Participation Criteria
Eligibility Criteria
Ages Eligible for Study
- Adult
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Assigned female sex at birth.
- Able and willing to provide written informed consent to be screened for and enrolled in MATRIX-003 in one of the study languages.
- Able and willing to provide adequate contact/locator information.
Able and willing to comply with all protocol requirements, including:
- Abstaining from other intravaginal products or practices for the duration of the study.
- Abstaining from penetrative vaginal intercourse (i.e., oral-, digital-, penile-penetration) for the first 14 days of each product use period.
- Refraining from participation in other research studies involving drugs, medical devices, vaginal products, or vaccines starting 2 weeks before the Screening Visit and for the duration of the study, or in observational or qualitative studies for the duration of the study, unless approved by the Protocol Safety Review Team.
- Reliable access to a private phone for scheduled phone contacts.
- HIV-uninfected based on testing performed at Screening and Enrollment.
- Per participant report, must be either not currently sexually active or in a mutually monogamous relationship with only one partner who is not known to be HIV positive or to currently have a sexually transmitted infection.
- Negative urine pregnancy test at Screening and Enrollment.
- Participants over the age of 21 (inclusive) must have documentation of a Grade 0 Pap smear within the past 3 years prior to Enrollment, or a Grade 1 Pap smear at Screening with no treatment required.
Protected from pregnancy starting at least 2 weeks before Screening and continuing for the duration of study participation by an effective contraceptive method; effective methods include:
- Hormonal methods except vaginal rings
- Copper intrauterine device
- Sterilization of participant or (if applicable) sterilization of monogamous partner
- Correct and consistent condom use at study entry, and agrees to use site-provided condoms during study (for US site only)
Inclusion Criteria for sexual partner in-depth interview subset:
- Identifies as a sexual partner of a MATRIX-003 participant.
- Identified by participant as a sexual partner during MATRIX-003 for whom the participant has given permission to contact.
- Able and willing to provide written informed consent in one of the study languages.
- Able and willing to complete the required study procedures.
- Must be 18 years old or above at the time of their study participation.
Exclusion Criteria:
Per participant report at Screening and Enrollment, intends to do any of the following during the study participation period:
- Become pregnant.
- Breastfeed.
- Relocate away from the study site.
- Travel away from the study site for a time period that would interfere with product resupply and/or study participation.
- Positive HIV test at Screening or Enrollment.
- Positive test for Trichomonas vaginalis, Neisseria gonorrhea, Chlamydia trachomatis, or Treponema pallidum (Syphilis) at Screening and (per participant report) treated for potential sexually transmitted infection within past 12 months.
- Diagnosed with urinary tract infection, pelvic inflammatory disease, or reproductive tract infection requiring treatment at Enrollment.
Note: Otherwise eligible participants diagnosed during screening with a urinary tract infection, symptomatic yeast infection or symptomatic bacterial vaginosis infection are offered treatment. If treatment is completed and symptoms have resolved within 45 days of obtaining informed consent for screening, the participant may be enrolled.
- Clinically apparent Grade 2 or higher pelvic exam finding at Enrollment.
Note: Otherwise eligible participants with exclusionary pelvic exam findings at Screening may be enrolled/randomized if treatment is completed at least 7 days prior to enrollment and findings have improved to a non-exclusionary severity grading or resolved by the time of enrollment. Spotting/bleeding will be considered exclusionary only if greater than what would be expected from contraceptive use.
Participant report and/or clinical evidence of any of the following:
- Known adverse reaction to silicone (ever).
- Use of diaphragm, NuvaRing, or spermicide for contraception starting 2 weeks prior to Screening through Enrollment.
- Use of any of the following in the past 12 months: stimulants (cocaine [including crack], methamphetamine, or non-physician prescribed pharmaceutical-grade stimulants), or inhaled nitrates, or illicit injection drug use of any kind.
- Prior use of post-exposure prophylaxis or oral pre-exposure prophylaxis (including Emtricitabine/tenofovir) in the past 4 weeks or any prior use of long-acting systemic pre-exposure prophylaxis (including cabotegravir or islatravir).
- Antibiotic, steroid, or antifungal (oral or intravaginal) therapy within 14 days of Enrollment.
- Hysterectomy.
- Gynecologic or genital procedure (e.g., tubal ligation, dilation and curettage, piercing, Intrauterine device insertion or removal, colposcopy) within 21 days prior to Enrollment.
- At Screening or Enrollment, as determined by the Investigator of Record/designee, has 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:
- Grade 2 or higher Aspartate aminotransferase, alanine transaminase, creatinine, or Hemoglobin.
- Has any other condition that, in the opinion of the Investigator of Record/designee, would preclude informed consent, make study participation unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the study objectives.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Sequence: Placebo Intravaginal Ring A followed by Placebo Intravaginal Ring B
Placebo Intravaginal Ring A will be inserted and used for 28 days, Ring A will be removed and followed by no intravaginal ring use for 7-21 days.
Then Placebo Intravaginal Ring B will be inserted and used for 28 days.
|
Placebo Intravaginal Ring A consists of a flexible lavender silicone scaffold, with an outer diameter of 55 mm and a durometer value of 40A (Shore A hardness scale).
The ring holds two blank grey cassettes.
Placebo Intravaginal Ring B consists of a flexible lavender silicone scaffold, with an outer diameter of 55 mm and a durometer value of 50A (Shore A hardness scale).
The ring holds two blank grey cassettes.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants Preferring to Use Placebo Intravaginal Ring A versus Ring B
Time Frame: Through study completion, approximately 11 weeks
|
Number of participants that report a preference to use placebo intravaginal Ring A versus Ring B
|
Through study completion, approximately 11 weeks
|
Mean Satisfaction with Placebo Intravaginal Ring Use
Time Frame: Through study completion, approximately 11 weeks
|
Satisfaction will be assessed using a 10-point Likert scale with 0 being the least satisfied and 10 being the most satisfied
|
Through study completion, approximately 11 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants with Genitourinary Grade 2 or Higher Adverse Events
Time Frame: Through study completion, approximately 11 weeks
|
Number of participants with genitourinary Grade 2 or higher adverse events deemed related to placebo intravaginal ring use
|
Through study completion, approximately 11 weeks
|
Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean Change in Nugent Score
Time Frame: Through study completion, approximately 11 weeks
|
Mean change in the Nugent score as determined from vaginal smears.
Nugent scores range from 0 to 10; 0 indicates a Lactobacillus-dominant microbiome while a score of 10 indicates a microbiome dominated by bacterial vaginosis-associated bacteria.
Mean change will be assessed from pre-insertion and after 28 days of placebo intravaginal ring use for both rings A and B
