Marks First-ever Human Administration of iPSC-derived Cell Therapy in the United States

$201 Million in Cash & Short-term Investments as of December 31, 2018

SAN DIEGO, March 05, 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, today reported business highlights and financial results for the fourth quarter and year ended December 31, 2018.

“We achieved an unprecedented milestone in treating the first patient with FT500, which is the first-ever administration of an iPSC-derived cell therapy to a patient in the U.S. In 2018, we made great strides toward our vision of using master iPSC lines to produce universal, off-the-shelf cell-based cancer immunotherapies that are available ‘on demand’ and deliver transformational change in patient outcomes,” said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. “The year was also highlighted by strong clinical execution and encouraging patient data for our ongoing allogeneic cell therapy programs, ProTmune and FATE-NK100. Additionally, our industry-leading iPSC product platform delivered multiple highly differentiated, off-the-shelf NK cell and T-cell product candidates, which we expect to move into the clinic in 2019.”

Clinical Programs

• First-ever iPSC-derived Cell Product FT500 Administered to a Patient in the U.S. In November 2018, the U.S. Food and Drug Administration (FDA) cleared the Company’s Investigational New Drug (IND) application for FT500, a universal, off-the-shelf natural killer (NK) cell product candidate derived from a clonal master induced pluripotent stem cell (iPSC) line. The landmark clinical trial is intended to assess the safety and efficacy of multiple doses of FT500 over multiple dosing cycles for the treatment of advanced solid tumors as a monotherapy and as a combination with nivolumab, pembrolizumab or atezolizumab in patients that failed to respond to, or progressed on, checkpoint inhibitor therapy. The first subject was treated with FT500 in February 2019.
• Anti-Tumor Activity of FATE-NK100 Observed Across Three Phase 1 Studies. In November 2018, the Company reported initial dose-escalation clinical data of FATE-NK100 from fifteen subjects across three Phase 1 clinical trials for the treatment of relapsed / refractory acute myelogenous leukemia, recurrent ovarian cancer and advanced solid tumors. As of an October 22, 2018 data cutoff, no FATE-NK100-related dose limiting toxicities were reported, and anti-tumor activity was observed with a single dose of FATE-NK100 in seven of the fifteen subjects. Three of these seven subjects were subsequently treated with a second dose of FATE-NK100, which was well-tolerated and showed persistence. All three of these subjects achieved durable disease control for at least three months, providing initial proof-of-concept for multi-dose administration of donor NK cell therapy.
• Presented One-Year Follow-up Data from Phase 1 PROTECT Study of ProTmune™. At the 2018 American Society of Hematology (ASH) Annual Meeting, the Company released new clinical data from the seven subjects receiving ProTmune for the treatment of hematologic malignancies in the Phase 1 stage of the PROTECT study. As of a November 26, 2018 data cutoff with a median time on study of 516 days [range 151-616], there were no ProTmune-related SAEs reported by investigators, no events of graft failure and no events of leukemia relapse, and five of seven subjects remained alive and leukemia-free (71%). Additionally, three of seven subjects (43%) successfully met a novel composite endpoint of freedom from moderate-to-severe chronic graft-versus-host disease (GvHD), leukemia relapse and death at one year, which endpoint is intended to measure the overall effectiveness of allogeneic HCT. The Company expects to complete enrollment of the randomized, controlled and double-blind Phase 2 PROTECT study in 2019, and that data on the primary and secondary endpoints will be available in 2020.

Universal Off-the-Shelf NK and T-cell Cancer Immunotherapy Preclinical Pipeline

• Received FDA Clearance of IND Application for First-ever Engineered iPSC-derived Cell Product FT516. In January 2019, the Company submitted an IND application to the FDA for FT516, a universal, off-the-shelf NK cell product candidate derived from a clonal master iPSC line engineered to express a novel high-affinity, non-cleavable CD16 (hnCD16) Fc receptor. CD16 mediates antibody-dependent cellular cytotoxicity (ADCC), a potent anti-tumor mechanism by which NK cells recognize, bind and kill antibody-coated cancer cells. Numerous clinical studies with FDA-approved tumor-targeting antibodies have demonstrated that patients with the CD16 high-affinity variant (158V) have improved clinical outcomes. The Company announced in February 2019 that the FDA allowed its FT516 IND application for the treatment of relapsed / refractory hematologic malignancies including in combination with certain FDA-approved monoclonal antibody therapies. FT516 is the first-ever cell product derived from a genetically engineered pluripotent stem cell cleared for clinical testing worldwide.
• Presented FT596 Preclinical Data of Dual Antigen-Specific Targeting. FT596 is the Company’s universal, off-the-shelf chimeric antigen receptor (CAR) NK cell product candidate that expresses a proprietary CD19-targeted CAR, a hnCD16 Fc receptor for augmented ADCC and a novel IL-15 receptor fusion for cytokine-independent persistence. A presentation at ASH by scientists from the Company and the University of California – San Diego highlighted new in vivo data demonstrating that FT596 displays enhanced persistence and promotes long-term survival in a B-cell leukemia xenograft model. Moreover, as proof-of-concept for dual antigen-specific targeting and the mitigation of antigen escape, FT596 in combination with rituximab completely eliminated CD19+ and CD19- tumor cells in a co-culture cellular cytotoxicity assay. The Company expects to submit an IND application to the FDA in mid-2019 for clinical investigation of FT596.
• Presented In Vivo Preclinical Data from Off-the-Shelf, iPSC-derived CAR T-cell Program. A presentation at ASH by scientists from the Company and Memorial Sloan Kettering Cancer Center (MSK) showcased new in vivo data demonstrating that the control of tumor progression with FT819, the Company’s off-the-shelf, TCR-less, CD19-targeted CAR T-cell product candidate manufactured from a clonal master iPSC, is comparable to that with peripheral blood CAR T cells in a preclinical mouse model of acute lymphoblastic leukemia. The clonal master iPSC line includes the targeted integration of a novel 1XX CAR into the T-cell receptor α constant (TRAC) locus, which is intended to regulate CAR expression for enhanced safety and efficacy and completely eliminate T-cell receptor (TCR) expression to mitigate GvHD. FT819 is being co-developed under a collaboration with MSK led by Dr. Michel Sadelain.

Corporate Highlights

• In-licensed Novel Humanized anti-BCMA CAR Constructs. In December 2018, the Company announced that it had entered into an agreement with the Max Delbrück Center (MDC) for exclusive access to a broad intellectual property portfolio of humanized antibody fragments, antigen-binding domains and CAR constructs that uniquely target and specifically bind B-cell Maturation Antigen (BCMA). 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 both greater selectivity and sensitivity in recognizing, and more robust killing of, target B cells in vitro as compared to other anti-BCMA antigen-binding domains.
• Initiated Build-out of In-house GMP Manufacturing. In January 2019, the Company expanded its corporate headquarters in San Diego to include state-of-the art GMP manufacturing facilities for the clinical supply of its off-the-shelf, iPSC-derived cell product candidates. The modular design is customized to support the mass production of multiple product candidates in parallel. The Company expects to initiate in-house GMP manufacture of its off-the-shelf, iPSC-derived cell product candidates in the second half of 2019.

About ProTmune™
ProTmune™ is an investigational, first-in-class, allogeneic hematopoietic cell graft for the prevention of acute graft-versus-host disease (GvHD) in patients undergoing hematopoietic cell transplantation (HCT) for the treatment of hematologic malignancies. ProTmune is manufactured by pharmacologically modulating a donor-sourced, mobilized peripheral blood graft ex vivo with two small molecules (FT1050 and FT4145) to decrease the incidence and severity of acute GvHD while maintaining the anti-leukemia activity of the graft. ProTmune has been granted Orphan Drug and Fast Track Designations by the U.S. Food and Drug Administration, and Orphan Medicinal Product Designation by the European Commission. ProTmune is currently being investigated in a randomized, controlled and double-blind Phase 2 clinical trial in adult subjects with hematologic malignancies undergoing matched unrelated donor HCT.

About FATE-NK100
FATE-NK100 is an investigational, first-in-class, allogeneic donor-derived natural killer (NK) cell cancer immunotherapy comprised of adaptive memory NK cells, a highly specialized and functionally distinct subset of activated NK cells expressing the maturation marker CD57. Higher frequencies of CD57⁺ NK cells in the peripheral blood or tumor microenvironment in cancer patients have been linked to better clinical outcomes. In August 2017, non-clinical data describing the unique properties and anti-tumor activity of FATE-NK100 were published by Cancer Research (doi:10.1158/0008-5472.CAN-17-0799), a peer-reviewed journal of the American Association of Cancer Research. Three clinical trials of FATE-NK100 are currently being conducted: VOYAGE for the treatment of refractory or relapsed acute myelogenous leukemia; APOLLO for the treatment of recurrent ovarian cancer; and DIMENSION for the treatment of advanced solid tumors, including in combination with monoclonal antibody therapy.

About FT500
FT500 is an investigational, universal, off-the-shelf natural killer (NK) cell cancer immunotherapy derived from a clonal master induced pluripotent stem cell (iPSC) line. FT500 is being investigated in an open-label, repeat-dose Phase 1 clinical trial for the treatment of advanced solid tumors in up to 64 subjects, both as a monotherapy and in combination with FDA-approved checkpoint inhibitor therapy. Despite the favorable response rates observed with checkpoint inhibitor therapy, the majority of patients do not respond and many responders relapse. One common mechanism of resistance to checkpoint inhibitor 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 Fate Therapeutics’ iPSC Product Platform
The Company’s proprietary induced pluripotent stem cell (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. As a result, the Company’s platform is uniquely capable of addressing the limitations associated with the production of cell therapies using patient- or donor-sourced cells, which is logistically complex and expensive and is fraught with batch-to-batch and cell-to-cell variability that can affect safety and efficacy. Fate Therapeutics’ iPSC product platform is supported by an intellectual property portfolio of over 100 issued patents and 100 pending patent applications.
