Detailed Description:
A phase 2, randomized, double-blind, placebo-controlled, parallel-group, dose-ranging study to investigate the efficacy and safety of 4 dose regimens of ORAL albaconazole in subjects with distal subungual onychomycosis. Subjects will take oral study drug for up to 36 weeks and then will be followed for an additional 16 weeks to determine if the study drug was efficacious. Subjects will have routine blood draws and other safety assessments during the study, as well as regular assessments of their toenail fungus

  • Subject is willing to provide signed and dated written voluntary informed consent (and any local or national authorization requirements) before any protocol-specific procedures are performed.
  • Subject is able to complete the study, comply with study instructions, and take study product orally.

  • Subject has participated in a clinical trial for the systemic treatment of onychomycosis of the toenails within 6 months prior to the first dose of study product.
  • Subject is receiving any drugs that are known substrates of the 3A4 isozyme of cytochrome P450 (CYP3A4) with QT prolongation potential or any of the concomitant medications listed under prohibited medication section.
