Secondary Outcome Measures:
  • Incidence of clinical adverse events and / or laboratory alterations. [ Time Frame: twenty-four weeks ] [ Designated as safety issue: No ]
  • Proportion of patients who discontinued treatment due to toxicity or intolerance in each of the treatment arms at 24 weeks follow-up [ Time Frame: twenty four weeks ] [ Designated as safety issue: No ]
  • degree of adhesion during the treatment period [ Time Frame: twenty eight days ] [ Designated as safety issue: No ]
    Measured by pill count and patient adherence questionnaire

  • time to loss of adherence to TARV [ Time Frame: twenty eight days ] [ Designated as safety issue: No ]
