简要总结
This is a prospective, multicenter phase II trial designed to determine efficacy and safety of Bortezomib plus Rituximab plus Bendamustine in patients with relapsed/refractory Waldenstrom's Macroglobulinemia.
详细描述
The progression free survival (PFS) expected for lymphoplasmacytic/lymphoplasmocytoid lymphoma/Waldenstrom macroglobulinemia with the same characteristics indicated into the study and treated with standard Rituximab plus chemotherapy may be estimated to be 50% at 18 months.
The Investigators would consider a positive result to increase 18 months-PFS rate from 50 to 65%.

研究组 & 干预措施
Bortezomib-Rituximab-Bendamustine
Bortezomib-Rituximab-Bendamustine (BRB) combination in patients with relapsed/refractory lymphoplasmocytic/lymphoplasmocytoid lymphoma/Waldenstrom macroglobulinemia after one line of therapy.

结局指标
主要结局
Progression Free Survival (PFS)
时间窗: 18 months
This is a prospective, multicenter phase II trial designed to determine efficacy and safety of Bortezomib plus Rituximab plus Bendamustine in patients with relapsed/refractory Waldenstrom's Macroglobulinemia. Primary Objective is to assess whether the experimental treatment achieves an absolute increase of PFS rate from 50 to 65% at 18 months with respect to the standard treatment. PFS is measured from the beginning of therapy to the date of disease progression, relapse or death from any cause. Patients without any relapse at the end of the follow-up will be censored at their last assessment date.
