Combination of Decitabine and Temozolomide in the Treatment of Patients With Metastatic Melanoma

"In Part I patients will be treated on a standard 3+3 phase I dose-escalation design starting at 0.075 mg/kg until a decitabine dose level of 0.15 mg/kg is reached, or, in case unacceptable toxicities are observed, at the maximum tolerated dose (Phase II recommended dose). Decitabine will be administered at the specified dose level, intravenously, daily 5 days a week for the first 2 weeks of a 6-week cycle."

Temozolomide is available in 25 mg and 100 mg tablets that will be administered orally; doses will be rounded to the nearest 25 mg. Temozolomide will be administered orally at 75 mg/m2 daily for 4 weeks starting on week 2 of a 6-week cycle.

Fine needle aspirates (FNA) and/or core biopsies of tumor samples will be obtained from consenting patients with accessible, evaluable disease, on days 1, 8, 15, and 29 of the first cycle and when patients go off study. Biopsies are optional in Phase I and required for all consenting subjects in Phase II.
