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

  • Post-menarche woman aged 18 to 50 years old (inclusive),
  • With suspected Bacterial Vaginosis (BV) and/or Vulvovaginal Candidiasis (VVC), presenting symptoms of acute vaginal infection
  • No and relevant abnormalities of medical history (including mental disorders) or physical examination,
  • Able and willing to participate to the trial by complying with the protocol procedures as evidenced by her dated and signed form,

Exclusion criteria

Exclusion Criteria:

  • Other already diagnosed or suspected infectious causes of bacterial vaginal infection (e.g., Trichomonas vaginalis, Chlamydia trachomatis, Neisseria gonorrhoeae) within 1 month
  • Current herpes simplex flare-up in the genital area,
  • Vulvar condyloma due to the human papilloma virus;
  • Vulvar dermatoses (e.g.: psoriasis or lichenification);
  • Clinical diagnosis of BV or VVC within 4 months;
  • Treatment with any antibiotic or antifungal therapy (local or systemic) within 2 months, regardless of the indication;
  • Treatment with any local treatment (probiotics, antiseptic, etc.) within 1 month, regardless of the indication;
  • Participant using any intravaginal product (local [spermicide, hormonal ring], moisturizer, tampon, intimate hygiene product, etc.);
  • Participant with a chronic disease or condition or treatment known to impact the immune system, including auto-immune disease, diabetes, cancer, renal failure, etc.
  • Pregnant or breastfeeding patient or intending to become pregnant within 1 month ahead, or having given birth within 3 months;
  • Participant in perimenopause, i.e. aged 45 years or more, with irregular menstrual cycles that could lead to a suspicion of menopause;
  • With a known or suspected food allergy or intolerance or to any of the trial intervention ingredient;
Terms in these criteria, in plain language(4)

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
