Effects of Semaglutide in HIV-Associated Lipohypertrophy

This is a randomized, double-blinded, placebo-controlled trial designed to assess the effect of the GLP-1 receptor agonist, semaglutide, on visceral and ectopic fat, insulin resistance, inflammation markers, and the downstream effect of cardiovascular risk in people with HIV. The primary endpoints will be visceral and ectopic fat changes over the study period. The secondary endpoints will include changes in markers of inflammation, immune activation, gut integrity, and cardiovascular disease risk assessment.

Key information

About this study

This study is a phase IIb, randomized, double-blinded, placebo-controlled clinical trial of semaglutide in people with HIV-associated lipohypertrophy. Participants will be recruited from 1 site (Cleveland, OH). The duration of the study will be 56 weeks. The interventional phase will last 32 weeks, followed by a 24-week observational phase to assess the sustainability of the intervention. Participants will be randomized 1:1 to receive semaglutide by subcutaneous injection once weekly for 32 weeks (8-week dose escalation phase followed by full-dose for 24 weeks) or matching placebo. The primary objective of this clinical trial is to determine the efficacy of semaglutide in treating lipohypertrophy among non-diabetic people living with HIV by reducing fat accumulation and ectopic fat deposition, altering adipokine levels, improving endothelial function and arterial stiffness, down-regulating key pro-inflammatory cytokines and immune activation without modifying microbial translocation and gut integrity markers.
