Tirzepatide's Effects on Epigenetic Aging and Metabolic Restoration in Virally Suppressed People With HIV
A Phase 4 study testing Tirzepatide in people with Human Immunodeficiency Virus (HIV) and Metabolic Dysfunction Associated Steatotic Liver Disease, run by National Taiwan University Clinical Trial Center at 1 site in Taiwan.
Trial 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. Read more about this study

About this study
Official title: Reversing the Biological Clock: Tirzepatide's Effects on Epigenetic Aging and Metabolic Restoration in Virally Suppressed People With HIV
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.
- Conditions
- Human Immunodeficiency Virus (HIV), Metabolic Dysfunction Associated Steatotic Liver Disease, Dyslipidaemia, Diabetes Mellitus, Obesity & Overweight, Metabolic Syndrome
- Being tested
- Tirzepatide
- Keywords
- tirzepatdie, human immunodeficiency virus, metabolic dysfunction associated steatotic liver disease
- Medical subject headings
- Acquired Immunodeficiency Syndrome, Dyslipidemias, Diabetes Mellitus, Obesity, Overweight, Metabolic Syndrome
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TirzepatideDrug
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: 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. |
