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 ...
Dose de-escalation below the starting doses in case of poor patient's chemotherapy tolerability applies to cyclophosphamide only. If the nadir ANC > 500/μL, then the doses of etoposide, doxorubicin, and cyclophosphamide for the next cycle are all increased by 20% over the doses used in the previous cycle.
R-miniCHOP is indicated in elderly patients (>80 years) with diffuse large B-cell lymphoma due to less toxicity from the reduced dose in comparison to R-CHOP.. R-Maxi-CHOP is used in mantle cell lymphoma and is given in 21-day intervals, alternating with R-HDAC (rituximab + high-dose cytarabine).
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.
The observed time in remission is the time from start of CR to data cut-off date or relapse from CR. [18] In a phase 3 study of azacitidine and venetoclax in untreated acute myeloid leukemia not eligible for standard induction chemotherapy, the addition of venetoclax to azacitidine resulted in an improvement in median overall survival (14.7 ...
Results from the 2-year randomized, placebo-controlled, double-blind, multicenter RituxME trial comparing multiple brands of rituximab infusions with placebo in 151 ME/CFS patients concluded that “B-cell depletion using several infusions of rituximab over 12 months was not associated with clinical improvement in patients with ME/CFS,” and ...
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
