Resumen

El objetivo principal de este estudio es evaluar la eficacia de elritercept para reducir la necesidad de transfusiones de glóbulos rojos (GR) y su seguridad en comparación con epoetina alfa. Otros objetivos son determinar si elritercept mejora el cansancio notificado por los participantes sin necesidad de transfusión de GR en comparación con epoetina alfa, la carga transfusional de GR y la calidad de vida en comparación con epoetina alfa. El estudio también tiene como objetivo determinar el grado de respuesta inmunitaria a elritercept. Asimismo, se evaluarán los problemas médicos (seguridad) asociados a elritercept.

Participant requires RBC transfusion, as documented by the following criteria. A transfusion requirement of 2 to 6 pRBCs units/8 weeks confirmed for a minimum of 8 weeks immediately preceding randomization.
• Hgb levels at the time of or within 3 days prior to administration of a RBC transfusion must have been less than or equal to (≤) 9.0 grams per deciliter (g/dL) (5.6 millimoles per liter (mmol/L)) with symptoms of anemia (or ≤7 g/dL \[4.3 mmol/L\] in the absence of symptoms) in order for the transfusion to be counted towards meeting eligibility criteria.
• RBC transfusions administered when hemoglobin (Hgb) levels were \>9.0 g/dL (or \>7 g/dL in the absence of symptoms) and/or RBC transfusions administered for elective surgery, infections or bleeding events will not qualify as a required transfusion for the purpose of meeting eligibility criteria or stratification.
Hgb \<11.0 g/dL (6.8 mmol/L) after last RBC transfusion preceding randomization. Local laboratory is acceptable to facilitate randomization.
