Addition of rituximab to fludarabine and cyclophosphamide in patients with chronic lymphocytic leukaemia: a randomised, open-label, phase 3 trial.
2010
On the basis of promising results that were reported in several phase 2 trials, we investigated whether the addition of the monoclonal antibody rituximab to first-line chemotherapy with fludarabine and cyclophosphamide would improve the outcome of patients with chronic lymphocytic leukaemia.Treatment-naive, physically fit patients (aged 30-81 years) with CD20-positive chronic lymphocytic leukaemia were randomly assigned in a one-to-one ratio to receive six courses of intravenous fludarabine (25 mg/m(2) per day) and cyclophosphamide (250 mg/m(2) per day) for the first 3 days of each 28-day treatment course with or without rituximab (375 mg/m(2) on day 0 of first course, and 500 mg/m(2) on da…
Associations of ofatumumab exposure and treatment outcomes in patients with untreated CLL receiving chemoimmunotherapy
2016
Relationships between patient characteristics, ofatumumab pharmacokinetics, and treatment outcomes were investigated in this phase 2 trial of ofatumumab plus fludarabine and cyclophosphamide (FC) in untreated chronic lymphocytic leukemia. Patients were randomized 1:1 to receive 500 or 1000 mg ofatumumab (Cycle 1; 300 mg) plus FC every 4 weeks for six cycles. Median C(max) and C(trough) values were similar at Cycle 1 regardless of the ultimate clinical outcome. At later doses, these values were higher for patients with complete response (CR) than for other patients. Higher C(max) and C(trough) values at Cycles 3 and 6 were significantly associated with an increased likelihood of CR, whereas …
Epidemiological Characterization and Determination of TP53 and IGHV Mutational Status of a Large Series of Previously-Untreated Chronic Lymphocytic L…
2021
Abstract Introduction: Among the genetic lesions described in chronic lymphocytic leukemia (CLL), TP53 and IGHV mutational status are well-established prognostic biomarkers. While mutations resulting in dysregulation of TP53 are associated with chemo-resistance, mutated IGHV (IGHV-M) identifies a good prognosis and unmutated (IGHV-UM) is associated with an aggressive clinical outcome. Thus, molecular assessment of TP53 and IGHV mutational status is recommended to make treatment decisions. Moreover, 30% of CLL patients have a highly homologous complementarity-determining region 3 (CDR3), allowing their classification in subsets based on the stereotypical B-cell receptor immunoglobulins (BcR …
