GLP-1 Receptor Agonists to Decrease Ethanol and CVD Risk in HIV
(GL1DER HIV RCT)
What this study is about
The goal of this clinical trial is to learn if the drug semaglutide works to reduce alcohol intake among adults living with HIV. The main questions it aims to answer are: 1. Does semaglutide lower the average number of alcoholic beverages participants drink per week? 2. Does semaglutide lower the average number of cigarettes participants smoke per day? 3.

The goal of this clinical trial is to learn if the drug semaglutide works to reduce alcohol intake among adults living with HIV. The main questions it aims to answer are: 1. Does semaglutide lower the average number of alcoholic beverages participants drink per week? 2. Does semaglutide lower the average number of cigarettes participants smoke per day? 3. Does semaglutide decrease the risk for cardiovascular disease among people living with HIV who drink alcohol and/or smoke tobacco? Researchers will compare the effects of semaglutide to a placebo (a look-alike substance that contains no drug) to see if semaglutide works to lower the alcohol intake among participants each week. Participants will: 1. Take semaglutide for 3 months 2. Visit the research clinic 3 times for checkups and tests 3. Provide blood samples, stool samples, and saliva samples for tests.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
