CD38 is a transmembrane glycoprotein expressed on the surface of different cell lines with several functions (receptor, adhesion molecule, ectoenzyme). Based on its high expression in multiple myeloma cells, CD38 is one of the main molecules used in the target therapy age. Daratumumab is the first fully human monoclonal antibody tested in clinical trials, showing efficacy in relapsed/refractory multiple myeloma patients, especially in combination with immunomodulants and/or proteasome inhibitors. The synergic effect concerns multiple myeloma cells as well as the microenvironment (NK cells, macrophage, regulatory B/T cells and CD8+ effector cells). Therefore, the anti-multiple myeloma activity of Daratumumab greatly depends on the immune system: this is the reason why several ongoing clinical trial are testing its efficacy in the naïve patients, with a more effective immune system.
