If after 12 weeks of treatment, erythroid improvement was inadequate, participants were switched to the combination arm. At any time when erythroid response was achieved, erythropoietin treatment was stopped until end of study. | | OG001 | Deferasirox + Erythropoietin Alpha | Starting dose was deferasirox dispersible tablet (DT) 10 mg/kg/day or deferasirox film-coated tablet FCT) 7 mg/kg/day in combination with erythropoietin 40,000 units/week. If after 4 weeks erythroid improvement was inadequate, erythropoietin dose was escalated to 60,000 units/week.
