PHASE3

A Study to Compare Elritercept With Epoetin Alfa to Treat Anemia in Adults With Very Low, Low, or Intermediate Risk Myelodysplastic Syndromes (MDS) Who Need Regular Blood Transfusions

Sponsor: Takeda

View on ClinicalTrials.gov

Summary

The main aim of this study is to assess how elritercept works in lowering the need for RBC (red blood cell) transfusions and how safe elritercept is when compared with epoetin alfa. Other aims are to learn if elritercept improves tiredness as reported by participants without needing RBC transfusion compared with epoetin alfa, the RBC transfusion burden and quality of life compared with epoetin alfa. The study also aims to find out the extent of the immune response to elritercept. The study will also check on the medical problems (safety) of elritercept.

Official title: A Phase 3, Multicenter, Open-Label, Randomized Trial to Compare the Efficacy and Safety of Elritercept Versus Epoetin Alfa for the Treatment of Anemia Due to IPSS-R Very Low, Low, or Intermediate Risk Myelodysplastic Syndromes in ESA-naïve Adult Participants Who Require Red Blood Cell Transfusions

Inclusion Criteria 1. Male or female participants aged ≥ 18 years or older at time of signing the informed consent form (ICF). 2. Able to understand the purpose and risks of the trial and voluntarily sign an ICF prior to any trial-related procedures being conducted and authorization to use protected health information and personal data in accordance to national and local privacy regulations. 3. Documented diagnosis of myelodysplastic syndrome(s) (MDS) according to WHO 2016 classification that meets International Prognostic Scoring System - Revised (IPSS-R) classification of very low-, low-, or intermediate-risk disease, confirmed by central laboratory independent reviewer prior to randomization. Hemoglobin (Hgb), platelet, and absolute neutrophil count (ANC) values should be collected greater than (\>) 14 days after red blood cell (RBC) transfusion or greater than (\>) 7 days after platelet transfusion, unless otherwise considered to be pretransfusion values. 4. Bone marrow less than (\<) 5% blasts in an evaluable bone marrow collected at screening and confirmed by central pathology independent reviewer. 5. Endogenous serum erythropoietin s (EPO) level of \<500 U/L. Should be results from blood samples collected \>14 days following an RBC transfusion to evaluate for eligibility unless considered pretransfusion values. 6. 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. 7. Hgb \<11.0 g/dL (6.8 mmol/L) after last RBC transfusion preceding randomization. Local laboratory is acceptable to facilitate randomization. 8. Eastern Cooperative Oncology Group score of 0, 1, or 2. Exclusion Criteria  1. Prior therapy with any of the following: 1.
