Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Waldenstrom's Macroglobulinemia Drug: Bortezomib-Rituximab-Bendamustine Phase 2

Detailed Description:

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%.

Arm Intervention/treatment
Experimental: Bortezomib-Rituximab-Bendamustine
Bortezomib-Rituximab-Bendamustine (BRB) combination in patients with relapsed/refractory lymphoplasmocytic/lymphoplasmocytoid lymphoma/Waldenstrom macroglobulinemia after one line of therapy.
Drug: Bortezomib-Rituximab-Bendamustine

Bortezomib-Rituximab-Bendamustine Bortezomib: 1.3 mg/mq sc days 1, 8, 15, 22* Rituximab: 375 mg/sqm i.v. day 1** Bendamustine: 90 mg/sqm iv days 1-2 or days 2-3 according to institutional/physician choice Repeat cycles every 28 days for a total of 6 cycles *In case of toxicity is omitted

**In cycles 1, in order to avoid tumor lysis syndrome, Rituximab will be given on day 8

Other Name: BRB

Primary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: 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.

Secondary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: 2 years ]
    Overall response rate (ORR): a patient is defined as a responder if he has a complete or very good partial or partial response, evaluated in based on Waldenstrom macroglobulinemia consensus recommendations of the 6th International Workshop on Waldestrom's macroglobulinemia.

  2. Overall Survival (OS) [ Time Frame: 2 years ]
    Overall survival (OS): measured from the beginning of therapy to the date of death from any cause. Patients alive at the time of the final analysis will be censored at the date of the last contact. Minimum follow up time required for all patients will be 2 years.

  3. Toxicity [ Time Frame: 2 years ]
    Toxicity: severe, life- threatening, fatal (grade 3, 4 and 5)

  4. Number of serious adverse events [ Time Frame: 2 years ]
    Number of serious adverse events are defined according to "Common Terminology Criteria for Adverse Events" (CTCAE), version 4.0
