{"denomUnitsSelected":"Participants","description":"15 protein/genes associated with BTK-signaling will be assessed and their levels from baseline samples will be compared with levels from samples during treatment. Changes over time will be evaluated using paired sample approaches (Wilcoxon signed rank test). Baseline levels will be correlated with response (responder versus \\[vs.\\] non-responder) using Wilcoxon rank sum tests.","reportingStatus":"NOT_POSTED","timeFrame":"Up to 5 years","title":"BTK Signaling Proteins (Western Blot and Densitometric Quantification) and Gene Expression (Quantitative Real-time Polymerase Chain Reaction [PCR]) Examined in CD19/CD138+ Waldenstrom Macroglobulinemia (WM) Cells","type":"OTHER_PRE_SPECIFIED"}
