Brief Summary:
This was a prospective, single-arm, multicenter, national, phase II clinical study. The purpose of this Phase II study was to examine the safety and efficacy of deferasirox to decrease iron overload (IOL) in the posttransplant period in patients with beta-thalassemia major.

Condition or disease Intervention/treatment Phase

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Number of Participants With Adverse Events, Serious Adverse Events and Deaths as a Measure of Safety and Tolerability [ Time Frame: 12 months ]
    To determine the safety; incidence, type and severity of adverse events including renal, hepatic, biochemistry and hematologic parameters of deferasirox in the treatment of iron overload after hematopoietic stem cell transplantation (HSCT) in patients with beta-thalassemia major in 12 months period


Secondary Outcome Measures :
  1. Change in Serum Ferritin Level. [ Time Frame: Baseline, 12 Months ]
    Blood samples were collected and serum levels were assessed at study baseline (BL) and at 12 months.

  2. Change in the Further Parameters of Iron Overload (Liver Iron Concentration by Magnetic Resonance Imaging (MRI Examination) [ Time Frame: Baseline, 12 month ]
    Liver Iron Concentration (LIC) values between 3 and 7 mg Fe / g dry weight are indicative of mild iron deposition, while values between 7 and 15 mg Fe / g dry weight are indicative of moderate iron deposition which have been associated with liver disease. Values >15 mg Fe/g dry weight are indicative of severe iron deposition which is associated with progressive liver fibrosis, increased morbidity and mortality

  3. The Percentage of Patients Reaching Serum Ferritin Levels Lower Than 500 μg/L [ Time Frame: Week 28 and Week 52 ]
    Serum Ferritin values between 1000-2500 μg/L are indicative of mild to moderate iron overload while values >2500 μg/L are indicative of severe iron overload and levels constantly higher than 2500 μg/L has been shown to to increase the risk of cardiac complications and endocrine disease. Maintaining levels <1000 μg/L is associated with increased survival and less morbidity.

  4. Change in the Further Parameters of Iron Overload (Cardiac Iron Concentration by Magnetic Resonance Imaging (MRI Examination) [ Time Frame: Baseline, 12 month ]
    Cardiac MRI values between 10 to 20 milliseconds (ms) are indicative of moderate cardiac iron deposition associated with declining left ventricular ejection fraction and arrhythmias while values <10 ms are indicative of deposition sufficient to risk cardiac decompensation and associated with overt heart failure and mortality.
