Study Population 
Previously untreated (except for splenectomy and/or antiviral therapy for HCV 
infection) and symptomatic Splenic Marginal Zone patients. 
 
 
Objectives 
 
Evaluation of the efficacy and the safety of R-Bendamustine in symptomatic 
Splenic Marginal Zone Lymphoma patients. 
 
 
Primary Objective 
 
Efficacy of R-Bendamustine measured by Complete Response rate 
Complete response rate defined as regression to normal size on CT of 
organomegaly (spleen, liver, lymph nodes); normalization of the blood counts 
and no evidence of circulating clonal cells, and no evidence or minor (≤ 5%) BM 
infiltration detected by immunohistochemistry. 
 
* Analysis of minimal residual disease by Flow cytometry and by quantitative Taq Man PCR (RQ-
PCR) targeting clonal IgVH antiCDR3 to evaluate response status and a potential impact on 
progression free survival and long-term remission of patients will be incorporated as research 
evaluation but will be not influence nor the response evaluation nor influence the management of the 
patient.
Secondary Objectives 
 
Efficacy measured by 
· Overall Response Rate (ORR) (Complete response + Partial response) 
· Safety and tolerability measured by toxicities of R-Bendamustine evaluated 

 
IELSG-36 – Version 5.1 – November 22, 2017

by assessment of laboratory parameters and adverse events coded with NCI 
Common Toxicity Criteria, version 4.0 (Appendix F) 
· 3-year Progression Free Survival (PFS), defined as the time from entry into 
the study until reappearance of cytopenia associated with disease 
progression (autoimmune, hypersplenism) or lymphoma relapse/progression 
with enlarged lymph node(s) or spleen if present, histologic transformation or 
death as a result of any cause 
· Duration Of Response (DOR), is defined for all patients who achieved a 
response (CR and PR) and is measured from the time of response until the 
date of first documentation of progression or relapse. 
· 3-year Event Free Survival (EFS), measured from the time from study entry 
until appearance of any of the following event: any treatment failure 
including disease progression/relapse, or initiation of new anti-lymphoma 
therapy or death 
· Time to Next Treatment (TTNT), defined as the time from the end of the 
chemo-immunotherapy course to the day of next treatment commencement 
irrespective of cause 
· 3-year Overall Survival (OS), defined as the time from date of treatment start 
into the study until the date of death irrespective of cause. Patients who have 
not died at the time of end of the whole study, and patients who are lost to 
follow up, will be censored at the date of the last contact 
· Risk of histological transformation 
· 5 year-PFS and - OS

Or days 2-3 according to institutional/patient/physician preference 
§ 
Administration of Rituximab during cycle 1 and 2 can be postponed to day 8 or 14 in case of 
risk of tumor lysis syndrome e.g. marked splenomegaly or lymphocytosis above 10.000 
lymphocytes/mm3 
 
The use of G-CSF for prophylaxis is recommended according to EORTC 
guidelines (appendix O); either filgrastim, lenograstim or peg-filgrastim can be 
used. It is recommended to prescribe anti-infectious agents for all patients with 
valaciclovir 500 mg/d and trimetroprim/cotrimoxazole 400mg/d during all the 
chemotherapy. 
 
A centralized PET scan evaluation will be performed; the anonymized PET scan 
images will be collected and preserved for the entire duration of the study at 
the LYSARC (Resp. Romain Ricci, Coordinator Imaging LYSARC, CHU Henri 
Mondor Créteil, Service de Médecine Nucléaire). The images will be evaluated 
by a group of expert nuclear medicine (Dr. Salim Kanoun, Service de Medecine 
Nucleaire  IUCT-ONCOPoLE, Institut C. Regaud, Toulouse, France and Dr. Michel 
Meignan, LYSA Imaging, Hopitaux Universitaires Henri Mondor, Créteil, France)

to analyze the clinical response of the patients. 
 
 
 
 
Response Criteria (according to Matutes et al, Leukemia 2008) 
·
Complete Response (CR) all the following criteria must be fulfilled: 
1. Resolution of organomegaly 
2. Normalization of the blood counts (Hb >12 g/dL; Plt >100.000/mm3;

clonal B-cells- 
3. No evidence of BM infiltration  
 
·
Partial Response (PR) 
≥ 50% improvement in the disease manifestations that should include: 
1. Resolution or decrease in spleen size. 
2. Improvement on cytopenias. 
3. Resolution or decrease in lymphoadenopathy if present. 
4. BM should show a decrease in the level of lymphoid infiltration and 
improvement of the haematopoietic reserve. 
 
·
No response (NR) and progressive disease (PD) 
1. Less than 10% improvement on the disease manifestations or 
deterioration by increase >50% of measurable signs of the disease from 
nadir, respectively.

INTRODUCTION AND STUDY RATIONALE 
 
 
1.1 
Disease Background: Splenic Marginal Zone Lymphoma 
 
Splenic Marginal Zone Lymphoma (SMZL) is a well defined low-grade B-cell lymphoma, ranking as a 
distinct entity in the WHO (World Health Organization) classification1. Although it is considered as a rare 
neoplasm accounting for about 2% of all non Hodgkin’s lymphomas (NHL) it is estimated represents for 
most cases of otherwise unclassifiable chronic lymphoid B-cell CD5-lymphoprolipherative disorders2.  
The peak of incidence is in the sixth decade with an almost equal female/male ratio.  SMZL is 
characterized by an almost exclusive involvement of the spleen and bone marrow3-5. Peripheral blood 
involvement is usually scanty and in about half of cases the circulating neoplastic lymphocytes display a 
characteristic villous appearance. Signs and symptoms are mostly related to the development of 
peripheral cytopenias and or to the abdominal discomfort associated with the presence of a huge 
splenomegaly5-11. The definite diagnosis rely on spleen histology which is considered the gold standard 
diagnostic assay1,12. Recently, to avoid a major surgical procedure for mere diagnostic purposes in 
otherwise healthy subjects, the Splenic Lymphoma Group proposed guidelines for the diagnosis of 
SMZL based on the merging of bone marrow and peripheral blood picture with immunophenotypic and 
cytogenetic data13,14 (Appendix D). SMZL affects the elderly with a median age of 70 years, the median 
survival exceeds ten years and most patients can be effectively managed for many years with a 
watchful waiting policy. Yet in about 25% of cases the disease pursues an aggressive course and most 
patients die of lymphoma progression within 3-4 years. Some presenting features on diagnosis have 
been shown to have a significant prognostic value (extranodal involvement; high lymphocyte count; 
anemia; lymphonode involvement; thrombocytopenia) and when they develop during the course of the 
disease are harbinger of disease progression6-8,11. The Intergruppo Italiano Linfomi (IIL) have proposed a 
clinical score based on three parameters15: anemia, elevated LDH values and hypoalbuminemia 
(Appendix G). Patients showing two or more of the above adverse prognostic factors have a median life 
expectancy of less than five years. For the time being, there is not a prospectively validated therapy for 
SMZL and splenectomy has been deemed to be the therapeutic approach most effective in patients 
complaining signs and symptoms secondary to hyperpslenism. However, though almost all patients 
achieve a clinical response after splenectomy they eventually relapse or progress. Moreover, most of 
SMZL patients are elderly and show comorbities that classify them as poor surgical risk16-18. For these 
patient or those who show a spread of the disease to lymphonodes or other extranodal sites or others 
adverse prognostic factors, a systemic treatment may be appropriate. Retrospective studies have 
indicated that alkylating-agents monotherapy do not produce any clinical benefit while purine analogs 
(i.e. fludarabine, cladribine, and pentostatine) achieved very high response rates in both naïve and pre-
treated patients19-21. Moreover, the introduction of the anti-CD20 humanized antibody rituximab, either 
used alone or in combination with chemotherapy has been reported to be very effective in producing a 
rapid clearance of neoplastic cells. Treatment of such patients with rituximab both alone or in 
combination with chemotherapy has shown remarkable responses22-30.  
In 2005 the IIL started a prospective phase II trial to verify the efficacy of rituximab in combination with 
COMP (Cyclophosphamide, Oncovin, Myocet, Prednisone) chemotherapy, as front-line therapy for 
SMZL patients, in terms of response, survival, and safety. To be included in the trial, patients should had 
a diagnosis of SMZL supported by spleen histology or by a combination of bone marrow and peripheral 
blood morphologic and immunophenotipic data; patients should also be untreated for lymphoma and 
have active disease defined by the presence of at least one of the following: Hb <10g/dl; plt

<100.000/mmc, symptomatic splenomegaly, elevated LDH, B symptoms, extrasplenic disease, LDT <12 
months. The preliminary results of this study have been presented at 2007 ASH meeting31. The most 
important findings were an ORR of 100% with 63% of CR. The results have been recently update, 
confirming on 63 patients an 85% ORR with 63% CR rate, and a 82% PFS at three years. However, the 
toxicity profile showed a 24% haematological toxicity WHO 3-4 and one patients died of therapy-related 
cardiac failure while in CR.  
1.2 
Drug background 
 
1.2.1 
Bendamustine 
 
Bendamustine was synthesized in 1963 in what was then the German Democratic Republic32. There, it 
was widely used, but not widely studied. When the Iron Curtain fell and the Federal Republic of 
Germany was reunited, investigators began to study bendamustine’s mechanism of action and its 
clinical activity. Although the early studies were plagued with problems, clear evidence of activity 
against low-grade lymphoproliferative disorders previously treated with other alkylating agents began 
to emerge, largely in the absence of significant toxicity33-38. More recently, several large, well designed 
and well-conducted trials39-41 have provided intriguing data that not only have allowed investigators 
outside of Germany to consider the potential role of bendamustine in the treatment of 
lymphoproliferative disorders in the future, but have also led the Food and Drug Adminstration (FDA) of 
the United States to approve bendamustine for the treatment of CLL and indolent B-cell non-Hodgkin 
lymphoma (NHL), thus providing clinicians a “new” treatment option for their patients right now42.  
 
Bendamustine Clinical Pharmacology 
 
Mechanism of Action 
The bendamustine molecule is composed of 3 structural elements: a mechlorethamine (nitrogen 
mustard) group, a benzimidazole ring, and a butyric acid side chain42. The mechlorethamine (nitrogen 
mustard) group is similar to other alkylators like cyclophosphamide and chlorambucil. The 
benzimidazole ring, which replaces the benzene ring present in chlorambucil, is unique and is similar in 
structure to some purine analogs such as 2-chlorodeoxyadenosine. This observation has led some to 
hypothesize that bendamustine may have purine analog activity as well, but no evidence for 
antimetabolite functionality has been confirmed. Although an alkylator itself, bendamustine displays 
distinct preclinical activity. DNA breaks induced by bendamustine are significantly greater in number 
than those produced by cyclophosphamide or carmustine and are more durable than those associated 
with melphalan, cyclophosphamide, or carmustine34,43. This extensive DNA damage leads to inefficient 
DNA repair mechanisms, resulting in inhibition of checkpoint control. The resultant cell cycle changes 
culminate in mitotic catastrophe, another pathway leading to cell death44. Furthermore, bendamustine 
activates a base-excision DNA-repair pathway, rather than an alkyltransferase DNA repair mechanism 
like other alkylating agents. This observation suggests that bendamustine may be less susceptible to 
alkylguanyl transferase expression–based drug resistance45.  
 
Bendamustine Pharmacokinetic Parameters And Drug Metabolism 
 
Absorption 
Not applicable, since bendamustine is administered by intravenous route. 
 
Distribution 
Bendamustine undergoes first-pass metabolism, primarily in the liver by the action of cytocrome p450 
enzyme complex. Bendamustine is highly protein bound (> 95%), primarily to albumin. Protein binding 
is not affected by advanced age, low serum albumin levels or presence of advanced tumor. However, 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
9 
only free, unbound bendamustine is active. After intravenous administration of bendamustine volume 
of distribution at steady state is 19,8 L. 
 
Metabolism and Excretion 
Elimination of bendamustine is rapid and occurs predominantly by the renal route, with peak 
metabolite concentrations found in the urine one hour after administration; only a small amount of the 
drug is eliminated by the liver. Mean total clearance was reported to be 49.6 L/h and to be independent 
of dosage over the range 0.5 to 5 mg/kg. Elimination is biphasic with a half-life (t1/2α) of 6 to 10 
minutes, and a termination half-life (t1/2β) of approximately 30 minutes. Bendamustine is eliminated 
primary by renal route and therefore should not be given to patients in whom renal function is 
compromised (glomerular filtration rate <10ml/min). Bendamustine is also contraindicated in patients 
with severe hepatic damage, since primary metabolism occurs in the liver. There are at present no 
published data on placental transfer or excretion in breast milk of bendamustine. 
 
Bendamustine Preclinical And Clinical Data 
 
Preclinical studies demonstrate bendamustine’s activity in cancer cells that are resistant to other 
alkylating agents. Alkylator-resistant human B-CLL cells are less resistant to bendamustine46 and there is 
clinical evidence that bendamustine retains activity when other alkylators fail47,48. The overall remission 
rate was 56%, with a median duration of remission of 42.7 months. Several studies of bendamustine-
based therapy in patients with relapsed and refractory low-grade lymphomas report overall remission 
rates from 48% to 97%34,42-45. Thus, both preclinical and clinical data suggest that bendamustine may 
have properties distinct from other alkylating agents. These observations informed the design of larger 
studies that extend these preliminary observations. 
 
Several experiences have been published related to the use of bendamustine as a single or combined 
agent in low-grade lymphomas. As a single agent, bendamustine was administered to 52 evaluable 
patients with relapsed or refractory low-grade lymphomas at a dose of 120 mg/m2 on the first 2 days of 
a 21-day cycle49. The median age of the patients was 63 years (range, 36-82 years), and all patients had 
been previously exposed to alkylating agents. The overall response rate (ORR) was 73%, and 11% 
achieved complete remission (CR). The regimen appeared to be remarkably well tolerated, and only 3 
patients developed grade 3 or 4 toxicity, both grade 3 neutropenia. This study and similar studies 
conducted in Europe suggest activity of bendamustine against low grade lymphoma in the absence of 
debilitating or unmanageable toxicity39. To help confirm these preliminary observations, a North 
American study was organized to test the safety and efficacy of bendamustine in rituximab refractory 
patients with indolent and transformed non-Hodgkin lymphoma. Patients enrolled on this study were 
defined as rituximab-refractory if they failed to respond or progressed within 6 months of previous 
treatment with rituximab. This multicenter trial enrolled 77 patients, and 76 patients were treated with 
bendamustine 120 mg/m2 on the first 2 consecutive days of a 21-day cycle. Nineteen patients required 
dose reductions. The incidence of grade 3-4 neutropenia was 54% and of grade 3-4 thrombocytopenia 
was 25%. Non-hematologic toxicities were common, but generally mild with grade 1-2 nausea in 68% 
and grade 1-2 fatigue in 42%. No patient developed alopecia or mucositis. Although these patients were 
frequently relapsed from combination chemotherapy regimens, and 20% had transformed disease, the 
ORR was 77%, and 34% achieved CR.41 Interestingly, the ORR in patients with alkylator-resistant 
disease was 61%, and it was 62% in the 8 patients with fludarabine-refractory disease. For all patients, 
the median progression-free survival (PFS) was 7.1 months. The results of the study performed by 
Friedberg et al confirm earlier findings and clearly establish bendamustine as a safe and effective 
treatment for relapsed and refractory low-grade lymphomas. Although remission rates were high, 
however, the duration of remission was relatively short. Thus, bendamustine has been combined with 
other active agents to determine whether results could be improved. Although its efficacy and safety 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
10 
profile in the treatment of low-grade lymphoma would have been enough to consider rituximab in 
combination with bendamustine, preclinical studies also suggest a degree of synergism with the 
combination against lymphoma cell lines and in severe combined immunodeficient mice with Daudi 
xenografts50. Therefore, rituximab has been combined with bendamustine (BR) for the treatment of 
low-grade lymphoma in some recent clinical trials. A study from Germany accrued 63 patients with 
relapsed or refractory low-grade non-Hodgkin lymphoma for treatment with BR. Rituximab 375 mg/m2 
was administered on Day 1, and bendamustine was administered at a dose of 90 mg/m2 on Days 2 and 
3 of a 28-day treatment cycle37. Rituximab was also infused 1 week before the first treatment cycle and 
4 weeks after the fourth and final treatment cycle. The median age of the patients was 64 years (range, 
40 to 81 years). The beta-2 microglobulin level was >2 mg/dL in 48%, and the lactate dehydrogenase 
level was >240 U/L in 24% of assessable patients. Toxicity was graded according to World Health 
Organization (WHO) guidelines and was largely limited to myelosuppression (16% grade 3-4 leukopenia) 
and nausea (102 of 136 treatment cycles complicated by grade 1 nausea). Hematopoietic growth 
factors were allowed on the study, but none was used. The ORR rate to BR on this study was 90%, and 
60% achieved a CR. Patients with relapsed mantle cell lymphoma had an ORR of 75%, and 50% achieved 
CR. These remissions were also reasonably durable, with a median progression-free survival of 24 
months. The median PFS in patients with mantle cell lymphoma was 18 months. The remarkable results 
of the German study of BR prompted a confirmatory study in North America. The treatment regimen 
was identical to the German study, but toxicity was graded according to the National Cancer Institute’s 
Common Terminology Criteria (NCI-CTC). Sixty-seven patients with relapsed or refractory low-grade 
non-Hodgkin lymphoma were enrolled in this trial, and 66 patients were treated with BR41. This 
population of patients had a median age of 60 years (range, 40-84 years) and was similar to the German 
cohort. The efficacy results of the North American Trial were also very similar to those of the German 
trial. Both studies demonstrate excellent activity against low-grade lymphomas across multiple 
histologic subtypes. The 2 studies differed in their assessment and reporting of toxicity, leading to 
apparent discrepancies in their respective toxicity results. In the German study, toxicity was reported as 
a function of events per treatment cycle, whereas in the North American study toxicity was reported as 
a function of study participants. Grade 3-4 leukopenia was reported in 16% of treatment cycles in the 
former study, and in 30% of study participants in the latter study. The discrepancy is more than just in 
the way toxicity was reported. Therefore, the toxicity in the 2 trials is not as easily compared as the 
response rates are. Nonetheless, severe adverse events were uncommon in both studies. 
 
Considering this treatment option bendamustine is neither a new drug, nor a biologically targeted 
agent. Yet it has unique activity against lymphoproliferative disorders, and its favorable side-effect 
profile makes it amenable for use in combination with other agents. 
 
 
1.2.2 
Rituximab  
 
Rituximab is a mouse/human chimaeric IgG1-k monoclonal antibody that targets the CD20 antigen 
found on the surface of malignant and normal B lymphocytes.18 
Although not fully elucidated, the cytotoxic effects of rituximab on CD20-positive malignant B cells 
appears to involve complement-dependent cytotoxicity, antibody-dependent cellular cytotoxicity and 
induction of apoptosis.19-20 
Rituximab has demonstrated efficacy in patients with various lymphoid malignancies, including indolent 
and aggressive forms of B-cell NHL and B-cell chronic lymphocytic leukaemia (CLL).21-27 However few are 
the data on the use of rituximab alone or in combination in patients with Splenic Marginal Zone 
Lymphoma. Since approval of rituximab, treatment of such patients with rituximab both alone or in 
combination with chemotherapy has shown remarkable responses. In literature six retrospective 
studies adding up 52 patients are reported. The overall response rate both in refractory/relapsed and 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
11 
treatment naive cases was rather high ranging from 88% to 100%. Worth noting the prompt and 
marked shrinkage of splenomegaly and the amelioration of the peripheral cytopenias, mostly registered 
within the third course of therapy. Treatment with rituximab is generally well tolerated, particularly in 
terms of adverse haematological effects and serious or opportunistic infections relative to standard 
chemotherapy.

contains no antimicrobial preservative. The admixture should be prepared as close as possible to the 
time of patient administration. After reconstitution and dilution the chemical stability has been proved 
during 3,5 hours at temperature of 25°C and during 2 days in a range of temperature between 2°C and 
8°C in polyethylene bags. Administration of bendamustine must be completed within this period. 
Bendamustine solution should be prepared and handled according to the instructions provided in 
Appendix L. 
Rituximab: for rituximab admixture preparation and handling please refer to the Standard Medical 
Practice. 
 
 
4.3 
Drug Supply and storage 
 
As rituximab will be administrated according to the marketing authorization, it will not be supplied by 
the sponsor and will be provided by the local pharmacies.  
Bendamustine will be supplied by Mundipharma. 
At the study site, all investigational study drugs will be stored in a locked, safe area to prevent 
unauthorized access. The study drug should be stored at room temperature away from direct sunlight 
and protected from excessive heat and cold. 
 
Packs of bendamustine vials shouldn’t be stored at above 25°C.

Patients will be treated with 3 courses of R-Bendamustine and then restaged. If in PR patients will 
proceed to the next extended phase with 3 more R-B courses. If in CR only one more R-Bendamustine 
course will be delivered. Patients with clinical response less than PR will go off the study. Patients in CR 
or PR at the end of the third course of R-Bendamustine and who proceeded to the extended phase will 
be considered to have completed the chemio-immunotherapy program and will undergo final restaging 
after 4 courses or after 6 courses (24 weeks) of R-Bendamustine treatment patients respectively.

INDUCTION PHASE 
 
EXTENDED PHASE 
 
 
A centralized PET scan evaluation will be performed; the anonymized PET scan images will be collected 
and preserved for the entire duration of the study at the LYSARC (Resp. Romain Ricci). The images will 
be evaluated by a group of expert nuclear medicine to analyze the clinical response of the patients (See 
APPENDIX Q). 
 
 
4.6 
Dose modification or interruption 
At the end of each course of R-B patients will be evaluated for possible toxicities that may have 
occurred during the cycle. Toxicities are to be assessed according to the National Cancer Institute 
Common Toxicity Criteria for Adverse Events (NCI CTCAE), Version 4.0 (see Appendix J). 
 
4.6.1 
Bendamustine dose modification 
 
Patients will start R-B every 28 days. Bendamustine administration should be delayed (after 7 days, on 
Day +35 of each cycle) in the event of Grade 4 hematologic toxicity or clinically significant ≥ Grade 2 
non-hematologic toxicity. 
For patients started on treatment with neutropenia or thrombocytopenia due to hypersplenism or to 
SMZL bone marrow infiltration (see section inclusion criteria 3.2.1) the R-B will be delivered every 28 
days if neutrophils and platelet values match those at pre-treatment. If neutrophils and platelet values 
are lower than those at pre-treatment, R-B must be delayed (after 7days, on Day +35 of each cycle). 
In case of neutropenia (<1.000/mm3) at day +28, even if it is consequence of bone marrow infiltration 
and/or hypersplenism, subsequent cycles will be administered with G-CSF or PegGCSF support (see 
section 4.7.2). 
Once non-hematologic toxicity has recovered to ≤ Grade 1 and/or the blood counts have improved 
[Absolute Neutrophil Count (ANC) ≥1.000/mm3, platelets ≥75.000/mm3], Bendamustine can be 
reinitiated at the discretion of the treating physician. In addition, dose reduction may be warranted. 
 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
17 
Dosing will be delayed up to 4 weeks until the criteria for reinitiating therapy are met. Patients who did 
not meet these criteria after a 4-week delay will be removed from protocol therapy. 
 
4.6.2 
Rituximab dose modification 
 
Rituximab administration and dose modification must follow labeling instructions and guidelines. Please 
refer to the approved product label for instructions. 
Patients who develop severe infusion reactions should have rituximab infusion discontinued and 
supportive care measures as medically indicated (e.g. fluids, vasopressors, oxygen, bronchodilators, 
paracetamol, etc.). In most cases, the infusion can be resumed at 50% reduction rate (e.g. from 100 
mg/hr to 50 mg/hr) when symptoms have completely resolved. Patients requiring close monitoring 
during first and all subsequent infusions include those pre-existing cardiac and pulmonary conditions, 
those with prior clinically significant cardiopulmonary adverse events, and whose with high numbers of 
circulating malignant cells (>25 x 109/l) with or without evidence of high tumor burden. 
 
 
4.7 
Concomitant Treatment 
 
4.7.1 
Recommended concomitant therapy 
 
During treatment are recommended as concomitant therapy: 
Patients will receive prophylactic treatment with valciclovir 500 mg/d and trimetroprim/Cotrimoxazole 
double strengths (one tablet twice daily, given three times per week, Monday, Tuesday, Wednesday) 
untill the completion of the last Rituximab-Bendamustine cycle. 
If cutaneous toxicity appears, an amendment will be written in order to give Bactrim only in patients 
with low level of CD4. 
In patients HBcAb+, prophylaxis against hepatitis B reactivation with Lamivudine 100 mg/die from the 
start of the treatment to one year after the end of the treatment. 
All concomitant medications for medical conditions other than B-NHL are permitted, as clinically 
Indicated. 
All supportive therapies other than anti-cancer treatment needed for the management of patients 
enrolled in this study are permitted. 
 
4.7.2 
Permitted concomitant therapy 
 
The following medications and support therapies that may be used if needed during this study: 
Prophylaxis with levofloxacine or ciprofloxacine and fluconazole/itraconazole will be administrated in 
case of neutropenia <1.000/mm3. Platelets and red blood cell transfusion are allowed, if needed, and 
will be given in case of Hb <8 g/dl or Plt <10.000/mm3. 
Erytropoietin therapy is allowed according to ASH/ASCO guidelines. G-CSF or PegG-CSF Is allowed and 
will be given according to primary physician decision. 
Immunoglobulin assay is advisable during induction therapy and follow-up; immunoglobulin 
replacement therapy is advisable in case of IgG level <0.3-0.5 gr/dl and frequent infectious events. 
Premedication for rituximab infusion with paracetamol and diphenhydramine should be considered 
before each infusion of rituximab, because it may reduce infusion reactions. 
 
4.7.3 
Prohibited concomitant therapy 
 
The following medications and supportive therapies are prohibited at all times: 
·
Any antineoplastic agent other than those planned by the study program;

EFFICACY MEASUREMENT AND PARAMETERS 
 
 
7.1 
Efficacy measurement 
 
Patients receiving at least 2 courses of R-BENDA will be considered the Efficacy Population (EP). 
 
 
7.2 
Efficacy parameters 
 
7.2.1 
Primary endpoints 
 
Efficacy of R-Bendamustine measured by Complete Response rate. 
Complete response rate will be assessed by means of CT-scan, Immunophenotype in blood and bone 
marrow (PET-scan optional). 
 
The recently published recommendations of an International experts panel13 will be applied. Response 
criteria will be determined as follows: 
Complete response (CR) requires the disappearance of all evidence of disease 
a. Regression to normal size on CT of organomegaly (splenomegaly, hepatomegaly and 
lymphoadenopathies) 
b. Normalization of the blood counts (Hb >12 g/dl; platelets >100.000/mm3; neutrophils >1.500/mm3 
and no evidence of circulating clonal B-cells) 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
27 
c. No evidence or minor (<5%) BM infiltration detected by immunohistochemistry.  
Partial response (PR) requires regression of 50% or greater in the measurable disease manifestations 
and no new sites of disease. This should include: resolution or decrease in spleen size, improvement on 
cytopenias and resolution or decrease in lymphadenopathy if present. Bone Marrow should show a 
decrease in the level of lymphoid infiltration and improvement of the haemopoietic reserve. 
No response (NR) and progressive disease (PD) less than 10% improvement on the disease 
manifestations or deterioration, by increase >50%, of measurable signs of the disease from nadir- 
Relapsed disease: Reappearance of any measurable sign of the disease. 
A patient is defined as a responder if she/he has a complete or partial response. Patients without 
response assessment (due to whatever reason) will be considered as non-responders. 
 
7.2.2 
Secondary endpoints 
 
v Overall Response Rate (ORR) (Complete response + Partial response) 
v Safety and tolerability measured by toxicities of R-Bendamustine evaluated by assessment of 
laboratory parameters and adverse events coded with NCI Common Toxicity Criteria, version 4.0 
(Appendix J). 
v 3-year Progression Free Survival (PFS), defined as the time from entry into the study until 
reappearance of cytopenia or lymphoma relapse/ progression with enlarged lymph node(s) or 
spleen if present, histologic transformation or death as a result of any cause. Responding patients, 
patients who are lost to follow up, who withdrawal the consent or drop-out due to adverse event 
will be censored at their last assessment date. Patients died due to tumor will be considered in 
progression. Patients died for any other cause will be censored to the death date. 
v Duration of Response (DR), is defined for all patients who achieved a response (CR and PR) and is 
measured from the time of response until the date of first documentation of progression or relapse. 
Patients without relapse or progression will be censored at their last assessment date. Patients died 
due to tumor will be considered in progression. Patients died for any other cause will be censored to 
the death date. 
v 3-year Event Free Survival (EFS), will be measured from the day of treatment start to the date of 
documentation of one of the following events: any treatment failure including disease progression, 
or discontinuation of treatment for any reason (eg, disease progression, toxicity, patient preference, 
initiation of new treatment without documented progression, or death). Responding patients, 
patients who are lost to follow up, who withdrawal the consent or drop-out due to adverse event 
will be censored at their last assessment date. 
v Time To Next Treatment (TTNT), defined as the time from the end of the chemo-immunotherapy 
course to the day of next treatment commencement irrespective of cause 
v 3-year Overall Survival (OS), defined as the time from the date of treatment start into the study 
until the date of death irrespective of cause. Patients who have not died at the time of end of the 
whole study, and patients who are lost to follow up, will be censored at the date of the last contact 
v Risk of histological transformation 
v 5-year -PFS and -OS 
 
The overall response rate and the rate of the single response type (CR and PR) will be estimated with 
the 95% confidence interval. 
Time to event data (PFS, DR, TTNT, OS) will be estimated using the Kaplan-Meier method. 
The curves will be plotted and the 95% confidence interval for median time will be calculated.

SAFETY MEASUREMENT AND PARAMETERS 
 
 
8.1 
Safety measurements 
 
All patients who have received at least one dose of study medication will be considered the Safety 
Population (SP) and will be evaluated for toxicity from the time of their first drug administration. When 
toxicity occurs, it should be graded according to the NCI Common Toxicity Criteria, version 4.0 
(Appendix J). 
Any clinically significant abnormalities persisting at the end of the study will be followed by the 
investigator until resolution or until reaching a clinically stable endpoint. 
The study will include the evaluations of safety and tolerability as described in the following sections.  
 
 
8.2 
Safety parameters 
 
8.2.1 
Adverse Events (AE) 
 
Adverse events will be reported by the subject (or, when appropriate, by a caregiver, surrogate, or the 
subject’s legally acceptable representative) for the duration of the study. 
Clinical Laboratory Tests 
All laboratory tests should be performed at the laboratory of the investigational site or other certificate 
laboratories according to physician decision. 
Any clinically significant abnormalities persisting at the end of the study will be followed by the 
investigator until resolution or until reaching a clinically stable endpoint. 
 
8.2.1.1 Adverse Event reporting 
 
Timely, accurate, and complete reporting and analysis of safety information from clinical studies are 
crucial for the protection of subjects and are mandated by regulatory agencies worldwide. 
 
8.2.1.2 Definition of Adverse Event 
 
An adverse event (AE) is any noxious, unintended, or untoward medical occurrence occurring at any 
dose that may appear or worsen in a subject during the course of a study. It may be a new intercurrent 
illness, a worsening concomitant illness, an injury, or any concomitant impairment of the subject’s 
health, including laboratory test values (as specified by the criteria below), regardless of etiology. Any 
medical condition that was present prior to study treatment and that remains unchanged or improved 
should not be recorded as an AE. If there is a worsening of that medical condition this should be 
considered an AE. A diagnosis or syndrome should be recorded on the AE page of the Case Report Form 
rather than the individual signs or symptoms of the diagnosis or syndrome. 
All AEs will be recorded by the Investigator(s) from the time of signing the informed consent through 
the end of the designated follow-up period. 
 
8.2.1.3 Abnormal laboratory values defined as Adverse Events 
 
An abnormal laboratory value is considered to be an AE if the laboratory abnormality is characterized 
by any of the following: 
·
Results in discontinuation from the study. 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
29 
·
Requires treatment, modification/interruption of study drug dose, or any other therapeutic 
intervention. 
·
Is judged by the Investigator(s) to be of significant clinical importance. 
If a laboratory abnormality is one component of a diagnosis or syndrome, then only the diagnosis or 
syndrome should be recorded on the AE page of the CRF. If the abnormality was not a part of a 
diagnosis or syndrome, then the laboratory abnormality should be recorded as the AE. 
 
8.2.2 
Serious Adverse Events (SAE) 
 
A serious adverse event (SAE) is any AE which: 
·
Results in death 
·
Is life-threatening (i.e., in the opinion of the Investigator(s) the subject is at immediate risk of death 
from the AE) 
·
Requires inpatient hospitalization or prolongation of existing hospitalization 
·
Results in persistent or significant disability/incapacity (a substantial disruption of the subject’s 
ability to conduct normal life functions) 
·
Is a congenital anomaly/birth defect 
·
Constitutes an important medical event: important medical events are defined as those occurrences 
that may not be immediately life threatening or result in death, hospitalization, or disability, but may 
jeopardize the subject or require medical or surgical intervention to prevent one of the other 
outcomes listed above. Medical and scientific judgment should be exercised in deciding whether 
such an AE should be considered serious. 
Events not considered to be SAEs are hospitalizations which: were planned before entry into the clinical 
study; are for elective treatment of a condition unrelated to the studied indication or its treatment; 
occur on an emergency outpatient basis and do not result in admission (unless fulfilling other criteria 
above); are part of the normal treatment or monitoring of the studied indication and are not associated 
with any deterioration in condition. 
If an AE is considered serious, both the AE pages of the CRF and the SAE Report Form must be 
completed. 
For each SAE, the Investigator(s) will provide information on severity, start and stop dates, relationship 
to study drug, action taken regarding study drug, and outcome. 
 
8.2.2.1 SAE reporting to Regulatory Authorities and Ethic Committees  
 
The pharmacovigilance team (see section 8.6) will inform relevant Regulatory Authorities and the Ethics 
Committee: 
a) of all relevant information about serious unexpected adverse events suspected to be related to the 
study medication that are fatal or life threatening as soon as possible, and in any case no later than 
seven days after knowledge of such a case. Relevant follow-up information for these cases will 
subsequently be submitted within an additional eight days. 
b) of all other serious unexpected events suspected to be related to the study medication as soon as 
possible, but within a maximum of fifteen days of first knowledge by the investigator(s). 
 
 
8.3 
Classification of severity 
 
For both AEs and SAEs, the investigator(s) must assess the severity of the event. The severity of adverse 
events (AEs) will be graded on a scale of 1 to 5 according to the National Cancer Institute (NCI) Common 
Terminology Criteria for Adverse Events Version 4.0 (NCI CTCAE). The NCI CTCAE V4.0 can be viewed on-
line at the following NCI web site (http://ctep.cancer.gov/reporting/ctc.html). 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
30 
If a specific event is not included in the NCI CTCAE toxicity scale, the following scale should be used to 
grade the event: 
1. Mild: Awareness of sign, symptom, or event, usually transient, requiring no special treatment and 
generally not interfering with usual daily activities. 
2. Moderate: Discomfort that causes interference with usual activities; usually ameliorated by basic 
therapeutic maneuvers. 
3. Severe: Incapacitating with inability to do usual activities or significantly affects clinical status and 
warrants intervention. Hospitalization may or may not be required. 
4. Life-threatening: Immediate risk of death; requires hospitalization and clinical intervention. 
5. Death. 
 
 
8.4 
Classification of relationship/causality of Adverse Events (SAE/AE) to 
study drug(s) 
 
The Investigator(s) must determine the relationship between the administration of study drug and the 
occurrence of an AE/SAE as Not Suspected or Suspected as defined below: 
v Not suspected: The temporal relationship of the adverse event to study drug administration makes a 
causal relationship unlikely or remote, or other medications, therapeutic interventions, or 
underlying conditions provide a sufficient explanation for the observed event. 
v Suspected: The temporal relationship of the adverse event to study drug administration makes a 
causal relationship possible, and other medications, therapeutic interventions, or underlying 
conditions do not provide a sufficient explanation for the observed event. 
 
 
8.5 
Monitoring of Adverse Event and period of observation 
 
Adverse events, both serious and non–serious, and death that occur during the patient’s study 
participation will be recorded in the source documents. All SAEs should be monitored until they are 
resolved or are clearly determined to be due to a patient’s stable or chronic condition or intercurrent 
illness(es).

STATISTICAL METHODS 
 
 
The primary objective of the study is to demonstrate a clinical benefit in Complete remission Rate (CR) 
with Rituximab-Bendamustine association in patients with splenic marginal zone lymphoma and splenic 
lymphoma. Complete Remission was used to determine the sample size of the study. 
There are no established data in splenic marginal zone lymphoma patients in first line treatment. The 
CR rate with rituximab and different chemotherapy regimens in previous studies ranged from 40 to 
80%. Comparison data for the study design and sample size calculations come from a median of those 
reported from different studies. The median expected CR rate for splenic marginal zone with the same 
characteristics indicated into the study and treated with standard rituximab + chemotherapy may be 
estimated to be approximately 60%. We would consider a positive result to increase CR rate from 60% 
to 80%. 
This phase II study has been designed according to Simon’s two-stage Optimal Design, since it is the 
design that minimizes the expected sample size given a 'bad' response rate. 
 
 
9.1 
Parameter specifications and sample size calculation 
 
Parameters 
v Standard proportion of CRR: p0 (null hypothesis) = 0.6 
v Minimum required CRR for the new regimen: p1 (alternative hypothesis) = 0.80 
v Alpha error (two sided) = 0.05 
v Beta error (power) = 0.9 
 
Sample size 
v Potential recruitment = thirty-four patients/year 
v # Valuable patients required = 53 
v Drop out 10% 
v Refused after central histological review 10% 
v 65 subjects (total) 
v Estimated study duration 7 years 
 
 
9.2 
Analysis plan 
 
9.2.1 Analysis populations 
The Safety Population consists of all enrolled patients who received at least one dose of study agent. 
The Efficacy Population consists of enrolled patients who completed at least two cycles of treatment. 
Number per protocol sample is defined. 
 
9.2.2 Interim analysis 
An interim analysis will be performed after recruitment of the first 19 valuable patients. Aim of this 
analysis is to determine preliminary the activity of the treatment. 
 
9.2.3 Parameters of efficacy 
The analysis of efficacy parameter will be performed according to the Intent to Treat principle. 
 
9.2.4 Assessment of safety 
Safety analysis will be based on all enrolled patients who received at least one dose of study agent. 
Adverse events, including toxicities, will be analyzed calculating the number and percentage of patients 
with event.

APPENDIX A - Guidelines for diagnosis review  
 
In order to assure the high quality and consistent pathology diagnosis, a centralized diagnosis review is 
included in this trial, to be performed during the Screening phase of the study, i.e. before therapy start. 
Paraffine embedded tissue block, bone marrow trephine biopsy, peripheral blood smears/bone marrow 
aspirate, flow-cytometry results on peripheral blood and marrow will be centrally reviewed separately 
for LYSA and FIL centers. 
For timeline of review processes refer to group specific guidelines detailed in Appendix M. 
 
Diagnosis will be established according to WHO classification for splenectomized cases1 and according 
to the Splenic Lymphoma Group recommendations for non splenectomized cases13, with full support of 
immunohistochemistry.  
 
Where indicated, chromosomal translocation will be investigated using appropriate molecular genetic 
and cytogenetic methods. In suspected cases of SMZL with CD5 positivity, at (11;14) must be eliminated 
by FISH. 
 
For each enrolled patient, the paraffin embedded tissue block should be sent to collecting centres (see 
contact addresses for the trial organization for LYSA and FIL centers) for processing; the block will be 
returned as soon as possible. If for local reasons, it is not possible to release the paraffin embedded 
tissue block, the following specimens should be submitted to collecting centres: one slide stained with 
H&E and 14 unstained sections (for immunohistochemistry and FISH), of each tumor bioptic sample 
(bone marrow, spleen, lymphonode). 
For each enrolled patient, peripheral blood smears/bone marrow aspirate should be sent to collecting 
centres (see contact addresses for the trial organization for LYSA and FIL centers). The slides will be 
returned as soon as possible.

APPENDIX B - World Medical Association 
Declaration of Helsinki 
Ethical Principles for 
Medical research involving Human Subjects 
 
Adopted by the 18th WMA General Assembly, 
 Helsinki, Finland, June 1964, and amended by the: 
29th WMA General Assembly, Tokyo, Japan, October 1975 
35th WMA General Assembly, Venice, Italy, October 1983 
41st WMA General Assembly, Hong Kong, September 1989 
48th WMA General Assembly, Somerset West, Republic of South Africa, October 1996 
52nd WMA General Assembly, Edinburgh, Scotland, October 2000  
53rd WMA General Assembly, Washington 2002 (Note of Clarification on paragraph 29 added) 
55th WMA General Assembly, Tokyo 2004 (Note of Clarification on Paragraph 30 added) 
59th WMA General Assembly, Seoul, October 2008 
 
INTRODUCTION  
1.
The World Medical Association (WMA) has developed the Declaration of Helsinki as a statement of 
ethical principles for medical research involving human subjects, including research on identifiable 
human material and data.  
The Declaration is intended to be read as a whole and each of its constituent paragraphs should 
not be applied without consideration of all other relevant paragraphs.  
2.
Although the Declaration is addressed primarily to physicians, the WMA encourages other 
participants in medical research involving human subjects to adopt these principles.  
3.
It is the duty of the physician to promote and safeguard the health of patients, including those who 
are involved in medical research. The physician's knowledge and conscience are dedicated to the 
fulfilment of this duty.  
4.
The Declaration of Geneva of the WMA binds the physician with the words, "The health of my 
patient will be my first consideration," and the International Code of Medical Ethics declares that, 
"A physician shall act in the patient's best interest when providing medical care."  
5.
Medical progress is based on research that ultimately must include studies involving human 
subjects. Populations that are underrepresented in medical research should be provided 
appropriate access to participation in research.  
6.
In medical research involving human subjects, the well-being of the individual research subject 
must take precedence over all other interests.  
7.
The primary purpose of medical research involving human subjects is to understand the causes, 
development and effects of diseases and improve preventive, diagnostic and therapeutic 
interventions (methods, procedures and treatments). Even the best current interventions must be 
evaluated continually through research for their safety, effectiveness, efficiency, accessibility and 
quality.  
8.
In medical practice and in medical research, most interventions involve risks and burdens.  
9.
Medical research is subject to ethical standards that promote respect for all human subjects and 
protect their health and rights. Some research populations are particularly vulnerable and need 
special protection. These include those who cannot give or refuse consent for themselves and 
those who may be vulnerable to coercion or undue influence.  
10. Physicians should consider the ethical, legal and regulatory norms and standards for research 
involving human subjects in their own countries as well as applicable international norms and 
standards. No national or international ethical, legal or regulatory requirement should reduce or 
eliminate any of the protections for research subjects set forth in this Declaration. 
 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
42 
BASIC PRINCIPLES FOR ALL MEDICAL RESEARCH  
11. It is the duty of physicians who participate in medical research to protect the life, health, dignity, 
integrity, right to self-determination, privacy, and confidentiality of personal information of 
research subjects.  
12. Medical research involving human subjects must conform to generally accepted scientific 
principles, be based on a thorough knowledge of the scientific literature, other relevant sources of 
information, and adequate laboratory and, as appropriate, animal experimentation. The welfare of 
animals used for research must be respected.  
13. Appropriate caution must be exercised in the conduct of medical research that may harm the 
environment.  
14. The design and performance of each research study involving human subjects must be clearly 
described in a research protocol. The protocol should contain a statement of the ethical 
considerations involved and should indicate how the principles in this Declaration have been 
addressed. The protocol should include information regarding funding, sponsors, institutional 
affiliations, other potential conflicts of interest, incentives for subjects and provisions for treating 
and/or compensating subjects who are harmed as a consequence of participation in the research 
study. The protocol should describe arrangements for post-study access by study subjects to 
interventions identified as beneficial in the study or access to other appropriate care or benefits.  
15. The research protocol must be submitted for consideration, comment, guidance and approval to a 
research ethics committee before the study begins. This committee must be independent of the 
researcher, the sponsor and any other undue influence. It must take into consideration the laws 
and regulations of the country or countries in which the research is to be performed as well as 
applicable international norms and standards but these must not be allowed to reduce or eliminate 
any of the protections for research subjects set forth in this Declaration. The committee must have 
the right to monitor ongoing studies. The researcher must provide monitoring information to the 
committee, especially information about any serious adverse events. No change to the protocol 
may be made without consideration and approval by the committee.  
16. Medical research involving human subjects must be conducted only by individuals with the 
appropriate scientific training and qualifications. Research on patients or healthy volunteers 
requires the supervision of a competent and appropriately qualified physician or other health care 
professional. The responsibility for the protection of research subjects must always rest with the 
physician or other health care professional and never the research subjects, even though they have 
given consent.  
17. Medical research involving a disadvantaged or vulnerable population or community is only justified 
if the research is responsive to the health needs and priorities of this population or community and 
if there is a reasonable likelihood that this population or community stands to benefit from the 
results of the research.  
18. Every medical research study involving human subjects must be preceded by careful assessment of 
predictable risks and burdens to the individuals and communities involved in the research in 
comparison with foreseeable benefits to them and to other individuals or communities affected by 
the condition under investigation.  
19. Every clinical trial must be registered in a publicly accessible database before recruitment of the 
first subject.  
20. Physicians may not participate in a research study involving human subjects unless they are 
confident that the risks involved have been adequately assessed and can be satisfactorily managed. 
Physicians must immediately stop a study when the risks are found to outweigh the potential 
benefits or when there is conclusive proof of positive and beneficial results.  
21. Medical research involving human subjects may only be conducted if the importance of the 
objective outweighs the inherent risks and burdens to the research subjects.  
22. Participation by competent individuals as subjects in medical research must be voluntary. Although 
it may be appropriate to consult family members or community leaders, no competent individual 
may be enrolled in a research study unless he or she freely agrees.  

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
43 
23. Every precaution must be taken to protect the privacy of research subjects and the confidentiality 
of their personal information and to minimize the impact of the study on their physical, mental and 
social integrity.  
24. In medical research involving competent human subjects, each potential subject must be 
adequately informed of the aims, methods, sources of funding, any possible conflicts of interest, 
institutional affiliations of the researcher, the anticipated benefits and potential risks of the study 
and the discomfort it may entail, and any other relevant aspects of the study. The potential subject 
must be informed of the right to refuse to participate in the study or to withdraw consent to 
participate at any time without reprisal. Special attention should be given to the specific 
information needs of individual potential subjects as well as to the methods used to deliver the 
information. After ensuring that the potential subject has understood the information, the 
physician or another appropriately qualified individual must then seek the potential subject's 
freely-given informed consent, preferably in writing. If the consent cannot be expressed in writing, 
the non-written consent must be formally documented and witnessed.  
25. For medical research using identifiable human material or data, physicians must normally seek 
consent for the collection, analysis, storage and/or reuse. There may be situations where consent 
would be impossible or impractical to obtain for such research or would pose a threat to the 
validity of the research. In such situations the research may be done only after consideration and 
approval of a research ethics committee.  
26. When seeking informed consent for participation in a research study the physician should be 
particularly cautious if the potential subject is in a dependent relationship with the physician or 
may consent under duress. In such situations the informed consent should be sought by an 
appropriately qualified individual who is completely independent of this relationship.  
27. For a potential research subject who is incompetent, the physician must seek informed consent 
from the legally authorized representative. These individuals must not be included in a research 
study that has no likelihood of benefit for them unless it is intended to promote the health of the 
population represented by the potential subject, the research cannot instead be performed with 
competent persons, and the research entails only minimal risk and minimal burden.  
28. When a potential research subject who is deemed incompetent is able to give assent to decisions 
about participation in research, the physician must seek that assent in addition to the consent of 
the legally authorized representative. The potential subject's dissent should be respected.  
29. Research involving subjects who are physically or mentally incapable of giving consent, for 
example, unconscious patients, may be done only if the physical or mental condition that prevents 
giving informed consent is a necessary characteristic of the research population. In such 
circumstances the physician should seek informed consent from the legally authorized 
representative. If no such representative is available and if the research cannot be delayed, the 
study may proceed without informed consent provided that the specific reasons for involving 
subjects with a condition that renders them unable to give informed consent have been stated in 
the research protocol and the study has been approved by a research ethics committee. Consent to 
remain in the research should be obtained as soon as possible from the subject or a legally 
authorized representative.  
30. Authors, editors and publishers all have ethical obligations with regard to the publication of the 
results of research. Authors have a duty to make publicly available the results of their research on 
human subjects and are accountable for the completeness and accuracy of their reports. They 
should adhere to accepted guidelines for ethical reporting. Negative and inconclusive as well as 
positive results should be published or otherwise made publicly available. Sources of funding, 
institutional affiliations and conflicts of interest should be declared in the publication. Reports of 
research not in accordance with the principles of this Declaration should not be accepted for 
publication.

ADDITIONAL PRINCIPLES FOR MEDICAL RESEARCH COMBINED WITH MEDICAL CARE  
31. The physician may combine medical research with medical care only to the extent that the 
research is justified by its potential preventive, diagnostic or therapeutic value and if the physician 
has good reason to believe that participation in the research study will not adversely affect the 
health of the patients who serve as research subjects.  
32. The benefits, risks, burdens and effectiveness of a new intervention must be tested against those 
of the best current proven intervention, except in the following circumstances:  
33. The use of placebo, or no treatment, is acceptable in studies where no current proven intervention 
exists; or  
34. Where for compelling and scientifically sound methodological reasons the use of placebo is 
necessary to determine the efficacy or safety of an intervention and the patients who receive 
placebo or no treatment will not be subject to any risk of serious or irreversible harm. Extreme care 
must be taken to avoid abuse of this option.  
35. At the conclusion of the study, patients entered into the study are entitled to be informed about 
the outcome of the study and to share any benefits that result from it, for example, access to 
interventions identified as beneficial in the study or to other appropriate care or benefits.  
36. The physician must fully inform the patient which aspects of the care are related to the research. 
The refusal of a patient to participate in a study or the patient's decision to withdraw from the 
study must never interfere with the patient-physician relationship.  
37. In the treatment of a patient, where proven interventions do not exist or have been ineffective, 
the physician, after seeking expert advice, with informed consent from the patient or a legally 
authorized representative, may use an unproven intervention if in the physician's judgement it 
offers hope of saving life, re-establishing health or alleviating suffering. Where possible, this 
intervention should be made the object of research, designed to evaluate its safety and efficacy. In 
all cases, new information should be recorded and, where appropriate, made publicly available.

classification. Cancer. Res. 31:1860-1861, 1971. ** Lister TA, Crowther D, Sutcliffe SB, et al. Staging for Hodgkin's 
disease. Report of a committee convened todiscuss the evaluation and staging of patients with Hodgkin's disease: 
Cotswolds meeting. J. Clin. Oncol. 7:1630-1636,1989 [Erratum J. Clin. Oncol. 8:1602, 1990]) 
 
Stage I: involvement of a single lymphatic region (I), or localized involvement of a single extralymphatic 
organ or site (IE). 
Stage II: involvement of two or more lymphatic regions on the same side of diaphragm (II) or localized 
involvement of an extralymphatic organ or site and one or more lymph node regions the same side of 
diaphragm (IIE). 
Stage III: involvement of two or more lymphatic regions on both sides of diaphragm (III) which may also 
be accompanied either by localized involvement of an extralymphatic organ or site (IIIE), or by 
involvement of the spleen (IIIS). 
Stage IV: Diffuse or disseminated involvement of one or more extralymphatic organs or tissue, with or 
without associated lymph node involvement. 
Bone marrow or liver involvement will always be considered as stage IV. 
 
Lymphatic structures include lymph nodes, spleen, thymus, Waldeyer’s ring including tonsils. The 
lymphatic regions are defined according to Ann Arbor as (a) clinical enlargement of a node when 
alternative pathology may reasonably be ruled out (suspicious nodes should always be biopsied if 
treatment decisions are based on their involvement) ; and (b) enlargement on plain radiograph, CT 
scan, or lymphography. 
Localized involvement of an extralymphatic site (extranodal site or E-lesion) is diagnosed when the 
involvement is small enough to be in principle accessible for curative radiotherapy (thereby excluding 
diffuse organ involvement corresponding to stage IV). 
 
Criteria for “B” symptoms 
The presence of (a) unexplained weight loss of more than 10% of the body weight during the 6 months 
before initial staging investigation and/or (b) unexplained, persistent, or recurrent fever with 
temperatures above 38°C during the previous month and/or (c) recurrent drenching night sweats 
during the previous months is denoted by the suffix letter ‘B’. ‘A’ indicates the absence of these 
symptoms.  
 
Criteria for bulk disease 
The bulk of palpable lymph nodes will be defined by the largest dimension (cm) of the single largest 
Iymph node or conglomerate node mass in each region of involvement. A node or nodal mass must be 
10 cm or greater to be recorded as "bulky". 
A mediastinal mass will be defined as "bulky" on a postero-anterior chest radiograph, when the 
maximum width is equal or greater than one-third of the internal transverse diameter of the thorax at 
the T5-T6 level. The chest radiography should be taken with maximal inspiration in the upright position 
at a source-skin distance of 2 m. 
 
Spleen bulky is arbitrarily defined as spleen ≥6 cm below left costal margin.

APPENDIX L 
Instruction for Preparation and Handling of Bendamustine 
 
Refer to the clinical trial protocol for details about the dose and dose schedule. 
Bendamustine should not be administered to patients with known hypersensitivity to 
bendamustine or mannitol.   
 
A licensed pharmacist or a properly trained designee will prepare all doses of bendamustine. It 
is very important that the exact dose is accurately dispensed and administered. If possible, the 
same person should prepare all doses (on all dosing days). Bendamustine will be administered 
only to eligible subjects under the supervision of the investigator or identified 
subinvestigator(s). 
 
Calculation of Dose 
The amount (in mg) of bendamustine to be administered will be determined based on body 
surface area (BSA). BSA will be calculated based on body weight and height using a standard 
calculation (Appendix K, Suggested Body Surface Area Calculation). The bendamustine dose 
will not be corrected for obese subjects. The dose should be calculated on Day 1 of each cycle 
and remain consistent during an individual cycle. The dose administered should remain 
consistent across cycles unless a notable change in weight (e.g., loss or gain of ı10%) is 
documented during the Day 1 weight assessment of the cycle, in which case the subject’s dose 
should be recalculated at that time. In the event of bendamustine-associated toxicity during 
the study, the dose may be decreased according to the dose reduction schedules provided in 
Section 4.6.1. 
 
Reconstruction and Dilution 
Reconstruction 
Reconstitute each vial containing 25 mg bendamustine hydrochloride in 10 ml water for 
injection by shaking; 
Reconstitute each vial containing 100 mg bendamustine hydrochloride in 40 ml water for 
injection by shaking. 
The reconstituted concentrate contains 2.5 mg bendamustine hydrochloride per ml and 
appears as a clear colourless solution 
Dilution 
As soon as a clear solution is obtained (usually after 5-10 minutes) dilute the total 
recommended dose immediately with 0.9% NaCl solution to produce a final volume of about 
500 ml. 
Bendamustine must be diluted with 0.9% NaCl solution and not with any other injectable 
solution. 

 
IELSG-36 – Version 5.1 – November 22, 2017 
 
51 
 
Administration of bendamustine 
The final admixture is stable 3.5 hours when stored at room temperature (25°C) and room 
light. Administration of bendamustine must be completed within this period. 
The administration of bendamustine, reconstituted and diluted according to the above 
prescriptions will be accomplished by slow I.V. infusion in an out- or in-patient setting over 
approximately 30 to 60 minutes).  
 
CAUTION: DO NOT ADMINISTER AS AN INTRAVENOUS PUSH OR BOLUS 
 
Discarding of Vials and Syringe 
After administration all materials that have been used for preparation should be disposed of 
according to standard practices. Any unused solution should be discarded according to institutional 
procedures for antineoplastics. 
All unused vials must be saved for reconciliation by the study monitor. A log must be kept of all 
disposed materials.  
 
Procedures to follow in case of body contact 
Inhalation: if inhaled, remove to fresh air. If breathing becomes difficult, call a physician. 
Skin: in case of skin contact, flush with copious amounts of water for at least 15 minutes. 
Remove contaminated clothing and shoes. 
Ingestion: if swallowed, wash out mouth with water provided person is conscious. Call a 
physician. 
Eyes: in case of contact with eyes, flush with copious amount of water for at least 15 minutes. 
Assure adequate flushing by separating eyelids 
Always contact the investigator after any form of body contact.

APPENDIX M 
Guidelines for Management of Biological Material 
 
The consent process allows for paraffin embedded blocks of tumour (bone marrow, spleen), peripheral 
blood smears, anticoagulated blood samples and anticoagulated bone marrow samples, serum 
(collectively defined in this protocol as study material) to be submitted for central histology review, 
cytogenetic analysis and immunoglobulin gene repertoire and mutation analysis.

LYSA Centers 
 
SAMPLES FOR PATHOLOGY REVIEW OF SPLEEN/BONE MARROW 
The pathological diagnosis of SMZL should have been first performed locally and will be used for the 
inclusion.  
A central review of the diagnosis will be then organized by the LYSA-P Institute for each patient 
included in the trial. Diagnosis will be established according to WHO classification for splenectomized 
cases1 and according to the Splenic Lymphoma Group recommendations for non splenectomized 
cases13,  with full support of immunohistochemistry. At patient screening, the investigator will be 
requested to join with the form of inclusion a copy of the histopathological report where the name and 
address of the pathologist having diagnosed the lymphoma will be easily identified. However, in the 
case where no histopathological report is available, the name and address of the initial pathologist as 
well as the report number will have to be indicated on the inclusion form.  
The LYSA-P Institute will then organize and centralize the collection of the bone marrow biopsy and 
spleen (if available) material. At reception of the material, routinely stained sections will be performed 
and an appropriate panel of antibodies according to morphological aspects will be applied.  
Tissue microarray (TMA) will also be constructed. Three tissue cylinders representative of tumor regions 
with a diameter of 0.6 mm will be punched from the paraffin embedded tissue and transferred into a 
recipient paraffin block using a manual tissue arrayer (Beecher Instruments). Reactive lymphoid tissues 
will also be included in the TMA blocks, as a control and two twin TMA blocks will be prepared, 
according to the procedure used in the LYSA-P. 
The prepared stained slides will be reviewed by a panel of pathologist based on expert 
hematopathologists who will establish a consensus diagnosis. When the review process is achieved and 
the tissue array performed, a pathological report is sent to the initial pathologist as well as the 
investigator of the inclusion centre. The remaining material is sent back to the initial pathologist. 
The LYSA-P will make the commitment to respect the legal requirements for the collection, preparation 
and  storage of the samples. 
 
SAMPLES FOR CYTOLOGY REVIEW ON BLOOD AND BONE MARROW ASPIRATE 
At screening, peripheral blood smears (2 stained slides + 1 blank slide) and bone marrow aspirate (2 
stained slides + 1 blank slide) will be shipped with the completed traceability form in a pre-paid 
enveloped by regular mail. 
 
 
 
SAMPLES FOR MINIMAL RESIDUAL DISEASE (MRD) 
Flow-cytometry immunophenotype and IgVH gene rearrangement (antiCDR3) analyses (molecular B cell 
clonality assay ) will be performed on the peripheral blood and the bone marrow aspirate at baseline 
(screening phase),  at each restaging phases, at end of the treatment and at intervals (one a year) 
during follow up. 
For FACS analyses, 5 ml x 2 EDTA blood and 3 ml x 1 EDTA bone marrow will be required and will be 
sent by DHL to guarantee a delivery in 48h in centralized lab with a shipment form. 

 
IELSG-36 – Version 5.1 – November 22, 2017

special isolation tube (PAXgene tube) and labels will be provided by LYSARC. This PAXgene tube will be 
send on the day of collection by regular mail at room temperature.  
 
The results of MRD will be not incorporated into the response evaluation nor influence the 
management of the patient. 
 
 
SAMPLES FOR QMPFS  
A specific informed consent form will be used to allow the collection of blood samples for DNA 
preparation. It is highly recommended to collect blood samples (10 ml on EDTA or on paxgene tube) at 
diagnosis in all patients of each LYSA center.  
A special isolation tube (the same PAXgene tube used for IgVH at baseline) and labels will be provided 
by LYSARC. This PAXgene tube will be sent on the day of collection by regular mail at room 
temperature.

Description of Minimal Residual Disease, and molecular, 
genetic and cytogenetic investigations

LYSA Centers 
·
Minimal residual Disease (MRD) 
There are strong hints from recently published data that minimal residual disease (MRD) detection may 
play a role as a prognostic factor in patients with small B cell lymphomas such as mantle cell lymphoma. 
Nothing has been reported in Splenic Marginal Zone lymphoma. But this method could help to assess 
the status of complete response because evaluation of response in SMZL may not be easy even if 
criteria have been published (Matutes et al. 2008).  
Aim of MRD analysis within this study protocol is the monitoring of MRD by Flow cytometry and by 
quantitative Taq Man PCR (RQ-PCR) targeting clonal IgVH (antiCDR3) to evaluate the prognostic impact 
of MRD on progression free survival and long-term remission of patients with splenic marginal zone 
lymphoma.  
FACS analysis will be performed at baseline, after C4, after C6 and every year, to evaluate the B cell 
background during treatment with Rituximab. Therefore it is essential to send heparin blood/ bone 
marrow for FACS analysis together with EDTA blood/ bone marrow for FACS analysis at every time point 
of MRD investigation. 
The real time PCR method is sensitive enough to detect a lymphoma cell in the background of 104-105 
normal cells. PCR-analysis will be performed from peripheral blood (10 ml EDTA blood) and bone 
marrow (3-5 ml EDTA bone marrow aspirate). As a prerequisite for molecular assessment of MRD using 
RQ-PCR peripheral blood and bone marrow has to be sent before start of any treatment to determine 
the individual patient-specific DNA-sequence of the malignant clone. It will then realized at the 
timepoint than FACS analysis (C4, C6, and once a year). 
Flow-cytometry immunophenotype and IgVH gene rearrangement analyses  (molecular B cell clonality 
assay ) will be performed on the peripheral blood and the bone marrow aspirate at  baseline (screening 
phase),  at each restaging phases, at end of the treatment and at intervals during follow up. 
The results of MRD will be not incorporated into the response evaluation nor influence the 
management of the patient. 
 
Chromosomal abnormalities by QMPSF– C. Bastard 
Analysis of chromosomal copy number abnormalities will be performed from DNA extracted from blood 
collected at baseline: +3 ; del7 ; +12 ; +18

Immunoglobulin heavy-chain variable-region (IgVH ) gene mutation analysis – F. Davi 
Analysis of IgVH genes expressed by tumor cells will be undertaken for both mutational status and 
repertoire evaluation. Nucleotide sequence of IgVH genes will be performed according to standardized 
protocols (Ghia et al., Leukemia, 2007, 21:1). Briefly, clonal IgVH  rearrangements will be amplified 
from genomic DNA (0,5-2 micrograms) using 5’ primers corresponding to the framework 1 (or peptide 
leader) region and 3’ primers corresponding to the J genes. PCR products will be sequenced directly or 
after cloning if necessary. Sequence analysis including identification of the closest germline gene 
counterpart, distribution and characteristics of somatic mutations will be performed using dedicated 
bioinformatic tools (IMGT V-QUEST, IgBlast).

Flow-cytometry immunophenotype and IgVH gene rearrangement analyses (molecular B cell clonality 
assay) will be performed on the peripheral blood and the bone marrow aspirate at  baseline (screening 
phase), at each restaging phases, at end of the treatment and at intervals during follow up. Cytogenetic 
assessment and IgVH mutation analyses will be performed at baseline only. Table 6.8 of the protocol 
summarises the time schedule of the required investigations (row g,h). 
Samples 
Mononuclear cells (MNC) will be isolated from peripheral blood and /or bone marrow aspirate by ficoll 
hypaque density gradient centrifugation. MNC will be splitted in three aliquots to perform the following 
different analysis: flow cytometry, cytogenetic assessment, molecular analysis (B cell clonality assay and 
IgVH mutation analysis).  
 
Flow cytometry 
Immunophenotype analysis by flow cytometry will be performed on fresh MNC using the following 
monoclonal antibodies (moAb): CD3+, CD4+, CD8+, CD19+, CD20+, CD5+, CD10+, CD23+, CD11c+, 
FMC7+, CD103, CD25, SIg, SIgM, SIgG, SIgD, K, L). CD22+, CD43+, Cd103+, CD25+, CD123+. Four color 
stainings will be performed using moAb conjugated with four different fluorochromes and using 
FACSalibur cytometer (BD biosciences). The acquired data will be analyzed by Cell Quest software. 
Chromosomal abnormalities 
Analysis of chromosomal abnormalities will be performed from DNA extracted from MNC from 
periphera blood or bone marrow aspirates (only in the case of peripheral blood without neoplastic 
cells): +3 ; del7 ; +12 ; +18. 
Molecular analysis 
The detection of IgVH gene rearrangements (B cell clonality assay) will be performed by fluorochrome 
labeled PCR as described in the protocol BIOMED 2 PCR (Leukemia 2003 17: 2257-2317). The 
fluorochrome labeled PCR products will be analyzed by GeneScanning analysis using ABI prism 3100 
Avant Genetic Analyser. GeneScanning analysis of IgVH rearrangements have been developed for B cell 
clonality studies with a sensitive of clonal populations of >1%, (not for detection of subclones <1%). 
 
Immunoglobulin heavy-chain variable-region (IgVH) gene mutation analysis will be performed as 
described in Dono M et al. J Immunol. 2000 Jun 1;164(11):5596-604. Briefly, clonal IgVH 
rearrangements will be amplified from genomic DNA using 5’ primers corresponding to the VH leaders 
or VH framework 1 region and 3’ primers corresponding to the JH genes. PCR products will be 
sequenced directly by Sanger method using ABI prism 3100 Avant Genetic Analyser. Sequence analysis 
including identification of the closest germline gene counterpart, distribution and characteristics of 
somatic mutations will be performed using dedicated bioinformatic tools (IMGT V-QUEST, IgBlast).

APPENDIX P 
Procedures for AE, SAE and SUSAR reporting
Patients will be instructed by the investigator to report the occurrence of any AE. The 
investigator assesses and records all AEs observed during the AE reporting period  (i.e. from 
inclusion until 30 days after end of treatment).
AEs are coded with the NCI Common Terminology Criteria for Adverse Events (CTCAE) v4.0 
(appendix J) and assigned a grade (from 1 = mild to 5 = death related to AE) as well as a 
relationship (suspected vs not suspected)  to trial treatment.
Any SAE must be reported within 24 hours (working days) by completing the “SAE Report form” 
and sending it by fax/email attachment to IELSG Study Coordination:
IELSG Study Coordination
Oncology Institute of Southern Switzerland
Ospedale San Giovanni
CH - 6500 Bellinzona
Phone 0041 91 811 9040
Fax
0041 91 811 9182
E-mail ielsg@ticino.com
SAE reporting period is from inclusion until 30 days after end of treatment.
The SAE outcome must be reported within 2 weeks after definitive assessment by completing 
the “SAE Report form” and sending it by fax/email attachment again to IELSG Coordinating 
Center.
The investigator according to local regulations will inform local authorities (ethic committees). 
The physician responsible for patient care should organize any supplementary investigation of 
serious adverse events based on the clinical judgement on the likely causing factors. These 
means include seeking a further opinion from a specialist in the field of the adverse event. If a 
patient dies, any post mortem finding including histopathology must be provided.
The sponsor (IELSG) shall be responsible for ensuring that any SAEs are appropriately 
reported to the relevant health authorities according to applicable laws and regulations in each 
country where the Study will be conducted and to perform any additional activities.

APPENDIX Q 
 
FDG-PET reviewing
 
In the literature, many published reviews and the guidelines by the main onco-hematological scientific 
associations consider it is still controversial to role the 18F-FDG PET in the staging/restaging of the 
MALT lymphomas, recommending a standard radiological approach with contrast enhanced CT. 
However, recent clinical meta-analysis (Treglia G, Hematol Oncol 2015) and retrospective study 
(carrillo-Cruz E, Hematol Oncol) seems to indicate a potential clinical role of 18F-FDG PET or PET/CT in 
the initial evaluation of patients with SMZL. 
In particular, the meta-analysis study adds significant novelty in this setting, underlining that MALT 
lymphomas are 18F-FDG-avid tumours in most of the cases, in particular in those with primary head-
and-neck and bronchial locations.  
Moreover, the retrospective study suggest that PET/CT has a high sensitivity in newly diagnosed 
patients with MZL and therefore can be useful in the staging of patients with nodal and extranodal 
subtypes. The technique is more sensitive than a CT scan at initial staging, mainly in cases with 
extranodal involvement. Although a larger number of patients will be required to further confirm these 
data, the study can conclude that PET/CT is a valuable imaging tool for both staging and response 
assessment in patients with NMZL and MALT lymphoma. 
 
Also the analysis of clinical response conducted in IELSG36/BRISMA study has clearly demonstrated that 
the classic criteria based on physical examination and CT scan are far for being accurate. Particularly in 
patients showing a small splenomegaly as only sign of residual disease at the end of treatment it is very 
difficult differentiate complete responses from partial responses. 
 
Due to these considerations, a centralized PET scan evaluation will be performed; the anonymized PET 
scan images will be collected and preserved for the entire duration of the study at the LYSARC (Resp. 
Romain Ricci, Coordinator Imaging LYSARC, CHU Henri Mondor Créteil, Service de Médecine Nucléaire). 
The images will be evaluated by a group of expert nuclear medicine to analyze the clinical response of 
the patients (Dr. Salim Kanoun, Service de Medecine Nucleaire  IUCT-ONCOPoLE, Institut C. Regaud, 
Toulouse, France and Dr. Luc Fornecker, Service d'Oncologie et d'Hématologie, Hôpitaux Universitaires 
de Strasbourg, Strasbourg, France). 
The primary objective of this ancillary study was to evaluate the role of 18FDG/PET in SMZL at diagnosis 
for staging and as predictor of the treatment outcome including the response to treatment, the 
progression free survival and the time to next treatment.

The secondary objectives are the prognostic value of interim and post-R-benda PET and the prognostic 
value of the metabolic volume associated with biological markers.
