Trevena Announces FDA Acceptance for Review of New

Drug Application for OLINVO (oliceridine) Injection

January 2, 2018 — Trevena, Inc. (NASDAQ:TRVN) today announced that the U.S. Food and Drug Administration (FDA) has accepted the Company’s New Drug Application (NDA) for OLINVO™ (oliceridine) Injection.  The Company expects that the PDUFA date for the NDA will be in the fourth quarter of 2018.  OLINVO is an investigational product for the management of moderate to severe acute pain.  It is the first G protein biased ligand of the mu receptor designed to provide IV opioid pain relief with fewer associated adverse effects.

“The NDA file acceptance represents another major step in our progress towards delivering OLINVO to patients and healthcare providers in need of new options for managing moderate to severe acute pain in the hospital setting,” said Maxine Gowen, Ph.D., chief executive officer.  “We look forward to working with the FDA as they evaluate the OLINVO application.”

About OLINVO™ (oliceridine) Injection

OLINVO is a next generation IV analgesic for the management of moderate-to-severe acute pain in the hospital and similar settings and has been granted Breakthrough Therapy designation by the FDA. OLINVO was specifically designed to deliver the pain relief of a conventional IV opioid, with fewer associated adverse effects via its biased ligand mechanism of action. In Phase 2 and Phase 3 clinical trials, OLINVO provided rapid and powerful analgesic efficacy while demonstrating a wider therapeutic window compared to morphine, suggesting it may be highly effective and well-tolerated for patients in need of strong analgesia. OLINVO is an investigational product and has not been approved by the FDA or any other regulatory agency.  The Company expects OLINVO to be a Schedule II controlled substance.
