Incidence and Risk Factors for Central Nervous System Relapse in Very Elderly Patients over 80 with Diffuse Large B-Cell Lymphoma: A Retrospective Analysis of Two Lysa Studies

Abstract Background. The prevalence of diffuse large B-cell lymphoma (DLBCL) in patients aged over 80 years is reported to have tripled compared to patients in their sixties. Treating very elderly patients is particularly challenging given the likelihood of comorbidities and concerns over risks of toxicity. One of the most devastating and rapidly fatal complications in DLBCL is central nervous system (CNS) relapse. Most studies reporting incidence and risk factors of CNS relapse concern DLBCL patients under the age of 80 years, and little is known about CNS recurrence in the very elderly, aged over 80 years. CNS prophylaxis is rarely implemented in this population due to the burden of comorbidities, frequent antiplatelet or anticoagulant treatment along with renal failure and hypoalbuminemia, as well as potential prophylaxis toxicity of IV high dose methotrexate and/or the invasiveness of IT therapy. Aim. We retrospectively evaluated the incidence of CNS relapse, risk factors and specific survival in very elderly DLBCL patients aged 80 years Patients and Methods. Data were collected retrospectively from two multicentre, open-label, single arm phase II LYSA trials (LNH 03-7B (NCT01087424) between 2004 and 2007, LNH09-7B (NCT01195714) between 2009 and 2013) evaluating the addition of rituximab or ofatumumab to miniCHOP as front-line therapy. Results. A total of 270 elderly patients were included in the two trials, 150 treated with R-miniCHOP and 120 with O-miniCHOP. Median age was 83 years (range 79-95) and none received CNS prophylaxis. At inclusion, most patients (76%) presented with disseminated disease (Ann Arbor stage III or IV), and 37% had at least two extra-nodal sites. Overall 18% of patients had bone marrow involvement, while renal, adrenal, testis or cavum involvement was rare (4%, 2%, 3%, and 2%, respectively). After a median follow-up of 28.7 months (range 0.1-72.1), 8 (3%) cases of CNS relapse were reported. Median time between inclusion and CNS relapse was 19.2 months (range 3.2 - 32.6). Cumulative 1 and 2-year incidence of CNS relapse was 1.4% (95% CI 3.2-25.4) and 2.5% (95% CI 6.9-9.2), respectively. At inclusion, clinical characteristics of the CNS relapse patients were not significantly different from patients without relapse. At CNS relapse, all patients except one present a performance status ECOG > 2. neurological symptoms were either mild with loss of autonomy, asthenia, hearing impairment, urinary incontinence, or more prominent with delirium, aphasia, intracranial hypertension, or consciousness disorder. Treatment of CNS relapse was a supportive care based- treatment with corticosteroid only in 5 patients, radiation therapy in one patient, and chemotherapy for 2 patients including rituximab-temodal (5 cycles) in one patient and rituximab -aracytine-vepeside (2 cycles) for the other one. Patients survived for a median of 1.5 months after CNS relapse diagnosis (range, 0.4 to 4). The CNS international prognostic index (CNS-IPI) classified 33 (12%) patients in the low-risk group, 164 (62%) in the intermediate-risk group, and 71 (26%) in the high-risk group. The low-risk and intermediate-risk CNS-IPI groups showed 2-year rate of CNS disease of 3%, and the high-risk of 2.8% (p=0.9483). Conclusion. Incidence of CNS relapse in very elderly previously untreated patients is approximately 3% and is associated with a very poor survival. The absence of prophylaxis in this population did not appear to have a strong impact on CNS relapse incidence. Higher number of patients is warranted to identify risk factors for CNS relapse in this population Disclosures Coiffier: Pfizer: Consultancy, Membership on an entity's Board of Directors or advisory committees; Celgene: Consultancy, Membership on an entity's Board of Directors or advisory committees, Research Funding; Gilead: Consultancy, Membership on an entity's Board of Directors or advisory committees; Celltrion: Consultancy, Membership on an entity's Board of Directors or advisory committees; Novartis: Consultancy, Membership on an entity's Board of Directors or advisory committees; MorphoSys: Consultancy, Membership on an entity's Board of Directors or advisory committees.

Abstract Background: Diffuse large B-cell lymphoma (DLBCL) is the most common type of lymphoma. As the incidence of DLBCL increases with age, the number of elderly patients with DLBCL in our aging society continues to increase. However, patients aged ≥ 80 years old are often frail and carry multiple comorbidities, and are generally underrepresented in prospective clinical trials. Patients and Methods: 207 patients, age ≥80 years of age at diagnosis of de novo DLBCL were identified between 2002 and 2014 at MD Anderson Cancer Center and included in this retrospective analysis. Failure-free survival (FFS) and overall survival (OS) were examined; baseline characteristics and frontline therapy were evaluated for the association with survival outcomes by hazard ratio (HR). Results: Median age was 83 years (range 80-96). Fifty-five percent of the patients were male, 66% had advanced stage and 37% had poor performance status (ECOG PS≥2). Forty-five percent of the patients were IPI high-intermediate or high risk. Eighty patients (39%) were GCB and 49 patients (24%) were non-GCB subtype, respectively, according to the Hans criteria, with 78 patients lacking data for classification. Thirty-two patients (15%) had ≥4 scores by Charlson comorbidity index (CCI, Charlson 1987). Treatment received included R-CHOP (n=144, 70%), R-EPOCH (n=12, 6%), and non-anthracycline based therapies including R-CEOP and R-CVP (n=20, 10%). Sixteen patients (8%) did not receive any treatment due to deteriorated condition or patient's decision. Fifteen patients received other treatment such as radiation and rituximab monotherapy. With a median follow up of 38.1 months, 88 patients (43%) experienced progression/relapse and 123 patients (59%) died. Sixty-two patients (50%) died of lymphoma, 32 patients (26%) died of other co-morbid conditions while in remission and 17 patients (14%) died as a result of treatment complication during frontline therapy. Thirteen patients died during R-CHOP, 2 patients each died during R-CEOP or R-CVP and R-EPOCH, respectively, most were the result of infection or multi-organ failure. The 3-year FFS and OS were 55% and 54%, respectively. After 3-years, almost all deaths were attributed to other diseases (Figure A). Patients who received R-CHOP or R-EPOCH had a significantly longer FFS than patients who received R-CEOP or R-CVP (Figure B). CCI ≥4 was not associated with inferior FFS but was significantly associated with inferior OS. Multivariate analysis for OS adjusted by IPI and frontline treatment revealed that being female was associated with significantly longer OS (HR: 0.50, 95% CI, 0.33-0.75, p<0.01) and patients with beta-2 microglubulin >2.0mg/l had significantly inferior OS (HR: 7.21, 95% CI, 1.67-31.1, p=0.01). Conclusion: Patients with DLBCL aged ≥80 years who received anthracycline-based regimens such as R-CHOP or R-EPOCH had outcomes similar to younger patients with de novo DLBCL. Although they carry higher risks of therapy-related mortality, anthracycline-based regimens are moderately well tolerated, and their use should not be minimized based solely on age. Inclusion of very elderly patients in prospective clinical trials is warranted to identify the most effective management strategy for this population. Figure 1. Figure 1.

Risk Of Death

Abstract The international prognosis scoring system (IPSS) and the revised-IPSS were generated with data from 816 and 7,019 patients (pts) from academic centers with a median age of 69 and 71 years (y) respectively. As the median age of pts with MDS receiving care in Germany is 74.9 y and around a quarter of pts are older than 80 y, the aim was to evaluate the meaning of the IPSS and additional risk factors in the older population group. Methods: Pts with written informed consent could be included in the online-registry. Pts were eligible if a bone marrow examination had been performed and if basic data and the quarterly course of the disease were documented. Statistical analysis: Depending on the distributions of each variable frequency tables, means (SD), medians were calculated overall and stratified by age classes. Corresponding overall tests were performed (Chi-square, Kruskal-Wallis). Time dependent survival probabilities from MDS diagnosis were estimated by Kaplan Meier curves (compared using log rank test). Multiple Cox regression models were used to investigate associations between mortality risk and baseline risk factors. Variable selection was performed in the subpopulation of elderly pts based on univariate models and models including all prespecified variables (IPSS, sex, transfusion dependent at diagnosis (Tx at d), primary or secondary MDS, comorbidities). Mortality of pts subgroups was compared and age-sex-standardized with the German population 2013 as given in the Human Mortality Database (www.mortality.org, University of California Berkeley, Max Planck Institute for Demographic Research). Standardized mortality rates (SMR) and 95%-confidence intervals were estimated. Results: Between July 2009 and March 2016 (81 months) 2,118 pts from 90 institutions, mainly outpatient practices, were documented. The median age of the 843 (39.8%) female and 1,275 (60.2%) male pts was 74.9y (min-max: 26.5 - 94.2). 631 patients were excluded from analysis due to missing IPSS risk. The duration of observation, frequencies of IPSS, Tx at d, and the Charlson comorbidity index (CCI) are given in the table. Increased age and IPSS risk were significantly associated with the risk of death. An additional interaction between age and IPSS risk was significant (p=0.0198, Cox model, lower IPSS risk in increased age). In the subgroup of elderly patients (n=332, 147 died) after variable selection, IPSS, gender and Tx at d (22 missings) were significantly associated with the risk of death. Furthermore, even in the low risk group an elevated risk was estimated (SMR 1.773) compared to the normal population in the same age class. SMRs increase with higher IPSS risk. Analysis of comorbidities using CCI showed no significant association with mortality in the low risk group of the elderly patients (n=121, 44 died). Because of low sample sizes in the CCI subgroups the power is small, but even the survival curves did not show a clear trend (p= 0.497). Conclusion: IPSS risk and age are significantly associated with the risk of death. In elderly pts associated risk factors were IPSS, male gender and transfusion at diagnosis. Even the diagnosis of low risk MDS has a negative impact on life expectancy. Supported by an unrestricted grant from Celgene and Novartis. Table 1 Table 1. Figure Figure. Table 2 Table 2.

Minimal residual disease is now a powerfull surrogate marker to assess response to chemotherapy in acute myeloid leukemia (AML). In younger adults, NPM1 MRD has recently demonstrated to be a favorable predictive marker for EFS and OS independently of fms-like tyrosine kinase-3 internal tandem duplications (FLT3-ITD) status. However, there is very few datas regarding predictive value of NPM1 MRD in elderly patients treated with intensive chemotherapy. Moreover, numerous studies have suggested the negative impact of DNMT3a mutation in NPM1 AML patients, especially in those with concurrent FLT3-ITD mutation. In this study, we aimed to investigate the impact of DNMT3a status on post induction NPM1 MRD1 predictive value for survival in a retrospective cohort of AML patients aged over 60 years old treated intensively. A total of 138 patients treated for NPM1 mutated AML in two French institutions (Lyon, Lille) were analyzed retrospectively. Median age of the entire cohort was 66.1 years old (range 60-78.2). An FLT3-ITD mutation was evidenced in 52 of 138 patients (37.6%) with a median FLT3-ITD AR of 0.53 (range, 0.05-3). With a median follow-up of 19.61 months (0.07-128.4), the overall CR rate was 89.9% with no influence of DNMT3a or FLT3 mutational status on the probability of CR. In this elderly cohort of NPM1mut patients, a 4log reduction of NPM1 bone marrow (BM) MRD1 was associated with better outcome (median OS: NR vs 13.4 months, HR=0.35, p<0.01)(Figure A). Overall, DNMT3 status did not influence the probability of having a ≥ 4log MRD1 reduction after induction. However, only 9/44 (20.4%) FLT3-ITD patients reached ≥ 4log MRD1 reduction whereas 38/80 FLT3wt (47.5%) were good molecular responders (p<0.001). FLT3-ITD mutated patients who achieved a 4log reduction had a superior outcome compared to those who did not (HR=0.34; 95% CI, 0.16 to 0.70; P <0.001). Similarly, NPM1mut FLT3wt patients with a 4log reduction in NPM1 BM-MRD1 had a longer OS (3-year OS, 68.1%; 95% CI, 48.8 to 82.9) than those without good molecular response (3-year OS, 46.5%; 95% CI, 30.2 to 61.7)(Figure B). DNMT3a negative patients who achieved a 4log reduction had a superior outcome to those who did not reached at least a 4log reduction (HR=0.23; 95% CI, 0.07 to 0.72; P <0.001). However, postinduction NPM1 MRD1 reduction was not predictive of OS and leukemia free survival (LFS) in DNMT3amut patients. DNMT3amut patients has a very poor LFS which was even worst in poor NPM1 MRD1 responders compared to those who reached at least 4log reduction (median LFS: 8.3 months vs 17.4 months, HR = 0.48, 95% CI, 0.25-0.91, p=0.023)(Figure C). In multivariate analysis, only DNMT3a mutational status and a 4-log reduction in NPM1 BM-MRD were significantly associated with survival. Based on these results, we identified among NPM1 positive patients 3 groups with distinct prognosis, based on FLT3-ITD, DNMT3a status and NPM1 BM-MRD post induction response (NPM1 scoring system)(Figure D). When compared to ELN 2017 intermediate risk group (AUC=0.695), NPM1 scoring system (NPM1 SS) was more accurate for OS prediction in patients within intermediate (AUC=0.833) and unfavorable (AUC=0.863) NPM1 SS risk group. However, there was no significant difference in AUC between NPM1 SS favorable and ELN 2017 favorable risk group. These results confirm that post-induction NPM1 MRD1 is a reliable tool to assess disease outcome in elderly AML patients. However, the presence of DNMT3a also identify a subgroup of patients at very high risk of relapase, despite good molecular responses. As hematopoietic stem cell transplantation (HSCT) might improve OS in elderly patients, DNMT3a positive AML elderly patients should be considered for HSCT or post induction maintenance strategies, even within the favorable ELN risk group.

Introduction: CNS relapse of DLBCL is associated with poor prognosis. Estimated incidence varies between 1.9 and 8.4%1. The CNS-International prognostic index (IPI)2 help risk stratify and estimate the 2-year risk of CNS relapse in DLBCL patients treated with R-CHOP chemotherapy. CNS prophylaxis is indicated in patients with a high risk of CNS relapse (a score of ≥4 equated to a 10.2% risk). High-risk DLBCL patients outside the CNS-IPI system include double/triple-hit (MYC/BCL-2/BCL-6 translocations) lymphoma, HIV lymphoma, testicular lymphoma, primary cutaneous lymphoma-leg type, stage IE breast lymphoma3. IT methotrexate or cytarabine administered during the course of systemic chemotherapy has been the most widely employed method of CNS prophylaxis but there is paucity of data validating its efficacy. Aim: The primary aim of the study was to evaluate the CNS relapse rates in DLBCL patients who received CNS prophylaxis. Patients and Methods: This was a single-centre retrospective observational study conducted in a district general hospital. Data was extracted from the regional (Dorset Cancer Network) DLBCL database and laboratory reports for CSF analysis at the time of the first intrathecal chemotherapy. Medical records of patients with DLBCL who received CNS prophylaxis were evaluated for the following patient-related and disease-related demographics: age at diagnosis, gender, stage, systemic treatment, CNS prophylaxis, treatment response, remission duration, systemic relapse rates, CNS relapse rates and survival. CNS-IPI scores were retrospectively calculated and additional indications evaluated for patients who received CNS prophylaxis. Results: Between 2013 and 2018, 178 patients were diagnosed with DLBCL. All patients were treated with RCHOP chemo-immunotherapy. CNS prophylaxis was administered in 47 (26%) patients. Median age was 69 years (range 20-86 years) and 62% were males. All 47 patients (100%) received IT methotrexate as CNS prophylaxis, with 43 (91%) receiving all of the planned 4 doses of IT methotrexate 12.5 mg each. A CNS-IPI score of ³4 was present in 31 (66%) patients, and a score of 2-3 in 9 (19%) patients. Additional risk factors identified included testicular lymphoma in 3 patients, breast lymphoma in 2 patients and oropharyngeal lymphoma in 2 patients. Ten (21%) patients received their treatment at the outset with courses 1-4 of R-CHOP. Of the 47 patients who received CNS prophylaxis, 5 (10%) relapsed; all had isolated CNS lymphoma at relapse. Median time to CNS relapse was 25 months (range 12-36 months) from initial diagnosis of DLBCL. Median survival after CNS relapse was 5 months (range 2-9 months). Of the remaining 141 patients, 2 patients relapsed with isolated CNS lymphoma. Conclusion: Although the overall incidence was low (4%), CNS relapse was observed in 10% of high-risk patients all of whom received CNS prophylaxis with IT methotrexate. The efficacy of CNS prophylaxis with IT chemotherapy remains unproven. There is no randomised study to show that IT prophylaxis alone is effective. Current British guidelines recommend high-dose intravenous methotrexate over IT methotrexate if patient's physiological fitness and renal function are acceptable4. The median age in our cohort was 69 years which makes it challenging to deliver dose-intensive systemic therapy concurrently with intravenous high-dose methotrexate. The role of CNS prophylaxis in high-risk patients including its efficacy and safety in older patients need further evaluation in prospective randomised studies.

Abstract Background SAR3419 is a humanized anti-CD19 antibody conjugated to maytansin DM4, a potent cytotoxic agent. SAR3419 targets CD19, an antigen expressed in the majority of B cell non-Hodgkin lymphomas (NHL). The recommended dose for single agent SAR3419 was previously determined to be 55 mg/m2 administered IV every week for 4 weeks, then bi-weekly. In phase I, clinical activity was shown mainly in patients with follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). (Trial funded by Sanofi). Methods Patients (pts) with a CD20+ and CD19+ DLBCL relapsing or refractory (R/R) after at least 1 standard treatment including rituximab and not candidate for or who already underwent transplantation, were eligible. Refractory disease was defined as unresponsive to or progressing within 6 months of regimen completion. Fresh (or recent formalin-fixed, paraffin-embedded) biopsy was required before SAR3419 start. Pts received 375 mg/m2 of rituximab (R) IV and 55 mg/m² of SAR3419 on day 1, 8, 15, 22 (35-day cycle 1), followed by bi-weekly R and SAR3419 at the same doses for 2 additional 28-day cycles, provided there was no disease progression or other study discontinuation criteria met. The primary objective was the overall response rate (ORR) following Cheson 2007 criteria, with the first tumor assessment being done 42 days after the last study treatment administration. Secondary objectives were: safety, pharmacokinetics (PK), duration of response (DOR), progression free survival (PFS), overall survival (OS) and correlation of the antitumor and biological activity of the combination with tumor biomarker status. Results Fifty-three pts were enrolled, 52 treated. Median age was 66.5 years (range 38-85), 50% were male; 23%, 33% and 40% of patients had received 1, 2 or ≥3 prior chemo/immunotherapy regimens for DLBCL, respectively. Of the enrolled patients, 3.8% had received no prior regimen for DLBCL and therefore were excluded from primary analysis for efficacy. Seventy-three percent had stage III/IV disease, 59% had elevated lactate dehydrogenase (LDH), and 63% had bulky disease. Sixty percent were refractory to first regimen (primary refractory), 16% were refractory to last regimen and 24% were relapsed pts. The ORR in the per-protocol population (n=45) was 31.1% (80% confidence interval (CI): 22.0% to 41.6%). Among the 14 responders, 5 had progressed at the time of analysis, with duration of response beyond 6 months for 3 of them. The ORR was 58.3% (80% CI: 36.2% to 78.1%) for patients with relapsed DLBCL (n=12), 42.9% (80% CI: 17.0% to 72.1%) for pts refractory to last regimen (n=7) and 15.4% (80% CI: 6.9% to 28.4%) for primary refractory pts (n=26). Overall survival and PFS data are not yet mature. Biomarkers and PK data will be presented at the meeting. The most common (≥10%) all grades non-hematologic treatment-emergent adverse events (TEAEs) were asthenia (25.0%), nausea (21.2%), cough (19.2%), diarrhea (17.3%), weight decrease (17.3%), vomiting (15.4%), dyspnea (15.4%), abdominal pain (13.5%), back pain (13.5%), pyrexia (13.5%) and constipation (11.5%). Related grade 3-4 TEAEs were: 1 syncope, 1 bronchospasm, 2 neutropenia and 1 anemia. No TEAEs led to treatment discontinuation, no grade 3-4 peripheral neuropathy or grade 3-4 ocular events were observed. Two pts experienced grade 2 keratitis, both rapidly recovered with local treatment. Hematological toxicity was moderate, with grade 3-4 neutropenia and thrombocytopenia in 15.7% and 9.8% pts, respectively. No complications related to neutropenia were reported. Grade 3 transaminase increase was observed in 1 patient. Conclusions The combination of SAR3419 plus R showed moderate ORR in R/R DLBCL; however the study population was of poor prognosis (60% refractory to first line therapy). In the relapsed DLBCL patients a higher ORR was observed. SAR3419 plus R presented with a favorable safety profile. Further investigations on biomarker expression are ongoing to identify a sub-group of pts who could have better benefited from this combination.

Large B Cell Lymphoma

Abstract Background: Secondary CNS involvement (SCNS) is a detrimental complication seen in ~5% of patients with diffuse large B-cell lymphoma (DLBCL) treated with modern immunochemotherapy. Data from older series report short survival following SCNS, typically <6 months. However, data in patients that develop SCNS following primary therapy that contains a rituximab-based-regimen as well as the impact of more intensified treatment for SCNS are limited. Aims: The aims of this study were to i) describe the natural history of SCNS in a large cohort of patients treated with immunochemotherapy, and ii) determine prognostic factors after SCNS. Patients and methods: We performed a retrospective study of patients diagnosed with SCNS during or after frontline immunochemotherapy (R-CHOP or equivalently effective regimens). SCNS was defined as new involvement of the CNS (parenchymal, leptomeningeal, and/or eye) in patients without known CNS involvement at the time of first pathologic diagnosis of DLBCL. Patients were identified from local databases and/or regional/national registries in Denmark, Canada (British Columbia), Australia, Israel, US (University of Iowa/Mayo Clinic SPORE), and England (Guy's and St. Thomas' Hospital, London). Clinico-pathologic and treatment characteristics at the time of SCNS were collected from medical records. Results: In total, 281 patients with SCNS diagnosed between 2001 and 2016 were included. Median age at SCNS was 64 (range 20-93) years and male:female ratio was 1.3. SCNS occurred as part of first relapse in 244 (87%) patients and 112 (40%) had documented concurrent systemic disease at the time of SCNS. The median time from initial DLBCL diagnosis to SCNS was 9 months, which was similar for patients treated with (N=76, 27%) or without upfront CNS prophylaxis (N=205, 73%) (10 vs 9 Mo; P=0.3). The median post-SCNS OS was 4 months (interquartile range 2-13) and the 2yr survival rate was 20% (95% CI 15-25) for the entire cohort. Associations between clinicopathologic features, management strategy, and post-SCNS survival are shown in Table 1, which excludes patients who did not receive any treatment against SCNS, patients treated with steroids alone, and a patient with unavailable treatment information (n=43, 15%). In multivariable analysis, performance status >1, concurrent leptomeningeal and parenchymal involvement, SCNS developing before completion of 1st line treatment, and combined systemic and CNS involvement by DLBCL were associated with inferior outcomes. Upfront CNS prophylaxis did not influence post-SCNS OS. High-dose methotrexate (HDMTX) and/or platinum based treatment regimens (i.e. ICE, DHAP, or GDP [+/- IT treatment and/or radiotherapy], N=163) for SCNS were associated with reduced risk of death (HR 0.45 [0.32-0.62, P<0.01]). The 2yr post-SCNS survival for patients treated with HDMTX and/or platinum-based regimens (N=163) was 29% (95% CI 22-37). For patients with isolated parenchymal SCNS, single modality treatment with radiotherapy resulted in 2-yr OS of 19% (95% CI 8-35). For the subgroup of 49 patients treated with HDMTX- and/or platinum-based regimens for isolated SCNS after 1st line DLBCL treatment and with performance status 0 or 1, the 2yr post-SCNS survival was 46% (95% CI 31-59). Overall, 9% of the patients received HDT with ASCT as part of salvage therapy at the time of SCNS. Amongst 36 SCNS patients without systemic involvement and in CR following intensive treatment (HDMTX and/or platinum-based treatments), 11 patients consolidated with HDT had similar outcomes to 25 patients treated without consolidating HDT (P=0.9, Fig 1) Conclusions: Outcomes for patients with SCNS remain poor in this large international cohort of patients from the immunochemotherapy era. Combined parenchymal and leptomeningeal disease, presence of systemic disease concurrent with SCNS, performance status >1, and SCNS developing during first line treatment were independently associated with inferior OS. However, a significant fraction of patients with isolated SCNS after first line DLBCL treatment and with good performance status may achieve long-term remissions after intensive regimens for SCNS.

Abstract Background. R-CHOP is the standard first-line treatment for elderly patients with diffuse large B-cell lymphoma (DLBCL). However 30% of patients will relapse and 70% of relapsed patients will die within 2 years of diagnosis. The REMARC study (clinicalTrials.gov NCT01122472) is an international, multicenter, double-blind, randomized, placebo controlled, phase III trial that assessed the benefit of lenalidomide (LEN) maintenance after response to R-CHOP in patients aged 60 to 80 years with untreated DLBCL, FL3b or transformed lymphoma. Patients achieving CR or PR at the end of 6 or 8 cycles of R-CHOP21 or R-CHOP14 were stratified by CR/PR status and country and randomized 1:1 to receive 2 years of LEN maintenance (25 mg/day for 21 of every 28 days) or placebo (PBO). The primary endpoint of the study was progression-free survival (PFS). Secondary endpoints were safety, PR to CR conversion rate, and overall survival (OS). Diagnosis was retrospectively centrally reviewed. In patients with adequate samples, GCB/nonGCB profile was assessed by the Hans algorithm and GCB/ABC/unclassified profile was assessed using NanoString gene expression profiling technology. Methods. From 05/2009 to 05/2014, 784 patients were enrolled either before R-CHOP (n= 437) or after completion of 6 or 8 cycles of R-CHOP (n= 347). At the end of R-CHOP therapy, 650 patients were randomized to maintenance, either in CR (n= 495) or in PR (n= 152). Central review found that 3 patients were randomized in SD or PD, all in LEN arm. At time of diagnosis, median age was 68 y (range 58-80), 43.5% were older than 70 y, and 56% were male. aaIPI was low in 38.5% and high in 57.5% of patients (missing data 4%). COO analyses are ongoing for both Hans algorithm and NanoString technology. Results. With a median follow-up of 40 months, median PFS (according to independent centralized radiology review) was not reached in the LEN group versus 68 months in the PBO group (hazard ratio favoring the LEN group, 0.708 (95% CI 0.537-0.932; p=0.0135))(See Figure). In the LEN group, 18 patients (21%) converted from PR to CR during maintenance compared to 13 patients (14%) in the PBO group. Immature overall survival data did not show any benefit for LEN arm, a lack of difference not attributable to an excess of lymphoma relapse, secondary cancer or safety problems in LEN arm. Deaths generally occurred off study drug (median time from last dose of study drug to death was 277 days (range 20, 1291) in LEN arm and 334 (41, 1594) in control arm. During maintenance, the most common observed grade 3 or 4 AEs were neutropenia (56% vs. 22%), rash (5% vs. 1%), infections (8% vs. 6%), and thrombocytopenia (2.5% vs. 0.6%) in LEN and PBO arms, respectively. Dose adjustments were necessary in 72% of the LEN patients and 42% of PBO patients. 59% of patients stopped LEN and 40% stopped PBO for toxicity (p<0.001). Median number of cycles was 15 in LEN and 25 in PBO (p<0.001). Secondary primary malignancies occurred in 33 patients receiving LEN and in 42 patients on PBO. Conclusion. This analysis of the REMARC study shows that 2 years of LEN maintenance in patients responding to R-CHOP significantly improved PFS (primary endpoint) without an early significant impact on OS. The COO analysis is currently ongoing. This is the first report finding that using an immunomodulatory agent as maintenance therapy prolongs PFS for patients with DLBCL after first line treatment with R-CHOP. Figure 1.

Abstract Background Axicabtagene ciloleucel (axi-cel) is an autologous CD19-specific CAR T-cell therapy product that was FDA approved for the treatment of adult patients with relapsed or refractory large B-cell lymphoma after at least two lines of systemic therapy. In the pivotal ZUMA-1 study, the best overall response (ORR) and complete response (CR) rates observed in 108 patients treated with axi-cel were 82% and 58%, respectively. At a median follow-up of 15.4 months, 42% of the patients remain in ongoing response (Neelapu et al. N Eng J Med 2017). Analysis of efficacy outcomes in patients <65 years (N=81) and ³65 years (N=27) showed that the ORR and ongoing response at 12 months were comparable between the two subgroups (Neelapu et al. N Eng J Med 2017). Whether the safety is also comparable between the two subgroups is unknown. Here, we report safety outcomes in elderly patients (³65 years) with large B-cell lymphoma treated with axi-cel at our institution. Methods We retrospectively analyzed and reviewed the data from patients treated with axi-cel at our institution. Patients had a diagnosis of relapsed or refractory diffuse large B-cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma (PMBCL), high-grade B-cell lymphoma (HGBCL), and transformed follicular lymphoma (TFL). Patients were treated with conditioning chemotherapy with cyclophosphamide and fludarabine for 3 days followed by axi-cel infusion after 2 days of rest at a dose of 2 x 106 CAR+ T cells/kg body weight. Patients were monitored for toxicities for at least 7 days in the hospital after CAR T infusion and those who had at least 30 days of follow-up after axi-cel were considered to be evaluable for safety. Cytokine release syndrome (CRS) and neurological toxicity termed as CAR-related encephalopathy syndrome (CRES) were graded according to the CARTOX grading system (Neelapu et al. Nat Rev Clin Oncol 2018). Results A total of 61 patients with relapsed or refractory large B-cell lymphoma who received axi-cel at our institution were included. Of these, 44 (72%) patients were <65 years of age and 17 (28%) patients were ³65 years of age. The baseline characteristics of the patients are summarized in Table 1. ORR and CR rates at Day 30 were comparable between the two groups. CRS was common in both groups and was observed in 83% and 91% of the patients in the older and younger age groups, respectively. But most CRS events were grade 1-2. Grade 3 or higher CRS was observed in 18% vs. 11% in the older vs. younger age groups (P=0.67). One patient with a history of autoimmune disease in the elderly group died of hemophagocytic lymphohistiocytosis (HLH). CRES was observed in 58% and 71% of the patients in the older and younger age groups, respectively. Grade 3 or higher CRES was observed in 29% vs. 39% in the older vs. younger age groups (P=0.58). Median hospitalization period for axi-cel CAR T-cell therapy was comparable between the two groups. Conclusions Our results suggest that response rates are comparable between the elderly and younger age groups at day 30 after axi-cel therapy. Importantly, toxicities due to CRS and/or CRES after axi-cel CD19 CAR T cell therapy are comparable between the elderly (³65 years) and younger (<65 years) patients with relapsed or refractory large B-cell lymphoma.

Abstract Background. The recent advance of antiretroviral therapy decreased the morbidity of opportunistic infections. However, the incidence of HIV-associated lymphoma remains high. Also, the outcome of the HIV-associated lymphoma is unclear in the era of rituximab. In order to address these clinical questions, we performed a nation-wide epidemiological study. Methods. Patients with HIV-associated lymphoma were extracted from the database of Japanese society of hematology blood disease registry from January 2012 to December 2015. We analyzed the patient's age, sex, subtypes of lymphoma, the international prognostic index (IPI) for diffuse large B cell lymphoma, and overall survival. Results. Eighty-one patients were extracted from the database. Eighty patients were available for the survival analysis. Seventy-six (93.8%) patients of them were male. The median age was 52.5(25-88) year-old. However, there were two peaks of age; the first peak was 38-40-year-old and the second was 59-62-year-old. Sub-types of lymphomas were diffuse large B cell lymphoma (DLBCL)(48.1%), Burkitt lymphoma(19.8%), primary CNS lymphoma(8.6%), plasmablastic lymphoma(7.4%), peripheral T cell lymphoma(3.7%), Hodgkin's lymphoma(3.7%), primary effusion lymphoma(2.5%), MALT lymphoma(1.2%), Follicular lymphoma(1.2%) and Adult T cell lymphoma/leukemia(1.2%). Extra-nodal involvement at the diagnosis was observed in 61.7%. The involved sites were the brain, stomach, small bowel, colon, thyroid and the others. In DLBCL, the patients with IPI high and high-intermediate risk was 51.3%. The median observation period was 26 months. Estimated 3 years overall survival (OS) in all cases was 68.8+/-0.63%. Although there was no statistical significance, however, the 3 years, OS of Burkitt lymphoma tended to be better than that of DLBCL (84.6%+/-10.0 versus 67.7+/-8.8%). Log-rank analysis showed the OS in DLBCL patients with IPI high-intermediate and high risk was significantly worse than the patients with low, and low-intermediate risk (p<0.001). Estimated 3 years OS was 90+/-9.5% vs. 38.0+/-13.0%, respectively. The outcome of patients with primary CNS lymphoma remains poor, estimated 3 years OS was 45.7+/-22.4%. Conclusion. Our study showed diversity in the pathological subtype of HIV lymphoma. In the era of rituximab, the outcome seemed to be improved in patients with DLBCL and Burkitt lymphoma. However, the survival remains short in patients with poor prognostic factors and primary CNS lymphoma. Figure. Figure.

Abstract Introduction: The initial approach to elderly patients with Diffuse Large B-cell lymphoma (DLBCL) is usually based on the subjective judgment of the physician on the individual patient's ability to tolerate treatment with curative intent. "Comprehensive Geriatric Assessment" (CGA) is based on the use of the ADL (Activity of Daily Living), IADL (Instrumental ADL) and CIRS-G (Comorbidity Index Rating Scale for Geriatrics) scales and represents a tool to standardize initial patients fitness assessment and for planning systemic therapy. So far CGA has been rarely used in prospective studies and lacks a formal validation in patients with lymphoma. Objectives: FIL is conducting a prospective study with the aim of validating the use of CGA on a large series of elderly patients with DLBCL and to test a CGA based approach to the patient. CGA results will be used to define treatment goals that are the cure for the FIT subjects, and palliation for the FRAILs. Treatment goal for the UNFIT is cure with less toxic regimens. Methods: This study is conducted using a web based platform, accessible from the reserved area of the FIL website, to perform a quick and objective CGA evaluation of consecutive patients ≥ 65 years with untreated DLBCL. Patients younger than 80 years, without impairment of ADL and IADL and without severe comorbidities were considered FIT; those with intermediate fragility or those older than 80 years with FIT profile were classified as UNFIT (UN); those with severe impairment of ADL, IADL and CIRS and those older than 80 years with an UN profile were classified as FRAIL (FR). Informed consent was required to enrol patients in this study; the planned sample size was 1000 patients. Results: The study started in December 2013. At time of current analysis 792 patients have been registered by 45 centres: 328 (41%), 207 (26%), and 257 (33%) were classified as FIT, UN and FR, respectively. Median age was 77 years (yrs) (65-95); 73 (65-79), 80 (65-95) and 81 (65-95) yrs for FIT, UN and FR patients respectively; overall 65% were in stage III-IV. By univariate analysis, the three categories differed in terms of median age (p<0.001), B-symptoms (p=0.035), ECOG PS>1 (p<0.001), elevated LDH (p=0.035) and IPI score (p=0.004). Fourty-nine percent of cases were defined as UN only because of age (≥80 yrs); other reasons for UN were impairment of IADL, ADL in 30% and 18%, respectively. Only 3% of cases were UN due to CIRS (5-8 comorbidities of grade 2). Regarding FRAIL patients 27% of patients were classified in this group due to CIRS impairment, 24% and 18% due to IADL and ADL impairment, respectively. In remaining 31%, patients were FRAIL due to age ≥80 yrs (Figure 1). The most frequent altered ADL items among UN and FR patients were continence (15%) and bathing (30%), respectively; regarding IADL the most frequent altered items were buying and food preparation for either UN (19% and 12%) and FR (53% and 41%). Most frequent grade 3 comorbidities among the 257 FR patients were those referred to heart (16%), vascular system (9%), muscoloskelatal (7%), and genitourinary (5%). Data on planned treatment were available in 643 patients. Rituximab was used in all but 6 (2%), 18 (12%), and 35 (17%) FIT, UN, and FR cases. Treatment with curative intent (full doses R-CHOP-like regimens) was used in 94% and 65% of FIT and UNFIT cases; surprisingly curative intent was declared also in 38% of FRAIL cases. Six percent, 25% and 26% of FIT, UN and FR patients were treated with an attenuated R-CHOP-like immuno-chemotherapy regimens. Palliative regimens were used in 36% and 10% of FR and UN patients respectively. Conclusion: The preliminary data of Elderly Project showed that, with the CGA criteria as adopted in this study, the 59% of elderly patients with DLBCL at diagnosis were not FIT. Rituximab and doxorubicin containing regimen seems to be the reference treatment for FIT, UN and also for a significant proportion of FR patients but the actual value of using this approach for non-FIT patients is not clear and will be assessed with this project.
