NCT05059418

Brief Summary

The first part of this study is to optimize diagnostic criteria for BMS, i.e. not a clinical trial, and will not be covered in this application. The second part will compare topical treatment with clonazepam, capsaicin and placebo in a n-of-1 study design regarding effects of pain, pain-related disability, somatosensory changes in the trigeminal nerve and patient experience in patients with primary BMS or other oral mucosal pain. The patients will be treated for two weeks with each drug, with a one-week wash-out period in between. After the last washed-out period, the patients will be able to chose the treatment that they prefer the most and continue with that treatment during 6 months.

Outcome Measures

Primary Outcomes (6)

  • Pain intensity

    Overall oral mucosa pain intensity. Will be assessed using the subscale "Characteristic pain intensity" (three numerical rating scales 0 - 10 assessing current pain. intensity as well as worst and average pain intensity during the last two weeks) in the Graded Chronic Pain Scale

    Point measurement, will be assessed immediately before start of treatment

  • Pain intensity

    Overall oral mucosa pain intensity. Will be assessed using the subscale "Characteristic pain intensity" (three numerical rating scales 0 - 10 assessing current pain. intensity as well as worst and average pain intensity during the last two weeks) in the Graded Chronic Pain Scale

    Point measurement, will be assessed 10 days after treatment start for each treatment period.

  • Pain intensity

    Overall oral mucosa pain intensity. Will be assessed using the subscale "Characteristic pain intensity" (three numerical rating scales 0 - 10 assessing current pain. intensity as well as worst and average pain intensity during the last two weeks) in the Graded Chronic Pain Scale

    Point measurement, will be assessed the day after each treatment period is finished (22 days after start of each treatment)

  • Patient satisfaction

    Patient satisfaction with the treatment tested. Will be assessed using a numerical rating scale 0 - 10 where 0 = very dissatisfied and 10 = very satisfied.

    Point measurement, will be assessed immediately before start of treatment

  • Patient satisfaction

    Patient satisfaction with the treatment tested. Will be assessed using a numerical rating scale 0 - 10 where 0 = very dissatisfied and 10 = very satisfied.

    Point measurement, will be assessed 10 days after treatment start for each treatment period.

  • Patient satisfaction

    Patient satisfaction with the treatment tested. Will be assessed using a numerical rating scale 0 - 10 where 0 = very dissatisfied and 10 = very satisfied.

    Point measurement, will be assessed the day after each treatment period is finished (22 days after start of each treatment)

Secondary Outcomes (1)

  • Pain-related disability

    Point measurement, will be assessed immediately before start of treatment as well as one, two and three weeks after treatment start.
