Pharmacology
Rituximab is a chimeric murine/human IgG1 kappa monoclonal antibody that binds the CD20 antigen on pre-B and mature B-lymphocytes, mediating B-cell lysis via complement dependent cytotoxicity (CDC) and antibody dependent cell mediated cytotoxicity (ADCC).
PI3K-delta inhibitor; idelalisib blocks BCR, CXCR4, and CXCR5 signaling pathways to induce apoptosis and inhibit proliferation in normal and malignant B-cells, and reduces chemotaxis and adhesion of lymphoma cells.
