ALDERLEY PARK, England--(BUSINESS WIRE)--Charles River Laboratories International, Inc. (NYSE: CRL) and Cure AP-4, a non-profit foundation dedicated to raising funds and awareness about Adapter-Protein 4 Hereditary Spastic Paraplegia (AP-4 HSP), today announced a manufacturing collaboration. Charles River, a contract research and development manufacturing organization (CRO/CDMO), will provide High Quality (HQ) plasmid DNA for Cure AP-4s Phase I/II gene therapy trials against AP-4 HSP.

Founded in 2016 by the families of two newly diagnosed AP-4 HSP (SPG47) patients, Molly Duffy and Robbie Edwards, Cure AP-4s gene therapy treatment will look to address the root cause of AP-4 HSP, a rare neurodegenerative disorder, and is intended as a one-time, curative treatment for the patient.

What is AP-4 HSP? AP-4 HSP, also known as AP-4 Deficiency Syndrome, includes four sub-types of HSP: SPG47, SPG50, SPG51 and SPG52. Each of these HSP sub-types is associated with a defective autosomal recessive gene which causes a failure in the AP-4 Adaptor Complex. The phenotype and prognosis for each sub-type is extremely similar. Patients afflicted with any of the AP-4 HSP genetic disorders generally present with symptoms including global developmental delay, microcephaly, seizures, brain malformation, and hypotonia (low-muscle tone). The few patients who learn to walk independently tend to lose that ability a few months or few years later as they develop hypertonia (high-muscle tone) and muscle spasticity. Of the 249 currently confirmed global AP-4 HSP cases, most patients experience mobility in some or all extremities as the disorder progresses and are severely intellectually challenged.

Plasmid DNA Manufacturing ServicesThe collaboration will leverage Charles Rivers market leading expertise in plasmid DNA production, specifically HQ plasmid, which combines key features of GMP manufacture with rapid turnaround times to accelerate the timeline to clinic. DNA plasmids are a critical starting material for many cell and gene therapy therapeutics and demand continues to outstrip supply. In response to this, Charles River recently announced the opening of a state-of-the-art HQ plasmid manufacturing center of excellence to address these supply shortages and support the growing needs of the cell and gene therapy field.

Charles River, with the acquisitions of Cognate BioServices, Cobra Biologics, and Vigene Biosciences in 2021, has extended its comprehensive cell and gene therapy portfolio to include CDMO capabilities spanning viral vector, plasmid DNA and cellular therapy production for clinical through to commercial supply.

About Cure AP-4Cure AP-4, originally known as Cure SPG47, was founded in 2016 by the families of two newly diagnosed SPG47 patients, Molly Duffy and Robbie Edwards. At the time there were only nine other documented cases worldwide, and due to the extreme rarity of the disorder there are no known treatments or cures.
