Trial Outcomes & Findings for A Trial to Evaluate the Safety and and Tolerability of DBI-001 in Patients With Tinea Pedis (NCT NCT04152226)

NCT ID: NCT04152226

Last Updated: 2025-06-17

Results Overview

Tolerability will be evaluated through assessment of local signs and symptoms. For simplicity, as there were no local tolerability reactions, the cumulative tolerability, inclusive of Pruritus, Erythema, Edema, Scabbing/crusting, and Burning/Stinging is represented in the table. Scoring for of each Pruritus, Erythema, Edema, Scabbing/crusting, and Burning/Stinging according to the scoring system below. Tolerability events were only considered adverse events if they were grade 3 or higher or required discontinuation of test article or use of conmeds. As no Tolerability events satisfied this criteria, there were no tolerability associated adverse events. 0 = none (complete absence) 1. = mild (slight) 2. = moderate (definitely present) 3. = Severe
