Clinical Trial Summary

This clinical trial seeks to investigate if an experimental medical device, ABL01, can be used to treat onychomycosis. In a 1-year trial the effectiveness of ABL01 will be tested against placebo in 70 study subjects with onychomycosis of the big toe nail. The endpoint of the trial is clinical improvement and cure at the 6 and 12 month time-point.

Description:

The purpose of this clinical trial is to determine the safety and effectiveness of the medical device ABL01. The intended use of ABL01 is to reduce and treat onychomycosis, fungal nail infection. ABL01 is a solution intended to be topically administered weekly to infected nails. The trial is designed as a double blinded randomized placebo controlled clinical trial. The trial involves 70 study subjects, half of which will receive ABL01 and the other half placebo. The inclusion criteria for study subjects are adult men and women that present with distal lateral subungual onychomycosis (DSU) on the big toe nails. Furthermore, the extent of DSU should not involve more than half of the area of the nail.

The study subjects will themselves apply the study solution weekly to the treated nail. The trial will run for 6 months with a possible extension to maximum 12 months. There will be a total of 4 study visits at baseline, 3, 6 and 12 months to follow up the progress of the trial. The primary objective of the trial is to determine if ABL01 treatment are able to reduce and treat onychomycosis. Secondary objectives are to collect safety data, determine if the ABL01 are perceived as easy to use and assess long term effects of the treatment. The endpoint of the trial is reduction in clinical signs or complete cure of onychomycosis at the 6- or 12-month time-point.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of study subjects with a reduction in infected nail area at 6 months.	Clinical improvement of the condition is assessed by analyzing changes in infected nail area (in relation to total nail area) due to ABL01 or placebo treatment. Clinical improvement is considered to be a 40% reduction in infected area at the 6 month time period.	6 months
Secondary	Questionnaire regarding subjects opinion of the treatment, nail improvement.	Subjects score (1-5) the perceived improvement of their nail condition.	12 months
Secondary	Questionnaire regarding subjects opinion of the treatment, ease of use.	Subjects score (1-5) the perceived ease of using ABL01.	12 months
Secondary	Number of study subjects with treatment-related adverse events	Subject reported safety data in combination with reported adverse events and adverse device effects related to the topical administration of ABL01.	12 months
Secondary	Number of study subjects with a reduction in infected area of the nail	Clinical improvement of the condition is assessed by analyzing changes in infected nail area (in relation to total nail area) due to ABL01 or placebo treatment. Clinical improvement is considered to be a 80% reduction in infected area at the 12 month time period.	12 months
Secondary	Number of study subjects with clinical cure	Clinical cure is established with a negative test for dermatophytes as assessed by DNA-analysis.	12 months
