Dolcanatide

Dolcanatide is our second uroguanylin analog currently being explored for ulcerative colitis. Dolcanatide is designed to replicate the activity of uroguanylin with enhanced resistance to standard digestive breakdown by proteases in the intestine.

In January 2016, we announced positive proof-of-concept with dolcanatide in a phase 1b trial evaluating 28 patients with mild-to-moderate ulcerative colitis. We are planning to meet with regulatory agencies to discuss phase 2 clinical development plans for dolcanatide in mild-to-moderate ulcerative colitis. In November 2014, we reported successful proof-of-concept with dolcanatide in a double-blind, placebo-controlled phase 2 trial in 289 patients with OIC, demonstrating the utility of our uroguanylin analog technology platform in OIC.
