Detailed Description:
To compare the recurrence rate 24 weeks after ablative therapy in subjects with external genital warts trated with imiquimod, 3 applications per week for 4 weeks followed by ablative therapy versus vehicle, 3 applications per week for 4 weeks followed by ablative therapy. A recurrence is defined as the investoigator-assessed occurrence of lesion(s) within the baseline area cleared by the treatment: imiquimod/vehicle then ablative therapy (either the initial ablative therápy session (A0), or if required for complete clearance of baseline lesions, a second ablative therapy session (A2).
