Summary
This was an open-label study to evaluate the safety and pharmacokinetics of tavaborole 5% topical solution in treating distal subungual onychomycosis (a fungal infection) of the toenail in children and adolescents (ages 6 to 16 years). Following confirmation of eligibility, including laboratory evidence of a fungal organism in the toenail, tavaborole topical solution was applied once daily to all affected toenails for a 48-week treatment period. Clinical assessment of the extent of infection and safety assessments were performed periodically throughout the 48-week treatment period, and again at 52 weeks (4 weeks after stopping the treatment). A subgroup of enrolled subjects applied the topical solution to all 10 toenails and a small area of surrounding skin during the first 28 days. These subjects had blood samples analyzed to evaluate the pharmacokinetics (how the drug moves in the body) of tavaborole topical solution in children and adolescents.
