Arsenic Trioxide in Treating Patients With Refractory or Recurrent Acute Promyelocytic Leukemia

Phase 1

Completed

• Conditions: Leukemia
• Interventions: Drug: arsenic trioxide

• Registration Number: NCT00008697
• Lead Sponsor: Washington University School of Medicine

Brief Summary

The purpose of this study is to evaluate both the efficacy and toxicity of infusional arsenic trioxide in the treatment of patients with relapsed or refractory acute promyelocytic leukemia (APML). In addition, correlation between pharmacokinetic data and both therapeutic response and therapy-related toxicities will be sought.

Detailed Description

OUTLINE: This is a dose-escalation study.

Patients receive arsenic trioxide IV over 2 hours daily for 28 days followed by a 14 day rest period. Patients may receive up to 3 courses of treatment.

Arm && Interventions

Group	Intervention	Description
Phase 1	arsenic trioxide	Cohort 1 Arsenic trioxide = 0.1 mg/kg/day x 28 days with 14 day rest for 3 cycles (each cycle = 6 weeks) Cohort 2 Arsenic trioxide = 0.15 mg/kg/day x 28 days with 14 day rest for 3 cycles (each cycle = 6 weeks) Cohort 3 Arsenic trioxide = 0.20 mg/kg/day x 28 days with 14 day rest for 3 cycles (each cycle = 6 weeks) Cohort 4 Arsenic trioxide = 0.25 mg/kg/day x 28 days with 14 day rest for 3 cycles (each cycle = 6 weeks) Cohort 5 Arsenic trioxide = 0.30 mg/kg/day x 28 days with 14 day rest for 3 cycles (each cycle = 6 weeks)
Phase 2	arsenic trioxide	Arsenic trioxide = MTD found in Phase 1 mg/kg/day x 28 days with 14 day rest for 3 cycles (each cycle = 6 weeks)
