Study Description

Brief Summary:

In Waldenström macroglobulinemia (WM) conventional chemotherapy induces only low CR rates and responses of short duration compared to other indolent lymphomas. Thus innovative approaches are needed which combine excellent activity and tolerability in patients with WM, who are mostly of advanced age. The immunochemotherapy DRC (dexamethasone, rituximab, cyclophosphamide) was shown to be highly effective in patients with WM without inducing major hematological toxicities. On the other hand the proteasome inhibitor Bortezomib showed substantial activity as a single agent in WM with only very few side effects when given in a weekly schedule. Based on these observations it is the aim of this study to test whether the efficacy of the well tolerated DRC regime can be further improved by adding Bortezomib.

Detailed Description:

Waldenström's macroglobulinemia (WM) is defined by a bone marrow infiltration by lymphoplasmacytic cells and the presence of a monoclonal immunoglobulin (Ig) M gammopathy in the peripheral blood. The clinical understanding of the disease has been greatly improved by the identification of internationally recognized criteria for initiating therapy, the description of an international prognostic index for patients requiring a first-line therapy and the definition of response criteria. These criteria are mainly based on the evolution of serum IgM concentration. However, delayed IgM monoclonal protein responses may cause important difficulties in response assessment. In addition, discrepancies between the kinetics of serum M protein reduction and the clearance of monoclonal B-cells from the bone marrow have been reported. Despite continuing advances in the therapy of WM, the disease remains incurable with a median survival of 5 to 8 years from the time of diagnosis thereby necessitating the development and evaluation of novel treatment approaches.

Outcome Measures

Primary Outcome Measures :

1. Progression Free Survival [ Time Frame: participants will be followed for their participation in the trial, an expected average of 5.5 years ]
   PFS will be calculated from the date of inclusion/randomisation to the following events: the date of progression and the date of death if it occurred earlier. In the absence of progression and death, PFS duration will be censored at the stopping date or the date of last follow-up.

Secondary Outcome Measures :

1. Response rate [ Time Frame: 24 weeks ]
   The response rates (CR,VGPR, PR, MR) and overall response rate (CR, VGPR, PR, MR) are evaluated 4 weeks after the end of induction treatment.
2. Best response [ Time Frame: 24 weeks ]
   Best response is determined in the time interval from the start of induction therapy to end of follow-up.
3. Time to best response [ Time Frame: 24 weeks ]
   Time to best response is defined as the time from the start of induction to best response the patient achieves (CR, VGPR, PR, MR).
4. Time to first response [ Time Frame: 24 weeks ]
   Time to first response is defined as the time from the start of induction to first response (MR, PR, VGPR or CR).
5. Time to treatment failure [ Time Frame: participants will be followed for their participation in the trial, an expected average of 5.5 years ]
   Time to treatment failure (TTF) is defined as the time of randomization to discontinuation of therapy for any reason including death from any cause, progression, toxicity or add-on of new anti-cancer therapy. Patients alive without treatment failure are censored at the latest tumor assessment date.
6. Remission duration [ Time Frame: participants will be followed for their participation in the trial (from date of response), an expected average of 5 years ]
   Remission duration will be calculated in patients with response (CR, VGPR, PR, MR) to induction from end of induction to the date of progression, relapse or death from any cause. Patients alive without progression and relapse will be censored at the latest tumor assessment date or the stopping date.
7. Cause specific survival (CSS) [ Time Frame: participants will be followed for their participation in the trial, an expected average of 5.5 years ]
   Cause specific survival is defined as the period from the induction randomization to death from lymphoma or lymphoma related cause; death unrelated to WM is considered as a competing event.
8. Overall survival (OS) [ Time Frame: participants will be followed for their participation in the trial, an expected average of 5.5 years] ]
   Overall survival is defined as the period from the induction randomization to death from any cause. Patients who have not died until the time of the analysis will be censored at their last contact date.

Eligibility Criteria

• Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

Clinicopathological diagnosis of WM as defined by consensus panel one of the Second International Workshop on WM. Pathological diagnosis has to occur before study inclusion and randomization. In addition, pathological specimens have to be sent to the national pathological reference center at study inclusion and randomization. The positivity for CD20 can be assumed from any previous bone marrow immunohistochemistry or flow cytometry analysis performed up to 6 months prior to enrollment. Inclusion in the study will be based on morphological and immunological criteria. Immunophenotyping will be performed in each center and saved locally. Flow cytometry of bone marrow and blood cells will include at least one double staining and assess the expression of the following antigens: surface immunoglobulin, CD19, CD20, CD5, CD10 and CD23. Patients are eligible if tumor cells express the following antigens: CD19, CD20, and if they are negative for CD5, CD10 and CD23 expression. Patients with tumor cells positive for CD5 and/or CD23 and morphologically similar to WM cells may be included after ruling out other low grade B-cell malignancies.
