Aldara(TM) (Imiquimod) Cream, 5% Included in More Than 20 Presentations at American Academy of Dermatology's 64th Annual Meeting.

ST. PAUL, Minn. -- 3M (NYSE:MMM):

--Aldara is the First and Only Immune Response Modifier Indicated for the Treatment of Actinic Keratosis, Superficial Basal Cell Carcinoma and External Genital Warts

3M announced today that Aldara Cream is a featured topic in more than 20 presentations by leading researchers at the upcoming American Academy of Dermatology's (AAD) 64th annual meeting in San Francisco, March 3-7. Aldara Cream is the first and only immune response modifier indicated for the treatment of precancerous actinic keratosis, superficial basal cell carcinoma and external genital and perianal warts. The prescription therapy works by stimulating the skin's immune response to clear diseased or damaged cells.

"Dermatologists have come to recognize Aldara Cream as an important innovation in the treatment of actinic keratosis, external genital warts and basal cell carcinoma," said John Sampson, vice president, 3M Pharmaceuticals Division. "Aldara Cream's strong presence at the AAD annual meeting highlights dermatologists' recognition of the drug's unique mechanism of action, which engages the body's own immune system to fight these major skin conditions."

Aldara posters can be viewed in San Francisco's Moscone Center Hall A on:

--  Friday, March 3 (1 p.m. to 7 p.m.)

--  Saturday, March 4 and Sunday, March 5 (7 a.m. to 7 p.m.)

--  Monday, March 6 (7 a.m. to 5:30 p.m.)

Presenters will be at their posters from 12 p.m. to 2 p.m. on Saturday (even numbered posters) and Sunday (odd numbered posters). In addition to the poster presentations noted below, Aldara Cream also will be discussed during several ticketed symposia at the AAD annual meeting.

About Aldara Cream

Aldara Cream is a topical (skin-use only) prescription medicine and is the first and only immune response modifier (IRM) approved to treat three skin conditions: actinic keratosis, a precancerous skin condition, superficial basal cell carcinoma, a form of skin cancer, and external genital and perianal warts, caused by the Human Papillomavirus, or HPV. Aldara stimulates the body's own defense mechanism to identify and clear diseased and damaged cells. When using Aldara Cream, the most common side effects involved skin reactions in the application area. These included redness, swelling, erosions, induration, weeping, scabbing/crusting, flaking/scaling, itching and burning. Exposure to sunlight (including sunlamps) should be avoided or minimized during use of Aldara Cream for actinic keratosis or superficial basal cell carcinoma because of concern for heightened sunburn susceptibility. Patients should be warned to use protective clothing (hat) when using Aldara Cream.
