        3.1.1 Inclusion Criteria for the Tissue Subset (US sites only) A subset of approximately 24
        participants at US sites will participate in more intensive sampling of vaginal tissue
        during Week 36 (preferred) or Week 44.

        For these participants, the following additional criteria need to be met:

        •Satisfactory Pap results in the 12 calendar months prior to biopsy consistent with Grade 0
        according to the Female Genital Grading Table for Use in Microbicide Studies Addendum 1 to
        the DAIDS Table for Grading Adult and Pediatric Adverse Events, Version 1.0, December 2004
        (Clarification dated August 2009), or satisfactory evaluation with no treatment required of
        Grade 1 or higher Pap result per American Society for Colposcopy and Cervical Pathology
        (ASCCP) guidelines in the 12 calendar months prior to biopsy is required, as indicated.

        If there is no documentation of satisfactory Pap results, and if indicated, the participant
        should be offered to have the test performed by the site prior to enrollment in the Tissue
        Subset. If Pap testing is indicated and participants decline, they are not eligible for the
        Tissue Subset.

          -  In addition to documentation of satisfactory Pap results, women must have normal
             laboratory results for coagulation tests to be eligible for the Tissue Subset.
             Abnormal coagulation test results may indicate an increased risk of bleeding.

          -  Women have to be willing to abstain from vaginal intercourse and practices involving
             insertion of anything in the vagina (drug, douche, penis, or sex toy) for 3 days prior
             to vaginal biopsy and for 7 days post-biopsy, to minimize risk of HIV-1 infection and
             bleeding complications after the procedure.

          -  Participants must not be pregnant at the time of vaginal sampling, based on pregnancy
             test results from previous visits and on the result of urine pregnancy test performed
             on the same day before the proposed vaginal sampling.

          -  Women undergoing biopsy must have received all prior injections of study product, in
             accordance with the protocol, to be eligible for inclusion.

        Exclusion Criteria: Women who meet any of the following criteria will be excluded from the

             confirmed to be HIV-uninfected

          -  Has any other condition that, in the opinion of the site loR or designee, would
             preclude informed consent, make study participation unsafe, interfere with adherence,
             complicate interpretation of study outcome data, or otherwise interfere with achieving
             study objectives (e.g., at increased risk of cardiovascular vents)

        Women who do not meet eligibility criteria because of an abnormal EKG, risk factors for
        TdP, an STI (GC, CT, or syphilis) present at Screening or report of an STI (GC, CT, or

        Women who present at Screening with symptoms consistent with an acute HIV infection or who
        have a reactive HIV test may not be re-screened. Women who do not meet eligibility criteria
        for the study for other reason(s) may be re-screened at a future date at the discretion of
        the site loR.
