$303 Million in Cash & Short-term Investments as of September 30, 2019 following Completion of $173 Million Common Stock Offering

SAN DIEGO, Nov. 05, 2019 (GLOBE NEWSWIRE) -- Fate Therapeutics, Inc. (FATE), a clinical-stage biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for cancer and immune disorders, today reported business highlights and financial results for the third quarter ended September 30, 2019.

We achieved several significant clinical milestones over the past three months including treating the first patients with FT516, the first-ever engineered iPSC-derived cellular immunotherapy, and securing FDA clearance to initiate clinical investigation of FT596, the first-ever cellular immunotherapy engineered to express three active anti-tumor modalities. We also successfully opened our new cGMP facility specifically designed to enable consistent, large-scale, and cost-effective manufacture of allogeneic NK cell and CAR-T cell products using clonal master iPSC lines as a starting cell source, said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. We look forward to the ASH annual meeting in December, where we have had six abstracts accepted and will be sharing our first-in-human insights into the clinical safety and tolerability of FT500, the first-ever iPSC-derived cell therapy to be administered off-the-shelf in multiple doses over multiple cycles. With the completion of our recent common stock offering in September, we are well-positioned to generate clinical data across our iPSC-derived, cell-based cancer immunotherapy pipeline in 2020.

Third Quarter 2019 Financial Results

Today's Conference Call and WebcastThe Company will conduct a conference call today, Tuesday, November 5, 2019 at 5:00 p.m. ET to review financial and operating results for the quarter ended September 30, 2019. In order to participate in the conference call, please dial 877-303-6235 (domestic) or 631-291-4837 (international) and refer to conference ID 4748666. The live webcast can be accessed under "Events & Presentations" in the Investors & Media section of the Company's website at http://www.fatetherapeutics.com. The archived webcast will be available on the Company's website beginning approximately two hours after the event.

About Fate Therapeutics iPSC Product PlatformThe Companys proprietary induced pluripotent stem cell (iPSC) product platform enables mass production of off-the-shelf, engineered, homogeneous cell products that can be administered with multiple doses to deliver 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 Companys first-of-kind approach involves engineering human iPSCs in a one-time genetic modification event and selecting a single engineered 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 for patient treatment. As a result, the Companys platform is uniquely capable of overcoming numerous limitations associated with the production of cell therapies using patient- or donor-sourced cells, which is logistically complex and expensive and is subject to batch-to-batch and cell-to-cell variability that can affect clinical safety and efficacy. Fate Therapeutics iPSC product platform is supported by an intellectual property portfolio of over 250 issued patents and 150 pending patent applications.

Story continues

About FT500FT500 is an investigational, universal, off-the-shelf natural killer (NK) cell cancer immunotherapy derived from a clonal master induced pluripotent stem cell (iPSC) line. The product candidate is being investigated in an open-label, multi-dose Phase 1 clinical trial for the treatment of advanced solid tumors (clinicaltrials.gov ID number NCT03841110). The study is designed to assess the safety and activity of three once-weekly doses of FT500 as a monotherapy and in combination with one of three FDA-approved immune checkpoint inhibitor (ICI) therapies nivolumab, pembrolizumab or atezolizumab in patients that have failed prior ICI therapy. Despite the clinical benefit conferred by approved ICI therapy against a variety of tumor types, these therapies are not curative and, in most cases, patients either fail to respond or progress on these agents. One common mechanism of resistance to ICI therapy is associated with loss-of-function mutations in genes critical for antigen presentation. A potential strategy to overcome resistance is through the administration of allogeneic NK cells, which have the inherent capability to recognize and directly kill tumor cells with these mutations.

About FT516FT516 is an investigational, universal, off-the-shelf natural killer (NK) cell cancer immunotherapy derived from a clonal master induced pluripotent stem cell (iPSC) line engineered to express a novel high-affinity 158V, non-cleavable CD16 Fc receptor, which has been modified to prevent its down-regulation and enhance its binding to tumor-targeting antibodies. The product candidate is being investigated in an open-label, multi-dose Phase 1 clinical trial as a monotherapy for the treatment of acute myeloid leukemia and in combination with CD20-directed monoclonal antibodies for the treatment of advanced B-cell lymphoma (clinicaltrials.gov ID number NCT04023071). CD16 mediates antibody-dependent cellular cytotoxicity (ADCC), a potent anti-tumor mechanism by which NK cells recognize, bind and kill antibody-coated cancer cells. CD16 occurs in two variants, either with high (158V) or low (158F) affinity for the Fc domain of IgG1 antibodies. Numerous clinical studies with FDA-approved tumor-targeting antibodies, including rituximab, trastuzumab and cetuximab, have demonstrated that patients homozygous for the 158V variant, which is present in only about 15% of patients, have improved clinical outcomes. In addition, ADCC is dependent on NK cells maintaining active levels of CD16 expression, and the expression of CD16 on NK cells has been shown to undergo considerable down-regulation in cancer patients, which can significantly inhibit anti-tumor activity.

About FT596FT596 is an investigational, universal, off-the-shelf natural killer (NK) cell cancer immunotherapy derived from a clonal master induced pluripotent stem cell (iPSC) line engineered with three anti-tumor functional modalities: a proprietary chimeric antigen receptor (CAR) optimized for NK cell biology, which contains a NKG2D transmembrane domain, a 2B4 co-stimulatory domain and a CD3-zeta signaling domain, that targets B-cell antigen CD19; a novel high-affinity 158V, non-cleavable CD16 Fc receptor that has been modified to augment antibody-dependent cellular cytotoxicity by preventing CD16 down-regulation and enhancing CD16 binding to tumor-targeting antibodies; and an IL-15 receptor fusion (IL-15RF) that promotes enhanced NK cell activity. The FDA has allowed investigation of FT596 in an open-label Phase 1 clinical trial as a monotherapy, in combination with rituximab for the treatment of advanced B-cell lymphoma, and in combination with obinutuzumab for the treatment of chronic lymphocytic leukemia. In preclinical studies of FT596, the Company has demonstrated that dual activation of the CAR19 and CD16 receptors, in combination with IL-15RF signaling, convey synergistic anti-tumor activity. Increased degranulation and cytokine release were observed upon dual receptor activation in lymphoma cancer cells as compared to activation of each receptor alone, indicating that multi-antigen engagement may elicit a deeper and more durable response. Additionally, in a mixed cellular composition cytotoxicity assay comprised of CD19+ and CD19- tumor cells, FT596 combined with CD20-directed monoclonal antibody therapy effectively eliminated the heterogeneous population of tumor cells, a result that was not observed with single-antigen targeted CAR19 T cells.
