Eligibility Criteria

Inclusion Criteria

• Signed informed consent.
• HIV-1 infected patients with viremia (VL ≥ 500/mL) on or after their first NNRTI or INI-based cART regimen and meeting one of the two criteria below:.

i) On 1st line Non-nucleoside reverse transcriptase inhibitor (NNRTI) or Integrase inhibitor (INI)-based Combination antiretroviral therapy (cART) with HIV-1 RNA ≥ 500 c/ML after being on the same therapy for at least 12 weeks.

ii) Off 1st line NNRTI or INI-based Combination antiretroviral therapy (cART) for at least 2 weeks after having been on antiviral therapy for at least 4 weeks and who are non-compliant and off first line cART without a history of virologic failure with resistance, with a : HIV-1 RNA ≥ 500 c/ML.
