5. Non or ex-smoker (someone who has completely stopped smoking 6 months before study start)
6. For females, negative result on a serum pregnancy test.

Main Exclusion Criteria:

1. Absolute neutrophil count (ANC) <1.5x10^9/L.
2. History or presence of hypersensitivity to deferiprone or any related products.
3. History or presence of gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs.
