Primary Endpoints
The Percentage of Participants Who Achieve Effective Treatment at Week 52
Week 52

At each study visit, the investigator assessed the percentage of affected toenail on the target nail by estimating the percent affected nail in each quadrant, summing the percent affected in each quadrant and dividing the sum by 4. Effective treatment was defined as a mycological cure and clear or almost clear nail (distal subungual hyperkeratosis and/or onycholysis leaving less than 10% of nail plate effected). Comparisons were carried out in a sequential step-down fashion, combined with the Holm procedure at step 2. P-value was based on a sequential step-down combined with the Holm procedure. It was assessed on Week 4, 8, 12, 16, 20, 24, 30, 36, 44 and 52.
