Clinical Trial Summary

A substudy of TMC114FD2HTX4004 that will perform glucose tolerance testing, adipose testing and MRI scan at baseline, 12 and 24 weeks post switch of ART medications.


Clinical Trial Description

Synopsis Full study title: Assessing the impact of integrase strand transfer inhibitors (INSTI) to protease inhibitor (PI) switch on insulin sensitivity and fat metabolism (ADIPOSITY): a sub-study of DEFINE Endpoints and objectives: The following endpoints will be determined 12 and 24 weeks after switch from an INSTI-based antiretroviral therapy (ART) regimen to a PI-based regimen: Primary endpoint: Change in insulin sensitivity (SI) at 12 weeks assessed by using a 3-hour frequently sampled oral glucose tolerance testing (fsOGTT). Secondary endpoints: 1) Change in insulin sensitivity (SI) at 24 weeks assessed by using a 3-hour frequently sampled oral glucose tolerance testing (fsOGTT); 2) Change in insulin secretion during the fsOGTT assessed by using C-peptide deconvolution; 3) Change in intrahepatic triglyceride (IHTG) content measured by magnetic resonance imaging (MRI); 4) Change in adipocyte size by the osmium tetroxide fixation technique; and 5) Change in expression of genes associated with adipose tissue development, lipogenesis, inflammation and endocrine function by RNA sequencing. Hypothesis: Insulin sensitivity will improve following switch from INSTIs to PIs ;
