Drug Candidate for Treatment of Pain

APD371, an orally available agonist of the CB2 receptor, is an internally discovered investigational drug candidate that Arena is exploring for potential development in several indications, including pain. This compound, through its selectivity, is designed to provide pain relief without psychotropic effects and without the potential for dependence or abuse.


We have initiated a randomized, open-label and parallel Phase 2a clinical trial to evaluate the safety, tolerability and pharmacokinetics of multiple-ascending doses of APD371.
