Adverse Reactions

Clinical Trials Experience

Clinical Trials Experiance

• Because clinical trials are conducted under widely varying conditions and durations of follow up, 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. 1958 patients with migraines received Atogepant to look into the safety of Atogepant usage on patients. All patients in the study received at least one dosage of Atogepant. In the study, 839 patients were exposed to Atogepant for 6 months while 487 patients were exposed to Atogepant for 12 months.

Study 1 and 2

• 12-week, placebo-controlled clinical studies were conducted on patients to look into the adverse reactions observed in patients receiving 10 mg, 30 mg, or 60 mg of Atogepant once daily. 314 patients received 10 mg of Atogepant, 411 patients received 30 mg of Atogepant, 417 patients received 60 mg of Atogepant, and 408 patients received a placebo that had no Atogepant. The patient population was largely Caucasian (80%), and included 88% women. Constipation, nausea, and fatigue were the most common adverse reactions reported in patients (reported at least 4% and greater than placebo). Discontinuation occurred in patients that displayed nausea (0.5%), fatigue (0.5%), and constipation (0.5%).

Table 2 shows the Adverse Reactions found in patients taking Atogepant from Study 1 and Study 2.

Liver Enzyme Elevations

• 1.0% of patients taking Atogepant had a rate of transaminase elevations over 3 times the upper limit of normal. Some of these patients had asymptomatic cases which were ultimately resolved after discontinuation of Atogepant for 8 weeks.
• 1.8% of patients taking the placebo had a rate of transaminase elevations over 3 times the upper limit of normal.
• Jaundice and severe liver injury were not found in patients.

Decreases in Body Weight

• 3.8% of patients taking 10 mg of Atogepant from Study 1 and Study 2 reported a decrease in weight of at least 7%.
• 3.2% of patients taking 30 mg of Atogepant from Study 1 and Study 2 reported a decrease in weight of at least 7%.
• 4.9% of patients taking 60 mg of Atogepant from Study 1 and Study 2 reported a decrease in weight of at least 7%.
• 2.8% of patients taking the placebo from Study 1 and Study 2 reported a decrease in weight of at least 7%.

Postmarketing Experience

Drug Interactions

CYP3A4 Inhibitors

• Exposure of Atogepant significantly increases with co-administration of Atogepant and itraconazole (a strong CYP3A4 inhibitor).
• 10 mg is recommended dosage of Atogepant when there is concomitant use of Atogepant with a strong CYP3A4 inhibitor.
• Concomitant use of Atogepant with either a moderate or weak CYP3A4 inhibitor requires no change in dosage of Atogepant.

CYP3A4 Inducers

• Exposure of Atogepant significantly decreases with co-administration of Atogepant and a steady state rifampin (a strong CYP3A4 inducer).
• Exposure of Atogepant significantly decreases with concomitant use of Atogepant and moderate inducers of CYP3A4.
• 30 mg or 60 mg is recommended dosage of Atogepant when there is concomitant use of Atogepant with a strong or moderate CYP3A4 inducer.
• Concomitant use of Atogepant with weak CYP3A4 inducer requires no change in dosage of Atogepant.

OATP Inhibitors

• Exposure of Atogepant significantly increases with co-administration of Atogepant and a single dose of rifampin (a OATP inhibitor).
• 10 mg or 30 mg is recommended dosage of Atogepant when there is concomitant use of Atogepant with a OATP inhibitor.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): Reproduction studies done on pregnant rabbits showed a rise in adverse developmental effects such as increased incidence of fetal structural variations with increased exposure of Atogepant (0, 30, 90, or 130 mg/kg/day) during the periods of organogenesis, lactation or pregnancy. At 130 mg/kg/day, pregnant rabbits showed an increase in both skeletal variations and fetal visceral. Maternal toxicity was minimal in pregnant rabbits at 130 mg/kg/day. Adverse effects on plasma exposure and embryofetal development was 3 times for humans at the MRHD in pregnant rabbits at 90 mg/kg/day (no-effect dose). Reproduction studies done on pregnant rats showed a decrease in both skeletal ossification and fetal body weight when given either 125 and 750 mg/kg of Atogepant during the period of organogenesis. Adverse effects on plasma exposure and embryofetal development was 4 times for humans at the MRHD in pregnant rats at 15 mg/kg/day (no-effect dose). At 125 mg/kg/day, a decrease in pup body weight was found in rats during periods of gestation and lactation. At 45 mg/kg/day, the no-effect dose, adverse effects of rats on plasma exposure and pre- and postnatal development was 5 times for humans at the MRHD. Advise pregnant, female patients about the potential harms and risks in the embryo when taking Atogepant.
Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Atogepant in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Atogepant during labor and delivery.

Nursing Mothers

No human data on the effects of Atogepant on the breastfed infant and milk production has been conducted. Studies done on lactating rats show Atogepant levels in milk is 2-fold higher than found in milk of the maternal plasma. Advise female patients about both the possible developmental and health benefits as well as potential adverse effects during nursing when taking Atogepant.

Pediatric Use

There is no FDA guidance on the use of Atogepant with respect to pediatric populations.

Geriatic Use

When looking at younger and elderly patients using Atogepant, no clinically significant pharmacokinetic differences were found between both groups of patients. There was not enough patients 65 years or older in age to determine if there are any response differences to Atogepant in comparison to younger patients. Decrease in frequency of decreased renal, cardiac, or hepatic function was found in elderly patients at the low end of the dosing range for Atogepant.

Gender

There is no FDA guidance on the use of Atogepant with respect to specific gender populations.

Race

There is no FDA guidance on the use of Atogepant with respect to specific racial populations.

Renal Impairment

When looking at the clearance of Atogepant, renal route of elimination plays a minor role. 10 mg of Atogepant once daily is the recommended dosage for patients with end-stage renal disease (CLcr <15 mL/min) or patients severe renal impairment (CLcr 15-29 mL/min). Patients with end-stage renal disease who are undergoing intermittent dialysis should start taking Atogepant after dialysis is completed. Patients with mild or moderate renal impairment require no change to dosage usage.

Hepatic Impairment

Patients with mild or moderate hepatic impairment require no change to dosage usage. Patients with severe hepatic impairment should not take Atogepant.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Atogepant in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance on the use of Atogepant with respect to immunocompromised populations.

Administration

• Take recommended dosage as prescribed by the doctor with or without food.
• Take Atogepant orally and once daily.

Monitoring
