Efficacy and Safety of Efinaconazole 10% Solution in the Treatment of Onychomycosis in Diabetic Patients

Study Overview
=================
Brief Summary
-----------------
Onychomycosis, a common pathology of the toenails, is even more prevalent among diabetic subjects. Nearly 26 million Americans suffer from diabetes, and approximately one-third of subjects with diabetes have toenail onychomycosis. Numerous studies have addressed the efficacy and safety of both topical and oral antifungal treatment options for onychomycosis in diabetic subjects. However, no study to date has specifically addressed the efficacy and safety of efinaconazole among diabetic subjects. The objective of this noncomparative, uncontrolled study is to determine the efficacy of topical efinaconazole 10% for toenail onychomycosis among subjects with diabetes mellitus. Specific indicators to measure efficacy of treatment will be the mycological cure rate, complete cure rate, and treatment success. Furthermore, an additional goal of the study is to gain knowledge of safety in the setting of a cohort of diabetic subjects

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Primary Endpoint - Efficacy | The primary efficacy end point is the proportion of subjects achieving complete cure at week 50. Complete cure is to be defined as a combination of 0% clinical involvement and mycological cure (mycological cure defined as negative KOH examination and negative fungal culture of the target toenail sample). | 50 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Secondary Endpoint - Efficacy | The first secondary efficacy end point is mycological cure, defined as negative KOH examination and negative fungal culture of the target toenail sample. | 50 weeks | 
| Secondary Endpoint - Efficacy | The second secondary efficacy end point is clinical cure, defined as 0% clinical involvement of the target toenail. | 50 weeks | 
| Secondary Endpoint - Safety (Occurrence of Adverse Events: Type and Frequency) | The secondary safety endpoint is the occurrence of adverse events (type and frequency). | 50 weeks |
