Trevena Granted Key U.S. Composition of Matter Patent for TRV130

Expansion of Intellectual Property Estate Strengthens Pain Program

KING OF PRUSSIA, Pa.--(BUSINESS WIRE)-- Trevena, Inc. (NASDAQ: TRVN), a clinical stage biopharmaceutical company focused on the discovery and development of G protein coupled receptor (GPCR) biased ligands, today announced that the U.S. Patent and Trademark Office (USPTO) has granted U.S. Patent No. 8,835,488, “Opioid receptor ligands and methods of using and making same.” The patent covers TRV130, compositions comprising TRV130, and methods of using TRV130 and is expected to provide patent coverage for TRV130 until at least 2032. Trevena currently is testing TRV130 for the treatment of postoperative pain in a Phase 2a/b clinical trial.

“This patent provides a solid foundation in the United States for the long-term protection of both the TRV130 molecule and its use in treating pain,” said Maxine Gowen, Ph.D., chief executive officer. “With pending patent applications directed to TRV130 in key international markets and this newly issued US patent, we believe we are on track to establish a comprehensive global patent portfolio for this key asset.”

About TRV130 and Acute Pain

Trevena anticipates that the initial market opportunity for TRV130 will be in the acute care hospital setting, with a focus on postoperative pain. Dosing of mu-opioid agonists, the most effective class of analgesics currently available, is limited by severe side effects such as respiratory depression, nausea and vomiting, constipation, and postoperative ileus, with the result that approximately 40% of surgical patients report moderate or severe pain while in the hospital despite the use of analgesics. Trevena believes that TRV130 may offer improved analgesia with reduced incidence and severity of these on-target adverse effects, which could help ease the suffering and burden of care for post-surgical pain, as well as the estimated $5 billion annual financial impact of opioid-related adverse effects in US hospitals.

TRV130 is a biased ligand targeting the mu-opioid receptor, the molecular target of analgesics such as fentanyl and morphine. Like these drugs, in preclinical studies TRV130 activates the mu-opioid G protein pathway, which is associated with analgesia; unlike these drugs, TRV130 inhibits the beta-arrestin pathway, the activation of which is associated with respiratory depression and constipation. In an experimental medicine study in healthy volunteers, published in the journal Pain in June 2014, TRV130 elicited superior analgesia, less respiratory depression, less vomiting, and less severe nausea than morphine. Earlier clinical and preclinical data were published in the Journal of Clinical Pharmacology and the Journal of Pharmacology and Experimental Therapeutics.
