What this trial studies

The WAKIX Pregnancy Registry is a prospective, observational cohort study in the US that aims to assess the effects of pitolisant exposure during pregnancy on maternal, fetal, and infant outcomes. Pregnant women who consent to participate will have their data collected from routine medical records, with no additional tests required. The study includes women with and without narcolepsy who have been exposed to pitolisant or comparator products. The registry follows FDA guidelines for pregnancy exposure studies.

Who should consider this trial

Good fit: Ideal candidates include pregnant women of any age who have been exposed to pitolisant or comparator products.

Not a fit: Patients who have already experienced pregnancy outcomes prior to contacting the registry will not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could provide valuable insights into the safety and effects of pitolisant during pregnancy, guiding treatment decisions for pregnant women with narcolepsy.

How similar studies have performed: While observational studies on medication exposure during pregnancy are common, this specific registry approach for pitolisant is novel and untested.
