Multiple clinical trials are also underway to determine what other diseases GLP-1 drugs may potentially protect against. The drugs are currently approved for Type 2 diabetes, weight loss and heart disease.

Studies have shown that alongside weight loss and Type 2 diabetes management, the drugs may protect against high blood pressure, liver disease, kidney disease and other health complications of obesity.

Research has also shown that the drugs may reduce the risk of cognitive decline, like dementia.

There have also previously been anecdotal reports that the drugs may assist in reducing addictive behavior including substance abuse, alcohol use or gambling, which researchers continue to investigate.

The FDA will be tasked to review safety and efficacy data from these pending trials to determine whether they meet the standards for approval.
