What Is Elafibranor Used For?
1 INDICATIONS AND USAGE IQIRVO is indicated for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have had an inadequate response to UDCA, or as monotherapy in patients unable to tolerate UDCA. This indication is approved under accelerated approval based on reduction of alkaline phosphatase (ALP) [see Clinical Studies (14) ] . Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Ipsen Biopharmaceuticals, Inc. at 1-855-463-5127 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience 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 practice. The safety of IQIRVO is based on Study 1 consisting of 161 patients who were randomized to receive IQIRVO 80 mg (n=108) or placebo (n=53) once daily with a median duration of exposure during the double-blind period of 62 weeks (inter quartile range: 52, 84) [see Clinical Studies (14) ] . IQIRVO or placebo was administered in combination with UDCA in 95% of patients and as monotherapy in 5% of patients who were unable to tolerate UDCA. The most common adverse reaction leading to treatment discontinuation was increased CPK (4%). Common Adverse Reactions Table 1 presents common adverse reactions that occurred in Study 1. Table 1: Common Adverse Reactions Occurring During the Double-Blind Period in Adult Patients with PBC (Study 1) Included 8 patients (5%) who were intolerant to UDCA and initiated treatment as monotherapy: 6 patients (5%) in the IQIRVO arm and 2 patients (4%) in the placebo arm. Adverse Reaction Occurring in greater than or equal to 5% of patients in the IQIRVO treatment arm and at an incidence greater than or equal to 1% higher than in the placebo treatment arm.

Rhabdomyolysis and acute kidney injury (AKI) occurred in one IQIRVO-treated patient who had cirrhosis at baseline and was also on a stable dose of an HMG-CoA reductase inhibitor for a year. Median time to development of myalgia was 85.5 days (interquartile range: 29, 291). CPK elevation and/or myalgia occurred in patients on IQIRVO monotherapy as well as in patients who were concomitantly treated with an HMG-CoA reductase inhibitor.

Drug Interactions
7 DRUG INTERACTIONS 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. ( 7.1 ) HMG-CoA Reductase Inhibitors : Monitor for signs and symptoms of muscle injury. ( 5.1 , 7.1 ) Rifampin: Monitor the biochemical response (e.g., ALP and bilirubin) when patients initiate rifampin during IQIRVO treatment. ( 7.2 ) 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. ( 2.3 , 7.2 ) 7.1 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 [see Clinical Pharmacology (12.3) ] . 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 [see Warnings and Precautions (5.3) , Use in Specific Populations (8.1 , 8.3) ] . 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 [see Adverse Reactions (6.1) ] . 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 [see Warnings and Precautions (5.1) ] . 7.2 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 [see Clinical Pharmacology (12.3) ] . 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...

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on data from animal reproduction studies, IQIRVO may cause fetal harm when administered during pregnancy. Treatment of pregnant rats with elafibranor during organogenesis through lactation resulted in stillbirths, reduced survival, decrease in pup body weight, and/or blue/black discoloration of the caudal section of body, which occurred at maternal plasma drug exposures lower than or approximately equal to human exposure at the recommended dose ( see Data ). There are insufficient data from human pregnancies exposed to IQIRVO to allow an assessment of a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. The 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. Report pregnancies to Ipsen Pharmaceuticals, Inc. Adverse Event reporting line at 1-855-463-5127 and [https://www.ipsen.com/contact-us/]. Data Animal Data No effects on embryo-fetal development were observed in pregnant rats treated orally with up to 300 mg/kg/day elafibranor (15-times the recommended dose based on combined AUC [area under the plasma concentration-time curve] for elafibranor and GFT1007) during the period of organogenesis. No adverse effects on embryo-fetal development were observed in pregnant rabbits treated orally with doses up to 100 mg/kg/day elafibranor, which produced systemic exposures (combined AUC for elafibranor and GFT1007) during the period of organogenesis that were less than the human exposure. Administration of 300 mg/kg/day (3.9-times the recommended dose based on combined AUC for elafibranor and GFT1007) produced marked maternal toxicity, embryo-lethality, reduced fetal weight, and a low...
