About this study

Official title: Comparative Effectiveness of Dulaglutide, Semaglutide, and Tirzepatide in Preventing Cardiovascular Events in Patients With Type 2 Diabetes and Obesity With or Without Atherosclerotic Cardiovascular Disease.

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. Randomized controlled trials (RCTs) have demonstrated cardiovascular benefits of the modern incretin therapies semaglutide and tirzepatide in selected populations. SUSTAIN-6 (NCT01720446) and SURPASS-CVOT (NCT04255433) showed reductions in cardiovascular events with semaglutide and tirzepatide among patients with T2DM at high cardiovascular risk, findings that were also replicated in clinical practice settings (NCT06659744, NCT07088718). The REWIND trial (NCT01394952) demonstrated similar cardiovascular efficacy for dulaglutide and suggested benefit in both patients with and without prior cardiovascular disease.4 These findings raise the broader question of whether cardiovascular benefits of modern incretin therapies extend to individuals without established atherosclerotic cardiovascular disease (ASCVD) when used in routine clinical practice.

To address this question, this comparative effectiveness study using a target trial emulation framework will assess the incretin therapies dulaglutide, semaglutide, and tirzepatide vs sitagliptin (used as an active comparator placebo proxy) on major adverse cardiovascular events (MACE) among individuals with type 2 diabetes (T2DM) and overweight with or without ASCVD.

Although many features of the target trial cannot be directly replicated in healthcare claims, measurements of key design features, including outcomes, exposures, and inclusion/exclusion criteria, were designed 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 analyses will be new-user active-comparative studies, conducted using 3 national United States claims databases, where we compare the effect of dulaglutide, semaglutide, and tirzepatide vs sitagliptin on preventing atherosclerotic cardiovascular events.

Questions about this trial

What is this clinical trial studying?

An observational study of Type 2 Diabetes and Overweight, 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 5 inclusion and 23 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 myocardial infarction, stroke, or all-cause mortality (with ASCVD) (time frame: Through study completion until first of outcome, disenrollment, end of study period, 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 or DPP4i). The study lists 4 primary outcomes in all. 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.
