Pangalis GA, Kyrtsonis MC, Kontopidor FN, et al. We therefore conducted a phase 2 study using thalidomide and rituximab in symptomatic Waldenstrom macroglobulinemia (WM) patients naive to either agent. Synopsis: Thalidomide-rituximab was administered to 25 symptomatic patients (20 previously untreated) with Waldenstrom macroglobulinemia. ... how rituximab (Rituxan) affects the immune system, I think BTK inhibitors affect the immune system just a little bit less degree, at a lesser degree than what rituximab does. Symptomatic, previously untreated patients will receive SOC bendamustine and rituximab for 6 28-day cycles. If you have Waldenstrom macroglobulinemia, your bone marrow produces too many abnormal white blood cells that crowd out healthy blood cells. It can affect people of all ages and is the most common blood cancer.
