Trial Outcomes & Findings for Thalidomide and Rituximab in Waldenstrom's Macroglobulinemia (NCT NCT00142116)

NCT ID: NCT00142116

Last Updated: 2014-06-02

Results Overview

Response determinations were made using modified consensus panel criteria from the Third International Workshop on WM, and response rates were determined on an evaluable basis. A complete response was defined as having resolution of all symptoms, normalization of serum IgM levels with complete disappearance of IgM paraprotein by immunofixation, and resolution of any adenopathy or splenomegaly. Patients achieving a partial response and a minor response were defined as achieving a more than or equal to 50% and more than or equal to 25% reduction in serum IgM levels, respectively. Patients with stable disease were defined as having less than 25% change in serum IgM levels, in the absence of new or increasing adenopathy or splenomegaly and/or other progressive signs or symptoms of WM. Progressive disease was defined as a greater than 25% increase in serum IgM level occurred from the lowest attained response value or progression of clinically significant disease-related symptom(s).
