Fludarabine, Cytarabine, Topotecan in Treating Patients With Relapsed or Refractory Acute Myeloid Leukemia

• Status: Completed
• Trial end date: 2007-04-01
• Target enrollment: 0
• Participant gender: All

Summary

The study is designed with drugs used frequently in the treatment of AML, but with a new combination less toxic,and effective in AML multidrug resistant.

Justification:

• The AML patients with primary resistance or relapsed in the first 12 months after CR, have second line chemotherapy low response rate .

• These patients with AML with primary resistance or relapse, that reach remission after a rescue treatment, have an interval free survival and a global survival very short

• Probably the resistance to the treatments is in relation to different forms expression of the MDR.

• Complete remission is considered valid evaluation, because every patient who should obtain a CR can be considered to be eligible for a possible curative treatment: Ara-C administration to high doses or the TPH treatment

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: PETHEMA Foundation
• Treatments: Cytarabine; Fludarabine; Fludarabine phosphate; Topotecan; Vidarabine
