Summary
Brief summary
The purpose of the study was to find out if the new drug sabatolimab when given in combination with azacitidine and venetoclax, was safe and had beneficial effects in participants with high or very high risk myelodysplastic syndrome (MDS) who were not suitable for treatment with intensive chemotherapy or a stem-cell transplant (HSCT).
