Ended Quarter with $533 Million in Cash & Short-term Investments

SAN DIEGO, Aug. 05, 2020 (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 second quarter ended June 30, 2020.

“Early clinical data from our FT596 program are very encouraging, as we observed a partial response in a heavily-pretreated patient with refractory diffuse large B-cell lymphoma at the first dose level without any reported events of cytokine release syndrome, neurotoxicity or graft-versus-host disease. Additionally, the safety, tolerability, and immunogenicity data across our off-the-shelf NK cell programs continue to suggest that multiple doses of iPSC-derived NK cells can be administered to a patient without matching,” said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. “We continue to be pleased with our pace of innovation, where the recent clearances of our IND applications by the FDA for FT538, the first-ever CRISPR-edited iPSC-derived cell therapy, and for FT819, the first-ever iPSC-derived CAR T-cell therapy, continue to demonstrate our unique ability to rapidly bring multiplexed engineered, off-the-shelf NK cell and T-cell cancer immunotherapies to patients. In addition, we successfully launched our Janssen collaboration with strong momentum, bringing together Janssen’s proprietary tumor-targeting antigen binders and our industry-leading iPSC product platform to develop novel off-the-shelf CAR NK and CAR T-cell immunotherapies for hematologic malignancies and solid tumors.”

Clinical Programs

• Partial Response Reported with FT596 Monotherapy at First Dose Level. In June, the Company reported Day 29 protocol-defined response assessments for the first two patients treated with FT596, the Company’s off-the-shelf natural killer (NK) cell product candidate derived from a clonal master induced pluripotent stem cell (iPSC) line engineered with three anti-cancer modalities: a proprietary CD19-targeting chimeric antigen receptor (CAR), a novel high-affinity, non-cleavable CD16 (hnCD16) Fc receptor, and an IL-15/IL-15 receptor fusion. Each patient had previously been treated with at least four lines of therapy for diffuse large B-cell lymphoma (DLBCL), and was administered a single dose of FT596 as a monotherapy at the first dose level (30 million cells). The first patient had progressive disease, having most recently relapsed following treatment with an FDA-approved CD19-targeting CAR T-cell therapy. The second patient had a partial response, having most recently been refractory to an experimental donor-derived NK cell regimen. The FT596 response assessment in this patient showed a greater than 70% reduction in metabolic activity and a greater than 50% reduction in tumor size as assessed by PET-CT scan. No dose-limiting toxicities, no FT596-related serious adverse events (SAEs), and no events of cytokine release syndrome, neurotoxicity, or graft-versus-host disease were reported by investigators in either patient.
• Enrollment Initiated with FT596 in Combination with Rituximab for B-cell Lymphoma. In addition to assessing FT596 as a monotherapy, the FT596 Phase 1 clinical trial includes the administration of FT596 in combination with rituximab, which enables dual-antigen targeting of CD19 and CD20 through the product candidate’s CAR and hnCD16 receptors, respectively. Enrollment into this dose-escalating regimen has been initiated at 30 million cells for patients with relapsed / refractory B-cell lymphoma.
• Second FT516 IND Application Cleared by FDA for Advanced Solid Tumors. In April, the U.S. Food & Drug Administration (FDA) cleared an investigational new drug (IND) application for FT516, the Company’s off-the-shelf NK cell cancer immunotherapy derived from a clonal master iPSC line engineered to express hnCD16 Fc receptor. The Phase 1 study, which is sponsored by investigators from the Masonic Cancer Center, University of Minnesota, is intended to assess intraperitoneal administration of three once-weekly doses of FT516, each with IL-2 cytokine support, for women with recurrent ovarian cancer. The Company is preparing to initiate a multi-dose Phase 1 clinical trial of FT516 in combination with avelumab, a checkpoint inhibitor therapy targeting PD-L1, for patients with advanced solid tumors, and is continuing to enroll a multi-dose Phase 1 clinical trial of FT516 as a monotherapy for patients with acute myeloid leukemia (AML) and in combination with CD20-directed monoclonal antibodies for patients with advanced B-cell lymphoma.
• Evidence of Clinical Activity Observed with FT500 for Advanced Solid Tumors. In May 2020, the Company announced the completion of the dose-escalation stage of the FT500 Phase 1 clinical trial for advanced solid tumors, having enrolled three patients at the second dose level of FT500 in combination with checkpoint inhibitor therapy. Each of these three patients was previously treated with at least four lines of therapy, and most recently was refractory to, or had relapsed on, checkpoint inhibitor therapy. Evidence of clinical activity was observed in two patients, with one patient having a 58% reduction in the size of target lesions prior to discontinuing treatment during the second 30-day cycle due to non-target lesion formation and one patient having stable disease following completion of the second 30-day cycle. No dose-limiting toxicities, no FT500-related SAEs or Grade ≥3 adverse events, and no events of cytokine release syndrome, neurotoxicity, or graft-versus-host disease were reported by investigators in the dose-escalation stage of the study. The Company is enrolling the dose-expansion stage of the FT500 Phase 1 clinical trial and intends to treat up to 15 patients who are refractory to, or have relapsed on, checkpoint inhibitor therapy, administering three once-weekly doses of FT500 at 300 million cells per dose, each with IL-2 cytokine support, for up to two 30-day cycles in combination with the same checkpoint inhibitor on which the patient failed or relapsed.
• IND Application Cleared by FDA for FT538, the First-ever CRISPR-edited, iPSC-derived Cell Therapy. In May 2020, the FDA cleared the Company’s IND application for FT538, its off-the-shelf NK cell product candidate derived from a clonal master iPSC line engineered with three functional components to enhance innate immunity: a novel hnCD16 Fc receptor; an IL-15/IL-15 receptor fusion; and the elimination of CD38 expression. The Company is preparing to initiate a multi-center Phase 1 clinical trial of three once-weekly doses of FT538 as a monotherapy for patients with relapsed / refractory AML and in combination with daratumumab for patients with relapsed / refractory multiple myeloma.
• IND Application Cleared by FDA for FT819, the First-ever iPSC-derived CAR T-cell Therapy. In June 2020, the FDA cleared the Company’s IND application for FT819, an off-the-shelf allogeneic CAR T-cell therapy targeting CD19+ malignancies. FT819 is the first-ever CAR T-cell therapy derived from a clonal master iPSC line, and is engineered with several first-of-kind features designed to improve the safety and efficacy of CAR T-cell therapy including: a novel 1XX CAR signaling domain, which has been shown to extend T-cell effector function without eliciting exhaustion; integration of the CAR transgene directly into the T-cell receptor alpha constant (TRAC) locus, which has been shown to promote uniform CAR expression and enhanced T-cell potency; and complete bi-allelic disruption of T-cell receptor expression for the prevention of graft-versus-host disease, a potentially life-threatening complication associated with allogeneic T-cell therapy. The Company is preparing to initiate a multi-center Phase 1 clinical trial of FT819 for patients with chronic lymphocytic leukemia, acute lymphoblastic leukemia, or B-cell lymphoma. Each indication will enroll independently and evaluate three dose-escalating treatment regimens: a single dose of FT819; a single dose of FT819 with IL-2 cytokine support; and three fractionated doses of FT819.
• Investigator-initiated Clinical Trial of FT516 for COVID-19 Opened to Enrollment. Investigators from the Department of Medicine, Division of Infectious Diseases and International Medicine, University of Minnesota are currently enrolling a Phase 1 clinical trial of FT516 in up to 20 patients with Coronavirus Disease 2019 (COVID-19) at high risk of developing critical life-threatening illness.

Preclinical Programs

• Four Anti-Tumor Modalities of FT576 for Multiple Myeloma Highlighted at ASGCT. The Company presented new preclinical data for FT576, its off-the-shelf, iPSC-derived, multi-antigen targeted CAR-BCMA NK cell product candidate for multiple myeloma, at the American Society of Gene & Cell Therapy (ASGCT) Virtual Annual Meeting in May. In a serial re-stimulation cytotoxicity assay against an MM1.R myeloma cell line, FT576 was shown to be resistant to anti-CD38 monoclonal antibody induced fratricide and to have enhanced cytotoxicity both as a monotherapy and in combination with daratumumab as compared to daratumumab alone. The presentation “Generation of a Novel Single Cell-Derived Multi-Engineered Master Pluripotent Cell Line as a Renewable Source of Off-The-Shelf Multi-Antigen-Targeting NK Cell Immunotherapy for Multiple Myeloma” was selected by ASGCT as an outstanding poster award winner.
• New CAR MICA/B Solid Tumor Program Announced. At ASGCT in May, the Company presented initial preclinical data from its new CAR MICA/B solid tumor program, which targets the pan-tumor associated stress antigens MICA and MICB. While these stress-inducible cell-surface proteins are selectively expressed at high levels on many solid tumors, shedding of these proteins by cancer cells is a common mechanism of immune evasion. The preclinical data demonstrated that the Company’s novel CAR MICA/B construct targets a specific epitope that uniquely prevents antigen shedding to overcome tumor escape (Science, DOI: 10.1126/science.aao0505).

Corporate Highlights

• Strategic Collaboration Formed with Janssen for Novel iPSC-derived Cell-based Cancer Immunotherapies. In April, the Company entered into a global collaboration and option agreement with Janssen Biotech, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, to develop iPSC-derived CAR NK and CAR T-cell product candidates targeting up to four tumor-associated antigens. In entering into the collaboration, the Company received $100 million including $50 million in an upfront cash payment and $50 million from the purchase by Johnson & Johnson Innovation – JJDC, Inc. (JJDC) of the Company’s common stock. The Company is eligible to receive payments of up to $3.0 billion upon the achievement of certain development, regulatory and commercial milestones, plus tiered double-digit royalties on worldwide net sales of products targeting the antigens, and has the right to elect to co-commercialize each product candidate in the U.S. and share equally in profits and losses in the U.S., subject to its payment of certain clinical development costs and adjustments in milestone and royalty payments.
• Completed $201 Million Common Stock Offering. In June, the Company closed an underwritten public offering of 7.1 million shares of its common stock at a public offering price of $28.31 per share. In connection with the offering, JJDC purchased an additional 1.8 million newly-issued shares of the Company’s common stock in a private placement at the offering price.

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 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 Company’s 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 Company’s 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 300 issued patents and 150 pending patent applications.

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. The product candidate is being investigated in an open-label, multi-dose Phase 1 clinical trial for the treatment of advanced solid tumors (NCT03841110). The study is designed to assess the safety and tolerability 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 their disease progresses 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 FT516
FT516 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 (hnCD16) Fc receptor, which has been modified to prevent its down-regulation and to enhance its binding to tumor-targeting antibodies. CD16 mediates antibody-dependent cellular cytotoxicity (ADCC), a potent anti-tumor mechanism by which NK cells recognize, bind and kill antibody-coated cancer cells. ADCC is dependent on NK cells maintaining stable and effective expression of CD16, which has been shown to undergo considerable down-regulation in cancer patients. In addition, CD16 occurs in two variants, 158V or 158F, that elicit high or low binding affinity, respectively, to 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. FT516 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 (NCT04023071). Additionally, the FDA has allowed investigation of FT516 in an open-label, multi-dose Phase 1 clinical trial in combination with monoclonal antibody therapy, including PDL1-, PD1-, EGFR- and HER2-targeting therapeutic antibodies, across a broad range of solid tumors.

About FT596
FT596 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 that targets B-cell antigen CD19; a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor, which has been modified to prevent its down-regulation and to enhance its binding to tumor-targeting antibodies; and an IL-15 receptor fusion (IL-15RF) that promotes enhanced NK cell activity. In preclinical studies of FT596, the Company has demonstrated that dual activation of the CAR19 and hnCD16 targeting receptors enhances cytotoxic activity, indicating that multi-antigen engagement may elicit a deeper and more durable response. Additionally, in a humanized mouse model of lymphoma, FT596 in combination with the anti-CD20 monoclonal antibody rituximab showed enhanced killing of tumor cells in vivo as compared to rituximab alone. FT596 is being investigated in an open-label, multi-center Phase 1 clinical trial for the treatment of relapsed / refractory B-cell malignancies (NCT04245722). The FT596 Phase 1 clinical trial includes three treatment regimens: Regimen A as a monotherapy for patients with relapsed / refractory B-cell lymphoma; Regimen B1 in combination with rituximab for patients with relapsed / refractory B-cell lymphoma who have previously failed or progressed on rituximab; and Regimen B2 in combination with obinutuzumab for patients with relapsed / refractory chronic lymphocytic leukemia (CLL).
