About
This study will evaluate the safety of the dapivirine vaginal ring when inserts once every 4 weeks in postmenopausal women over 12 weeks of product use.
Full description
Dapivirine, a non-nucleoside reverse-transcriptase inhibitor (NNRTI), is a substituted diamino- pyrimidine (DAPY) derivative with potent antiviral activity against HIV-1. Dapivirine is chemically described as 4-[[4-[(2,4,6-trimethylphenyl)amino]-2- pyrimidinyl]amino]benzonitrile.6 The dapivirine matrix VR is a flexible ring containing 25 mg of drug substance dispersed in a platinum-catalyzed-cured silicone matrix. Dapivirine is known to be well-suited for delivery via VR, as evidenced by favorable safety and pharmacokinetic data to date described below.

Inclusion criteria
Age 45 through 65 years (inclusive) at Screening, verified per site SOPs
Per participant report, postmenopausal at Screening, defined as amenorrhoeic for the past 12 months (minimum) or at least 6 months status post-bilateral oophorectomy
Follicle-stimulating hormone (FSH) level at 40 mIU/ml or higher at Screening
Able and willing to provide written informed consent to be screened for and enrolled in MTN-024/IPM 031
Able to communicate in spoken and written English
Able and willing to comply with all study procedural requirements
Willing to only use study provided and/or approved vaginal products throughout the duration of study participation.
Willing to abstain from inserting study approved lubricant into the vagina for 72 hours prior to each visit
Willing to abstain from vaginal intercourse for 72 hours prior to each visit
In general good health as determined by the Investigator of Record (IoR)/designee at Screening and Enrollment
Able and willing to provide adequate locator information, as defined in site SOPs
HIV-uninfected based on testing performed at Screening (per protocol algorithm in Appendix II)
Per participant report at Screening and Enrollment, agrees to use male latex condoms for sexual intercourse
Per participant report at Screening and Enrollment, 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, topical or systemic hormone replacement therapy, including vaginal estrogens, and/or hormonal contraceptives, vaginal medications, menstrual cups, cervical caps (or any other vaginal barrier method), vaginal douches, lubricants and moisturizers, sex toys (vibrators, dildos, etc.), for the duration of the study participation.
Note: Use of study approved lubricant is permitted.
At Screening and Enrollment, agrees not to participate in other research studies involving drugs, medical devices, vaginal products, or vaccines for the duration of study participation
Participants in the biopsy subset must also meet the following criteria at Screening to be eligible for inclusion:
Willing to abstain from inserting anything into the vagina for 72 hours following the collection of biopsies, including abstaining from vaginal intercourse
Anatomy sufficient for the collection of cervical biopsies
Exclusion criteria
Per participant report at screening:
Pregnant at screening Note: A documented negative pregnancy test performed by study staff is required for inclusion; however a self-reported pregnancy is adequate for exclusion from the study.
Diagnosed with urinary tract infection (UTI) at Screening or Enrollment Note: Otherwise eligible participants diagnosed with UTI during screening are offered treatment and may be enrolled after completing treatment and all symptoms have resolved.
If treatment is completed and symptoms have resolved within 45 days of obtaining informed consent for screening, the participant may be enrolled.
Diagnosed with pelvic inflammatory disease, an STI or reproductive tract infection (RTI) requiring treatment per current Centers for Disease Control and Prevention (CDC) guidelines at Screening or Enrollment Note: Otherwise eligible participants diagnosed during screening with pelvic inflammatory disease or STI/RTI requiring treatment per CDC guidelines - other than asymptomatic bacterial vaginosis (BV) and asymptomatic candidiasis - are offered treatment and may be enrolled after completing treatment and all symptoms have resolved. If treatment is completed and symptoms have resolved within 45 days of obtaining informed consent for screening, the participant may be enrolled. Genital warts requiring treatment also must be treated prior to Enrollment. Genital warts requiring therapy are defined as those that cause undue burden or discomfort to the participant, including bulky size, unacceptable appearance, or physical discomfort.
Has a clinically apparent Grade 2 or higher pelvic exam finding (observed by study staff) at Screening or Enrollment, as 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 bleeding associated with speculum insertion and/or specimen collection judged to be within the range of normal according to the clinical judgment of the Investigator of Record (IoR)/designee is considered expected non-menstrual bleeding and is not exclusionary.
Note: Otherwise eligible participants with exclusionary pelvic exam findings may be enrolled/randomized after the findings have improved to a non-exclusionary severity grading or resolved. If improvement to a non-exclusionary grade or resolution is documented within 45 days of providing informed consent for screening, the participant may be enrolled.
Participant report and/or clinical evidence of any of the following:
As determined by the IoR/designee, any significant uncontrolled active or chronic cardiovascular, renal, liver, hematologic, neurologic, gastrointestinal, psychiatric, endocrine, respiratory, immunologic disorder or infectious disease
Has any of the following laboratory abnormalities at Screening Visit:
Note: Women with a documented normal result within the 12 months prior to Enrollment need not have a Pap smear during the screening period. Women with a Grade 1 abnormal Pap smear can be enrolled upon completion of the initial phase of evaluation if no current treatment is indicated (based on local standard of care for management of abnormal cervical cytology). Need for a repeat Pap within 6 months does not preclude Enrollment prior to that result becoming available. If the participant has had a hysterectomy for reasons not related to cervical dysplasia, a Pap smear need not be performed.
Has any other condition that, in the opinion of the IoR/designee, would preclude informed consent, make study participation unsafe, complicate the interpretation of study outcome data, or otherwise interfere with achieving the study objectives *Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 1.0, December, 2004 (Clarification dated August 2009) **Female Genital Grading Table for Use in Microbicide Studies Addendum 1 to the Division of AIDS (DAIDS) Table for Grading Adult and Pediatric Adverse Events, Version 1.0, December 2004 (Clarification dated August 2009)
