Phase 3 Study of Imiquimod Creams in the Treatment of External Genital Warts - Full Text View

Purpose

The purpose of this study is to determine whether imiquimod creams are effective in treating external genital warts (EGW). The secondary objective of this study is to provide information on recurrence of EGW. Additionally the study will also look at any adverse events associated with the use of the creams.

External genital and perianal warts are caused by the infection of human papillomavirus or HPV. HPV infection is a sexually transmitted disease (STD). External genital warts look like small flesh-colored, pink, or red growths on or around the external skin of sex organs or perianal area. The warts may look similar to the small parts of a cauliflower or they may be very tiny and difficult to see. They often appear in clusters of three or four, and may grow and spread rapidly. They usually are not painful, although they may cause mild pain, bleeding, and itching.

Primary Outcome Measures:

Proportion of Subjects Achieving Complete Clearance of All Warts (Baseline and New) at the End of Study. [ Time Frame: Up to 16 weeks ]
The complete clearance was defined as completely cleared all warts including baseline and newly emerged during the study at all anatomic areas.

Secondary Outcome Measures:

Number of Subjects With Any Treatment Related Adverse Reactions (AEs), Any Local Skin Reactions (LSRs), and Number of Subjects Who Took Rest Periods During the Treatment Period [ Time Frame: Up to 16 weeks ]
Treatment related defined as "probably related" or "related" by investigator. Local skin reactions (LSRs)were part of the treatment related adverse events and assessed by the investigators.

Rest periods defined as temporary interruption of dosing due to intolerable local skin reaction.
