Quality of Life and Changes in Metabolism of Lipids and Glucose After Switching to a Nevirapine-based Regimen in HIV+ Patients

HIV Infections Clinical Trial

Official title: An Open, Randomised, Multicentre, Comparative Trial, to Evaluate the Benefit of Switching From a PI-based Regimen to a Nevirapine-based Regimen on the Quality of Life, Patient Adherence, Patient's Perception of Fat Redistribution and Metabolic Changes, in HIV+ Patients Suffering From Fat Abnormalities

Status Completed

Clinical Trial Summary

The purpose of this trial is to compare the effect of switching to nevirapine (Viramune®)-containing regimen on quality of life of patients with fat abnormalities and virological control whilst receiving a PI-based regimen.

Clinical Trial Description

Patients will receive one of the current standard of care regimens for the treatment of HIV infection, i.e. nevirapine (Viramune®) must be administered in conjunction with 2NRTIs, as prescribed by the investigator at the study sites. Patients randomized to the nevirapine (Viramune®)-arm of the study will receive 1x200mg tablet once daily for the first 14 days ("lead in" period) and 1x200 mg tablet twice daily at appropriately spaced intervals subsequently, plus their SOC combination of 2NRTIs as prescribed by the investigators (without changing their prior NRTIs). Patients randomized to continue their standard treatment will receive it as prescribed by the investigators. No dose modification of the study drugs is permitted during the trial. The study drug will be dispensed at randomization and every four weeks thereafter until completion of 48 weeks. After 6 months at least of treatment the switch from PI regimen to NVP regimen will be allowed to all patients included in the PI arm according to patient's willingness. In these patients AST and ALT should be checked at time 0 (switch) and every 2 weeks for 2 months.

Study Hypothesis:

Between treatment comparison of Nevirapine-based regimen versus PI-based regimen will be based on a null hypothesis of no treatment difference. The null hypothesis will be no difference between the two arms at week 24 (month 6th), against the alternative hypothesis that the mean change in physical domain of the QoL will be 10 points score (SD=20) and the difference between triglycerides normalized patients will be 20%.

Comparison(s):

The primary analysis on physical domain of QoL will be performed on the changes between last observation carried forward following the LCOF approach (i.e. visit 6 or in case of premature discontinuation visit 5 or 4) and baseline (visit 2) value using fixed-effects ANCOVA model with center and treatment groups as factors and baseline value and MMA type interaction will be also included in the main model. ;
