Study description

This non-interventional study (NIS) is designated as a post-authorization safety study (PASS) and is a commitment to the US FDA. This is an observational cohort study using two US-based administrative healthcare claims databases, each of which will be used to identify pregnancy episodes among individuals with UC who are exposed to etrasimod during pregnancy or who are unexposed to etrasimod but exposed to other advanced UC treatments during pregnancy.

Research question: Is there an increased risk of adverse pregnancy and/or infant outcomes in individuals who are exposed to etrasimod during pregnancy?

Primary objective: Describe the prevalence of major congenital malformations (MCMs) in infants born alive to pregnant individuals with a diagnosis of ulcerative colitis (UC) who are (1) exposed to etrasimod during pregnancy (Etrasimod Cohort) and (2) unexposed to etrasimod but exposed to other advanced UC treatments during pregnancy (Other Advanced UC Treatments Cohort) and compare the prevalence between cohorts if sample size permits

Secondary objective: Describe the prevalence of pregnancy (spontaneous abortion, pregnancy termination, gestational hypertension, pre-eclampsia, eclampsia, and stillbirth) and infant (preterm birth and small for gestational age) outcomes among individuals in the Etrasimod Cohort and the Other Advanced UC Treatments Cohort and compare the prevalence between cohorts if sample size permits
