Summary:

      This is a proof of concept study to determine whether an extended release vaginal film can
      deliver drug for seven days. Two film formulations containing MK-2048 which differ by
      dissolution and spreadability attributes will be compared for safety and pharmacokinetic
      outcomes.

          -  Agree to refrain from use of vaginal device or products (for example, lubricants,
             creams, suppositories) throughout participation in the study. Tampons may be used

          -  Willingness to undergo all study-related assessments and follow all study-related
             procedures

          -  At screening and enrollment, agrees not to participate in other research studies
             involving drugs, medical devices, or vaginal products while enrolled in this trial

          -  Participants over the age of 21 (inclusive) must have documentation of a satisfactory
             Pap within three years prior to Enrollment consistent with Grade 0 according to the
             Female Genital Grading Table for Use in Microbicide Studies Addendum 1 (Dated November
             2007) to the Division of Acquired Immune Deficiency Syndrome Table for Grading Adult
             and Pediatric Adverse Events, Corrected Version 2.1, July 2017, or satisfactory
             evaluation with no treatment required of grade 1 or higher Pap results. If no
             documentation of a Pap smear can be provided, a Pap smear will be collected at the
             screening visit.

        Exclusion Criteria:

          -  Menopause (as defined as amenorrhea for one year or more without an alternative
             etiology)

               3. Surgical procedure involving the pelvis in the 60 days prior to enrollment
                  (includes dilation and curettage or evacuation, and cryosurgery; does not include
                  cervical biopsy for evaluation of an abnormal pap smear)

               4. Participation in a drug, spermicide and/or microbicide study in the 30 days prior
                  to enrollment

             the scheduled Enrollment visit may return at a different date to be re-examined and
             possibly enrolled provided they are still within the screening window and meet all
             criteria.)

          -  Any condition that, in the opinion of the Investigator, would preclude provision of
             consent, make participation in the study unsafe, complicate interpretation of study
