CHESTERBROOK, PA — Trevena, Inc. (Nasdaq: TRVN), a biopharmaceutical company focused on the development and commercialization of novel medicines for patients with central nervous system (CNS) disorders, announced a poster presentation at the 46th Annual Regional Anesthesiology and Acute Pain Medicine (ASRA) Meeting. The conference is taking place on May 13th to 15th, 2021.
The poster highlights an exploratory analysis of respiratory safety data from the OLINVYK Phase 3 multi-site, open-label, “real world” study. The incidence of opioid-induced respiratory depression (OIRD) was similar between “high-risk” patients, defined as elderly and obese, and “low-risk” patients, defined as younger and non-obese. This lack of difference was observed despite the high-risk group having a higher average age, average BMI, comorbid burden, mean cumulative dose, and mean duration of exposure to OLINVYK. Advanced age and obesity are two well-recognized risk factors for developing OIRD.
“Complex patients with medical comorbidities pose unique challenges in postoperative pain management, due to their increased risk for developing adverse events such as respiratory depression,” said Mark A. Demitrack, M.D., Senior Vice President and Chief Medical Officer of Trevena, Inc. “The findings from this analysis are important and suggest that OLINVYK may be a clinically appropriate treatment option for these challenging patients. Physicians still need to be mindful that life-threatening respiratory depression from opioids is more likely to occur in elderly patients. Physicians should monitor them closely, particularly when initiating and titrating OLINVYK and when OLINVYK is given concomitantly with other drugs that depress respiration.”
“Low Incidence of Opioid-Induced Respiratory Depression Observed with Oliceridine In High-Risk Elderly Obese Patients” (Poster #979, 5:30-6:00 p.m. ET, May 13th, 2021)
- High-risk patients (n=120) demonstrated a relatively low OIRD incidence of 10.8%, which was numerically lower than the OIRD incidence of 14.6% in low-risk patients (n=268) and 12.9% in all patients.
- Out of 768 patients in the study, 33% were ≥ 65 years of age and 46% had a BMI of ≥ 30 kg/m2. The average age in the high-risk group was 70 vs. 45 years in the low-risk group. The average BMI in the high-risk group was 35.6 kg/m2 vs. 25.1 kg/m2 in the low-risk group.
- The mean cumulative dose of OLINVYK was 37.1 mg in the high-risk group vs. 30 mg in the low-risk group. The mean duration of exposure was 39.8 hours in the high-risk group vs. 28.1 hours in the low-risk group.
- There was a higher incidence of other medical comorbidities in the high-risk group, including asthma, sleep apnea, chronic obstructive pulmonary disease, diabetes, and hypertension, which are also known to increase the risk of OIRD.
- OIRD was defined by administration of naloxone, a respiratory rate <10 bpm, or oxygen saturation < 90%. No naloxone administration was required for any patient treated with OLINVYK in the study.
