Planimetric Post-hoc Analysis of Women With Onychomycosis from Tavaborole 5% Phase III Studies: Evidence of Greater Improvements in Patients With >50% Baseline Infection.

Overview

Women with onychomycosis may suffer more effects on their quality of life than men. There is limited female-specific data on the treatment of onychomycosis. Tavaborole is a topical treatment option for onychomycosis. This post-hoc study evaluated the nail plates of women using data from the tavaborole 5% Phase III studies at baseline and end of study for the areas of healthy nail and infected nail. Over 52 weeks (48-week treatment, 4-week follow up), women treated with tavaborole had an average 32% increase in healthy nail and 21% decrease in infected nail. Patients with baseline infection involving >50% of the nail plate had an average increase in percentage of unaffected nail surface area of 81% and a corresponding 51% decrease in infected nail. These analyses suggest that patients with the greatest toenail involvement at baseline had greater overall improvements than those who were less affected. This evaluation provides additional clinical guidance for treating women with onychomycosis using tavaborole. J Drugs Dermatol. 2018;17(2):168-172.
