Study summary

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)

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Interventions

06

What researchers measure

Primary outcomes

  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.

    Time frame: during a 90 day use period

Secondary outcomes

  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.

    Time frame: 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 \[Dated November 2007\]).

    Time frame: 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.

    Time frame: 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

    Time frame: during a 90 day use period
