StemCell Therapy

NEW YORK, Oct. 29, 2020 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, today provided an update on the potential pathway to marketing approval for its lead product candidate remestemcel-L. It also provided a financial report for the first quarter ended September 30, 2020.

Mesoblast Chief Executive Dr Silviu Itescu stated: We believe the immunomodulatory properties of remestemcel-L position this potential therapy at the forefront of treatment for severe and life-threatening inflammatory conditions, including COVID-19 acute respiratory distress syndrome (ARDS) and steroid-refractory acute graft versus host disease (SR-aGVHD). We are pursuing an accelerated approval pathway for remestemcel-L in the treatment of children with SR-aGVHD, and a parallel approval pathway for COVID-19 ARDS if the randomized controlled Phase 3 trial is positive.

Children with Steroid-Refractory Acute Graft Versus Host DiseaseIn August, the Oncologic Drugs Advisory Committee (ODAC)1 of the United States Food and Drug Administration (FDA) voted 9:1 that the available data from a single-arm Phase 3 trial and evidence from additional studies support the efficacy of remestemcel-L in pediatric patients with SR-aGVHD. Despite the overwhelming ODAC vote, in September the FDA recommended that Mesoblast conduct at least one additional randomized, controlled study in adults and/or children to provide further evidence of the effectiveness of remestemcel-L for SR-aGVHD.

Mesoblast believes that remestemcel-L meets the criteria for accelerated approval as there are currently no approved treatments for this life-threatening condition in children under 12. Mesoblast has formally requested a Type A meeting with the FDA to discuss a potential accelerated approval of the Biologics License Application (BLA) for remestemcel-L for the treatment of SR-aGVHD in children, with an additional randomized controlled study in patients 12 years and older as a post-approval requirement. Mesoblast expects this meeting will occur in November.

Adults with COVID-19 ARDSAs cases of COVID-19 surge in the United States and globally, deaths continue to increase from ARDS in ventilator-dependent patients as a result of an overactive immune response in the lungs to COVID-19. It is now evident that in both adults and children COVID-19 causes severe inflammation of other organ systems in addition to the lungs, including the heart, brain and kidneys. The immunomodulatory mechanism of action of remestemcel-L may be beneficial in the treatment of ARDS as well as in involvement of other organ systems.

Indeed, nine of 12 ventilator-dependent adult patients with COVID-19 ARDS who received two doses of remestemcel-L under emergency compassionate use at New Yorks Mt Sinai Hospital were successfully discharged within a median of 10 days. Additionally, two COVID-19 infected children with multisystem inflammatory syndrome (MIS-C) who received remestemcel-L for severe heart failure fully recovered heart function and were discharged within 30 hours of the second dose.

To confirm these pilot data, remestemcel-L is being evaluated for its potential to reduce mortality in a Phase 3 randomized controlled trial of up to 300 ventilator-dependent adults with moderate or severe COVID-19 ARDS. The dosing regimen in the Phase 3 is the same as in the pilot trial. Trial enrollment across more than 20 hospitals in the United States has surpassed 50% of the total 300 patient target. The trials first 135 patients will complete 30 days of follow up during October, after which the independent Data Safety Monitoring Board (DSMB) will perform an interim analysis of the trials primary endpoint of all-cause mortality within 30 days of randomization. The DSMB is expected to inform Mesoblast in early November on whether the trial should proceed as planned, or should stop early. A further interim analysis is planned after 60% of the trial has been enrolled.

Crohns DiseaseAccording to recent estimates, more than three million people (1.3%) in the United States alone have inflammatory bowel disease, with more than 33,000 new cases of Crohns disease and 38,000 new cases of ulcerative colitis diagnosed every year.2-4 Despite recent advances, approximately 30% of patients are primarily unresponsive to anti-TNF agents and even among responders, up to 10% will lose their response to the drug every year. Up to 80% of patients with medically-refractory Crohns disease eventually require surgical treatment of their disease,5 which can have a devastating impact on quality of life.

A randomized, controlled study of remestemcel-L delivered by an endoscope directly to the areas of inflammation and tissue injury in up to 48 patients with medically refractory Crohns disease and ulcerative colitis has commenced at Cleveland Clinic. Mesoblasts objective is to confirm the potential for remestemcel-L to induce luminal healing and early remission in a wider spectrum of diseases with severe inflammation of the gut, in addition to SR-aGVHD. The investigator-initiated study at Cleveland Clinic is the first in humans using local cell delivery in the gut, and will enable Mesoblast to compare clinical outcomes using this delivery method with results from an ongoing randomized, placebo-controlled trial in patients with biologic-refractory Crohns disease where remestemcel-L was administered intravenously.

Chronic Heart FailureIn the United States alone, of more than 6.5 million patients with chronic heart failure, there are more than 1.3 million patients with advanced stage of the disease.6 The objective of treatment with Mesoblasts allogeneic cellular product candidate REVASCOR is to reduce or reverse the severe inflammatory process in the damaged heart of these patients, and thereby prevent or delay further progression of heart failure or death. In an earlier randomized placebo-controlled 60-patient Phase 2 trial, a single intra-myocardial injection of REVASCOR at the dose administered in the subsequent Phase 3 trial prevented any hospitalizations or deaths over three years of follow-up in patients with advanced chronic heart failure. Results from Mesoblasts randomized placebo-controlled Phase 3 trial in patients with advanced forms of New York Heart Association Class II or Class III disease are expected during Q4 CY2020.

Chronic Low Back PainThere is a significant need for a safe, efficacious and durable treatment in patients with chronic low back pain due to severely inflamed degenerative disc disease, affecting over 3.2 million patients in the United States and approximately 4 million in the EU5.7 Results from a Phase 3 randomized placebo-controlled trial evaluating Mesoblasts product candidate in patients with chronic low back pain due to degenerative disc disease are expected during Q4 CY2020. In parallel, Mesoblast and its partner Grnenthal GmbH are collaborating on the clinical protocol for a confirmatory Phase 3 trial in Europe.

Cash Flow Report for the First Quarter FY2021Cash on hand at the end of the quarter was US$108.1 million. Over the next 12 months, Mesoblast may have access to an additional US$67.5 million through existing financing facilities and strategic partnerships.

Total Operating Activities excluding product inventory resulted in net cash usage of US$23.0 million in the quarter ended September 30, 2020. In addition, $5.2 million was invested in RYONCIL (remestemcel-L) commercial inventory in anticipation of product launch for either children with SR-aGVHD or COVID-19 patients with moderate to severe ARDS.
