Abstract: Mantle cell lymphoma (MCL) is an uncommon type of non- Hodgkin lymphoma (NHL) comprising 〈 10% of all newly diagnosed patients. Classified as an aggressive NHL subtype, MCL has the worst prognosis of B-cell subtypes owing to its aggressive clinical disease course and incurability with standard chemo-immunotherapy. Conventional first-line therapy for bulky or advanced disease primarily consists of chemotherapy combined with rituximab, with possible consolidation with autologous stem cell transplantation for younger patients in remission to improve overall patient outcomes. However, options for relapsed MCL are limited although several single agents have been studied. Lenalidomide is available in Italy for patients with MCL (without any other therapeutic options) since May 2011, based on a local disposition of the Italian Drug Agency (AIFA) issued according to a national law (Law 648/96: "medicinal products that are provided free of charge on the national health service"). An observational retrospective study was conducted in 24 Italian hematology centers with the aim to improve information on efficacy and safety of lenalidomide use in real practice. Seventy patients received lenalidomide for 21/28 days with a median of 8 cycles. Doses (range 5-25 mg/day) were according to hematologic parameters. At the end of therapy there were 22 complete responses (31.4%), 9 partial responses, 6 stable diseases and 33 progressions with an overall response rate of 44.3%. Sixteen patients (22.9%) received lenalidomide in combination either with dexamethasone (N=12) or with rituximab (N=4). At 62 months overall survival (OS) was 26.2% (median reached at 33 months) and disease free survival (DFS) 37% at 42 months: 14/22 patients are in continuous complete response with a median of 26 months. We compared patients who received lenalidomide alone with patients who received lenalidomide in combination with other drugs: OS and DFS did not differ. Progression free survivals are significantly different: at 56 months 36% in combination group vs 13% in patients who received lenalidomide alone (p=0.04, hazard ratio 0.52). Toxicities were manageable, even if 17 of them led to an early drug discontinuation. Two secondary malignancies occurred: a myelodysplastic syndrome and a lung cancer after 10 and 15 months of therapy, respectively. There is a boundary zone in the passage from phase III to phase IV trials, i.e. from experimental to marketing and free use phases: in this zone we can find named patient program, compassionate and off-label use and, in Italy, request based on a local disposition. Despite the known potential bias of all the observational studies, reports on the real life experience make an important contribution to medical knowledge prior to market authorization: lenalidomide therapy is effective and tolerable also in compassionate use patients with good survival. Our results, in fact, are superimposable to those obtained in clinical trials. Disclosures Rusconi: Roche: Honoraria.

Results Seventy patients received lenalidomide for 21/28 days with a median of eight cycles. At the end of therapy, there were 22 complete responses (31.4%), 11 partial responses, 6 stable diseases, and 31 progressions, with an overall response rate of 47.1%. Eighteen patients (22.9%) received lenalidomide in combination with either dexamethasone (n = 13) or rituximab (n = 5). Median overall survival (OS) was reached at 33 months and median disease-free survival (DFS) at 20 months: 14/22 patients are in continuous complete response with a median of 26 months. Patients who received lenalidomide alone were compared with patients who received lenalidomide in combination: OS and DFS did not differ. Progression-free survivals are significantly different: at 56 months, 36% in the combination group versus 13% in patients who received lenalidomide alone. Toxicities were manageable, even if 17 of them led to an early drug discontinuation. Conclusion Lenalidomide therapy for relapsed MCL patients is effective and tolerable even in a real-life context. Implication for Practice Several factors influence treatment choice in relapsed/refractory mantle cell lymphoma (rrMCL), and the therapeutic scenario is continuously evolving. In fact, rrMCL became the first lymphoma for which four novel agents have been approved: temsirolimus, lenalidomide, ibrutinib, and bortezomib. The rrMCL therapeutic algorithm is not so well established because data in the everyday clinical practice are still poor. Lenalidomide for rrMCL patients is effective and tolerable even in a real-life context.

Abstract: Background. BV, an anti-CD30 antibody-drug conjugate, has been approved for the treatment of Hodgkin lymphoma (HL) and ALCL. Of interest, BV has shown activity in PTCLs other than ALCL that express low or even undetectable levels of CD30. In particular BV has been reported effective in angioimmunoblastic T-cell lymphoma (AITL) and peripheral T-cell lymphoma not otherwise specified (PTCL-nos). Here, we report 4 cases with relapsed/resistant PTCLs (1 AITL, 1 NK-T nasal type, 1 PTCL with T-helper follicular phenotype-PTCL-TFH and 1 PTCL-nos) who responded to BV therapy. Results. On August 2014, a 53-y-old caucasian male was diagnosed with 5% CD30-positive AITL. The final stage was IIIA, because of a single left axillar node was documented at the PET-TC scan in addition to the excised inguinal lymphadenopathy. A complete metabolic PET remission (PET-CR) was documented after the 3th and confirmed after the 6th cycle of cyclophosphamide, doxorubicin, vincristine, etoposide and prednisone (CHOEP). However, relapsing disease was documented 6 mths later. At that time, diffuse over and under-diaphragm nodal involvement was observed. A PET-CR was achieved after 2 cycles of dexamethasone, cytarabine, and cisplatin (DHAP), but disease progressed shortly after the 4th cycle before the planned autotransplantation (ASCT). A 3th line chemotherapy, consisting of mitoxantrone and high dose ARA-C (modified HAM), was performed and failed to control the disease. Furthermore HAM chemotherapy was associated with severe infectious complications (sepsis from MDR S. Epidermidis and pulmonary aspergillosis). On December 2015, BV was begun. A PET-CR was documented after the 4th and confirmed after the 8th cycle of therapy. The patients is still in CR, in continuous therapy (12th cycle), waiting for HLA matched unrelated donor. On July 2012 a 62-y-old caucasian man was diagnosed with extranodal NK/T-cell nasal type lymphoma. Both Epstein Barr virus (EBV) and CD30 molecule were not expressed by neoplastic cells. Weekly cisplatin and radiotherapy were concomitantly given followed by 3 cycles of etoposide, ifosfamide, cisplatin and dexamethasone. This treatment resulted in PET-CR. At the time of first relapse (Nov 2013), 3 cycles of methotrexate, L-asparaginase and dexamethasone, followed by ASCT (fotemustine, etoposide, cytarabine, melphalan), induced a 2nd PET-CR. However, two subsequent PET evaluations suggested the presence of active disease shortly after (December 2015) a biopsy proven relapse was documented. A PET-CR was observed after 2 and confirmed after 7 cycles of single agent BV. The patient is still undergoing treatment. On September 2015, a 49-y-old african man was diagnosed with PTCL-THF, showing AITL signs, with both EBV and CD30 positive (50-75%) Hodgkin/Reed-Sternberg cells. A progressive disease was documented after the 4th cycle of CHOEP. At that time, patient was not candidate to receive further chemotherapy, because of worsening of perfomance status (PS). BV, given as salvage therapy, resulted in a rapid control of all signs and symptoms after the 6th administration. Because of improved PS and a partial metabolic remission, the DHAP combination was begun on June 2016 and ASCT is now planned as consolidation. On November 2009, a 46-y-old caucasian man was diagnosed with classical HL. The final stage was IEA. The disease was refractory to doxorubicin, bleomycin, vinblastine, dacarbazine and radiotherapy. A PET-CR was achieved in response to ifosfamide, gemcitabine, vinorelbine and prednisone chemotherapy. After 3 yrs, a lymph node biopsy confirmed a relapsed HL. Four cycles of DHAP followed by ASCT resulted in a 2nd PET-CR. After 3 mths, a PTCL-NOS associated with blastic lymphoid B EBV positive cells was diagnosed on an excisional lymph node biopsy. On May 2014 BV as single-agent was started. A PET-CR lasted for 8 mths. Relapsing disease was documented on January 2015. The patient refused further chemotherapy and died because of disease progression on July 2015. Conclusion. In this experience BV, regardless of CD30 expression, has shown significant clinical activity in recurrent or refractory T-cell lymphomas and no significant toxicity, even in heavily pretreated patients. In consideration of the BV activity in PTCLs, combination studies with other molecules, such as romidepsine, are desirable. Disclosures No relevant conflicts of interest to declare.

Abstract: Introduction Limited stage follicular lymphoma (FL) is usually managed with involved field radiotherapy (IFRT), although different approaches are currently carried out, ranging from watch and wait to combined treatment. RT on involved lymph nodes allows eradication of the disease only in 40-50% of patients. Anti-CD20 monoclonal antibodies (MoAb), widely used in advanced stage FL, are likely to be effective in reducing the relapse risk, although no scientific evidence of their role has been provided. The aim of this multicenter phase II prospective study was to evaluate the role of MRD in identifying patients unlikely to be cured by RT, for whom an immunotherapy-based consolidation could improve outcome. Methods 110 patients with stage I/II FL were enrolled. IFRT was administered to all patients at a dose of 24 Gy. Peripheral blood (PB) and bone marrow (BM) samples were centralized to the Italian FIL (Federazione Italiani Linfomi) MRD Network of EuroMRD-certified laboratories: the presence of a BCL2/IGH rearrangement was investigated at baseline in all patients by nested PCR (NEST) and RQ-PCR (RQ), the latter according to the EuroMRD guidelines. In patients BCL2/IGH+ at baseline by both NEST and RQ in BM and/or PB, MRD was analyzed in both tissues after IFRT and every 6 months over a three-year follow-up period. Patients with positive MRD by both NEST and RQ in BM and/or PB after IFRT or who became positive during the follow-up were treated with 8 weekly doses of the anti-CD20 MoAb ofatumumab. The primary objective of the study was to define the efficacy of immunotherapy in obtaining the disappearance of BCL2/IGH rearranged cells. Results Preliminary data are available for 107 patients, 57 males, 50 females. Median age was 55 years (29-83). 17% had G1 FL, 32% G2, 40% G3A, 11% NOS. The FLIPI score was 0 in 59% of patients, 1 in 35%, 2 in 6%. 69% of patients had inguinal site involvement. Despite a negative BM biopsy, at baseline 30% of patients (n=32) had a BCL2/IGH rearrangement (30 MBR, 1 MBR and mcr, 1 mcr) in the BM and/or PB; the concordance between compartments was 90%, with 10% of negative PB showing a positive BM. No significant differences were observed in relapse probability between patients with or without a molecular marker. All patients were submitted to IFRT and all obtained a clinical response, which was complete in 79 of the 101 evaluated patients (78%) and partial in 22 (22%). MRD evaluation after treatment revealed the persistence of BCL2/IGH rearranged cells in the PB and/or BM in 60% of patients. According to the design of the protocol, MRD-positive patients, either after IFRT (n=18) or in case of conversion to a positive signal during the follow-up (n=7), received 8 weekly administration of ofatumumab. A conversion to MRD negativity, evaluated in 23 treated patients, was obtained in 20 (87% - CI 65.1-97.1). This result was significantly superior to the expected 50%. One death occurred after IFRT, due to ischemic stroke. Adverse events likely correlated to ofatumumab occurred in 7/25 treated patients, consisting of infusion reactions in 5, leading to a permanent interruption of immunotherapy in 3. After a median follow-up of 18 months, all patients who achieved a MRD negativity with ofatumumab underwent a regular molecular follow-up and are still MRD-negative. Overall, clinical relapse or progression were observed in 17 patients: 13 (18%) among the 73 "no marker" patients; 2 relapses (16%) were observed among the 12 MRD-negative patients after IFRT and 2 relapses were observed among the 23 patients treated with the anti-CD20 MoAb (8.7%), 1 having achieved a MRD negativity and 1 not. No significant differences in event-free survival have so far been observed between the three groups. Conclusions The MRD data of this phase II trial for early stage FL indicate that RT alone is often insufficient to eradicate the disease, being capable of inducing a negative MRD only in 40% of evaluable cases, with a long-lasting effect only in half of them. The primary objective of this study - MRD negativity after immunotherapy - was achieved, obtaining the disappearance of BCL2/IGH rearranged cells in the majority of patients treated with ofatumumab. The strategy of an immunotherapy consolidation after IFRT in MRD-positive patients allowed to increase molecular responses. A longer follow-up and further studies on larger patient populations will allow to conclusively define the impact of this MRD-driven strategy also on clinical outcome.

Abstract: Introduction. The fludarabine, cyclophosphamide, rituximab (FCR) regimen is associated with high complete response (CR) rates and a negative residual disease status in a significant proportion of cases and is considered the optimal front-line treatment for fit patients with chronic lymphocytic leukemia (CLL). In addition, long-term follow-up of patients treated with FCR at the MD Anderson Cancer Center, in the multicenter German CLL8 study and at Italian institutions indicate that a sizable fraction of patients characterized by a favorable biologic profile remains free from progression in excess of 10 years. FC combined with ofatumumab (FC-O), a human monoclonal antibody which targets an epitope of the CD20 molecule, has also been associated with a high CR rate. The aim of this study was to evaluate whether a double dose of ofatumumab (O2) combined with FC could improve the CR rate in young (≤65 yrs) and fit patients with CLL. Methods. Sixty-one fit CLL patients from 15 Italian institutions were enrolled in this front-line study and treated with the FC-O2 regimen based on the FC schedule (F 25 mg/sqm i.v. d1-3, C 250 mg/sqm i.v. d1-3) combined with 13 doses of O (300 mg i.v. d14; 1000 mg d21 at the first cycle; 1000 mg d1 and d15 at cycles 2-6 and d28 at cycle 6). As infection prophylaxis, patients received bactrim and peg-filgrastim in order to prevent granulocytopenia. CLL diagnosis, treatment requirement and response were assessed according to the 2008 iwCLL guidelines. Minimal residual disease (MRD) was evaluated by flow cytometry in the peripheral blood (PB) and bone marrow (BM), and also by RQ-PCR in flow negative cases. CT scan evaluation was included in the response assessment. Adverse events (AEs) were graded according to the NCI-CTCAE. Results. The median age of patients was 60 years (range 36-65), Binet stages B and C were recorded in 86% of cases, B-symptoms in 21%, increased β2M values in 74% and bulky nodes (≥5 cm) in 10%. An IGVH unmutated status was recorded in 60% of cases, deletion 13q in 37%, no aberrations in 33%, deletion 11q in 14%, trisomy 12 in 12%, 17p deletion and/or TP53 mutation were found in 10% of cases. At present, the median follow-up of patients is 7 months (range 1-20). Response to treatment has been assessed in 29 patients after a median number of 6 courses of treatment (range 2-6). The overall response rate is 90%, with a CR rate of 69% (20 patients). No evidence of MRD was observed by flow cytometry in both PB and BM in 15/20 CR patients (75%). To date, 11 patients with cytometric MRD negative CR have been evaluated by RQ-PCR and no residual disease was detected in 3. Grade 3-4 granulocytopenia was recorded in 4 patients (7%), a severe infection in 4 (7%) and 5 patients (8%) experienced a severe infusion-related reaction during ofatumumab administration. Treatment was discontinued in 8 patients as a result of toxicity (infection, 2 cases; FUO, 1; infusion-related toxicity, 1; autoimmune hemolytic anemia, 1; recurrent granulocytopenia, 1; tachyarrhythmia, 1; non-specified toxicity,1). A non-treatment-related death (traumatic aortic transaction due to a dislocated aortic endoprostheses) has been recorded in a patient after 2 months from treatment discontinuation and 1 showed a disease progression after 4 courses of FC-O2. Conclusions. Taken together, the first analysis of this ongoing front-line study suggests that the combination of FC with an increased dose of ofatumumab is well tolerated with acceptable and no unexpected toxicity. Our preliminary results show that the FC-O2 treatment is associated with a high rate of cytometric MRD-negative CR in young and fit patients with previously untreated CLL.

Abstract: Background: the Registro Italiano Trombocitemie (RIT) was activated mainly to evaluate the diagnosis and therapy appropriateness in the thrombocythemic patients with Ph-negative myeloproliferative neoplasm (MPN) observed in the adhering centers. Objective: to evaluate how the diagnostic and therapeutic approach changed in the RIT patients diagnosed with thrombocythemic MPN in the last two decades. Methods: the RIT centers registered by a web-based system during the years 2005-2014 their thrombocythemic MPN patients, and semesterly updated their follow-up data. For patients diagnosed before 2005, the data on diagnosis and prior follow-up were retrospectively collected. The diagnostic process and the initial treatment (started into the first year after diagnosis) were comparatively analyzed in the patients diagnosed before and after 2005. Results: the RIT centers registered 2629 patients. 2388 of them, object of this analysis, were diagnosed between1995 and 2014: 1098 (46%) in the decade 1995-2004 (Group I), and 1290 (54%) in the decade 2005-2014 (Group II). The diagnostic process in the patients of Group II and Group I included bone marrow biopsy (BMB, performed into 1 year and before any cytoreduction): 85% vs 80%, p 〈 0.001; clonality tests (JAK2 and/or others): 80% vs 9%, p 〈 0.001; cytogenetic evaluation: 55% vs 57%, p 0.58; abdominal echography: 46% vs 41%, p 0.016. The patients of Group II, as compared with those of Group I, showed a similar gender distribution (M/F ratio 0.61 vs 0.65, p 0.452), and had at diagnosis: a higher age (median 60 vs 57 years, p 〈 0.001; age 〉 60 years in 50% vs 45% of cases, p 〈 0.01); a similar rate of prior thrombosis (19% vs 19%), prior hemorrhage (3% vs 4%), CVRFs 69% vs 66%), splenomegaly (25% vs 25%), and hepatomegaly (22% vs 24%); a lower rate of disease-related symptoms (36% vs 40%, p 0.04); a higher rate of comorbidities (55% vs 51%, p 0.03). Moreover, they had: a lower platelet (PLT) count (median 737 vs 775 x 109/L, p 〈 0.001; 〈 600 x 109/L in 22% vs 14% of cases, p 〈 0.001); a similar white blood cell (WBC) count (median 8.6 vs 8.5 x 109/L; 〉 10 x 109/L in 28% vs 26% cases); a similar median levels of hematocrit (HCT %, in females 41.4 vs 41.0; in males 44.7 vs 44.6) and hemoglobin (Hb g/dL, in females 13.8 vs 13.6; in males 15.0 vs 14.9). The BMB, revised according to the WHO 2008 criteria, showed a not different distribution (p 0.21) of ET (64% vs 61%), ep-PMF (16% vs 17%), PMF (3% vs 2%), PV (4% vs 4%), and U-MPN (13% vs 16%. The JAK2 V617F mutation in patients of Group II (at diagnosis) and of Group I (after diagnosis) was found in 62% and in 58% of tested cases (p 0.054), respectively. The patients at high standard thrombotic risk were 58% vs 52%, p 0.004. In the patients of Group II and Group I the distribution of the treatment started into the first year was significantly different (p 〈 0.001): AntiPLT 29% vs 24%, CYT 13% vs 16%, CYT+AntiPLT 49% vs 46%, CYT ± AntiPLT 62% vs 62%, AntiPLT ± CYT 78% vs 69%. The treatment CYT ± AntiPLT was started in the patients at high standard thrombotic risk with a rate of 81% vs 80%, respectively, and in the patients at low standard thrombotic risk in 37% vs 43% of cases, respectively. The initial treatment CYT±AntiPLT was related, in multivariate analysis, both in patients of Group II and Group I, with older age ( 〉 60 and 40-60 vs 〈 40 years, p 〈 0.001), higher PLT count ( 〉 1000 and 700-1000 vs 〈 700 x 109/L, p 〈 0.001), prior thrombosis (p 〈 0.001), symptoms (p 〈 0.001). Noteworthy, no relationship was found with JAK2 mutation, and WHO diagnosis. Conclusion: in the studied thrombocythemic MPN patients the real-life diagnostic approach was improved after 2005 not only due to the routine use of JAK2 tests, but also due to the higher rate of BMB done (85% vs 80%). The appropriateness of the cytoreductive treatment (CYT±AntiPLT started into one year from diagnosis) remained high in patients at high standard thrombotic risk (over 80% of cases were treated). Concomitantly, the inappropriate use of the cytoreductive drugs in patients at low standard thrombotic risk appreciably decreased (from 43% to 37% of cases). Moreover, it has to be remarked that the therapeutic approach was significantly influenced not only by older age and prior thrombosis, but also by thrombocytosis (PLT count 〉 700 x 109/L), disease-related symptoms, and inconstantly by leukocytosis and CVRFs.

Abstract: Background: Proteasome inhibitor (PI)-based induction and consolidation proved to be effective in newly diagnosed multiple myeloma (NDMM) patients (pts) eligible for melphalan 200 mg/m2-autologous stem cell transplant (MEL200-ASCT). High response rates have been reported with the second-generation PI Carfilzomib in combination with Lenalidomide-dexamethasone (KRd) or Cyclophosphamide-dexamethasone (KCd). Aims: The primary aim was to evaluate the efficacy and safety of KRd induction-ASCT-KRd consolidation (KRd-ASCT-KRd) vs 12 cycles of KRd (KRd12) vs KCd induction-ASCT-KCd consolidation (KCd-ASCT-KCd). Methods: NDMM pts ≤65 years were randomized (1:1:1; stratification ISS and age) to: KRd-ASCT-KRd: 4 28-day cycles with KRd induction (Carfilzomib 20/36 mg/m2 IV days 1,2,8,9,15,16; Lenalidomide 25 mg days 1-21; dexamethasone 20 mg days 1,2,8,9,15,16) followed by MEL200-ASCT and 4 KRd consolidation cycles; KRd12: 12 KRd cycles; KCd-ASCT-KCd: 4 28-day induction cycles with KCd (Carfilzomib 20/36 mg/m2 IV days 1,2,8,9,15,16; Cyclophosphamide 300 mg/m2 days 1,8,15; dexamethasone 20 mg days 1,2,8,9,15,16) followed by MEL200-ASCT and 4 KCd consolidation cycles. Thereafter, pts were randomized to maintenance with Lenalidomide alone or plus Carfilzomib. Centralized minimal residual disease (MRD) evaluation - 8-color second generation flow cytometry, sensitivity 10-5 - was performed in pts achieving ≥very good partial response (VGPR). Endpoints were pre-maintenance stringent complete response (sCR) and MRD negativity in intention-to-treat (ITT) analysis. Data cut-off was May 30, 2018. Results: 474 NDMM pts were randomized (KRd-ASCT-KRd, n=158; KRd12, n=157; KCd-ASCT-KCd, n=159) and analyzed. Pts characteristics were well balanced. Median follow-up was 20 months. Depth of response improved during treatment (Figure). By ITT analysis, rates of pre-maintenance sCR was similar between KRd-ASCT-KRd (41%) and KRd12 (42%), and significantly higher than with KCd-ASCT-KCd (30%; P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.047; P value KRd12 vs KCd-ASCT-KCd=0.028). Similarly, rate of ≥CR was 49% with KRd-ASCT-KRd, 52% with KRd12 and 38% with KCd-ASCT-KCd (P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.041; P value KRd12 vs KCd-ASCT-KCd=0.014) and rate of ≥CR+unconfirmed CR (missing immunofixation confirmation) raised to 60% vs 63% vs 46% in the 3 groups, respectively; rate of ≥VGPR was 88% with KRd-ASCT-KRd, 86% with KRd12 and 74% with KCd-ASCT-KCd (P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.002; P value KRd12 vs KCd-ASCT-KCd=0.008). In multivariate analysis, the main factor affecting probability of achieving ≥VGPR, ≥CR or sCR was treatment with KRd-ASCT-KRd or KRd12 vs KCd, with no significant impact of ISS Stage or FISH abnormalities. In ITT analysis (MRD missing [31/395 VGPR pts, 8%] and 〈 VGPR were considered as MRD positive), MRD negativity was again similar with KRd-ASCT-KRd (58%) and KRd12 (54%) and significantly higher than with KCd-ASCT-KCd (41%; P value KRd-ASCT-KRd vs KCd-ASCT-KCd=0.004; P value KRd12 vs KCd-ASCT-KCd=0.023); 82% vs 78% vs 88% of pts in the 3 groups, respectively, could maintain extended MRD negative status with 2 MRD negative results obtained apart ≥6 months (either pre-ASCT and post consolidation or post consolidation and during maintenance). During treatment (excluding ASCT) the most frequent grade 3-4 AEs were neutropenia (KRd-ASCT-KRd 20%, KRd12 10%, KCd-ASCT-KCd 16%), thrombocytopenia (KRd-ASCT-KRd 15%, KRd12 8%, KCd-ASCT-KCd 13%) and infections (KRd-ASCT-KRd 14%, KRd12 12%, KCd-ASCT-KCd 13%). Grade 3-4 dermatologic AEs (KRd-ASCT-KRd, 5% with KRd12 12%, KCd-ASCT-KCd 1%), increase in liver enzymes (KRd-ASCT-KRd 9%, KRd12 10%, KCd-ASCT-KCd 1%) and hypertension (KRd-ASCT-KRd 3%, KRd12 8%, KCd-ASCT-KCd 3%) were more frequent with KRd12. Rates of grade 3-4 cardiac AEs (KRd-ASCT-KRd 3%, KRd12 2%, KCd-ASCT-KCd 4%) and thrombosis (KRd-ASCT-KRd 1%, KRd12 2%, KCd-ASCT-KCd 2%) were below 5% in all arms. Discontinuation for AEs was similar in the 3 arms (KRd-ASCT-KRd 6%, KRd12 8%, KCd-ASCT-KCd 7%). Conclusions: Rates of MRD negativity, sCR, ≥CR, ≥VGPR were significantly higher with KRd-ASCT-KRd and KRd12 vs KCd. At present, no differences in MRD and overall best response (sCR, ≥CR, ≥VGPR) were noticed between KRd-ASCT-KRd and KRd12; longer follow-up is needed to evaluate survival. Treatment was well tolerated. Updated data will be presented at the meeting. Figure. Figure.

Abstract: Introduction: Multiple myeloma (MM) is still an incurable disease and patients may relapse despite achievement of complete remission (CR). Minimal residual disease (MRD) assessment by multiparameter flow cytometry (MFC) on bone marrow (BM) is a sensitive diagnostic tool to measure response and is highly predictive of outcome in MM as previously reported. The aim of this study is to evaluate the role of MRD monitoring by MFC in MM patients receiving novel agents with or without autologous stem cell transplantation (ASCT) and to investigate the efficacy of treatments by using MRD-negativity as a deeper response criteria. Methods: The RV-MM-COOP-0556 (EMN02/HO95 MM) study is a phase III, randomized, trial including newly diagnosed MM patients ≤ 65 years. All subjects received 4 cycles of Bortezomib-Cyclophosphamide-Dexamethasone (VCD) induction, followed by Cyclophosphamide chemotherapy and subsequent stem cell mobilization and collection. Afterward, patients were randomized to receive 4 cycles of Bortezomib-Melphalan-Prednisone (VMP) vs one or two cycles of High-Dose-Melphalan (HDM) followed by ASCT. After intensification patients were secondly randomized to receive two cycles of consolidation with Bortezomib-Lenalidomide-Dexamethasone (VRD) vs no consolidation, followed by Lenalidomide maintenance in both arms. Patients who achieved CR/sCR according to IMWG criteria (Rajkumar et al. Blood 2011) after intensification/consolidation treatment, were eligible for the MRD sub-study. MRD analysis by MFC was performed on BM samples after intensification/consolidation, after 6 courses of maintenance, and thereafter every 6 months until progression, to detect monoclonal plasma cells (PCs). Here, we used a double antibody combination (CD138Fitc/CD20PerCp-Cy5.5/CD117APC/CD45APC-H7/CD38PE-Cy7; cyKappaFitc/cyLambdaPE/CD19PerCp-Cy5.5/CD56APC/CD45APC-H7/CD38 PE-Cy7): one tube was employed to obtain PCs quantification, the other one to validate PCs clonality. MRD-negativity was defined when 〈 20 clonal PCs were detected among ≥2.000.000 leukocytes ( 〈 0.001%). Results: One hundred-eleven Italian patients (58 male/53 female) with a median age of 56 years (IQR 52-62) entered MRD sub-study. Sixteen (14%) were ISS stage III, 24 (22%) had high-risk cytogenetic profile and 10 (9%) had LDH levels higher than the upper normal limit. Forty-five patients (40%) received VMP as intensification and 66 (60%) underwent ASCT, thereafter 65 (58%) received VRD consolidation, 24 after VMP and 41 after ASCT. The median follow-up were 28.7 and 17 months from starting treatment and from MRD enrollment, respectively. After intensification/consolidation, 4 patients were not evaluable for MRD due to unsuitable samples, MRD negativity rate was 79% (85 out of 107 evaluable patients) and was independent from the intensification therapy: actually 50/63 patients who received ASCT and 35/44 patients who received VMP achieved MRD negativity. Within MRD-negative patients, 48/85 (56%) received VRD consolidation without major differences between VMP and ASCT. With the limitation related to the shorter follow-up, depth of response further improved during maintenance: 11/22 (50%) of MRD-positive patients became MRD-negative, independently from previous intensification therapy. Conclusions: MRD detection by MFC is a feasible technique in MM and allows to detect residual tumor cells among CR and sCR patients. Preliminary MRD results show that, in patients achieving CR, intensification with VMP or ASCT induced comparable rates of MRD-negativity and maintenance with Lenalidomide further improved depth of response in both arms. Longer follow-up is needed to correlate MRD status to prognosis and clinical outcome and to evaluate the role of maintenance therapy in increasing the quality of response.

Abstract: Splenectomy in addition to immunotherapy with rituximab can provide quick and sometimes durable disease control in patients with splenic marginal zone lymphoma (SMZL). However, systemic chemotherapy is ultimately required in many cases. The BRISMA (Bendamustine‐rituximab as first‐line treatment of splenic marginal zone lymphoma)/IELSG (International Extranodal Lymphoma Study Group)36 trial is an open‐label, single arm phase II study designed by the IELSG in cooperation with the Fondazione Italiana Linfomi and the lymphoma Study Association according to Simon's two‐stage method. The primary endpoint was complete response rate. Fifty‐six patients with SMZL diagnosis confirmed on central revision were treated with bendamustine (90 mg/m 2  days 1, 2) and rituximab (375 mg/m 2  day 1) every 28 days for six cycles (B‐R). The overall response and CR rates were 91% and 73%, respectively. Duration of response, progression‐free survival and overall survival at 3 years were 93% (95% confidence interval [CI] 81–98), 90% (95% CI 77–96) and 96% (95% CI 84–98), respectively. Toxicity was mostly haematological. Neutropenia grade ≥3 was recorded in 43% of patients; infections and feb rile neutropenia in 5·4% and 3·6%. Overall, 14 patients (25%) experienced serious adverse events. Five patients (9%) went off‐study because of toxicity and one patient died from infection. In conclusion, B‐R resulted in a very effective first‐line regimen for SMZL. Based on the results achieved in the BRISMA trial, B‐R should be considered when a chemotherapy combination with rituximab is deemed necessary for symptomatic SMZL patients.
