Non-Clinical Studies Demonstrate Unique Anti-tumor Activity of Natural Killer Cell Product Candidate
FDA Clears IND for FATE-NK100 in Ovarian Cancer
SAN DIEGO, Aug. 08, 2017 (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 peer-reviewed publication of non-clinical data describing the unique properties and anti-tumor activity of FATE-NK100, the Company’s first-in-class adaptive memory natural killer (NK) cell product candidate. Additionally, the Company announced that the U.S. Food and Drug Administration (FDA) has cleared a third investigational new drug (IND) application for FATE-NK100, with the most recent clearance authorizing the study of FATE-NK100 in women with ovarian cancer resistant to, or recurrent on, platinum-based treatment.
The findings published online by Cancer Research (doi:10.1158/0008-5472.CAN-17-0799), a peer-reviewed journal of the American Association of Cancer Research, are the first demonstration of a GMP-compatible manufacturing process that induces both NK cell expansion and acquisition of CD57, a marker of NK cell maturation. Higher frequencies of CD57+ NK cells in the peripheral blood or tumor microenvironment in cancer patients have been linked to better clinical outcomes. FATE-NK100 is comprised of adaptive memory NK cells expressing CD57 and the memory-like activating receptor NKG2C.
“Our ability to successfully and reproducibly manufacture FATE-NK100 enables, for the first time, the administration of therapeutic quantities of mature, highly cytotoxic NK cells to patients for the treatment of cancer. Multiple studies point to a distinct role for CD57+ NK cells in cancer immune-surveillance, where the acquisition of CD57 on NK cells is associated with a profound shift towards enhanced effector function and potency,” said Scott Wolchko, President and Chief Executive Officer of Fate Therapeutics. “We look forward to initiating a third clinical trial of FATE-NK100 in advanced malignancies, and are excited to see early clinical results from each of these studies in the coming months.”
The published data show that FATE-NK100 exhibits greater natural cytotoxicity and antibody-dependent cellular cytotoxicity against a variety of solid tumor cell lines and markedly increases cytokine production in response to target cell recognition. Additionally, in a xenogeneic model of ovarian cancer, the data show that FATE-NK100 exhibits better and more consistent anti-tumor efficacy.
The clinical trial in ovarian cancer cleared for conduct by the FDA is expected to evaluate the safety and determine the maximum dose of a single infusion of FATE-NK100 when administered intraperitoneally in the outpatient setting. An accelerated dose escalation design is intended to test up to three dose levels of FATE-NK100 with one subject enrolled per dose level. If a dose-limiting toxicity (DLT) is observed, the study will convert to a 3+3 design. A ten subject expansion cohort is planned at the maximum dose level. Other endpoints include objective response rate at 28 days post-infusion and of progression-free and overall survival at six months post-infusion.
The Masonic Cancer Center, University of Minnesota is currently conducting an investigator-initiated clinical trial of FATE-NK100 for the treatment of refractory or relapsed acute myelogenous leukemia. In addition, in May 2017, the FDA authorized an IND application for the clinical investigation of FATE-NK100 in combination with monoclonal antibody therapy in subjects with advanced solid tumors who have failed approved therapies.
FATE-NK100 is a first-in-class 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 and the memory-like activating receptor NKG2C. FATE-NK100 is produced through a feeder-free, seven-day manufacturing process during which NK cells sourced from a healthy donor are activated ex vivo with pharmacologic modulators.
