FDA Approves Olinvyk

FDA Approves Olinvyk (oliceridine) Injection for the Management of Severe Acute Pain

CHESTERBROOK, Pa., Aug. 10, 2020 (GLOBE NEWSWIRE) -- Trevena, Inc. (Nasdaq: TRVN), a biopharmaceutical company focused on the development and commercialization of novel medicines for patients with central nervous system (CNS) disorders, today announced that the U.S. Food and Drug Administration (FDA) has approved Olinvyk in adults for the management of acute pain severe enough to require an intravenous opioid analgesic and for whom alternative treatments are inadequate. Olinvyk will be commercially available when the U.S. Drug Enforcement Administration (DEA) issues its controlled substance schedule in approximately 90 days.

“The approval of Olinvyk marks an exciting step forward in Trevena’s mission of translating cutting-edge scientific discovery into therapeutic benefit for patients in need. I would like to thank all of the patients, investigators, and our employees who helped us achieve this important milestone,” said Carrie L. Bourdow, President and Chief Executive Officer. “We will work quickly to bring this novel IV analgesic to patients and healthcare providers in need of alternative treatment options.”

Each year, approximately 45 million hospital patients in the United States receive an IV opioid to treat their acute pain. Many of these patients are complex and difficult to treat, such as the elderly, obese, or renally-impaired. Current hospital trends suggest that the number of these complex patients is growing, representing an increasing burden on the healthcare system.

Olinvyk is an opioid agonist that is the first new chemical entity in this IV drug class in decades and offers a differentiated profile that addresses a significant unmet need in the acute pain management landscape. Olinvyk delivers IV opioid efficacy with a rapid 2-5 minute onset of action. In addition, Olinvyk requires no dosage adjustments in patients with renal impairment, a large patient population with significant medical complications.

The FDA approval of Olinvyk was based on results from the Phase 3 development program, which evaluated Olinvyk in over 1,500 patients with moderate to severe acute pain. In two pivotal efficacy studies in hard- and soft-tissue surgical models, Olinvyk demonstrated rapid analgesic efficacy statistically significant vs. placebo. In a large, open-label, “real world” safety study, Olinvyk was safe and well-tolerated in a medically complex patient population, including the elderly, obese, and patients with comorbid conditions such as diabetes and sleep apnea.

“Complex patients present unique challenges in the management of their postoperative acute pain, due to the presence of medical comorbidities that can complicate dosing,” said Gregory Hammer, M.D., Professor of Anesthesiology, Perioperative and Pain Medicine, and of Pediatrics at Stanford University. “Olinvyk represents a new alternative for clinicians, due to its rapid onset of action, effective pain relief, and unique profile.”

The Company expects to make Olinvyk available in the fourth quarter of 2020 following scheduling by the DEA, which may take up to 90 days. The Company is committed to an ethical and responsible marketing campaign for Olinvyk and will have safeguards in place to monitor for and mitigate the risk of non-medical uses of Olinvyk.

The Company also today announced $54.8 million in cash and cash equivalents as of June 30, 2020, which the Company expects will be sufficient to fund operating expenses, including the commercialization of Olinvyk, through year-end 2021.

Olinvyk Efficacy and Safety Data

The efficacy of Olinvyk was established in two randomized, double-blind, placebo- and morphine-controlled studies which enrolled 790 patients with moderate to severe acute pain (pain intensity of ≥4 on a 0-10 numeric rating scale) after orthopedic surgery-bunionectomy or plastic surgery-abdominoplasty.

In each study, patients were randomized to one of three Olinvyk treatment regimens, a placebo-control regimen, or a morphine-control regimen. The loading dose for all Olinvyk treatment regimens was 1.5 mg; demand doses were 0.1, 0.35, or 0.5 mg, according to the assigned treatment group; supplemental doses were 0.75 mg. A lockout interval of 6 minutes was used for all PCA regimens. Etodolac 200 mg was available as rescue medication. Patients using the approved Olinvyk doses of 0.35 and 0.5 mg had a statistically significantly greater SPID-48/24 than patients using placebo.

The most common adverse reactions (≥10%) in these controlled trials were nausea, vomiting, dizziness, headache, constipation, pruritus, and hypoxia. When stratified by the 27 mg daily dosing limit, discontinuation of Olinvyk due to adverse reactions occurred in 4% of patients who received a daily dose ≤27 mg, and less than 1% of patients who received a daily dose >27 mg.

In an open-label safety study of patients with moderate to severe acute pain following a surgical procedure or due to a medical condition, a total of 768 patients received at least one dose of Olinvyk. Olinvyk was administered via clinician-administered bolus dosing, PCA, or a combination of the two. Bolus dosing was initiated at 1 to 2 mg, with supplemental doses of 1 to 3 mg every 1 to 3 hours, as needed, based on individual patient need and previous response to Olinvyk. If Olinvyk was administered via PCA, the loading dose was 1.5 mg, the demand dose was 0.5 mg, and the lockout interval was 6 minutes. Supplemental doses of 1 mg were given as needed, taking into account the patient's utilization of PCA demand doses, individual patient need, and previous response to Olinvyk.

The most frequent condition treated in the open-label safety study was postsurgical acute pain, and included (in order of decreasing frequency): orthopedic, gynecologic, colorectal, general, plastic, urologic, neurologic (including spinal), bariatric, and cardiothoracic surgical procedures. Of the 768 patients treated with Olinvyk, 32% were age 65 years or older and 78% had a Body Mass Index ≥ 25 kg/m2. Olinvyk was administered as needed; 55% of patients received Olinvyk via clinician bolus administration only, and 45% of patients received Olinvyk via PCA self-administration or a combination of clinician bolus- and PCA self-administration. Discontinuation of Olinvyk in this study due to adverse drug reactions occurred in 3% of patients who received a daily dose ≤27 mg and 1% of patients who received a daily dose >27 mg.

IMPORTANT SAFETY INFORMATION

WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; NEONATAL OPIOID WITHDRAWAL SYNDROME; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CENTRAL NERVOUS SYSTEM (CNS) DEPRESSANTS

Addiction, Abuse, and Misuse

Olinvyk exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient’s risk before prescribing Olinvyk, and monitor all patients regularly for the development of behaviors or conditions.

Life-Threatening Respiratory Depression

Serious, life-threatening, or fatal respiratory depression may occur with use of Olinvyk. Monitor for respiratory depression, especially during initiation of Olinvyk or following a dose increase.

Neonatal Opioid Withdrawal Syndrome

Prolonged use of Olinvyk during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

Risk From Concomitant Use With Benzodiazepines or Other CNS Depressants

Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate; limit dosages and durations to the minimum required; and follow patients for signs and symptoms of respiratory depression and sedation.

INDICATIONS AND USAGE

Olinvyk is a new chemical entity indicated in adults for the management of acute pain severe enough to require an intravenous opioid analgesic and for whom alternative treatments are inadequate.

Limitations of Use

Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, reserve Olinvyk for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products]:

The cumulative total daily dose should not exceed 27 mg, as total daily doses greater than 27 mg may increase the risk for QTc interval prolongation.

CONTRAINDICATIONS

Olinvyk is contraindicated in patients with:
