Brief Summary:
Research is currently underway to develop new HIV prevention strategies. Intravaginal rings (IVRs) are one drug delivery method that is currently being studied. This study will evaluate the safety and pharmacokinetics of IVRs containing vicriviroc, MK-2048, and a combination of vicriviroc/MK-2048, in healthy, HIV-uninfected women.

Condition or disease Intervention/treatment Phase
HIV Infections Device: Vicriviroc (MK-4176) Intravaginal Ring (IVR) Device: MK-2048 IVR Device: MK-2048A IVR Device: Placebo IVR Phase 1

Detailed Description:

The development of safe and effective HIV prevention strategies is an important global health priority. IVRs have previously been approved as a delivery method for various medications, and this study will evaluate IVRs containing HIV antiretroviral medications. The purpose of this study is to assess the safety and pharmacokinetics of a combination IVR called MK-2048A that contains vicriviroc (MK-4176) and MK-2048, compared to IVRs containing vicriviroc alone and MK-2048 alone.

This study will enroll healthy, HIV-uninfected women, 18 to 45 years old. Participants will be randomly assigned to receive an IVR containing either vicriviroc, MK-2048, MK-2048A (which contains vicriviroc and MK-2048), or placebo. Participants will receive their assigned IVR at the enrollment visit, and the IVR will be removed on Day 28. Participants will attend study visits at screening, enrollment (Day 0), and Days 1, 2, 3, 7, 14, 21, 28, 29, 30, 31, and 35. Study visits may include behavioral assessments, adherence counseling and assessments, medical history reviews, physical examinations, urine collection, blood collection, pelvic specimen collection, and rectal specimen collection (optional).

  • Age 18 through 45 years (inclusive) at Screening, verified per site SOPs
  • Able and willing to provide written informed consent to be screened for and take part in this study (MTN-027)
  • Able and willing to provide adequate locator information, as defined by the site SOPs

  • Per participant report, using an effective method of contraception at Enrollment, and intending to continue the use of an effective method for the duration of study participation. Effective methods for MTN-027 include: hormonal methods (except contraceptive IVRs), intrauterine device (IUD) inserted at least 28 days prior to enrollment, engages in sex exclusively with women, sterilized (self or partner), and/or sexually abstinent for the past 90 days.
  • Women over the age of 21 (inclusive) must have documentation of a satisfactory Pap within the past 3 years prior to Enrollment 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

Note: This criterion is not applicable to participants who report using a progestin-only method of contraception at Screening, e.g., Depo-Provera or levonorgestrel-releasing IUD nor to participants using continuous combination oral contraceptive pills, as the absence of regular menstrual cycles is an expected, normal consequence in this context.
  • At Screening, participant states a willingness to refrain from inserting any non-study vaginal products or objects into the vagina, including, but not limited to, spermicides, female condoms, diaphragms, contraceptive IVRs, vaginal medications, menstrual cups, cervical caps (or any other vaginal barrier method), douches, lubricants, sex toys (vibrators, dildos, etc.) for the 5 days prior to Enrollment and for the duration of their study participation

Exclusion Criteria:

  • Has any of the following laboratory abnormalities at Screening:

    • Aspartate aminotransferase (AST) or alanine transaminase (ALT) Grade 1 or higher
    • Calculated creatinine clearance less than 60 mL/min by the Cockcroft-Gault formula, where creatinine clearance (female) in mL/min = (140 - age in years) x (weight in kg) x (0.85)/72 x (creatinine in mg/dL)
    • Hemoglobin Grade 1 or higher
    • Platelet count Grade 1 or higher
    • White blood count Grade 2 or higher

    • Note: Otherwise eligible participants with an exclusionary test result (other than HIV, hepatitis B virus [HBV], or HCV) can be re-tested during the screening process. If a participant is re-tested and a non-exclusionary result is documented within 45 days of providing informed consent for screening, the participant may be enrolled.
  • Pregnant at either Screening or Enrollment. Note: A documented negative pregnancy test performed by study staff is required for inclusion; however a self-reported pregnancy is adequate for exclusion from screening/enrollment into the study.
  • Diagnosed with urinary tract infection (UTI) at Screening or Enrollment. Note: Otherwise eligible participants diagnosed with UTI during screening will be offered treatment. If within the 45 day screening window treatment is complete and symptoms have resolved the participant may be enrolled.
  • Diagnosed with pelvic inflammatory disease, reproductive tract infection (RTI) or a sexually transmitted infection (STI) requiring treatment per current Centers for Disease Control and Prevention (CDC) guidelines (http://www.cdc.gov/std/treatment/) at Screening or Enrollment. Note: With the exception of gonorrhea, chlamydia, and/or syphilis, otherwise eligible participants diagnosed with a RTI during screening will be offered treatment. If within the 45 day screening window treatment is complete and symptoms have resolved the participant may be enrolled.
  • At Enrollment, has a clinically apparent Grade 1 or higher pelvic exam finding (observed by study clinician or designee) per the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 1.0, December 2004 (Clarification dated August 2009), Addendum 1, Female Genital Grading Table for Use in Microbicide Studies. 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.
  • At Screening, severe pelvic relaxation such that either the vaginal walls or the uterine cervix descend beyond the vaginal introitus with valsalva maneuver or has pelvic anatomy that compromises the ability to adequately assess vaginal safety
  • Has any other condition that, in the opinion of the IoR/designee, would preclude informed consent, make study participation unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving study objectives
