Official title

Assessment of Contraceptive Safety and Effectiveness in Cystic Fibrosis: A Retrospective Analysis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The long-term goal is to study the safety and effectiveness of hormonal contraception for women with cystic fibrosis (CF) and contribute to national guidelines that the Cystic Fibrosis Foundation and the Centers for Disease Control and Prevention (CDC) provide to clinicians. The study objectives are to determine whether hormonal contraceptive methods improve overall pulmonary health, worsen CF-related disease or CF liver disease, or are effective against unwanted pregnancy with concomitant CF transmembrane conductance regulator (CFTR) modulator use. The hypothesis is that hormonal contraceptive methods are safe and do not worsen CF-related complications over time,improve FEV-1 when compared to non-hormonal users, and oral birth control methods with CFTR modulator use.
