50 JL: can will create a transition slide? 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. 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. 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. 51

WARNINGS AND PRECAUTIONS • 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. • P r o f ound s e d a tion, re spi r a to r y d e p r e ssion, c om a , a nd d ea th m a y re sult f r om the c on c omit a nt use of OLINVYK with b e n z odi a z e pin e s or oth e r C NS d e p re ss a nts ( e .. g .., non - b e n z odi a z e pine s e d a tiv e s/ h y pnoti c s, a n x i o l y ti c s, t ra nquili z er s, mus c le re l a x a nts, g e n e ra l a n e sth e ti c s, a ntip s y c hoti c s, oth e r opioids, or a l c ohol ) .. B e ca u s e o f th e se r isks, re s er ve c o n c omit a nt p re s cr ibi n g of th e se d r u g s f o r use in p a ti e nts f or whom a lt er n a tive t rea tm e nt options a r e in a d e qu a t e , 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 m a y ca u s e s e v e r e h y po t e ns i o n, i n c l u d i n g or t h o s tatic h y po t e ns i o n a n d s yn c op e in a m b u lat o r y p atie n t s .. • T h e r e is i n c r ea s ed r i s k in p ati e n ts w ho s e a b ili t y to m a i n ta i n b l oo d pr e ssu r e h as a l r ea d y b een c o m pr o m i s ed b y a r e d u ced b l oo d v o l u m e o r c o n c u rr e n t a d m i n i s t r ati o n o f c e r tain C N S d e pr e ss a n t dru g s ( e .. g .. , phenothiazines or g e n e r al a n e s t h eti c s ).

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. The most common (incidence ≥10%) adverse reactions in Phase 3 controlled clinical trials were nausea, vomiting, dizziness, headache, constipation, pruritus, and hypoxia.
