Etrasimod Phase 3 trial shows positive results in Ulcerative Colitis patients: Pfizer
New York: Pfizer Inc. has announced positive topline results from a Phase 3 study of etrasimod, an investigational, oral, once-a-day, selective sphingosine 1-phosphate (S1P) receptor modulator in development for the treatment of moderately to severely active ulcerative colitis (UC).
In the study, etrasimod patients achieved statistically significant improvements in the primary endpoint of clinical remission at week 12 as compared with placebo. Statistically significant improvements were achieved in all key secondary endpoints in the trial as well. The safety profile was consistent with previous Phase 2 studies.
"These positive results demonstrate that etrasimod, if approved, could be a potential breakthrough option for patients with ulcerative colitis who aren't able to experience improvement on current therapies," said Michael Corbo, Chief Development Officer, Inflammation & Immunology, Pfizer Global Product Development. "This outcome represents a continuation of our effort to develop new therapeutic approaches to treat immuno-inflammatory diseases and address the need for oral therapies for UC patients with inadequate response, loss of response, or intolerance to conventional or advanced therapies."
