Open-label Study to Evaluate the Use of Imiquimod 5% Cream for Reducing Postsurgical Recurrence or Persistence of Basal Cell Carcinoma Following Excision by Curettage
Open-label Study to Evaluate the Use of Imiquimod 5% Cream for Reducing Postsurgical Recurrence or Persistence of Basal Cell Carcinoma Following Excision by Curettage
The primary objective of this study is to assess whether basal cell carcinoma (BCC) lesions surgically treated with curettage, followed by imiquimod 5% cream as postsurgical adjuvant therapy, will have an improved cure rate over the ED/C historical norm of approximately 70% at 1-year posttreatment follow-up. A secondary objective is to assess cosmetic outcome.
This was an open-label, phase IIIb, multicenter, single arm, historical-controlled study. Biopsy-confirmed BCC lesions (1 per subject) were excised by curettage, with no electrodessication. Approximately 1 week later, treatment with imiquimod 5% cream was initiated. Imiquimod was applied to the target BCC once daily, 5 times per week (5x/week) for up to 6 weeks. Rest periods were allowed as needed. Subjects reported to the study center at treatment weeks 1, 2, and 6, and posttreatment at weeks 12, 26, and 52. At treatment week 6 and all posttreatment visits, the investigator clinically assessed the target site for tumor clearance and cosmetic outcome. A template made at initiation and created from clear plastic overlay aided in locating the target tumor site. If the investigator identified a lesion that had occurred or recurred at the target site, the subject was discontinued from the study and counted as a recurrence/persistence (R/P).
