Outcome Measures
Primary Outcomes (1)
Percentage of Subjects With Complete Cure at Week 6.
The first primary efficacy variable was the percentage of subjects in the NAFT-500 Cream, 2% or 2-week placebo groups with complete cure at Week 6. The second primary efficacy variable was the percentage of subjects in the Naftin 1% Cream or 4-week placebo groups with complete cure at Week 6. Complete cure was defined as negative mycology results from the central laboratory (dermatophyte culture and KOH) and absence of erythema, scaling, and pruritus that were evaluated using a 4 point severity scale.
