Inclusion criteria

  • Ability to confirm voluntary participation and agree to all trial purposes by signing and dating the forms;
  • Age greater than or equal to 12 years;
  • Minor recurrent aphthous ulceration with onset of symptoms within 48 hours;
  • Moderate to severe baseline pain, with VAS ≥ 4 (EVA scale).

Exclusion criteria

Exclusion Criteria:

  • Any clinical findings that, in the judgment of the investigator, may interfere with the safety of research participants;
  • Participants diagnosed with: Behcet's disease, rheumatoid arthritis, systemic lupus erythematosus, reactive arthritis, Reiter's syndrome, Crohn's disease, ulcerative colitis);
  • Participants with diseases that affect healing (e.g. diabetes);
  • participants;
  • Participants with aphthous herpetiform ulceration or major aphthous ulceration;
  • Participants using medication to treat oral ulcerations (systemic or local);
  • Participants who used analgesics or anti-inflammatory drugs in the 6 hours prior to the beginning of the study;
  • Participants who used systemic antibiotics in the 2 weeks prior to the beginning of the study;
  • Participants using medications that can confuse pain assessment (psychotropics, antidepressants and sedative-hypnotics), except when on a stable dose for at least 30 days prior to the screening visit, and the dose cannot be changed during the clinical trial;
  • Participants with current smoking habits.
  • Participants who are pregnant, breastfeeding or planning to get pregnant or female participants with the potential to become pregnant who are not using a reliable method of ;
  • Known to the formula components used during the clinical trial;
  • Participants with current or medical history of cancer in the last 5 years;
  • Participants who participated in other research protocol in the last 12 months, unless the investigator judges that there may be a direct benefit to it.
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.

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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.

    Three applications per day or more in case of pain, not exceeding six applications per day. The number of drops varies according to the ulcer diameter: 1 to 3 mm: 1 drop; 3 to 6 mm: 2 drops; greater than 6 mm: 3 drops.

    Drug: BALI association

  • Placebo comparator
    PLACEBO

    Three applications per day or more in case of pain, not exceeding six applications per day. The number of drops varies according to the ulcer diameter: 1 to 3 mm: 1 drop; 3 to 6 mm: 2 drops; greater than 6 mm: 3 drops.

    Drug: Placebo

Interventions

  • DrugBALI association

    BALI association oral suspension, 25 mg + 25 mg + 15 mg, oral. Three applications per day or more in case of pain, not exceeding six applications per day.

  • DrugPlacebo

    Placebo. Three applications per day or more in case of pain, not exceeding six applications per day.

What researchers measure

Primary outcomes

  1. To assess the reduction in pain intensity after 3 days of treatment.

    Difference in pain intensity after 3 days of treatment compared to baseline. Pain intensity will be evaluated by the Visual Analogue Scale (VAS). The VAS consists of a 10 cm line, with two end points representing 0 ("no pain") and 10 (pain as bad as it could possibly be").

    Time frame: 3 days

Secondary outcomes

  1. To assess the reduction in pain intensity after the first application.

    Difference in pain intensity 15 minutes after the first application of the medication compared to baseline, measured by the VAS scale. The VAS consists of a 10 cm line, with two end points representing 0 ("no pain") and 10 (pain as bad as it could possibly be").

    Time frame: 15 minutes

  2. To assess the reduction in pain intensity during the treatment.

    Difference in pain intensity after 5 and 7 days of treatment compared to baseline, measured by the VAS scale. The VAS consists of a 10 cm line, with two end points representing 0 ("no pain") and 10 (pain as bad as it could possibly be").

    Time frame: 5 and 7 days

  3. Percentage of participants healed during treatment.

    Percentage of participants healed after 3, 5, and 7 days of treatment, defined as ulcer diameter = 0 mm and pain intensity = 0, measured by the Likert scale. Likert scale is a five point scale: 0 = no pain and 4 = pain as bad as it could possibly be".

    Time frame: 3, 5 and 7 days

  4. Percentage of participants with no pain during treatment.

    Percentage of participants with no pain after 3, 5, and 7 days of treatment, measured by the Likert scale. Likert scale is a five point scale: 0 = "no pain" and 4 = "pain as bad as it could possibly be".

    Time frame: 3, 5 and 7 days

  5. To assess the percentage change in pain intensity from baseline during treatment.

    Pain intensity will be evaluated by the VAS scale.The following calculations will be performed: ((D3, D5 or D7 - V0) / baseline) ×100%. The VAS consists of a 10 cm line, with two end points representing 0 ("no pain") and 10 (pain as bad as it could possibly be").

    Time frame: 3, 5 and 7 days
