Trial Outcomes & Findings for Study of RTXM83 Plus CHOP Chemotherapy Versus a Rituximab Plus CHOP Therapy in Patients With Non Hodgkin's Lymphoma (NCT NCT02268045)

NCT ID: NCT02268045

Last Updated: 2019-09-26

Results Overview

Per International Working Group (IWG) revised criteria for Malignant Lymphomas (Cheson et al. 2007) and assessed by positron-emission tomography scan, or by computed tomography scan and/or magnetic resonance imaging if Positron Emission Tomography (PET) scan was not feasible. Tumor response was classified according to the International Working Group criteria, as Complete Remission (CR): Complete disappearance of all detectable clinical evidence of disease and disease-related symptoms if present before therapy; Partial Response (PR): At least a 50% decrease in sum of the product of the diameters of up to six of the largest dominant nodes or nodal masses; Stable disease (SD) or; Progressive disease. Response rate was the sum of CR and PR.

Timeframe: Cycle 1 (first dose): Day 1 (pre-dose, mid-infusion), Day 8 and Day 15

Compare the pharmacokinetic (PK) parameter (AUC 0-∞) calculated from start of the first infusion until start of the second infusion (i.e. at Cycle 1) in a population PK model. For the PK similarity assessments, regulatory guidelines on bioequivalence were followed whereby two treatments are judged not to be different from one another if the 90% confidence interval (CI) of the ratio between the geometric means of the measure (AUC 0-∞ ) falls completely within the range 80%-125%.

Population: Data were provided for the number of samples available at each visit.

CD19 and CD20 are proteins found on the cell surface of B cells, and they can be detected in peripheral blood by flow cytometry. Flow cytometry of peripheral blood was performed for immediate analysis of cells with cluster of differentiation 19 (CD19+) and CD20+. To compare the percent Change From Baseline ((Cycle 1 pre-dose) in pharmacodynamic markers (CD19+ and CD20+ Cells) in Peripheral Blood achieved in RTXM83 and Mabthera® arms at Cycle 1 end of infusion (EOI), 6 months and 9 months after last dose of treatment.
