TNF-alpha antagonist; infliximab-abda is a chimeric IgG1kappa monoclonal antibody that neutralizes TNF-alpha by binding with high affinity to soluble and transmembrane forms of TNF-alpha, inhibiting receptor binding and suppressing downstream pro-inflammatory activity.

Rituximab-pvvr is a chimeric monoclonal antibody that targets the CD20 antigen on pre-B and mature B-lymphocytes, mediating B-cell lysis through complement dependent cytotoxicity (CDC) and antibody dependent cell mediated cytotoxicity (ADCC).
