Study summary

This study aims to compare the efficacy and safety of the combination drug Clotrimazole+Lactulose with the monocomponent product Canesten® (clotrimazole) in adult women diagnosed with candidal vulvovaginitis. The primary objective was to confirm the superiority of the combination drug in terms of clinical and microbiological response on Day 25 of the study.

Read the detailed description

The study was conducted using an adaptive design to evaluate the impact of lactulose on the course of fungal infections. The primary endpoint was the proportion of patients achieving clinical and microbiological recovery on Day 25 (Visit 4). Secondary endpoints included assessment of symptom severity, changes in Lactobacillus content, and patient satisfaction with therapy. Participants were randomized into three groups: Clotrimazole+Lactulose, Canesten, and Lactulose.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Women aged 18 to 60 years.
  • Clinically and microbiologically confirmed diagnosis of candidal vulvovaginitis.
  • Negative pregnancy test at screening.
  • Agreement to use reliable throughout the study and for 30 days after its completion.
  • Signed .

Exclusion criteria

Exclusion Criteria:

  • Pregnancy or breastfeeding.
  • Diagnosed bacterial vaginosis.
  • Chronic inflammatory or atrophic diseases of the female genital organs.
  • History of malignant neoplasms.
  • Use of systemic antibiotics or antifungal drugs within 2 weeks prior to screening.
Terms in these criteria, in plain language(2)

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.

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.

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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 19, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
