Primary Outcome Measures:
  • Safety: To assess the safety and tolerability of the combination maraviroc and dapivirine gel, the endpoint was the proportion of women in the four arms experiencing specific, protocol defined safety events during the study (see description). [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
    • Mucosal abnormalities (as defined in the WHO/CONRAD manual) visible during naked eye examination and/or colposcopy;
    • Abnormal vaginal pH and/or abnormal vaginal flora during the course of the trial;
    • Positive diagnostic tests for trichomonas, gonorrhoea and/or chlamydia;
    • At least one adverse event during the 2 month trial period;
    • Any laboratory abnormalities on haematology, electrolytes, liver function, and renal function.

  • Pharmacokinetics: assessment of local and systemic pharmacokinetics of maraviroc and dapivirine in plasma, vaginal fluid and cervical tissue before, during and after 11 days. [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
