Pharmacology
Asparaginase erwinia chrysanthemi (recombinant)-rywn is a recombinant bacterial enzyme that catalyzes the conversion of L-asparagine to aspartic acid and ammonia, depleting plasma asparagine and killing leukemic cells that depend on exogenous asparagine for survival due to low asparagine synthetase expression.
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).
