SANTA MONICA, Calif., Feb. 21, 2019 (GLOBE NEWSWIRE) -- Opiant Pharmaceuticals, Inc. (NASDAQ:OPNT), a specialty pharmaceutical company developing medicines for addictions and drug overdose, today announced that its Phase 2 clinical trial evaluating OPNT001, a naloxone nasal spray for the treatment of bulimia nervosa (BN), did not meet the primary endpoint of reducing the number of binging days from baseline to week 8. Key secondary efficacy endpoints were also not met.  

“Based on these results, Opiant will not allocate further  resources to the development of OPNT001 for the treatment of BN, allowing us to invest more in our pipeline. The company’s focus for 2019 remains on conducting the pivotal trial for OPNT003, nasal nalmefene for opioid overdose, preparing to enroll patients into a Phase 2 study for OPNT002, nasal naltrexone, for the treatment of Alcohol Use Disorder and progressing the development of OPNT004, drinabant, for Acute Cannabinoid Overdose,” said Roger Crystal, M.D., Chief Executive Officer of Opiant. “We wish to express our gratitude to the investigators, as well as the patients and their families, for their support and participation in the BN study.”

In the Phase 2 trial, OPNT001 was generally safe and well-tolerated with minimal adverse events alongside good patient compliance.
