Olorinab (APD371)

Drug Candidate for Treatment of Pain

Olorinab (APD371) is an oral, peripherally acting, highly-selective, full agonist of the cannabinoid receptor 2 (CB2). Olorinab is an internally discovered investigational drug candidate that Arena is exploring for development in several indications, with an initial focus on visceral pain associated with gastrointestinal disorders. This compound, through its selectivity for CB2, versus CB1, is designed to provide pain relief without psychoactive adverse effects.
