Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults diagnosed with very low, low, or intermediate-risk MDS who are not dependent on blood transfusions and have not previously received erythropoiesis-stimulating agents.

Probably not a fit

Patients who are transfusion dependent or have received prior erythropoiesis-stimulating agents may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the efficacy and safety of Luspatercept compared to Epoetin Alfa in treating anemia in adults with Myelodysplastic Syndromes (MDS) who are not receiving blood transfusions. Participants must have a documented diagnosis of MDS classified as very low, low, or intermediate-risk and must be naive to erythropoiesis-stimulating agents. The study will assess the impact of these treatments on anemia symptoms and overall health outcomes in this specific patient population.

Why it matters

Potential benefit: If successful, this study could provide a new effective treatment option for patients with anemia due to MDS, potentially improving their quality of life.

How similar studies have gone: Other studies have shown promise in using Luspatercept for treating anemia in MDS, indicating a potential for success with this approach.

Inclusion Criteria

* Participant has documented diagnosis of MDS according to World Health Organization (WHO) 2016 that meet IPSS-R classification of very low, low, or intermediate-risk disease, (intermediate-risk of ≤ 3.5 IPSS-R score) confirmed via bone marrow aspirate and:.

  i) \< 5% blasts in bone marrow and \< 1% blasts in peripheral blood.
* Participant is not transfusion dependent (NTD) based on IWG2018 criteria.
* Participant is erythropoiesis-stimulating agent naive. Participants may be randomized at the investigator's discretion if the participant received no more than 2 prior doses of epoetin alfa, epoetin alfa biosimilar, or darbepoetin alfa, with the last dose at least 8 weeks prior to randomization.
* Participant has a baseline endogenous serum erythropoietin (sEPO) level of ≤ 500 U/L.
* Participant has symptoms of anemia:.

  i) Participant records a severity score of "moderate" or greater on at least 1 PGI-S item of fatigue, weakness, shortness of breath, or dizziness performed during the screening period.
* Participant has a baseline Hb concentration prior to randomization of ≤ 9.5 g/dL. The baseline Hb will be calculated using the mean of the two lowest available Hb measurements within 16 weeks prior to randomization and must include at least one central lab Hb reading done within the screening period (no more than 35 days before randomization). The two Hb measurements must have been performed at least seven days apart. Hb levels less than 21 days following RBC transfusion should not be used. Split samples for local assessments are not required.

Exclusion Criteria

* Participant with secondary MDS (that is, MDS that is known to have arisen as the result of chemical injury or treatment with chemotherapy and/or radiation for other diseases).
* Participant with known history of diagnosis of AML.
* Participant with history of cerebrovascular accident (including ischemic, embolic, and hemorrhagic cerebrovascular accident), transient ischemic attack, deep venous thrombosis (including proximal and distal), pulmonary or arterial embolism, arterial thrombosis, or other venous thrombosis within 6 months prior to randomization.
* Participant with a history of pure red cell aplasia and/or antibody against erythropoietin.
* Other protocol-defined Inclusion/Exclusion criteria apply.
