Official title
Early Metabolic Effects of Antiretroviral Drugs in Healthy Volunteers: A Phase 2 Randomized Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: People with HIV take drugs to keep the amount of virus in their body low. One type of these drugs, called integrase strand transfer inhibitors (INSTIs), can cause weight gain over time. Weight gain can cause diabetes, heart disease, and other serious issues. Researchers want to understand how INSTIs cause weight changes. Objective: To characterize the change in plasma metabolite profile that 4 weeks of each treatment may induce in the absence of HIV infection Eligibility: Healthy people aged 18 to 55. Design: Participants will be screened in the outpatient clinic. They will have a physical exam and blood tests. They will have a nutritional assessment and tests of their heart function. Participants will be randomized to one of four oral treatments: Tenofovir Disoproxil Fumarate TDF, Tenovovir Alafenamide TAF/Vemlidy, Dolutegravir DTG/Tivicay, or both TAF and DTG taken together for 4 weeks. Participants will have a Day 0 visit for the Lead-In Baseline visit for an exam and blood tests and continuous glucose monitor placement. Participants will return in 2wks or Day 14/Wk 2 for a DEXA (dual-energy X-ray absorptiometry). DEXA is a kind of X-ray that measures body fat and bone density. Optional adiopse (fat) tissue biopsy in the abdomen, and optional microbiome specimen collections. Continuous glucose monitor changed. Oral once a day dose medication will be started with education. Participants will return in 2wks or Day 28/Wk 4 for exam, labs, and continuous glucose monitor changed. Participants will return in 2wks or Day 42/Wk 6 for final exam, labs, repeat DEXA scan, repeat adipose tissue biopsy, and microbiome specimen collections.
