Trevena Reports Second Quarter 2016 Financial Results and Provides Corporate Update

- Oliceridine Phase 3 pivotal efficacy trials enrolling on schedule for top-line data in 1Q17 -

KING OF PRUSSIA, PA. Trevena, Inc. (NASDAQ: TRVN), a clinical stage pharmaceutical company focused on the discovery and development of biased ligands targeting G protein coupled receptors (GPCRs), today announced financial results for the quarter ended June 30, 2016 and provided an update regarding its ongoing clinical programs.

“This quarter marked an important milestone for the company’s oliceridine program with the initiation of our two Phase 3 pivotal efficacy trials,” said Maxine Gowen, Ph.D., chief executive officer. “Following our successful End-of-Phase-2 and Breakthrough Therapy designation meeting with the FDA in the first quarter, we were able to rapidly initiate the pivotal efficacy trials, which are enrolling well.”

Second Quarter and Recent Highlights

·                  Enrolled first patients in APOLLO-1 and APOLLO-2 Phase 3 trials of oliceridine. In June, the company announced the enrollment of the first patients in the APOLLO-1 and APOLLO-2 pivotal Phase 3 efficacy studies. APOLLO-1 is studying patients suffering moderate to severe pain for 48 hours after undergoing bunionectomy, while APOLLO-2 is studying patients suffering moderate to severe pain for 24 hours after undergoing abdominoplasty; both are 375-patient, multicenter, randomized, double-blind, placebo- and active-controlled studies. Patients are randomized to receive placebo, morphine, or one of three oliceridine regimens, all dosed as needed via patient-controlled analgesia (PCA) device for the management of their post-operative pain, with approximately 75 patients per study arm. The primary objective of both trials is to evaluate the analgesic efficacy of oliceridine versus placebo.  Secondary endpoints compare the efficacy, safety, and tolerability of oliceridine to morphine. The company continues to expect to release top-line data in the first quarter of 2017 and to file an NDA in the second half of 2017.

·                  Continued progress in the ATHENA multi-procedure safety study.  This trial, which initiated in the first quarter, complements the APOLLO studies and aims to evaluate the safety and tolerability of oliceridine in patients with moderate to severe acute pain caused by a broad range of medical conditions or surgeries. Patients are treated on an as-needed basis via IV bolus, PCA administration, or both, as determined by the investigator.

·                  Continued engagement at pain medicine conferences. During the quarter, the company made a total of 16 presentations at five different medical conferences, including the American Pain Society and American Society of Regional Anesthesia and Pain Medicine annual meetings.  New analyses of the company’s Phase 2 oliceridine data were presented, including:

·                  Responder rate analysis of the Phase 2b primary endpoint, which was used to design the primary analysis of the Phase 3 APOLLO studies.

·                  A pharmacokinetic/pharmacodynamic model of oliceridine analgesia, including simulations of dosing regimens used to inform dosing in the Phase 3 APOLLO studies.

At the Society for Ambulatory Anesthesia (SAMBA) 31st Annual Meeting, the company was awarded a First Place in Excellence and Innovation Award for its presentation of data from the oliceridine Phase 2 program.  Further presentations of oliceridine data at additional pain medicine conferences are expected in the second half of 2016, including at the American Society of Anesthesiology 2016 annual meeting in October.

·                  Results from TRV027 Phase 2b trial. In May, the company announced that TRV027 did not achieve primary or secondary endpoints in the Phase 2b BLAST-AHF trial in acute heart failure. In August 2016, Allergan, Plc (NYSE: AGN) notified the company that it does not intend to exercise its exclusive option to license TRV027.

Financial Results

Net loss attributable to common stockholders for the quarter ended June 30, 2016 was $19.2 million, or $0.37 per share, compared to $11.5 million, or $0.28 per share for the quarter ended June 30, 2015. Research and development expenses were $17.2 million in the second quarter of 2016 compared to $10.3 million for the same period in 2015, primarily due to increased clinical trial expenses associated with the oliceridine Phase 3 program. For the remainder of 2016, the company anticipates that research and development expenses will increase as compared to the first half of 2016, primarily as a result of the initiation of the APOLLO efficacy studies in June and the expected acceleration of the ATHENA safety study recruitment. General and administrative expenses were $3.7 million, compared to $3.1 million for the second quarter of 2015.

Cash, cash equivalents, and marketable securities totaled $144.5 million as of June 30, 2016, which Trevena expects will be sufficient to fund its operations into 2018.

About Trevena

Trevena, Inc. is a clinical stage biopharmaceutical company that discovers, develops, and intends to commercialize therapeutics that use a novel approach to target G protein coupled receptors, or GPCRs. Oliceridine (TRV130), Trevena’s lead product candidate, is the first pain program granted Breakthrough Therapy designation by the U.S. Food & Drug Administration and is in Phase 3 development for intravenous treatment of moderate to severe post-operative acute pain. In Phase 2b, intravenous oliceridine demonstrated rapid and powerful analgesic efficacy with reduced frequency of opioid-related adverse events including nausea, vomiting, and hypoventilation compared to intravenous morphine, thus offering a promising safety and tolerability profile compared to conventional opioid analgesics while providing powerful pain relief to patients.
