Dr. Michel Sadelain to Present Preclinical Data from iPSC-derived, TCR-less, CAR T-cell Collaboration at ASGCT 2018
SAN DIEGO, May 16, 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 the Company has gained access to additional intellectual property from Memorial Sloan Kettering Cancer Center (MSK) that enables the development of gene-edited T-cell immunotherapies. The newly-licensed portfolio of intellectual property covers new chimeric antigen receptor (CAR) constructs as well as off-the-shelf CAR T cells, including the use of CRISPR and other innovative technologies for their production.
Fate Therapeutics is utilizing gene editing under its ongoing collaboration for the research and development of off-the-shelf CAR T-cell immunotherapies with Michel Sadelain, M.D., Ph.D., Director of the Center for Cell Engineering and the Stephen and Barbara Friedman Chair at MSK. At the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting, Dr. Sadelain will present preclinical data on FT819, an off-the-shelf, TCR-less, CD19 CAR T-cell product manufactured from a clonal master induced pluripotent stem cell (iPSC) line.
“Engineering stem cells and using master iPSC lines for the renewable production of off-the-shelf CAR T cells has the potential to advance the cancer immunotherapy landscape,” said Dr. Sadelain. “We are pleased with the breakthrough discoveries accomplished under our ongoing collaboration with Fate Therapeutics, and look forward to continuing our advancement together of off-the-shelf CAR T-cell products toward clinical development.”
The use of clonal master iPSC lines can overcome the complexity, heterogeneity and substantial costs associated with using cells from a patient or an allogeneic donor. Instead, iPSC-derived T-cell immunotherapies can be consistently and repeatedly mass produced and delivered in an off-the-shelf manner, significantly reducing the cost of, and time to, patient treatment.
“The use of a gene-edited master iPSC line for the manufacture of off-the-shelf T-cell immunotherapies ensures complete removal of endogenous TCR expression, which is critical to avoid the life-threatening complication of graft-versus-host disease that is seen in allogeneic T-cell therapy,” said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. “The incorporation of these latest MSK technologies into our development of FT819 and our iPSC product platform advances our leadership position in developing off-the-shelf T-cell immunotherapies with improved safety, enhanced potency and expanded therapeutic reach.”
Fate Therapeutics has exclusively licensed from MSK intellectual property covering the production and composition of iPSC-derived T cells for human therapeutic use. In addition, Fate Therapeutics owns an extensive intellectual property portfolio that broadly covers compositions and methods for the genome editing of iPSCs using CRISPR and other nucleases, including the use of CRISPR to insert a CAR in the TRAC locus for endogenous transcriptional control.
FT819 is a universal, off-the-shelf, dual-targeted CAR T-cell product that is manufactured from a clonal master iPSC line. The line is engineered to completely eliminate expression of the T-cell receptor, to preferentially regulate CAR19 expression by inserting the CAR into the T-cell receptor constant (TRAC) locus, and to uniquely express a recombinant CD16 Fc receptor. In preclinical studies, FT819 exhibits a target-specific T-cell response in vitro when challenged with CD19-positive tumor cells and displays enhanced production of effector cytokines and cytolytic proteins. In addition, FT819 uniquely elicits antibody-dependent cell-mediated cytotoxicity in vitro against CD19-negative, CD20-positive tumor cells with rituximab, a monoclonal antibody targeting CD20. This dual-targeted approach of FT819 can substantially broaden the cell product’s therapeutic reach and overcome CD19 antigen escape through combination with other proven cancer treatments.
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 consistently and repeatedly manufacturing homogeneous cell products in quantities that support the treatment of many thousands of patients in a cost-effective, off-the-shelf manner. Fate Therapeutics’ iPSC product platform is supported by an intellectual property portfolio of over 90 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.
