SAN DIEGO, Oct. 8, 2018 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) today announced that data from its OASIS Phase 2 clinical study for its investigational drug candidate etrasimod, a next-generation, oral, S1P receptor modulator with optimized activity being evaluated in ulcerative colitis (UC), were presented by Dr. William J. Sandborn at the American College of Gastroenterology Annual Meeting.  The paper was awarded the 2018 ACG Auxiliary Award Recipient (Member).  

"We are pleased to share data which we believe further support a direct readthrough to our Phase 3 program in UC.  Our Phase 2 results demonstrated the potential of etrasimod to allow patients to achieve clinical remission and meaningful improvements in the endpoints measured," said Preston Klassen, MD, MHS, Executive Vice President, Research and Development and Chief Medical Officer of Arena.  "We look forward to additional discussions with the regulatory agencies and moving rapidly into Phase 3."

These data will also be presented at the United European Gastroenterology Week (UEGW) in Vienna later this month. 

Presentation Details
Title:  A Randomized, Double-Blind, Placebo-Controlled Trial of a Selective, Oral Sphingosine 1-Phosphate (S1P) Receptor Modulator, Etrasimod (APD334), in Moderate to Severe Ulcerative Colitis (UC): Results From the OASIS Study
When: Monday, October 8, 2018, 2:15 PM - 2:25 PM EDT

About Etrasimod
Etrasimod (APD334), is a next generation, oral, selective sphingosine 1 phosphate (S1P) receptor modulator, discovered by Arena, designed to provide systemic and local cell modulation by selectively targeting S1P receptor subtypes 1,4 and 5. Etrasimod has therapeutic potential in immune and inflammatory-mediated diseases such as ulcerative colitis, Crohn's disease, primary biliary cholangitis (PBC) and atopic dermatitis. S1P receptors have been demonstrated to be involved in the modulation of several biological responses, including lymphocyte trafficking from lymph nodes to the peripheral blood. By isolating subpopulations of lymphocytes in lymph nodes, fewer immune cells are available in the circulating blood to effect tissue damage.

Etrasimod is an investigational compound that is not approved for any use in any country.

About Arena Pharmaceuticals
Arena Pharmaceuticals is focused on delivering novel, transformational medicines with optimized pharmacology and pharmacokinetics to patients globally. Arena's proprietary pipeline includes multiple potentially first- or best-in-class programs with broad clinical utility. The most advanced investigational clinical programs are ralinepag (APD811), in a Phase 3 program for pulmonary arterial hypertension (PAH), and etrasimod (APD334), expected to commence a Phase 3 program for ulcerative colitis (UC) and a program in Crohn's disease (CD), and which has potential utility for a broad range of immune and inflammatory-mediated. Arena is also evaluating olorinab (APD371) for the treatment of gastrointestinal pain, as well as other drug candidates in earlier research and development stages.

In addition, Arena has several collaborations including with Everest Medicines Limited (ralinepag and etrasimod in Greater China and select Asian countries), Axovant Sciences GmbH (nelotanserin - Phase 2), Boehringer Ingelheim International GmbH (undisclosed target - preclinical), Outpost Medicine, LLC (undisclosed target – preclinical), and Eisai Co., Ltd. and Eisai Inc. (BELVIQ® - marketed product).
