Brief Summary:
This is a small pilot study looking at the safety of giving combination chelation with Exjade and Desferal to 15 patients. The hypothesis is that combination chelation is safe in decreasing overall iron in patients with thalassemia.

Condition or disease Intervention/treatment Phase

Arm Intervention/treatment
Child Cohort
This is the cohort in the study for children ages 8-18 years old. All subjects in this arm must have Liver Iron by SQUID of between 5-15mg/g dry liver and have a documented endocrinopathy or cardiac finding (low T2* or decreased cardiac function). All subjects in this arm will receive 7 days per week of Exjade and 3-5 days per week of Desferal.
 Drug: Combo Chelation with Deferasirox (Exjade) and Desferal (DFO)
All subjects will be given Exjade 7 days per week 20-30mg/kg and Deferoxamine 3-7 days per week 50mg/kg. Days per week are dependent on how much iron overload subject has.
Other Names:
  • Exjade, ICL670 (deferisirox)
  • DFO, Desferal (deferoxamine)
Moderate Adult Cohort
Adults in this arm will have moderate iron overload,defined as SQUID of 5-15mg/g dry weight. They will also have to have a documented endocrinopathy or cardiac finding (low T2*). All subjects in this cohort will receive 7 days per week of Exjade (20-30mg/kg) and Desferal (50mg/kg)3-5 days per week.
 Drug: Combo Chelation with Deferasirox (Exjade) and Desferal (DFO)
All subjects will be given Exjade 7 days per week 20-30mg/kg and Deferoxamine 3-7 days per week 50mg/kg. Days per week are dependent on how much iron overload subject has.
Other Names:
  • Exjade, ICL670 (deferisirox)
  • DFO, Desferal (deferoxamine)
Adults cohort with high iron overload
Adults with high iron overload defined as over 15mg/g dry liver. No cardiac finding or endocrinopathy necessary. Subjects in this cohort will receive Exjade 20-30mg/kg 7 days per week and Desferal (50mg/kg)5-7 days per week.
 Drug: Combo Chelation with Deferasirox (Exjade) and Desferal (DFO)
All subjects will be given Exjade 7 days per week 20-30mg/kg and Deferoxamine 3-7 days per week 50mg/kg. Days per week are dependent on how much iron overload subject has.
Other Names:
  • Exjade, ICL670 (deferisirox)
  • DFO, Desferal (deferoxamine)
