Study information
Scientific title
An open phase II study to assess the efficacy and safety of topical SR-T100® gel in the treatment of human cutaneous squamous cell carcinoma in situ (actinic keratosis and Bowen's disease)
Acronym
Study hypothesis
In our preliminary animal study to evaluate the efficacy and toxicity of topical SR-T100® gel, using an approved protocol of ultraviolet B (UVB)-induced hairless mouse (HRS) cutaneous cell carcinoma, 35 of 40 squamous cell carcinomas (SCCs) disappeared within 10 weeks of treatment (once-daily). Besides the high complete response rate (87.5%) as compared with the conventional therapy, the most significant result was that no undesirable side effects were associated with the use of SR-T100® gel.
We hypothesise that SR-T100® gel can be a potential alternative treatment for cutaneous squamous cell carcinoma in situ (actinic keratosis and Bowen's disease).
Ethics approval
Human Experiment and Ethics Committee of National Cheng Kung University Hospital approved on the 20th July 2007 (ref: HR-94-72).

Condition
Human cutaneous squamous cell carcinoma in situ (actinic keratosis and Bowens disease)
Intervention
Only one lesion will be selected for treatment and assessment in each patient. SR-T100® gel will be applied once daily on the targeted lesion and covered with an occlusive dressing. Patients will be instructed to apply the study gel to the entire area of target lesion including its peripheral normal skin approximately 1 cm around the tumour. Treatment will be continued until tumour is clinically cleared or until 16 weeks of treatment completed. The 16 week treatment is chosen on the basis of maximum duration treatment of topical drug on actinic keratosis and Bowen's disease previously reported.

SR-T100® gel
Primary outcome measure
To assess the response rate of SR-T100® in patients with cutaneous squamous cell carcinoma in situ (actinic keratosis and Bowen's disease), defined as the proportion of patients whose lesion size (length x width x height) is reduced greater than 75%. Measured until tumour is clinically cleared or until 16 weeks of treatment completed.
Secondary outcome measures
1. Complete clearance rate, defined as the proportion of patients with no clinically visible actinic keratosis and Bowen's disease lesions in the treatment area
2. Partial clearance rate, defined as the proportion of patients with at least a 75% reduction of actinic keratosis and Bowen's disease lesion size (length x width x height) in the treatment area
3. Histological response rate: proportion of patients with biopsy proven clearance of cutaneous squamous cell carcinoma in situ (actinic keratosis and Bowen's disease)
4. The safety profile of SR-T100® gel
Measured until tumour is clinically cleared or until 16 weeks of treatment completed.
