Summary

This trial is looking at whether or not MBG-453 is effective in treating myelodysplastic syndromes (MDS).

Who is the study for?
This trial is for adults with lower risk Myelodysplastic Syndromes (MDS) who need regular red blood cell transfusions, have not responded to previous treatments, or can't tolerate other medications. It's also open to those with specific genetic changes in their MDS and no available standard treatment options.
What is being tested?
The study is testing MBG453, a humanized monoclonal antibody designed to treat MDS. Researchers want to see how effective it is at improving the condition of patients who haven't had success with other therapies.
What are the potential side effects?
While the side effects of MBG453 are not detailed here, as a monoclonal antibody, potential side effects could include allergic reactions, infusion-related symptoms like fever or chills, fatigue, and possible impacts on liver function.
