Beta-Thalassemia, Hemosiderosis
Conditions
Keywords
Thalassemia (beta-thal. major), Transfusional hemosiderosis, Deferasirox, Beta-thalassemia major patients, Unable to be chelated with deferoxamine or deferiprone
Brief summary
Because patients with beta-thalassemia are unable to actively eliminate iron from the body, toxic and eventually lethal levels of iron can accumulate as a result of repeated blood transfusions. This study will evaluate the efficacy, safety and tolerability of deferasirox.

Eligibility
Inclusion criteria
* Beta-thalassemia outpatients with transfusional hemosiderosis and unable to be chelated with deferoxamine (DFO) due to DFO being contra-indicated and/or due to documented unacceptable toxicity of DFO or documented poor response to DFO despite proper compliance, or documented non-compliance to DFO, with serum ferritin ≥ 500 ng/ml and LIC ≥ 2 mg/Fe/g dw liver * Beta-thalassemia outpatients with transfusional hemosiderosis treated with deferiprone
Exclusion criteria
* Means levels of ALT \> 300 U/L * Serum creatinine above upper limit of normal * Active hepatitis C or chronic hepatitis B receiving specific treatment
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Liver Iron Concentration (as measured by biopsy) | at baseline and after 1 yeor of ICL670 treatment |
Secondary
| Measure | Time frame |
|---|---|
| Iron balance, i.e. Total Body Iron Excretion (based on the iron influx as determined by the amount of red cells transfused and the change in total body iron (TBI) stores) | after 1 year of ICL670 treatment |
| Putative surrogate markers such as serum ferritin serum iron, serum transferrin and transferrin saturation | monthly assessments for 1 year |
| Adverse events | during 1 year ICL670 treatment |
| hematology and biochemistry, urinalysis | monthly assessments for 1 year ICL670 treatment |
| ECG and Echocardiography | 6-monthly for 1 year ICL670 treatment |
