An Open-label Study Evaluating the Effectiveness of CGB-400 Topical Gel for Fungal Infection

• Conditions: Fungal Infection; Onychomycosis; Tinea Unguium
• Interventions: Drug: CGB-400 Topical Gel

• Registration Number: NCT05202366
• Lead Sponsor: CAGE Bio Inc.

Brief Summary

The goal of the current study is to evaluate the ability of CGB-400, a proprietary eutectic mixture of GRAS compounds, to clear the toenail fungal growth and improve the appearance of the fungus affected area(s).

This is an open-label, single group POC study evaluating the effectiveness of CGB-400 Topical Gel for toenail fungal growth clearing. The study consists of a 12-week period with 5 clinic visits at the following timepoints: Baseline (Day 0), and Weeks 2, 6, and 12 and post-application follow-up at Week 24. The applications could be extended for an additional 12 weeks based on PI's observations.

Approximately 15 subjects will be enrolled and subjected to application of CGB-400 Topical Gel. Subjects must be at least 18 years of age and will be selected by the concerned PI.
