NCT02267356

Brief Summary

Several properties of VT-1161 suggest that it might be a safer and more effective treatment for onychomycosis of the toenail (also known as toenail fungus) than other oral antifungal medicines. This study will evaluate the effectiveness and safety of VT-1161 for the treatment of toenail onychomycosis and consists of a screening phase, a 24-week treatment phase in which the patient will take either active drug, placebo or a combination of the 2 (according to random assignment), an initial observational phase of 36 weeks and an additional observational study extension of 9 months. The additional 9-month observational study extension was added with a protocol amendment and patient participation was optional.

Outcome Measures

Primary Outcomes (2)

  • The Proportion of Subjects in the Intent-to-treat Population With Complete Cure, Defined as Clinical AND Mycological Cure, at Week 48

    Complete cure was defined as 0% nail involvement and an Investigator Global Assessment (IGA) score of 0. Mycological cure was defined as negative potassium hydroxide (KOH) and negative dermatophyte culture. Investigator Global Assessment (IGA) scoring: 0: 0% nail involvement 1. \>0% to ≤10% nail involvement 2. \>10% to \<25% nail involvement 3. ≥25% to ≤50% nail involvement 4. \>50% to ≤75% nail involvement 5. \>75% nail involvement
