Spots Global Cancer Trial Database for Topical Laser-assisted Combination Chemotherapy for Basal Cell Carcinoma- a Clinical Study

Study Description

Brief Summary: A prospective clinical, uncontrolled, open-label, explorative phase IIa trial on patients with histologically- confirmed superficial and nodular basal cell carcinoma (BCC) . The study assesses tolerability and tumor clearance after laser-assisted topical delivery of two synergistic chemotherapeutic agents, cisplatin and 5-fluorouracil (5-FU) in BCC patients.

Detailed Description: Patients will receive ablative fractional laser (AFL)-assisted cisplatin+5-fluorouracil (5-FU) as a treatment for their cutaneous basal cell carcinoma (BCC). In brief, treatment areas consisting of tumors and a 5 mm margin will undergo AFL exposure (CO2 laser) followed by 60 min topical application of a marketed and commercially available IV cisplatin solution (0.1%) at a dose of 0.25 ml per cm2. After removal of cisplatin, a commercially distributed 5-FU cream (5% Efudix®) will be applied to the treatment area at a dose of 0.125 ml per cm2 and left under occlusion. After skin evaluations on Day 1 and 5 after treatment, the same 5-FU dose will be applied, again left under occlusion. In total, 5-FU will remain on the skin for 7 days after AFL treatment whereafter it will be washed off. An additional repeat AFL-cisplatin+5-FU treatment on Day 30 will be offered if tumors persist, based on clinical evaluation and imaging on Day 30. Outcome measures and methods/techniques are summarized below. Primary outcome: To investigate tolerability of topical AFL-assisted cisplatin+5-FU therapy for BCC by evaluating: I. Severity and duration of clinical local skin reactions including erythema, edema, scabbing, flaking and pustulation assessed by a physician using an established 0-4 point scale (none, mild, moderate, severe) from 0-30 days post-treatment. II. Occurrence of side effects (prolonged erythema/edema, hyper/hypopigmentation, scarring and infection) up to 3 months post-treatment. Secondary outcome: 1) To monitor BCC tumor size and clearance based on clinical assessments and dermoscopy, supported by non-invasive imaging techniques including dynamic optical coherence tomography (D-OCT), reflectance confocal microscopy (RCM), high intensity focused ultrasound (HIFU) and histological analysis up to 3 months post-treatment.
