One-time Administration of Programmed Cells Demonstrates Durable Disease Correction
in Type 1 Diabetes Mouse Model
ToleraCyte™ Product Candidate Exhibits Enhanced Trafficking to the Pancreas and Potent Regulation of
Autoreactive T Cells in Preclinical Testing
Preclinical Data Package to be Presented at American Diabetes Association’s 76th Scientific Sessions
SAN DIEGO, June 11, 2016 (GLOBE NEWSWIRE) -- Fate Therapeutics, Inc. (NASDAQ:FATE), a biopharmaceutical company dedicated to the development of programmed cellular immunotherapies for cancer and immune disorders, announced today that it will present preclinical data for ToleraCyte™, its programmed CD34+ immuno-regulatory cell product candidate for autoimmune diseases, at the American Diabetes Association’s 76th Scientific Sessions being held June 10-14 in New Orleans, Louisiana. Scientists from Fate Therapeutics and Boston Children’s Hospital demonstrated that a single administration of programmed cells results in durable correction of type 1 diabetes in a well-established non-obese diabetic (NOD) mouse model. In addition, the group showed that a single administration of programmed cells significantly delays the onset of type 1 diabetes in NOD mice. Fate Therapeutics is advancing ToleraCyte through late-stage preclinical development under a collaboration with Boston Children’s Hospital led by Paolo Fiorina, M.D., Ph.D., Assistant Professor of Pediatrics at Boston Children's Hospital and Harvard Medical School.
“The use of a programmed CD34+ cell therapy is an intriguing new therapeutic approach with disease-modifying potential for patients with type 1 diabetes, and the preclinical data suggest that CD34+ cells may play a critical role in treating autoimmunity,” said Michael J. Haller, M.D., an associate professor of pediatric endocrinology at University of Florida and an active investigator in Type 1 Diabetes TrialNet clinical studies. “These data are especially interesting given we have recently shown in a clinical study conducted at the University of Florida that treating patients with G-CSF, a CD34+ cell mobilizing agent, in combination with a mild conditioning regimen, preserved beta cell function in patients with established type 1 diabetes.”
The scientific team at Fate Therapeutics and Boston Children’s Hospital explored the disease-modifying potential of ToleraCyte in humanized and mouse models of type 1 diabetes. In in vivo studies using hyperglycemic NOD mice designed to mimic new-onset type 1 diabetes, a one-time administration of programmed cells resulted in the durable correction of disease, as compared to vehicle-treated cells. Additionally, in pre-hyperglycemic NOD mice, a one-time administration of programmed cells demonstrated a statistically-significant delay in the onset of disease, where the median time to onset was not reached by Day 140 as compared to untreated mice (median time to onset = Day 115; p=0.0004). Finally, in a humanized model of type 1 diabetes, programmed CD34+ cells showed enhanced trafficking to the pancreas and regulation of T-cell activation. Together, these preclinical results support the premise that ToleraCyte may serve as a disease-modifying immunotherapy for patients with type 1 diabetes.
“We believe ToleraCyte holds unique potential to immunologically check autoreactive T cells that are directly responsible for the destruction of healthy tissue in certain autoimmune and inflammatory disorders,” said Dan Shoemaker, Ph.D., Chief Scientific Officer of Fate Therapeutics. “Our programmed CD34+ cells exhibit enhanced trafficking and possess potent immuno-regulatory capabilities, expressing powerful T-cell regulatory factors including PD‐L1 and IDO1.”
The Company’s poster presentation entitled “Using Pharmacologically Programmed CD34+ Cells for the Treatment of Type 1 Diabetes” will be held on Sunday, June 12, 2016 at the American Diabetes Association’s 76th Scientific Sessions from 12:00 – 2:00 p.m. CT. The presentation will be available for review on the Publications section of the Company’s website at www.fatetherapeutics.com/publications following its conclusion.
ToleraCyte is a programmed CD34+ cell immunotherapy that is undergoing preclinical investigation for the treatment of autoimmune and inflammatory disorders. The immuno-regulatory cell therapy is comprised of CD34+ cells that have been programmed ex vivo with a proprietary combination of pharmacologic modulators. ToleraCyte is designed to optimize the capacity of CD34+ cells to effectively traffic to sites of inflammation and express potent T-cell regulatory factors, including PD‐L1 and IDO1.
