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.

Description
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.
Arm Group Label
Moderate Adult Cohort
Arm Group Type
Other
Description
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.
Arm Group Label
Adults cohort with high iron overload
Arm Group Type
Other
Description
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.

Conditions
Conditions usually refer to a disease, disorder, syndrome, illness, or injury. In ClinicalTrials.gov,
conditions include any health issue worth studying, such as lifespan, quality of life, health risks, etc.
Interventions
Interventions refer to the drug, vaccine, procedure, device, or other potential treatment being studied.
Interventions can also include less intrusive possibilities such as surveys, education, and interviews.
Study Phase
Most clinical trials are designated as phase 1, 2, 3, or 4, based on the type of questions
that study is seeking to answer:
In Phase 1 (Phase I) clinical trials, researchers test a new drug or treatment in a small group of people (20-80) for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
In Phase 2 (Phase II) clinical trials, the study drug or treatment is given to a larger group of people (100-300) to see if it is effective and to further evaluate its safety.
In Phase 3 (Phase III) clinical trials, the study drug or treatment is given to large groups of people (1,000-3,000) to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
In Phase 4 (Phase IV) clinical trials, post marketing studies delineate additional information including the drug's risks, benefits, and optimal use.
These phases are defined by the Food and Drug Administration in the Code of Federal Regulations.
