Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Hidracare powder is an unregistered product, consisting of two well-known mineral salts (magnesium chloride and magnesium sulfate) and two antioxidant, anti-inflammatory compounds (dimethyl sulfone (MSM) and alpha lipoic acid (ALA)) in a base of sodium bicarbonate, with xanthum gum added as a thickener. The composition of the active ingredients is:
Magnesium sulfate heptahydrate (51.02% w/w)
Magnesium chloride hexahydrate (26.18% w/w)
Dimethyl sulfone (15.71% w/w)
Alpha lipoic acid (0.52% w/w)

A few drops of Hidracare solution is to be applied topically twice a day to hidradenitis suppurativa lesions over 8 weeks. The areas treated should be moist, not wet.

Adherence to the investigational product will be determined by participant diary entries and the number of used and unused Hidracare powder sachets returned. As the amount of Hidracare topical solution used will vary depending on the number of lesions and how freely the solution is applied by each individual, any unused solution returned will suitable to determine compliance.

Summary
Brief summary
Hidracare, a topical solution, is a proposed treatment for mild to moderate hidradenitis suppurativa (HS), and this proof of concept study is designed to assess the safety and efficacy of Hidracare.

It is expected this topical solution will be beneficial in reducing the number of lesions in participants with mild HS. As Hidracare is not yet approved for marketing or evaluated through human clinical trials, no clinical experience of this specific investigational product is available. However, a literature review provides data demonstrating the safety and efficacy of the four active ingredients in Hidracare (magnesium sulfate heptahydrate, magnesium chloride hexahydrate, alpha lipoic acid and dimethyl sulfone).

This is an open-label study in which a total of up to 20 participants will be enrolled in the study and will receive active treatment, applied to all HS lesions twice daily for 8-weeks.
