Primary Outcome Measures:
  • change in cardiac iron content as measured by T2*.Cardiac T2* is the relaxation time, a cardiac magnetic resonance parameter expressed in milliseconds (ms)inversely correlated to the amount of iron in the heart. [ Time Frame: month 12 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of patients achieving MRI-measured cardiac T2* ≥ 10 ms (but at least 10% relative increase in cardiac T2* from baseline) [ Time Frame: Months 6, 12, 18 and 24 ] [ Designated as safety issue: No ]
  • Change in cardiac iron content reflected by change in MRI-measured cardiac T2* [ Time Frame: Months 6, 18 and 24 ] [ Designated as safety issue: No ]
  • change in MRI-measured parameters of the left and right ventricle (left and right heart) [ Time Frame: Months 6, 12, 18 and 24 ] [ Designated as safety issue: No ]
  • occurrence and severity of adverse events and of abnormal laboratory and special safety assessments (laboratory safety values, ECG, vital signs, auditory and ophthalmic examinations) [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
  • time to achieve MRI-measured cardiac T2* ≥ 10 ms [ Time Frame: 24 months ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:

  • Patients with β-thalassemia major or Diamond-Blackfan anemia (DBA) or congenital sideroblastic anemia on chronic transfusion therapy
  • Myocardial T2* value that is ≥ 5 and < 10 ms
  • Left ventricular ejection fraction (LVEF) ≥ 56% as determined by Magnetic resonance imaging (MRI)
  • Lifetime history of at least 50 units of red blood cell transfusions, and must be receiving at least ≥ 8 units/yr of red blood cell transfusions

Exclusion Criteria:

  • Patients with clinical symptoms of cardiac dysfunction (shortness of breath at rest or exertion, orthopnea, exercise intolerance, lower extremity edema, arrhythmias)
  • Patients unable to undergo study assessments including MRI
  • Patients with serum creatinine greater than Upper limit of normal ULN)range or with significant proteinuria as indicated by a urinary protein/creatinine ratio (UPCR) ≥1.0 mg/mg in a non-first void urine sample at baseline.

Other protocol-defined inclusion/exclusion criteria may apply
