This clinical trial is focused on studying a condition known as myelodysplastic syndrome (MDS), specifically a type called lower-risk MDS with ring sideroblasts (MDS-RS). MDS is a group of disorders caused by poorly formed or dysfunctional blood cells. The study is investigating the effectiveness and safety of a treatment called luspatercept, which is also known by its code name ACE-536. Luspatercept is a medication that is given as an injection under the skin and is designed to help improve anemia, a condition where the body does not have enough healthy red blood cells.
The purpose of this study is to see if luspatercept can help patients with lower-risk MDS-RS who need regular red blood cell transfusions. These patients have not responded well to other treatments that stimulate the production of red blood cells. The study will follow participants over a period of 24 weeks to see if they can achieve independence from red blood cell transfusions. This means that the patients would not need transfusions to maintain healthy red blood cell levels during this time.
Participants in the study will receive luspatercept injections and will be monitored for any changes in their need for red blood cell transfusions, as well as any side effects they may experience. The study will also look at other outcomes, such as changes in hemoglobin levels, which is a protein in red blood cells that carries oxygen, and overall survival. The goal is to determine if luspatercept can provide a safe and effective treatment option for patients with lower-risk MDS-RS.
