Overview

Glucagon-like peptide-1 and glucose-dependent insulinotropic polypeptide receptor agonists (GLP-1/GIP agonists) are novel drugs for the treatment of diabetes and obesity. A growing body of evidence suggests that these drugs may also have favorable effects on cardiovascular disease (CVD) outcomes. While the GLP-1/GIP agonists offer promise for both the primary and secondary prevention of CVD, the potential for achieving clinically meaningful weight loss appears to vary by demographic, clinical, and healthcare factors. Understanding whether there is similar variation in cardiovascular risk response to the drugs will be crucial for pinpointing population heterogeneity in their impact. 

We invite proposals for a research project focused on identifying predictors of cardiovascular risk reduction among individuals with obesity who are using GLP-1 receptor agonist medications, such as semaglutide and tirzepatide. Proposals are encouraged to leverage data sources including de-identified claims data, electronic health records and prospective cohort studies. 
 
At the American Heart Association, equity and science are at the center of everything we do.  We encourage applications that are focused on underrepresented populations. 

A successful application will address one or more of the following:

  1. Examine GLP-1/GIP agonist uptake and use patterns in individuals living with CVD and how patterns of use vary across population subgroups disproportionately affected by obesity. 
  2. Develop causal inference approaches to identify the association of GLP-1/GIP agonists with cardiovascular risk reduction in diverse populations. 
  3. Identify heterogeneity in the effects of GLP-1/GIP agonists on cardiovascular outcomes according to demographic, clinical, and healthcare factors using causal inference and/or machine learning methods. 
  4. Develop modeling approaches to project the future burden of CVD and related disparities considering various scenarios of scale-up of GLP-1/GIP agonists in diverse populations. 

The purpose of this Request for Proposal (RFP) announcement is to fund research focused on the potential contribution of GLP-1/GIP agonists to reducing the CVD burden and disparities in the coming years.

The AHA will fund up to three awards. Each award will be $150,000 (including 10% indirect costs) for one year.

  • An additional Amazon Web Services (AWS) service credit (up to $30,000) for use of the American Heart Association Precision Medicine Platform may be provided for computational time, use of AWS tools and infrastructure, and storage. Credit amount will be determined based on estimated need over duration of the grant.

Who we’re looking for:
Proposals are welcomed from researchers with experience in causal inference methods, machine learning, and cardiovascular research. Collaborative proposals involving multidisciplinary teams are encouraged.

Duration
Up to 1 year of funding from date of funding, contingent upon milestones and timelines being met.

Number of Awards
The American Heart Association anticipates awarding up to 3 grants, $150,000 per award.
The American Heart Association reserves the right to determine the final number of awardees.

Precision Medicine Platform, research environment, trial workspace


Each team may be eligible to receive Amazon Web Services computational credits to cover the cost of cloud computing for a secure and private workspace on the American Heart Association’s Precision Medicine Platform to enable investigators in each team to collaborate and analyze data securely.

Data analysis is enabled in secure workspaces by a web interface that allows researchers to code in various languages, including R and Python, and to use statistical software including but not limited to SAS and R studio. The most up-to-date machine learning and artificial intelligence software available from Amazon Web Services is also included. Researchers are also able to install their own tools.

The American Heart Association asks that the grantees also accelerate collaboration through the sharing of data and code as well as the coordination for interoperability of data to facilitate findability and sustainability. The American Heart Association fully supports the FAIR (Findable, Accessible, Interoperable and Reusable) guiding principles of data stewardship.
