Allogene Therapeutics Showcases Momentum with Clinical and Platform Advancements in Allogeneic CAR T at AACR 2026

SOUTH SAN FRANCISCO, Calif., April 20, 2026 (GLOBE NEWSWIRE) — Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T) products, today announced upcoming presentations at the American Association for Cancer Research (AACR) Annual Meeting, April 17-22, 2026, in San Diego, Calif.

Allogene’s presentations at AACR highlight the potential of allogeneic CAR T to expand access, simplify delivery, and enable broader application of cell therapy across diseases when its inherent advantages are fully leveraged. The Company will participate in several AACR 2026 scientific forums, including:

Poster: Preclinical Evaluation of Allogeneic BCMA/CD70 Dual CAR T Cells for High-Risk Multiple Myeloma
Presenter: Mark K. O’Dair, PhD, Allogene
Session Title: CAR T Cell Targets and TME Reprogramming
Poster Number: 1535
Location: Poster Section 7, Board 17
Session Date and Time: Monday, April 20, 9:00am-12:00pm PT

Based on its foundational work in oncology, Allogene is extending its Dagger^® technology into autoimmune disease, applying its gene-edited, dual-targeting CAR T approach to target both BCMA and CD70 on malignant plasma cells as well as selectively eliminate alloreactive immune cells to promote durable persistence with reduced need for chemotherapy-based lymphodepletion. This strategy builds on the Company’s expertise in allogeneic cell therapy in advanced renal cell carcinoma and is designed to deliver a readily available, off-the-shelf treatment with the potential to transform how both cancer and autoimmune diseases are treated.

Major Symposium: Off-the-Shelf Cell Therapies for Cancer and Beyond
Presenter: David Chang, M.D., Ph.D., President, CEO and Co-Founder, Allogene Therapeutics
Title: Allogeneic CAR-T: Science at Scale (SY13-03)
Location: Room 28 – Upper Level – Convention Center
Session Date and Time: Tuesday, April 21, 12:30-2:00pm PT

The future of CAR T will be defined by its ability to reach more patients, more reliably and earlier in the course of disease. Allogene’s allogeneic approach is designed to unlock this potential across five key dimensions: speed, with on-demand availability; safety, manageable across care settings; simplicity, as a one-time outpatient treatment; scalability, enabling broad patient access; and survival, with the potential to deliver meaningful clinical outcomes. Together, these attributes represent a path toward making CAR T a more practical and widely accessible therapy.

Forum: Cell Therapy at a Crossroads: Exploring the Evolving Landscape between Autologous, Allogeneic, and In Vivo Engineering (Session: FO06)
Presenter: Zachary Roberts, M.D., Ph.D., EVP, Research and Development, CMO, Allogene Therapeutics
Location: Ballroom 20 AB – Upper Level – Convention Center
Session Date and Time: Tuesday, April 21, 5:00pm-6:30pm PT

Allogeneic CAR T therapy represents a major step forward in the evolution from autologous products. With extensive experience across both hematologic and solid tumors, Allogene has been a singular leader since the earliest days of allogeneic cell therapy and has defined a path through many of the scientific challenges the field has faced. As key trials advance Allogene is positioning allogeneic CAR T as a bridge to biologic-like manufacturing scale necessary to address an ever-growing patient demand for these life-saving products.
