  • Patent number: 11318130
    Abstract: Pharmaceutical formulations and methods for the topical or transdermal delivery of 1-isobutyl-1H-imidazo[4,5-c]-quinolin-4-amine or 1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-4-amine, i.e., imiquimod, to treat actinic keratosis with short durations of therapy, than currently prescribed for the commercially available Aldara® 5% imiquimod cream, as now approved by the U.S. Food & Drug Administration (“FDA”), are disclosed and described. More specifically, lower dosage strength imiquimod formulations to deliver an efficacious dose of imiquimod for treating actinic keratosis with an acceptable safety profile and dosing regimens that are short and more convenient for patient use than the dosing regimen currently approved by the U.S. Food & Drug Administration (“FDA”) for Aldara® 5% imiquimod cream to treat actinic keratosis are also disclosed and described.

  • Publication number: 20110319811
    Abstract: The present invention is directed to the use of complementary or combination lesion-directed therapy, such as cryosurgery, and field-directed therapy, such as low dose imiquimod topical therapy with short durations, in combination to treat actinic keratosis (“AK”). In carrying out the present invention, the lesion-directed and field-directed therapies may be applied sequentially or concomitantly, in accordance with the present invention. The novel complementary or combination AK therapy contemplated by the present invention: (1) significantly improves clearance of cryosurgery-treated Aks; (2) treats subclinical AK lesions; (3) treats those visible AK lesions in excess of that cryosurgery can actually treat in a single treatment due to, e.g., patient tolerance, provider treatment limits and/or cryosurgery cost to the patient; and (4) enhances sustained clearance overall, as compared to mono AK lesion-directed therapy.
