Arena Pharmaceuticals Achieves Target Enrollment for Etrasimod Phase 3 ELEVATE UC 52 Trial

SAN DIEGO, Dec. 8, 2020 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) today announced that it has achieved its targeted enrollment goal of 372 participants in the Phase 3 ELEVATE UC 52 trial evaluating the safety and efficacy of once-daily etrasimod, a highly selective, once-daily, oral sphingosine 1-phosphate (S1P) receptor modulator, in participants with moderately-to-severely active ulcerative colitis. 

"We are pleased that we have achieved our target enrollment and maintained momentum, conduct, and timelines across the global ELEVATE UC program. While we have achieved our enrollment goal for the ELEVATE UC 52 trial, we have made the decision to extend screening an additional three weeks based on the high number of participants that we currently have in the screening queue. We continue to expect topline data from both the ELEVATE UC 52 and UC 12 trials in Q1 2022. We remain highly focused on successful clinical trial execution with careful attention to data integrity and the safety of the trial participants," stated Sheldon Sloan, MD, Vice President and Global Team Leader, Etrasimod, at Arena.

About ELEVATE UC 52
ELEVATE UC 52 is one of two pivotal trials that are part of the ELEVATE UC global Phase 3 registrational program. ELEVATE UC 52 is a 2:1 randomized, double-blind, placebo-controlled trial to assess the efficacy and safety of etrasimod 2 mg once-daily in participants with moderately to severely active ulcerative colitis (UC) defined as a baseline 3-domain, modified Mayo Score of 4 to 9 with an endoscopic score of 2 or more, and a rectal bleeding score of 1 or more. This is a one-year trial evaluating clinical remission at 12 weeks, or induction, and at 52 weeks. The trial consists of a 28-day screening period, a 12-week treatment period, a 40-week treatment period, and a 2-week follow-up period. The primary objective of this trial is to assess the safety and efficacy of etrasimod on clinical remission after both 12 and 52 weeks. The primary endpoint is the FDA-required, 3-domain, modified Mayo Score, which is similar to the endpoint in the Phase 2 OASIS study. Key secondary measures include the efficacy of etrasimod on clinical response, symptomatic response and remission, endoscopic changes, corticosteroid-free remission, and a total healing in these participants at time points up to 52 weeks of treatment. The ELEVATE UC program is being conducted in over 400 sites across more than 40 countries.
