OLINVYK Solution for injection Ref.[10350] Active ingredients:

5.1 Addiction, Abuse, and Misuse

OLINVYK contains oliceridine, a Schedule II controlled substance. As an opioid, OLINVYK exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9)].

Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed OLINVYK. Addiction can occur at recommended dosages and if the drug is misused or abused [see Drug Abuse and Dependence (9)].

Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing OLINVYK, and monitor all patients receiving OLINVYK for the development of these behaviors or conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as OLINVYK, but use in such patients necessitates intensive counseling about the risks and proper use of OLINVYK along with intensive monitoring for signs of addiction, abuse, and misuse.

Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing OLINVYK. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity. Contact local state professional licensing board or state controlled substances authority for information on how to prevent and detect abuse or diversion of this product.

5.2 Life-Threatening Respiratory Depression

Serious, life-threatening respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical status [see Overdosage (10.2)]. Carbon dioxide (CO₂) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids.

While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of opioids, the risk is greatest during initiation of therapy or following a dose increase. Monitor patients closely for respiratory depression, especially when initiating therapy with OLINVYK and following dosage increases.

To reduce the risk of respiratory depression, proper dosing of OLINVYK is essential [see Dosage and Administration (2)]. Overestimating the OLINVYK dosage when converting patients from another opioid product can result in fatal overdose with the first dose.

Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia. Opioid use increases the risk of CSA in a dose-dependent fashion. In patients who present with CSA, consider decreasing the opioid dosage using best practices for opioid taper.

5.3 Neonatal Opioid Withdrawal Syndrome

Prolonged use of opioids during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life−threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise women using opioids for a prolonged period of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Use in Specific Populations (8.1)].

5.4 Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants

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.

Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of other CNS depressant drugs with opioid analgesics [see Drug Interactions (7)].

If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Follow patients closely for signs and symptoms of respiratory depression and sedation.

Advise both patients and caregivers about the risks of respiratory depression and sedation when OLINVYK is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs [see Drug Interactions (7), Patient Counseling Information (17)].

5.5 Potential for QT prolongation with Daily Doses exceeding 27 mg

The effect of oliceridine on cardiac physiology was studied in single and multiple-dose thorough QT studies. The multiple-dose study was conducted with a maximum daily cumulative dose of 27 mg. In both studies, there was mild QTc interval prolongation. In the multiple-dose study, the maximum mean ΔΔQTcI was 11.7 ms (two-sided 90% UCI 14.7 ms) at 9 hours. The effect on QT prolongation at total cumulative daily doses >27 mg has not been studied in a thorough QT study [see Clinical Pharmacology (12.2)]. Total cumulative daily doses exceeding 27 mg per day may increase the risk for QTc interval prolongation. Therefore, the cumulative total daily dose of OLINVYK should not exceed 27 mg [see Dosage and Administration (2.2)].

5.6 Risk of Use in Patients with Decreased Cytochrome P450 2D6 Function or Concomitant Use or Discontinuation with Cytochrome P450 3A4 Inhibitors and Inducers

Risk of Increased Oliceridine Plasma Concentrations

Increased plasma concentrations of oliceridine, which may result in prolonged opioid adverse reactions and exacerbated respiratory depression, may occur when OLINVYK is used under the following conditions:

• In patients with decreased Cytochrome P450 (CYP) 2D6 function (poor metabolizers of CYP2D6 or normal metabolizers taking moderate or strong CYP2D6 inhibitors) [See Drug Interactions (7) and Use in Specific Populations (8.8)].
• 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
• Discontinuation of a CYP3A4 inducer

These patients may require less frequent dosing of OLINVYK. Closely monitor these patients for respiratory depression and sedation at frequent intervals and base subsequent doses of OLINVYK on the patient’s severity of pain and response to treatment. [see Drug Interactions (7), Use in Specific Populations (8.8) Clinical Pharmacology (12.3, 12.5)].

Risk of Lower than Expected Oliceridine Plasma Concentrations

Lower than expected concentrations of oliceridine, which may lead to decreased efficacy, may occur under the following conditions:

• Concomitant use of OLINVYK with CYP3A4 inducers
• Discontinuation of a moderate or strong CYP3A4 or CYP2D6 inhibitor

Closely monitor these patients at frequent intervals and consider supplemental doses of OLINVYK [see Dosage and Administration (2.2) and Drug Interactions (7)].

5.7 Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients

The use of OLINVYK in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated.

Patients with Chronic Pulmonary Disease: OLINVYK-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages of OLINVYK [see Warnings and Precautions (5.2)].

Elderly, Cachectic, or Debilitated Patients: Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients as they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients [see Warnings and Precautions (5.2)].

Monitor such patients closely, particularly when initiating and titrating OLINVYK and when OLINVYK is given concomitantly with other drugs that depress respiration [see Warnings and Precautions (5.2, 5.4), Drug Interactions (7)]. Alternatively, consider the use of non-opioid analgesics in these patients.

5.8 Adrenal Insufficiency

Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Presentation of adrenal insufficiency may include non-specific symptoms and signs including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency. The information available does not identify any particular opioids as being more likely to be associated with adrenal insufficiency.

5.9 Severe Hypotension

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) [see Drug Interactions (7)]. Monitor these patients for signs of hypotension after initiating or titrating the dosage of OLINVYK. In patients with circulatory shock, OLINVYK may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of OLINVYK in patients with circulatory shock.

5.10 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness

In patients who may be susceptible to the intracranial effects of CO₂ retention (e.g., those with evidence of increased intracranial pressure or brain tumors), OLINVYK may reduce 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 with OLINVYK.

Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of OLINVYK in patients with impaired consciousness or coma.

5.11 Risks of Use in Patients with Gastrointestinal Conditions

OLINVYK is contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus.

OLINVYK may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis, for worsening symptoms.

5.12 Increased Risk of Seizures in Patients with Seizure Disorders

OLINVYK may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures occurring in other clinical settings associated with seizures. Monitor patients with a history of seizure disorders for worsened seizure control during OLINVYK therapy.

5.13 Withdrawal

Do not abruptly discontinue OLINVYK in a patient physically dependent on opioids. When discontinuing OLINVYK in a physically-dependent patient, gradually taper the dosage. Rapid tapering of oliceridine in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain [see Dosage and Administration (2.4), Drug Abuse and Dependence (9.3), and Nonclinical Toxicology (13.2)].

Additionally, 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 a full opioid agonist analgesic, including OLINVYK. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms [see Drug Interactions (7)].

5.14 Risks of Driving and Operating Machinery

OLINVYK may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of OLINVYK and know how they will react to the medication [see Patient Counseling Information (17)].

5.15 Patient-Controlled Analgesia (PCA)

Although self-administration of opioids by 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.

The following adverse reactions are described, or described in greater detail, in other sections:

• Addiction, Abuse, and Misuse [see Warnings and Precautions (5.1)]
• Life-threatening Respiratory Depression [see Warnings and Precautions (5.2)]
• Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.3)]
• Interactions with Benzodiazepines or Other CNS Depressants [see Warnings and Precautions (5.4)]
• Adrenal Insufficiency [see Warnings and Precautions (5.8)]
• Severe Hypotension [see Warnings and Precautions (5.9)]
• Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.11)]
• Seizures [see Warnings and Precautions (5.12)]
• Withdrawal [see Warnings and Precautions (5.13)]

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

A total of 1535 patients were treated with OLINVYK in controlled and open-label trials in patients with moderate to severe acute pain. Of these, 1181 patients received a total daily dose ≤27 mg and 354 patients received a total daily dose >27 mg during the first 24-hour treatment period. Among patients who received a daily dose of >27 mg, 198 patients received a daily dose between 27 mg and 40 mg, and 142 patients received a daily dose >40 mg.

The most common adverse drug reactions (≥10%) in controlled efficacy trials (Study 1 and Study 2) were nausea, vomiting, dizziness, headache, constipation, pruritus and hypoxia. Adverse reactions leading to discontinuation of OLINVYK were hypotension, hypoxia, nausea, hypoventilation, oxygen saturation decreased, alanine aminotransferase increased, aspartate aminotransferase increased, electrocardiogram QT prolongation, and urticaria. In two randomized, double-blind, placebo- and morphine-controlled studies, when stratified by 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 these same studies, discontinuation due to adverse reactions occurred in 5% of morphine-treated patients, and no placebo-treated patients. In an open-label safety study, discontinuation of OLINVYK 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.

In two randomized, double-blind, placebo- and morphine-controlled studies in patients with moderate to severe acute pain following either orthopedic surgery-bunionectomy (Study 1), or plastic surgery-abdominoplasty (Study 2), patients received one of three OLINVYK dosing regimens, a morphine-control regimen, or a volume−matched placebo−control regimen. All dosing regimens were administered via patient-controlled analgesia (PCA), allowing patients to individually titrate the dose available to an acceptable level of analgesia. Patients were treated for up to 48 hours in the bunionectomy study (Study 1), and for up to 24 hours in the abdominoplasty study (Study 2) [see Clinical Studies (14)]. 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 assigned treatment group; supplemental doses of 0.75 mg were permitted, beginning 1 hour after the loading dose, and hourly thereafter, as needed. The loading dose for the morphine treatment regimen was 4 mg; the demand dose was 1 mg; and supplemental doses of 2 mg were permitted, beginning 1 hour after the loading dose, and hourly thereafter, as needed. A lockout interval of 6 minutes was used for all PCA regimens.

In Study 1, a total of 136 patients received OLINVYK ≤27 mg/day, and 98 patients received OLINVYK >27 mg/day during the first 24 hours. In Study 2, a total of 180 patients received OLINVYK ≤27 mg/day, and 56 patients received OLINVYK >27 mg/day during the first 24 hours.

Table 1 and Table 2 list adverse drug reactions that were reported in ≥5% of OLINVYK-treated patients in each study, and that occurred at a frequency greater than placebo in at least one of the studies.

Table 3 lists adverse drug reactions that were reported in ≥5% of OLINVYK-treated patients for pooled Studies 1 and 2 stratified by total daily dose (≤27 mg/day or >27 mg/day).

These data are not an adequate basis for comparison of rates between the OLINVYK treatment group and the morphine treatment group. The OLINVYK and morphine dosing regimens studied are not considered equipotent.

^a Treatment Emergent Adverse Event

In an open-label safety study of patients with moderate to severe acute pain following a surgical procedure or due to a medical condition (Study 3), 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.

In Study 3, for the patients within the highest cumulative dose group (exposure >36 mg), the mean cumulative exposure was 67 mg (range: 37 mg to 224 mg) and the mean cumulative duration of exposure was 54 hours (range: 6 hours to 143 hours). The mean cumulative dose of OLINVYK administered to patients in the Study 3 was 30 mg over a mean cumulative duration of 29 hours. The most frequent condition treated in Study 3 was post-surgical acute pain, and included (in order of decreasing frequency): orthopedic, gynecologic, colorectal, general, plastic, urologic, neurologic (including spinal), bariatric, and cardiothoracic surgical procedures. In Study 3, 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.

In Study 3 (open-label), a total of 592 patients received OLINVYK ≤27 mg/day and 176 received OLINVYK >27 mg during the first 24 hours. Adverse drug reactions reported in ≥5% of patients receiving OLINVYK in Study 3, stratified by total daily dose (≤27 mg/day or >27 mg/day), are presented in Table 4.

Risk Summary

Prolonged use of opioid analgesics during pregnancy may result in neonatal opioid withdrawal syndrome [see Warnings and Precautions (5.3) and Clinical Considerations]. There are no available data on OLINVYK use in pregnant women to evaluate for a drug-associated risk of major birth defects and miscarriage.

In animal reproductive studies, oliceridine reduced live litter size at birth and increased postnatal pup mortality between birth and Postnatal Day 4 when administered intravenously to rats from organogenesis through weaning at doses producing clinically relevant plasma exposure. Oliceridine had no effect on embryo-fetal development in rats and rabbits when administered intravenously during organogenesis at doses producing plasma exposures 7 and 8 times the estimated plasma exposure at the maximum recommended human dose (MRHD) on an AUC basis, respectively (see Data).

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Clinical Considerations

Fetal/Neonatal Adverse Reactions

Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth.

Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high-pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see Warnings and Precautions (5.3)].

Labor or Delivery

Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. An opioid antagonist, such as naloxone, should be available for reversal of opioid induced respiratory depression in the neonate. OLINVYK is not recommended for use in pregnant women during and immediately prior to labor, when other analgesic techniques are more appropriate. Opioid analgesics can prolong labor through actions that temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilatation, which tends to shorten labor. Monitor neonates exposed to OLINVYK during labor for signs of excess sedation and respiratory depression.

Data

Animal Data

Oliceridine administered via continuous intravenous infusion during the period of embryofetal organogenesis at doses of 6, 12, or 24 mg/kg/day to pregnant rats from Gestation Day (GD) 6 to 20 and 1.5, 3, or 6 mg/kg/day to pregnant rabbits from GD 7 to 29 had no effect on embryonic development at exposures 7 (rats) to 8 times (rabbits) the estimated plasma exposure at the MRHD of 27 mg/day on an AUC basis. Maternal toxicity (reduced body weight gain) was observed at ≥12 mg/kg/day in rats and at 6 mg/kg/day in rabbits.

In a pre−and post−natal development study in rats, oliceridine administered via continuous intravenous infusion at doses of 0.6, 2.4, and 6.0 mg/kg/day from Gestation Day 6 through Lactation Day 21 resulted in reduced live litter size at birth at 1.5 times the estimated plasma exposure at the MRHD on an AUC basis and lower pup survival between birth and Postnatal Day 4 at 0.6 times the estimated plasma exposure at the MRHD on an AUC basis.

Risk Summary

It is not known whether oliceridine is present in human milk. The effects of oliceridine on a breastfeeding infant and on milk production have not been evaluated.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for OLINVYK and any potential adverse effects on the breastfed infant from OLINVYK or from the underlying maternal condition.

Clinical Considerations

Monitor infants exposed to OLINVYK through breast milk for excess sedation and respiratory depression. Withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic is stopped or when breastfeeding is stopped.

Infertility

Human Data

Chronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is not known whether these effects on fertility are reversible [see Adverse Reactions (6.1), Clinical Pharmacology (12.2)].

Animal Data

Oliceridine administered intravenously for 14 days prior to cohabitation and administered through GD15 caused prolonged estrous cycle lengths and decreased the number of implantations and viable embryos in female rats at doses producing plasma exposures ≥3 times the MRHD on an AUC basis [see Nonclinical Toxicology (13.1)].

The safety and effectiveness of OLINVYK in pediatric patients has not been established.

Controlled clinical studies of OLINVYK did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

Elderly patients (aged 65 years or older) may have increased sensitivity to OLINVYK. In general, use caution when selecting a dosage for an elderly patient, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.

Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after large initial doses were administered to patients who were not opioid-tolerant or when opioids were co-administered with other agents that depress respiration. Titrate the dosage of OLINVYK slowly in geriatric patients and monitor for signs of central nervous system and respiratory depression [see Warnings and Precautions (5.7)].

In patients with end-stage renal disease, there was no clinically significant change in oliceridine clearance. Therefore, dosage adjustment of OLINVYK in patients with renal impairment is not required [see Clinical Pharmacology (12.3)].

In patients with mild or moderate hepatic impairment, no adjustment of the initial dose is needed; however, these patients may require less frequent dosing. When using OLINVYK in patients with severe hepatic impairment, consider reducing the initial dose, and administer subsequent doses only after a careful review of the patient’s severity of pain and overall clinical status [see Clinical Pharmacology (12.3)].

8.8 Poor Metabolizers of CYP2D6 Substrates

In patients who are known or suspected to be poor CYP2D6 metabolizers, based on genotype or previous history/experience with other CYP2D6 substrates, less frequent dosing of OLINVYK may be required. These patients should be closely monitored, and subsequent doses should be based on the patient’s severity of pain and response to treatment. [See Warnings and Precautions (5.6), Clinical Pharmacology (12.5)].

OLINVYK contains oliceridine, a Schedule II controlled substance.

OLINVYK contains oliceridine, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxycodone, oxymorphone, and tapentadol. OLINVYK can be abused and is subject to misuse, abuse, addiction, and criminal diversion [see Warnings and Precautions (5.1)].

The abuse potential of oliceridine was evaluated in healthy, nondependent, recreational opioid users at doses of 1, 2, and 4 mg. Intravenous morphine was used as a positive control at doses of 10 and 20 mg. Statistically significant differences were observed between all doses of oliceridine and placebo on most subjective effects (e.g., Drug Liking VAS) and pupillometry endpoints (e.g., miosis). Intravenous administration of oliceridine demonstrated comparable subjective effects when compared to dose-matched levels of intravenously administered morphine.

All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.

Prescription abuse is the intentional, non-therapeutic use of a drug, even once, for its rewarding psychological or physiological effects.

Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence.

“Drug seeking” behavior is very common in persons with substance use disorders. Drug seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated “loss” of prescriptions, tampering of prescriptions, and reluctance to provide prior medical records or contact information for other treating health care provider(s). “Doctor shopping” (visiting multiple prescribers or healthcare prescribers to obtain additional prescriptions) is common among drug abusers and people suffering from untreated addiction. Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control.

Abuse and addiction are separate and distinct from physical dependence and tolerance. Healthcare providers should be aware that addiction in some individuals may not be accompanied by concurrent tolerance and symptoms of physical dependence. In addition, abuse of opioids can occur in the absence of true addiction.

OLINVYK injection, like other opioids, can be diverted for non-medical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity and frequency, and renewal requests, as required by law, is strongly advised.

Proper assessment of the patient, proper prescribing practices, periodic reevaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.

There were no reports of diversion of OLINVYK during the clinical development program.

Risk Specific to Abuse of OLINVYK Injection

Abuse of OLINVYK injection poses a risk of overdose and death. The risk is increased with concurrent use of OLINVYK with alcohol and other central nervous system depressants.

Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.

Both tolerance and physical dependence can develop during chronic opioid therapy.

Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose).

Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity (e.g., naloxone), mixed agonist/antagonist analgesics (e.g., pentazocine, butorphanol, nalbuphine), or partial agonists (e.g., buprenorphine). Physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage.

OLINVYK should not be abruptly discontinued in a physically-dependent patient [see Dosage and Administration (2.3)]. If OLINVYK is abruptly discontinued in a physically-dependent patient, a withdrawal syndrome may occur. Some or all of the following can characterize this syndrome: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other signs and symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate [see Nonclinical Toxicology (13.2)].

Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal signs [see Use in Specific Populations (8.1)].
