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 [see Adverse Reactions (6.1)].
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 occurred in 6% of IQIRVO-treated patients compared to no placebo-treated patients [see Adverse Reactions (6.1)].
Consider the risk of fracture in the care of patients treated with IQIRVO and monitor bone health according to current standards of care.
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 [see Drug Interactions (7.1), Use in Specific Populations (8.1, 8.3)].
Drug-induced liver injury (DILI) occurred in one patient who took IQIRVO 80 mg once daily [see Adverse Reactions (6.1)] 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 druginduced 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] ≥ 5x ULN) occurred in 6% of IQIRVO-treated patients compared to 6% of placebotreated patients, and total bilirubin (TB) elevation (>3x 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 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.
Avoid use of IQIRVO in patients with complete biliary obstruction. If biliary obstruction is suspected, interrupt IQIRVO and treat as clinically indicated [see Adverse Reactions (6.1)].
The following clinically significant adverse reactions are described elsewhere in the labeling:
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%).
Table 1 presents common adverse reactions that occurred in Study 1.

c Weight gain, abdominal pain, muscle pain, fracture, and rash include other related terms.
Muscle injury included rhabdomyolysis, CPK elevation with or without myalgia, and myopathy. 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.
Table 2 presents the frequency of muscle injury related adverse reactions in Study 1.

Fractures occurred in 6% (n=7) of IQIRVO-treated patients compared to no placebo-treated patients. The median time to fracture after receiving IQIRVO was 122 days (interquartile range: 48, 258).
Additional adverse reactions that occurred more frequently in the IQIRVO-treated patients compared to placebo, but in less 5% of patients included dizziness, gastroenteritis, increased blood creatinine, and anemia.
New onset of cholelithiasis was detected in 3 (3%) IQIRVO-treated patients compared to no placebo-treated patients. The three IQIRVO-treated patients were taking UDCA concomitantly. An additional patient who had gallstones at baseline developed cholecystitis requiring cholecystectomy.
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)]. |
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 possible [see Dosage and Administration (2.3)]. |
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.

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 incidence of fetal malformations. Variations in ossification of distal limb bones occurred at 100 mg/kg/day, which was associated with strong signs of maternal toxicity (e.g., body weight loss).
A pre- and postnatal development study was performed using oral administration of 10, 30, or 100 mg/kg/day elafibranor in female rats during organogenesis through lactation. All doses produced a reduction in pup survival (during postnatal days 1-4 at 100 mg/kg/day and postnatal days 5-21 at 10 mg/kg/day and higher), a decrease in pup body weight (dose-dependent, up to -28% on postnatal day 1), blue/black discoloration of the caudal section of body, and developmental delays based on evaluation of physical landmarks and functional tests. The developmental delays were likely caused by the decrease in body weight. Adverse effects in the offspring occurred at maternal exposures at or above 0.6-times the recommended dose based on combined AUC for elafibranor and GFT1007. Stillbirths were observed in the 30 and 100 mg/kg/day groups (1.3 and 4.9-times the recommended dose, respectively, based on combined AUC for elafibranor and GFT1007). Aortic or iliac arterial thrombosis was found in decedent pups from females treated with 30 or 100 mg/kg/day. The surviving adult offspring showed no effects on learning and memory, reflex development, or reproductive capability.
There are no data available on the presence of elafibranor or its metabolites in human or animal milk, or on effects of the drug on the breastfed infant or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed infant, advise patients not to breastfeed during treatment with IQIRVO, and for 3 weeks after the last dose.
Based on animal data, IQIRVO may cause fetal harm when administered during pregnancy [see Use in Specific Populations (8.1)].
For females of reproductive potential, verify that the patient is not pregnant prior to initiating IQIRVO.
Advise females of reproductive potential to use effective contraception (non-hormonal) or add a barrier method of contraception when using hormonal contraceptives during treatment with IQIRVO and for 3 weeks after the last dose.
The safety and effectiveness of IQIRVO have not been established in pediatric patients.
Of the 108 IQIRVO-treated patients with PBC, 25 (23%) were 65 years of age and older, while 1 (1%) was 75 years of age and older. No overall differences in effectiveness of IQIRVO has been observed in patients 65 years of age and older compared to younger adult patients. In healthy elderly subjects (age range 75-80 years), mean systemic exposure (AUC) of elafibranor and the major active metabolite, GFT1007 was 23% and 52% higher, respectively, than those in healthy young subjects (age range 26 to 42 years).
No dosage adjustment for patients 65 years of age and older is necessary. However, because of limited clinical experience with IQIRVO in patients older than 75 years old, closer monitoring of adverse events in patients older than 75 years is recommended [see Clinical Pharmacology (12.3)].
The recommended dosage in patients with mild, moderate, or severe renal impairment is the same as in patients with normal kidney function [see Clinical Pharmacology (12.3)].
No dosage adjustment is recommended for patients with mild hepatic impairment (Child-Pugh A) [see Clinical Pharmacology (12.3)].
The safety and efficacy of IQIRVO in patients with decompensated cirrhosis have not been established. Use of IQIRVO is not recommended in patients who have or develop decompensated cirrhosis (e.g., ascites, variceal bleeding, hepatic encephalopathy). Monitor patients with cirrhosis for evidence of decompensation. Consider discontinuing IQIRVO if the patient progresses to moderate or severe hepatic impairment (Child-Pugh B or C).
