UBRELVY Tablet Ref.[10378] Active ingredients:

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 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 In that study, 2.5% of patients were withdrawn from UBRELVY because of an adverse reaction.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.

* Somnolence includes the adverse reaction-related terms sedation and fatigue.

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 Contraindications (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 [see 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 [see 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)].

Risk Summary

There are no adequate data on the developmental risk associated with the use of UBRELVY in pregnant women. In animal studies, adverse effects on embryofetal development were observed following administration of ubrogepant during pregnancy (increased embryofetal mortality in rabbits) or during pregnancy and lactation (decreased body weight in offspring in rats) at doses greater than those used clinically and which were associated with maternal toxicity (see Data).

In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The estimated rate of major birth defects (2.2%-2.9%) and miscarriage (17%) among deliveries to women with migraine are similar to rates reported in women without migraine.

Clinical Considerations

Disease-Associated Maternal and/or Embryo/Fetal Risk

Published data have suggested that women with migraine may be at increased risk of preeclampsia and gestational hypertension during pregnancy.

Data

Animal Data

Oral administration of ubrogepant (0, 1.5, 5, 25, 125 mg/kg/day) to pregnant rats during the period of organogenesis resulted in no adverse effects on embryofetal development. Plasma exposure (AUC) at the highest dose tested is approximately 45 times that in humans at the maximum recommended human dose (MRHD) of 200 mg/day.

In pregnant rabbits, ubrogepant (0, 15, 45, 75, or 250 mg/kg/day) was administered orally throughout organogenesis in two separate studies. In both studies, the highest dose tested (250 mg/kg/day) was associated with maternal toxicity. In the first study, ubrogepant produced abortion and increased embryofetal mortality in surviving litters at the high dose (250 mg/kg/day). In the second study, excessive maternal toxicity at the high dose (250 mg/kg/day) resulted in early termination and lack of fetal data for that dose group. Plasma exposure (AUC) at the highest no-effect dose (75 mg/kg/day) for adverse effects on embryofetal development in rabbit is approximately 8 times that in humans at the MRHD.

Oral administration of ubrogepant (0, 25, 60, or 160 mg/kg/day) to rats throughout gestation and lactation resulted in decreased body weight in offspring at birth and during the lactation period at the mid and high doses, which were associated with maternal toxicity. Plasma exposure (AUC) at the no-effect dose for adverse effects on pre- and postnatal development in rats (25 mg/kg/day) is approximately 15 times that in humans at the MRHD.

There are no data on the presence of ubrogepant in human milk, the effects of ubrogepant on the breastfed infant, or the effects of ubrogepant on milk production. In lactating rats, oral dosing with ubrogepant resulted in levels of ubrogepant in milk comparable to peak plasma concentrations. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for UBRELVY and any potential adverse effects on the breastfed infant from UBRELVY or from the underlying maternal condition.

Safety and effectiveness in pediatric patients have not been established.

In pharmacokinetic studies, no clinically significant pharmacokinetic differences were observed between elderly and younger subjects. Clinical studies of UBRELVY did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range.

The renal route of elimination plays a minor role in the clearance of ubrogepant [see Clinical Pharmacology (12.3)]. No dose adjustment is recommended for patients with mild or moderate renal impairment. Dose adjustment is recommended for patients with severe renal impairment (CLcr 15-29 mL/min) [see Dosage and Administration (2.2) and Clinical Pharmacology (12.3)]. Avoid use of UBRELVY in patients with end-stage renal disease (ESRD) (CLcr <15 mL/min).

In patients with pre-existing mild (Child-Pugh Class A), moderate (Child-Pugh Class B), or severe hepatic impairment (Child-Pugh Class C), ubrogepant exposure was increased by 7%, 50%, and 115%, respectively. No dose adjustment is recommended for patients with mild or moderate hepatic impairment. Dose adjustment for UBRELVY is recommended for patients with severe hepatic impairment [see Dosage and Administration (2.2)].
