Rituximab, sold under the brand name Rituxan among others, is a monoclonal antibody medication used to treat certain autoimmune diseases and types of cancer. [18] It is used for non-Hodgkin lymphoma, chronic lymphocytic leukemia (in children and adults, but not recommended in elderly patients), rheumatoid arthritis, granulomatosis with polyangiitis, idiopathic thrombocytopenic purpura ...
An example is rituximab, a therapeutic antibody used to treat chronic lymphocytic leukemia, recognizes the CD20 molecule expressed by tumor cells and leads to their elimination. [15] However, using too much of the antibody results in part from the removal of rituximab-CD20 complexes from the tumor cell surface by monocytes through trogocytosis.
More recently, the immunotherapy drug, rituximab has been added to the CHOP chemotherapy regiment to form the R-CHOP chemoimmunotherapy regimen. [2] Rituximab is a monoclonal antibody that binds to the CD20 protein on, e.g. B-cells, and by doing so targets these cells for attack by the hosts adaptive immune system. [13]
CD20 is the target of the mAbs rituximab, ocrelizumab, obinutuzumab, ofatumumab, ibritumomab tiuxetan, tositumomab, and ublituximab, which are all active agents in the treatment of all B cell lymphomas, leukemias, and B cell-mediated autoimmune diseases.
Participants in the VEN+R arm completed a 5-week ramp-up venetoclax schedule and then received venetoclax 400 mg once daily for 24 months measured from the rituximab start date. [17] Rituximab was initiated after venetoclax ramp-up and given for 6 cycles (375 mg/m2 intravenously on cycle 1 day 1 and 500 mg/m2 intravenously on day 1 of cycles 2 ...
Mechanism of action Indications Toxicity; Abciximab: A monoclonal antibody that binds to the glycoprotein receptor IIb/IIIa on activated platelets, preventing aggregation Acute coronary syndromes, percutaneous transluminal coronary angioplasty Bleeding, thrombocytopenia: Anakinra (Kineret) A recombinant version of the Interleukin 1 receptor ...
Several monoclonal antibody drugs such as Rituximab manipulate the ADCC pathway to eradicate cancer cells. Firstly, the Fab region of the antibodies (tip of the Y-shaped-antibody) first binds to the epitope of the pathogens or the immunoreceptors of cancer cells; whereas the Fc region (stem of the antibody) binds to natural killer cells to ...
This may be because of lack of funding to go through the approval process. Some doctors prescribe them off-label or under the schema of open label research. Examples of MS drugs used off label include: rituximab - Monoclonal antibody against CD20. According to some sources it has a better efficacy vs. safety profile than most approved drugs. [76]
