Keywords
Superficial Basal Cell Carcinoma, Aldara
Brief summary
An open-label study to evaluate the safety and the ability of Imiquimod 5% cream, applied topically, to clear superficial basal cell carcinoma and to keep it clear for 5 years of follow-up.
Detailed description
Evaluate the long-term sustained clearance rate, defined as the proportion of those subjects clinically clear of basal cell carcinoma (BCC) at the treated superficial BCC (sBCC) target tumor site at the 12-week posttreatment visit who remain clear during a 5 year follow-up period.
Interventions
Aldara (imiquimod) 5% cream - 250 mg / packet - once daily 7 days per week for 6 weeks

Outcome results
Number of Participants With Sustained Clearance Rate of Superficial Basal Cell Carcinoma (sBCC)
Number of participants clinically clear of superficial basal cell carcinoma at the treated target tumor site at the 12-week posttreatment visit (ie, initial clearance rate) who remain clear during a 5 year follow-up period.
Time frame: 5 years
Population: 2 data sets: ITT - all enrolled subjects and PP - ITT subjects free from major protocol violations and applied at least 60% of doses required
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Aldara | Number of Participants With Sustained Clearance Rate of Superficial Basal Cell Carcinoma (sBCC) | 119 participants |
Number of Participants Cleared of Superficial Basal Cell Carcinoma at 12 Weeks
Number of participants cleared at 12 weeks(the number of subjects with no clinical evidence of superficial basal cell carcinoma at the target tumor site at the 12-week posttreatment visit)
Time frame: 12 week posttreatment visit
Population: Two data sets were analyzed: intent-to-treat (ITT), consisting of all enrolled subjects and per-protocol (PP), consisting of ITT subjects who were free from major protocol violations, and who applied at least 60% of the doses required by the dosing regimen.
| Arm | Measure | Value (NUMBER) |
