Brief Title: Sequential Intensive Chemotherapy Followed by RIC for Refractory and Relapse AML

Official Title: Sequential Intensive Chemotherapy Followed by Allogeneic Stem Cell Transplantation With Reduce-intensity Conditioning for Refractory and Relapse Acute Myeloid Leukemia in Adult Patients

Study ID: NCT01496547

Interventions

intensive chemo - RIC preparation

Study Description

Brief Summary: Patients with refractory and relapse leukemia had poor outcome even with allogeneic stem cell transplantation. In our previous retrospective study, the overall survival is 14.6+/-8.8% while 90% patients eventually relapsed with marrow ablative conditioning mostly standard iv-Bu-Cy or Cy-TBI. The accumulated TRM is 29.5+/-11.5%. Thus our data suggested that the conventional transplantation approach may not be able to overcome the refractory disease. A new strategy to combined a low dose regimen following intensive chemotherapy for tumor reduction seems to be effect in both relapsed. high-risk and refractory AML or ALL. In this study, we focus on a new treatment strategy for particular refractory AML patients.

Detailed Description: This is a single arm phase II trial to test the efficacy and feasibility of new sequential intensive chemo and transplantation approach for refractory leukemia. Patients with refractory acute myeloid or lymphoblastic leukemia are enrolled in this trial. Patients will received intensive chemotherapy including Fludarabine, cytarabine and idarubicin as (FLAG-IDA). Seven days after the chemotherapy, sequential transplantation conditioning regimen as fludarabine and busulfan will be given.
