Brief Summary: Results from a pilot study demonstrated that topical imiquimod could clear superficial and nodular BCCs Three phase II dose response studies in subjects with nodular BCC nBCC showed that the histological cure rates with imiquimod depend on the doses applied per week and the duration of treatment Daily dosing or 5 times per week applications showed higher total clearance rates than 3 times per week dosing or less frequent dosing Furthermore a 12 week treatment period resulted in better efficacy results than a duration of only 6 weeks On the other hand local skin reactions increased with the doses applied per week So a prolonged treatment period of 8 or 12 weeks with an application frequence of 3 times a week seems to be a good compromise between efficacy and safety
Detailed Description: Basal cell carcinoma BCC is a malignant skin cancer that is believed to develop from the basal layer of the epidermis Ultraviolet UV radiation is the primary cause of BCC It induces local and systemic immuno-suppression p53 mutations pyrimidine covalent dimers in desoxyribonucleic acid DNA and bcl-2 overexpression All of these UV-induced changes are believed to be critical in the pathogenesis of BCC

Topical application of imiquimod induces local interferon-alpha IFN-alpha interleukin-12 IL-12 and tumor necrosis factor-alpha TNF-alpha with a resulting cytokine cascade that may induce andor support a cytotoxic T-lymphocyte Th1 immune response Intralesional IFN-alpha has been shown to be effective for the treatment of BCC Imiquimod may be an effective therapy for BCC

The current safety and efficacy study of imiquimod 5 cream in the treatment of nodular basal cell carcinoma nBCC will use a composite endpoint including both a clinical visual assessment of the target tumor site and a histological evaluation of an excisional surgery taken from the target tumor site for primary assessment of complete tumor clearance 8 weeks post treatment
