UBRELVY

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in labeling: Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Hypertension [see Warnings and Precautions ( 5.2 )] Raynaud’s Phenomenon [see Warnings and Precautions ( 5.3 )] The most common adverse reactions (at least 2% and greater than placebo) were nausea and somnolence.

The safety of UBRELVY was evaluated in 3,624 subjects who received at least one dose of UBRELVY. In two randomized, double-blind, placebo-controlled, Phase 3 trials in adult patients with migraine (Studies 1 and 2), a total of 1,439 patients received UBRELVY 50 mg or 100 mg [see Clinical Studies ( 14 )] . Of the UBRELVY-treated patients in these 2 studies, approximately 89% were female, 82% were White, 15% were Black, and 17% were of Hispanic or Latino ethnicity. The mean age at study entry was 41 years (range of 18-75 years). Long-term safety was assessed in 813 patients, dosing intermittently for up to 1 year in an open-label extension study. Patients were permitted to treat up to 8 migraines per month with UBRELVY. Of these 813 patients, 421 patients were exposed to 50 mg or 100 mg for at least 6 months, and 364 patients were exposed to these doses for at least one year, all of whom treated at least two migraine attacks per month, on average. In that study, 2.5% of patients were withdrawn from UBRELVY because of an adverse reaction. The most common adverse reaction resulting in discontinuation in the long-term safety study was nausea. Adverse reactions in Studies 1 and 2 are shown in Table 2.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Immune System Disorders: Hypersensitivity (e.g., anaphylaxis, dyspnea, facial or throat edema, rash, urticaria, and pruritus) [see Contraindications ( 4 ) and Warnings and Precautions ( 5.1 )] Vascular Disorders: Hypertension [see Warnings and Precautions ( 5.2 )] , Raynaud’s phenomenon [see Warnings and Precautions ( 5.3 )]

7 DRUG INTERACTIONS Strong CYP3A4 Inducers: Should be avoided as concomitant use will result in reduction of ubrogepant exposure. ( 2.2 , 7.2 ) For additional dose modifications for moderate or weak CYP3A4 inhibitors and inducers or BCRP and/or P-gp only inhibitors, refer to section 2.2 . ( 7.1 , 7.2 , 7.3 ) 7.1 CYP3A4 I nhibitors Co-administration of UBRELVY with ketoconazole, a strong CYP3A4 inhibitor, resulted in a significant increase in exposure of ubrogepant [see Clinical Pharmacology ( 12.3 ) ] . UBRELVY should not be used with strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin) [see Contraindication s ( 4 )] . Co-administration of UBRELVY with verapamil, a moderate CYP3A4 inhibitor, resulted in an increase in ubrogepant exposure [see Clinical Pharmacology ( 12.3 ) ] . Dose adjustment is recommended with concomitant use of UBRELVY and moderate CYP3A4 inhibitors (e.g., cyclosporine, ciprofloxacin, fluconazole, fluvoxamine, grapefruit juice) [see Dosage and Administration ( 2.2 )] . No dedicated drug interaction study was conducted with ubrogepant and weak CYP3A4 inhibitors. Dose adjustment is recommended with concomitant use of UBRELVY with weak CYP3A4 inhibitors [see Dosage and Administration ( 2.2 )] . 7.2 CYP3A4 I nducers Co-administration of UBRELVY with rifampin, a strong CYP3A4 inducer, resulted in a significant reduction in ubrogepant exposure [ s ee Clinical Pharmacology ( 12.3 ) ] . In patients taking strong CYP3A4 inducers (e.g., phenytoin, barbiturates, rifampin, St. John’s Wort), loss of ubrogepant efficacy is expected, and concomitant use should be avoided. Co-administration of UBRELVY with moderate or weak CYP3A4 inducers was not evaluated in a clinical study. Dose adjustment is recommended with concomitant use of UBRELVY and moderate or weak CYP3A4 inducers [see Dosage and Administration ( 2.2 )] . 7 .3 BCRP and / or P-gp Only Inhibitors Ubrogepant is a substrate of BCRP and P-gp efflux transporters. Use of BCRP and/or P-gp only inhibitors (e.g., quinidine, carvedilol, eltrombopag, curcumin) may increase the exposure of ubrogepant [ s ee Clinical Pharmacology ( 12.3 ) ] . Clinical drug interaction studies with inhibitors of these transporters were not conducted. Dose adjustment is recommended with BCRP and/or P-gp only inhibitors [see Dosage and Administration ( 2.2 ) ] .
