An Investigational Drug (TPST-1495) in Patients With Familial Adenomatous Polyposis

Summary

This open-label phase II trial tests how well TPST-1495 works in reducing the number of polyps in the small bowel and colon in patients with familial adenomatous polyposis (FAP). FAP is an inherited condition in which numerous polyps (growths that protrude from mucous membranes) form on the inside walls of the colon and rectum. It increases the risk for colon cancer. TPST-1495 binds to specific prostaglandin receptors. TPST-1495 is a dual antagonist of the prostaglandin E2 (PGE2) receptor subtypes EP2 and EP4, while sparing the immune-stimulating EP1 and EP3 receptors. TPST-1495 may help reduce the number of polyps in the small bowel and colon in patients with FAP.
