About this study

Official title: A Phase I, Open-Label, Randomized, Crossover Trial to Investigate the Relative Bioavailability of the 25 mg Dapivirine Vaginal Ring-004 Inserted Every 30 Days and 100 mg DPV Ring-008 Inserted for 90 Days in Healthy Female Participants

A Phase I, Open-Label, Randomized, Crossover Trial to Investigate the Relative Bioavailability of the 25 mg Dapivirine Vaginal Ring-004 inserted every 30 days and 100 mg Dapivirine Vaginal Ring-008 inserted for 90 days in Healthy Female Participants

Read the detailed description

IPM 054 is a Phase I, open-label, randomized, crossover trial to determine the relative bioavailability in plasma and vaginal fluid of two formulations of the dapivirine vaginal ring in HIV-negative women. The trial will compare the dapivirine concentrations achieved in plasma and vaginal fluid over all timepoints for each 90-day use period in a two-period, two-sequence, crossover design.

Participants will be randomized to one of two treatment sequences (AB or BA). During two consecutive 90-day treatment periods, the participants will receive each of the following treatments according to their assigned treatment sequence. The treatment periods will be separated by a 28-day washout period.

Treatment Sequence 1:

  • 25 mg dapivirine ring (Ring-004) for 90 days (replaced every 30 days) (Treatment A), followed by the 100 mg dapivirine ring (Ring-008) used continuously for 90 days (Treatment B)

Treatment Sequence 2:

  • 100 mg dapivirine ring (Ring-008) used continuously for 90 days (Treatment B), followed by the 25 mg dapivirine ring (Ring-004) for 90 days (replaced every 30 days) (Treatment A)

What is being measured

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

  1. To determine the relative bioavailability of Dapivirine Vaginal Ring-008 compared to Dapivirine Vaginal Ring-004 by comparison of dapivirine plasma pharmacokinetic parameters.

    Dapivirine concentrations in plasma, measured at specified timepoints during each 90-day ring use period.

    Measured: during a 90 day use period

Secondary outcomes (4)
  1. To further characterize the pharmacokinetic profile of Dapivirine Vaginal Ring-008 compared to Dapivirine Vaginal Ring-004 in vaginal fluid

    Dapivirine concentrations in vaginal fluid, measured at specified timepoints during each 90-day ring use period, and for 1 day following ring removal. Vaginal fluid samples will be collected using tear test strips at the location of the cervix.

    Measured: during each 90 days ring use period

  2. To evaluate the incidence of Grade 1 or higher genitourinary treatment-emergent adverse events and the incidence of Grade 3 or higher treatment-emergent adverse events of the two dapivirine vaginal ring formulations used continuously for 90 days

    Evaluating the incidence of treatment-emergent adverse events with severity grades as defined by the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1, July 2017, and/or Addendum 1 (Female Genital Grading Table for Use in Microbicide Studies [Dated November 2007]).

    Measured: during each 90 days ring use period

  3. To assess the effects on vaginal flora when using Dapivirine Vaginal Ring-004 and Dapivirine Vaginal Ring-008 formulations used continuously for 90 days

    Assessing the effects by evaluating changes in vaginal pH from baseline and the incidence of bacterial vaginosis, assessed by Nugent scores of ≥ 7, determined from vaginal specimens collected for Gram staining.

    Measured: during each 90 days ring use period

  4. To characterize the vaginal microenvironment over the course 90 days of ring use.

    The amount of dapivirine released over three 30-day periods (ie, 90 days) for Ring-004 and over 90 days for Ring-008. Residual dapivirine levels in used rings

    Measured: during a 90 day use period

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing dapivirine in people with HIV Infections, run by International Partnership for Microbicides, Inc. at 1 site in South Africa.

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 18 inclusion and 9 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 3 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Africa. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To determine the relative bioavailability of Dapivirine Vaginal Ring-008 compared to Dapivirine Vaginal Ring-004 by comparison of dapivirine plasma pharmacokinetic parameters. (time frame: during a 90 day use period). 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 3 Jul 2024.
