About this study
Official title: Comparative Effectiveness of Semaglutide and Dulaglutide in Patients at Low, Moderate, and High Cardiovascular Risk With Type 2 Diabetes and Overweight
Investigators are building an empirical evidence base for real world data through large-scale emulation of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
Read the detailed description
This is a non-randomized, non-interventional study that is part of the Randomized Controlled Trials Duplicated Using Prospective Longitudinal Insurance Claims: Applying Techniques of Epidemiology (RCT-DUPLICATE) initiative (www.rctduplicate.org) of the Brigham and Women's Hospital, Harvard Medical School. It is intended to assess the comparative effectiveness of semaglutide vs dulaglutide on cardiovascular outcomes in individuals typically treated in clinical practice who are at low, moderate, and high cardiovascular risk with type 2 diabetes (T2DM) and overweight.
Although many features of the target trial cannot be directly replicated in healthcare claims, key design features, including outcomes, exposures, and inclusion/exclusion criteria, were selected to proxy those features from the target trial. Randomization cannot be achieved in healthcare claims data but was proxied through a statistical balancing of measured covariates according to standard practice.
The database study will be a new-user active-comparative study, conducted using 3 national United States claims databases, where the effect of semaglutide vs dulaglutide on the composite end point of all-cause mortality, myocardial infarction, or stroke will be assessed. Clinical guidelines during the study period recommended both injectable semaglutide and dulaglutide for the same indications of glucose lowering and cardiovascular risk reduction.

Questions about this trial
What is this clinical trial studying?
An observational study of Type 2 Diabetes Mellitus and Obesity, run by Brigham and Women's Hospital at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Composite of all-cause mortality, myocardial infarction, or stroke. (time frame: 1 day after cohort entry until outcome, disenrollment, end of study period, death, 365 days after cohort entry, discontinuation (45 days grace and risk window), switch between study arms, nursing home admission, or start of any other GLP-1-RA). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Jul 2026.
