Deferasirox in Treating Patients With Iron Overload After Undergoing a Donor Stem Cell Transplant
Study Details
Study Description
Brief Summary
RATIONALE: Deferasirox may be effective in treating iron overload caused by blood transfusions in patients who have undergone donor stem cell transplant.
PURPOSE: This phase II trial is studying the side effects and how well deferasirox works in treating patients with iron overload after donor stem cell transplant.

Phase 2 |
Detailed Description
OBJECTIVES:
Primary
- To evaluate the safety of deferasirox given over 6 months in reducing liver iron concentration in patients with transfusional iron overload after undergoing allogeneic hematopoietic stem cell transplantation.
Secondary
- To evaluate the efficacy of deferasirox in reducing liver iron overload in these patients.
OUTLINE: This is a multicenter study.
Patients receive oral deferasirox once daily for 6 months in the absence of disease progression or unacceptable toxicity.
After completion of study therapy, patients are followed at 4 weeks.

Outcome Measures
Primary Outcome Measures
- Number of Patients Not Completing Treatment [6 Months]
Number of patients who discontinued deferasirox during 6 month daily treatment due to drug related toxicity
Secondary Outcome Measures
- Reduction in Liver Iron Concentration After Study Drug [6 Months]
Efficacy as measured by reduction in liver iron concentration (LIC) after 6 months of the study drug compared to baseline (LIC at baseline minus LIC at 6 months). This shows the mean reduction for the 3 subjects treated in this study.
Eligibility Criteria
Criteria
Inclusion Criteria:

-
Refused phlebotomy
-
ECOG performance status of 0-2

-
Must be able to give written informed consent.
-
Prior therapy with deferoxamine allowed provided it was completed ≥ 12 months ago
Exclusion Criteria:
