Side Effects Overview

6 ADVERSE REACTIONS During clinical trials with Ecoza topical foam, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the Ecoza and vehicle arms. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Resilia Pharmaceuticals at 1-888-998-0770 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In two double-blind, vehicle-controlled clinical trials, 495 subjects were exposed to Ecoza topical foam or vehicle (246 subjects were exposed to Ecoza topical foam, 1% and 249 were exposed to vehicle). Subjects with interdigital tinea pedis applied foam or vehicle once daily for approximately 28 days. During clinical trials with Ecoza topical foam, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the Ecoza and vehicle arms.

12.3 Pharmacokinetics The systemic absorption of Ecoza topical foam, 1% following topical application was studied in one clinical trial in adults and one clinical study in pediatric subjects. In the adult trial, 19 subjects (male and female) with tinea pedis applied Ecoza topical foam, 1% once daily for 29 days. Subjects applied a mean daily amount of 2.4 g of Ecoza topical foam, 1% to soles, toes, interdigital spaces and tops of both feet up to the ankles. Blood samples were obtained on Day 29 at pre-dose and 1, 2, 4, 6, 8, and 12 hours after application. Results (mean ± SD) showed the time to reach peak plasma concentrations (T max ) was 6.8 ± 5.1 h with maximum concentration (C max ) of 417 ± 218 pg/ml. The area under the concentration time curve for the first 12 hours post application on Day 29 (AUC (0-12) ) was 3440 ± 1920 pg-h/ml. In the pediatric trial, 18 subjects (male and female ages 12 - 17) with interdigital tinea pedis and positive fungal cultures were treated with Ecoza topical foam, 1% once daily for 4 weeks. Subjects applied a mean daily amount of 3.2 g of Ecoza topical foam, 1% to soles, toes, interdigital spaces and tops of both feet up to the ankles. Blood samples were obtained on Day 28 at pre-dose and 7 h and 11 h post-dose. The mean ± SD econazole plasma concentration was 397 ± 289, 534 ± 745 and 575 ± 638 pg/mL at pre-dose and 7 h and 11 h post-dose, respectively.
