Tirzepatide for weight loss and chronic inflammation in people with HIV

Effects of Tirzepatide on Weight Loss and Chronic Inflammation in People With HIV

Phase 2 Interventional University of Hawaii · NCT06935838

This study will try once-weekly tirzepatide injections to help adults with well-controlled HIV who are overweight or obese lose weight and reduce chronic inflammation.

What this trial studies

This is a prospective, open-label cohort of 12 adults with well-controlled HIV on stable antiretroviral therapy who are overweight or obese. Participants will start tirzepatide 2.5 mg subcutaneously once weekly with dose escalation by 2.5 mg every 4 weeks to a target of 7.5 mg. Investigators will collect baseline clinical and HIV labs from the medical record and measure weight change at 12 weeks as the primary outcome. Secondary measures include changes in body composition, liver fat and stiffness, inflammatory and cardiometabolic markers, and monocyte measures, with a 4-week safety follow-up off tirzepatide.

Who should consider this trial

Good fit: Adults (≥18 years) with documented HIV-1 for ≥1 year, HIV-1 RNA <200 copies/mL for ≥6 months, on a stable antiretroviral regimen for ≥1 year, and with BMI ≥27 kg/m2 plus a weight-related condition or BMI ≥30 kg/m2.

Not a fit: Patients with uncontrolled HIV, those not on a stable ART regimen, or people with BMI below the study thresholds are not eligible and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, tirzepatide could produce meaningful weight loss and lower chronic inflammation, potentially improving metabolic health and liver-related measures in people with HIV.

How similar studies have performed: Tirzepatide and related GLP-1/GIP agents have produced substantial weight loss in general populations, but their effects specifically in people with HIV are only beginning to be studied.
