What this trial studies

This phase IV clinical trial investigates the effectiveness and tolerability of intranasal zavegepant 10 mg for treating acute migraine attacks in individuals already using calcitonin gene-related peptide (CGRP) preventive treatments. Participants must be on stable doses of CGRP-targeting medications for at least two months prior to treatment. The study aims to assess how well zavegepant works in this specific population, with options for participants not currently on CGRP treatments to start rimegepant for migraine prevention. The trial will monitor the outcomes over a defined period to evaluate the benefits of zavegepant.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who experience 2-8 migraine attacks per month and are currently on stable doses of CGRP-targeting preventive medications.

Not a fit: Patients with primary headache disorders other than migraine or those with a history of hypersensitivity to zavegepant will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for acute migraine relief in patients already using preventive therapies.

How similar studies have performed: Other studies have shown positive outcomes with CGRP-targeting treatments, suggesting a promising approach for this trial.
