Safety, tolerability, and acceptability of twice-daily dosing with deferiprone
delayed-release (DR) tablets in patients with systemic iron overload.

This study is looking at the safety, tolerability, and acceptability of twice-daily dosing
with deferiprone delayed-release (DR) tablets in patients with systemic iron overload who are
currently taking deferiprone immediate-release tablets (Ferriprox) three times a day.
Ferriprox doses range from 75 milligrams per kilogram of body weight (mg/kg) per day to 100
mg/kg per day. Half the patients in the study will be on a dosage that is closer to the low
end of the range, and half will be on a dosage that is closer to the high end. Both groups
will be switched for one month to deferiprone DR tablets at approximately the same total
daily dosage that they have been taking for Ferriprox.

Inclusion Criteria:

1. Male or female aged ≥ 18 years.

2. Diagnosis of thalassemia syndrome, sickle cell disease, or other disorder requiring a
regular regimen of red blood cell transfusions.

3. On a stable regimen (≥3 months) of Ferriprox tablets for the treatment of systemic
iron overload.

4. Absolute neutrophil count ≥1.5 x 10^9/L at screening.

5. A record of at least 12 measured alanine aminotransferase (ALT) and aspartate
aminotransferase (AST) levels.

Exclusion Criteria:

1. 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.

2. ALT and/or AST value > 5 times the upper limit of normal (ULN) at screening

3. Active case of hepatitis B or C at screening.
