Allogene Appoints Zachary J. Roberts, M.D., Ph.D. as Executive Vice President of Research & Development

Cell Therapy Veteran and Former Kite Pharma Clinical Leader to Head Development of Expanding Portfolio of Allogeneic CAR T Product Candidates

SOUTH SAN FRANCISCO, Calif., Jan. 03, 2023 (GLOBE NEWSWIRE) — Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer, today announced the appointment of Zachary J. Roberts M.D., Ph.D. to Executive Vice President of Research and Development. The hiring of Dr. Roberts, who previously held clinical leadership roles at Instil Bio and Kite Pharma, underscores the Company’s commitment to rapidly advancing its pipeline following recent clinical data illustrating the potential of its AlloCAR T product candidates to induce deep and durable responses. Dr. Roberts will assume the responsibilities of Rafael Amado, M.D. who has resigned to pursue other opportunities. Arun Balakumaran, M.D., Chief Medical Officer and Barbra Sasu, Ph.D., Chief Scientific Officer will report to Dr. Roberts.

“Our R&D Showcase demonstrated that we are nearing a key inflection point in the field of cell therapy. Our Phase 1 data support the opportunity to bring a first-in-class product to market with ALLO-501A for the treatment of large B cell lymphoma,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “Success in this endeavor requires a special skill set, including a relentless drive to accelerate and innovate. Having worked alongside Zach at Kite, I know Zach embodies that mindset, and I am thrilled to have him join the Allogene team as we advance multiple product candidates through development.”

Dr. Roberts is a trained immunologist and a board certified oncologist with extensive experience in clinical oncology, including the development of cell therapies. Prior to joining Allogene, Dr. Roberts was Chief Medical Officer of Instil Bio where he led development of both clinical and pre-clinical programs. Prior to that, Dr. Roberts held various roles of increasing responsibility at Kite Pharma (acquired by Gilead in 2017), where he was instrumental in the development and execution of the ZUMA trials across multiple indications for Yescarta
^®
, the first autologous CAR T therapy approved for non-Hodgkin’s lymphoma. He holds an M.D. and Ph.D. in immunology from the University of Maryland and completed clinical and post-graduate training at Massachusetts General Hospital and the Dana-Farber Cancer Institute.

“My years of experience in the field of cell therapy have convinced me that an allogeneic approach is required to deliver the full potential of CAR T to patients in need,” said Dr. Roberts. “The recent datasets presented by Allogene, including the potential to deliver deep and durable responses, have bolstered my belief and passion in this approach. I am excited to work again with some of the pioneers of cell therapy – both at Allogene and clinical trial investigators – as we bring a new treatment modality and a new hope to patients.

Dr. Chang also recognized the role played by Dr. Amado, “We appreciate Rafael’s efforts to advance pipeline candidates and validate our unique platform approach to AlloCAR T. We wish him well as he continues to pursue his passion of developing anti-cancer therapies.”

In October 2022, the Company initiated the industry’s first potentially pivotal Phase 2 allogeneic CAR T clinical trial (ALPHA2 trial) with ALLO-501A in patients with relapsed/refractory (r/r) large B cell lymphoma (LBCL). In early 2023, the Company expects to initiate the potentially pivotal Phase 2 EXPAND trial, which is intended to demonstrate the contribution of ALLO-647 to the standard fludarabine/cyclophosphamide lymphodepletion regimen, as well as advance Phase 3 readiness for a second line trial in LBCL later in the year. The Company is also planning a potentially pivotal Phase 2 trial for ALLO-715 in r/r multiple myeloma (MM), including planned regulatory discussions, optimizing the manufacturing process and transitioning manufacturing of ALLO-715 to the Company’s own manufacturing facility, Cell Forge 1. Additionally, the Company continues to enroll patients in the Phase 1 TRAVERSE trial with ALLO-316 for the treatment of advanced renal cell carcinoma.
