Bellicum Pharmaceuticals Provides Interim Data for BPX-601 in Patients with Metastatic Pancreatic Cancer for Presentation at ASCO Annual Meeting
Data provides further evidence that GoCAR-T® technology boosts expansion and persistence of therapeutic T cells in patients
T cell expansion and persistence greater in patients who received lymphodepletion with cyclophosphamide plus fludarabine (Flu/Cy) compared to Cy alone
Of 13 patients evaluable for efficacy treated with BPX-601 and a single dose of rimiducid, 8 (62%) achieved stable disease, including 3 with tumor shrinkage of 10% to 24%
Adverse events were generally consistent with those experienced by advanced cancer patients undergoing cytotoxic chemotherapy and other cancer immunotherapies
BPX-601, the company’s first GoCAR-T® product candidate, incorporates iMC, Bellicum’s inducible co-activation domain. iMC, inducible MyD88/CD40 via administration of rimiducid, is designed to provide a powerful boost to T cell proliferation and persistence and enable the CAR-T to override key immune inhibitory mechanisms, including PD-1 and TGF-beta.
“These updated results in patients with advanced pancreatic cancer showed that more intense lymphodepletion with Flu/Cy resulted in increased BPX-601 CAR-T cell expansion and prolonged persistence in patients treated with single-dose rimiducid,” said
“I am excited that additional data from our BPX-601 trial continue to support the potential of our GoCAR-T technology platform. Our data presentation at
Study Overview and Results
This Phase 1/2 trial has been designed to enroll patients with PSCA-positive pancreatic cancer to assess the safety, biologic and clinical activity of BPX-601. As of
The poster, titled Ligand-Inducible, Prostate Stem Cell Antigen (PSCA)-Directed GoCAR-T® Cells in Advanced Solid Tumors: Preliminary Results with Cyclophosphamide (Cy) ± Fludarabine (Flu) Lymphodepletion (LD), may be found on the Bellicum website under Abstracts and Presentations.
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 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 solid tumors expressing prostate stem cell antigen (PSCA), including pancreatic, gastric, and prostate cancers.
Bellicum is a clinical stage biopharmaceutical company striving to deliver cures through controllable cell therapies. The company’s next-generation product candidates are differentiated by powerful cell signaling technologies designed to produce more effective CAR-T and allogeneic T cell therapies. Bellicum’s lead GoCAR-T® candidate, BPX-601, is designed to be a more efficacious CAR-T cell product capable of overriding key immune inhibitory mechanisms. Bellicum’s rivo-cel product candidate is an allogeneic polyclonal T cell therapy that has shown promising clinical trial results in reducing leukemia relapse after a stem cell transplant.
