SAN DIEGO, April 1, 2020 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) today announced positive topline data from a Phase 1 clinical study evaluating controlled-release delivery profiles (CR) for its investigational agent, etrasimod, a highly selective, once-daily, oral sphingosine 1-phosphate (S1P) receptor modulator.
Results from the study demonstrated that CR delivery enabled a greater than 75% reduction in the average heart rate effect of etrasimod during its 4-hour monitoring period, with heart rate slowing by only low single digits from baseline with no titration. At additional measurements over 24 hours, the etrasimod CR heart rate effect was reduced or similar compared to etrasimod. Of note, the rate of change in heart rate was reduced greater than 50% with etrasimod CR delivery.
On the basis of these results, Arena will embark on a product development program to rapidly develop etrasimod CR and integrate it into multiple, ongoing clinical development programs. Additionally, a recently filed provisional patent application for etrasimod CR has the potential to extend patent coverage beyond that for the composition of matter plus patent term extension.
"Etrasimod currently has a potential best-in-class profile as a rapid-acting, non-titrated oral therapy with limited first-dose heart rate effect. It is exciting that Arena's etrasimod CR program has the potential to further differentiate this profile," stated Preston Klassen, MD, MHS, Executive Vice President, Research and Development at Arena. "This work builds on Arena's more than twenty-year scientific expertise in G-protein coupled receptor (GPCR) drug development and has the potential to improve etrasimod's broad clinical utility. We intend to launch in ulcerative colitis with etrasimod and expect to move to etrasimod CR with other ongoing and future development programs across a broad range of immune-mediated inflammatory diseases."
