Thetis Pharmaceuticals Announces Patent Issuance in Japan for its Resolvin E1 candidate, TP-317, for Cancer and Autoimmune Diseases (8/23/2021)

RIDGEFIELD, CT – (August 23, 2021) – Thetis Pharmaceuticals LLC, a privately-held biopharmaceutical company developing Resolvin-based therapies, announced today that the Japanese Patent Office has granted patent JP 6906047 providing composition of matter protection for its lead program TP-317 (Resolvins E1 magnesium lysinate) for solid tumor cancers and inflammatory bowel disease.

“TP-317 is a novel small molecule that represents a highly differentiated approach to regulating immune homeostasis with broad therapeutic potential in cancer and autoimmune diseases,” said Gary Mathias, co-founder and CEO of Thetis. “With long-term patents issued in the U.S., Europe, and Japan, TP-317 has the intellectual property foundation to support clinical development in major markets.”

About TP-317

TP-317 is a new molecular entity that delivers Resolvin E1, a naturally-occurring lipid mediator discovered by biomedical researchers at Harvard Medical School. TP-317 offers a novel approach to reprogram the tumor microenvironment and activate anti-tumor immunity. TP-317 has demonstrated potent single-agent activity in multiple tumor models, and additive effects with chemotherapy and checkpoint inhibitors in cold tumors. Based on this data and a comprehensive safety package, TP-317 is being developed as a once per week subcutaneous injection for solid tumor cancers, including pancreatic and metastatic colorectal cancer.

TP-317 is also being developed as an oral once-per-day therapy for inflammatory bowel disease (IBD) including Crohn’s disease and ulcerative colitis. Based on its unique, non-immunosuppressive mechanism of action, TP-317 is differentiated from approved and current investigational IBD drugs and is targeted at patients with mild-to-moderate IBD before escalation to immunosuppressive biologics and immunomodulators. Phase 1 data indicating that Resolvin E1 is safe and well-tolerated in healthy volunteers have been reviewed by regulatory authorities to support clinical development.
