MEN1112 / Menarini, Oxford BioTherap - LARVOL DELTA

[VIRTUAL] MEN1112/OBT357, a first-in-class humanized de-fucosylated monoclonal antibody targeting CD157 positive cells in acute myeloid leukemia and myelodysplastic syndrome (AACR 2021) - P1 | "Importantly, we confirmed in ex vivo experiments, the depletion of these immunosuppressive cells by MEN1112/OBT357. Overall, our data demonstrate that MEN1112/OBT357 is a novel antibody with potent ex vivo activity against blast cells in AML and MDS patients, suggesting a potential contribution of MEN1112/OBT357 in altering the immunosuppressive environment in the bone marrow niche."

CD157: From Myeloid Cell Differentiation Marker to Therapeutic Target in Acute Myeloid Leukemia. (PubMed, Cells) - "The aim of this review is to provide an overview of the immunoregulatory functions of human CD157/BST-1 in physiological and pathological conditions. We then focus on CD157 expression in hematological tumors highlighting its emerging role in the interaction between acute myeloid leukemia and extracellular matrix proteins and its potential utility for monoclonal antibody targeted therapy in this disease."
