About this study
Official title: Preparing for a Clinical Trial of Interventions to Maintain Normal Vaginal Microbiota for Preventing Adverse Reproductive Health Outcomes in Africa
A pilot randomized controlled clinical trial of intermittent use of two different vaginal lactobacilli-containing probiotics, and oral metronidazole, to prevent bacterial vaginosis recurrence.
Read the detailed description
This is a pilot study to prepare for larger clinical trials. Sixty-eight HIV-negative, non-pregnant, sexually active women aged 18-45 with bacterial vaginosis (BV, by modified Amsel criteria and/or Nugent score) and/or Trichomonas vaginalis (TV, on wet mount or by culture) will be treated using oral metronidazole for 7 days. After successful treatment, and when they are free of vaginal candidiasis, other curable sexually transmitted infections (STIs) and urinary tract infection (UTI)), they will be randomised to 4 different vaginal microbiome (VMB) maintenance interventions (17 per group) within 3 days of completing oral metronidazole treatment: 1) Behavioral 'vaginal practices cessation and safer sex' counselling only (control); 2) Behavioral counselling plus 500mg metronidazole pills twice per week for two months; 3) Behavioral counselling plus Ecologic Femi vaginal capsule, once per day for 5 days immediately after oral metronidazole treatment followed by thrice weekly, for two months; 4) Group 4: Behavioral counselling plus Gynophilus vaginal tablet, once every 4 days for two months. Vaginal probiotic use may be ceased temporarily during menstruation. Participants will be asked to adhere to the interventions for 2 months, and VMB assessments will take place before (screening and enrolment visits), during (Day 7, Month 1 and Month 2 visits), and after the interventions (Month 6 visit).

What is being measured
The primary outcome is the main question the study is designed to answer.
Bacterial Vaginosis (BV) Incidence by Modified Amsel Criteria
Modified Amsel criteria positive is at least 2 of 3 of the following positive: clue cells, vaginal pH, whiff test.
Modified intent-to-treat (ITT) analyses (women with Nugent 7-10 at enrollment excluded), using person-years (PY) at risk as denominator of each incidence rate.
Measured: 2 months (intervention period)
Bacterial Vaginosis (BV) Incidence by Nugent Scoring (Nugent 7-10)
The Nugent score is a scale from 0-10 based on visualisation of three different bacterial morphotypes on a Gram stained slide, but in the incidence rates, the variable was used as a binary variable: BV present (Nugent score 7-10) or absent (Nugent score 0-6). Modified intent-to-treat (ITT) analyses (women with Nugent 7-10 at enrollment excluded), using person-years (PY) at risk as the denominator for each incidence rate.
Measured: 2 months (intervention period)
Trichomonas Vaginalis (TV) Incidence by Culture
A swab was inoculated into an InPouch culture pouch, specifically designed for TV growth. The pouch was checked daily for five days to detect growth. The results was positive when growth detected and negative when no growth detected on the fifth day.
Intent-to-treat (ITT) analyses, using person-years (PY) at risk as the denominator for each incidence rate.
Measured: 2 months (intervention period)
Vaginal Candidiasis Incidence by Wet Mount Microscopy
A wet mount is a smear of vaginal fluid on a microscopy slide, which is examined under a microscope. Yeasts are visible without staining. The definition of vaginal candidiasis was any yeast visible on the wet mount. Symptomatic vaginal candidiasis was considered a safety outcome because treatment of bacterial vaginosis often results in vaginal candidiasis. Intent-to-treat (ITT) analysis with person-years (PY) at risk as the denominator of all incidence rates.
Measured: 6 months: 2 months intervention period plus 4 months after intervention cessation
Secondary outcomes (1)
Vaginal Microbiota Composition by Illumina HiSeq Sequencing: Lactobacillus Genus Concentration
The vaginal microbiota sequencing results are exploratory and full data can be found in a manuscript on the BioRxiv preprint server. The most important outcome is the concentration of Lactobacillus genus in vaginal samples taken at the end of the intervention period (M2 visit).
Measured: 2 months (intervention period)

Questions about this trial
What is this clinical trial studying?
A study testing Vaginal multiple lactobacilli-containing probiotic for prevention of BV recurrence, Prophylactic use of metronidazole pills (500 mg) and Vaginal Lcr35-containing probiotic for prevention of BV recurrence in people with Bacterial Vaginosis, run by Janneke van de Wijgert.
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 5 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 16 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
Yes. Results are posted in the registry (first posted 16 Jul 2019). 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?
Bacterial Vaginosis (BV) Incidence by Modified Amsel Criteria (time frame: 2 months (intervention period)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02459665, which also lists 3 linked publications.
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 16 Jul 2019.
