Partial Clinical Hold Lifted on Adaptimmune T-cell Therapy
FDA has removed a partial clinical hold on a Adaptimmune Therapeutics planned study of its NY‑ESO SPEAR (Specific Peptide Enhanced Affinity Receptor) T-cell therapy in myxoid round cell liposarcoma (MRCLS). The hold was issued in August as part of the agency’s request for additional chemistry, manufacturing and controls information and answers to certain trial design questions prior to the trial commencing , the company says. “Adaptimmune is running a number of different studies with its NY-ESO program and continues to enroll patients in synovial sarcoma, ovarian, and lung cancer trials in the U.S.,” it adds.
Under a revised protocol, Adaptimmune will initiate a study in up to 15 MRCLS patients. Patient screening is expected to begin before year end, and results from the study will be used to decide whether a potential future registration trial will be planned, he company says.
Adaptimmune is a clinical stage biopharmaceutical company focused on novel cancer immunotherapy products based on its SPEAR (Specific Peptide Enhanced Affinity Receptor) T-cell platform. Established in 2008, the company says it aims to utilize the body’s own T-cells to target and destroy cancer cells by using engineered, increased affinity T-cell receptors to strengthen natural patient T-cell responses.
