Abstract Abstract 4024 Background: The hypomethylating agents 5-azacytidine (Vidaza) and 5-aza-2′-deoxycytidine (Decitabine, DAC) are active in different MDS subtypes. Compared to other response predictors to DAC, prior MDS duration has received only limited attention (1, 2), with conflicting results. Based on our finding that long duration of MDS prior to DAC treatment may be a novel factor linked to a better outcome (1), we now assess its value in the phase III trial 06011 (DAC versus BSC [3]). Immediate enrolment after diagnosis was allowed in that trial, median MDS duration prior to randomization thus only 3 months (mths). Methods: Comparison of progression-free (PFS), AML-free (AMLFS) and overall survival (OS) according to MDS duration >= vs. <3 mths in 233 patients (pts) with higher-risk MDS (median age 70 years) randomized to DAC (n=119) or BSC (n=114). Comparisons by long-rank test and multivariate analyses by Cox regression (Performance Status [PS], cytogenetics and IPSS high risk N/Y) were performed retrospectively: MDS duration had not yet been known as possible stratification factor at time of study initiation, and the trial thus not been powered to detect significant differences with regard to this discriminator. Results: A better prognosis of patients with MDS duration >=3 vs <3 mths was observed in DAC arm (B vs A) and BSC arm (D vs C). Conversely, DAC yielded better results than BSC in each MDS duration group: <3 mths (A vs C) and >=3 mths (B vs D). In both arms (n=233), Mult. indicated that MDS duration (>=3 vs <3 mths) adjusted for treatment, PS, cytogenetics and IPSS group was an independent prognostic factor regarding PFS (HR=0.75, 95%CI 0.58–0.99), AMLFS (HR=0.68, 95%CI 0.51–0.90), and OS (HR=0.75, 95%CI 0.56–0.99). The tests for interaction treatment × duration of MDS were not significant for 3 endpoints: PFS (p=0.38), AMLFS (p=0.90), OS (p=0.67). Conclusion: In intermediate-2 and high-risk MDS pts, long duration from MDS diagnosis to start of DAC or BSC appeared to be associated with a better outcome. This finding is in sharp contrast to the adverse prognostic impact of antecedent disease duration in patients who received intensive chemotherapy (4). It is supported by a similar analysis of pts with AML from MDS treated on the 00331 DAC phase II multicenter trial: those with longer MDS duration prior to DAC also had better outcome (5). Application of this discriminator in the evaluation also of other DAC schedules and MDS treatments therefore appears warranted. References: 1. Wijermans et al., Ann.

Abstract BACKGROUND: Genomic aberrations and IGHV mutation status are established prognostic factors in CLL. With TP53, NOTCH1, SF3B1, ATM, MYD88, FBXW7, BIRC3 and POT1 recurrently mutated genes were found in CLL and were discussed to associate with disease characteristics and to affect therapy efficacy and outcome. METHODS: We assessed the incidence and impact of gene mutations in the COMPLEMENT1 trial (1st line Chl vs. O-Chl). Pretreatment samples were available from 376 patients (84.1%) and this cohort was representative of the full trial population. Mutations were analyzed by amplicon-based targeted NGS using Illumina Miseq for all coding exons (TP53, ATM, MYD88, FBXW7, BIRC3 and POT1) or hotspot exons (NOTCH1, SF3B1). Additionally, the exact variant frequency was determined. RESULTS: The incidences of gene mutations were: TP53 8.2%, NOTCH1 14.9%, SF3B1 14.1%, ATM 10.9%, MYD88 2.7%, FBXW7 3.5%, POT1 7.7%, and BIRC3 2.7%. Regarding baseline characteristics, we found significant associations: TP53mut with high ß2MG (p=0.01), 17p- (p<0.01), and unmutated IGHV (p=0.01); ATMmut with high WBC (p=0.02), and 11q- (p<0.01); MYD88mut with mutated IGHV (p=0.02); FBXW7mut with 17p- (p=0.02), and +12q (p<0.01). BIRC3mut was only present in IGHV unmutated cases (p<0.01), was more frequent in 11q- (p<0.01), +12q (p=0.05), and in cases with NOTCH1mut (p=0.05). POT1mut was more frequent in NOTCH1mut cases (p=0.02) without associations with any other baseline parameter. Regarding response to treatment, TP53mut was significantly associated with reduced ORR rate (p<0.01). CR rate was not correlated with mutations in the covered genes. At a median follow-up of 31.7 months, there were 249 (66%) events for PFS and 63 (16.8%) events for OS. O-Chl as compared to Chl resulted in significantly improved PFS (median 22.4 vs. 13.1 months, HR 0.54, p<0.01). In univariate analyses, TP53mut (HR 2.07, p<0.01), NOTCH1mut (HR 1.50, p=0.01) and SF3B1mut (HR 1.66, p=0.01) were associated with shorter PFS, whereas ATM and other candidate genes showed no association (ATMmut: HR 1.40, p=0.07). Analyzing both treatment arms separately, TP53mut had an impact on PFS with Chl and O-Chl treatment (HR 1.92, p=0.04 and HR 2.49, p<0.01). Notably, NOTCH1mut was associated with outcome in O-Chl only (HR 2.01, p<0.01 vs. HR 1.14, p=0.59) resulting in a reduced beneficial effect from the addition of Ofatumumab to Chlorambucil treatment. ATMmut and BIRC3mut mutations were only adverse prognostic factors with Chl monotherapy (ATMmut: HR 1.69, p=0.05 vs. HR 1.35, p=0.27; BIRC3mut: HR 2.84, p=0.04 vs. HR 0.99, p=0.99). OS was reduced significantly only in TP53mut cases (HR 3.69, p<0.01). Of note, none of the MYD88mut cases (n=10) had died within the follow-up period. To identify genomic factors of independent prognostic impact, we performed multivariable Cox regression analyses for PFS and OS including treatment arms, 11q-, +12q, 17p-, IGHV and all candidate gene mutations. For PFS, the following independent prognostic factors were identified: O-Chl (HR 0.46, p<0.01), 17p- (HR 3.14, p<0.01), 11q- (HR 1.57, p=0.01), unmutated IGHV (HR 1.43, p=0.02), TP53mut (HR 1.81, p=0.03), NOTCH1mut (HR 1.63, p<0.01) and SF3B1mut (HR 1.54, p=0.02). Regarding OS, only 17p- (HR 4.07, p<0.01), and unmutated IGHV (HR 1.81, p=0.05) were identified as independent adverse prognostic factors with TP53mut showing a trend (HR 2.14, p=0.10). CONCLUSION: We performed mutational analyses for the 8 most frequent mutated genes in CLL in the COMPLEMENT1 trial evaluating 1st line O-Chl against Chl. An independent prognostic impact was identified for TP53mut, NOTCH1mutand SF3B1mut regarding PFS. Notably, NOTCH1mut affected outcome mainly with O-Chl treatment, whereas ATMmut and BIRC3mut were associated with outcome with Chl monotherapy. In multivariate analysis for OS, none of the gene mutations, but the established parameters IGHV and 17p- had independent prognostic impact.

Abstract Introduction Patients with asymptomatic early Rai or Binet stage chronic lymphocytic leukemia (CLL) do not benefit from mono-chemotherapy. Therefore, clinical observation without treatment (watch&wait; W&W) has been the gold standard for the management of these patients. Chemoimmunotherapy with FCR improves the outcome of patients with advanced CLL, but its efficacy in early stage disease has not been investigated. Several clinical and biological variables identify those patients who have a high risk of an aggressive disease course and who might benefit from early interventions. Consequently, this trial was conducted to test the value of FCR treatment in patients with early stage, high-risk CLL. Methods This report represents the endpoint and safety analysis of a randomized German-French cooperative phase III trial comparing the efficacy of early versus deferred FCR therapy in treatment-naïve Binet stage A CLL patients with a high risk of disease progression. Risk assessment was performed using 4 prognostic markers: Lymphocyte doubling time <12 months, serum thymidine kinase >10 U/L, an unmutated immunoglobulin heavy chain variable region gene (IGHV) status, and presence of unfavorable cytogenetics (del11q, del17p, trisomy 12) by fluorescence-in-situ hybridization. Presence of at least 2 versus less than 2 of these factors defined “high-risk” versus “low-risk” CLL. High-risk CLL patients were further randomized to receive either 6 cycles FCR (HR-FCR) or to be followed by a W&W strategy (HR-W&W). Patients with low-risk CLL were observed only (LR-W&W). Results Between 2005 and 2010, a total of 824 patients was enrolled, 423 patients in 69 centers of the German CLL Study Group and 401 patients in 25 centers of the French Cooperative Group on CLL. The diagnosis of CLL needed to be established no longer than 12 months prior to enrollment and patients were required to present with previously untreated stage Binet A CLL at the time of inclusion. Overall, 800 patients (97.1%) were stratified, 201 of them categorized as high-risk CLL (25.1%). There was no significant difference between high-risk patients from the two study groups regarding common baseline characteristics (e.g., age, sex, comorbidity, immunophenotype) and the distribution of risk factors used for stratification. 100 out of 201 high-risk patients were randomized to receive FCR therapy (HR-FCR), while 101 patients were allocated to the HR-W&W arm. 18 out of 100 patients (18%) withdrew consent for FCR therapy before treatment was started. 71 (86.6%) of 82 treated patients completed ≥4 cycles. The most common of 228 CTC grade III/IV adverse events reported within 12 months after treatment initiation were hematotoxicity (73.2% of patients) and infections (19.5% of patients). Three patients (3.7%) developed fatal CTC grade V infections (2 septic bacteremias, 1 of them with pulmonary aspergillosis; 1 encephalitis). Out of 79 patients available for response assessment until month 12 after treatment start, 76 showed a complete or partial remission (ORR 96.2%), 2 patients had stable disease (2.5%) and 1 patient had progressed (1.3%). After a median follow up of 46 months (range 0-88 months), HR-FCR patients demonstrated a significantly improved event-free survival (EFS) compared to HR-W&W patients (median EFS not reached versus 24.5 months, respectively, P<0.0001, Fig. 1). Overall survival was not significantly different between HR-FCR and HR-W&W with 181 high-risk patients (90%) being alive at last follow up. Both, HR-FCR and HR-W&W patients exhibited a significant shorter event-free and overall survival than LR-W&W patients, demonstrating an efficient prognostic segregation of patients by the risk assessment used for this trial (analysis based on the German LR-W&W cohort only, complete German-French LR-W&W data will be presented at the meeting). Conclusion This is the first randomized phase III trial investigating the efficacy of FCR chemoimmunotherapy in early stage CLL. So far, the study has revealed two major results: 1. A combination of clinical and biological factors can be used to identify early stage CLL patients who experience a rapid disease progression with unfavorable outcome, 2. FCR chemoimmunotherapy substantially improves event-free survival in early stage high-risk CLL. Disclosures: Langerbeins: Roche: travel grants Other.

Abstract Background: Myelofibrosis (MF) is a clonal neoplastic disease resulting in bone marrow fibrosis, splenomegaly, and debilitating constitutional symptoms. The Janus kinase (JAK) pathway is often dysregulated in MF, and agents targeting this pathway have demonstrated efficacy in this disease. Ruxolitinib (RUX), a potent JAK1/JAK2 inhibitor, demonstrated superiority in spleen volume reduction, symptom improvement, and survival compared with the control arm in the phase III COMFORT-I and COMFORT-II studies. Panobinostat (PAN), a potent pan-deacetylase inhibitor (pan-DACi), inhibits JAK signaling through disruption of the interaction of JAK2 with the protein chaperone heat shock protein 90. In phase I/II studies, PAN has shown splenomegaly reduction and improvement of bone marrow fibrosis. The combination of RUX and PAN demonstrated synergistic anti-MF activity in preclinical studies. These preliminary results led to the initiation of a phase Ib study evaluating the combination of RUX and PAN in patients (pts) with MF. The updated results from the expansion phase of this trial are presented here. Methods: Eligible pts had intermediate-1, -2, or high-risk primary MF, post-polycythemia vera MF, or post-essential thrombocythemia MF by International Prognostic Scoring System criteria, with palpable splenomegaly (≥ 5 cm below the costal margin). The primary objective was determination of the maximum tolerated dose (MTD) and/or recommended phase II dose (RPIID). Secondary objectives included safety, efficacy, and pharmacokinetics. Exploratory endpoints included assessment of improvement in bone marrow fibrosis and reduction of JAK2 V617F allele burden. The treatment schedule was RUX (5-15 mg) twice daily (bid) every day and PAN (10-25 mg) once daily 3 times per week (tiw; days 2, 4, and 6) every other week (qow) in a 28-day cycle. Following dose escalation and identification of the potential RPIID, additional pts were enrolled into the expansion phase and treated at this dose. Results: As of March 14, 2014, a total of 61 pts were enrolled (38 escalation phase and 23 expansion phase). The median duration of exposure to PAN and to RUX was 24.6 weeks and 24.0 weeks, respectively, for pts treated in the expansion phase. Three DLTs were observed in the escalation phase (grade 4 thrombocytopenia [n = 2], grade 3 nausea [n = 1]). No MTD was reached. The RPIID was confirmed to be RUX 15 mg bid and PAN 25 mg tiw qow in May 2014. Among the 34 pts treated at the RPIID, grade 3/4 adverse events (AEs) regardless of causality included anemia (32%), thrombocytopenia (24%), diarrhea (12%), asthenia (9%), and fatigue (9%). AEs led to discontinuation in 6% of pts treated at the RPIID. Two pts treated at the RPIID died due to causes unrelated to study treatment (1 due to myocardial infarction and 1 due to progression of myelofibrosis). Among the pts treated at the RPIID, 79% showed a >50% decrease in palpable spleen length, with 100% decrease (non-palpable spleen) being observed in 53% of pts. Additionally, 48% of pts treated at the RPIID in the expansion phase achieved ≥35% reduction in spleen volume (Figure). These results are similar to those observed for spleen volume response at 24 weeks among pts who received single-agent RUX on the phase III COMFORT-I (41.9%) and COMFORT-II (32%) studies. Conclusions: The combination of the JAK1/JAK2 inhibitor RUX and the pan-DACi PAN was well tolerated and resulted in high rates of reductions in splenomegaly in pts with intermediate- and high-risk MF. Although a relatively larger proportion of patients experienced spleen volume reductions at week 24 as compared to the COMFORT studies, the smaller sample size, shorter follow up times and potential differences in the patient populations preclude definitive comparisons. Similar to COMFORT-I and II trials, hematological AEs, specifically anemia and thrombocytopenia, were the most common AEs observed in pts treated with the combination therapy. Pts continue to be treated in the expansion phase at the RPIID. Updated safety, efficacy, and exploratory analyses on bone marrow fibrosis, JAK V617F allele burden, and biomarkers, including cytokines, will be presented.

Abstract Background. Current upfront treatment of light chain (AL) amyloidosis is often based on bortezomib in patients. However, data on the safety and efficacy of bortezomib in this setting mostly derive from uncontrolled, retrospective series, that are difficult to compare due to different proportion of patients with advanced disease. Here we report the analysis of a multicenter randomized phase III trial comparing MDex, a current standard of care, and MDex with the addition of bortezomib (BMDex) in newly-diagnosed AL amyloidosis that was performed in Europe and Australia (EMN-03 study, NCT01277016). Patients and Methods. Main eligibility criteria included measurable disease (M-protein >10 g/L or dFLC >50 mg/L), estimated glomerular filtration rate (eGFR) ³30 mL/min, and adequate liver function. Previously treated patients, those who had >30% bone marrow plasma cell or lytic bone lesions, NYHA class >II heart failure, grade 3 sensory or grade 1 painful peripheral neuropathy, or ECOG performance status >2 were excluded. In January 2013 the protocol was amended to include Mayo stage III patients, provided their NT-proBNP was <8500 ng/L (stage IIIa). Patients were randomized to receive either MDex (melphalan at 0.22 mg/kg and dexamethasone at 40 mg daily for 4 consecutive days every 28 days) or BMDex (bortezomib added at 1.3 mg/m2, on days 1, 4, 8, and 11 in cycles 1 and 2, and on days 1, 8, 15, and 22 in the following cycles). The primary endpoint was overall hematologic response at 3 months. Treatment was continued until completion of MDex cycle 9 or BMDex cycle 8, or achievement of CR or of at least partial response (PR) plus organ response after cycle 6, and was discontinued in case PR was not achieved by cycle 3. Enrollment is now completed (110 patients) with the last patient enrolled in February 2016 (database lock: July 25, 2016). Results. Patients' characteristics are reported in the Table. The proportion of patients experiencing at least 1 grade 3-4 severe adverse events (SAE) was similar in the MDex and BMDex arms (49% vs. 60%, P=0.11). The total number of reported adverse events per cycle was lower in the MDex group (10% vs 23%, P<0.01). Most common SAEs (MDex vs. BMDex) were cytopenia (4% vs. 7%, P=0.04), fluid retention (3% vs. 6%, P=0.02), and neuropathy (0 vs. 2%, P<0.01). One patient died within 3 months in the MDex arm and 3 in the BMDex group (P=0.28). Response was evaluated by intent to treat. Hematologic response rates after cycle 3 were 51% and 78% (P=0.001), with 28% and 53% complete response (CR) /very good partial response (VGPR) (P=0.003), in the MDex and BMDex arms, respectively. Overall hematologic response at the end of treatment, after a median of 5 cycles, was 56% and 81% (P=0.001), with 38% and 64% CR/VGPR in the MDex and BMDex arms, respectively (P=0.002). Cardiac response was reached in 8 of 33 evaluable patients treated with MDex (24%) and 10 of 26 (38%) who received BMDex (P=0.119). Renal response was attained in 17 of 35 patients (48%) in both arms. However, there was a higher proportion of cardiac progression in the MDex arm with borderline statistical significance (32% vs. 15%, P=0.054). After a median follow-up of living patients of 25 months, 26 patients (24%) died, 16 in the MDex arm and 10 in the BMDex arm with no significant difference in survival (Figure 1a). Achievement of hematologic and cardiac response at 3 months significantly improved survival (Figures 1b and 1c). Conclusion. This is the first prospective randomized trial of novel agents in AL amyloidosis. The criteria of hematologic and cardiac response are validated in the prospective setting for the first time. The primary endpoint, hematologic response at 3 months has been reached, showing more frequent and more profound hematologic responses with BMDex, preventing progression of cardiac dysfunction, with a modest increase in toxicity. This regimen can be proposed as a new standard of care in AL amyloidosis.

Abstract Background: No approved treatment options are available to HR-MDS pts after HMA therapy. Study 04-21 (“ONTIME” trial) was a Phase III, randomized, controlled study of the efficacy and safety of rigosertib, a novel small molecule inhibitor of PI3-kinase and PLK pathways, in a heterogeneous population of MDS pts who had relapsed after, failed to respond to, or progressed during administration of HMAs. The study was conducted at 87 sites in the United States and 5 European countries. Methods:From Dec 2010 to Aug 2013, 299 HR-MDS pts [<30% bone marrow blasts (BMBL)] who had progressed on (37% of total enrollment), failed to respond to (25%), or relapsed after (38%) HMA treatment were stratified on BMBL count and randomized 2:1 to receive rigosertib (199 pts) or BSC (100 pts). Rigosertib was administered at 1800 mg/24 hr for 72-hr as a continuous intravenous (CIV) ambulatory infusion, every 2 weeks for the first 16 weeks, and then every 4 weeks. The primary endpoint was overall survival (OS), analyzed on an intention-to-treat (ITT) basis using the Kaplan-Meier method stratified on BMBL (5% to 19% vs. 20% to 30%). The trial had a 95% power to detect a 13-wk increase in median OS from 17 wks on BSC, with a 2-sided alpha = 0.05. The following results are based on 242 deaths: 161 in the rigosertib arm and 81 in the BSC arm. Results : Overall, the 2 arms were balanced in terms of baseline characteristics, with the majority of pts being male (66%), and White (82%). Age ranged from 50-90 yrs in the rigosertib arm and 55-86 years in the BSC arm (median, 74 yrs). The majority of pts (85%) had an Eastern Cooperative Oncology Group (ECOG) score of 0 or 1. The median duration of the last HMA therapy was 8.8 months (mo) in the rigosertib arm and 10.3 mo in the BSC arm; 127 (64%) of rigosertib pts and 57% of BSC pts were classified as “primary HMA failure” (ie, they failed to respond to or progressed during HMA therapy, as defined by Prebet et al, J Clin Oncol, 2011). A 2.3-mo improvement in median OS was found in the overall (ITT) population (8.2 mo rigosertib vs. 5.9 mo BSC) (Figure 1). The ITT survival for rigosertib was similar to that noted in Phase I/II studies (35 weeks). The stratified log-rank p-value was 0.33. The stratified hazard ratio was 0.87, which was quite different from the ratio of medians (5.9/8.2 = 0.72), due to the fact that the 2 survival curves converged at 15 mo. Notably, among the 184 patients with primary HMA failure, the median OS was 8.6 mo in the rigosertib arm (N = 127) vs. 5.3 mo in the BSC arm (N = 57), HR= 0.69, p= 0.040 (Figure 2). Multivariate Cox regression, adjusting for pretreatment prognostic factors, showed little change in the treatment effect. The following subgroups were correlated with better OS: pts with failure of/progression on HMA treatment, pts with duration of HMA treatment ≤ 9 mo, pts < 75 years of age, and pts with very high risk per IPSS-R (Figure 3). Rigosertib was well tolerated, with a median dose intensity of 92%. There were no significant compliance or operations issues related to ambulatory continuous infusion. Protocol-defined dose reductions were reported in 5% of pts, with 24% experiencing dose delays of >7 days, mostly due to unrelated adverse events (AEs). No obvious differences between rigosertib and BSC were found in the incidence of AEs (rigosertib, 99%; BSC, 85%) or of ≥ Grade 3 AEs (rigosertib, 79%; BSC, 68%). In the rigosertib arm, AEs reported by ≥ 20% of pts, irrespective of severity or causality, were nausea (35%), diarrhea (33%), constipation (31%), fatigue (30%), fever (27%), anemia (22%), and peripheral edema (21%). Rigosertib had low myelotoxicity, consistent with previous clinical experience. Conclusions:Although the primary endpoint in this Phase III study of rigosertib vs BSC in pts with HR-MDS did not reach statistical significance in the ITT population, encouraging rigosertib treatment-related improvement in OS was noted in several subgroups of MDS pts, including those with “primary HMA failure and in patients in the IPSS-R Very High Risk category. CIV therapy with rigosertib had a favorable safety profile in this orphan population of elderly pts with MDS. Figure 1 Figure 1. Figure 2 Figure 2. Figure 3 Figure 3.

Introduction. Myelodysplastic Syndrome (MDS) is a disease of the elderly. Apart from IPSS, IPSS-R and WPSS, several indexes incorporating patient comorbidities (such as the MDS CI index- Della Porta et al Haematologica 2011, the HCT-CI index - Sorror et al Blood 2005) and performance status (the GFM index- Itzykson et al Blood 2011) have been used to predict outcome in MDS patients treated with azacytidine (AZA). We sought to investigate the effect of comorbidities on the outcome after AZA in a large group of patients from the MDS registry of the Hellenic MDS Study Group. Methods. The present study has been conducted as a retrospective observational cohort one. It included high-risk MDS and low blast count AML patients treated with AZA from 26 centers in Greece from 2007 to 2018. T-test and ANOVA were used to compare scale variables between two or more groups respectively. Univariate analysis of nominal and scale survival data was performed using Kaplan-Meier survival curves and Cox regression respectively. All variables achieving p<0.05 at univariate analysis were considered eligible for multivariate analysis; the latter was based on Cox regression method. Results. We analyzed 536 consecutive patients. Patient characteristics are depicted in Table 1. The median follow-up period was 27.5±4.8 months. 371 patients received at least four cycles of AZA and 165 patients received less than 4 cycles of AZA. Patients who received ≥4 cycles of AZA did not differ from those who received <4 cycles regarding gender, age, estimated Glomerular Filtration Rate (eGFR), cardiovascular, renal, and tumor comorbidities. Significantly higher IPSS-R and GFM scores at baseline were found in the group of patients receiving < 4 cycles of AZA compared to patients who received ≥ 4 cycles of AZA (p=0.042 and 0.05 respectively), while transfusion dependence at baseline occurred more often in patients who received ≥ 4 cycles of AZA (p=0.039). To assess the prognostic significance of risk factors on leukemia free survival (LFS) and overall survival (OS), univariate and multivariate analysis for the whole population was performed, as well as a landmark analysis for patients who were treated with at least 4 cycles of AZA. ECOG performance status and the presence of peripheral blasts were independent prognostic factors for LFS and OS for the whole cohort analysis while response to AZA and the presence of peripheral blasts were independent prognosticators for LFS and OS in the landmark analysis. In addition, prior low dose cytarabine was an independent adverse prognostic factor for LFS in the landmark analysis. As regards comorbidities, neither of MDS-CI, HCT-CI and GFM systems independently predicted LFS or OS in either analysis, but eGFR with a cut-off of 45 ml/min was a strong and independent prognosticator for LFS and OS in both the standard and the landmark analysis. Kaplan-Meier survival curves regarding LFS and OS at AZA initiation and landmark analysis after 4th cycle of AZA in relation with eGFR are shown in Figure 1. Conclusion. This is the first study to demonstrate the importance of eGFR at baseline as a prognostic marker for LFS and OS in high-risk MDS and low-blast AML patients treated with AZA. The role of comorbidities and PS needs to be further evaluated in this patient group.

Abstract Abstract 1092 Background: Newly diagnosed myeloma (MM) patients who receive thalidomide-based regimens have a high risk of thromboembolic events. Preliminary studies on MM patients receiving a combination of lenalidomide (R) and dexamethasone have shown an increased incidence of thrombosis as well, with a calculated odds ratio of about 3.5 of developing thrombosis. Aims: In a prospective, multicenter phase III trial (RV-MM-PI-209) newly diagnosed patients were treated with lenalidomide and low-dose dexamethasone (Rd) induction and subsequently randomized to receive consolidation with lenalidomide + melphalan + prednisone (MPR) or high dose melphalan (MEL200). In this sub-study we evaluated the safety and the efficacy of low-molecular weight heparin (LMWH) or low-dose aspirin (ASA) as anticoagulant prophylaxis during Rd induction and MPR consolidation. End-points were incidence of venous thromboembolism (VTE), acute cardiovascular events, sudden death, major and minor bleeding. Methods: 402 newly diagnosed MM patients were enrolled in the randomized trial RV-MM-PI-209. Treatment schedule included four 28 day cycles of lenalidomide (25 mg days 1–21) and low-dose dexamethasone (40 mg days 1,8,15,22) (Rd) as induction. As consolidation, patients were randomized to receive six 28-day cycles of melphalan (0.18 mg/kg days 1–4), prednisone (2 mg/kg days 1–4) and lenalidomide (10 mg days 1–21) (MPR, N=202) or tandem melphalan 200 mg/m2 with stem-cell support (MEL200, N=200). All eligible patients were randomly assigned to receive LMWH (Enoxaparin 40 mg/d, N=166) or ASA (Aspirin 100 mg/d, N=176) for the duration of the induction therapy and for consolidation therapy in the MPR group; 60 patients were excluded from this sub-study because of indication for anticoagulant/antiplatelet therapy or high-risk of bleeding. Results: Patient characteristics and distribution of major risk factors were similar in the two groups. At the time of the present analysis 381 and 130 patients are evaluable during Rd induction and consolidation respectively. During the induction phase, the overall incidence of any grade 3–4 thrombotic events was 1% in the LMWH group, 2,4% in the ASA group (p=.45). VTE, mostly of the lower limbs were equally distributed in the two groups (1%; p not significant), while pulmonary embolism was observed only in the ASA group (2%; p not significant). Median time to onset of thrombotic events for patients who received LMWH or ASA were 2.1 and 1 months, respectively. No acute cardiovascular events were observed and only minor bleeding was detected in the LMWH group (1%). During consolidation no thrombotic events were observed in the MPR group, only one central venous catheter thrombosis was observed in the MEL200 group. Conclusion: The overall incidence of thrombotic events was less than 5% in all groups and confirmed the safety of low dose dexamethasone in association with Lenalidomide. No significant benefit was seen with LMWH over ASA in this patient population. LMWH and ASA are likely to be effective thromboprophylactic regimens in lenalidomide treated patients with newly diagnosed multiple myeloma. The analysis will be updated for the meeting.

Abstract Background. The prognostic significance of bone marrow (BM) fibrosis grade in pts with primary myelofibrosis (PMF) is debated. A fibrosis grade greater than 1 was associated with a 2-fold higher risk of death compared with pts with early/prefibrotic MF (grade 0) [Thiele J, Ann Hematol 2006]. Recent data suggest that more accurate prediction of survival is achieved when fibrosis grade is added to IPSS [Verner C, Blood 2008; Giannelli U, Mod Pathol 2012]. Aim. To analyze the prognostic impact of fibrosis in diagnostic BM samples of 540 WHO-2008 diagnosed PMF pts with extensive clinical and molecular information collected in 6 Italian centers belonging to AGIMM (AIRC-Gruppo Italiano Malattie Mieloproliferative). Methods. The clinical variables assessed were those previously identified as prognostically relevant in the IPSS score. Published methods were used to screen mutations of JAK2, MPL, CALR, EZH2, ASXL1, IDH1/2 and SRSF2. European consensus scoring system was used to grade fibrosis (on a scale of MF-0 to MF-3). The prognostic value of fibrosis with regard to overall survival (OS) was estimated by Kaplan-Meier method and Cox regression. Results. Pts' median age was 61y; median follow-up 3.7y; median OS 10.5y; 184 pts (34.1%) died. IPSS risk category: low 33.7%, Int-1 27.7%, Int-2 19.1%, High-risk 19.5%. Mutational rate: JAK2 V617F 62.6%, CALR 20.7% (type-1/1-like 77.7%, type2/2-like-2 21.4%), MPL W515 5.9%; 62 (11.5%) were triple negative (TN). 171 pts (31.7%) were High-Molecular Risk (HMR) category (Vannucchi AM, Leukemia 2013); mutation rate: EZH2 7.2%, ASXL1 22.2%, IDH1-2 2.4%, SRSF2 8.3%. According to fibrosis grading, 50 pts were MF-0 (9.3%), 180 MF-1 (33.3%), 196 MF-2 (36.3%), 114 MF-3 (21.1%). Compared with both MF-0 and MF-1, MF-2 and MF-3 pts presented more frequently constitutional symptoms (P<.0001), larger splenomegaly (P<.0001), greater risk of developing anemia (P<.0001) or thrombocytopenia (P=.003). We found a significant association (P<.0001) between IPSS higher/Int-2 risk categories and MF-2 and -3 (20.5% and 37.8%, respectively, vs 14.8% and 6.0% for MF-0 and -1). There was no correlation between fibrosis grade and phenotypic driver mutations; in particular, TN pts were equally distributed among MF fibrosis grades (10%, 10.6%, 14.3% and 8.8% from MF-0 to -3, respectively). Conversely, the frequency of HMR pts increased progressively according to fibrosis grade: 8 pts MF-0 (16%), 46 MF-1 (25.6%), 66 MF-2 (33.7%) and 51 MF-3 (44.7%) (P<.0001). In particular, we found a significant association between fibrosis grade and ASXL1 (12%, 15%, 23.5% and 36% from MF-0 to -3; P<.0001) and EZH2 (2%, 3.9%, 8.2%, 13.2%; P=.01) mutations. Also, pts with 2 or more HMR mutated genes were preferentially MF-2 or -3 ( 0%, 4.4% 10.2% and 10.5% from MF-0 to -3; P=.001). Median OS was significantly shorter in pts with MF-2 (OS 6.7y, HR 7.3, IC95% 2.7-20.0; P<.0001) and MF-3 (OS 7.2y, HR 8.7, IC95% 3.1-24.2; P<.0001) compared with MF-1 (14.7y; HR 3.9, IC95% 1.4-10.9, P=.008) and MF-0 (P<.0001) used as reference group (OS not reached) (Figure). Excluding MF-0, MF-2 and -3 maintained negative prognostic impact with HR 1.9 (1.3-2.6; P=.001) and 2.2 (1.5-3.3; P<.0001) respectively vs MF-1. The impact of fibrosis on OS was maintained when analysis was restricted to younger (≤65y) pts. In multivariate analysis using the individual IPSS variables, grade MF-2 and -3 were independently predictive of survival (HR 3.9 (1.4-10.8), and HR 4.2 (1.5-12.0), respectively, P=.008 for both). The negative impact on survival of MF-2/-3 was maintained regardless of IPSS category, HMR status, number of HMR mutated genes and driver mutations, included as covariates (Table). In low, Int-1 and Int-2, but not high-risk IPSS categories, MF-2/-3 associated with reduced survival (P<.03). Conclusions. Overall, these results indicate that higher grades (MF-2 and MF-3) of fibrosis correlate with defined clinical and molecular variables and independently negatively impact on OS in PMF, suggesting the opportunity to explore its value in the setting of clinical and molecular prognostic scores for PMF.

Abstract Background The role of upfront autologous stem cell transplantation (ASCT) for younger patients with newly diagnosed (ND) multiple myeloma (MM) has been questioned in the novel agent era. Methods A prospective, multicenter, phase III study was designed to compare (first randomization, R1) (1:1 ratio; stratification according to ISS stage) four 42-day cycles of bortezomib-melphalan-prednisone (VMP) given at the same dosing schedule reported in the VISTA study (NEJM 2008; 359:906-17) vs either a single course or two sequential courses of melphalan at 200 mg/m2 (HDM) followed by single or double ASCT, respectively, as intensification therapy after three to four 21-day cycles of induction therapy with bortezomib-cyclophosphamide-dexamethasone and subsequent collection of peripheral blood stem cells. A second randomization (R2) to consolidation therapy with bortezomib-lenalidomide-dexamethasone vs no consolidation was performed after intensification, to be followed by lenalidomide maintenance until progression or toxicity in both arms. A primary study end point was progression-free survival (PFS) from R1. Results From February 2011 to April 2014, 1510 patients aged ≤65 years with symptomatic NDMM were registered. Of these, 1192 were eligible for R1 and were randomly assigned to receive either VMP (n=497 patients) or HDM (1±2 courses) (n=695 patients). Median age was 58 years in both groups, ISS stage III was 21% in VMP and 20% in HDM, while revised ISS stage III was 9% in both groups. Data on cytogenetic abnormalities, as detected by FISH analysis of CD138+ plasma cells, were available in 71% of patients (n=354) randomized to VMP and in 76% of those (n=529) assigned to HDM. The frequency of conventionally defined high-risk cytogenetic changes, including t(4;14) and/or del(17p) and/or t(14;16), was 25% in both arms. Median follow-up from R1 was 26 (IQR: 19-37) months. On an intention-to-treat basis, median PFS was 44 months in the VMP arm and was not yet reached in the HDM arm; 3-year estimates of PFS were 57.5% and 66%, respectively (HR=0.73; 95% CI=0.59-0.90; P=0.003). PFS benefit with HDM was retained across predefined subgroups, including patients with ISS stage I (HR=0.69; CI=0.48-0.98; P=0.037), revised ISS stage II (HR=0.70; CI=0.54-0.91; P=0.008), revised ISS stage III (HR=0.54; CI=0.30-0.97; P=0.040), standard-risk cytogenetics (HR=0.75, CI=0.56-1.01; P=0.055) and a high-risk cytogenetic profile (HR=0.54; CI=0.37-0.80; P=0.002). The probability of achieving a very good partial response or higher quality response was 85.5% in the HDM group vs 74% in the VMP group (odds ratio=1.90; CI=1.42-2.54; P<0.001). In a multivariate Cox regression analysis stratified by ISS, randomization to HDM (HR=0.67; CI=0.53-0.85; P=0.001) and absence of high-risk cytogenetic abnormalities (0.71; CI=0.53-0.95; P=0.021) were the leading independent predictors of prolonged PFS. Overall survival was not yet mature and no difference between the two treatment groups was evident. Detection of minimal residual disease (MRD) after intensification therapy was performed by multiparameter flow cytometry and PET/CT in a subgroup of patients, and details are provided in a separate abstract (E. Zamagni et al). Overall, MRD negativity favorably affected PFS and OS. Conclusions In comparison with VMP as standard-dose intensification therapy, upfront HDM and ASCT significantly improved PFS and increased the rate of high quality responses. An updated analysis with a longer follow-up will be reported at the meeting. Results of this phase III study, the largest so far reported, support the conclusion that upfront ASCT still continues to be the reference treatment for fit patients with NDMM, even in the novel agent era.

Abstract Background: A substantial proportion of patients fail first line treatment of diffuse large B-cell lymphoma. Currently available salvage therapies are often ineffective and cannot be tolerated, especially for elderly patients. Thus, probably less than 25% of patients achieve a long lasting remission. Regimens like gemcitabine/oxaliplatin, or bendamustin, both in combination with rituximab are available for elderly or after failure of HDT, however induce only short lived responses. Obinutuzumab (GA101) is a type II anti-CD20 antibody, with preclinical evidence of superiority over rituximab in xenograft models of MCL and DLBCL. Recently a large phase III trial failed to show a benefit in patients with untreated DLBCL, although a subset analysis showed a potential benefit in a subset GCB DLBCL of patients, its value in relapsed disease is not yet finally determined. Although desirable, cumulative dose-related, progressive cardiotoxicity eliminates anthracyclines from relapse treatments. With pixantrone, a drug related to anthracyclines, a re-exposition against this drug class has been shown to be feasible, a best EOT-ORR of 37% (20% CR/CRu) was observed in a phase III trial. We thus initiated a trial combining both agents for the first time. The trial has opened in Q3/2015 and recruitment of 70 patients is completed as of 7/2018. Primary endpoint is the ORR, secondary endpoints being safety, PFS and OS. We report about available data after enrollment of the last patient. Methods: this is a multicenter, national, prospective trial. Main inclusion criteria: histologically proven DLBCL, FL grade IIIb or transformed iNHL (20% Quorum), no curative option available, relapsed and measurable disease, ECOG < 3, sufficient BM reserve, no severe concomitant diseases and given informed consent. There was no upper limit of prior treatment lines. Treatment consisted of up to 6 cycles of pixantrone 50mg/m² day 1, 8 and 15 of each cycle, obinutuzumab 1000 mg flat dose day 1, 8 and 15 of cycle one and day 1 of each subsequent cycle. Interim staging was scheduled after 3 cycles. Results: Basic data are available of 67 patients, all were caucasian, 37 were female the other 30 male and median age was 75 years. Most of the patients suffered from DLBCL (49 pts, 68%), 68% had advanced stage at diagnosis and the median secondary IPI was 3. Data collection is ongoing, until now data of 32 patients are fully available and updated results will be presented. Median number of prior therapies was 2 (1 to 6). Treatment seemed to be well tolerated, median number of cycles applied was 3, pre-mature stop of treatment was primarily based on progression. Response evaluation: at this time 13/32 (40.6%) evaluable patients responded with 5 patients achieving CR/CRu (15.6%) and 8 a PR. One year after initiation of treatment 54% of patients remained alive. Median follow up is 8.2 months. Median PFS and OS is 82 day and not reached, 1 year PFS and OS are 37% and 54%, respectively, no patient experienced relapse if the patient remained free from relapse at one year. Observed toxicity was predominantly hematologic. The following hematologic grade 3/4 adverse events were observed: leukopenia (9.4%) neutropenia (75%), thrombocytopenia (12.5%). The febrile neutropenia rate was 6.3%. Non-hematologic grade 3/4 adverse events were very rare, no single side effect was observed with a frequency of 5% or more. Summary: the combination of Obinutuzumab and Pixantrone is feasible and safe. Early response rates are interesting. Importantly, although some patients experience progress early, a promising proportion shows long lasting remissions. Molecular analyses are ongoing, as well as a detailed analysis on the impact of factors such as of number of prior treatments, status at inclusion. Figure. Figure.
