Experimental: to switch from the NNRTI/PI to maraviroc
to switch from the NNRTI/PI to maraviroc
Drug: maraviroc
HAART regimen including 2 NRTI/NtRTIs plus maraviroc
Active Comparator: to continue with the same approach
to continue with the same approach
Drug: control group

HAART regimen including 2 NRTI/NtRTIs plus one of the following :

  • 1 PI/ritonavir (lopinavir/ritonavir, atazanavir/ritonavir, fosamprenavir /ritonavir, tipranavir/ritonavir, darunavir/ritonavir)
  • or ATV/unboosted (in a regimen without tenofovir)
  • or 1 NNRTI (nevirapine or efavirenz).

Detailed Description:

This is a 48 week randomized, prospective, controlled, open-label, proof-of-concept pilot clinical trial.

Patients with HIV-1 infection on HAART regimen including 2 NRTI/NtRTIs plus one of the following : 1 PI/ritonavir (lopinavir/ritonavir, atazanavir/ritonavir, fosamprenavir /ritonavir, tipranavir/ritonavir, darunavir/ritonavir) or ATV/unboosted (in a regimen without tenofovir) or 1 NNRTI (nevirapine or efavirenz).

Patients will be randomized to switch from the NNRTI/PI to maraviroc (300 mg /12 h) or to continue with the same approach.

The primary endpoint would be the percentage of patients who maintain virological suppression at week 48.
