skyclarys

Obtain alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, B-type natriuretic peptide (BNP), and lipid parameters prior to initiating SKYCLARYS and during treatment. ( 2.1 , 5.1 , 5.2 , 5.3 ) Recommended dosage is 150 mg (3 capsules) taken orally once daily. ( 2.2 ) Administer SKYCLARYS on an empty stomach, at least 1 hour before or 2 hours after eating. ( 2.2 ) Swallow SKYCLARYS capsules whole or open and sprinkle the entire contents of both halves of the capsule onto applesauce and mix. Do not crush or chew capsules. ( 2.2 ) Moderate and Severe Hepatic Impairment: The recommended dosage of SKYCLARYS is 100 mg once daily for patients with moderate hepatic impairment. If adverse reactions emerge, further reduce the dosage to 50 mg once daily. Avoid use in patients with severe hepatic impairment. ( 2.5 , 8.6 , 12.3 ) 2.1 Recommended Testing Before Initiating SKYCLARYS and Monitoring to Assess Safety Obtain ALT, AST, bilirubin, BNP, and lipid parameters prior to initiating SKYCLARYS and during treatment [see Warnings and Precautions ( 5.1 , 5.2 , 5.3 )] . 2.2 Recommended Dosage The recommended dosage of SKYCLARYS is 150 mg (3 capsules) taken orally once daily. Administer SKYCLARYS on an empty stomach, at least 1 hour before or 2 hours after eating [see Clinical Pharmacology ( 12.3 )]. Swallow SKYCLARYS capsules whole. Do not crush or chew. For patients…

The following clinically significant adverse reactions are described in greater detail in other labeling sections: Elevation of aminotransferases [see Warnings and Precautions ( 5.1 )] Elevation of BNP [see Warnings and Precautions ( 5.2 )] Lipid abnormalities [see Warnings and Precautions ( 5.3 )] Most common adverse reactions (incidence ≥20% and greater than placebo) are elevated liver enzymes (AST/ALT), headache, nausea, abdominal pain, fatigue, diarrhea, and musculoskeletal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Biogen at 1-844-987-3224- 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 with rates in clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety of SKYCLARYS 150 mg once daily has been evaluated in 165 patients with Friedreich's ataxia, including 137 patients exposed for at least 48 weeks, and 125 patients exposed for at least 96 weeks. The most common adverse reactions in Study 1 (≥20% and greater than placebo) were elevated liver enzymes (AST/ALT), headache, nausea, abdominal pain, fatigue, diarrhea, and musculoskeletal pain. Table 3 shows the adverse reactions that occurred in 10% or more of patients…

Moderate or Strong CYP3A4 Inhibitors: Avoid concomitant use. Consider SKYCLARYS dosage reduction with monitoring if use is unavoidable. ( 2.4 , 7.1 ) Moderate or Strong CYP3A4 Inducers: Avoid concomitant use. ( 7.1 ) 7.1 Effect of Other Drugs on SKYCLARYS CYP3A4 Inhibitors Omaveloxolone is a CYP3A4 substrate. Concomitant use of SKYCLARYS with moderate or strong CYP3A4 inhibitors is expected to result in clinically significant increased exposure of omaveloxolone [see Clinical Pharmacology ( 12.3 )], which may increase the risk of adverse reactions. Avoid concomitant use of SKYCLARYS with moderate or strong CYP3A4 inhibitors. If use cannot be avoided, dosage modifications are recommended [see Dosage and Administration ( 2.4 )]. CYP3A4 Inducers Omaveloxolone is a CYP3A4 substrate. Concomitant use of SKYCLARYS with moderate or strong CYP3A4 inducers is expected to result in clinically significant decreased exposure of omaveloxolone [see Clinical Pharmacology ( 12.3 )] , which may reduce the effectiveness of SKYCLARYS. Avoid concomitant use of SKYCLARYS with moderate or strong CYP3A4 inducers. 7.2 Effect of SKYCLARYS on Other Drugs CYP3A4 and CYP2C8 Substrates Omaveloxolone is a weak inducer of CYP3A4 and CYP2C8. Concomitant use with SKYCLARYS can reduce the exposure of CYP3A4 and CYP2C8 substrates which may reduce the activity of these substrates [see Clinical Pharmacology ( 12.3 )] . Refer to the prescribing information of substrates of CYP3A4 and CYP2C8 for dosing instructions if used concomitantly with SKYCLARYS and monitor for lack of efficacy of the concomitant treatment. Hormonal Contraceptives Omaveloxolone is a weak CYP3A4 inducer [see Clinical Pharmacology ( 12.3 )] . Concomitant use with SKYCLARYS may reduce the efficacy of hormonal contraceptives. Advise patients to avoid concomitant use with combined hormonal contraceptives (e.g., pill, patch, ring), implants, and progestin only pills [see Use in Specific Populations ( 8.3 )] .
