Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: BNP105 (25 + 25 + 15) Up to 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: BNP105 (25 + 25 + 15)
BNP105 oral suspension, 25 mg + 25 mg + 15 mg, oral. Up to six applications per day.
|
| Placebo Comparator: Placebo Up to 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. |
Other: Placebo
Placebo. Up to six applications per day.

Outcome Measures
Primary Outcome Measures
- To assess the change in pain intensity after the first application. [3 and 10 minutes]
Difference in pain intensity 3 and 10 minutes after the first application of the medication compared to baseline, measured by the VAS scale. The VAS consists of a 100 mm line, with two end points representing 0 ("no pain") and 100 (Worst Possible Pain").
Secondary Outcome Measures
- To assess the change in pain intensity after 3 days of treatment. [3 days]
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 100 mm line, with two end points representing 0 ("no pain") and 100 (Worst Possible Pain").
- To assess the pain intensity daily after breakfast, lunch and dinner. [7 days]
Pain intensity will be evaluated daily after breakfast, lunch and dinner by the Numeric Pain Rating Scale (NPRS). The NPRS is an 11-point scale scored from 0-10 representing 0 ("no pain") and 10 (Worst Possible Pain").
- To assess the pain intensity daily at night. [7 days]
Pain intensity will be evaluated daily at night by the Numeric Pain Rating Scale (NPRS). The NPRS is an 11-point scale scored from 0-10 representing 0 ("no pain") and 10 (Worst Possible Pain").
- To assess the oral health-related quality of life [7 days]
The oral health-related quality of life will be evaluated daily at night by the adapted Oral Health Impact Profile (OHIP) questionary.
- Percentage of participants healed after 3 days of treatment. [3 days]
Percentage of participants healed after 3 days of treatment, defined as ulcer diameter = 0 mm and pain intensity = 0, measured by the VAS scale. The VAS consists of a 100 mm line, with two end points representing 0 ("no pain") and 100 (Worst Possible Pain").
- Percentage of participants with no pain after 3 days of treatment. [3 days]
Percentage of participants with no pain after 3 days of treatment, defined as pain intensity = 0, measured by the VAS scale. The VAS consists of a 100 mm line, with two end points representing 0 ("no pain") and 100 (Worst Possible Pain").
- Global assessment of treatment by participant after 3 days of treatment [3 days]
The global evaluation of the treatment after 3 days of treatment will be evaluated by the categorical scale of 5 points representing 0 = very bad, 1 = bad, 2 = indifferent, 3 = good and 4 = very good.

Age greater than or equal to 12 years;
-
One minor recurrent aphthous stomatitis with onset of symptoms within 48 hours;
-
Moderate to severe baseline pain, with VAS ≥ 60 mm (EVA scale 0-100 mm).
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 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;
