A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study evaluates the outcomes for mothers and infants when pregnant women with migraines are treated with Ubrelvy (ubrogepant) or Qulipta (atogepant). It aims to enroll approximately 1,884 participants, including those exposed to either medication and a comparator group of unexposed women. The study will track fetal, maternal, and infant health outcomes for up to 12 months after birth. Participants will be monitored based on their treatment as prescribed by their healthcare providers.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety of migraine treatments during pregnancy, helping to inform clinical decisions.

How similar studies have gone: While there have been studies on migraine treatments, this specific observational approach focusing on pregnancy outcomes is relatively novel.
