Fate Therapeutics Secures Exclusive Option to Novel Humanized anti-BCMA CAR Constructs for Development of iPSC-derived Cell Products

Agreement with Max Delbrück Center Provides Access to Broad Intellectual Property Portfolio of Humanized Antibody Fragments and Antigen-Binding Domains Targeting BCMA

SAN DIEGO, Dec. 03, 2018 (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 today that it has secured an exclusive option to an intellectual property portfolio owned by the Max Delbrück Center for Molecular Medicine (MDC) covering novel humanized chimeric antigen receptor (CAR) constructs that uniquely and specifically bind B-cell Maturation Antigen (BCMA). Under the agreement with MDC, Fate Therapeutics holds an exclusive option to exclusively license the portfolio for all cell products, including CAR NK- and T-cell products, derived from induced pluripotent stem cells (iPSCs).

“BCMA is a validated target for cancer immunotherapy, and we are particularly impressed with the innovative work of MDC in developing superior approaches to engage BCMA with higher affinity and greater specificity,” said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. “We look forward to incorporating MDC’s humanized antigen-binding domains into our proprietary CAR constructs for NK cells and T cells, and applying our industry-leading iPSC product platform to develop universal, off-the-shelf cell products for multiple myeloma and other BCMA-positive malignancies.”

Last week, Fate Therapeutics announced that the U.S. Food and Drug Administration (FDA) has allowed its Investigational New Drug (IND) Application for FT500, the Company’s universal, off-the-shelf natural killer (NK) cell product candidate derived from a clonal master iPSC line. The clinical trial of FT500 is expected to be the first-ever clinical investigation in the U.S. of an iPSC-derived cell product. The Company’s iPSC-derived cell product platform overcomes significant challenges that limit both patient- and donor-derived cell therapy, where heterogeneous populations of primary cells are repeatedly sourced, engineered, expanded and characterized on a batch-by-batch basis resulting in cell therapies with substantial variability in quality, consistency and potency.

In a recent publication entitled “CAR T Cells with Enhanced Sensitivity to B Cell Maturation Antigen for the Targeting of B Cell Non-Hodgkin’s Lymphoma and Multiple Myeloma” (doi:10.1016/j.ymthe.2018.06.012), scientists from MDC demonstrated that anti-BCMA CAR T cells equipped with its unique humanized extracellular antigen-binding domains have higher affinity and greater specificity than other anti-BCMA antigen-binding domains. These differentiated properties provided both greater selectivity in recognizing target B cells and more robust killing of target B cells in vitro, including malignant B cells with low expression levels of BCMA. Additionally, in in vivo proof-of-concept studies, its anti-BCMA CAR T cells mediated anti-tumor activity in xenotransplant mouse models of multiple myeloma as well as mature B-cell non-Hodgkin lymphoma, where BCMA surface expression is up to 4-fold lower as compared to multiple myeloma cells.

Fate Therapeutics is applying its iPSC product platform, which utilizes clonal master engineered iPSC lines to mass produce NK- and T-cell products that are uniformly engineered and extensively characterized, to create off-the-shelf cell-based cancer immunotherapies for multiple myeloma. The intellectual property of MDC covered under the exclusive option includes humanized antibody fragments that bind a unique BCMA epitope, humanized CAR constructs with extracellular antigen-binding domains to BCMA, and immune cells, including NK cells and T cells, expressing anti-BCMA CAR constructs.

About Fate Therapeutics’ iPSC Product Platform
The Company’s proprietary iPSC product platform enables mass production of off-the-shelf, engineered, homogeneous cell products that can be administered in repeat doses to mediate more effective pharmacologic activity, including in combination with cycles of other cancer treatments. Human iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The Company’s first-of-kind approach involves engineering human iPSCs in a one-time genetic modification event, and selecting a single iPSC for maintenance as a clonal master iPSC line. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, clonal master iPSC lines are a renewable source for manufacturing cell therapy products which are well-defined and uniform in composition, can be mass produced at significant scale in a cost-effective manner, and can be delivered off-the-shelf to treat many patients. Fate Therapeutics’ iPSC product platform is supported by an intellectual property portfolio of over 100 issued patents and 100 pending patent applications.             

About Fate Therapeutics, Inc.
Fate Therapeutics is a clinical-stage biopharmaceutical company dedicated to the development of first-in-class cellular immunotherapies for cancer and immune disorders. The Company is pioneering the development of off-the-shelf cell products using its proprietary induced pluripotent stem cell (iPSC) product platform. The Company’s immuno-oncology pipeline is comprised of FATE-NK100, a donor-derived natural killer (NK) cell cancer immunotherapy that is currently being evaluated in three Phase 1 clinical trials, as well as iPSC-derived NK cell and T-cell immunotherapies, with a focus on developing augmented cell products intended to synergize with checkpoint inhibitor and monoclonal antibody therapies and to target tumor-specific antigens. The Company’s immuno-regulatory pipeline includes ProTmune™, a next-generation donor cell graft that is currently being evaluated in a Phase 2 clinical trial for the prevention of graft-versus-host disease, and a myeloid-derived suppressor cell immunotherapy for promoting immune tolerance in patients with immune disorders. Fate Therapeutics is headquartered in San Diego, CA. For more information, please visit www.fatetherapeutics.com.
