About this study

Official title: A DOUBLE-BLIND, RANDOMIZED, PLACEBO-CONTROLLED PHASE I/II TRIAL TO EVALUATE THE SAFETY OF DAPIVIRINE GEL 4759, 0.05% 2.5g AND DAPIVIRINE GEL 4789, 0.05% 2.5g FORMULATIONS AS COMPARED TO THE VAGINAL HEC-BASED UNIVERSAL PLACEBO GEL, 2.5g IN HEALTHY HIV-NEGATIVE WOMEN

A double-blind, randomized, placebo-controlled Phase I/II trial to evaluate the safety of dapivirine Gel 4759, 0.05% 2.5 g and dapivirine Gel 4789, 0.05% 2.5 g formulations as compared to the vaginal HEC-based Universal placebo gel, 2.5 g in healthy HIV-negative women

Read the detailed description

This was a double-blind, randomized, placebo-controlled trial, to be conducted over 10 months at five research centers in the USA among 180 healthy, sexually active women, to assess the safety and acceptability of dapivirine Gel 4759, 0.05% 2.5 g, and dapivirine Gel 4789, 0.05% 2.5 g, both vaginal microbicides containing dapivirine, compared to the vaginal HEC-based Universal placebo gel, 2.5 g, containing no active ingredient, used once daily for a period of 12 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The Percentage of Women With the Composite Endpoint of Abnormal Safety Findings.

    A composite endpoint was defined as the percentage of participants with any post-baseline abnormal finding from pelvic/speculum examination, colposcopy finding, STI diagnoses, laboratory test of DAIDS grade 3 or higher and any product-related AE.

    DAIDS severity grades are defined as follows:

    Grade 1 = mild Grade 2 = moderate Grade 3 = severe Grade 4 = potentially life-threatening Grade 5 = death

    Measured: 12 weeks

Secondary outcomes (7)
  1. Changes in the Vaginal Flora

    Cervicovaginal fluid specimens will be obtained to determine vaginal flora before first gel application and at Visits 3, 5, and 6. Appropriate statistical analyses incorporating repeated measures will be used to assess the changes in the vaginal flora in women using Dapivirine Gel 4759, 0.05% 2.5g, Dapivirine Gel 4789, 0.05% 2.5g or the vaginal HEC-based universal placebo gel, 2.5g.

    Nugent scores were used to assess changes in vaginal flora, and were categorized into three levels: (1) negative for BV (score: 0-3); (2) altered vaginal flora (score: 4-6); and (3) BV (score: 7-10).

    Measured: 16 weeks

  2. The Distribution of Dapivirine Levels Observed in Plasma Samples at Each Specified Time Point

    Dapivirine levels observed in plasma will be summarized using simple descriptive statistics.

    Measured: 12 weeks

  3. The Adherence to Once Daily Application of a Vaginal Microbicide Gel Over a 12-week Period in Healthy, Sexually Active, HIV-negative Women

    Adherence is defined as the percentage of participants who used the gel each day of the preceding 14 days, based on participant self reports.

    Measured: 12 weeks

  4. Changes in the Vaginal pH

    Cervicovaginal fluid specimens will be obtained to determine vaginal pH before first gel application and at screening, enrolment and visit 5 (week 12). Appropriate statistical analyses incorporating repeated measures will be used to assess the changes in the vaginal pH in women using Dapivirine Gel 4759, 0.05% 2.5g, Dapivirine Gel 4789, 0.05% 2.5g or the vaginal HEC-based universal placebo gel, 2.5g.

    Measured: 12 weeks

  5. The Distribution of Dapivirine Levels Observed in Vaginal Fluid at Each Specified Time Point.

    The distribution of dapivirine levels observed in each type of sample will be summarized using simple descriptive statistics. In addition, the proportion of women with detectable dapivirine concentrations will be calculated for each type of sample at each collection time point. Exploratory analyses of dapivirine concentration data will also be performed to take into account information reported in a diary regarding menses and tampon use throughout the trial.

    Measured: 12 weeks. Measured at 2, 4, and 8 weeks post-enrolment and at one of these at week 12; 24, 48, or 72 hours after gel discontinuation. (Participants were randomized to have vaginal fluid samples collected at one of these visits (5a, 5b, or 5c).

  6. The Distribution of Dapivirine Levels Observed in Vaginal Tissue at Each Specified Time Point.

    The distribution of dapivirine levels observed in vaginal tissue sample will be summarized using simple descriptive statistics.

    Measured: 12 weeks. Measured at 2, 4, and 8 weeks post-enrolment and at one of these at week 12; 24, 48, or 72 hours after gel discontinuation. (Participants were randomized to have vaginal fluid samples collected at one of these visits (5a, 5b, or 5c).

  7. Acceptability of Once Daily Application of a Vaginal Microbicide Gel Over a 12-week Period in Healthy, Sexually Active, HIV-negative Women

    Acceptability was assessed as the percentage of participants at week 12 who were willing to use the gel every day if proven to prevent HIV.

    Measured: 12 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing dapivirine 4789 and dapivirine gel 4759 in people with HIV-1 Infections, run by International Partnership for Microbicides, Inc. at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 23 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Oct 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Percentage of Women With the Composite Endpoint of Abnormal Safety Findings. (time frame: 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Oct 2022; AzTrials last refreshed its copy on 7 Nov 2026.
