NCT07707778

Brief Summary

This study is a pilot, open-lable, two-arm study. The investigators will enroll virally suppressed people living with HIV and obesity to evaluate the effect of tirzepatide on epigenetic aging, assessed by DNA methylation-based clocks using peripheral blood. In parallel, imaging studies will be performed to assess changes in body composition and intrahepatic fat content.

Outcome Measures

Primary Outcomes (2)

  • Second generation epigenetic aging clock

    PCGrimAge will be used to study the measured epigetic age and differences with chronological age in years.

    Baseline, week 33, week 57

  • Third generation epigenetic aging clock

    DunedinPACE will be used to assess the pace of aging, quantifying years of physiological decline per chronological year.

    Baseline, week 33, week 57

Secondary Outcomes (20)

  • Intrahepatic triglycerides

    Baseline, week 33, week 57

  • Change in body composition assessed by dual-energy X-ray absorptiometry (DXA)

    Baseline, week 33, week 57

  • Change from baseline in body fat mass measured by bioelectrical impedance analysis (BIA)

    Baseline, week 33, week 57

  • Patient reported outcome

    Baseline, week 33, week 57

  • Drinking habits

    Baseline, week 33, week 57

  • +15 more secondary outcomes

Other Outcomes (3)

  • Bictegravir pharmacokinetics (PK)

    Baseline, between week 16-32

  • Tenofovir pharmacokinetics (PK)

    Baseline, between week 16-32.

  • Emtricitabine pharmacokinetics (PK)

    Baseline, between week 16-32

Study Arms (2)

Interventional

EXPERIMENTAL

Participants enrolled in the interventional arm will undergo baseline imaging and blood testing, followed by an 8-week diet and nutrition consultation delivered via a smartphone-based application. Participants will then receive tirzepatide treatment for 25 weeks, after which imaging and blood testing will be repeated. Tirzepatide will subsequently be withheld for 24 weeks, with imaging and blood testing repeated once more to assess the persistence of treatment effect. Bictegravir PK/PD study will be done to assess whether tirzepatide will affect bictegravir pharmacokinetics during the study.

Drug: Tirzepatide

Standard of care

NO INTERVENTION

Participants enrolled in the standard of care arm will undergo identical imaging and blood testing, but without bictegravir PK/PD. They will receive diet and nutrition consult delivered via a smartphone-based application throughout the study course.

Interventions

Tirzepatide will be given to the study arm after 8 weeks of diet and nutrition services. Study arm will receive a total of 25 weeks of tirzepatide.
