| To evaluate the anti-lymphoma activity of Bortezomib, Rituximab, Ibrutinib (B-RI) in patients with treatment naïve WM assessing response rates, time to treatment failure, remission duration, cause specific survival and overall survival and to assess the safety of this combination |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
• Clinicopathological diagnosis of WM as defined by consensus panel one of the Second International Workshop on WM, diagnosed by a reference pathology center. In addition, pathological specimens have to be sent to the national pathological reference center at study inclusion. The positivity for CD20 positive can be assumed from any previous bone marrow immunohistochemistry or flow cytometry analysis performed up to 6 months prior to enrollment. Inclusion in the protocol 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 expressions. 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.
• Patients must have at least one of the following critera to initiate treatment as defined by “Consensus Panel Two” recommendations from the Second International Workshop on Waldenström Macroglobulinemia.
- Recurrent fever, night sweats, weight loss, fatigue (at least one of them)
- Hyperviscosity
- Lymphadenopathy which is either symptomatic or bulky (≥ 5cm in maximum diameter)
- Symptomatic hepatomegaly and/or splenomegaly
- Symptomatic organomegaly and/or organ or tissue infiltration
- Peripheral neuropathy due to WM
- Symptomatic cryoglobulinemia
- Cold agglutinin anemia
- IgM related immune hemolytic anemia and/or thrombocytopenia
- Nephropathy related to WM
- Amyloidosis related to WM
- Hemoglobin ≤ 10g/dL
- Platelet count < 100x10^9/L
- Serum monoclonal protein > 5g/dL, even with no overt clinical symptoms
- Low or absent IgG serum levels
• World Health Organization (WHO)/ECOG performance status 0 to 2.
• Other criteria
- Age ≥ 18 years
- Life expectancy > 3 months.
- Baseline platelet count ≥ 100 x 10^9/L (if not due to BM involvement by the lymphoma), independent of any transfusions
- Absolute neutrophil count ≥ 1 x 10^9/L independent of growth factor support. Meet the following pretreatment laboratory criteria at the Screening visit conducted within 28 days of study enrollment:
- ASAT (SGOT): ≤ 3 times the upper limit of institutional laboratory normal value
- ALAT (SGPT): ≤ 3 times the upper limitof institutional laboratory normal value
- Total Bilirubin: < 1.5 times the upper limit of institutional laboratory normal value, unless clearly related to the disease (except if due to Gilbert’s syndrome).
- Serum creatinine: ≤ 2 times the upper limit of institutional laboratory normal value or estimated Glomerular Filtration Rate (Cockroft-Gault) ≥ 40 mL/min/1.73m^2
• Women of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming postmenopausal must agree to use a highly effective method of birth control for the duration of the therapy up to 3 months after end of therapy with Bortezomib and Ibrutinib and up to 12 months after the end of therapy with Rituximab. A highly effective method of birth control is defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal or transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable or implantable), intrauterine device (IUD), intrauterine hormone-releasing system ( IUS), bilateral tubal occlusion, vasectomised partner or sexual abstinence. However, due to Ibrutinib administered in this study, those women using hormonal methods of birth control must add a barrier method. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. Contraception and pregnancy testing are required according the CTFG recommendations (http://www.hma.eu/fileadmin/dateien/Human_Medicines/01-About_HMA/Working_Groups/CTFG/2014_09_HMA_CTFG_Contraception.pdf).
• Men must agree not to father a child for the duration of therapy and 12 months after (use of a condom) and must agree to advice a female partner to use a highly effective method of birth control.
• Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
• Affiliation to a social security scheme (relevant for France only)
