Clinical Evaluation of the Efficacy of a Medical Device in Treatment of Toenail Onychomycosis

Study Overview
=================
Brief Summary
-----------------
This study evaluates the effect of the medical device Excilor® Fungal Nail Infection in the treatment of toenail onychomycosis. Half of the participants will receive the tested product and the other half will receive a comparator (Amorolfin 5%). Patients will be followed during 6 months.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| At the end of the study (day 168), evolution of the percentage of healthy surface versus baseline, was evaluated by a blinded investigator. Comparison with the comparator product. | Percentage healthy surface was assessed using digital image analysis. Briefly, two macro-photographs (top and front) were made of the great toenail, placed beside a piece of graph paper to allow determination of the exact size of the nail during analysis (contour tracing). Consequently, all pictures were digitalised and recorded on the computer. Image analysis of the top picture was performed with Adobe Photoshop software. For each photograph, a blinded dermatologist traced the healthy surface. | After 168 days of treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| At different time points, evolution of the percentage of healthy surface versus baseline, was evaluated by a blinded investigator. Comparison with the comparator product. | Percentage healthy surface was assessed using digital image analysis. Briefly, two macro-photographs (top and front) were made of the great toenail, placed beside a piece of graph paper to allow determination of the exact size of the nail during analysis (contour tracing). Consequently, all pictures were digitalised and recorded on the computer. Image analysis of the top picture was performed with Adobe Photoshop software. For each photograph, a blinded dermatologist traced the healthy surface. | After 14, 28, 56 and 112 days of treatment | 
| Evaluation of the clinical efficacy assessed by the investigator with structured scales. Comparison with the comparator product. | Onycholysis, nail dystrophy, nail discoloration and nail thickening were assessed using the following scores: 0 = none, 1 = very slight, 2 = slight, 3 =moderate, and 4 = severe. | On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168 | 
| Evaluation of the microbiological efficacy of the product assessed by fungal culture and comparison with the comparator product. |  | On baseline (day zero) and day 168 | 
| Evaluation of the product tolerance, assessed by the investigator by clinical evaluation and subject interrogatory with a score from 0 (bad tolerance) to 3 (very good tolerance). |  | After 14, 28, 56 and 112 days of treatment | 
| Evaluation of the quality of life of the subjects thanks to the questionnaire NailQoL . Comparison with the comparator product. |  | On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168 | 
| Subjective evaluation by subjects by completing the subjective evaluation questionnaire at each visit. |  | On Day 0, Day 14, Day 28, Day 56, Day 112 and Day 168 |
