Trevena Reports Third Quarter 2017 Financial Results and Announces New Positive Clinical Trial Data

— New ATHENA data show OLINVO effectiveness with promising safety/tolerability in key target procedures —

— Positive interim data for Phase 1 study of investigational migraine treatment TRV250 leads to study expansion —

CHESTERBROOK, PA, November 7, 2017 — Trevena, Inc. (NASDAQ: TRVN) today announced financial results for the quarter ended September 30, 2017, and announced positive new data from both its OLINVOTM (oliceridine injection) and TRV250 programs.

“The recent submission of the OLINVO NDA capped a transformative period for our Company,” said Maxine Gowen, Ph.D., chief executive officer. “We are now focused on preparing for the approval and commercialization of OLINVO, while continuing to advance our development pipeline following our recent strategic decision to halt our discovery research efforts.  To this end, new results continue to highlight the potential value of OLINVO for patients in a real world setting who require IV opioids but are at risk of opioid-related adverse events.  Positive interim Phase 1 data for TRV250 bode well for future clinical development of this exciting potential migraine therapy.”

Third quarter and recent corporate highlights

·                  OLINVO New Drug Application submitted. The Company recently submitted its New Drug Application (NDA) for OLINVO to the U.S. Food and Drug Administration (FDA).  OLINVO is the first G protein biased ligand of the mu opioid receptor, a new class of opioid receptor modulator, and the first pain program to receive Breakthrough Therapy designation from the FDA. The submission includes data showing that intravenous OLINVO demonstrated analgesic efficacy in all three dosing regimens tested in the two Phase 3 APOLLO pivotal efficacy studies.  These trials were designed to support an indication for the management of moderate-to-severe acute pain in adult patients for whom an intravenous opioid is warranted. The filing also includes safety and tolerability data for over 1,100 patients administered OLINVO across Phase 2 and Phase 3 studies, including the ATHENA open label safety study.  Additional pharmacokinetic data, clinical pharmacology data, and results from five randomized controlled trials with head to head comparisons to morphine, support potential differentiation of OLINVO.

·                  New data from Phase 3 ATHENA open label safety study.  In July, the Company announced top-line results from the first 418 patients administered OLINVO to manage medical or postoperative pain in the ATHENA study, which was designed to model real-world use including multimodal analgesia regimens incorporating OLINVO.  Data for all 768 patients administered OLINVO are now final, and highlight the effectiveness and utility of OLINVO in treating patients who require an IV opioid to manage pain.  Across the ATHENA study:

·                  The most common procedures were orthopedic, colorectal, gynecologic, and general surgeries.  Patients at elevated risk of opioid-related adverse events were well represented; more than 30% of patients were 65 years or older, and more than 50% of patients were obese, with body mass index (BMI) >30 kg/m(2).

·                  Only 2% of patients discontinued for adverse events, and 4% of patients discontinued for lack of efficacy.  The most common adverse events were nausea, constipation, and vomiting, with prevalence lower than in the APOLLO studies.  Adverse event rates associated with OLINVO administered by patient controlled analgesia (PCA) and as-needed bolus dosing were similar, supporting potential use of OLINVO in both administration paradigms.

·                  Hosted an Analyst Day featuring four leading experts in acute pain management in the hospital. In July, the Company hosted an Analyst Day where it outlined its commercial strategy for OLINVO, including plans to focus on patients who require IV opioids and are at greater risk of opioid-related adverse effects (ORAEs). These patients comprise approximately 7 to 9 million annual hospital inpatients in the United States.  Among other data presented, investigator-reported observations from the ATHENA study included a retrospective chart review at one site that found that colorectal surgery patients who received OLINVO showed return of bowel function 28 hours faster than similar patients treated with conventional opioids  (p=0.0001 vs. historical control at the same site).

·                  Continued publication and medical conference presentation of OLINVO data. The Company has continued to present OLINVO clinical data and analyses of unmet needs in acute pain in peer-reviewed journals and at medical meetings. OLINVO has also been featured in independent peer-reviewed publications.  Select presentations and publications included:

·                  Peer-reviewed publication of full Phase 2b results, by Singla et al: https://www.dovepress.com/getfile.php?fileID=38764

·                  Prevalence and costs of opioid-related adverse events presented at PainWeek and the American Society of Anesthesiologist annual meetings

·                  Unmet needs and potential new options in acute pain management, by Gan et al:
https://www.dovepress.com/getfile.php?fileID=38563

·                  Structural basis for the novel OLINVO mechanism of action, by Kappor et al: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5595830/pdf/41598_2017_Article_11483.pdf

·                  Joined a Department of Health and Human Services Secretarial Round Table on Opioids, held October 5, 2017 in Washington, D.C. The round table invited industry leaders, including Dr. Gowen, to discuss novel drugs and delivery systems that have the potential to improve pain management or reduce opioid addiction. At the meeting, Dr. Gowen emphasized that because IV opioids will remain necessary for millions of hospital patients, there is an urgent need for new options that may offer improved safety while helping to avoid unnecessarily prolonged exposure to opioids.

·                  Positive interim results of Phase 1 study of TRV250 for acute migraine. TRV250 is under investigation as a potential new mechanism of action for the acute treatment of migraine. The ongoing first-time-in-human Phase 1 trial is a single ascending dose study of safety, tolerability, and pharmacokinetics of both subcutaneous and oral TRV250 in healthy volunteers.  The Company has completed dosing of the initially planned cohorts.

·                  In the doses studied to date, TRV250 demonstrated dose-proportional exposure after s.c. administration.  TRV250 was well tolerated at all doses tested. Because no dose-limiting adverse events were identified in the initial cohorts of healthy subjects, the company has expanded the study to evaluate higher doses to support future Phase 2 planning.

·                  Preliminary data from oral administration of TRV250 to healthy volunteers suggest TRV250 has adequate oral bioavailability to support further clinical development.

·                  Discovery of novel S1P modulators, a new non-narcotic approach to managing chronic pain. In July, the Company disclosed a new preclinical lead optimization program targeting S1P receptors. The Company’s compounds are all new chemical entities, expected to be non-addictive, and use a new mechanism of action that in preclinical models avoids the immune suppression associated with approved and investigational S1P receptor targeted drugs.  These molecules have demonstrated activity in preclinical models of chemotherapy-induced peripheral neuropathy, neuropathic pain, and inflammatory pain.
