Semaglutide for Cocaine Use Disorder
(STAC Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether semaglutide, a medication typically used for diabetes and weight management, is safe and well-tolerated for individuals with cocaine use disorder, regardless of HIV status. Participants will receive either semaglutide or a placebo (a harmless substance resembling the drug) through weekly injections. The trial seeks individuals who have used cocaine frequently in the past two weeks and meet other specific criteria. Participants will visit the clinic weekly for injections and every two weeks for check-ups and assessments. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to important medical advancements.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on glucose-lowering or weight-lowering medications.
Is there any evidence suggesting that semaglutide is likely to be safe for humans?
Research has shown that semaglutide is generally safe for use. The FDA has already approved it for treating type 2 diabetes and aiding weight loss, indicating a well-understood safety profile. In studies on cocaine addiction, semaglutide has shown potential in reducing cravings and use. For example, a 54-year-old patient reported a significant decrease in cocaine cravings over 12 weeks while taking semaglutide.
Although specific information on side effects for cocaine addiction is limited, its existing approval for other uses and early research suggest that semaglutide could be safe for this new purpose. However, like any medication, it may have side effects, so monitoring them carefully during the trial is important.12345Why do researchers think this study treatment might be promising for cocaine use disorder?
Most treatments for cocaine use disorder focus on behavioral therapies and medications like disulfiram or naltrexone, which target the brain's reward system. But semaglutide works differently, originally developed as a treatment for diabetes and obesity, it targets the GLP-1 receptors. This unique mechanism could help reduce cocaine cravings by influencing pathways related to addiction. Researchers are excited about semaglutide because it could offer a new approach by acting on the brain's chemistry in a way that current treatments don't, potentially leading to more effective management of cocaine use disorder. Plus, its once-weekly injection is a convenient option compared to daily medications, making it easier for patients to stick to their treatment plans.
What evidence suggests that semaglutide might be an effective treatment for cocaine use disorder?
Research has shown that semaglutide, which participants in this trial may receive, may help reduce cocaine use. In animal studies, semaglutide lowered cocaine intake and reduced the chances of relapse. A human case study found a significant drop in cocaine cravings, with one person's craving score decreasing from 5.6 to 2.3 over 12 weeks. Researchers believe semaglutide can make cocaine less rewarding, reducing its temptation. These findings suggest semaglutide could be useful in treating cocaine use disorder.12346
