Safety Study for Prospective Assessment of Pregnancy Outcomes in Patients Treated With Tildrakizumab

Overview

This study will utilize a prospective, observational, exposure cohort design to examine pregnancy and infant outcomes in women and infants who are exposed to tildrakizumab during pregnancy to treat an approved indication.

The pregnancy registry cohort study will be conducted by the Organization of Teratology Information Specialists (OTIS), which is a network of university and health department based information centers serving pregnant women and healthcare providers throughout North America. These services provide a basis for collaborative research such as this Registry.

These Services located throughout the United States (US) and Canada will serve as a source of referrals not only for tildrakizumab-exposed pregnancies but also for similarly ascertained disease-matched comparison pregnant women who have not used tildrakizumab in pregnancy.

The target follow-up period will be until end of pregnancy and 1 year of age for live born infants.
