Trevena Announces Initial Topline OLINVYK Data from
~200 Patient Real-World Clinical Outcomes Study
OLINVYK-treated patients had a statistically significant 1.6 day (~27%) reduction in average overall hospital length of stay compared to matched patients treated with other IV opioids, based on initial EMR analysis of ARTEMIS patients at Wake Forest Baptist Health
OLINVYK-treated patients had a 52.2% GI complete responder rate, defined as no vomiting and no antiemetic use throughout the post-operative period, based on initial topline data from the VOLITION (n=203) real world outcomes study
Over 90% of OLINVYK-treated patients in VOLITION reported feeling “alert and calm” from the morning of the first post-operative day and at every observation point thereafter, based on the Richmond Agitation-Sedation Scale
Only 3.9% of OLINVYK-treated patients in VOLITION exhibited symptoms suggestive of delirium at any point in the 48-hour post-operative observation point, based on 3D-CAM assessment
CHESTERBROOK, Pa., March 30, 2023 (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 initial topline OLINVYK data from two related real-world outcomes studies: VOLITION and ARTEMIS.
The VOLITION study (n=203 patients), a real-world, open-label, multi-site study, assessed the potential impact of OLINVYK on respiratory, gastrointestinal (GI), and cognitive function outcomes in the postoperative setting, and was led by clinical outcomes research experts from the Cleveland Clinic and the Wake Forest Baptist Health Medical Center. Initial GI and cognition data are available, with respiratory outcome data expected mid-2023.
The ARTEMIS study was an electronic medical records (EMR) based assessment focused on clinical and health resource utilization outcomes. The study reviewed OLINVYK-treated patients in the VOLITION study with comparable surgical patients treated with other IV opioids, at the same institutions and during the same general time period. Initial ARTEMIS data from Wake Forest Baptist Health is currently available, representing 96 OLINVYK-treated patients and 457 matched patients treated with other IV opioids.
VOLITION Preliminary Topline Results (n=203)
| ● | GI Complete Responder Rate (prespecified exploratory endpoint). 52.2% of OLINVYK-treated patients were classified as GI complete responders, defined as no vomiting and no antiemetic use throughout the postoperative period. As reference, in pooled data for the Company’s pivotal Phase 3 studies of OLINVYK, the GI complete response rate was 46.2% (0.35mg) and 39.7% (0.5mg). As reflected in the OLINVYK label, nausea and vomiting were two of the most common adverse events reported in the controlled clinical trials. |
| ● | Wakefulness / Sedation (prespecified exploratory endpoint). Over 90% of OLINVYK-treated patients reported feeling “alert and calm” from the morning of the first post-operative day and at every observation point thereafter, based on the Richmond Agitation-Sedation Scale. Sedation is an established risk of opioids including OLINVYK. |
| ● | Cognition (prespecified exploratory endpoint). Only 3.9% of OLINVYK-treated patients exhibited symptoms suggesting delirium at any point in the 48-hour post-operative period. Symptoms suggestive of delirium were assessed based on the validated 3D-CAM screening tool. |
| ● | Data from Primary, Secondary and Other Exploratory Endpoints. Data is not yet available for other endpoints, including the primary and secondary respiratory endpoints, as well as other prespecified exploratory endpoints. The Company expects to report these data mid-2023. |
| ● | Tolerability. No drug-related serious adverse events (SAEs) and no deaths were reported in the VOLITION study. Data on other adverse events is not yet available, and the Company expects to report these data mid-2023. |
ARTEMIS (EMR-Based) Initial Results from Wake Forest Baptist Health
| ● | Healthcare Utilization Measures. OLINVYK-treated patients had a statistically significant 1.6 day (~27%) reduction in average overall hospital length of stay compared to matched patients treated with other IV opioids (P=0.0001), based on initial EMR analysis of matched patients at the Wake Forest Baptist Health study site. There was no statistically significant difference in the average duration of time in the post-anesthesia care unit (PACU), with 2.4 hours observed for both OLINVYK-treated and matched patients (P=0.8174). |
| ● | Delirium. Twenty (4.4%) matched patients experienced ICD-coded delirium or altered consciousness, compared to one patient (1.0%) with OLINVYK, though this difference was not statistically significant (P=0.27) |
Patients receiving any IV opioid who experienced delirium or altered consciousness in this study had an average hospital length of stay 10.5 days longer than patients who did not experience this event. ICD-coding was used for this comparative analysis as 3D-CAM is not generally used in the general patient population.
| ● | Initial EMR Data Set. ARTEMIS is an electronic medical records (EMR) data analysis, with records available from the Wake Forest Baptist Health study site (n=96 OLINVYK-treated patients; n=457 matched patients on other IV opioids). While an EMR analysis does not provide definitive data of group differences as seen in a prospectively randomized study, we believe EMR data bring a unique perspective to an understanding of how drugs may perform in the real world. |
VOLITION and ARTEMIS Study Details
VOLITION is a real-world, open-label, multi-site, post-approval clinical outcomes study in 203 adult patients undergoing major non-cardiac surgery. IV OLINVYK was dosed as the first-line analgesic during post-operative care, with a 1.5mg loading dose of OLINVYK at surgical closure, and 0.35mg to 0.5mg of OLINVYK, as needed, administered with a PCA device, with a 6-minute lockout period. Additional boluses (≤1 mg) of OLINVYK were available if needed as soon as 15 minutes after the initial 1.5 mg loading dose.
The average age of patients in VOLITION was 57.1 years (range 19 to 89), with approximately equal representation of men and women. Approximately 85% of patients underwent an abdominal surgical intervention, such as partial or total colectomy, enterotomy or other open abdominal procedures. A majority of patients had significant morbidity at the time of surgery as reflected by an ASA status, and their respiratory risk was intermediate to high risk, graded using the PRODIGY risk score. The average duration of the surgery was 4.7 hours (range of 1.2 to 12.6 hours).
ARTEMIS is an EMR-based analysis that compared the health outcomes of VOLITION study patients with a matched population of patients, who underwent similar surgical procedures but were treated with other IV opioids, at the same institutions and during the same general time period as VOLITION. Matching was conducted with a greedy matching algorithm, using a propensity scoring method with eight different demographic and clinical characteristics including age, sex, type and duration of surgery, measures of overall surgical and medical morbidity, and type of hospital insurance.
About OLINVYK® (oliceridine) injection
OLINVYK is a new chemical entity approved by the FDA in August 2020. OLINVYK contains oliceridine, an opioid, which is a Schedule II controlled substance with a high potential for abuse similar to other opioids. It is indicated in adults for the management of acute pain severe enough to require an intravenous opioid analgesic and for whom alternative treatments are inadequate. OLINVYK is available in 1 mg/1 mL and 2 mg/2 mL single-dose vials, and a 30 mg/30 mL single-patient-use vial for patient-controlled analgesia (PCA). Approved PCA doses are 0.35 mg and 0.5 mg and doses greater than 3 mg should not be administered. The cumulative daily dose should not exceed 27 mg. Please see Important Safety Information, including the BOXED WARNING, and full prescribing information at www.OLINVYK.com.
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 an opioid agonist 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]:
| ● | Have not been tolerated, or are not expected to be tolerated |
| ● | Have not provided adequate analgesia, or are not expected to provide adequate analgesia. |
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:
| ● | Significant respiratory depression |
| ● | Acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment |
| ● | Known or suspected gastrointestinal obstruction, including paralytic ileus |
| ● | Known hypersensitivity to oliceridine (e.g., anaphylaxis) |
WARNINGS AND PRECAUTIONS
| ● | OLINVYK contains oliceridine, a Schedule II controlled substance, that exposes users to the risks of addiction, abuse, and misuse. Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed OLINVYK. Assess risk, counsel, and monitor all patients receiving opioids. |
| ● | Serious, life-threatening respiratory depression has been reported with the use of opioids, even when used as recommended, especially in patients with chronic pulmonary disease, or in elderly, cachectic and debilitated patients. The risk is greatest during initiation of OLINVYK therapy, following a dose increase, or when used with other drugs that depress respiration. Proper dosing of OLINVYK is essential, especially when converting patients from another opioid product to avoid overdose. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status. |
| ● | Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia with risk increasing in a dose-dependent fashion. In patients who present with CSA, consider decreasing the dose of opioid using best practices for opioid taper. |
| ● | Prolonged use of opioids during pregnancy can result in withdrawal in the neonate that may be life-threatening. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise pregnant women using OLINVYK for a prolonged period of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available. |
| ● | Profound sedation, respiratory depression, coma, and death may result from the concomitant use of OLINVYK with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, or alcohol). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate, prescribe the lowest effective dose, and minimize the duration. |
| ● | OLINVYK was shown to have mild QTc interval prolongation in thorough QT studies where patients were dosed up to 27 mg. Total cumulative daily doses exceeding 27 mg per day were not studied and may increase the risk for QTc interval prolongation. Therefore, the cumulative total daily dose of OLINVYK should not exceed 27 mg. |
| ● | Increased plasma concentrations of OLINVYK may occur in patients with decreased Cytochrome P450 (CYP) 2D6 function or normal metabolizers taking moderate or strong CYP2D6 inhibitors; also in patients taking a moderate or strong CYP3A4 inhibitor, in patients with decreased CYP2D6 function who are also receiving a moderate or strong CYP3A4 inhibitor, or with discontinuation of a CYP3A4 inducer. These patients may require less frequent dosing and should be closely monitored for respiratory depression and sedation at frequent intervals. Concomitant use of OLINVYK with CYP3A4 inducers or discontinuation of a moderate or strong CYP3A4 inhibitor can lower the expected concentration, which may decrease efficacy, and may require supplemental doses. |
| ● | Cases of adrenal insufficiency have been reported with opioid use (usually greater than one month). Presentation and symptoms may be nonspecific and include nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If confirmed, treat with physiologic replacement doses of corticosteroids and wean patient from the opioid. |
| ● | OLINVYK may cause severe hypotension, including orthostatic hypotension and syncope in ambulatory patients. There is increased risk in patients whose ability to maintain blood pressure has already been compromised by a reduced blood volume or concurrent administration of certain CNS depressant drugs (e.g., phenothiazines or general anesthetics). Monitor these patients for signs of hypotension. In patients with circulatory shock, avoid the use of OLINVYK as it may cause vasodilation that can further reduce cardiac output and blood pressure. |
| ● | Avoid the use of OLINVYK in patients with impaired consciousness or coma. OLINVYK should be used with caution in patients who may be susceptible to the intracranial effects of CO2 retention, such as those with evidence of increased intracranial pressure or brain tumors, as a reduction in respiratory drive and the resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy. |
| ● | As with all opioids, OLINVYK may cause spasm of the sphincter of Oddi, and may cause increases in serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis, for worsening symptoms. |
| ● | OLINVYK may increase the frequency of seizures in patients with seizure disorders and may increase the risk of seizures in vulnerable patients. Monitor patients with a history of seizure disorders for worsened seizure control. |
| ● | Do not abruptly discontinue OLINVYK in a patient physically dependent on opioids. Gradually taper the dosage to avoid a withdrawal syndrome and return of pain. Avoid the use of mixed agonist/antagonist (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving OLINVYK, as they may reduce the analgesic effect and/or precipitate withdrawal symptoms. |
| ● | OLINVYK may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. |
| ● | Although self-administration of opioids by patient-controlled analgesia (PCA) may allow each patient to individually titrate to an acceptable level of analgesia, PCA administration has resulted in adverse outcomes and episodes of respiratory depression. Health care providers and family members monitoring patients receiving PCA analgesia should be instructed in the need for appropriate monitoring for excessive sedation, respiratory depression, or other adverse effects of opioid medications. |
ADVERSE REACTIONS
Adverse reactions are described in greater detail in the Prescribing Information.
