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).
ONCASPAR is a PEGylated L-asparaginase that catalyzes the conversion of L-asparagine to aspartic acid and ammonia, depleting plasma asparagine and killing leukemic cells that have low asparagine synthetase expression and depend on an exogenous asparagine source for survival.
