Study to Evaluate the Efficacy and Safety of P-3058 Nail Solution in the Treatment of Onychomycosis
- Conditions
- Onychomycosis of Toenail
- Interventions
- Drug: P-3058 (terbinafine hydrochloride 10%)Drug: Vehicle of P-3058
- Registration Number
- NCT03094468
- Lead Sponsor
- Polichem S.A.
- Brief Summary
The aim of this phase III study is to establish the efficacy and safety of P-3058 (terbinafine 10% nail solution) topically administered once weekly in patients with onychomycosis in comparison to the Vehicle in a double-blind fashion. The overall treatment period will be of 48 weeks.
- Detailed Description
The study will consist of a screening phase, a treatment phase of 48 weeks and a 12-week follow-up. Patients affected by mild to-moderate distal lateral subungual onychomycosis (DLSO) on a target great toenail will be included in the study. Clinical as well as mycology assessments will be performed throughout the whole study. Safety will be monitored by recording any adverse event and evaluating local tolerability.
