Interventions
Study treatment: oral Arsenic 5d/7 for 21 days over a 28-day cycle, three doses tested (0.10 mg/kg, 0.15 mg/kg and 0.20 mg/kg). Dose escalation cohort to determine the dose limiting toxicity according to a BOIN (Bayesian optimal interval) scheme, 9 patients will be treated at each dose. An expansion cohort at the selected dose will be conducted with 6 patients. Tolerability will be assessed after one treatment cycle. Response will be assessed after 3 cycles of treatment. Responders may continue study treatment until progression or limiting toxicity. Limiting toxicity is defined as any grade III/IV extra-hematological toxicity or grade IV hematological toxicity lasting more than 25 days.
