Italian Real-life obServational Study on the effecTiveness, sAfety and Tolerability of Atogepant in Migraine Patients

Atogepant is a small molecule calcitonin gene- related peptide (CGRP) receptor antagonist, part of the gepants family. It is a second generation gepant, currently approved for the preventive treatment of episodic and chronic migraine. Previously randomized, placebo-controlled phase 2/3 trials demonstrated its effectiveness and tolerability in the preventive setting for patients with episodic and chronic migraine, associated with a good tolerability profile. The most commonly reported adverse events were upper respiratory tract infections, urinary infections, nausea and constipation. In this prospective multicentric study the investigators aim to evaluate atogepant effectiveness and tolerability as preventive migraine treatment in a real-world setting. Subjects who meet the inclusion criteria will be enrolled and will participate in the study. Baseline demographic and clinical data will be collected at the baseline. patients will take atogepant 60 mg daily for at least 12 weeks up to two years, according to effectiveness, tolerability and eventual approval of reimbursability criteria. Data will be collected at baseline and every three months for two years. Subjects will be asked to keep a headache diary to collect monthly headache and migraine days, migraine severity, associated symptoms and drug consumption. Questionnaires will be collected every three months. Data collection will focus on: i) demographic data, ii) migraine history, iii) pain intensity, iv) presence and evolution of migraine associated symptoms and aura, v) migraine associated disability, vi) tolerability and eventual treatment- emergent adverse events, vii) treatment persistence. The online database REDCap will be used for data collection.
