Atogepant (Monograph)
Brand name: Qulipta
Drug class: Calcitonin Gene-related Peptide (CGRP) Antagonists
Introduction
Antimigraine agent; a small molecule calcitonin gene-related peptide (CGRP) receptor antagonist.
Uses for Atogepant
Preventive Treatment of Episodic Migraine
Preventive treatment of episodic migraine in adults.
Current consensus statement from the American Headache Society (AHS) discusses the evidence for atogepant in the preventive treatment of episodic migraines. AHS states that treatment plans involving the preventive use of "gepants" should be based on regimens used in clinical trials and individualized according to the needs of each patient. Repeated treatment with these drugs does not appear to be associated with medication overuse headache or liver toxicity.
Preventive Treatment of Chronic Migraine
Preventive treatment of chronic migraine in adults.
Although the current consensus statement from the AHS does not discuss the specific evidence for use of atogepant in the preventive treatment of chronic migraines, AHS states that treatment plans involving the preventive use of the "gepant" class of medications should be based on regimens used in clinical trials and individualized according to the needs of each patient.

Special Populations
Hepatic Impairment
Mild or moderate hepatic impairment (Child-Pugh class A or B): No dosage adjustment necessary.
Severe hepatic impairment (Child-Pugh class C): Avoid use.
Renal Impairment
Mild or moderate renal impairment (Clcr 30–89 mL/minute): No dosage adjustment necessary.

-
Hypersensitivity to atogepant or any of the inactive ingredients in the formulation.
Warnings/Precautions
Sensitivity Reactions
Hypersensitivity Reactions
Hypersensitivity reactions, including anaphylaxis, dyspnea, rash, pruritus, urticaria, and facial edema, reported. Can occur days after administration.
Discontinue atogepant and institute appropriate therapy if a hypersensitivity reaction occurs.
Specific Populations
Pregnancy
No adequate data on developmental risk associated with use of atogepant in pregnant women. Based on animal studies, may cause fetal harm. Adverse effects on embryofetal development (e.g., decreased fetal and offspring body weight, increased fetal structural variations) observed in animals at dosages higher than those used clinically.
Possible increased risk of preeclampsia and gestational hypertension during pregnancy in women with migraine.
Lactation
Not known whether distributed into human milk; distributed into milk in rats. Effects on the breast-fed infant and on milk production not known. Consider known benefits of breast-feeding along with mother's clinical need for atogepant and any potential adverse effects on the breast-fed infant from the drug or underlying maternal condition.
Pediatric Use
Safety and efficacy not established.
Geriatric Use
Insufficient experience in patients ≥65 years of age to determine whether geriatric patients respond differently than younger adults. Clinically important pharmacokinetic differences not observed between geriatric and younger individuals.
Select dosage with caution, usually starting at the low end of the dosage range.
Hepatic Impairment
Exposure is increased in patients with hepatic impairment.
Dosage adjustment not necessary in patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) hepatic impairment.
Avoid use in patients with severe (Child-Pugh class C) hepatic impairment.
Renal Impairment
Pharmacokinetics not substantially altered in patients with mild or moderate renal impairment (Clcr 30–89 mL/minute); dosage adjustment not necessary.
Not studied in patients with severe renal impairment (Clcr 15–29 mL/minute) or end-stage renal disease (Clcr <15 mL/minute). Recommended dosage is 10 mg once daily for prevention of episodic migraine in patients with severe renal impairment or end-stage renal disease. Avoid use in patients with severe renal impairment or end-stage renal disease for prevention of chronic migraine.

Actions
-
Small molecule calcitonin gene-related peptide (CGRP) receptor antagonist (sometimes referred to as a gepant); binds to CGRP receptors with high affinity, blocking the binding of CGRP to the receptor and preventing subsequent receptor activation.
-
CGRP is a potent vasodilator and pain-signaling neuropeptide that has been associated with migraine pathophysiology. CGRP and its receptors are located at sites that are relevant to migraine development such as the trigeminal neurons and are also widely distributed throughout the central and peripheral nervous systems as well as in nonneuronal tissues throughout the body.
-
Increased serum CGRP concentrations observed in individuals during acute migraine attacks; serum CGRP concentrations return to normal after resolution of the migraine. IV infusion of CGRP induces migraines in patients with a history of migraine.
-
Unlike 5-HT1 receptor agonists (triptans), CGRP receptor antagonists do not appear to cause vasoconstriction. Atogepant does not appear to prolong the QT interval in dosages up to 5 times the maximum recommended daily dosage.
Advice to Patients
-
Inform patients about the risk of hypersensitivity reactions and possible signs and symptoms of such reactions. Advise patients to discontinue atogepant and seek immediate medical attention if they experience any symptoms of a hypersensitivity reaction.
-
Inform patients that atogepant may interact with certain other drugs. Advise patients to inform their clinician about concomitant use of any prescription and OTC drugs and dietary or herbal supplements (e.g., St. John's wort) as well as any concomitant illnesses (e.g., hepatic or renal disease).
-
Importance of women informing clinicians if they are or plan to become pregnant or are breast-feeding or plan to breast-feed.
-
Importance of informing patients of other important precautionary information.
