Abstract: Introduction: Rituximab is a monoclonal antibody commonly used in B-DLCL both in salvage regimens and in combination with first-line chemotherapy. Some studies have reported delays in neutrophil or platelet engraftment after ASCT in patients treated with high dose chemotherapy and Rituximab prior to ASCT. We investigated the effect of adding Rituximab prior to ASCT on peripheral blood stem cell (PBSC) harvest, time to engraftment and short-term toxicity post ASCT. Patients and methods: We analyze stem cell mobilization, engraftment (median time to absolute neutrophil count & gt; 500/mm3 for three consecutive days and platelets & gt; 50.000) and short-term toxicity after ASCT ( & lt; 30 days) in two groups of patients affected by B-DLCL at diagnosis enrolled into two consecutive trials with or without Rituximab in combination with chemotherapy. All patients were & lt; 61 years with B-DLCL at age-adjusted IPI Intermediate-High (IH) or High (H) risk and/or with bone marrow (BM) involvement. Group A: an intensified chemoimmunotherapy regimen R-MegaCEOP (Rituximab 375 mg/m2 day 1, CTX 1200 mg/m2 + EPI 110 mg/m2 + VCR 1.4 mg/m2 day 3 and PDN 40 mg/m2 days 3 to 7) every 14 days with G-CSF support for 4 courses; patients in complete response (CR) or partial response (PR) received two courses of intensified chemotherapy R-MAD (Mitoxantrone 8 mg/m2 + ARA-C 2000 mg/m2/12h + Dexamethasone 4 mg/m2/12h days 1 to 3 and Rituximab 375 mg/m2 day 4 and before PBSC harvest). Group B: MACOP-B 8 weeks + 2 courses of MAD (in patients in CR or PR) without Rituximab. Both groups were given ASCT with BEAM as conditioning regimen. Clinical characteristics at diagnosis were well balanced between the two groups. Results: 68 patients are evaluable: 35 pts in group A (with Rituximab) and 33 pts in group B (without Rituximab). All patients in both groups collected more than 2 x 106 CD34+ cell/kg. Median CD34+ cell/kg in group A was 13 x 106 (range 0-37) compared with 41 x 106 in group B (range 0–253) with no statistically significant difference. Median time to neutrophils engraftment after ASCT was similar in the two groups: 9 days in group A and 10 days in group B. No delay in the platelet recovery was observed in patients treated with chemoimmunotherapy: 15 days in group A vs 16 days in group B. Few severe early toxicities (WHO grade 3–4) were reported with no differences between group A vs B: severe mucositis in 11 pts vs 23 pts, gastrointestinal in 6 pts vs 4 pts. Severe infections occurred in 10 patients: group A 6 patients (2 Gram+ sepsis, 1 Gram- sepsis, 1 FUO, 2 bacterial pneumonia); group B 4 patients (2 FUO, 1 bacterial and 1 viral pneumonia). One patient in group A died of bacterial pneumonia after ASCT. Conclusions: Treatment with Rituximab may be safely included in a pre-ASCT high dose chemotherapy regimen with no delay in stem cell harvest, engraftment and without increased early toxicity after ASCT.

Abstract: Background. Chronic Myeloid Leukaemia (CML) can be effectively treated with the first generation Tyrosine Kinase Inhibitor (TKI) Imatinib, and more effectively with the second generation TKI, like Nilotinib. However, despite the deeper and faster responses induced by nilotinib in a large proportion of patients, the possible eradication of the pathological stem cells is not yet clearly elucidated. In fact, in vitro data suggest that quiescent stem cells are not sensitive to Bcr/Abl inhibition (Corbin AS, et al 2011; Hamilton A, et al 2012). A preliminary in-vivo study (Defina M, et al 2012) shows that in patients in CCyR even after short-term of nilotinib therapy, residual leukemic progenitors are rarely detected. Methods. On behalf of Rete Ematologica Lombarda (REL), Italy, we designed a single arm prospectic study, PhilosoPhi34 (EudraCT: 2012-005062-34), with the aim to investigate the efficacy of nilotinib 300 mg BID in obtaining the disappearance of Bone Marrow (BM) leukemic stem cells (CD34+/lin-Ph+) in newly diagnosed CP-CML. Primary objective of the study: to enumerate the BM CD34+/lin-Ph+ cells at the end of 6 months of treatment. Secondary objectives: to enumerate the BM CD34+/lin-Ph+ cells at 3 and 12 months; to assess the percentage of patients showing MR ≤10% IS at 3 months and MR ≤1% IS at 6 months and the MMR IS and MR4.5 IS by 3, 6 and 12 months of treatment. BM blood samples (range of 5-20 ml) were collected at diagnosis and after 3, 6 and 12 months of nilotinib treatment. BM mononuclear cells were purified by density gradient centrifugation and then CD34+/lin- cells were isolated using Diamond CD34 Isolation Kit (Miltenyi Biotec). The purity of CD34+/lin- cells was about 97% as determined by flow cytometry. BM CD34+/lin- cells were counted and a range of 100,000-800,000 has been noted at diagnosis. After the treatment we observed that the number of CD34+/lin- cells dramatically decreased after 3 (1,000-600,000), 6 (1,000-260,000) and 12 months (100-130,000). In particular, CD34+/lin- cells were even less than 1000 at 12 month of treatment. In order to verify the disappearance of leukemic stem cells, isolated CD34+/lin- cells were tested by standard FISH (i.e. to categorize a sample as negative at least 200 nucleus were examined). From April 2013 and June 2015 we enrolled 87 pts, as for protocol. We report here the preliminary results. Results. Of 56 patients in CCyR after 6 months of treatment, FISH performed on BM CD34+/lin- cells nuclei was evaluable in 51 cases (5 negative cases were excluded because of less than 200 nucleus were analysed). In 4 out of 51 patients (7.8%), Ph+ nuclei were detected. The Sokal score of these 4 patients was 1 low, 2 intermediate and 1 high risk with a ratio (positive nuclei/total nuclei) of 295/300, 1/200, 2/92, 3/300, respectively. Among 58 patients tested at 3 months and 44 tested at 12 months of treatment, the number of evaluable patients was 48 and 37, respectively; 8/48 (16.6%) and 0/37 (0%) patients showed Ph+ nuclei. Only 2 out of 8 positive patients had a high Sokal score. Regarding efficacy of treatment, Table 1 summarizes the MRs IS observed after 3, 6 and 12 months of treatment in 71, 57 and 41 patients, respectively. Conclusion. Data of this prospective study confirms that nilotinib 300 mg BID, rapidly and progressively induces the clearance of BM CD34+/lin-Ph+ cells in CP-CML patients. In particular, on CD34+/lin- cells, after 6 months of treatment, only 7.8% of patients showed positive nuclei. On 37 patients after 12 months of treatment, no positive nuclei were detected. So far, the kinetic of reduction of such cells seems not influenced by Sokal score. According to international studies, PhilosoPhi34 shows a very high efficacy of Nilotinib to induce MRs in CP-CML patients, at the standard time points. Table 1.

Abstract: Background: The role of bone marrow response in patients with immune thrombocytopenia (ITP) has gained paramount importance since the last 10 years, with the demonstrations that marrow megakaryocytes (MGK) are unable to properly compensate platelets peripheral destruction. TPO receptor agonists (TPOa), namely romiplostim (ROMI) and eltrombopag (EPAG), by stimulating megakaryopoiesis are able to induce a response in 74% to 94% of cases in clinical trials. However, real world use of these drugs has shown frequent changes in individual dose requirement, the possibility of treatment discontinuation, and their effectiveness outside registered indications; moreover, nothing is known about predictors of response. Aim: To evaluate clinical and morphologic predictors of response in a real world cohort of ITP patients treated with TPOa. Methods: ITP patients treated with EPAG and ROMI from September 2009 to May 2018 at seven Italian Centers were evaluated. Clinical and hematologic parameters including treatment response and marrow characteristics were retrospectively collected. Results: Table 1 shows baseline clinical and morphologic characteristics for the 86 cases enrolled, altogether and divided according to the TPOa used: patients were mainly middle-aged females presenting with severe thrombocytopenia; anti-PLT autoantibodies were positive in 32.6% of cases, and 58.1% of cases presented with bleeding, 22% of grade III-IV. All cases had received 1st line treatment with steroids and 43% at list a 2nd line among those listed in Tab1. Pre-TPOa marrow evalutation showed hypocellularity in 30.2% of cases, reticulinic fibrosis in 33.7%, a polyclonal lymphoid infiltrate in 43% (mostly mixed or T-cell), and reduced MGK in 4.7% of patients. Some dysplastic features were present in about 50% of cases, either dysmegakaryopoiesis (46.5%) or dyserythropoiesis (25.6%). Median time from diagnosis to TPOa was 2.4 years (0.1-28.8). Patients were treated for a median of 1.4 years (0.3-10.8), and ORR at 3 months and 9 months were 75.6% (CR 44.2 and PR 31.4%) and 65.1% (CR 36 and PR 29.1%), respectively. Response rates to EPAG and ROMI were comparable. Regarding predictors of response, bone marrow hypocellularity (40 NR vs 21% ORR, p=0.05) and megakaryocytopenia (33 vs 6%, p=0.06) were significantly more frequent among NRs. Other factors associated with poor response were dyserythropoiesis (58 vs 26%, p=0.04) and erythroid hyperplasia (18 vs 8%, p=0.03), and presence of a T cell infiltrate (66 vs 18.9%, p=0.03). Finally, NRs cases showed significantly lower neutrophil counts at baseline (1.9 vs 2.3x103/mmc in ORR, p=0.01), and had been more frequently exposed to cyclosporine or azathioprine (50 vs 18% in ORR, p=0.01). Fifty-five patients are still on treatment, whereas 31 (20 EPAG/11 ROMI) discontinued because of NR or relapse (17), adverse events or intolerance (2); of note, 12 patients with ORR discontinued the drug because of sustained CR, and 7 of them are still in remission. 14/65(21.5%) responding cases (10 EPAG/4 ROMI) lost the response after a median of 6.2 months (1.8-60) and were variably managed (3 splenectomized, 1 switched from ROMI to EPAG, 1 received danazol, 5 were re-treated with EPAG, and the remaining were managed with steroids and supportive treatment). Median RFS was 2.3 years (0.1-10), longer in patients without megakaryocytopenia (9.9+0.5 vs 4.1+0.6, p=0.06), dyserythropoiesis (mean 9.1+0.5 vs 4.9+0.7, p=0.2), and reticular fibrosis (9.6+0.5 vs 5.5+0.6, p=0.08). During EPAG treatment 7 grade adverse events occurred: 2 grade IV (1 stroke with PLT counts of about 30x103/mmc, and 1 NSTEMI 1 month after EPAG discontinuation for sustained CR), 1 grade III pneumonia, and 4 grade I/II transaminase elevation. No events occurred under ROMI. Conclusions: TPOa use in the real world setting confirms their reported efficacy, the option to switch and/or re-treat with either EPAG or ROMI, and the possibility to discontinue the drugs. The presence of hypocellularity and megakaryocytopenia, along with dysplastic features and of a lymphoid T cell infiltrate are associated with a reduced response to TPOa and a shorter RFS. Pre-treatment bone marrow evaluation may give hints to unravel the physiopathologic mechanisms underlying TPOa refractoriness.

Abstract: INTRODUCTION We retrospectively analyzed the impact on post-relapse survival of selected prognostic factors and salvage therapy (finalized to perform an allo-SCT) in 145 patients (pts) with non-APL AML who had been initially treated with standard induction and risk-adapted consolidation. The aim was to identify factors associated with a better outcome at first relapse. METHODS All pts were at first recurrence following consolidation of CR1 with (i) high-dose Ara-C (HiDAC) multicycle therapy supported by blood stem cells (standard risk, as defined by mixed clinico-cytogenetic criteria) or (ii) allo-SCT in case of high-risk prognostic profile. Median pt age was 55 y (range 21–68). CR1 duration was ≤ 6 months in 49 pts (34%), ranging from 0.6 to 6 mo (median 3.7). 25/68 pts (37%) had an unfavourable cytogenetics (CG), and 8.2 % had MDS-related AML. 96 pts (66%) had received HiDAC and 21 (15%) an allo-SCT according to study design. RESULTS 105 pts (72%) received salvage chemotherapy, 10 pts (7%) underwent directly allo-SCT, while the remaining 30 (21%) received palliation and all of them died. Salvage therapy consisted again of HiDAC alone or in combination with fludarabine or anthracyclines. After reinduction, 52/105 pts (49.5%) achieved CR2 and 15 (14%) died of complications. Altogether, 42 pts (29%, group 1) received an allo-SCT following relapse, 27 (64%) in CR2, 5 beyond CR2 and 10 soon after relapse. Of 20 more pts (14%, group 2) in CR2 but without HLA identical donor, 13 could be given further intensive consolidation therapy. Both groups were comparable regarding adverse prognostic features such as age 〉 55 y, WBC count 〉 50,000/μL, unfavourable CG, presence of FLT-3 ITD, prior allo-SCT and 1st CR lasting ≤ 6 mo. At the end of treatment, 37/42 pts (88%) receiving SCT and all 20 pts (100%) given only chemotherapy were in CR2. Logistic regression analysis showed that intensive treatment without HiDAC at induction (p=0.04) as well as CR1 lasting 〈 6 mo (p=0.01) negatively affected CR2 rate. Median duration of CR2 was 7.5 mo (range 1–49) in group 1 compared to 4 mo (range 1–15) in group 2. Day 100 non-relapse mortality in the 2 groups was 7% and 10%. After a median follow-up of 9.4 mo in group 1 (range 3–49) and 10 mo in group 2 (range 2–65), 2-y OS was 24% and 15.5%, respectively. Notably, 2-y OS in allo-SCT group ranged from 42% in pts ≤ 45 years to 14% in older ones. Moreover, survival was affected by risk category. In fact 2-y OS of 14/37 (38%) standard risk pts undergoing allo-SCT at salvage was 41% vs 17% in 28/108 (26%) comparable high risk pts. Cox regression analysis revealed achievement of CR2 being the only independent prognostic factor related to overall survival (p=0.0001). CONCLUSIONS AML patients receiving intensive chemotherapy including HiDAC at 1st relapse reached a high CR2 rate, regardless of type of prior risk-adapted consolidation. Further intensification with allo-SCT may offer substantial salvage rates to younger standard risk patients, thus adding value to the underlying concept of a risk-oriented first-line therapy.

Abstract: INTRODUCTION The impact on post-relapse survival of selected prognostic factors and salvage therapy (finalized to perform an allo-SCT) was retrospectively analyzed in 172 patients (patients) with relapsed non-APL AML, who had been initially treated with standard induction and risk-adapatiented consolidation. The aim was to identify factors associated with a better outcome at first relapse. METHODS All 172 patients were at first recurrence following consolidation of CR1 with high-dose Ara-C (HiDAC) multicycle therapy supported by blood stem cells (standard risk, as defined by mixed clinical-cytogenetic criteria) or allo-SCT in case of high-risk prognostic profile. Median age at relapse was 55 y (range 21–70). CR1 duration was & lt;6 months in 50 patients (29%), ranging from 0.6 to 52,7 mo (median 9,1). High risk patients were 128/172 (74%) and 43/172 patients (25%) had an unfavourable cytogenetics (CG). One hundred-eleven patients (64%) received HiDAC and 24 (14%) an allo-SCT according to study design. RESULTS 140 patients (81%) received salvage treatment. The remaining 32 patients (19%) received palliation and all of them died. The median OS was 17.1 mo, with a 2yOS of 34%. Favorable prognostic factors identified by univariate analisys were: favourable or intermediate CG (p=0,007), standard risk category according to first line protocol (p=0.004), availibility of a HLA matched donor (p= 0.048), achievement of an early CR1(p=0,000), HiDAC as first line therapy(p=0,000), alloHSCT perfomed at relapse (p=0,000) and a DFS from CR1 & gt;12 mo (p=0,000). In multivariate analysis favourable or intermediate CG and DFS & gt;12 mo were confirmed as independent prognostic factors (p=0,036 and p=0,001 respectively). Among the 140 patients, 50 received an allo-SCT following relapse (36%, group 1), and the remaining 90 (64%, group 2) received high dose chemotherapy alone (85), autologous SCT (2), or DLI (3, in case of previous alloSCT). Both groups were comparable regarding age & gt;55 y, prior allo-SCT and risk class at diagnosis. After salvage therapy, 44 patients(88%) in the group 1 achieved CR2, compared to 26 patients (29%) in the group 2. The median duration of CR2 was 9 mo (range 2–64) and 3 mo (range 1–34) in group 1 and 2 respectively. NRM was 17/140: 12 patients (24%) in the allo-SCT group and 5 (6%) in group 2. The 2yOS was 57% and 23% respectively (p=0,000). Moreover, among 50 alloSCT patients, survival was affected by risk category at diagnosis: 2yOS of 19 (38%) standard risk patients was 83% compared to 42% in 31 high risk patients (62%) (p=0.01). This risk stratification has no impact on OS in the group 2. CONCLUSIONS DFS & gt; 12 mo and standard risk category at diagnosis, according to NILG protocol, are the most important independent positive prognostic factors impacting OS of AML relapsed patients. The availibility of a HLA matched donor and a subsequent intensification with alloSCT may offer substantial salvage rates and its outcome is affected by the risk stratification at diagnosis. Nevertheless, high risk patients could benefit from alloSCT, reaching an 2yOS of 42%.

Abstract: Background. Ara-c based chemo-immunotherapy followed by autologous stem cell transplantation (ASCT) is the most effective approach in young mantle cell lymphoma (MCL) patients, though few if any patients are cured. Recent data indicate that subsequent Rituximab maintenance (RM) prolongs PFS and OS (Le Gouill NEJM 2017). Lenalidomide is an oral agent effective in MCL, considered suitable for prolonged maintenance programs, but has never been tested in this setting. The FIL MCL0208 trial (NCT02354313) is a prospective, international randomized, phase III trial, comparing Lenalidomide maintenance (LM) vs observation (OBS) after an intensive Ara-c containing chemo-immunotherapy (R-HDS) program, followed by ASCT in previously untreated MCL patients. Patients and Methods. Adult patients aged 18-65 years, with advanced stage MCL without clinically significant comorbidities were enrolled. Patients received 3 R-CHOP-21, followed by R-HDS i.e. R-high-dose Cyclophosphamide (R-HD-CTX) (4g/m2), 2 cycles of R-high-dose Ara-C (R-HDAC) (2g/m2 q12x3 d). CD34+ cells were collected after the first course of R-HDAC. The conditioning regimen for ASCT was BEAM. After ASCT, responding patients were randomized between LM (15 mg days 1-21 every 28 days) for 24 months or observation. Primary endpoint analysis was scheduled at the occurrence of the 60th PFS event in the randomized population, which occurred on June 20th, 2017 and data were analyzed for the present abstract on March 3rd 2018. Results. Three-hundred three patients were enrolled from May 2008 to August 2015 by 48 Italian and 1 Portuguese Center. Three patients were excluded after central histological review. Median age was 57 years (IQR 51-62), M/F ratio 3.6/1. Ninety-two percent of patients had stage IV, 33% bulky disease ( 〉 5 cm), 33% elevated LDH, and 75% BM infiltration. Ki67 ≥30% was observed in 32%, MIPI was low (L) in 54%, intermediate in 31% and high (H) in 15% of patients. MIPI-c was L in 49%, low-intermediate (LI) in 29%, high-intermediate (HI) in 14%, H in 9%. Nine percent had blastoid variant. Fifty-two (17%) patients interrupted treatment before randomization (8 toxic deaths, 1 death for car accident, 24 progressions and 19 toxicity/refusals). On an ITT basis, the R-HDS + ASCT program induced 78% of CR, 7% of PRs, 10% of PD, 3% of toxic deaths (TRM) and 2% NA. Median follow-up (mFU) from inclusion was 51 months. Three years PFS and OS for the enrolled population were 67% and 84%, respectively. Of 248 patients who received ASCT, 205 were randomized either to LM (n=104) or OBS (n=101) and 43 (17%) were not because of: lack of response (8), refusal/PI decision/delay (8), unresolved infections (3) and inadequate hematopoietic recovery (24). Feasibility and efficacy were assessed on an ITT basis while toxicity was analyzed on subjects receiving at least one Lenalidomide dose. In the LM arm, 53 out of 104 patients did not start or complete the planned maintenance because of death (2), AE (26), PD (7), still ongoing (2), other causes (16). In the OBS arm 32 patients did not complete the observation phase because of death (1), AE (1), PD (20), still ongoing (10), other causes (1). Overall 28% of patients received less than 25% of the planned Lenalidomide dose. Despite suboptimal exposure to study drug, with a mFU from randomization of 35 months, 22 PFS events were recorded in the LM cohort vs 38 in the OBS arm, resulting in a 3y-PFS of 80% (95% CI; 70%-87%) in the LM arm vs. 64% in the OBS arm (95% CI; 53%-73%), stratified HR 0.51; 95% CI 0.30-0.87; p=0.013 (Fig 1A). OS was superimposable in the two arms: 93% vs 86%, stratified HR 0.96, 95% CI 0.44-2.11, p= 0.91 (Fig1B). Two deaths were observed in the LM arm due to pneumonia and thrombotic thrombocytopenic purpura and one in the OBS arm due to pneumonia. Grade 3-4 hematological toxicity was seen in 63% of patients in LM vs 11% in the OBS arm with 59% vs 10% of patients experiencing granulocytopenia. Non-hematological grade 3 toxicity was comparable in the two arms except grade 3-4 infections (11% vs. 4%; Fisher's p=0.10). Second cancers occurred in 7 patients in the LM and 3 in the OBS arm (Fisher's p=0.20). Conclusions. Results from the MCL0208 trial indicate that LM has a clinically meaningful anti-lymphoma activity in MCL. However, the applicability of LM has some limitations in the context of patients undergoing intensified chemoimmunotherapy. Overall these data support the use of a maintenance regimen after ASCT in young MCL patients.
