Acute Treatment of Migraine The safety of NURTEC ODT for the acute treatment of migraine in adults has been evaluated in a randomized, double-blind, placebo-controlled trial (Study 1) in 682 patients with migraine who received one 75 mg dose of NURTEC ODT [see Clinical Studies (14) ] . Approximately 85% were female, 74% were White, 21% were Black, and 17% were Hispanic or Latino. The mean age at study entry was 40 years (range 18-75 years of age). Long-term safety was assessed in an open-label extension study using a different oral dosage form of rimegepant. That study evaluated 1,798 patients, dosing intermittently for up to one year, including 1,131 patients who were exposed to rimegepant 75 mg for at least 6 months, and 863 who were exposed for at least one year, all of whom treated an average of at least two migraine attacks per month. The most common adverse reaction in Study 1 was nausea (2% in patients who received NURTEC ODT compared to 0.4% of patients who received placebo). Hypersensitivity, including dyspnea and severe rash, occurred in less than 1% of patients treated with NURTEC ODT [see Contraindications (4) and Warnings and Precautions (5.1) ] . Preventive Treatment of Episodic Migraine The safety of NURTEC ODT for the preventive treatment of episodic migraine in adults has been established in a randomized, double-blind, placebo-controlled trial with an open-label extension (Study 2) using a different oral dosage form of rimegepant [see Clinical Studies (14) ] . In the 12-week, double-blind treatment period, 370 patients with migraine received one 75 mg dose of rimegepant every other day . Approximately 81% were female, 80% were White, 17% were Black, and 28% were Hispanic or Latino. The mean age at study entry was 41 years (range 18-74 years of age). Long-term safety was assessed in an open-label extension study that included 603 patients who were treated for up to one year. Overall, 527 patients were exposed to rimegepant 75 mg for at least 6 months, and 311 were exposed for at least one year. The most common adverse reactions (occurring in at least 2% of rimegepant-treated patients and at a frequency of at least 1% higher than placebo) in Study 2 were nausea (2.7% in patients who received rimegepant compared with 0.8% of patients who received placebo) and abdominal pain/dyspepsia (2.4% in patients who received rimegepant compared with 0.8% of patients who received placebo).

1 INDICATIONS AND USAGE NURTEC ODT is a calcitonin gene-related peptide receptor antagonist indicated for the: • acute treatment of migraine with or without aura in adults ( 1.1 ) • preventive treatment of episodic migraine in adults ( 1.2 ) 1.1 Acute Treatment of Migraine NURTEC ODT is indicated for the acute treatment of migraine with or without aura in adults . 1.2 Preventive Treatment of Episodic Migraine NURTEC ODT is indicated for the preventive treatment of episodic migraine in adults.

10 OVERDOSAGE There is limited clinical experience with NURTEC ODT overdosage. Treatment of an overdose of NURTEC ODT should consist of general supportive measures including monitoring of vital signs and observation of the clinical status of the patient. No specific antidote for the treatment of rimegepant overdose is available. Rimegepant is unlikely to be significantly removed by dialysis because of high serum protein binding [see Clinical Pharmacology (12.3) ] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Rimegepant is a calcitonin gene-related peptide receptor antagonist. 12.2 Pharmacodynamics The relationship between pharmacodynamic activity and the mechanism(s) by which rimegepant exerts its clinical effects is unknown. No clinically relevant differences in resting blood pressure were observed when rimegepant was concomitantly administered with sumatriptan (12 mg subcutaneous, given as two 6 mg doses separated by one hour) compared with sumatriptan alone to healthy volunteers. Cardiac Electrophysiology At a single dose 4 times the recommended dose, rimegepant does not prolong the QT interval to any clinically relevant extent. 12.3 Pharmacokinetics Absorption Following oral administration of NURTEC ODT, rimegepant is absorbed with the maximum concentration at 1.5 hours. The absolute oral bioavailability of rimegepant is approximately 64%. Effects of Food Following administration of NURTEC ODT under fed conditions with a high-fat or low-fat meal, T max was delayed by approximately 1 to 1.5 hours. A high-fat meal reduced C max by 42 to 53% and AUC by 32 to 38%. A low-fat meal reduced C max by 36% and AUC by 28%. NURTEC ODT was administered without regard to food in clinical safety and efficacy studies. The impact of the reduction in rimegepant exposure because of administration with food on its efficacy is unknown. Distribution The steady state volume of distribution of rimegepant is 120 L. Plasma protein binding of rimegepant is approximately 96%. Elimination Metabolism Rimegepant is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C9. Rimegepant is the primary form (~77%) with no major metabolites (i.e., > 10%) detected in plasma. Excretion The elimination half-life of rimegepant is approximately 11 hours in healthy subjects. Following oral administration of [ 14 C]-rimegepant to healthy male subjects, 78% of the total radioactivity was recovered in feces and 24% in urine. Unchanged rimegepant is the major single component in excreted feces (42%) and urine (51%). Specific Populations Renal Impairment In a dedicated clinical study comparing the pharmacokinetics of rimegepant in subjects with mild (estimated creatinine clearance [CLcr] 60-89 mL/min), moderate (CLcr 30-59 mL/min), and severe (CLcr 15-29 mL/min) renal impairment to that with normal subjects (healthy matched control), the exposure of rimegepant following single 75 mg dose was approximately 40% higher in subjects with moderate renal impairment. However, there was no clinically meaningful difference in the exposure of rimegepant in subjects with severe renal impairment compared to subjects with normal renal function (CLcr >= 90 mL/min). NURTEC ODT has not been studied in patients with end-stage renal disease (CLcr < 15 mL/min) [see Use in Specific Populations (8.7) ]. Hepatic Impairment In a dedicated clinical study comparing the pharmacokinetics of rimegepant in subjects with mild, moderate, and severe hepatic impairment to that with normal subjects (healthy matched control), the exposure of rimegepant (C max and AUC) following single 75 mg dose was approximately 2-fold higher in subjects with severe impairment (Child-Pugh class C). There were no clinically meaningful differences in the exposure of rimegepant in subjects with mild (Child-Pugh class A) and moderate hepatic impairment (Child-Pugh class B) compared to subjects with normal hepatic function [see Use in Specific Populations (8.6) ]. Other Specific Populations No clinically significant differences in the pharmacokinetics of rimegepant were observed based on age, sex, race/ethnicity, body weight, or CYP2C9 genotype [see Clinical Pharmacology (12.5) ]. Drug Interaction Studies In Vitro Studies • Enzymes Rimegepant is a substrate of CYP3A4 and CYP2C9 (see In Vivo Studies ). Rimegepant is not an inhibitor of CYP1A2, 2B6, 2C9, 2C19, 2D6, or UGT1A1 at clinically relevant concentrations. However, rimegepant is a weak inhibitor of CYP3A4 with time-dependent inhibition. Rimegepant is not an inducer of CYP1A2, CYP2B6, or CYP3A4 at clinically relevant concentrations. • Transporters Rimegepant is a substrate of P-gp and BCRP (see In Vivo Studies ) . Rimegepant is not a substrate of OATP1B1 or OATP1B3. Considering its low renal clearance, rimegepant was not evaluated as a substrate of the OAT1, OAT3, OCT2, MATE1, or MATE2-K. Rimegepant is not an inhibitor of P-gp, BCRP, OAT1, or MATE2-K at clinically relevant concentrations. It is a weak inhibitor of OATP1B1 and OAT3. Rimegepant is an inhibitor of OATP1B3, OCT2, and MATE1. In a dedicated interaction study, concomitant administration of 75 mg rimegepant at steady state with metformin, a MATE1 transporter substrate, at steady state resulted in no clinically significant impact on either metformin pharmacokinetics or on glucose utilization. No clinical drug interactions are expected for NURTEC ODT with OATP1B3 or OCT2, at clinically relevant concentrations. In Vivo Studies CYP3A4 Inhibitors In a dedicated drug interaction study, concomitant administration of 75 mg rimegepant (single dose) with itraconazole, a strong CYP3A4 inhibitor, at steady state resulted in increased exposures of rimegepant (AUC by 4-fold and C max by ~1.5-fold) [see Drug Interactions (7.1) ]. No dedicated drug interaction study was conducted to assess the effect of concomitant administration of a weak inhibitor of CYP3A4 on the pharmacokinetics of rimegepant. The concomitant administration of rimegepant with a moderate inhibitor of CYP3A4 may increase rimegepant exposures (AUC) by less than 2-fold [see Drug Interactions (7.1) ]. Concomitant administration of rimegepant with a weak inhibitor of CYP3A4 is not expected to have a clinically significant impact on rimegepant exposures. CYP3A Inducers In a dedicated drug interaction study, concomitant administration of 75 mg rimegepant (single dose) with rifampin, a strong CYP3A4 inducer, at steady state resulted in decreased exposures of rimegepant (AUC by 80% and C max by 64%), which may lead to loss of efficacy [see Drug Interactions (7.2) ] . No dedicated drug interaction study was conducted to assess the effect of concomitant administration of a moderate or weak inducer of CYP3A4 on the pharmacokinetics of rimegepant . Since rimegepant is a moderately sensitive substrate for CYP3A4, drugs that are moderate inducers of CYP3A4 can also cause significant reduction in rimegepant exposure resulting in loss of efficacy [see Drug Interactions (7.2) ] . Clinically significant interaction is not expected with concomitant administration of weak inducers of CYP3A4 and rimegepant. CYP2C9 Inhibitors In a dedicated drug interaction study, concomitant administration of 75 mg rimegepant (single dose) with fluconazole, a combined moderate CYP3A4 and CYP2C9 inhibitor, resulted in increased exposures of rimegepant (AUC by 1.8-fold) with no relevant effect on C max . Rimegepant is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C9. Increase in the exposure of rimegepant can be attributed to combined inhibition of CYP2C9 and CYP3A4 with fluconazole administration suggesting a minor contribution from CYP2C9. Thus, CYP2C9 inhibition alone is not expected to significantly affect rimegepant exposures. P-gp and BCRP Inhibitors In a dedicated drug interaction study, concomitant administration of NURTEC ODT with cyclosporine (a potent P-gp and BCRP inhibitor) and with quinidine (a potent P-gp inhibitor) resulted in an increase of similar magnitude in rimegepant exposure (AUC and C max by 1.6 and 1.4 fold with cyclosporine, and by 1.6 and 1.7 fold with quinidine, respectively) [see Drug Interactions (7.3) ]. Therefore, concomitant administration of NURTEC ODT with BCRP inhibitors is not expected to have a clinically significant impact on rimegepant exposures. Other Drugs: No significant pharmacokinetic interactions were observed when rimegepant was concomitantly administered with oral contraceptives (norelgestromin, ethinyl estradiol), midazolam (a sensitive CYP3A4 substrate), metformin (a MATE1 substrate), or sumatriptan [see Clinical Pharmacology (12.2) ]. 12.5 Pharmacogenomics CYP2C9 activity is reduced in individuals with genetic variants such as the CYP2C9*2 and CYP2C9*3 alleles. Rimegepant C max and AUC 0-inf were similar in CYP2C9 intermediate metabolizers (i.e., *1/*2, *2/*2, *1/*3, n=43) as compared to normal metabolizers (i.e., *1/*1, N=72). Adequate PK data are not available from CYP2C9 poor metabolizers (i.e., *2/*3). Since the contribution of CYP2C9 to rimegepant metabolism is considered minor, CYP2C9 polymorphism is not expected to significantly affect its exposure.

12.1 Mechanism of Action Rimegepant is a calcitonin gene-related peptide receptor antagonist.

12.2 Pharmacodynamics The relationship between pharmacodynamic activity and the mechanism(s) by which rimegepant exerts its clinical effects is unknown. No clinically relevant differences in resting blood pressure were observed when rimegepant was concomitantly administered with sumatriptan (12 mg subcutaneous, given as two 6 mg doses separated by one hour) compared with sumatriptan alone to healthy volunteers.

Specific Populations Renal Impairment In a dedicated clinical study comparing the pharmacokinetics of rimegepant in subjects with mild (estimated creatinine clearance [CLcr] 60-89 mL/min), moderate (CLcr 30-59 mL/min), and severe (CLcr 15-29 mL/min) renal impairment to that with normal subjects (healthy matched control), the exposure of rimegepant following single 75 mg dose was approximately 40% higher in subjects with moderate renal impairment. However, there was no clinically meaningful difference in the exposure of rimegepant in subjects with severe renal impairment compared to subjects with normal renal function (CLcr >= 90 mL/min). NURTEC ODT has not been studied in patients with end-stage renal disease (CLcr < 15 mL/min) [see Use in Specific Populations (8.7) ]. Hepatic Impairment In a dedicated clinical study comparing the pharmacokinetics of rimegepant in subjects with mild, moderate, and severe hepatic impairment to that with normal subjects (healthy matched control), the exposure of rimegepant (C max and AUC) following single 75 mg dose was approximately 2-fold higher in subjects with severe impairment (Child-Pugh class C).

In a dedicated interaction study, concomitant administration of 75 mg rimegepant at steady state with metformin, a MATE1 transporter substrate, at steady state resulted in no clinically significant impact on either metformin pharmacokinetics or on glucose utilization. No clinical drug interactions are expected for NURTEC ODT with OATP1B3 or OCT2, at clinically relevant concentrations. In Vivo Studies CYP3A4 Inhibitors In a dedicated drug interaction study, concomitant administration of 75 mg rimegepant (single dose) with itraconazole, a strong CYP3A4 inhibitor, at steady state resulted in increased exposures of rimegepant (AUC by 4-fold and C max by ~1.5-fold) [see Drug Interactions (7.1) ]. No dedicated drug interaction study was conducted to assess the effect of concomitant administration of a weak inhibitor of CYP3A4 on the pharmacokinetics of rimegepant. The concomitant administration of rimegepant with a moderate inhibitor of CYP3A4 may increase rimegepant exposures (AUC) by less than 2-fold [see Drug Interactions (7.1) ]. Concomitant administration of rimegepant with a weak inhibitor of CYP3A4 is not expected to have a clinically significant impact on rimegepant exposures. CYP3A Inducers In a dedicated drug interaction study, concomitant administration of 75 mg rimegepant (single dose) with rifampin, a strong CYP3A4 inducer, at steady state resulted in decreased exposures of rimegepant (AUC by 80% and C max by 64%), which may lead to loss of efficacy [see Drug Interactions (7.2) ] . No dedicated drug interaction study was conducted to assess the effect of concomitant administration of a moderate or weak inducer of CYP3A4 on the pharmacokinetics of rimegepant . Since rimegepant is a moderately sensitive substrate for CYP3A4, drugs that are moderate inducers of CYP3A4 can also cause significant reduction in rimegepant exposure resulting in loss of efficacy [see Drug Interactions (7.2) ] . Clinically significant interaction is not expected with concomitant administration of weak inducers of CYP3A4 and rimegepant. CYP2C9 Inhibitors In a dedicated drug interaction study, concomitant administration of 75 mg rimegepant (single dose) with fluconazole, a combined moderate CYP3A4 and CYP2C9 inhibitor, resulted in increased exposures of rimegepant (AUC by 1.8-fold) with no relevant effect on C max . Rimegepant is primarily metabolized by CYP3A4 and to a lesser extent by CYP2C9. Increase in the exposure of rimegepant can be attributed to combined inhibition of CYP2C9 and CYP3A4 with fluconazole administration suggesting a minor contribution from CYP2C9. Thus, CYP2C9 inhibition alone is not expected to significantly affect rimegepant exposures. P-gp and BCRP Inhibitors In a dedicated drug interaction study, concomitant administration of NURTEC ODT with cyclosporine (a potent P-gp and BCRP inhibitor) and with quinidine (a potent P-gp inhibitor) resulted in an increase of similar magnitude in rimegepant exposure (AUC and C max by 1.6 and 1.4 fold with cyclosporine, and by 1.6 and 1.7 fold with quinidine, respectively) [see Drug Interactions (7.3) ]. Therefore, concomitant administration of NURTEC ODT with BCRP inhibitors is not expected to have a clinically significant impact on rimegepant exposures. Other Drugs: No significant pharmacokinetic interactions were observed when rimegepant was concomitantly administered with oral contraceptives (norelgestromin, ethinyl estradiol), midazolam (a sensitive CYP3A4 substrate), metformin (a MATE1 substrate), or sumatriptan [see Clinical Pharmacology (12.2) ].

14 CLINICAL STUDIES 14.1 Acute Treatment of Migraine The efficacy of NURTEC ODT for the acute treatment of migraine with and without aura in adults was demonstrated in a randomized, double-blind, placebo-controlled trial: Study 1 (NCT03461757). Patients in the study were randomized to receive 75 mg of NURTEC ODT (N=732) or placebo (N=734). Patients were instructed to treat a migraine of moderate to severe headache pain intensity. Rescue medication (i.e., NSAIDs, acetaminophen, and/or an antiemetic) was allowed 2 hours after the initial treatment. Other forms of rescue medication such as triptans were not allowed within 48 hours of initial treatment. Approximately 14% of patients were taking preventive medications for migraine at baseline. None of the patients in Study 1 were on concomitant preventive medication that act on the CGRP pathway. The primary efficacy analyses were conducted in patients who treated a migraine with moderate to severe pain. NURTEC ODT 75 mg demonstrated an effect on pain freedom and most bothersome symptom (MBS) freedom at two hours after dosing, compared to placebo. Pain freedom was defined as a reduction of moderate or severe headache pain to no headache pain, and MBS freedom was defined as the absence of the self-identified MBS (i.e., photophobia, phonophobia, or nausea). Among patients who selected an MBS, the most commonly selected symptom was photophobia (54%), followed by nausea (28%), and phonophobia (15%). In Study 1, the percentage of patients achieving headache pain freedom and MBS freedom two hours after a single dose was statistically significantly greater in patients who received NURTEC ODT compared to those who received placebo (Table 1).

Figure 2: Percentage of Patients Achieving MBS Freedom within 2 Hours in Study 1 In Study 1, statistically significant effects of NURTEC ODT compared to placebo were demonstrated for the additional efficacy endpoints of pain relief at 2 hours, sustained pain freedom 2-48 hours, use of rescue medication within 24 hours, and the percentage of patients reporting normal function at two hours after dosing (Table 2). Pain relief was defined as a reduction in migraine pain from moderate or severe severity to mild or none. The measurement of the percentage of patients reporting normal function at two hours after dosing was derived from a single item questionnaire, asking patients to select one response on a 4-point scale; normal function, mild impairment, severe impairment, or required bedrest.

Study 2 enrolled adult patients with at least a 1-year history of migraine (with or without aura). Patients experienced an average of 10.9 headache days during the 28-day observational period, which included an average of 10.2 migraine days, prior to randomization into the trial. Patients were randomized to receive every other day dosing of rimegepant 75 mg (N=373) or placebo (N=374) for 12 weeks. Patients were allowed to use acute headache treatments (i.e., triptans, NSAIDs, acetaminophen, antiemetics, muscle relaxants, and aspirin) as needed. Approximately 10% of patients were taking one preventive medication for migraine at baseline. The use of a concomitant medication that acts on the CGRP pathway was not permitted for either the acute or preventive treatment of migraine. The study excluded patients with myocardial infarction, acute coronary syndrome, percutaneous coronary intervention, cardiac surgery, stroke, or transient ischemic attack within six months of screening. The primary efficacy endpoint for Study 2 was the change from baseline in the mean number of monthly migraine days (MMDs) during Weeks 9 through 12 of the double-blind treatment phase. The percentage of patients who achieved at least a 50% reduction from baseline in moderate to severe MMDs during Weeks 9 through 12 of the double-blind treatment phase compared to placebo was also evaluated. Rimegepant 75 mg dosed every other day demonstrated statistically significant improvements for these efficacy endpoints compared to placebo, as summarized in Table 3.

8.5 Geriatric Use In pharmacokinetic studies, no clinically significant pharmacokinetic differences were observed between elderly and younger subjects. Clinical studies of NURTEC ODT did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to NURTEC ODT during pregnancy. For more information, healthcare providers or patients are encouraged to contact: 1-877-366-0324, email nurtecpregnancyregistry@ppd.com, or visit nurtecpregnancyregistry.com. Risk Summary There are no adequate data on the developmental risk associated with the use of NURTEC ODT in pregnant women. In animal studies, oral administration of rimegepant during organogenesis resulted in adverse effects on development in rats (decreased fetal body weight and increased incidence of skeletal variations) at exposures 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 miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. The estimated rate of major birth defects (2.2 to 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 rimegepant (0, 10, 60, or 300 mg/kg/day) to pregnant rats during the period of organogenesis resulted in decreased fetal body weight and an increased incidence of fetal skeletal variations at the highest dose tested (300 mg/kg/day), which was associated with maternal toxicity. Plasma exposures (AUC) at the no-effect dose (60 mg/kg/day) for adverse effects on embryofetal development were approximately 45 times that in humans at the maximum recommended human dose (MRHD) of 75 mg/day. Oral administration of rimegepant (0, 10, 25, or 50 mg/kg/day) to pregnant rabbits during the period of organogenesis resulted in no adverse effects on embryofetal development. The highest dose tested (50 mg/kg/day) was associated with plasma exposures (AUC) approximately 10 times that in humans at the MRHD. Oral administration of rimegepant (0, 10, 25, or 60 mg/kg/day) to rats throughout gestation and lactation resulted in no effects on pre- or postnatal development. The highest dose tested (60 mg/kg/day) was associated with plasma exposures (AUC) approximately 24 times that in humans at the MRHD.

8 USE IN SPECIFIC POPULATIONS Exposures were significantly higher in subjects with severe hepatic impairment. Avoid use in patients with severe hepatic impairment (Child-Pugh C).

The highest dose tested (60 mg/kg/day) was associated with plasma exposures (AUC) approximately 24 times that in humans at the MRHD. 8.2 Lactation Risk Summary A lactation study was conducted, and the results have established a relative infant dose of less than 1% of the maternal weight-adjusted dose and the milk-to-plasma ratio of 0.20 (see Data ) . These data support that transfer of rimegepant into breastmilk is low. There are no data on the effects of rimegepant on a breastfed infant or on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for NURTEC ODT and any potential adverse effects on the breastfed infant from NURTEC ODT or from the underlying maternal condition. Data A study was conducted in twelve healthy adult lactating women who were between 2 weeks and 6 months postpartum and were administered a single oral dose of rimegepant 75 mg. The relative infant dose was < 1%. The average milk to plasma ratio was 0.20. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use In pharmacokinetic studies, no clinically significant pharmacokinetic differences were observed between elderly and younger subjects. Clinical studies of NURTEC ODT did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. 8.6 Hepatic Impairment No dosage adjustment of NURTEC ODT is required in patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment. Plasma concentrations of rimegepant were significantly higher in subjects with severe (Child-Pugh C) hepatic impairment. Avoid use of NURTEC ODT in patients with severe hepatic impairment [see Clinical Pharmacology (12.3) ] . 8.7 Renal Impairment No dosage adjustment of NURTEC ODT is required in patients with mild, moderate, or severe renal impairment. NURTEC ODT has not been studied in patients with end-stage renal disease and in patients on dialysis. Avoid use of NURTEC ODT in patients with end-stage renal disease (CLcr < 15 mL/min) [see Clinical Pharmacology (12.3) ] .
