About

Thetis Pharmaceuticals

Founded in 2011 by ex-Pfizer R&D executives and healthcare entrepreneurs, Thetis Pharmaceuticals LLC is a biopharmaceutical company developing novel lipid-based drug candidates for the treatment of gastrointestinal diseases with high unmet medical needs.


Using our proprietary HEALER™ platform technology, Thetis is developing small molecule pharmaceuticals based on bioactive lipids that occur naturally in humans and have known efficacy and safety in GI diseases. Our drug candidates have unique mechanisms of action compared to existing therapeutic agents, and prospects for abbreviated non-clinical and clinical development programs. They are new molecular entities with strong composition of matter protection.

We are pursuing development of our lead candidate TP-252 for the treatment of ulcerative colitis. This focus is based on independent Phase II clinical data showing that the active agent in TP-252 helps maintain remission in ulcerative colitis patients who are at increased risk of relapse. Thetis expects to begin Phase I clinical trials in 2018.

In addition, the active agent in TP-252 has been shown in randomized clinical studies to be effective in the treatment of familial adenomatous polyposis (FAP), a rare genetic disorder. Thetis has been granted orphan drug designation for TP-252 for the treatment of FAP, and is in discussions with FDA on the design of the clinical development program.

Beyond TP-252, Thetis is leveraging discoveries in the field of lipid biology to develop drugs based on Specialized Proresolving Mediators (SPMs). SPMs are extremely potent, naturally occurring lipid molecules that regulate and trigger inflammation resolution pathways, and offer a novel approach for inducing and maintaining remission in patients with IBD. The initial focus of our SPM-based candidate, TP-317, is on an orphan disease in IBD.

"We are committed to creating innovative products that improve the lives of patients suffering from GI diseases."
