SAN DIEGO, Calif., Sept. 26, 2019 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) presented new data from the Phase 2 OASIS trial for etrasimod, an investigational, once-daily, oral, selective sphingosine 1-phosphate (S1P) receptor modulator, in development for a range of immune-mediated and inflammatory conditions, including the ongoing ELEVATE UC Phase 3 trial that was initiated this year. These data were presented at the World Congress of Gastroenterology Meeting in Istanbul, Turkey.
"Steady-state etrasimod trough concentrations were achieved and maintained from weeks 1 to 12 in patients with moderately to severely active ulcerative colitis treated with 1 or 2 mg etrasimod once-daily. Statistically significant exposure-response relationships favoring 2 mg dosing were demonstrated, with reductions from baseline in circulating lymphocyte count and improvements in modified Mayo Clinic Score," stated Dr. Preston Klassen, Executive Vice President, Head of Research & Development at Arena. "In addition to previously reported dose-response data from OASIS, these new findings further strengthen the etrasimod 2 mg dosing regimen chosen for our Phase 3 ELEVATE UC program."
