Brief Summary:
The purpose of this trial is to examine the safety and efficacy of deferasirox in patients with Myelodysplastic Syndrome (MDS) and chronic iron overload from blood transfusions.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Myelodysplastic Syndrome Iron Overload | Drug: Deferasirox | Phase 2 |
Study entry requires a diagnosis of low or intermediate (INT-1) risk MDS per International Prognostic Scoring System (IPSS) criteria and serum ferritin ≥ 1000 ng/mL. Patients must have had at least 30 prior red blood cell transfusions. Deferasirox will be administered at an initial dose of 20 mg/kg orally once per day. Patient transfusion history and at least three complete blood count (CBC) values must be available for the 12 weeks prior to study registration for patients with MDS and chronic iron overload from blood transfusions.

Primary Outcome Measures :
- 12 month safety in patients with myelodysplastic syndrome (MDS) [ Time Frame: throughout the study ]
Secondary Outcome Measures :
- Changes in serum ferritin from baseline to 3, 6, 9 and 12 months after initiating treatment [ Time Frame: throughout the study ]
- Effect of non-transferrin bound iron (NTBI), serum iron, transferrin and transferrin saturation on the safe administration of deferasirox [ Time Frame: throughout the study ]
- Changes in transfusion requirements, serum erythropoietin levels, and estimated frequency of hematologic improvement in patients who are not receiving growth factors or chemotherapy for their underlying MDS. [ Time Frame: throughout the study ]
- Trough pharmacokinetic parameters of deferasirox in patients with MDS [ Time Frame: throughout the study ]
- Drug accountability [ Time Frame: through out the study ]
