Bellicum Reports Clinical Hold Placed on BPX-601 Phase 1/2 Clinical Trial

HOUSTON, TX, USA I December 07, 2020 I Bellicum Pharmaceuticals, Inc. (NASDAQ:BLCM), a leader in developing novel, controllable cellular immunotherapies for cancers, today announced that it has been notified by the U.S. Food and Drug Administration (FDA) that a clinical hold has been placed on patient enrollment and dosing in an ongoing Phase 1/2 dose-escalation clinical trial evaluating BPX-601 in patients with previously treated metastatic pancreatic or prostate cancer. The FDA is taking this action due to the death of a pancreatic cancer patient in the trial reported to the agency by the company. The clinical investigator and Bellicum classified the patient death as unrelated to BPX-601 and rimiducid.

The company plans to work diligently with the FDA to address the agency’s questions and fulfill the requirements for resuming the trial. The clinical hold does not affect the company’s plans to initiate enrollment in the Phase 1/2 clinical trial of BPX-603, a dual switch GoCAR-T®, in patients with HER2+ solid tumors by the end of the year.

About BPX-601

BPX-601, the company’s first GoCAR-T® product candidate, incorporates iMC, Bellicum’s inducible co-activation domain. iMC (inducible MyD88/CD40) is designed to provide a powerful boost to T cell proliferation and persistence, production of immunomodulatory cytokines and enable the CAR-T to override key immune inhibitory mechanisms, including PD-1 and TGF-beta. BPX-601 is being evaluated as a treatment for pancreatic and prostate tumors expressing prostate stem cell antigen (PSCA).
