Before treatment, evaluate for muscle pain or myopathy, and/or verify that females of reproductive potential are not pregnant. The recommended dosage is 80 mg orally once daily with or without food

Recommended Evaluation Before Initiating IQIRVO Before initiating IQIRVO: Evaluate for muscle pain or myopathy . Verify that females of reproductive potential are not pregnant prior to initiating treatment with IQIRVO [ see Warnings and Precautions , Use in Specific Populations (8.1 , 8.3) ]

Recommended Dosage and Administration The recommended dosage of IQIRVO is 80 mg taken orally once daily with or without food

Administration Modification for Bile Acid Sequestrants Administer IQIRVO at least 4 hours before or 4 hours after administering the bile acid sequestrant, or at as great an interval as possible .

Myalgia, Myopathy, and Rhabdomyolysis : Assess for muscle pain and myopathy prior to IQIRVO initiation. Consider periodic assessment (clinical exam, CPK measurement). Interrupt IQIRVO if there is new onset or worsening of muscle injury, or muscle pain. Fractures: The risk of fracture should be considered in the care of patients treated with IQIRVO. Apply current standards of care for assessing and maintaining bone health. Adverse Effects on Fetal and Newborn Development : May cause fetal harm. Verify that a female of reproductive potential is not pregnant prior to initiating IQIRVO. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. ( 5.3 , 8.1 , 8.3 ) Drug-Induced Liver Injury : Obtain clinical and laboratory assessments at treatment initiation and monitor thereafter according to routine patient management. Interrupt the treatment if liver tests worsen, or patients develop signs and symptoms consistent with clinical hepatitis. Consider permanent discontinuation if liver tests worsen after restarting IQIRVO. Hypersensitivity Reactions : If severe hypersensitivity reactions occur, permanently discontinue IQIRVO. If a mild or moderate hypersensitivity reaction occurs, interrupt IQIRVO and treat promptly. Monitor until signs and symptoms resolve. Biliary Obstruction : Avoid use in patients with complete biliary obstruction. If biliary obstruction is suspected, interrupt IQIRVO and treat as clinically indicated. 5.1 Myalgia, Myopathy, and Rhabdomyolysis Rhabdomyolysis resulting in acute kidney injury occurred in one IQIRVO-treated patient who had cirrhosis at baseline and was also taking a stable dose of an HMG-CoA reductase inhibitor (statin). Myalgia or myopathy, with or without CPK elevations, occurred in patients treated with IQIRVO alone or treated concomitantly with a stable dose of an HMG-CoA reductase inhibitor . Assess for myalgia and myopathy prior to IQIRVO initiation. Consider periodic assessment (clinical exam, CPK measurement) during treatment with IQIRVO, especially in those who have signs and symptoms of new onset or worsening of muscle pain or myopathy. Interrupt IQIRVO treatment if there is new onset or worsening of muscle pain, or myopathy, or rhabdomyolysis

Fractures Fractures occurred in 6% of IQIRVO-treated patients compared to no placebo-treated patients . Consider the risk of fracture in the care of patients treated with IQIRVO and monitor bone health according to current standards of care

Adverse Effects on Fetal and Newborn Development Based on findings from animal reproduction studies, IQIRVO may cause fetal harm when administered during pregnancy. Treatment of pregnant rats with elafibranor at maternal plasma drug exposures lower than or approximately equal to human exposure at the recommended dose resulted in stillbirths, reduced survival, decrease in pup body weight, and/or blue/black discoloration of the caudal section of body. For females of reproductive potential, verify that the patient is not pregnant prior to initiation of therapy. Advise females of reproductive potential to use effective non-hormonal contraceptives or add a barrier method when using hormonal contraceptives during treatment with IQIRVO and for 3 weeks following the last dose of IQIRVO

Drug-Induced Liver Injury Drug-induced liver injury (DILI) occurred in one patient who took IQIRVO 80 mg once daily and two patients who took IQIRVO at 1.5-times the recommended dosage. In one patient who developed DILI while taking IQIRVO at 1.5-times the recommended dosage, the clinical presentation was drug-induced autoimmune-like hepatitis (DI-ALH). The median time to onset of elevation in liver tests was 85 days (range: day 57 to 288). In Study 1, increases in transaminases (alanine aminotransferase [ALT] and aspartate aminotransferase [AST] ≥ 5× ULN) occurred in 6% of IQIRVO-treated patients compared to 6% of placebo-treated patients, and total bilirubin (TB) elevation (> 3× ULN) occurred in 2% of IQIRVO-treated patients compared to no placebo-treated patients . Obtain baseline clinical and laboratory assessments at treatment initiation with IQIRVO and monitor thereafter according to routine patient management. Interrupt IQIRVO treatment if liver tests (ALT, AST, TB, and/or alkaline phosphatase [ALP]) worsen, or the patient develops signs and symptoms consistent with clinical hepatitis (e.g., jaundice, right upper quadrant pain, eosinophilia). Consider permanent discontinuation if liver tests worsen after restarting IQIRVO

Hypersensitivity Reactions Hypersensitivity reactions have occurred in a clinical trial with IQIRVO at 1.5-times the recommended dosage. Three patients (0.2%) had rash or unspecified allergic reaction that occurred 2 to 30 days after IQIRVO initiation, with positive dechallenges and rechallenges. Hypersensitivity reactions resolved after discontinuation of IQIRVO and treatment with steroids and/or antihistamines. If a severe hypersensitivity reaction occurs, permanently discontinue IQIRVO. If a mild or moderate hypersensitivity reaction occurs, interrupt IQIRVO and treat promptly. Monitor the patient until signs and symptoms resolve. If a hypersensitivity reaction recurs after IQIRVO rechallenge, then permanently discontinue IQIRVO

Biliary Obstruction Avoid use of IQIRVO in patients with complete biliary obstruction. If biliary obstruction is suspected, interrupt IQIRVO and treat as clinically indicated .

Hormonal Contraceptives: Switch to effective non-hormonal contraceptives or add a barrier method when using hormonal contraceptives and for at least 3 weeks after last dose. HMG-CoA Reductase Inhibitors : Monitor for signs and symptoms of muscle injury. Rifampin: Monitor the biochemical response (e.g., ALP and bilirubin) when patients initiate rifampin during IQIRVO treatment. Bile Acid Sequestrants: Administer at least 4 hours before or 4 hours after taking a bile acid binding sequestrant, or at as great an interval as possible

Effects of IQIRVO on Other Drugs Table 3 includes clinically significant drug interactions affecting other drugs. Table 3: Clinically Significant Interactions Affecting Other Drugs Hormonal Contraceptives Clinical Impact IQIRVO is a weak CYP3A4 inducer . Co-administration of IQIRVO and hormonal contraceptives (e.g., birth control pills, skin patches, implant) may reduce the systemic exposure of progestin and ethinyl estradiol (CYP3A4 substrates), which may lead to contraceptive failure and/or an increase in breakthrough bleeding. Intervention Switch to effective non-hormonal contraceptives or add a barrier method when using hormonal contraceptives during treatment with IQIRVO and for at least 3 weeks after last dose . HMG-CoA Reductase Inhibitors Clinical Impact CPK elevation and/or myalgia occurred in patients on IQIRVO monotherapy. Co-administration of IQIRVO and HMG-CoA reductase inhibitors (statins) which have a risk of myalgia, can increase the risk of myopathy by a mechanism that has not been fully characterized . Intervention Monitor for signs and symptoms of muscle injury. Consider periodic assessment (clinical exam, CPK) during treatment. Interrupt IQIRVO treatment if there is new onset or worsening of muscle pain or myopathy

Effects of Other Drugs on IQIRVO Table 4 includes clinically significant drug interactions affecting IQIRVO. Table 4: Clinically Significant Interactions Affecting IQIRVO Rifampin Clinical Impact Co-administration of IQIRVO with rifampin, an inducer of metabolizing enzymes, may reduce the systemic exposure of elafibranor and its active metabolite via increased metabolism and may result in delayed or suboptimal biochemical response . Intervention Monitor the biochemical response (e.g., ALP and bilirubin) when patients initiate rifampin during treatment with IQIRVO. Bile Acid Binding Sequestrants Clinical Impact Bile acid sequestrants may interfere with the action of IQIRVO by reducing its absorption and systemic exposure, which may reduce IQIRVO efficacy. Intervention Administer IQIRVO at least 4 hours before or 4 hours after taking a bile acid binding sequestrant, or at as great an interval as possible .
