Abstract

OBJECTIVE:

To evaluate if new imiquimod formulations using a shorter treatment duration are safe and efficacious to treat anogenital warts.

METHODS:

In two studies 534 women ≥12 years of age (mean 33.4) with 2-30 warts (mean 7.9) and total wart area ≥10 mm(2) (mean 166.3) were randomized (1:2:2) to placebo (106), imiquimod 2.5% (212) or 3.75% (216) creams applied once daily until complete clearance or a maximum of 8 weeks.

RESULTS:

For placebo, imiquimod 2.5% and 3.75%, respectively, complete clearance of all warts was achieved in 14.2%, 28.3%, and 36.6% of women (intent-to-treat, P = 0.008 imiquimod 2.5%, and P < 0.001 3.75% versus placebo). Mean changes in wart counts were -10.7%, -50.9%, and -63.5% (per-protocol, P < 0.001 each active versus placebo) and safety-related discontinuation rates 0.9%, 1.4%, and 2.3%.

CONCLUSIONS:

Imiquimod 3.75% applied daily for up to 8 weeks was well tolerated and superior to placebo in treating women with external anogenital warts.
