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).[1][2][3]
Route: IV
Extravasation: no information

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]

History of changes in FDA indication

  • 11/26/1997: Initial FDA approval for the treatment of patients with relapsed or refractory low-grade or follicular, CD20 positive, B-cell non-Hodgkin’s lymphoma.
  • 10/19/2012: FDA approved for 90-minute infusion in previously untreated follicular Non-Hodgkin lymphoma (NHL) and diffuse large B-cell lymphoma (DLBCL) starting with cycle 2:[6]
    • Patients who do not experience a grade 3 or 4 infusion related adverse event during cycle 1 may undergo a 90-minute infusion when used as part of a glucocorticoid-containing chemotherapy regimen. In cycle 2, 20% of the total dose is to be given over the first 30 minutes, and the remaining 80% of the total dose is to be given over the last 60 minutes. If this 90-minute infusion is tolerated, the same rate can be used for remaining cycles of the treatment.[1][7][8]
