Phase 2

Completed

• Conditions: Onychomycosis

• Registration Number: NCT00679601
• Lead Sponsor: Pfizer

Brief Summary

The purpose of the study is to determine the absorption and systemic pharmacokinetics of AN2690 following daily application to all ten (10) toenails for 28 days.

Detailed Description

A single center, open-label, multiple-dose study design will be used. Planned enrollment is 20 subjects to complete 15. Subjects must have a clinical diagnosis of onychomycosis of each great toenail and a clinical diagnosis of onychomycosis of six of the remaining toenails.
