Trevena Announces Presentations during PAINWeek® 2017

(September 07, 2017)

Hospital charge database study shows high prevalence of opioid-related adverse events in key surgical specialties despite use of multimodal analgesia

Physician survey highlights the need for new options for patients who require IV opioids but are at risk of opioid-related adverse events

CHESTERBROOK, Pa., Sept. 07, 2017 (GLOBE NEWSWIRE) -- Trevena, Inc. (NASDAQ:TRVN) today announced results from three poster presentations given during PAINWeek® 2017, held at The Cosmopolitan Hotel in Las Vegas, Nevada, September 5-9. The presentations described new data highlighting the burden of opioid-related adverse events in hospital patients who require intravenous (IV) opioids to manage their pain, and identified specific procedures and patient characteristics associated with elevated risk of acute opioid-related adverse events.

?These hospital database and survey data show that conventional IV opioids remain a necessary component of acute postoperative pain management, despite their many drawbacks, said Peter Whang, M.D., FACS, Associate Professor of Orthopaedics & Rehabilitation at Yale University School of Medicine. The findings highlight that patients who most require IV opioids, but are at elevated risk from opioid-related adverse events, reflect an important unmet need for new analgesic options.

Two of the poster presentations described the results of a study assessing patient characteristics and other predictors of post-operative nausea/vomiting (PONV) and opioid-induced respiratory depression (OIRD) associated with the use of conventional parenteral opioids to manage acute postoperative pain.  The study assessed 592,127 hospital stays in the Premier Perspectives® Hospital Database for general/colorectal, orthopedic, OB/GYN, cardiothoracic/vascular, and urologic procedures. These procedures are associated with severe and prolonged pain, and with patient risk factors that have been suggested to elevate the risk for opioid-related adverse events.  Despite the widespread use of multimodal analgesia, substantial doses of parenteral opioids were administered to these patients, ranging from 27 mg to 79 mg of morphine equivalents per day.  This was associated with high rates of OIRD, with incidence from 3% to 17% across the different surgical specialties.  Obesity, respiratory conditions, and sleep apnea were significantly associated with an increased likelihood of OIRD.  The study also found high rates of PONV, with incidence ranging from 44% to 72%.  Female patients and younger patients were found to have an increased likelihood of PONV. The prevalence of these adverse events was higher in this databases population than broader hospitalized patient populations studied in previous publications. 

A third poster described a recent survey of 501 physicians on their practice patterns in managing acute postoperative pain.  Results indicate that both patient characteristics (such as chronic opioid use, age, and respiratory comorbidities) and opioid-related adverse events (such as nausea, vomiting, and respiratory depression) remain a common challenge in postoperative pain management and play a key role in influencing treatment decisions, particularly in high-risk patients.
