The purpose of this study is to compare the recurrence rate following total clearance of external genital warts (EGWs) when clearance has been obtained by imiquimod (3 applications per week for 4 weeks) followed by ablative therapy (laser or electrocautery therapy) with that from just ablative therapy treatment alone.

Study Design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Safety/Efficacy Study

Study Primary Completion Date: December 2007

Detailed Clinical Trial 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).
