Study Summary

Inherited Epidermolysis Bullosa (EB) is a disorder that causes skin fragility and blistering in skin and mucous membranes, including the mouth. Recurrent oral blisters and ulcer result in oral pain and discomfort.

Dentoxol® is a mouthrinse that has anti-inflammatory, antimicrobial and analgesic effects. It has significant potential to reduce EB related oral symptoms.

This study includes people living with Inherited Epidermolysis Bullosa aged 6 and above; and is aimed at determining the efficacy of two different dose regimens of Dentoxol mouthrinse in reducing oral symptoms.

Study Description

Inherited Epidermolysis Bullosa (EB) is a group of genetic disorders with skin fragility and blistering. In addition to the skin, it can affect the mucous membranes, causing oral symptoms including oral pain and discomfort due to recurrent oral blisters, ulcers and erosions. Dentoxol® is a proprietary mouthrinse that has anti-inflammatory, antimicrobial and analgesic effects. This three-pronged strategy therefore has significant potential to reduce EB related oral symptoms.

Preliminary reports of Dentoxol® mouthrinse have suggested that it is safe and effective in reducing the EB related oral symptoms.Therefore, a well-controlled Phase II study is now warranted.

This study will include people living with Inherited Epidermolysis Bullosa aged 6 and over, and seeks to determinate the efficacy of two different dose regimens of Dentoxol mouthrinse in reducing the symptoms mentioned above.

Methods: 100 subjects with EB will be recruited and will be given Dentoxol® mouthrinse for two periods of 6 weeks using different dose regimes.

Subjects will have a dose regimen assigned randomly, group A: first 6 weeks will be asked to rinse 5 times a day, followed by a 4 weeks washout period and the second 6 weeks period: twice a day. Group B: first 6 weeks 2 times a day, second 6 weeks period: 5 times a day, both with a 4 week washout period in between.

On week 0, 1, 3 and 6 of each regime patients living in the metropolitan area will be examined by the Oral Medicine specialist.
