Abstract

Patients with higher-risk myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML) unfit for hematopoietic stem cell transplantation have poor outcomes. Novel therapies that provide durable benefit with favorable tolerability and clinically meaningful improvement in survival are needed. T-cell immunoglobulin domain and mucin domain-3 (TIM-3) is an immuno-myeloid regulator expressed on immune and leukemic stem cells in myeloid malignancies. Sabatolimab is a novel immunotherapy targeting TIM-3 with a potential dual mechanism of reactivating the immune system and directly targeting TIM-3+ leukemic blasts suppressing the growth of cancer cells. Here, we describe the aims and design of the phase III STIMULUS-MDS2 trial, which aims to demonstrate the potential for sabatolimab plus azacitidine to improve survival for patients with higher-risk MDS and CMML-2 (NCT04266301).
