Orchard Therapeutics signs manufacturing services agreement with PCT Cell Therapy Services

Under the terms of this new agreement, PCT will provide GMP-compliant manufacturing services for Orchard’s lead product, OTL-101, an autologous ex-vivo gene therapy for the treatment of ADA-SCID.

PCT is a leading provider of contract services for the development and manufacture (CDMO) of cell-based therapeutic and regenerative medicine products. PCT has previously provided a Strategic Manufacturing Assessment (SMA) and manufacturing process development services to Orchard. Under the terms of this new agreement, PCT will provide GMP-compliant manufacturing services for Orchard’s lead product, OTL-101, an autologous ex-vivo gene therapy for the treatment of adenosine deaminase deficiency severe combined immunodeficiency (ADA-SCID). ADA-SCID is a rare inherited disorder of the immune system caused by mutations in the gene encoding for the enzyme adenosine deaminase, which result in a severe deficiency in white blood cells and life-threatening infections. In the absence of treatment, ADA-SCID is fatal within the first months of life.

This agreement represents another key step in Orchard’s strategy to establish a global supply chain to deliver autologous ex-vivo gene therapy medicinal products to patients with devastating genetic diseases. Stewart Craig, Orchard’s Chief Manufacturing Officer commented: “We are very pleased to extend our relationship with PCT into a full GMP manufacturing services agreement for OTL-101. As a world-leading CDMO for cell-based therapeutic products, this is an important step in advancing our lead program for the treatment of children afflicted with ADA-SCID.”

To date, over 40 ADA-SCID patients have been treated with Orchard’s autologous ex-vivo lentiviral gene therapy at University of California Los Angeles (UCLA), US and at the Great Ormond Street Hospital (GOSH) in London, UK. All patients have survived (100% overall survival) and the treatment has been shown to restore patients’ immune function, with a favourable safety profile.

Robert Preti, CEOand President of PCT, commented: “Expansion of our agreement with Orchard to now include clinical manufacturing in support of their ADA-SCID gene therapy is testament to our successful collaboration and our dedicated stewardship of this important program. The clinical results are cause for hope among this patient population and we look forward to helping advance this important new therapeutic towards commercialization.”
