( 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 who are unable to swallow whole capsules: SKYCLARYS capsules may be opened and the entire contents of both halves of the capsule sprinkled onto 2 tablespoons (30 mL) of applesauce [see Clinical Pharmacology ( 12.3 )] . Stir the mixture until homogenous. Swallow all the drug/applesauce mixture immediately. Do not store the mixture for future use. Contents of the SKYCLARYS capsules should not be mixed with milk or orange juice. Not for enteral feeding tube administration. 2.3 Missed Doses If a dose of SKYCLARYS is missed, take the next dose at its scheduled time the following day. A double dose should not be taken to make up for a missed dose. 2.4 Recommendations for Concomitant Use with Strong or Moderate CYP3A4 Inhibitors and Inducers The recommended dosage for concomitant use of SKYCLARYS with cytochrome P450 (CYP) 3A4 inhibitors and inducers are described in Table 1 [see Drug Interactions ( 7.1 ) and Clinical Pharmacology ( 12.3 )]. Table 1: Recommended Dosage of SKYCLARYS with Concomitant Use of CYP3A4 Inhibitors and Inducers Concomitant Drug Class Dosage Strong CYP3A4 inhibitor Recommended to avoid concomitant use. If coadministration cannot be avoided: Reduce the dosage of SKYCLARYS to 50 mg once daily with close monitoring for adverse reactions. If adverse reactions emerge, coadministration with strong CYP3A4 inhibitors should be discontinued. Moderate CYP3A4 inhibitor Recommended to avoid concomitant use. If coadministration cannot be avoided: Reduce the dosage of SKYCLARYS to 100 mg once daily with close monitoring for adverse reactions. If adverse reactions emerge, further reduce the dosage of SKYCLARYS to 50 mg once daily. Strong or Moderate CYP3A4 inducer Recommended to avoid concomitant use. 2.5 Recommended Dosage for Patients with Hepatic Impairment The recommended dosage for patients with hepatic impairment are described in Table 2 [see Use in Specific Populations ( 8.6 )] . Table 2: Recommended Dosage in Patients with Hepatic Impairment Impairment Classification (Child-Pugh) Dosage Severe (Child-Pugh Class C) Avoid use Moderate (Child-Pugh Class B) 100 mg once daily with close monitoring for adverse reactions Consider lowering to 50 mg once daily if adverse reactions emerge Mild (Child-Pugh Class A) 150 mg once daily

WARNINGS AND PRECAUTIONS Elevation of Aminotransferases: Monitor ALT, AST, and total bilirubin prior to initiation, every month for the first 3 months of treatment, and periodically thereafter. ( 2.1 , 5.1 ) Elevation of B-type Natriuretic Peptide (BNP): Advise patients of signs and symptoms of fluid overload. ( 2.1 , 5.2 ) Lipid Abnormalities: Monitor cholesterol periodically during treatment. ( 2.1 , 5.3 ) 5.1 Elevation of Aminotransferases Treatment with SKYCLARYS can cause an elevation in hepatic transaminases (ALT and AST). In Study 1 [see Clinical Studies ( 14 )] , the incidence of elevations of ALT or AST above 5 times and 3 times the upper limit of normal (ULN) was 16% and 31%, respectively, in patients treated with SKYCLARYS. There were no cases of concomitant elevation of transaminases and total bilirubin observed in Study 1. Maximum increases in ALT and AST occurred within 12 weeks after starting SKYCLARYS. Increases in serum aminotransferases were generally asymptomatic and reversible following discontinuation of SKYCLARYS. Patients with clinically significant liver disease were excluded from Study 1. Monitor ALT, AST, and total bilirubin prior to initiation of SKYCLARYS, every month for the first 3 months of treatment, and periodically thereafter. If transaminases increase to levels greater than 5 times the ULN, or greater than 3 times the ULN with evidence of liver dysfunction (e.g., elevated bilirubin), immediately discontinue SKYCLARYS and repeat liver function tests as soon as possible. If transaminase levels stabilize or resolve, SKYCLARYS may be reinitiated with an appropriate increased frequency of monitoring of liver function [see Adverse Reactions ( 6.1 ) and Use in Specific Populations ( 8.6 )]. 5.2 Elevation of B-Type Natriuretic Peptide Treatment with SKYCLARYS can cause an increase in BNP, a marker of cardiac function. In Study 1, a total of 14% of patients treated with SKYCLARYS had an increase from baseline in BNP and a BNP above the ULN (100 pg/mL), compared to 4% of patients who received placebo. The incidence of elevation of BNP above 200 pg/mL was 4% in patients treated with SKYCLARYS. Cardiomyopathy and cardiac failure are common in patients with Friedreich's ataxia. Patients were excluded from Study 1 if they had BNP levels > 200 pg/mL prior to study entry, or a history of clinically significant left-sided heart disease and/or clinically significant cardiac disease, with the exception of mild to moderate cardiomyopathy associated with Friedreich's ataxia [see Adverse Reactions ( 6.1 )]. Whether the elevations in BNP in Study 1 are related to SKYCLARYS or cardiac disease associated with Friedreich's ataxia is unclear. Elevations in BNP may indicate cardiac failure and should prompt an evaluation of cardiac function. Check BNP prior to initiation of SKYCLARYS. Monitor patients for the signs and symptoms of fluid overload, such as sudden weight gain (3 pounds or more of weight gain in one day, or 5 pounds or more of weight gain in a week), peripheral edema, palpitations, and shortness of breath. If signs and symptoms of fluid overload develop, worsen, or require hospitalization, evaluate BNP and cardiac function, and manage appropriately. Management of fluid overload and heart failure may require discontinuation of SKYCLARYS. 5.3 Lipid Abnormalities Treatment with SKYCLARYS can cause changes in cholesterol. In Study 1, 29% of patients treated with SKYCLARYS reported elevated cholesterol above ULN at one or more time points. Mean increases were observed within 2 weeks of initiation of SKYCLARYS and returned to baseline within 4 weeks of discontinuing treatment. A total of 16% of patients treated with SKYCLARYS had an increase in low-density lipoprotein cholesterol (LDL-C) from baseline, compared to 8% of patients who received placebo. The mean increase in LDL-C for all SKYCLARYS-treated patients was 23.5 mg/dL at 48 weeks. A total of 6% of patients treated with SKYCLARYS had decreases in high-density lipoprotein cholesterol (HDL-C) from baseline compared to 4% of patients who received placebo. The mean decrease in HDL-C for all SKYCLARYS-treated patients was 5.3 mg/dL at 48 weeks. Assess lipid parameters prior to initiation of SKYCLARYS and monitor periodically during treatment. Manage lipid abnormalities according to clinical guidelines.

CONTRAINDICATIONS None. None. ( 4 )

Mechanism of Action The precise mechanism by which omaveloxolone exerts its therapeutic effect in patients with Friedreich's ataxia is unknown. Omaveloxolone has been shown to activate the Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway in vitro and in vivo in animals and humans. The Nrf2 pathway is involved in the cellular response to oxidative stress.
