Details and patient eligibility


Phase III trial evaluating doravirine as an alternative to dolutegravir in treatment naïve people living with HIV-1 infection.

Full description

Phase III, multicenter, open-label, randomized, non-inferiority clinical trial which aims to assess the non-inferiority of doravirine in association with tenofovir and lamivudine, as compared to dolutegravir in association with tenofovir and lamivudine or emtricitabine. This trial will be implemented in Brazil, Cambodia, Cameroon, Côte d'Ivoire, France and Mozambique. Six hundred and ten patients will be enrolled and followed for 96 weeks after entry in the trial (=ART initiation). Primary endpoint will assess virological efficacy at Week 48, measured by the proportion of subjects achieving HIV-1 RNA <50 copies/mL, in HIV-1 infected, treatment-naive subjects with pre-treatment viral load (HIV-1 RNA) ≥ 1,000 copies/mL. Secondary endpoints are planned at W48 and W96.

Inclusion criteria

  • Be at least 18 years of age on the day of signing the informed consent.
  • Be HIV-1 positive as determined according to national testing strategies
  • Have a plasma HIV-1 RNA ≥1000 copies/mL within 30 days prior to the randomization,
  • Have HIV treatment indication based on physician assessment according to local treatment guidelines
  • Be naïve to antiretroviral therapy (ART) including investigational antiretroviral agents
  • For women of childbearing potential i.e. women of childbearing age who are not menopausal, or permanently sterilized (e.g. tubal occlusion, hysterectomy, bilateral salpingectomy) or not refraining from sexual activity: negative urinary test for pregnancy and acceptance to use contraceptive methods
  • Understand the study procedures and voluntarily agree to participate by giving written informed consent for the trial.

Exclusion criteria

  • Have the following laboratory values at screening visit, within 30 days prior to the randomization:

    • AST (SGOT) and ALT (SGPT) >4.0 x upper limit of normal
    • Estimated glomerular filtration rate at time of screening <60 mL/min/1.73m², based on the CKD-EPI equation
  • Has participated in a study with an investigational compound/device within 30 days prior to signing informed consent or anticipates participating in such a study involving an investigational compound/device during the course of this study.

  • Has used systemic immunosuppressive therapy or immune modulators within 30 days prior to treatment in this study or is anticipated to need them during the course of the study

  • Requires or is anticipated to require any of the prohibited or contraindicated medications noted in the trial protocol.

  • Has significant hypersensitivity or other contraindication to any of the components of the study drugs.

  • Has a current (active) diagnosis of acute hepatitis, with AST (SGOT) and ALT (SGPT) >4.0 x ULN, due to any cause.
