Fate Therapeutics Announces New Preclinical Data for FT596 Off-the-Shelf, iPSC-derived CAR NK Cell Cancer Immunotherapy

FT596 as a Monotherapy Demonstrates Comparable Anti-tumor Activity to CAR19 T Cells In Vivo in Humanized Mouse Model of Lymphoma

Combination of FT596 with Rituximab Shows Durable Tumor Clearance In Vivo in Preclinical Lymphoma Model

Company Plans to Initiate Enrollment of First-in-human Clinical Trial of FT596 in Early 2020

SAN DIEGO, Dec. 08, 2019 (GLOBE NEWSWIRE) -- Fate Therapeutics, Inc. (NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for cancer and immune disorders, announced new in vivo preclinical data for FT596, its off-the-shelf, multi-antigen targeting natural killer (NK) cell product candidate derived from a clonal master engineered induced pluripotent stem cell (iPSC) line. The data were featured during the 61^st American Society of Hematology (ASH) Meeting and Exposition as part of the organization’s CAR-T and Beyond press program, which spotlighted promising next-generation cancer immunotherapies having the potential to overcome the key limitations of patient-specific chimeric antigen receptor (CAR) T-cell therapy.

“Current patient- and donor-specific CAR T-cell immunotherapies recognize only one antigen and fail to address the significant risk of relapse due to antigen escape. FT596 is ground-breaking in that it is designed to be available off-the-shelf for timely patient access and to promote deeper and more durable responses by targeting multiple tumor-associated antigens,” said Bob Valamehr, Ph.D., Chief Development Officer of Fate Therapeutics. “Additionally, since FT596 is manufactured from a renewable master engineered iPSC line, the complexities of patient-by-patient genetic engineering and production are greatly reduced and, for the first time, we are able to mass produce multi-functional cellular immunotherapies in a uniform and cost-effective manner.”

FT596 is the first cellular immunotherapy engineered with three active anti-tumor components to be cleared for clinical investigation by the FDA. In addition to a proprietary CAR targeting CD19, FT596 expresses a novel high-affinity, non-cleavable CD16 (hnCD16) Fc receptor that has been modified to augment antibody-dependent cellular cytotoxicity, enabling coincident targeting of CD19 and additional tumor-associated antigens such as CD20. FT596 also expresses an interleukin-15 receptor fusion (IL-15RF), a potent cytokine complex that promotes survival, proliferation and trans-activation of NK cells and CD8 T cells without the need for systemic cytokine support. Together, these features of FT596 are intended to maximize potency and minimize toxicity in treated patients. The Company plans to initiate enrollment of a first-in-human clinical trial of FT596 in early 2020.
