Orchard Therapeutics Announces OTL-200 Granted Regenerative Medicine Advanced Therapy (RMAT) Designation by FDA for the Treatment of Metachromatic Leukodystrophy (MLD)

Interactions with FDA anticipated by mid-2021 to determine the BLA filing strategy for OTL-200

BOSTON and LONDON, Jan. 14, 2021 (GLOBE NEWSWIRE) — Orchard Therapeutics, a global gene therapy leader, today announced that the U.S. Food and Drug Administration (FDA) has granted Regenerative Medicine Advanced Therapy (RMAT) designation to OTL-200, an investigational ex vivo autologous hematopoietic stem cell (HSC) gene therapy for the treatment of early-onset metachromatic leukodystrophy (MLD). In late 2020, the FDA cleared the company’s Investigational New Drug (IND) application for OTL-200, and the therapy also recently was approved in the European Union (EU) under the brand name, LibmeldyTM.  

“Receipt of RMAT designation for OTL-200 underscores both the severe nature of MLD and the transformative potential of the therapy for young patients suffering from this devastating, fatal neurodegenerative condition,” said Bobby Gaspar, M.D., Ph.D., chief executive officer, Orchard Therapeutics. “Alongside our open IND, RMAT designation provides an opportunity for enhanced interactions with the FDA to determine the optimal path to submit a Biologics License Application (BLA) for OTL-200 in the U.S.”

Established under the 21st Century Cures Act, the RMAT designation program was created to expedite the development and review of regenerative medicine therapies intended to treat, modify, reverse or cure a serious condition. The FDA granted Orchard RMAT designation for OTL-200 based on data submitted on 39 patients, including 9 patients from the U.S., who have received OTL-200 as part of clinical studies and compassionate use programs conducted at the San Raffaele-Telethon Institute for Gene Therapy (SR-Tiget) in Milan, Italy. This data set includes post-treatment follow-up data of up to eight years in the earliest treated patients in these programs.

“We look forward to continued engagement with the FDA in the coming months to discuss the comprehensive data set we have already collected in the OTL-200 clinical development program and agree on the potential next steps on the regulatory path to approval for this innovative gene therapy,” said Anne Dupraz, chief regulatory officer at Orchard.
