Comparison Between Podofilox Topical Gel 0.5% and Allergan's Condylox® Gel 0.5% for External Anogenital Warts

This is a multicenter, parallel group, randomized, double-blind, placebo-controlled, trial with clinical endpoint comparing Podofilox Topical Gel 0.5% to Condylox® Gel 0.5% and a matching placebo. The study will be conducted among adult male and female patients with external anogenital warts. The Investigator will assess vital signs and perform physical examination identifying any clinically significant abnormalities. Laboratory samples will be collected, including HIV, Hepatitis B&C, and urine pregnancy tests (UPT) for women of childbearing potential. The Investigator will confirm the diagnosis of External Anogenital Warts (EAW) and the absence of contraindications specified in the exclusion criterion 4 during the visual examination. The biopsy of skin lesions will be performed per the discretion of the Investigator for microscopic verification of the diagnosis of EAWs if any doubts of the diagnosis.
