Changes in Insulin Sensitivity in Healthy Volunteers Taking Tenofovir Alafenamide (TAF)-Containing Antiretroviral Medication

Investigation of possible changes in insulin sensitivity in healthy volunteers taking the following HIV treatment combinations: F/TAF (group 1) as compared to E/C/F/TAF (group 2) as compared to R/F/TAF (group 3). The measurement of insulin sensitivity will be performed in 30 HIV-negative healthy non-obese (BMI 18-25) male volunteers before and after 14±2 days of treatment. The volunteers will be randomly assigned to one of the three groups. Changes in insulin sensitivity will be measured by golden standard hyperinsulinemic euglycemic clamp (HEGC) technique, using glucose and insulin infusion as diagnostic agents
