The study will identify pregnant women exposed to relugolix combination therapy during pregnancy from a United States (US) administrative claims database. The primary outcome measure is major congenital malformations (MCMs) among linked live births. Secondary outcome measures include spontaneous abortion (SAB), stillbirth, small size for gestational age (SGA), and preterm birth. Infants of pregnancies with linked live birth outcomes will be followed up to 12 months of age for identification of MCMs. Anticipated enrollment is 530 live births.
