E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the effect of treatment with deferasirox combined with erythropoietin vs. erythropoietin alone on erythropoiesis after 12 weeks of treatment defined by hemoglobin levels |
Evaluar el efecto del tratamiento con deferasirox combinado con eritropoyetina comparado con eritropoyetina sola en la eritropoyesis después de 12 semanas de tratamiento definido por los niveles de hemoglobina |
|
E.2.2 | Secondary objectives of the trial |
Key secondary objective: To assess the effect of treatment with deferasirox combined with erythropoietin on hematologic improvement within 24 weeks of treatment in patients randomized to combination therapy at baseline defined by hemoglobin, platelets and neutrophil levels
Other secondary objectives as per protocol may apply. |
Evaluar el efecto del tratamiento con deferasirox combinado con eritropoyetina en la mejoría hematológica dentro de las 24 semanas posteriores al tratamiento en pacientes aleatorizados a la terapia combinada en la visita basal definida por los niveles de hemoglobina, plaquetas y neutrófilos
