A Study to Evaluate the Efficacy and Safety of Oral VT-1161 in Patients With Onychomycosis of the Toenail

• Status: Completed
• Trial end date: 2017-07-07
• Target enrollment: 0
• Participant gender: All

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
