SAN DIEGO, April 10, 2014 (GLOBE NEWSWIRE) -- Fate Therapeutics, Inc. (Nasdaq:FATE), a biopharmaceutical company engaged in the discovery and development of adult stem cell modulators to treat orphan diseases, announced today that the U.S. Patent and Trademark Office (PTO) has issued Patent No. 8,691,573 entitled "Stem Cell Cultures." The newly issued patent claims a class of small molecule inhibitors of Rho-associated kinase (ROCK) that are crucial to the therapeutic application of human induced pluripotent stem cells (hiPSCs). Modulators belonging to the patented class have been shown to be necessary for the high-throughput derivation of transgene-free hiPSCs, and for the maintenance, survival and genomic stability of hiPSCs in culture. Fate Therapeutics holds an exclusive license from The Scripps Research Institute (TSRI) to the patent in all commercial fields.
"We believe the class of ROCK inhibitors covered by these issued claims is a key component to enable the clinical manufacture of hiPSCs for therapeutic applications," said Scott Wolchko, Chief Operating and Financial Officer of Fate Therapeutics. "These newly issued claims complement the hiPSC-related cell compositions previously patented under our Whitehead Institute for Biomedical Research intellectual property portfolio, which we believe are foundational to hiPSC generation. Our growing patent estate covering small molecule-enhanced reprogramming and pluripotency maintenance and expansion is a reflection of the breadth of our proprietary platform for developing iPSC-based regenerative therapeutics."
Thiazovivin, one specific ROCK inhibitor covered within the patented class, was first discovered by Sheng Ding, Ph.D., a scientific founder of Fate Therapeutics. Under a research collaboration between TSRI and Fate Therapeutics, Dr. Ding and his team first demonstrated that Thiazovivin, in combination with other small molecules, increases the reprogramming efficiency of human fibroblasts into hiPSCs by 200-fold as compared to non-chemically enhanced methods of hiPSC generation (Lin, T., et al, Nature Methods 6, 805 – 808 (2009)). Additional work by both Dr. Ding and Fate Therapeutics further differentiated the ability of Thiazovivin and its related class of molecules, as compared to other ROCK inhibitors, to significantly enhance hiPSC survival and homogeneity. Thiazovivin, as well as compositions and cell culture media comprising Thiazovivin, are patented under U.S. Patent No. 8,044,201 entitled "Stem Cell Cultures," to which Fate Therapeutics holds an exclusive license from TSRI in all commercial fields.
Last month, Fate scientists published an article in the journal Stem Cell Reports describing its proprietary stem cell modulation platform for developing hiPSC-based regenerative therapeutics. The Company's therapeutic platform consists of stage-specific cell culture systems containing combinations of small molecule modulators including ROCK inhibitors, and enables the rapid, parallel derivation of hiPSC clones and their subsequent expansion and survival as transgene-free, single cells in culture. Fate Therapeutics is currently researching therapeutic applications of hiPSC-derived myogenic progenitor cells and hematopoietic cells.
About Fate Therapeutics, Inc.
Fate Therapeutics is a clinical-stage biopharmaceutical company engaged in the discovery and development of pharmacologic modulators of adult stem cells to treat orphan diseases. The Company utilizes established pharmacologic modalities, including small molecules and therapeutic proteins, and well-characterized biological mechanisms to enhance the therapeutic potential of adult stem cells. The Company has built two adult stem cell modulation platforms: a hematopoietic stem cell (HSC) modulation platform, which seeks to optimize the therapeutic potential of HSCs for treating patients with hematologic malignancies and rare genetic disorders, and a muscle satellite stem cell modulation platform, which seeks to activate the regenerative capacity of muscle for treating patients with degenerative muscle disorders. The Company is presently advancing its lead product candidate, PROHEMA®, a pharmacologically-modulated HSC therapeutic, in Phase 2 clinical development for hematologic malignancies. Fate Therapeutics is also advancing its proprietary Wnt7a protein analogs in preclinical development for the treatment of muscular dystrophies. Fate Therapeutics is headquartered in San Diego, CA.
