{Reference Type}: Clinical Trial, Phase I {Title}: Phase Ib study of sabatolimab (MBG453), a novel immunotherapy targeting TIM-3 antibody, in combination with decitabine or azacitidine in high- or very high-risk myelodysplastic syndromes. {Author}: Brunner AM;Esteve J;Porkka K;Knapper S;Traer E;Scholl S;Garcia-Manero G;Vey N;Wermke M;Janssen JJWM;Narayan R;Fleming S;Loo S;Tovar N;Kontro M;Ottmann OG;Naidu P;Sun H;Han M;White R;Zhang N;Mohammed A;Sabatos-Peyton CA;Steensma DP;Rinne ML;Borate UM;Wei AH; {Journal}: Am J Hematol {Volume}: 99 {Issue}: 2 {Year}: 2024 02 22 {Factor}: 13.265 {DOI}: 10.1002/ajh.27161 {Abstract}: The safety and efficacy of sabatolimab, a novel immunotherapy targeting T-cell immunoglobulin domain and mucin domain-3 (TIM-3), was assessed in combination with hypomethylating agents (HMAs) in patients with HMA-naive revised International Prognostic System Score (IPSS-R) high- or very high-risk myelodysplastic syndromes (HR/vHR-MDS) or chronic myelomonocytic leukemia (CMML). Sabatolimab + HMA had a safety profile similar to that reported for HMA alone and demonstrated durable clinical responses in patients with HR/vHR-MDS. These results support the ongoing evaluation of sabatolimab-based combination therapy in MDS, CMML, and acute myeloid leukemia.
