid tumor types (e.g. breast, ovarian), the inherited risk of TGCT is likely due to multiple variants rather than any single gene.

Our work has revealed critical roles for genetic variants and mutations in testicular germ cell tumors and defined the biology of TGCTs as associated with defects in maturation of male germ cells, but theres still much more to discover with this highly heritable disease, Nathanson said. This grant will allow us to continue to pool our resources and expertise to better understand its biology and etiology, as well as provide data that can help identify men at higher risk of the disease and in need of surveillance.

The latest round of funding will focus on three projects: identify rare and common variants using whole exome genetic sequencing from biosamples of more than 2,000 men; conduct a transcriptome-wide association study, or TWAS, to identify novel candidate susceptibility genes in nearly 250,000 men (the largest to date); and further evaluate any variants or gene discovered from those two projects using tools, such as CRISPR, in cells.

Other Penn collaborators on this grant (R01 CA164947 A1) include David Vaughn, Linda Jacobs, Li-San Wang and Mingyao Li.

enGene Receives Funding Through Cystic Fibrosis Foundation’s Path to a Cure for the Discovery of Novel Gene Therapies to Treat Cystic Fibrosis -…

Saturday, October 31st, 2020

BOSTON and MONTRAL, Oct. 29, 2020 /PRNewswire/ -enGeneInc.,abiotechnology company developing non-viral gene therapies for local administration into mucosal tissues enabled by its proprietary DDX platform, announced today an award from the Cystic Fibrosis Foundation for the discovery of genetic medicines to treat patients with cystic fibrosis (CF).

The award was made as a part of the CF Foundation's $500 million Path to a Cure initiative to accelerate the discovery and development of treatments that address the underlying cause of the disease.

Affecting over 75,000 patients worldwide, CF is a genetic disease caused by mutations in a gene known as the cystic fibrosis transmembrane conductance regulator (CFTR) that render a non-functional CFTR protein. Consequently, multiple organs are affected by disease, chief among them the lungs, where chronic infections and a worsening ability to breathe leads to progressive lung damage and premature death. Patients with nonsense and other rare mutations in both copies of the CFTR gene currently have no therapies that treat the underlying cause of the disease.

"Gene therapy holds promise for the treatment of CF by delivering a functional copy of the CFTR gene to the lungs to restore function and alleviate disease. enGene is developing a DDX-based inhalable formulation to carry DNA to the airways with the goal of functional complementation of CFTR mutations. We are thrilled to have the support of the Cystic Fibrosis Foundation to discover novel gene therapy candidates for patients with CF," commented Jose Lora, CSO of enGene.

In developing an inhalable gene therapy for CF, enGene is coupling a non-viral DNA payload to its biocompatible DDX carrier in an effort to create genetic medicines that allow repeatable and titratable dosing to achieve meaningful efficacy.

"Gene therapies have made a remarkable impact in many fields of medicine, but unlocking their full potential in mucosal tissues such as the lung has been elusive, leaving many patients with CF without available treatment options. We are honored to be working with the CF Foundation to accelerate our research and development efforts towards improving and extending the lives of all CF patients," said Jason Hanson, enGene's President and CEO.

About enGene Inc.enGene Inc. is a biotechnology company developing a proprietary non-viral gene therapy platform for localized delivery of nucleic acid payloads to mucosal tissues. The dually derived chitosan (DDX) platform has a high-degree of payload flexibility including DNA and various forms of RNA with broad tissue and disease applications. In addition to developing gene therapies for the lungs, enGene has developed a unique dual-immune activator for patients with non-muscle invasive bladder cancer which has completed IND-enabling studies. The company is evolving its technology to enable applications in multiple mucosal tissues with areas of high unmet medical need.www.engene.com/

New screening tool could turn up genes tied to developmental disorders – STAT

Saturday, October 31st, 2020

Scientists in Vienna have developed a new human tissue screening technique that has identified previously unknown genes involved in causing microcephaly, a rare genetic disorder, and that could one day be used to identify unknown genes tied to other conditions.

In a study published Thursday in Science, researchers screened lab-grown human brain tissues for 172 genes thought to be associated with microcephaly, a condition in which babies are born with smaller-than-normal brains and have severe mental impairments. The search revealed 25 new genes linked to this rare neurological condition, adding to the 27 already known genes tied to microcephaly. The researchers also uncovered the involvement of certain pathways that were previously unknown to be connected to the disease.

This is a proof of concept, said Jrgen Knoblich, a molecular biologist at the Austrian Academy of Sciences Institute of Molecular Biotechnology and co-author of the study. With our ability to query many diseased genes at the same time and ask which ones are relevant in a human tissue, we can now study other diseases and other organs.

For decades scientists have relied on small animals as models to make sense of how a human brain develops. But it turns out that our brains are not blown-up versions of a rodent brain. Mice and rat brain surfaces, for instance, are smooth, unlike the shrivelled walnut look of a human brain, with its countless folds. Also, these rodents are born with a somewhat complete brain, in which most neurons are in place, although they continue to form new connections after birth. In a human child, on the other hand, there are a massive number of neurons that form and populate the cortex after birth.

There are some processes that happen in our brain and not in mice brains that are responsible for human brains becoming so big and powerful, Knoblich said. This generates a very big medical problem, which is how do we study processes that are only happening in humans.

To address this problem, several scientists including Knoblich developed human brain organoids that are no bigger than a lentil, created from stem cells, and function just like a working human brain. With an interest in studying neurodevelopmental disorders like microcephaly, Knoblichs team used these miniature substitute brains to look for clues about the genes that may hamper brain development.

Typically, scientists conduct genetic screening by inactivating select genes one by one to understand their contribution to bodily functions. But screens of human genes are restricted to cells grown in petri dishes in two dimensions, in which cells dont interact very much.

Microcephaly is a tissue disease and we couldnt really study it in 2D, said Christopher Esk, a molecular biologist at the Austrian Academy of Sciences Institute of Molecular Biotechnology and co-lead author of the study.

So, the researchers developed a technique called CRISPR-Lineage Tracing at Cellular resolution in Heterogeneous Tissue, which uses the gene-editing technology to make cuts in DNA and knockout genes in combination with a barcoding technology that tracks parent stems and their progeny cells as the 3D brain organoid develops.

Using an organoid developed from cells of a microcephalus patient, they kept an eye out for mutations that gave rise to fewer cells and thus a small brain in comparison with a healthy one.

The researchers used CRISPR-LICHT to simultaneously screen 172 potential microcephaly causing gene candidates and found 25 to be involved.

Among them was a gene called Immediate Early Response 3 Interacting Protein 1 in the endoplasmic reticulum, which is the protein processing station within a cell. This protein processing is required to properly process other proteins, among them extracellular matrix proteins, which are in turn important for tissue integrity, and thus brain size, Esk said.

Kristen Brennand, a stem cell biologist at the Icahn School of Medicine at Mount Sinai in New York, who wasnt involved in the study, said she appreciated how the research captured this causal link. Clinical genetics can identify mutations in patients, but fall short of identifying causal mutations that definitively underlie disease risk, she said.

Going forward, Knoblich and his colleagues hope to use CRISPR-LICHT to screen many more genes that may be associated with other brain development disorders. Weve done it for microcephaly, and were already doing it for autism, he said. But the method can be applied to any type of organoid or any type of disease and any cell type.

Prowess of Bionano Genomics’ Saphyr System in Uncovering Novel Genetic Variations That Cause Cancer and Genetic Disease in Full Display at ASHG 2020 -…

Saturday, October 31st, 2020

SAN DIEGO, Oct. 27, 2020 (GLOBE NEWSWIRE) -- Bionano Genomics, Inc. (Nasdaq: BNGO) announced that human genetics researchers using the Saphyr system will present their results at the American Society of Human Genetics (ASHG) Annual Meeting, being held virtually at http://www.ashg.org between October 27-30. The impact of structural variation analysis using the Saphyr system will be demonstrated at ASHG with 18 oral and poster presentations which cover an expanding array of diseases like cancer predisposition, microdeletion syndromes, repeat expansion disorders, neurodegenerative diseases, disorders of sex development and a variety of other genetic diseases. Additionally, these presentations show Saphyrs abilities to elucidate the exact structure of complex genomic rearrangements such as large inversions, chromothripsis and low copy repeats.

The scientific importance and quality of the studies utilizing Saphyr and presented at ASHG have increased year over year, said Erik Holmlin, Ph.D., CEO of Bionano. As more scientists present and publish their important discoveries made with Saphyr, an increasing number of potential future Saphyr users become aware of its prowess in uncovering novel genetic variants that contribute to cancer and genetic disease, which could drive more adoption and utilization for basic genetic research and clinical studies alike.

Below is a summary of key presentations to be given at ASHG 2020 featuring the use of Bionanos optical genome mapping technology:

Live Presentation October 29, 2020, 11:45AM-12:00PMDeciphering Genomic InversionsChristopher M. Grochowski, Baylor College of MedicineGenomic inversions are a class of structural variation (SV) relevant in evolution, speciation, and human disease but challenging to detect and resolve using current genomic assays. While short-read WGS can detect a fraction of copy number neutral inversions, those mediated by repeats or accompanied by CNVs remain challenging. The utilization of multiple technologies and visualization of unbroken DNA through long molecule approaches facilitate detection ofin cisevents and resolution of SVs containing two or more breakpoint junctions.

The following Co-Labs, Poster Sessions and Abstracts are available for on-demand viewing during and after ASHG 2020:

Bionano Laboratory Co-Lab Session: Resolving Complex Haplotypes Implicated in Alzheimers and Other Neurodegenerative Diseases.Mark T. W. Ebbert, Neuroscience Department, Mayo ClinicAlzheimers disease is genetically complex with no meaningful therapies or pre-symptomatic disease diagnostics. Most of the genes implicated in Alzheimers disease do not have a known functional mutation, meaning there are no known molecular mechanisms to help understand disease etiology.

In this co-lab session, Mark T. W. Ebbert of the Mayo Clinic will discuss his teams work toward identifying functional structural mutations that drive disease in order to facilitate a meaningful therapy and pre-symptomatic disease diagnostic. Some of the genes and regions implicated in Alzheimers disease are genomically complex and cannot be resolved with short-read sequencing technologies. These regions include MAPT, CR1, and the histocompatibility complex (including the HLA genes).

3342 Bionano Poster Session: High Throughput Analysis of Disease Repeat Expansions and Contractions by Optical MappingErnest Lam, Sr Manager Bioinformatics, Bionano GenomicsRepeat expansions and contractions are associated with degenerative disorders such as facioscapulohumeral muscular dystrophy (FSHD). Southern Blotting is the gold standard for long repeat analysis but has many limitations. Optical genome mapping allows for efficient analysis of diseases associated with repeat expansion and contraction.

2190 Bionano Poster Session: Rapid Automated large Structural Variation Detection in Mouse Genome by Whole Genome SequencingJill Lai, Sr Applications Scientist, Bionano GenomicsIdentifying SVs for key model organisms such as mouse and rat is essential for genome interpretation and disease studies but has been historically difficult due to limitations inherent to available genome technologies. We updated the Saphyr analysis pipeline such that copy number variant (CNV) and SV analyses could now be applied to mouse and other non-human species, and constructed a control SV database for annotating variants, and identified strain-specific SVs/CNVs as well as variation shared among strains.

Beat AML Master Clinical Trial Shows Promise for Precision Medicine in the Treatment of AML – Cancer Network

Saturday, October 31st, 2020

Patients who participated in the Beat AML Master clinical trial were found to have superior outcomes with precision medicine, compared to patients with acute myeloid leukemia (AML) who opted for standard chemotherapy treatment, according to a study published in Nature Medicine.1

Overall, the study demonstrated that a precision medicine therapy strategy in AML is feasible within 7days of sample receipt and before treatment selection, allowing patients and physicians to rapidly incorporate genomic data into treatment decisions without increasing early death or adversely impacting overall survival (OS).

The study shows that delaying treatment up to seven days is feasible and safe, and that patients who opted for the precision medicine approach experienced a lower early death rate and superior overall survival compared to patients who opted for standard of care, corresponding author John C. Byrd, MD, D. Warren Brown Chair of Leukemia Research of The Ohio State University, said in a press release.2 This patient-centric study shows that we can move away from chemotherapy treatment for patients who wont respond or cant withstand the harsh effects of the same chemotherapies weve been using for 40 years and match them with a treatment better suited for their individual case.

In the ongoing Beat AML trial, researchers prospectively enrolled untreated patients with AML who were60 years or older with the aims of providing cytogenetic and mutational data within 7days of the sample receipt and before treatment selection, followed by treatment assignment to a sub-study based on the dominant clone. In total, 487 patients with suspected AML were enrolled in the study and 395 were deemed eligible for analysis.

The median age of the participants was 72 years (range 60-92 years). Overall, 374 patients (94.7%) had genetic and cytogenetic analysis completed within 7days and were centrally assigned to a Beat AML sub-study, while 224 (56.7%) were enrolled on a Beat AML sub-study. The remaining 171 patients elected to receive either standard of care (n = 103), investigational therapy (n = 28), or palliative care (n = 40). Moreover, 9 patients died before treatment assignment.

Demographic, laboratory, and molecular characteristics were not found to be significantly different between patients on the Beat AML sub-studies and those receiving standard of care (induction with cytarabine+daunorubicin [7+3 or equivalent] or hypomethylation agent).

However, 30-day mortality was less frequent, and OS was significantly longer for patients enrolled on the Beat AML sub-studies versus those who elected to receive standard of care. The median OS for patients included in the Beat AML trial was 12.8 months versus 3.9 months for patients opting for standard of care.

To date, the trial has now screened more than 1000 patients at 16 cancer centers. The data presented herein represents patient enrollment during a slice of time between November 17, 2016 and January 30, 2018.

The study is changing significantly the way we look at treating patients with AML, showing that precision medicine, giving the right treatment to the right patient at the right time, can improve short and long-term outcomes for patients with this deadly blood cancer, Louis J. DeGennaro, PhD, president and CEO of the Leukemia & Lymphoma Society (LLS), the conductor of the trial, said in the release. Further, Beat AML has proven to be a viable model for other cancer clinical trials to emulate.

Recently, LLS launched itsBeat COVIDtrial, which leveraged the Beat AML infrastructure to quickly pivot to treat patients with blood cancer who are infected with the coronavirus disease 2019 (COVID-19) virus. The trial is testing the drug acalabrutinib (Calquence), which is currently approved to treat several types of blood cancers. The trial is open to patients diagnosed with all types of blood cancers.

Additionally, LLS is also planning other precision medicine trials modeled after Beat AML, including LLS PedAL, a global precision medicine trial for children with relapsed acute leukemia, currently on track to launch in summer 2021, and Stop MDS, a master trial for patients withmyelodysplastic syndromes.

Alnylam Wins Prestigious Prix Galien Award for Best Biotechnology Product with First-Ever Approved RNAi Therapeutic, ONPATTRO (patisiran) – BioSpace

Saturday, October 31st, 2020

Oct. 30, 2020 11:00 UTC

CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, today announced it has won the 2020 Prix Galien USA Award for Best Biotechnology Product for ONPATTRO (patisiran). The award, which recognizes excellence in scientific innovation that improves the state of human health, was presented by the Galien Foundation during the 50th Annual Prix Galien USA Awards ceremony yesterday.

We are thrilled to receive this prestigious recognition for ONPATTRO and want to share this award with the incredible patients, caregivers, scientists, healthcare professionals, and colleagues that helped us succeed in making RNAi therapeutics, an entirely new class of medicines, a reality for patients, said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. The breakthrough approval of ONPATTRO was a result of nearly two decades of determination to deliver the first-ever FDA-approved treatment to adult patients living with the polyneuropathy of hereditary ATTR (hATTR) amyloidosis. We also want to recognize the continued industry efforts in helping those living with this progressive, debilitating condition.

In 2019, ONPATTRO won the Prix Galien Award for Best Biotechnology Product in Italy and the Netherlands.

About ONPATTRO (patisiran)

ONPATTRO is an RNAi therapeutic that was approved in the United States and Canada for the treatment of the polyneuropathy of hATTR amyloidosis in adults. ONPATTRO is also approved in the European Union, Switzerland and Brazil for the treatment of hATTR amyloidosis in adults with Stage 1 or Stage 2 polyneuropathy, and in Japan for the treatment of hATTR amyloidosis with polyneuropathy. ONPATTRO is an intravenously administered RNAi therapeutic targeting transthyretin (TTR). It is designed to target and silence TTR messenger RNA, thereby blocking the production of TTR protein before it is made. ONPATTRO blocks the production of TTR in the liver, reducing its accumulation in the bodys tissues in order to halt or slow down the progression of the polyneuropathy associated with the disease. For more information about ONPATTRO, visit ONPATTRO.com.

ONPATTRO (patisiran) lipid complex injection Important Safety Information

Infusion-Related Reactions

Infusion-related reactions (IRRs) have been observed in patients treated with ONPATTRO. In a controlled clinical study, 19 percent of ONPATTRO-treated patients experienced IRRs, compared to 9 percent of placebo-treated patients. The most common symptoms of IRRs with ONPATTRO were flushing, back pain, nausea, abdominal pain, dyspnea, and headache.

To reduce the risk of IRRs, patients should receive premedication with a corticosteroid, acetaminophen, and antihistamines (H1 and H2 blockers) at least 60 minutes prior to ONPATTRO infusion. Monitor patients during the infusion for signs and symptoms of IRRs. If an IRR occurs, consider slowing or interrupting the infusion and instituting medical management as clinically indicated. If the infusion is interrupted, consider resuming at a slower infusion rate only if symptoms have resolved. In the case of a serious or life-threatening IRR, the infusion should be discontinued and not resumed.

Reduced Serum Vitamin A Levels and Recommended Supplementation

ONPATTRO treatment leads to a decrease in serum vitamin A levels. Supplementation at the recommended daily allowance (RDA) of vitamin A is advised for patients taking ONPATTRO. Higher doses than the RDA should not be given to try to achieve normal serum vitamin A levels during treatment with ONPATTRO, as serum levels do not reflect the total vitamin A in the body.

Patients should be referred to an ophthalmologist if they develop ocular symptoms suggestive of vitamin A deficiency (e.g. night blindness).

Adverse Reactions

The most common adverse reactions that occurred in patients treated with ONPATTRO were upper respiratory-tract infections (29 percent) and infusion-related reactions (19 percent).

Hereditary transthyretin (TTR)-mediated amyloidosis (hATTR) is an inherited, progressively debilitating, and often fatal disease caused by mutations in the TTR gene. TTR protein is primarily produced in the liver and is normally a carrier of vitamin A. Mutations in the TTR gene cause abnormal amyloid proteins to accumulate and damage body organs and tissue, such as the peripheral nerves and heart, resulting in intractable peripheral sensory-motor neuropathy, autonomic neuropathy, and/or cardiomyopathy, as well as other disease manifestations. hATTR amyloidosis, represents a major unmet medical need with significant morbidity and mortality affecting approximately 50,000 people worldwide. The median survival is 4.7 years following diagnosis, with a reduced survival (3.4 years) for patients presenting with cardiomyopathy.

About RNAi

RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as a major scientific breakthrough that happens once every decade or so, and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines, known as RNAi therapeutics, is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam's RNAi therapeutic platform, function upstream of todays medicines by potently silencing messenger RNA (mRNA) the genetic precursors that encode for disease-causing or disease pathway proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases.

Angelika Amon, cell biologist who pioneered research on chromosome imbalance, dies at 53 – MIT News

Saturday, October 31st, 2020

Angelika Amon, professor of biology and a member of the Koch Institute for Integrative Cancer Research, died on Oct. 29 at age 53, following a two-and-a-half-year battle with ovarian cancer.

"Known for her piercing scientific insight and infectious enthusiasm for the deepest questions of science, Professor Amon built an extraordinary career and in the process, a devoted community of colleagues, students and friends," MIT President L. Rafael Reif wrote in a letter to the MIT community.

Angelika was a force of nature and a highly valued member of our community, reflects Tyler Jacks, the David H. Koch Professor of Biology at MIT and director of the Koch Institute. Her intellect and wit were equally sharp, and she brought unmatched passion to everything she did. Through her groundbreaking research, her mentorship of so many, her teaching, and a host of other contributions, Angelika has made an incredible impact on the world one that will last long into the future.

A pioneer in cell biology

From the earliest stages of her career, Amon made profound contributions to our understanding of the fundamental biology of the cell, deciphering the regulatory networks that govern cell division and proliferation in yeast, mice, and mammalian organoids, and shedding light on the causes of chromosome mis-segregation and its consequences for human diseases.

Human cells have 23 pairs of chromosomes, but as they divide they can make errors that lead to too many or too few chromosomes, resulting in aneuploidy. Amons meticulous and rigorous experiments, first in yeast and then in mammalian cells, helped to uncover the biological consequences of having too many chromosomes. Her studies determined that extra chromosomes significantly impact the composition of the cell, causing stress in important processes such as protein folding and metabolism, and leading to additional mistakes that could drive cancer. Although stress resulting from aneuploidy affects cells ability to survive and proliferate, cancer cells which are nearly universally aneuploid can grow uncontrollably. Amon showed that aneuploidy disrupts cells usual error-repair systems, allowing genetic mutations to quickly accumulate.

Aneuploidy is usually fatal, but in some instances extra copies of specific chromosomes can lead to conditions such as Down syndrome and developmental disorders including those known as Patau and Edwards syndromes. This led Amon to work to understand how these negative effects result in some of the health problems associated specifically with Down syndrome, such as acute lymphoblastic leukemia. Her expertise in this area led her to be named co-director of the recently established Alana Down Syndrome Center at MIT.

Angelikas intellect and research were as astonishing as her bravery and her spirit. Her labs fundamental work on aneuploidy was integral to our establishment of the center, say Li-Huei Tsai, the Picower Professor of Neuroscience and co-director of the Alana Down Syndrome Center. Her exploration of the myriad consequences of aneuploidy for human health was vitally important and will continue to guide scientific and medical research.

Another major focus of research in the Amon lab has been on the relationship between how cells grow, divide, and age. Among other insights, this work has revealed that once cells reach a certain large size, they lose the ability to proliferate and are unable to reenter the cell cycle. Further, this growth contributes to senescence, an irreversible cell cycle arrest, and tissue aging. In related work, Amon has investigated the relationships between stem cell size, stem cell function, and tissue age. Her labs studies have found that in hematopoetic stem cells, small size is important to cells ability to function and proliferate in fact, she posted recent findings on bioRxiv earlier this week and have been examining the same questions in epithelial cells as well.

Amon lab experiments delved deep into the mechanics of the biology, trying to understand the mechanisms behind their observations. To support this work, she established research collaborations to leverage approaches and technologies developed by her colleagues at the Koch Institute, including sophisticated intestinal organoid and mouse models developed by the Yilmaz Laboratory, and a microfluidic device developed by the Manalis Laboratory for measuring physical characteristics of single cells.

The thrill of discovery

Born in 1967, Amon grew up in Vienna, Austria, in a family of six. Playing outside all day with her three younger siblings, she developed an early love of biology and animals. She could not remember a time when she was not interested in biology, initially wanting to become a zoologist. But in high school, she saw an old black-and-white film from the 1950s about chromosome segregation, and found the moment that the sister chromatids split apart breathtaking. She knew then that she wanted to study the inner workings of the cell and decided to focus on genetics at the University of Vienna in Austria.

After receiving her BS, Amon continued her doctoral work there under Professor Kim Nasmyth at the Research Institute of Molecular Pathology, earning her PhD in 1993. From the outset, she made important contributions to the field of cell cycle dynamics. Her work on yeast genetics in the Nasmyth laboratory led to major discoveries about how one stage of the cell cycle sets up for the next, revealing that cyclins, proteins that accumulate within cells as they enter mitosis, must be broken down before cells pass from mitosis to G1, a period of cell growth.

Towards the end of her doctorate, Amon became interested in fruitfly genetics and read the work of Ruth Lehmann, then a faculty member at MIT and a member of the Whitehead Institute. Impressed by the elegance of Lehmanns genetic approach, she applied and was accepted to her lab. In 1994, Amon arrived in the United States, not knowing that it would become her permanent home or that she would eventually become a professor.

While Amons love affair with fruitfly genetics would prove short, her promise was immediately apparent to Lehmann, now director of the Whitehead Institute. I will never forget picking Angelika up from the airport when she was flying in from Vienna to join my lab. Despite the long trip, she was just so full of energy, ready to talk science, says Lehmann. She had read all the papers in the new field and cut through the results to hit equally on the main points.

But as Amon frequently was fond of saying, yeast will spoil you. Lehmann explains that because they grow so fast and there are so many tools, your brain is the only limitation. I tried to convince her of the beauty and advantages of my slower-growing favorite organism. But in the end, yeast won and Angelika went on to establish a remarkable body of work, starting with her many contributions to how cells divide and more recently to discover a cellular aneuploidy program.

In 1996, after Lehmann had left for New York Universitys Skirball Institute, Amon was invited to become a Whitehead Fellow, a prestigious program that offers recent PhDs resources and mentorship to undertake their own investigations. Her work on the question of how yeast cells progress through the cell cycle and partition their chromosomes would be instrumental in establishing her as one of the worlds leading geneticists. While at Whitehead, her lab made key findings centered around the role of an enzyme called Cdc14 in prompting cells to exit mitosis, including that the enzyme is sequestered in a cellular compartment called the nucleolus and must be released before the cell can exit.

I was one of those blessed to share with her a eureka moment, as she would call it, says Rosella Visintin, a postdoc in Amons lab at the time of the discovery and now an assistant professor at the European School of Molecular Medicine in Milan. She had so many. Most of us are lucky to get just one, and I was one of the lucky ones. Ill never forget her smile and scream neither will the entire Whitehead Institute when she saw for the first time Cdc14 localization: You did it, you did it, you figured it out! Passion, excitement, joy everything was in that scream.

In 1999, Amons work as a Whitehead Fellow earned her a faculty position in the MIT Department of Biology and the MIT Center for Cancer Research, the predecessor to the Koch Institute. A full professor since 2007, she also became the Kathleen and Curtis Marble Professor in Cancer Research, associate director of the Paul F. Glenn Center for Biology of Aging Research at MIT, a member of the Ludwig Center for Molecular Oncology at MIT, and an investigator of the Howard Hughes Medical Institute.

Her pathbreaking research was recognized by several awards and honors, including the 2003 National Science Foundation Alan T. Waterman Award, the 2007 Paul Marks Prize for Cancer Research, the 2008 National Academy of Sciences (NAS) Award in Molecular Biology, and the 2013 Ernst Jung Prize for Medicine. In 2019, she won the Breakthrough Prize in Life Sciences and the Vilcek Prize in Biomedical Science, and was named to the Carnegie Corporation of New Yorks annual list of Great Immigrants, Great Americans. This year, she was given the Human Frontier Science Program Nakasone Award. She was also a member of the NAS and the American Academy of Arts and Sciences.

Lighting the way forward

Amons perseverance, deep curiosity, and enthusiasm for discovery served her well in her roles as teacher, mentor, and colleague. She has worked with many labs across the world and developed a deep network of scientific collaboration and friendships. She was a sought-after speaker for seminars and the many conferences she attended. In over 20 years as a professor at MIT, she has mentored more than 80 postdocs, graduate students, and undergraduates, and received the School of Sciences undergraduate teaching prize.

Angelika was an amazing, energetic, passionate, and creative scientist, an outstanding mentor to many, and an excellent teacher, says Alan Grossman, the Praecis Professor of Biology and head of MITs Department of Biology. Her impact and legacy will live on and be perpetuated by all those she touched.

Angelika existed in a league of her own, explains Kristin Knouse, one of Amons former graduate students and a current Whitehead Fellow. She had the energy and excitement of someone who picked up a pipette for the first time, but the brilliance and wisdom of someone who had been doing it for decades. Her infectious energy and brilliant mind were matched by a boundless heart and tenacious grit. She could glance at any data and immediately deliver a sharp insight that would never have crossed any other mind. Her positive attributes were infectious, and any interaction with her, no matter how transient, assuredly left you feeling better about yourself and your science.

Taking great delight in helping young scientists find their own eureka moments, Amon was a fearless advocate for science and the rights of women and minorities and inspired others to fight as well. She was not afraid to speak out in support of the research and causes she believed strongly in. She was a role model for young female scientists and spent countless hours mentoring and guiding them in a male-dominated field. While she graciously accepted awards for women in science, including the Vanderbilt Prize and the Women in Cell Biology Senior Award, she questioned the value of prizes focused on women as women, rather than on their scientific contributions.

Angelika Amon was an inspiring leader, notes Lehmann, not only by her trailblazing science but also by her fearlessness to call out sexism and other -isms in our community. Her captivating laugh and unwavering mentorship and guidance will be missed by students and faculty alike. MIT and the science community have lost an exemplary leader, mentor, friend, and mensch.

Amons wide-ranging curiosity led her to consider new ideas beyond her own field. In recent years, she has developed a love for dinosaurs and fossils, and often mentioned that she would like to study terraforming, which she considered essential for a human success to life on other planets.

It was always amazing to talk with Angelika about science, because her interests were so deep and so broad, her intellect so sharp, and her enthusiasm so infectious, remembers Vivian Siegel, a lecturer in the Department of Biology and friend since Amons postdoctoral days. Beyond her own work in the lab, she was fascinated by so many things, including dinosaurs dreaming of taking her daughters on a dig lichen, and even life on Mars.

Angelika was brilliant; she illuminated science and scientists, says Frank Solomon, professor of biology and member of the Koch Institute. And she was intense; she warmed the people around her, and expanded what it means to be a friend.

Amon is survived by her husband Johannes Weis, and her daughters Theresa and Clara Weis, and her three siblings and their families.

ETFs in Focus on Bayer’s Bet on Gene Therapy – Zacks.com

Saturday, October 31st, 2020

Merger and acquisition activities have heated up in recent months and the niche spaces are in the limelight. After the telemedicine industry, gene therapy stocks jumped on the bandwagon. Gene therapy is a technique that uses genes to treat or prevent disease.

German drugmaker Bayer has made a big bet on gene therapy by announcing the acquisition of U.S. biotech firm Asklepios BioPharmaceutical for as much as $4 billion. The proposed acquisition will provide Bayer access to the adeno-associated virus (AAV) gene therapy platform and a pipeline led by clinical-phase treatments for Parkinsons, Pompe disease and congestive heart failure. Notably, AAV therapies offer improved efficacy, immune response, and tissue and organ specificity.

Additionally, the transaction will complements Bayers 2019 acquisition of BlueRock Therapeutics and advances its efforts to create platforms with the potential to have an impact on multiple therapeutic areas (read: Genomics ETFs Surge on Nobel Prize for Gene-Editing Pioneers).

Under the terms of the deal, Bayer will pay an upfront consideration of $2 billion and potential success-based milestone payments of up to $ billion. About 75 % of the potential milestone-based contingent payments are expected to be due during the course of the next five years and the remaining amount thereafter.

The deal, pending regulatory approvals, is expected to close during the fourth quarter of 2020. Once the deal closes, Bayer will allow Asklepios, known as AskBio, to operate autonomously as part of a new cell and gene therapy unit in a bid to preserve its entrepreneurial culture. The cell and gene therapy unit will bundle Bayer's activities in this area moving forward in order to establish an innovation ecosystem for the participating partners, the German company said (see: all the Healthcare ETFs here).

Better Repair of Nerve Insulation May Lead to New MS Treatments – Multiple Sclerosis News Today

Saturday, October 31st, 2020

There may be a better way of repairing the insulation surrounding damaged neurons that could lead to new treatments for multiple sclerosis (MS), a study suggests.

The data showed that blocking the protein sphingomyelin hydrolase neutral sphingomyelinase 2, or nSMase2, could improve the quality of the myelin surrounding nerve cell fibers, and stabilize its structure. nSMase2 is responsible for breaking down sphingomyelin, which is a type of lipid (fat) molecule present in that protective myelin sheath.

The study, Inhibition of neutral sphingomyelinase 2 promotes remyelination, was published in the journal Science Advances.

MS is caused by the attack by immune cells to the bodys own myelin, a fatty insulation provided by oligodendrocyte cells that cover the long branches that extend from nerve cells, which are called axons. When myelin is destroyed called demyelination the connections between neurons become defective and MS symptoms arise.

Most individuals with relapsing-remitting MS (RRMS), an intermittent form of multiple sclerosis, have acute episodes of demyelination. RRMS may evolve to secondary progressive MS (SPMS), in which progressive neurological deterioration occurs and myelin can no longer repair itself.

Suppressing the immune system has worked to treat relapsing-remitting MS, but it doesnt protect from the eventual advancement to progressive MS, for which there arent any good treatments on the market, Norman Haughey, PhD, professor of neurology at the Johns Hopkins University School of Medicine and the studys senior author, said in a press release.

Now, a team led by researchers at Johns Hopkins suggested that the use of certain compounds may be able to prevent RRMS from evolving to SPMS.

In previous studies, the team analyzed the composition of the myelin surrounding nerves near injury sites in the brain tissue of cadavers with MS. Compared with other nerves, these looked misshapen and had higher levels of ceramide and lower levels of sulfatide both lipid (fat) molecules.

Ceramide plays a role in MS by regulating the curvature and compaction of myelin. However, when in excess, it can form bumps on the surface of myelin preventing it from wrapping tightly around nerves.

In the new study, the team analyzed modifications in the lipid composition of myelin following remyelination in cuprizone-treated mice a mouse model of MS in which myelin loss and oligodendrocyte destruction are caused by the toxic agent cuprizone. Cuprizone was given to the mice through their diet for 26 days.

The results showed that the myelin was able to repair itself, although the increase of ceramide produced a disorganized and decompacted myelin structure. The researchers believe the overproduction of ceramide during remyelination is the result of the action of the enzyme nSMase2 that converts sphingomyelin to ceramide. nSMase2 is activated by brain inflammation.

Oligodendrocyte progenitor cells (OPCs) are activated and recruited to damaged sites following demyelination. These cells then differentiate into myelinating oligodendrocytes to repair denuded axons. For oligodendrocyte regeneration, inflammation is functionally important.

The scientists showed that inflammatory cytokines, namely tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta), promote a protective and regenerative response in OPCs. However, that turns into a harmful response, promoting apoptosis (cell death) as the OPCs differentiate into oligodendrocytes.

Moreover, in experiments using antibodies (immunostaining), the researchers found that the response of OPCs and oligodendrocytes to inflammatory cytokines may be regulated by the nSMase2 enzyme. Through further investigation, the team found that the expression of nSMase2 modifies the cellular response to inflammatory cytokines such as TNF-alpha.

Our findings suggest that expression of nSMase2 modifies the cellular response to inflammation, from being protective in OPCs (when nSMase2 is not expressed) to damaging in myelinating oligodendrocytes, the researchers wrote.

The team then assessed whether pharmacological inhibition of nSMase2 protected myelinated axons. This was done by testing cambinol, a compound that blocks nSMase, in the cuprizone mouse model. The results showed that blocking nSMase2 prevented the increased production of ceramide and its incorporation in regenerated myelin.

Next, the researchers determined whether inhibition of nSMase2 during the remyelination process modified the lipid content of myelin. The mice were fed a cuprizone-containing diet for 28 days, to induce myelin damage. This was followed by cambinol for 28 days, after which the mice were returned to a normal diet.

Cambinol treatment caused the myelin to grow back tightly around the nerve cells; the myelin produced appeared as it did before the cuprizone-induced damage. The treatment did not completely restore the lipid composition of myelin, but appeared to increase its stability protecting neurons, the team noted.

Finally, genetic deletion of nSMase2 in myelinating oligodendrocytes also was found to normalize the amount of ceramide and increase the thickness and compaction of myelin, thus stabilizing the structure of remyelinated axons.

Pharmacological inhibition or genetic deletion of nSMase2 in myelinating oligodendrocytes normalized the ceramide content of remyelinated fibers and increased thickness and compaction. These results suggest that inhibition of nSMase2 could improve the quality of myelin and stabilize structure, the researchers wrote, adding that amore stable myelin structure is likely to be less susceptible to secondary demyelination.

We think these findings are a big step toward improving the quality and composition of myelin following a flare-up, Haughey said.

The team now plans to determine the impacts of other abnormal lipid levels, apart from ceramide, and determine if myelin maintains its function when returned to its correct structure. After this, the researchers hope it will be possible to consider inhibitors of nSMase2 for use in human trials.

Be Biopharma, AavantiBio Launch With Millions in Financing to Support Therapeutic Goals – BioSpace

Friday, October 23rd, 2020

Its a day of firsts, with the launch of two new Cambridge, Mass.-based life sciences companies, Be Biopharma, with a focus on B cell malignancies, and AavantiBio, a gene therapy company aimed at treating rare genetic diseases.

AavantiBio launched with a $107 million Series A financing round, which includes not only a $15 million equity investment from Sarepta Therapeutics, but also an experienced executive in Alexander Bo Cumbo to helm the startup. The companys lead asset is a gene therapy treatment for Friedreichs Ataxia (FA), a rare inherited genetic disease that causes cardiac and central nervous system dysfunction.

AavantiBios gene therapy builds on the work of its co-founders, renowned gene therapy researchers Barry Byrne and Manuela Corti, who have researched FA and other genetic disorders. In addition to the foundational work of Byrne and Corti, the startup will also benefit from strategic partnerships with the University of Floridas renowned Powell Gene Therapy Center and the MDA Care Center at UF Health where Byrne and Corti maintain their research and clinical practices.

Cumbo, who spent eight years at Sarepta as chief commercial officer, will serve as the first chief executive officer of AavantiBio. He said his time at Sarepta has been incredibly rewarding as that company emerged as a pioneer in treating Duchenne muscular dystrophy and limb-girdle muscular dystrophy patients and ultimately transformed into a genetic medicine leader.

It has been a privilege to contribute to this growth and play a role in serving these communities. As I look ahead to the bright future of AavantiBio and the exciting opportunity to lead this innovative company, this same dedication to serving unmet patient needs and to leveraging deep scientific expertise will be core to our mission. I am also thrilled to continue to collaborate with the talented team at Sarepta, said Cumbo, who will continue to serve as an adviser to Sarepta through the end of 2020.

Sarepta CEO Doug Ingram praised Cumbos work over the past eight years and said he built a first-in-class rare disease commercial organization. As a partner with AavantiBio, Ingram said he looks forward to a continued relationship with Cumbo and AavantiBios efforts to advance therapies for FA and other rare diseases.

In addition to Sarepta, AavantiBios Series A was supported by Perceptive Advisors, Bain Capital Life Sciences and RA Capital Management.

Be Biopharma launched with a $52 million Series A financing round. The company will use the funds to engineer B cells to treat a range of diseases. B cells are prolific protein producers that can be collected from peripheral blood, have a programmable lifetime that could last decades, can target specific tissues, and have broad, customizable functionality.

The company intends to build on the work of co-founders David Rawlings and Richard James conducted at Seattle Childrens Research Institute. Rawlings said the goal is to build new class of engineered B cell medicines that will provide direct control over the power of humoral immunity and transform the prognosis for patients who currently have limited treatment options.

Be Biopharma is helmed by David Steinberg, a co-founder of the company and a partner at Longwood Fund, one of the supporters of the Series A.

Be Bio is capitalizing on the unique attributes of B cells to create a new category of medicine that is distinct from traditional cell or gene therapy. B cells can be engineered to express a wide variety of proteins, have the potential to generate durable responses, and can be dose-titrated and administered multiple times without the need for toxic preconditioning, Steinberg said in a statement. Moreover, the varied functions of B cells suggest that B cell medicines can address a range of conditions including autoimmune diseases, cancer, and monogenic disorders, as well as enhance the immune response to infectious pathogens. We believe Be Bio is at the forefront of a new approach to fighting disease.

In addition to Longwood Fund, the Series A financing round was supported by investment leaders Atlas Venture and RA Capital Management. Alta Partners and Takeda Ventures also supported the financing round.

Use of Genetic Sequencing to Track SARS-CoV-2 Mutations Can Improve Diagnostic Testing Accuracy and Vaccine Effectiveness – HospiMedica

Friday, October 23rd, 2020

Scientists are tracking the SARS-CoV-2 virus that causes COVID-19 by sequencing the genome of virus samples collected from diagnostic testing. Using next generation sequencing on SARS-CoV-2 will help accurately diagnose the novel coronavirus, identify mutations and track its history.

A study by scientists at the UNC School of Medicine (Chapel Hill, NC, USA) has shown how next generation genetic sequencing can track mutations in the SARS-CoV-2 virus, which can in effect help with transmission tracing, diagnostic testing accuracy and vaccine effectiveness. This type of virus monitoring is also important in diagnostic testing. Much of the testing developed to diagnose COVID-19 looks for one portion of the gene sequence that causes the novel coronavirus. If that sequence mutates, the test is no longer accurate and results will be affected.

Their recent study is the largest to focus on suburban and rural communities in which the researchers were able to reconstruct the mutational landscape of cases seen at the UNC Medical Center. Within their study, the team of scientists did find variations in the virus genetic sequence, but fortunately none of the variations were located in the portion of the virus targeted in common diagnostic testing. 175 samples from confirmed COVID-19-positive patients were analyzed, out of which 57% carried the spike D614G variant noted in similar studies. The presence of this variant is associated with a higher genome copy number and its prevalence has expanded throughout the pandemic.

The researchers will continue using NGS to track the SARS-CoV-2 virus through the remainder of 2020. The goal is to enroll every patient at UNC Hospitals with flu or respiratory symptoms for COVID-19 diagnostic testing. These samples will be sequenced and compiled to form a comprehensive profile of any virus that these patients carry, information that will continue to help a community of researchers in their fight against SARS-CoV-2 and potentially novel coronaviruses.

We are concerned about future mutations though, said Dirk Dittmer, PhD, professor of microbiology and immunology at the UNC School of Medicine, and senior author of the study. It is inherent in a virus nature to mutate. Changes in other areas of the genetic sequence can not only disrupt testing, but hinder the effectiveness of vaccines.

Because we are only looking at one gene sequence for the virus, we have told the FDA that we will continually monitor for changes in this gene sequence so that we can be assured that our test is still reliable, said Melissa Miller, PhD, director of UNC Medical Center Microbiology and Molecular Microbiology Laboratories, and a co-author of the study. NGS will help us do that.
