Outcome Measures
Primary Outcomes (1)
The Percentage of Patients in Each Treatment Group Who Experience Post-dose Increases in Liver Enzyme Levels That Are Considered a Safety Concern.
Levels of the liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST) will be assessed throughout the study to determine if any patients have post-dose increases that are considered to be a safety concern. The criteria for being considered a safety concern are meeting one of the following: * For a patient whose level was within the normal range at baseline, the criterion is reaching a value of 5 times the upper limit of normal (ULN) * For a patient whose level was above the ULN at baseline, the criterion is reaching either 5 times the baseline value or 10 x ULN
Day 28
Secondary Outcomes (2)
The Percentage of Patients in Each Treatment Group Who Report Post-dose Occurrences of Gastrointestinal (GI) Distress.
Day 28
The Percentage of Patients in Each Group Who Indicate That They Prefer the Deferiprone DR Formulation Over the Immediate-release Formulation.
Day 28
Study Arms (2)
Low dosage
EXPERIMENTALPatients in this group will receive a total daily dosage of deferiprone DR tablets that is closer to 75 mg/kg/day. The total dosage will be divided into two equal parts, taken about 12 hours apart.
High dosage
EXPERIMENTALPatients in this group will receive a total daily dosage of deferiprone DR tablets that is closer to 100 mg/kg/day. The total dosage will be divided into two equal parts, taken about 12 hours apart.

Eligibility Criteria
You may qualify if:
- Male or female aged ≥ 18 years.
- Diagnosis of thalassemia syndrome, sickle cell disease, or other disorder requiring a regular regimen of red blood cell transfusions.
- On a stable regimen (≥3 months) of Ferriprox tablets for the treatment of systemic iron overload.
- Absolute neutrophil count ≥1.5 x 10\^9/L at screening.
- A record of at least 12 measured alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels.
You may not qualify if:
- Receipt of any iron chelator other than Ferriprox (i.e., combination therapy) in the last 3 months, or planning to receive it at any time during the period of the study.
- ALT and/or AST value \> 5 times the upper limit of normal (ULN) at screening
- Active case of hepatitis B or C at screening.
