What this trial studies

This observational project aims to track pregnancies in women who have been treated with Stelara or Tremfya, either during pregnancy or within three months prior to their last menstrual period. The study will evaluate the potential effects of these medications on pregnancy outcomes, including the health and development of the child up to one year after birth. It seeks to identify both visible and subtle defects that may arise from medication exposure during pregnancy, ensuring comprehensive monitoring of fetal outcomes.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety of Stelara and Tremfya during pregnancy, guiding treatment decisions for women with autoimmune diseases.

How similar studies have gone: Other studies have successfully monitored medication exposure during pregnancy, but this specific registry approach is relatively novel.
