Thetis Announces Pre-Clinical Data on TP-252

BRANFORD, CT (May 8, 2017) – Thetis Pharmaceuticals, a pioneer in the development of novel lipid-based drugs for gastrointestinal diseases, today announced pre-clinical data for its lead candidate TP-252. In a study conducted at the Center for Molecular Medicine at UCONN Health Center, TP-252 was shown to produce a reduction in intestinal tumor burden that was equivalent to EPA-FFA in a mouse model of familial adenomatous polyposis (FAP). These data were presented today at Digestive Disease Week in Chicago.

TP-252 (magnesium lys-icosapentate) is a new drug that delivers the free fatty acid of eicosapentaenoic acid (EPA-FFA), a natural agent with demonstrated clinical efficacy in controlling colorectal polyp burden in FAP. Thetis Pharmaceuticals is pursuing TP-252 in FAP, a rare genetic pediatric disease characterized by hundreds to thousands of polyps in the colon that put patients at high risk for colorectal cancer.

“There is a tremendous unmet need for therapies to treat FAP in pediatric patients,” said Gary Mathias, Thetis co-founder and Chief Executive Officer. “While individuals with FAP ultimately require prophylactic colectomy, we believe that TP-252 has the potential to provide a clinically meaningful delay in surgery. That delay can be life changing in young patients for whom the co-morbidities and emotional burden of colectomy are frequently traumatic.”

About Familial Adenomatous Polyposis

Familial adenomatous polyposis (FAP) is a rare genetic disease for which there are no currently approved treatments. FAP is caused by a mutation of the APC gene, a gene that limits the growth of tumors. Nearly 100% of untreated FAP patients will develop colorectal cancer by the age of 60. The current standard of care includes endoscopic surveillance and ultimately, prophylactic colectomy. While a colectomy is effective at reducing the risk of colon cancer, it has major co-morbidities. Therefore, a safe, oral agent to delay surgery is a major unmet medical need for young FAP patients.
