About
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.
Full description
This is a phase I randomized trial assessing the safety, acceptability, and pharmacokinetics of two formulations of MK-2048 vaginal film. While the primary objective is to evaluate the safety of the product, the overarching objective of this study is to provide proof of concept that an antiretroviral drug can be delivered in an extended release film formulation to provide drug delivery for 7 days or more after a single application. Forty eight women will be randomized with equal frequency to receive a single dose of a vaginal film containing MK-2048 (either the high Eudragit® or low Eudragit® formulation). The film will be inserted by a clinician on the day of enrollment. Vaginal swabs and plasma will be collected at days 0, 3, 5, 7, 10, 14 and 28 for all participants. On the day of enrollment, some participants may elect to participate in immediate post insertion sample collection (vaginal swab and plasma) at one or two time points within 6 hours of insertion. Genital biopsy samples and a rectal swab will be obtained on day 7, and cervicovaginal lavage will be collected at screening and days 14 and 28. The primary endpoint is the frequency of Grade 2 or higher adverse events. The secondary endpoints are: MK-2048 concentrations in plasma, cervical tissue homogenate, cervicovaginal lavage fluid, rectal and vaginal swab eluents; self-reported assessment of qualities of the experience with the films drawn from existing survey on microbicidal films, and general acceptability ratings drawn from market research methodology.

Menopause (as defined as amenorrhea for one year or more without an alternative etiology)
Hysterectomy
Participant report of any of the following:
Urogenital infection or suspected infection within 7 days of enrollment including: symptomatic candidiasis, trichomonas vaginalis, and symptomatic bacterial vaginosis; or cervical infection, including N. gonorrhoeae, C. trachomatis, or mucopurulent cervicitis; syphilis; herpes simplex virus lesions, or other sores (Note: seropositive herpes simplex virus without active lesions will not be excluded); acute pelvic inflammatory disease; urinary tract infection; recent exposure to a partner with N. gonorrhoeae, C. trachomatis, Trichomonas, syphilis, or non-gonorrheal urethritis
Antibiotic or antifungal therapy (vaginal or systemic) within 7 days of enrollment
As determined by the primary investigator, has any significant uncontrolled active or chronic cardiovascular, renal, liver, hematologic, neurologic, gastrointestinal, psychiatric, endocrine *including poorly controlled diabetes), respiratory, immunologic disorder or infectious disease
Menses-like bleeding at the time of the Enrollment visit* or expected menses-like bleeding within 14 days of the Enrollment visit (*Women who have vaginal bleeding at 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 outcome data, or otherwise interfere with achieving the study objectives
