A Study to Evaluate the Safety of Exposure to Wegovy During Pregnancy

Enrolling by invitation

Conditions studied: Pregnancy, Obesity, Overweight

In brief

This is an observational cohort study using administrative insurance claims data. The aim of this non-interventional study (NIS) is to compare maternal, fetal and infant outcomes of women exposed to Wegovy during pregnancy to a reference population not exposed to Wegovy, so that participants and healthcare providers can make informed treatment decisions.

You may qualify if…

Evidence of a pregnancy end event on a medical claim (example, live birth, stillbirth, or spontaneous abortion) during the pregnancy identification period (that is, 04 June 2021 - 17 February 2034).
Date of conception between 04 June 2021 and 06 May 2033 (that is last menstrual period (LMP) 43 weeks prior to the latest pregnancy end date).
Aged 15-50 and female on the date of the LMP.
Continuous enrolment in the database with medical and pharmacy benefits for at least 6 months prior to the date of conception through 42 days after the pregnancy end date.
Among the pregnancies that meet the inclusion criteria, four main cohorts and two sub cohorts of interest will be identified (two Wegovy-exposed cohorts and two comparison cohorts):
Wegovy-exposed- for greater than or equal to 1 day of Wegovy exposure from 35 days prior to estimated date of conception to end of pregnancy. Two mutually exclusive cohorts will be identified based on first Wegovy exposure during pregnancy.
Wegovy injection-exposed- for greater than or equal to 1 day of Wegovy exposure from 35 days prior to estimated end of pregnancy.
Wegovy tablet-exposed- for greater than or equal to 1 day of Wegovy exposure from 35 days prior to estimated end of pregnancy.
Other AOM-exposed- greater than or equal to1 day of phentermine, diethylpropion, benzphetamine, phendimetrazine, orlistat, or bupropion/naltrexone exposure, defined as the following:
Benzphetamine, diethylpropion, orlistat, or phendimetrazine exposure from one day prior to estimated conception date to end of pregnancy.
Phentermine or bupropion/naltrexone exposure from five days prior to estimated conception date to end of pregnancy.
Cohort with Overweight/Obesity and at least one weight related comorbid condition-
Greater than or equal to 1 diagnosis code for obesity or BMI greater than or equal to 30 kilogram per meter square (kg/m\^2) on a medical claim during the six month pre-pregnancy period.
Greater than or equal to 1 diagnosis code for BMI greater than or equal to 27 kg/m\^2 or less than 30 kg/m\^2 on a medical claim and greater than or equal to 1 non-diagnostic medical claim for dyslipidemia, type 2 diabetes mellitus, or hypertension during the six month pre-pregnancy period.
No exposure to Wegovy or other AOM during the defined exposure window in pregnancy.
Among Wegovy-exposed and Other AOM-exposed pregnancies, the subset with first trimester exposures will be identified as those with greater than or equal to 1 days of exposure at less than 14 WGA.

You may not qualify if…

Pregnancies exposed to other glucagon-like peptide-1 receptor agonist (GLP-1 RA) during the exposure identification window (that is, 35 days prior to estimated conception date through pregnancy end date).
Pregnancies with exposure to both Wegovy and other AOM during the exposure identification window (estimated conception date - 35 days through pregnancy end date).
Pregnancies resulting in multiple infants will be excluded from the analysis of infant outcomes.
