Arsenic Trioxide in Treating Patients With Basal Cell Carcinoma

An Open-label, Biomarker Study of Arsenic Trioxide for the Treatment of Patients With Basal Cell Carcinoma

This pilot clinical trial studies arsenic trioxide in treating patients with basal cell carcinoma. Drugs used in chemotherapy, such as arsenic trioxide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stop them from dividing

PRIMARY OBJECTIVES:

I. To determine whether administration of arsenic trioxide (ATO) to patients with basal cell carcinoma is associated with a reduction in Gli messenger ribonucleic acid (mRNA) and protein levels in tumor biopsy samples, when compared to baseline levels.

SECONDARY OBJECTIVES:

I. To determine whether there is evidence of tumor size reduction of ATO against basal cell carcinoma in humans.

OUTLINE:

Patients receive arsenic trioxide intravenously (IV) over 2 hours on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

INCLUSION CRITERIA

• Basal cell carcinoma (BCC)
• Ineligible for curative locoregional treatment and have either progressed on, did not tolerate, unwilling to try or ineligible for investigational smoothened antagonist such as vismodegib (GDC 0449), XL 139 (BMS 833923), IPI- 926, LDE225 and PF-04449913
• Life expectancy estimate > 3 months
• Performance status Eastern Cooperative Oncology Group (ECOG) 0-2
• Absolute neutrophil count ≥ 1,500/mcL
• Platelets ≥ 100,000/mcL
