Imiquimod Cream in Treating Patients With Basal Cell Skin Cancer
Double-Blind, Vehicle-Controlled Study to Evaluate Apoptosis in Basal Cell Carcinoma Treated With Aldara™ (Imiquimod) Cream, 5% Applied Once or Twice a Day
RATIONALE: Biological therapies, such as imiquimod cream, work in different ways to stimulate the immune system and stop tumor cells from growing.
PURPOSE: This randomized phase I trial is studying how well imiquimod cream works in treating patients with basal cell skin cancer.
연구 개요
상세 설명
OBJECTIVES:
Primary
- Compare levels of apoptosis in patients with basal cell skin cancer treated with vs without imiquimod 5% cream.
Secondary
- Compare levels of apoptosis in patients treated with this drug on two different administration schedules.
OUTLINE: This is a randomized, double-blind, placebo-controlled, parallel-group study.
Patients undergo fine needle aspiration and punch biopsies of the target lesion. Patients are then randomized to 1 of 8 treatment arms and begin therapy within 30 days after biopsy.
- Arm I: Patients apply topical imiquimod to the target lesion once every 12 hours on days 1 and 2 for a total of 4 doses.
- Arm II: Patients apply topical placebo to the target lesion once every 12 hours on days 1 and 2 for a total of 4 doses.
- Arm III: Patients apply topical imiquimod to the target lesion once every 24 hours on days 1-4 for a total of 4 doses.
- Arm IV: Patients apply topical placebo to the target lesion once every 24 hours on days 1-4 for a total of 4 doses.
- Arm V: Patients apply topical imiquimod to the target lesion once every 12 hours on days 1-4 for a total of 8 doses.
- Arm VI: Patients apply topical placebo to the target lesion once every 12 hours on days 1-4 for a total of 8 doses.
- Arm VII: Patients apply topical imiquimod to the target lesion once every 24 hours on days 1-8 for a total of 8 doses.
- Arm VIII: Patients apply topical placebo to the target lesion every 24 hours on days 1-8 for a total of 8 doses.
All patients undergo excision of the target tumor within 18-30 hours after the last topical treatment.
Patients are followed at 7-14 days.
PROJECTED ACCRUAL: A total of 48 patients (8 per treatment arm and 4 per placebo arm) will be accrued for this study.
