    − Adverse events Grade 2 or higher as defined by the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 1.0, Dec 2004 (Clarification dated August 2009)

  • Pharmacokinetics: Assessments of systemic and local concentrations of dapivirine and maraviroc in plasma, vaginal fluids and cervical tissue, respectively [ Time Frame: 7.5 weeks ] [ Designated as safety issue: No ]
    Assessed during and after 28 days' of continuous use of a vaginal ring containing 25 mg dapivirine, or 100 mg maraviroc, or 25 mg dapivirine + 100 mg maraviroc.

    -- Note: Cervical friability bleeding associated with speculum insertion and/or specimen collection judged to be within the range of normal according to the clinical judgment of the IoR/designee is considered expected non-menstrual bleeding and is not exclusionary.
