Bellicum and Astellas Announce License Agreement for Cancer Target PSCA in Cell and Gene Therapy
Bellicum obtains rights to develop adoptive cell therapies targeting tumors expressing PSCA; Astellas or Agensys retains option for commercial rights in Japan

Houston and Tokyo, December 10, 2015 - Bellicum Pharmaceuticals, Inc. (NASDAQ: BLCM, “Bellicum”) and Astellas Pharma Inc. (TSE: 4503, “Astellas”) today announced that Agensys, Inc. (“Agensys”), an affiliate of Astellas, and Bellicum have entered into a global license agreement, granting Bellicum rights to develop and commercialize adoptive cell therapies, including CAR-T cells, for tumors expressing Prostate Stem Cell Antigen (PSCA) using PSCA technology, both in-licensed and developed at Agensys.

PSCA is a cancer antigen expressed in many malignancies, including prostate, pancreatic, bladder, esophagus, and gastric cancers. Bellicum is developing BPX-601, a GoCAR-T™ product candidate targeting PSCA that has demonstrated robust anti-tumor activity in preclinical studies. GoCAR-T is a proprietary Bellicum technology in which an MC (MyD88/CD40) molecular switch is designed to enable pharmacologic control over the activation, proliferation and persistence of the GoCAR-T cells in a patient.

“PSCA is an attractive target for our CAR-T cell technology and the license agreement allows Bellicum to advance BPX-601 into a number of cancers where there is a significant unmet medical need,” commented Bellicum’s President and CEO Thomas J. Farrell. “We look forward to the expected advancement of BPX-601 into clinical development in the first half of 2016 for the initial target indication of pancreatic cancer.” 

“We are pleased to enter into this agreement with Bellicum whose breakthrough technology has high potential to advance innovative cancer immune cell therapies. With this license, we expect to provide a new therapeutic option to cancer patients as early as possible with the benefit of the two companies’ technologies. This collaboration is one piece of our strategy in cancer immunotherapy, where Astellas is actively engaged, and we will continue to make aggressive investments in the field of cancer immunotherapy including cancer cell therapies,” said Kenji Yasukawa, Ph.D., Chief Strategy Officer, Astellas.

Under the terms and conditions of the license agreement, Agensys will receive an upfront license fee, and is eligible for clinical and sales milestones, as well as single-digit royalties on the sales of any products developed pursuant to the license. Astellas or Agensys retains the option for commercialization of any product targeting PSCA based on Bellicum’s CAR-T cell technology (e.g., BPX-601) in Japan. If the option is exercised, Bellicum would receive an option fee from Astellas or Agensys, and the amount for certain clinical and sales milestones to be paid to Agensys would be reduced. Bellicum would also receive royalties from Astellas or Agensys based upon sales of such product in Japan.
