Clinical Studies - Deferasirox

Pivotal and real-world deferasirox studies: LIC reduction, ferritin trends and cardiac T2* improvement in thalassemia, SCD and MDS.


The clinical evidence supporting deferasirox spans pivotal randomised trials, long-term extension studies and real-world post-authorisation experience across thalassemia, sickle-cell disease and myelodysplastic syndromes (MDS).

Pivotal Programme Overview #

StudyPopulationKey EndpointOutcome
Pivotal randomised vs. deferoxamineAdults & pediatrics with transfusion-dependent thalassemiaChange in LIC after 1 yearNon-inferior LIC reduction at appropriate doses (20-30 mg/kg/day); ferritin reductions in heavily-loaded subset
Sickle-cell disease programmeAdults & pediatrics with SCD on chronic transfusionLIC reduction; ferritin trendSignificant reductions in LIC and ferritin over 12 months
EPIC (Evaluation of Patients' Iron Chelation with Exjade)Large open-label registry across multiple anemiasReal-world ferritin reductionDemonstrated population-level ferritin reduction at clinically used doses
MDS sub-populationLower-risk MDS with transfusional iron overloadFerritin reduction; safety signalsFerritin reductions; tolerability considerations including cytopenia monitoring
Cardiac iron studiesPatients with myocardial iron loading (T2* < 20 ms)Cardiac T2* improvementImprovement in cardiac T2* with sustained multi-year therapy

Representative Numerical Outcomes #

  • Liver iron concentration (LIC): reductions of approximately 1-9 mg Fe/g dry weight over 12 months at 20-30 mg/kg/day, dose-dependent.
  • Serum ferritin: mean reductions in the range of 500-1500 ng/mL across 12 months in heavily-loaded populations on adequate doses.
  • Cardiac T2*: sustained therapy associated with improvement from baseline values < 20 ms toward normal range over 24-36 months.

Note: precise numerical results depend on baseline iron burden, transfusion intensity and dose adherence; numerical ranges above are summary representations of published programme data and should not be substituted for the locally approved prescribing information.

Long-Term Safety Findings #

Long-term extension studies have characterised the safety profile of sustained chelation including the renal, hepatic, gastrointestinal and rare severe cutaneous reactions described on the Safety Profile page. The benefit-risk balance of long-term chelation in transfusion-dependent populations is well-established.
