Abstract: Metabolic flexibility has emerged as a critical determinant of CD8+ T-cell antitumor activity, yet the mechanisms driving the metabolic flexibility of T cells have not been determined. In this study, we investigated the influence of the nuclear cap-binding complex (CBC) adaptor protein ARS2 on mature T cells. In doing so, we discovered a novel signaling axis that endows activated CD8+ T cells with flexibility of glucose catabolism. ARS2 upregulation driven by CD28 signaling reinforced splicing factor recruitment to pre-mRNAs and affected approximately one-third of T-cell activation-induced alternative splicing events. Among these effects, the CD28-ARS2 axis suppressed the expression of the M1 isoform of pyruvate kinase in favor of PKM2, a key determinant of CD8+ T-cell glucose utilization, interferon gamma production, and antitumor effector function. Importantly, PKM alternative splicing occurred independently of CD28-driven PI3K pathway activation, revealing a novel means by which costimulation reprograms glucose metabolism in CD8+ T cells.

Abstract: Nodal peripheral T-cell lymphomas (PTCL), the most common PTCLs, are generally treated with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP)-based curative-intent chemotherapy. Recent molecular data have assisted in prognosticating these PTCLs, but most reports lack detailed baseline clinical characteristics and treatment courses. We retrospectively evaluated cases of PTCL treated with CHOP-based chemotherapy that had tumors sequenced by the Memorial Sloan Kettering Integrated Mutational Profiling of Actionable Cancer Targets next-generation sequencing panel to identify variables correlating with inferior survival. We identified 132 patients who met these criteria. Clinical factors correlating with an increased risk of progression (by multivariate analysis) included advanced-stage disease and bone marrow involvement. The only somatic genetic aberrancies correlating with inferior progression-free survival (PFS) were TP53 mutations and TP53/17p deletions. PFS remained inferior when stratifying by TP53 mutation status, with a median PFS of 4.5 months for PTCL with a TP53 mutation (n = 21) vs 10.5 months for PTCL without a TP53 mutation (n = 111). No TP53 aberrancy correlated with inferior overall survival (OS). Although rare (n = 9), CDKN2A-deleted PTCL correlated with inferior OS, with a median of 17.6 months vs 56.7 months for patients without CDKN2A deletions. This retrospective study suggests that patients with PTCL with TP53 mutations experience inferior PFS when treated with curative-intent chemotherapy, warranting prospective confirmation.

Abstract: We sought to define the genomic landscape of diffuse large B-cell lymphoma (DLBCL) by using formalin-fixed paraffin-embedded (FFPE) biopsy specimens. We used targeted sequencing of genes altered in hematologic malignancies, including DNA coding sequence for 405 genes, noncoding sequence for 31 genes, and RNA coding sequence for 265 genes (FoundationOne-Heme). Short variants, rearrangements, and copy number alterations were determined. We studied 198 samples (114 de novo, 58 previously treated, and 26 large-cell transformation from follicular lymphoma). Median number of GAs per case was 6, with 97% of patients harboring at least one alteration. Recurrent GAs were detected in genes with established roles in DLBCL pathogenesis (e.g. MYD88 , CREBBP , CD79B , EZH2 ), as well as notable differences compared to prior studies such as inactivating mutations in TET2 (5%). Less common GAs identified potential targets for approved or investigational therapies, including BRAF , CD274 (PD-L1), IDH2 , and JAK1/2 . TP53 mutations were more frequently observed in relapsed/refractory DLBCL, and predicted for lack of response to first-line chemotherapy, identifying a subset of patients that could be prioritized for novel therapies. Overall, 90% ( n  = 169) of the patients harbored a GA which could be explored for therapeutic intervention, with 54% ( n  = 107) harboring more than one putative target.

Abstract: Whole genome and exome sequencing studies have identified numerous genomic alterations in DLBCL, but these methods have limited applicability for the clinical care of lymphoma patients due to cost, specific tissue requirements, and laborious bioinformatic analysis. FoundationOne-Heme (FOH) is a novel next-generation sequencing platform designed to provide targeted assessment of the genomic landscape of hematologic malignancies, including identification of mutations within specific genes, copy number changes, and translocations. FOH can be performed on small quantities of formalin-fixed paraffin-embedded (FFPE) tissue, detect rare variants due to extensive depth of sequencing coverage, and rapidly provide results via streamlined bioinformatic interpretation. Here we report the first experience using this novel platform to evaluate the genetic landscape of DLBCL. Genomic DNA and total RNA were isolated from FFPE tissue on a cohort of 53 cases of DLBCL, including de novo (n=30), relapsed/refractory (n=12), and large cell transformation from low-grade lymphoma (n=11). The cohort included 25 cases with combined MYC and BCL2 overexpression by IHC (criteria for positivity: 〉 40% MYC, 〉 70% BCL2), of which only one had a known translocation involving MYC. Adaptor ligated sequencing libraries were captured by solution hybridization using two custom bait sets targeting 374 cancer-related genes and 24 genes frequently rearranged for DNA-seq, and 258 frequently-rearranged genes for RNA-seq. All captured libraries were sequenced to high depth (Illumina HiSeq), averaging 〉 658x for DNA and 〉 20,000,000 total pairs for RNA, to enable the sensitive and specific detection of genomic alterations. Significant non-synonomous variants were identified as mutations from the COSMIC database, amplifications of established oncogenes, or homozygous deletions and/or clear loss-of-function mutations of known tumor suppressors. The DNA sequencing component of FOH detected translocations in BCL2, BCL6, and MYC, while the RNA sequencing component detected fusion transcripts involving BLC6 and MYC, in agreement with independent cytogenetic analysis via karyotype and FISH where available. The assay detected copy number alterations of 44 different genes, most commonly amplification of REL (15%) or loss of CDKN2A/CDKN2B (17%). The most frequent alterations of known significance are detailed in Figure 1. The most commonly altered gene was CDKN2A, exhibiting either homozygous deletion or loss of function mutation in 28% of cases. Chromatin modifying factors (e.g. MLL2, CREBBP, EZH2) represented the most frequently altered biologic category with alterations occurring in 〉 50% of cases. Recurrent alterations in components of the Notch pathway (NOTCH1/2/4, FBXW7, SPEN), each predicted to activate the pathway, were identified in 23% of cases. Cell-of-origin was determined as per the Hans model using IHC for CD10, BCL6, and IRF4/MUM1; CD79B mutations were detected exclusively in non-GCB and EZH2 mutations were found exclusively in GCB-phenotype cases. Furthermore, IHC MYC+/BCL2+ de novo DLBCL cases (n=11) exhibited more frequent hypermutation of PIM1 (46%) compared with the 19 cases of IHC MYC-/BCL2- de novo DLBCL (11%). When comparing the various clinical categories, we found that mutations in tumor suppressors were significantly more common in relapsed/refractory than de novo DLBCL (47% vs 75%, p=0.02). Alterations in TP53 were most frequently observed in transformed lymphoma (55%). Our results demonstrate the feasibility of using a targeted next-generation sequencing platform on FFPE clinical specimens from patients with DLBCL as a means of providing an integrated analysis of gene mutations, copy number alterations, and translocations. This streamlined approach combines multiple molecular and cytogenetic tests into a single platform and uses a small amount of tissue to perform a multifaceted assessment of genomic alterations with potential diagnostic, prognostic, and therapeutic implications. Future efforts will be directed at analyzing additional cases of DLBCL to better establish the biologic and clinical significance of the observed genetic alterations, and to prospectively incorporate this novel platform to select patients for mechanism-based targeted therapy.

Abstract: Background: A variety of next-generation sequencing methods have been used to investigate the genomic landscape of primary lymphoma patient samples, including whole-genome, whole-exome, and RNA sequencing. In diffuse large B cell lymphoma (DLBCL), sequencing studies identified numerous genomic alterations (GAs) of potential clinical relevance, but the distribution and frequency of GAs have not been precisely determined. Discrepancies in existing data likely arise from variability in types of specimens examined, sequencing technologies employed, and depth of coverage utilized to identify GAs. In this study, we performed comprehensive DNA/RNA sequencing of genes known to be important across the spectrum of hematologic malignancies in order to determine the nature and prevalence of GAs with potential diagnostic, prognostic, or therapeutic implications in a cohort of 112 well-annotated clinical DLBCL cases. Methods: We performed hybridization capture of 405 cancer-related genes and 31 genes commonly rearranged in cancer (FoundationOne Heme) and 265 frequently rearranged genes for RNA-seq applied to ³50ng of DNA and sequenced to high, uniform coverage. Genomic alterations, including short variants (small indels and base substitutions), rearrangements, and copy number alterations, were determined. All captured libraries were sequenced to high depth (Illumina HiSeq), averaging 〉 500x for DNA and 〉 20,000,000 total pairs for RNA, to enable the sensitive and specific detection of GAs. Significant non-synonomous variants were identified as mutations from the COSMIC database, amplifications of established oncogenes, or homozygous deletions and/or clear loss-of-function mutations of known tumor suppressors. Results: GAs with diagnostic, prognostic, or therapeutic relevance were identified in 96% of cases, with a median of 5 (range 0 to 12) alterations per sample. Figure 1 shows the frequencies of different GAs. De novo DLBCL tended to exhibit fewer GAs (median 4) than relapsed/refractory (median 6) or transformed disease (median 6) (p=0.179; Wilcoxon rank sum). Compared with reported frequencies ranging from 5 to 44%, we detected alterations in CREBBP/EP300 in 21% of cases, with CREBBP mutations preferentially found in germinal-center B cell-like (GCB) compared to non-GCB DLBCL (26% vs. 8%; p=0.02; Pearson's chi-squared). Although previously described only in Burkitt lymphoma, we identified mutations in ID3 (L70P, P98R, Q100P) and TCF3 (N551K) in GCB-phenotype DLBCL cases with aggressive pathologic features and no MYC expression by IHC. Additional novel findings included alterations of genes involved in cellular metabolism in 18% of cases, including one IDH2 R172M mutation and two cases with SDHA L649fs* truncating mutations. We also identified several mutations more commonly found in solid tumors and leukemias, including BRAF V600E and KRAS G13D. With respect to genomic rearrangements, combined DNA/RNA capture and sequencing detected translocations/fusions in MYC, BCL2, and BCL6, which were concordant with cytogenetics/FISH analysis. We also identified rearrangements involving TBXL1XR1-P63, NOTCH2, SOCS1, and ETV6. Copy number alterations were detected in 26 different genes, including amplifications of CD274/PDCD1LG2 (PD-L1/PD-L2) (n=4) that were restricted to non-GCB cases. Alterations in TP53 were more frequently observed in transformed (42%) and relapsed/refractory (26%) compared to de novo DLBCL (12%; p=0.007; Pearson's chi-squared). TP53 mutations predicted for lack of response to chemotherapy, with chemo-refractory disease occurring in 48% of TP53-mutant patients compared to 10% of patients with intact TP53 (p=0.0004; Fisher's exact). Truncating mutations or deletions of RB1, albeit rare (5% of cases), were the most significant negative prognostic factor and were associated with therapeutic resistance and poor overall survival. Conclusions: Our results demonstrate the utility of comprehensive combined DNA/RNA next-generation sequencing as a promising method to identify clinically relevant GAs in clinical lymphoma specimens. This streamlined approach has the potential to combine multiple molecular and cytogenetic tests into a single platform. Future efforts will be directed at incorporating this approach both retrospectively and prospectively into clinical trials to identify predictive biomarkers to guide therapeutic decisions.

Abstract: Introduction: Gemcitabine/oxaliplatin (GemOx), with or without rituximab, is a frequently used treatment of relapsed or refractory (r/r) aggressive B-cell non-Hodgkin lymphoma (B-NHL), and is NCCN compendium-listed for both transplant-eligible and ineligible patients based upon results in small phase II clinical trials. Increasingly, GemOx is being accepted as a comparator arm for clinical trials in these populations. However, there is a paucity of observational data describing the effectiveness of R-GemOx in the treatment of r/r aggressive B-cell lymphoma. Methods: We conducted a retrospective analysis of the use of the GemOx regimen (with or without rituximab) in patients with r/r aggressive B-NHL at Memorial Sloan Kettering Cancer Center between January 2007 and January 2018, with a data cutoff of July 1, 2019. Data were extracted from the electronic medical record. Eligible diagnoses included diffuse large B-cell lymphoma and its subtypes (DLBCL); high-grade B-cell lymphomas (HGBL); transformed indolent B-cell lymphoma (tNHL) and grade 3B follicular lymphoma (FL3B). The primary objective of the study was to evaluate the activity of GemOx-based treatment in this patient population, as measured by overall response rate (ORR), complete response (CR) rate, progression-free survival (PFS), and overall survival (OS). CR was defined by a qualitatively negative 18-FDG-PET scan following completion of GemOx. PFS was defined as the time from start of therapy to disease progression or death, censoring patients at the time of initiation of any consolidative treatment. Similarly, OS was defined as the time from the start of GemOx until death or loss to follow-up. Results: Data were collected for 140 consecutive patients that received GemOx with (n=81) or without (n=59) rituximab in the treatment of a qualifying diagnosis (Table 1). Those treated had a median age at initiation of therapy of 69 (range, 30-92) and were predominantly male (58%). The median number of prior lines of therapy was 1 (range, 1-7), and the majority (97%) had received prior rituximab; few had received either prior autotransplant (11%) or allotransplant (1%). Regarding treatment delivered, the median number of cycles of therapy was 2 (range 1-12) with a mode of 2 (n=44, 31%). The ORR was 26% (n=37) with a CR rate of 15% (n=21). When evaluated by diagnosis, the ORR was 22% (n=19/88) in DLBCL, 40% (n=4/10) in HGBL, 35% (n=14/40) in tNHL, and 0% (n=0/2) in FL3B. Of the patients that responded to GemOx, 11 were successfully bridged to transplant (7 auto; 4 allo); two of those who went on to allotransplant had previously undergone autotransplant. Additionally, 3 patients went on to subsequently receive CAR-T therapy. Assessing the cohort overall, with a median follow-up of 48.1 months, PFS was only 1.4 months (95% CI: 1.3, 1.8), and median OS was 7.8 months (95% CI: 5.5, 12.0) (Figure 1). OS was longest for patients with tNHL at 10.2 months followed by DLBCL (7.5), HGBL (6.8) and FL3B (4.1) (Figure 2). Patients that received GemOx without rituximab in the setting of rituximab-refractory disease had a median OS of 4.1 months, less than that of 10.7 months for those receiving rituximab (p=0.052). However, there was no difference observed in PFS by inclusion of rituximab (1.6 months vs. 1.3 months, p=0.166). Patients with disease that was primary refractory following first-line therapy had a median OS of 4.5 months from initiation of GemOx, less than that of 10.8 months for patients that had achieved complete remission with first-line therapy (p=0.024). Patients that received GemOx as second-line therapy did not have a statistically significantly higher ORR (31% vs. 19%), OS (10.8 vs. 6.0 months), or PFS (1.7 vs, 1.4 months; all p=NS). In the subset of patients with DLBCL, there was again no significant difference in ORR (21% vs. 22%, p=NS), OS (8.5 vs. 6.1 months), or PFS (1.6 vs. 1.4 months; all p=NS). Conclusion: Despite compendium listing for both transplant-eligible and ineligible patients, and despite its adoption as a comparator arm in current and planned trials in r/r DLBCL, the real-world activity of GemOx with or without rituximab in the treatment of relapsed or refractory aggressive B-cell lymphoma is poor. Ongoing analysis is being conducted to seek clinical and histopathologic features associated with improved outcomes with GemOx.

Abstract: We conducted a phase II study evaluating pembrolizumab plus gemcitabine, vinorelbine, and liposomal doxorubicin (pembro-GVD) as second-line therapy for relapsed or refractory (rel/ref) classical Hodgkin lymphoma (cHL) (ClinicalTrials.gov identifier: NCT03618550 ). METHODS Transplant eligible patients with rel/ref cHL following first-line therapy were treated with two to four cycles of pembrolizumab (200 mg intravenous [IV], day 1), gemcitabine (1,000 mg/m 2 IV, days 1 and 8), vinorelbine (20 mg/m 2 IV, days 1 and 8), and liposomal doxorubicin (15 mg/m 2 , days 1 and 8), given on 21-day cycles. The primary end point was complete response (CR) following up to four cycles of pembro-GVD. Patients who achieved CR by labeled fluorodeoxyglucose-positron emission tomography (Deauville ≤ 3) after two or four cycles proceeded to high-dose therapy and autologous hematopoietic cell transplantation (HDT/AHCT). HDT/AHCT was carried out according to institutional standards, and brentuximab vedotin maintenance was allowed following HDT/AHCT. RESULTS Of 39 patients enrolled, 41% had primary ref disease and 38% relapsed within 1 year of frontline treatment. 31 patients received two cycles of pembro-GVD, and eight received four cycles. Most adverse events were grade 1 or two, whereas few were grade 3 and included transaminitis (n = 4), neutropenia (n = 4), mucositis (n = 2), thyroiditis (n = 1), and rash (n = 1). Of 38 evaluable patients, overall and CR rates after pembro-GVD were 100% and 95%, respectively. Thirty-six (95%) patients proceeded to HDT/AHCT, two received pre-HDT/AHCT involved site radiation, and 13 (33%) received post-HDT/AHCT brentuximab vedotin maintenance. All 36 transplanted patients are in remission at a median post-transplant follow-up of 13.5 months (range: 2.66-27.06 months). CONCLUSION Second-line therapy with pembro-GVD is a highly effective and well-tolerated regimen that can efficiently bridge patients with rel/ref cHL to HDT/AHCT.

Abstract: Nodal marginal zone lymphoma (NMZL) is a rare non-Hodgkin B-cell lymphoma that has historically been difficult to define, though is now formally recognized by the World Health Organization Classification. To better characterize the clinical outcomes of patients with NMZL, we reviewed a sequential cohort of 187 patients with NMZL to describe baseline characteristics, survival outcomes, and time-to-event data. Initial management strategies were classified into five categories: observation, radiation, anti-CD20 monoclonal antibody therapy, chemoimmunotherapy, or other. Baseline Follicular Lymphoma International Prognostic Index scores were calculated to evaluate prognosis. A total of 187 patients were analyzed. The five-year overall survival was 91% (95% confidence interval [CI] , 87-95), with a median follow-up time of 71 months (range, 8-253) among survivors. A total of 139 patients received active treatment at any point, with a median follow-up time of 56 months (range, 13-253) among survivors who were never treated. The probability of remaining untreated at five years was 25% (95% CI, 19-33). For those initially observed, the median time to active treatment was 72 months (95% CI, 49-not reached). For those who received at least one active treatment, the cumulative incidence of receiving a second active treatment at 60 months was 37%. Transformation to large B-cell lymphoma was rare, with a cumulative incidence of 15% at 10 years. In summary, our series is a large cohort of uniformly diagnosed NMZL with detailed analyses of survival and time to event analyses. We showed that NMZL commonly presents as an indolent lymphoma for which initial observation is often a reasonable strategy.
