The Impact

Abstract Introduction Mantle cell lymphoma (MCL) frequently impacts elderly patients (median age of diagnosis is 68), and management of these patients can be difficult due to the presence of comorbidities in this group. Presence of comorbidities is associated with inferior outcomes in many hematologic malignancies but there has not been a systematic assessment of comorbidities in MCL. We utilized the Charlson Comorbidity Index (CCI) to describe the presence of comorbidities in MCL patients and to explore their impact on patient outcomes. Methods We included patients with MCL evaluated at Emory between January 1, 2000 and December 31, 2016. Patients with limited or inadequate follow-up or for whom data to determine the CCI were inadequate were excluded. We determined the CCI at the time of initiation of treatment for all patients with MCL and excluded "lymphoma" from this calculation. Patients were categorized into severity classes based on their summed scores. The median score of 1 was used to delineate the "low" and "high" CCI groups. For each group (low and high CCI), we evaluated baseline demographic, clinical and treatment characteristics and identified specific toxicity-related outcomes including: failure to complete induction chemotherapy, unplanned hospitalizations, or treatment related toxicities. Progression-free (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method, and we assessed for the impact of CCI score on PFS and OS using Cox proportional hazards models. Results Of 178 patients with MCL, 129 were male (73.3%) and median age was 61 (32-86). One hundred forty patients (86.4%) had stage IV disease. Among the 99 reported values, 31 patients (31.3%) had an elevated LDH, and ECOG PS was 0 in 47 patients, 1 in 66 patients, and 2-4 in 8 patients. Induction therapy was R-HyperCVAD (n=79; 45.4%), R-CHOP (n=49; 28.2%), BR (n=13; 7.5%) RCHOP/RDHAP (n=3; 1.7%) and Other (N=29; 16.7%). The CCI scores for the whole cohort were 0 in 78 pts (43.8%), 1 in 57 pts (32%), 2 in 24 pts (13.5%) and 3+ in 19 pts (10.7%; See Figure 1). One hundred thirty-five patients (75.8%) patients had a low CCI score (0-1) and 43 patients (24.2%) had a high CCI score (>1). Compared to patients with a low CCI, those with high CCI were older (median 67 years vs 59 years, p<0.001), were more likely to have B-symptoms at diagnosis (48% vs 30%, p=0.04) and had a decreased baseline platelet count (median 137 vs 178, p=0.02). Among the 83 patients who completed an intensive induction regimen, that contained high dose cytarabine, 71 (85.5%) had a low CCI and 12 (14.5%) had a high CCI. Twenty-eight patients experienced an unplanned hospitalization during induction, including 23 in the low CCI group (22%) and 5 in the high CCI group (16%; p=0.49). Seventeen patients de-escalated or discontinued induction therapy prematurely including 13 (12.4%) in the low CCI group and 4 (13.3%) in the high CCI group (p=1.00). There was no significant difference in OS between the low- and high-CCI groups (5-year OS 70.3% vs 68.7%, p=0.9; See Figure 2). Within the cohort of patients treated with intensive induction therapy, there was no significant impact of CCI on incidence of unplanned hospitalizations, de-escalation or discontinuation of therapy, or OS (p> 0.3). Conclusion CCI score was not shown to be a reliable predictor of unplanned hospitalizations, premature cessation of chemotherapy, or OS in our cohort, although many of our patients had very limited comorbidities. These results suggest that patients with limited comorbid conditions can likely be successfully managed with appropriate supportive care and should be considered for the most effective regimens. Future studies with a larger patient population with increased number of comorbidities may improve our ability to detect the impact of CCI on these outcomes and explore the relative contribution of specific comorbidities in MCL.

Abstract Abstract 403 Background: Mantle Cell Lymphoma (MCL) is an uncommon histology of non-Hodgkin's lymphoma (NHL) with an unfavorable prognosis for which optimal initial therapy has not been clearly defined. Despite a number of single center studies and uncontrolled trials examining first-line therapy options in MCL, no randomized clinical trials or observational studies have directly compared initial therapeutic options in a single cohort of patients. The role of aggressive induction therapy versus sequential standard chemotherapy remains uncertain, particularly in younger patients. We therefore used the NCCN NHL Outcomes Database to compare R-HyperCVAD, R-CHOP followed by HDT/ASCR and R-CHOP alone as first-line therapy. Our endpoints were progression-free survival (PFS) and overall survival (OS). Methods: The NCCN Non-Hodgkin's Lymphoma Outcomes Database is a prospective cohort study collecting comprehensive clinical, treatment, and outcome data for patients seen at 7 participating NCCN centers. Overall, 229 patients <65 years old with newly diagnosed MCL presented at NCCN institutions between August 2000 and February 2009. Patients were excluded if they (1) were enrolled in clinical trial (n=27), (2) did not receive Rituximab therapy (n=27), (3) did not receive either R-HyperCVAD or R-CHOP induction therapy (n=10), or (4) received both R-CHOP and R-HyperCVAD as induction (n=9). Induction therapy was determined as the initial chemo-immunotherapy received within 180 days of diagnosis. HDT/ASCR consolidation was defined as a transplant after achieving remission. In the R-CHOP+ HDT/ASCR group, ASCR was initiated within 100 days of induction therapy for 90% of patients. The maximum time from induction to ASCR was 172 days. In total, 156 patients were included in the final analysis. Median follow-up was 30 months. Results: Overall, 28 (18%) patients received R-CHOP alone, 29 (19%) received R-CHOP+HDT/ASCR, and 99 (63%) received R-HyperCVAD. No significant differences were observed between therapy groups with regards to co-morbidity (p=0.419), ECOG performance status (p=0.216), B symptoms (p=0.685), bulky disease (p=0.647), IPI risk group (p=0.247), or bone marrow involvement (p=0.651). No difference in PFS (p=0.546) was observed between the R-HyperCVAD and R-CHOP+HDT/ASCR arm (figure 1a). R-CHOP without consolidation had significantly poorer PFS than both R-HyperCVAD (p=0.001) and R-CHOP+HDT/ASCR (p=0.001). No significant differences in OS were observed between the three groups. However, there was a strong trend favoring R-HyperCVAD over R-CHOP (p=0.082, figure 1b). Conclusion: R-CHOP was inferior to both R-HyperCVAD and R-CHOP+HDT/ASCR, which had equal PFS and OS in patients with de novo mantle cell lymphoma. Even with these aggressive induction regimens in younger patient populations, the median PFS in these cohorts was only 3 years. Future trials should focus on incorporating novel agents rather than comparing efficacy of current suboptimal regimens.

To assess the efficacy of radioimmunotherapy (RIT) with 90yttrium-ibrutinib-tiuxetan (90Y-IT) in mantle cell lymphoma, data from 90 patients registered in the RIT Network with a median follow-up (FU) of 5.5 years after RIT were evaluated. 90Y-IT was given as first-line therapy in 45 (50%) (consolidation 44 pts., primary therapy 1 pt.) and at relapse in 45 (50%) patients (consolidation 24 pts., recurrence 12 pts., therapy refractory 3 pts., conditioning 2 pts., other 4 pts.). As a first-line treatment, 30 patients (pts.) (67%) achieved CR, 10 pts. (22%) PR%., 1 pt. (2%) PD, and for 4 pts. (9%) no response data was available. At relapse, CR was achieved in 17 pts. (38%), PR in 6 pts. (13%), SD in 2 pts. (4%), and 6 pts. (13%) had PD, while the response was not documented for 14 pts. (31%). After a median FU of 5.5 years, median PFS for all patients was 2.11 (95%CI: 1.03-2.32) years, and median OS was 4.05 (95%CI 2.79-7.21) years. Eleven pts. (12.2%) developed second malignancy. In conclusion, this is the largest report of MCL pts. treated with 90Y-IT to date. 90Y-IT was most often used as consolidation after first- and second-line chemotherapy and may improve the results achieved using chemoimmunotherapy alone. However, the results are less encouraging compared to treatment with small molecules such as ibrutinib.

Abstract Abstract 110 Background: Mantle Cell Lymphoma (MCL) has been characterized by poor long term prognosis with a median survival of only 3 to 4 years. However, outcome has improved during the last decades. In its first randomized trial, the MCL net demonstrated that myeloablative consolidation followed by ASCT resulted in a significant prolongation of PFS in advanced stage MCL (Dreyling et al Blood 2005). Recent phase II studies suggested that the addition of rituximab to CHOP like chemotherapy and/or high dose ARA-C may significantly improve remission rates and PFS. A French phase II trial using sequential R-CHOP/R-DHAP followed by ASCT showed an overall response rate of 95% with a CR rate of 61% translating into a median EFS of 83 months and a 75% survival rate at 5 years (Delarue et al ASH 2008). Methods: To evaluate the potential superiority of a high dose ARA-C containing regimen, the MCL net initiated a randomized trial comparing 6 courses of CHOP plus Rituximab followed by myeloablative radiochemotherapy (12 Gray TBI, 2×60mg/kg Cyclophosphamide) and ASCT (control arm A) versus alternating courses of 3x CHOP and 3x DHAP plus Rituximab followed by a high dose ARA-C containing myeloablative regimen (10 Gray TBI, 4×1,5 g/m2 Ara-C, 140mg/m2 melphalan) and ASCT (experimental arm B). Patient eligibility criteria included previously untreated MCL stage II-IV up to the age of 65 years. Histological diagnosis was confirmed by a central pathology review board. The primary end point time to treatment failure (TTF) was monitored continuously by a sequential procedure based on a one sided triangular test. Stable disease after induction, progression or death from any causes, were considered as treatment failure. Sample size was calculated to detect a hazard ratio of 52% for arm B with a power of 95%. Randomization was stopped as soon as a significant difference was observed between the two arms. Results: From July 2004 to May 2010, 497 patients were randomized in 4 countries (Germany, France, Poland, Belgium). The 391 patients evaluable for the primary analysis (19 no MCL, 87 not yet documented) displayed similar characteristics in both treatment arms: median age 55 vs 56 years, male 78% vs 79%, stage IV 85% vs 79%, B symptoms 43% vs 33%, ECOG >2 5% vs 5%, elevated LDH 37% vs 38%, and MIPI low/int/high risk 61%/25%/14% vs 62%/23%/15%, respectively. After induction overall response was similarly high in both arms (A: 90% vs B: 94%; p=0.19) and CR rate and combined CR/CRu rate were significantly higher in arm B (26% vs 39%; p=0.012 and 41% vs 60%; p=0.0003). The number of patients transplanted was similar in both arms (72% vs 73%) and after transplantation overall response and CR rates were comparable in both arms (97% vs 97% and 63% vs 65%, respectively). After a median follow up of 27 months, patients in arm B experienced a significantly longer TTF (49 months vs NR; p=0.0384, hazard ratio 0.68) mainly due to a lower number of relapses after CR/CRu/PR (20% vs 10%), whereas the rate of ASCT-related deaths in remission was similar in both arms (3% vs 4%). Although CR rate after ASCT was comparable in both arms, remission duration (RD) after ASCT was superior in Arm B (48m vs NR; p=0.047). Interestingly, for patients in CR after ASCT, RD after ASCT was also presumably superior in arm B (51 months vs NR; p=0.077). At the time of analysis overall survival was similar in both arms with medians not reached and 79% vs. 80% survival rates at 3 years (p=0.74). Safety after induction was comparable in both arms except for an increased grade 3/4 hematological toxicity (Hb 8% vs 28%, WBC 48% vs 75%, platelets 9% vs 74%, respectively), an excess of renal toxicity (creatinine grade 1/2: 8% vs 38%, grade 3/4: none vs 2%), and more frequent grade 1/2 nausea and vomiting in arm B. Toxicities of both conditioning regimen were similar, except for higher grade 3/4 mucositis (43% vs. 61%) in Arm B, and higher grade 1/2 liver toxicity and constipation in Arm A. Conclusions: High dose ARA-C in addition to R-CHOP+ASCT increases significantly complete response rates and TTF without clinically relevant increase of toxicity. Therefore, induction regimen containing high dose ARA-C followed by ASCT should become the new standard of care of MCL patients up to 65 years.

Abstract Abstract 474 BACKGROUND: Autologous stem cell transplantation (autoSCT) is considered as standard treatment for non-frail patients with mantle cell lymphoma (MCL). However, little is known about outcome of MCL recurrence after autoSCT. We therefore conducted a retrospective analysis of patients with MCL who failed autoSCT using the EBMT database. PRIMARY OBJECTIVE was to analyse outcome and prognostic factors after relapse following autoSCT for MCL in the rituximab era. PRIMARY ENDPOINT was overall survival (OS) from relapse. ELIGIBLE were patients aged 18 years or more who relapsed following an autoSCT for MCL performed between 2000 and 2010 and who were registered with the EBMT. Centres were contacted to provide additional information on relapse treatment. STATISTICAL ANALYSIS was based on log-rank comparisons and multivariable testing using Cox regression models. RESULTS: 1054 patients meeting the eligibility criteria could be identified in the EBMT registry. Of these, a full data set could be retrieved for 382 patients. Sixteen patients had to be excluded due to loss of follow up (n=7), wrong diagnosis (n=6), or falsely reported relapse (n=3). Median age at autoSCT of 366 evaluable patients was 59 years (range: 37 to 76), 290 patients (79%) were men. 64% had undergone autoSCT as part of 1st-line therapy; 68% and 49% had documented exposure to rituximab (RTX) and high-dose ara-C (HA) before autoSCT; and 12% had had refractory disease at autoSCT. Median time from autoSCT to relapse was 20 months (range: 0.4 to 117). 21 relapses (6%) occurred beyond 5 years after autoSCT. With a median observation time of 37 months (95% CI 32–43), median OS after relapse of the whole study group was 20 months. By univariate analysis, a long (>12mo) interval between autoSCT and relapse (p<0.001; HR 0.26; Figure 1A), 1st-line autoSCT (p=0.006; HR 0.7) refractory disease at autoSCT (p<0.001, HR 2.0) and more recent year of relapse (p<0.001, HR per year 0.9) significantly influenced OS from relapse, whereas age, gender, RTX and HA exposure did not. By multivariate analysis refractory disease at autoSCT (p<0.001, HR=2.14), remission duration after autoSCT (p<0.001 HR per 3 months 0.88) and calendar year of relapse (p<0.03, HR per year 0.93) were confirmed to be predictors for OS. In addition, HA exposure prior autoSCT adversely affected OS from relapse (p=0.06, HR 1.38). Salvage chemotherapy after relapse resulted in only 31% complete responses and 29% partial responses, whereas 40% of patients have been refractory to first salvage chemotherapy. 83 patients (23%) received an allogeneic SCT (alloSCT), whereas only 7 patients (2%) received a second autoSCT after relapse. Median time after relapse to second SCT was 7 months (range: 1 to 40). Survival after relapse for patients who received a second autoSCT was poor with no long-term survivor. AlloSCT performed for late relapse (>12mo) after autoSCT was associated with superior OS compared to patients who received an allograft upon a shorter remission duration after autoSCT (5-year OS from alloSCT 50% vs 0%; p=0.001; Figure 1B). Achievement of CR before alloSCT (p=0.05 HR=0.5), but not donor source, T-cell depletion or conditioning intensity affected OS after alloSCT. CONCLUSIONS: Patients with MCL who relapse within one year after autoSCT have an extremely dismal outcome even with alloSCT. In contrast, about half of the patients who have MCL recurrence beyond one year after autoSCT and can undergo salvage alloSCT enjoy long-term survival. It remains to be shown if a similarly good outcome can be achieved without alloSCT in this favourable selection of patients. A 2nd autoSCT does not appear to be a promising option in patients with MCL failing a 1st autoSCT.

Abstract Introduction: Mantle cell lymphoma (MCL) is an aggressive non-Hodgkin’s lymphoma with poor outcome, especially after failure of first-line treatment. Lenalidomide, an immunomodulatory drug with antineoplastic and antiproliferative effects, has shown activity in single-arm phase II studies of patients with relapsed/refractory (R/R) MCL. The present controlled randomized study compared the efficacy and safety of lenalidomide vs investigator’s choice (IC) in patients with R/R MCL. Methods: MCL-002 (SPRINT), a European multicenter, open-label, phase II study enrolled patients with up to 3 relapses or who failed prior therapy and were ineligible for intensified treatment or stem cell transplantation (NCT00875667). Oral lenalidomide was given at 25 mg/day on days 1-21 of each 28-day cycle until progressive disease (PD) or intolerability. The IC treatment consisted of single-agent therapy with cytarabine, rituximab, gemcitabine, fludarabine, or chlorambucil. Patients who progressed on IC per investigator judgment were allowed to crossover to lenalidomide. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall response rate (ORR), time to first response, duration of response (DOR), overall survival (OS), and safety. Response assessments were centrally reviewed using the modified IWG criteria. Results: 254 patients with R/R MCL were randomized 2:1 to lenalidomide (n=170) or IC (n=84). Patients had median age 68.5 years, were predominantly male (73%), and had received a median of 2 prior therapies. 91% had stage III/IV disease at diagnosis, with 34% high-risk MIPI, 43% high tumor burden, and 20% bulky disease at baseline. Overall, patients on the lenalidomide arm had a worse prognostic profile than the IC arm due to higher tumor burden and disease risk (&gt;5 percentage points for a number of parameters). After a median time of 2.9 months, 39 patients (46%) from the IC arm crossed over to lenalidomide due to PD. Overall, 84 patients remain on lenalidomide (15 having crossed over from IC) and 11 patients on IC without PD. At a median follow-up time on study of 15.9 months, the risk reduction for PFS was 39% (HR=0.61 [95% CI, 0.44-0.84]; P=0.004; Table) in favor of lenalidomide (median PFS: 8.7 months lenalidomide vs 5.2 months IC). ORR was significantly improved for lenalidomide vs IC (40% vs 11%; CR/CRu 5% vs 0%). Median time to first response was 4.3 months for lenalidomide (not reached for IC). Median DOR (16.1 vs 10.4 months) and OS on mature data (27.9 vs 21.2 months) were longer for lenalidomide vs IC. Efficacy results were consistent among subgroups. Safety data in 250 patients receiving ≥1 dose showed more dose reductions in lenalidomide-treated patients (41%) vs IC (17%), due in part to a longer median duration of lenalidomide treatment vs IC, and to strict dose modification rules for lenalidomide. The most common grade 3/4 adverse events (AEs) were neutropenia (lenalidomide 44% vs IC 34% [without increased risk of infection]), thrombocytopenia (18% vs 28%), and leukopenia (8% vs 11%). Tumor flare reaction occurred in lenalidomide patients only (10%; 2% grade ≥3); 1 patient in each arm experienced tumor lysis syndrome. Invasive second primary malignancies were identified in 4% and 5% of lenalidomide and IC treated patients, respectively. Conclusions: The MCL-002 study demonstrated a statistically significant and clinically meaningful improvement in PFS for lenalidomide over best IC monotherapy in patients with advanced R/R MCL despite a worse prognostic profile in the lenalidomide arm at baseline. In addition, ORR and CR rates, TTR, DOR, and OS were improved for lenalidomide over IC. The DOR has been remarkably consistent in various studies with lenalidomide in MCL patients. The safety profile for lenalidomide was as expected and no new safety signals were identified. The results of this first randomized, controlled study of lenalidomide showed superior efficacy compared to IC in patients with R/R MCL with a manageable toxicity profile.

Abstract Introduction Mantle cell lymphoma (MCL) is a rare and aggressive form of Non-Hodgkin's lymphoma (NHL) with poor survival outcomes. High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is recommended as first-line therapy in younger patients. However the comparative efficacy of such regimens, and of alternative therapy options (for patients unable to tolerate chemotherapy + ASCT), remain unclear. A comprehensive understanding of the current evidence is therefore required. Methods Two systematic reviews (SRs) were developed to identify efficacy and safety data for therapies used in the first-line treatment of MCL. One review identified randomised controlled trials (RCTs) and the other non-randomised studies (NRSs). Searches were carried out in EMBASE, MEDLINE, and the Cochrane Central Register of Controlled Clinical Trials electronic databases. Additionally, conference materials were screened from ASH, EHA, ESMO and ASCO proceedings from the last 2 years. All review methodologies were performed according to Cochrane best practice guidelines Results The RCT SR was run in August 2017 and updated in April 2018. Overall, 2,787 abstracts were screened. The SR included 9 full-text articles and data from 2 conference proceedings, together reporting a total of 7 independent studies. Across the RCTs, the most commonly investigated treatment regimens were rituximab + cyclophosphamide + doxorubicin + vincristine + prednisone (R-CHOP), and bendamustine + rituximab (BR). Frequently reported primary endpoints were response rates and progression-free survival (PFS). Table 1 presents the PFS and overall survival (OS) data reported in the included RCTs. Data from the RCT reporting on intensive induction chemotherapy followed by ASCT are separated from regimens that did not include ASCT. There were notable differences in median PFS rates, between both patients receiving ASCT versus patients not receiving ASCT and also between the two ASCT treatment arms. In pharmacotherapy studies, PFS ranged from 14.4 to 35.4 months, whereas the two arms of the ASCT RCT reported 51.6 and 109.2 months, respectively. Similar trends were observed in OS: the only result for patients undergoing ASCT (117.6 months) was higher than any result reported in patients not receiving transplant (range 40 - 60 months). However, study heterogeneity may affect the appropriateness of directly comparing these results. Frequently reported grade 3-4 adverse events included anemia, infusion-related reactions, nausea, neutropenia and thrombocytopenia (four of seven RCTs reported each event). The NRS SR was run in April 2018. A total of 3,290 abstracts were screened and 75 full papers were assessed. The SR included 25 full-text articles and 6 conference proceedings, together reporting a total of 18 independent single-arm studies. Several of the NRSs investigated treatment regimens that have not been described in RCT studies, including: R-CHOP with alternating or sequential rituximab + cytarabine (maxiCHOP), and cyclophosphamide + vincristine + doxorubicin + dexamethasone alternating with high dose methotrexate or cytarabine + rituximab (hyperCVAD + R). Across the NRSs, the longest median PFS was 8.5 years (102 months), in patients treated with maxiCHOP (who were young/ASCT-eligible patients). This outcome was reported in a patient population who had responded to induction therapy and were treated with consolidative ASCT. Across all studies there was heterogeneity in the eligible patient population, with some studies focusing on unfit patients and others focusing on high-dose-therapy-eligible patient populations. Many studies also reported maintenance or consolidation treatments, which would influence the long-term outcomes of the patients. Conclusions These SRs highlight the paucity of directly comparable evidence on the efficacy and safety of therapies for patients with MCL. Although there are some marked differences in patient outcomes according to therapy regimen, considerable heterogeneity in study design and patient populations make direct comparison difficult. Despite this, these SRs highlight that MCL remains a difficult subtype of NHL to treat, with short survival highlighting the high unmet need. With new and emerging therapies, additional research is essential to understand optimal regimens for first-line MCL. Table 1. Table 1. Disclosures Monga: Janssen Pharmaceutica NV: Employment.

Background and Aims. Prediction of treatment efficacy is an active and growing field of pharmacology. In the Fondazione Italiana Linfomi (FIL) MCL0208 phase III trial (NCT02354313), a 24 months lenalidomide maintenance (LM, 15 mg days 1-21 every 28 days) after high-dose immuno-chemotherapy followed by autologous transplantation (ASCT) in 300 frontline mantle cell lymphoma (MCL) patients showed substantial clinical activity in terms of Progression-Free Survival (PFS) vs observation (OBS). However, this benefit seemed not uniform across patient series. To deeper investigate the differential pattern of response to lenalidomide, a wide analysis of the host pharmacogenomics (PG) background was planned, in order to dissect whether specific germline polymorphisms of transmembrane transporters, metabolic enzymes or cell surface receptors (ABCB1, ABCG2, VEGFA, FCGR2A, NCF4, GSTP1, CRBN) might predict the drug efficacy. Actually, several single nucleotide polymorphisms (SNPs) of ABCB1 exert an effect on substrate affinity of lenalidomide for the transmembrane transporter. Moreover, VEGFA is involved in the anti-angiogenic activity of lenalidomide and might eventually upregulate ABCB1 expression, too. Patients and methods. Genotypes for SNPs were obtained through allele-specific (ASO) probes on germline DNA from peripheral blood. Minor allele frequencies (MAFs) were obtained and the Hardy-Weinberg equilibrium (HWE) was checked. Genotypes were used to infer individual haplotypes by Arlequin and Haploview softwares. Minimal residual disease (MRD) was assessed with ASO primers on either IGH or BCL-1/IGH rearrangements by RQ-PCR in bone marrow samples. TP53 disruption was identified by NGS targeting resequencing and copy number variation analysis. Clinical-biological correlations were screened by automated machine learning methods and validated by both Kaplan-Meier at univariate level and Cox models for multivariate analysis (MV). A logistic regression was implemented to investigate correlations between polymorphisms and MRD kinetics. Results. 278 out of 300 patients (93%) were fully genotyped. The MAF values of the SNPs were very similar to published data and the HWE was confirmed. Most notably, ABCB1 c.2677G&gt;T/A(W) and VEGFA c.2055A&gt;C were significantly associated to outcome and are thus described in this abstract. In the case of ABCB1, the three loci were in strong linkage disequilibrium (p&lt;0.001). 31% of patients were homozygous for ABCB1 wild type alleles (GG, "WT"), 53% heterozygous (GW, "HET") and 16% polymorphic on both chromosomes (WW, "POL"). 20% were VEGFA WT (AA), 47% HET (AC) and 33% POL (CC). PG did not impact on induction therapy and randomization rates of this trial, as superimposable polymorphism frequencies were described between the enrolled and randomized population. Conversely, both ABCB1 HET and POL and VEGFA HET/POL associated with higher MRD clearance rates vs WT after 6 months of LM (93% vs 71% and 91% vs 67%, respectively). Interestingly, the risk of MRD reappearance during LM was 86% lower for patients harboring either polymorphism vs WT (odds ratio 0.14, 95% CI 0.02-0.99; p&lt;0.05). Actually, ABCB1 HET/POL predicted for a more favorable PFS vs WT in LM (3yPFS 85% vs 69% p&lt;0.05, Fig.1A), as well as VEGFA HET/POL (3yPFS 85% vs 59% p&lt;0.01, Fig.1B). The two polymorphisms co-occurred in 57% of patients, being 12% ABCB1 HET/POL only, 23% VEGFA HET/POL and 8% ABCB1/VEGFA WT. Interestingly, patients with either polymorphism had superimposable outcome to patients in whom both co-occurred (Fig.1C). Finally, MV showed that either polymorphism was protective for PFS among randomized patients (HR=0.42; 95% CI 0.20-0.85; p&lt;0.05). According to this hypothesis, among the 17 ABCB1/VEGFA WT patients LM did not improved PFS vs OBS (Fig.1D), independently from TP53 disruption. Conclusions. The first PG data on LM after ASCT in MCL suggested that: 1) ABCB1 and VEGFA polymorphisms did not impact on the chemotherapeutic efficacy of FIL-MCL0208 trial; 2) both polymorphisms favored sustained MRD clearance during LM; 3) either polymorphism conferred a survival advantage during LM. Taken together, these observations hint that a variable excretion of lenalidomide through ABCB1 (heralded by SNPs), as well as an altered VEGFA pathway, could predict treatment efficacy. This observation might be very useful in the future to tailor lenalidomide therapy to MCL patients.

The Impact

Although alloHCT is an accepted salvage treatment in defined settings of poor-risk NHL, its potential benefit in these indications remains controversial because virtually all published studies are uncontrolled and restricted to patients who were actually able to undergo transplantation. Here, we aimed at assessing the impact of alloHCT by measuring its outcome from the time of donor search indication rather than from the time of transplant, thereby taking into account those patients who fail to proceed to allografting for any reason. Study design and patients : In a single centre retrospective analysis, course and outcome of all patients with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) mantle cell lymphoma (MCL) and peripheral T-cell lymphoma (PTCL) who were considered as having an alloHCT indication according to accepted guidelines between 2004 and 2018 were recorded. Primary endpoint was overall survival (OS) from start of donor search. A key secondary endpoint was comparison of OS from the 3-month landmark by donor availability. Accepted donors were matched related donors (MRD), 10/10 matched unrelated donors (MUD), 9/10 compatible unrelated donors (MMUD), and mismatched related donors (MMRD), with haplo donors being used at our institution only since 2014. Results : Altogether a donor search was initiated in 187 patients (DLBCL 32%, FL 17%, MCL 23%, PTCL 28%). Median age was 54 (19-69) years with 74% being male. Within a median time from diagnosis to search initiation of 1.1 (0.1-19) years, a median of 4 (1-9) treatment lines had been administered, including an autoHCT in 50%. 69% of the patients had active disease at the time of search initiation. Only 2 patients underwent donor search in 1st remission (for Richter transformation and hepatosplenic T cell lymphoma, respectively). With a median follow-up of 6.2 (0.6-15.9) years, OS at 5 years after search initiation for DLBCL, FL, MCL, and PTCL was 25%, 44%, 52%, and 50%, respectively (Fig 1). 171 patients (91%) were alive at the 3-month landmark. For these, an MRD (20%), MUD (44%), MMUD (25%), or MMRD (7%) could be identified in 96% of the cases. AlloHCT was performed in 72% of all 187 patients, and in 79% of the patients alive at the 3-month landmark, with a significantly lower rate in DLBCL (69%) compared to the other entities. In patients who were actually transplanted, 5-year OS from landmark for DLBCL, FL, MCL and PTCL was 32%, 63%, 62%, and 62%, respectively, whereas only 5 of the 36 patients (14%) alive at the 3-month landmark not undergoing alloHCT for any reason survived long term. Due to the low rate of unsuccessful searches, donor vs no-donor landmark survival analyses were not possible. Conclusions: Despite donor search now being successful in virtually all cases, 20-30% of those patients intended for alloHCT for NHL will never proceed to transplant. However, long-term OS by ITT does not seem substantially worse than alloHCT outcome observed in registry studies restricted to patients actually transplanted, with DLBCL appearing inferior to the other 3 entities. Patients surviving the 3-month landmark but not undergoing alloHCT for any reason have a poor outlook. These results may serve as benchmark for novel therapeutic options entering the NHL treatment landscape. Disclosures Luft: Neovii: Research Funding; JAZZ: Research Funding.

Abstract Abstract 152 Mantle cell lymphoma (MCL) is a rare B-cell malignancy characterized by the t(11;14) translocation. The European MCL network has demonstrated that a sequential R-CHOP/R-DHAP chemotherapy regimen prior to autologous stem cell transplantation (ASCT) provides better disease control than R-CHOP (Hermine et al, ASH 2010, abstract 110) and that molecular minimal residual disease (MRD) measured by IGH real-time quantitative polymerase chain reaction (PCR) before and after ASCT is an important prognostic factor to predict progression-free survival (PFS) (Pott et al. Blood. 2010;115(16):3215–23). Indeed, the use of high-dose aracytine upfront before ASCT is now recommended and molecular remission appears to be a major objective for future clinical trials in MCL. It therefore appeared interesting to appreciate response rates combining standard evaluation (Cheson 1999), FDG-PET imaging (Cheson 2007) and PCR techniques after rituximab plus upfront high-dose aracytine (R-DHAP) followed by ASCT. Response rates after 4 courses of R-DHAP were one of the objectives of the LyMa trial (NCT00921414). This trial is a randomized, open-label, phase III study that evaluates the efficacy of rituximab maintenance therapy in MCL patients aged between 18 and 66 years old, undergoing first-line treatment with 4xR-DHAP and exhibiting a response after ASCT (R-BEAM). Patients who do not reach a sufficient partial remission after R-DHAP are planned to receive 4 additional courses of R-CHOP before ASCT. The LyMa trial started in September 2008 and was designed to enroll 299 patients over a 4 years period. To date (August 2012), 295 patients have been included. Herein, we report response rates according to the combination of Cheson 1999 and 2007 criteria plus molecular response rates after 4xR-DHAP and after ASCT for the first 200 enrolled patients (last inclusion in August 2011). Results: One patient withdrew consent and the analysis is therefore on 199 patients. The cohort's median age is 57.2 years (range 29.7–65.7) and 41 patients are female (20%). At diagnosis, simplified MIPI was low in 104 cases (52%), intermediate in 55 (28%) and high in 40 (20%).Twenty-five patients (12.5%) presented with a blastoid variant. The panel of pathologist experts confirmed the diagnosis in all reviewed cases. Among the 199 evaluable patients, 182 (91%) received 4 courses of R-DHAP and 12 patients (all in PR according to Cheson 99 criteria) received 4 additional courses of R-CHOP because of insufficient clinical response after R-DHAP. Among these 12 patients, 5 reached CR/CRu after R-CHOP. Ultimately, 164 patients (82%) proceeded to ASCT (158 after R-DHAP and 6 after RDHAP/R-CHOP) and 154 (77.4%) have been randomized between rituximab maintenance or no maintenance. In an intention-to-treat (ITT) analysis and according to Cheson 1999 criteria, 152 patients (76.3%) reached CR (n=74) or CRu (n=78) after 4 courses of R-DHAP while 25 patients reached PR and 8 presented with SD/Prog. According to Cheson 2007 criteria (n= 170; PET not done in 17 cases and data missing in 12 cases), 129 patients reached CR while 41 patients remained FDG-TEP positive. Response rates according to Cheson 1999 and 2007 criteria for transplanted patients (n=164) were CR (n=109)/CRu (n=45) in 94% and CR in 84.5% (129 patients underwent FDG-PET after ASCT), respectively. Regarding MRD, diagnosis samples were available for 186/199 patients. Forty-one diagnosis samples have not yet been analyzed and 14 proved to be not informative. To date, the molecular response on peripheral blood (PB) after 4 courses of R-DHAP has been assessed in 103 cases and found negative in 80 cases and positive in 22 cases (not evaluable in one case). MRD on bone marrow (BM) after 4 courses of R-DHAP has been measured in 97 cases and found negative in 59 and positive in 36 (not evaluable in one case). After ASCT, PB and BM MRD were found negative in 91 patients (95 samples have been analyzed to date) and 67 (87 samples analyzed), respectively. Thus, in the LyMa trial,CR/CRu rates after only 4 courses of RDHAP, according to Cheson 1999 and 2007 criteria, are very high confirming the major anti-tumoral impact of high-dose aracytine upfront in MCL. In addition, these encouraging results seem to be confirmed at the molecular level strengthening the interest of an MRD-guided management of MCL patients. Results will be updated at the time of the meeting and patients' outcome according to disease status will be presented.

Abstract Eukaryotic translation initiation factor 5A (eIF5A) has been implicated in the regulation of cell proliferation, apoptosis, and inflammation, and is the only known protein to be modified by hypusination. Hypusinated eIF5A, the predominant form of eIF5A in cancer cells, is involved in cell survival and activation of inflammatory pathways. In contrast, accumulation of the unhypusinated form of eIF5A is associated with apoptosis and mutants of eIF5A that cannot be hypusinated (e.g. eIF5AK50R) are pro-apoptotic. SNS01-T was designed to treat B-cell cancers and consists of two active components: a plasmid DNA expressing the pro-apoptotic eIF5AK50R under the control of a B cell-specific promoter, and an siRNA against an untranslated region of native eIF5A mRNA. When these two components are combined with linear polyethyleneimine (PEI), the nucleic acids are condensed into nanoparticles for protection from degradation in the blood and enhanced cellular delivery. The mode of action of SNS01-T is siRNA-mediated inhibition of hypusinated eIF5A and simultaneous over-expression of pro-apoptotic eIF5AK50R to induce cell death. In vitro cell studies and in vivo xenograft studies have demonstrated the efficacy of this approach. The safety and tolerability of intravenous administration of SNS01-T is being investigated in a first-in-human Phase1b/2a study in patients with relapsed or refractory multiple myeloma (MM), mantle cell lymphoma (MCL) or diffuse large B cell lymphoma (DLBCL). Eligible patients are being enrolled sequentially into four cohorts at increasing doses. Each patient receives an intravenous infusion of SNS01-T twice weekly for 6 consecutive weeks. Eligible patients must have been diagnosed with MM according to IMWG criteria, or with MCL or DLBCL with histologic confirmation. Patients also must have measurable disease, have relapsed or refractory disease after two or more prior treatment regimens, have a life expectancy of at least 3 months, and not be eligible to receive any other standard therapy known to extend life expectancy. The primary objective is to evaluate the safety and tolerability of multiple escalating doses of SNS01-T. Secondary objectives include analysis of pharmacokinetics, immunogenicity, pro-inflammatory cytokines, and therapeutic efficacy. The required 3 patients per cohort have completed the dosing schedule in cohorts 1 and 2 from a total of 10 patients enrolled (9 patients with MM and 1 with DLBCL). Of the ten patients enrolled, four completed the full treatment period, two did not complete dosing but were evaluable for safety, and four (three in cohort 1 and one in cohort 2) discontinued treatment after fewer than 8 doses and were not evaluable. There were no drug-related serious adverse events or dose limiting toxicities in either cohort 1 or 2. In cohort 1 (0.0125 mg/kg SNS01-T), two of three evaluable patients did not progress on treatment and were considered stable at week 3 and week 6, the end of the dosing regimen. The third patient progressed after receiving 10 of the 12 doses and was evaluable for safety. In cohort 2 (0.05 mg/kg), 3 patients (2 with MM and 1 with DLBCL) were evaluable for safety. Stabilization of serum monoclonal protein levels was observed in one MM patient of cohort 2. Two patients (1 with MM and 1 with DLBCL) progressed after receiving 8 of the 12 doses and were evaluable for safety. Results from ongoing pharmacokinetic studies, immunogenicity studies, and quantification of pro-inflammatory cytokines will be discussed. The planned dose levels for the third and fourth groups are 0.2 and 0.375 mg/kg, respectively. The results to date of this first-in-human clinical trial indicate that SNS01-T can be administered safely and the MTD has not yet been reached (Clinical Trials.gov Identifier: NCT01435720).
