ECOZA (Page 2 of 3)

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies to determine the carcinogenic potential of Ecoza topical foam have not been performed.

Oral administration of econazole nitrate in rats has been reported to produce prolonged gestation.


In two multi-center, randomized, double-blind, vehicle-controlled clinical trials a total of 505 subjects with interdigital tinea pedis were randomized 1:1 to Ecoza topical foam or vehicle; subjects applied the assigned medication once daily for 4 weeks. The severity of erythema, scaling, fissuring, maceration, vesiculation, and pruritus were graded using a 4-point scale (none, mild, moderate, severe). Subjects had KOH examination and fungal cultures taken to confirm eligibility. A total of 339 subjects with positive fungal cultures were evaluated for efficacy. Efficacy was evaluated on Day 43, 2 weeks post-treatment with treatment success being defined as complete cure (negative KOH and fungal culture and no evidence of clinical disease). The study population ranged in age from 12 to 71 years with 5 subjects less than 18 years of age at baseline. The subjects were 71% male and 51% Caucasian. Table 1 presents the efficacy results for each trial.
