Rituximab and hyaluronidase human (Rituxan Hycela)

General information

Class/mechanism: Anti-CD20 antibody, chimeric murine/human monoclonal IgG1 kappa, which binds to CD20 (human B-lymphocyte-restricted differentiation antigen, Bp35), which is expressed on B-cells. The Fc domain recruits immune effector functions to mediate B-cell lysis. Possible mechanisms of cell lysis include complement-dependent cytotoxicity (CDC) and antibody-dependent cell mediated cytotoxicity (ADCC).
Route: SC* (Rituxan Hycela treatment should be initiated only after patients have received at least one full dose of a rituximab product by intravenous infusion)
Extravasation: neutral
