About this study

Official title: A Double-Blind, Randomized Trial of Monthly Treatment With Topical Metronidazole and Miconazole Co-formulated Vaginal Suppositories Versus Placebo for Preventing Vaginal Infections in HIV-seronegative Women

This research study is about vaginal infections such as bacterial vaginosis, yeast infections, and trichomoniasis. Usually, these infections can be treated with medication, but sometimes they come back after treatment. Researchers want to know if using vaginal suppositories can decrease the risk of vaginal infections. Participants will include 234 women who are sexually active (greater than or equal to 4 episodes of sex with men during the past month), HIV-negative, 18 to 45 years old, with bacterial infection [vaginosis and/or vulvovaginal candidiasis (VVC) and/or Trichomonas vaginalis] detected by laboratory testing at a screening visit. Women will receive vaginal suppositories containing drug or inactive ingredients (placebo). Participation in the study will be about 12 months. Study procedures include: urine and blood tests, physical exams, and questionnaires.

Read the detailed description

Vaginal infections including bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), and Trichomonas (T.) vaginalis are common and have been associated with increased risk of HIV and other sexually transmitted infections (STIs) in multiple prospective studies. Effective interventions for prevention of vaginal infections could substantially reduce the risk of HIV and other STIs in women. A recently completed trial has demonstrated that monthly periodic presumptive treatment (PPT) can reduce vaginal infections and promote Lactobacillus colonization. However, the oral regimen of metronidazole 2 grams plus fluconazole 150 mg was not sufficiently effective to warrant moving to Phase III HIV/STI prevention trials using this intervention. The identification of more efficacious regimens for reducing vaginal infections is a crucial step towards the development of inexpensive, female-controlled, non-coitally dependent HIV/STI risk reduction interventions for women. There is growing evidence that higher doses and longer courses may be more effective for treatment of vaginal infections than single-dose therapy. The overall goal of this protocol is to conduct a randomized, double-blind, placebo-controlled trial to test the efficacy of monthly PPT with topical metronidazole 750 mg plus miconazole 200 mg (co-formulated suppositories) versus matching placebo suppositories nightly for five nights each month for reducing the rates of BV and VVC among HIV-seronegative women. This regimen could produce sufficient reductions in vaginal infections to support its use in Phase III HIV and STI prevention trials. The study participants will include 234 women who are sexually active (greater than or equal to 4 episodes of heterosexual intercourse during the past month), HIV-seronegative, 18 to 45 years old, with BV and/or VVC and/or T. vaginalis detected by laboratory testing at a screening visit. There will be two study arms. The treatment arm (117 subjects) will receive PPT with intravaginal metronidazole 750 mg plus miconazole 200 mg (co-formulated suppositories) for five consecutive nights each month. The placebo arm (117 subjects) will receive PPT with identical placebo intravaginal suppositories for five consecutive nights each month. Individual participants will be in the study for one year.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Neo-Penotran® Forte (active ingredient Metronidazole & Miconazole Nitrate)Drug

    Neo-Penotran® Forte (active ingredient Metronidazole \& Miconazole Nitrate), co-formulated vaginal suppositories containing metronidazole 750 mg with miconazole 200 mg and excipients (Witepsol S 55). Witepsol S 55 is a hard fat suppository base. Such bases consist mainly of triglyceride esters of the higher saturated fatty acids along with varying proportions of mono- and diglycerides. 117 subjects receive nightly for 5 consecutive night each month.

  • PlaceboDrug

    Placebo vaginal suppositories, identical in appearance to the active product; contains Witepsol S 55, Titanium Dioxide and D+C yellow #10 with no metronidazole or miconazole.117 subjects receive nightly for 5 consecutive nights each month.

What is being measured

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

  1. Efficacy of Monthly Periodic Presumptive Treatment (PPT) Using Metronidazole With Miconazole Intravaginal Suppositories Versus Matching Placebo Nightly for Five Nights Each Month for Preventing Vulvovaginal Candidiasis (VVC).

    Percentage of follow-up visits (Months 2, 4, 6, 8, 10, 12) positive for VVC based on the presence of fungal elements (pseudohyphae, blastoconidia, or both) on vaginal saline wet mount plus a positive culture showing yeast on Sabouraud's agar.

    Measured: Months 2, 4, 6, 8, 10, and 12.

  2. Efficacy of Monthly Periodic Presumptive Treatment (PPT) Using Metronidazole With Miconazole Intravaginal Suppositories Versus Matching Placebo Nightly for Five Nights Each Month for Preventing Bacterial Vaginosis (BV).

    Percentage of follow-up visits (Months 2, 4, 6, 8, 10, 12) positive for BV as determined by applying standard microscopic scoring criteria (Nugent's criteria) to vaginal Gram stained slides. BV is diagnosed when the score is greater than or equal to 7.

    Measured: Months 2, 4, 6, 8, 10, and 12.

Secondary outcomes (2)
  1. Efficacy of Monthly Periodic Presumptive Treatment (PPT) Using Metronidazole With Miconazole Intravaginal Suppositories Versus Placebo for Preventing Any Vaginal Infection (a Combined Endpoint Including BV, VVC, and Trichomonas Vaginalis Infection).

    Percentage of follow-up visits (Months 2, 4, 6, 8, 10, 12) positive for any of three vaginal infections (BV, VVC, Trichomonas vaginalis infection).

    Measured: Months 2, 4, 6, 8, 10, and 12.

  2. Efficacy of Monthly Periodic Presumptive Treatment (PPT) Using Metronidazole With Miconazole Intravaginal Suppositories Versus Matching Placebo Nightly for Five Nights Each Month for Preventing BV by Clinical Criteria (Amsel's Criteria).

    Percentage of follow-up visits (Months 2, 4, 6, 8, 10, 12) positive for BV by clinical criteria (Amsel's criteria).

    Measured: Months 2, 4, 6, 8, 10, and 12.

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 13 inclusion and 24 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 6 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Kenya, 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 phase mean?

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 26 Sep 2014). 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?

Efficacy of Monthly Periodic Presumptive Treatment (PPT) Using Metronidazole With Miconazole Intravaginal Suppositories Versus Matching Placebo Nightly for Five Nights Each Month for Preventing Vulvovaginal Candidiasis (VVC). (time frame: Months 2, 4, 6, 8, 10, and 12.). The study lists 2 primary outcomes in all. 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?
