Study design

The Tirzepatide Pregnancy Registry study is a multi-country, prospective, observational cohort study designed to evaluate the association between tirzepatide exposure during pregnancy and subsequent maternal, fetal, and infant outcomes.

Main study objective

The aim of the Tirzepatide Pregnancy Registry study is to compare the maternal, fetal, and infant outcomes of individuals treated with tirzepatide for weight management during pregnancy (tirzepatide exposed cohort) with outcomes in two comparator cohorts:
 Anti-obesity medication [AOM] active comparator cohort: Individuals who are treated with pharmacotherapy other than tirzepatide or other therapies with GLP-1 receptor agonist (GLP-1 RA) activity for weight management during pregnancy
 AOM unexposed comparator cohort: Individuals who have obesity or are overweight with at least one weight
related comorbid condition at the time of conception; and who are not treated with tirzepatide, GLP-1 RA
therapies, or any products for weight management during pregnancy

The primary objective is to describe and compare the overall prevalence of major congenital malformations (MCM) among individuals treated with tirzepatide for weight management during pregnancy relative to the two comparator cohorts of pregnant individuals (AOM active comparator cohort and AOM unexposed comparator cohort).

The secondary objective is to describe and compare the prevalence of maternal pregnancy complications, fetal and infant outcomes other than MCM, and postnatal growth and development outcomes between pregnant individuals treated with tirzepatide for weight management during pregnancy and the two
comparator cohorts of pregnant individuals (AOM active comparator cohort and AOM unexposed comparator cohort). The secondary outcomes of interest are as follows:
Maternal pregnancy complications
 Gestational diabetes
 Pregnancy-induced hypertension
 Pre-eclampsia
 Eclampsia
Fetal outcomes
 Spontaneous abortion (SAB)
 Induced abortion
 Stillbirth
Infant outcomes
 Minor congenital malformations
 Preterm birth
 Small for gestational age (SGA)
Postnatal growth and development outcomes
 Postnatal growth deficiency (up to one year of age)
 Infant developmental delay (up to one year of age)
