NCT01805427

  Purpose

The concentration of the third agent in antiretroviral therapy [Non Nucleoside Reverse Transcriptase Inhibitor (NNRTI), or boosted Protease inhibitor (PI) ] is different according to the body weight or body composition and therapeutic monitoring may be necessary in overweight HIV patients.

The investigators aim at measuring the individual trough concentrations of interest [at steady state for NNRTI and boosted PI] in overweight and normal weight HIV+ patients.

Primary Outcome Measures:
  • comparison of the trough concentrations between patients with Body Mass Index (BMI)<25 kg/m2 and patients with BMI >25 kg/m2 [ Time Frame: the day of enrollment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • comparison of the occurrence of virologic failure within each patient group [ Time Frame: the day of enrollment ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • occurrence of adverse events in each patient group [ Time Frame: the day of enrollment ] [ Designated as safety issue: Yes ]

Enrollment: 140
Study Start Date: September 2012
Study Completion Date: November 2013
Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts
patients treated with efavirenz
HIV-infected on stable HAART regimen with efavirenz
patients treated with atazanavir
HIV-infected patients on stable HAART regimen with atazanavir
patients treated with darunavir
HIV-infected patients on stable HAART regimen with darunavir

Detailed Description:

Our primary endpoint is the individual trough concentrations of interest at steady state for NNRTI or boosted PI; Principal outcome measure: comparison of the concentrations between patients <25kg/m2 and patients<25kg/m2

Secondary endpoints:

  • Occurrence of virologic failure
  • Occurrence of clinical/biological adverse events
  • Percentage of patients with concentration within the therapeutic range
  • Body composition Secondary outcome measures: comparison of the occurrence of virologic failure, occurrence or adverse event, patients with concentration within the therapeutic range between groups. Correlation between body composition and concentration.

Methodology, study design:

open-labelled monocentric study.

Sample size:

It will be a descriptive experimental study involving 120 overweight subjects, 120 normal weight subjects

Inclusion criteria :
