Abstract: International audience; Before the Omicron era, the neutralizing antibody targeting the SARS-CoV2 Spike protein Sotrovimab has been shown to reduce the risk of COVID-19-related hospitalization in patients who are at high risk for progression (1, 2). We recently showed that early administration of Sotrovimab in Omicron-infected patients with very high-risk for progression was associated with a low rate of COVID-19-related hospitalization within one month after treatment administration (3%), and with no death (1). However, the dominance of the Omicron sublineage BA.2 led health agencies to suspend Sotrovimab emergency use authorizations because of its lower neutralizing ability in vitro compared to BA.1 sublineage (3, 4). Clinical efficiency of Sotrovimab to prevent COVID-19 related complications in high-risk patients with mild-to-moderate COVID-19 Omicron BA.2 remains unknown. Our aim was to compare the clinical and virological outcomes of Omicron BA.1 and BA.2-infected patients with mild-to-moderate COVID-19 who received 500 mg of Sotrovimab IV to prevent COVID-19-related complications.

Abstract: In the era of personalized treatment in multiple myeloma, high-risk patients must be accurately identified. The International Myeloma Working Group recommends using the Revised International Staging System (R-ISS) to pick out high-risk patients. The main purpose of our work was to explore the heterogeneity of outcome among R-ISS stage II patients assessing the impact of International Staging System (ISS) stage, chromosomal abnormalities and lactate dehydrogenase level in this subgroup. Data were collected from 1,343 patients up to 65 years old with newly diagnosed myeloma, enrolled in three clinical trials implemented by the Intergroupe Francophone du Myélome. All patients were eligible for intensive treatment. Patients in R-ISS stage II but ISS stage I had 1.6 times higher risk of death than patients in R-ISS stage I (adjusted hazard ratio=1.6; 95% confidence interval: 1.1-2.2; P=0.01) and patients in R-ISS stage II but with ISS stage III had a better overall survival than patients in R-ISS stage III (adjusted hazard ratio=0.7; 95% confidence interval: 0.4-0.9, P=0.02). However, among patients classified in R-ISS II, ISS stage and chromosomal abnormalities (del[17p] and t[4;14]) were still relevant prognostic factors for death. Dividing R-ISS stage II into three subgroups: ISS I with standard-risk chromosomal abnormalities, ISS II or III with standard-risk chromosomal abnormalities and patients with high-risk chromosomal abnormalities, median overall survival times were, respectively, not reached, 112 months and 71 months (P

Abstract: International audience; The automatic prediction of speech intelligibility can be seen as a growing and relevant alternative to the perceptual evaluations used clinically, which are known to be biased, variant and subjective. We propose an automatic way to regress an intelligibility score based on a recurrent model with a self-attention mechanism. This approach not only presented a high correlation of 0.87 when applied to a pseudo-word task designed for head and neck cancers, but also a significant decrease in error of more than 50%, when compared to previous approaches. Moreover, we have also studied the reliability of the same system when operating with smaller amounts of data at inference time. The results suggest that we can reduce the linguistic sample size to only 30% of the full sample, without losing performance. This aspect validates the reliability of using a smaller subset of data when predicting intelligibility, which can be extremely useful to prevent patient's fatigue by creating smaller batteries of clinical exams.

Abstract: WT1 overexpression is frequently identified in acute myeloid leukemia (AML) and has been reported to be a potential marker for monitoring measurable residual disease (MRD). We evaluated the use of postinduction WT1 MRD level as a prognostic factor, as well as the interaction between postinduction WT1 MRD response and the effect of allogeneic stem cell transplantation (allo-SCT) in the first complete remission (CR). In the ALFA-0702 trial, patients with AML, aged 18 to 59, had a prospective quantification of WT1 MRD. The occurrence of a WT1 MRD ratio >2.5% in bone marrow or >0.5% in peripheral blood was defined as MRDhigh, and ratios below these thresholds were defined as MRDlow. The prognostic value of MRD after induction chemotherapy was assessed in 314 patients in first CR by comparing the risk of relapse, the relapse-free survival (RFS), and the overall survival (OS). Interaction between MRD response and the allo-SCT effect was evaluated in patients by comparing the influence of allo-SCT on the outcomes of patients with MRDhigh with those with MRDlow. The results showed that patients with MRDhigh after induction had a higher risk of relapse and a shorter RFS and OS. The MRD response remained of strong prognostic value in the subset of 225 patients with intermediate-/unfavorable-risk AML who were eligible for allo-SCT, because patients with MRDhigh had a significantly higher risk of relapse resulting in worse RFS and OS. The effect of allo-SCT was higher in patients with MRDlow than in those with MRDhigh, but not significantly different. The early WT1 MRD response highlights a population of high-risk patients in need of additional therapy.

Abstract: International audience; Background During the 2005-2014 period, the GRAALL conducted the GRAALL-2005 trial in patients (pts) with Philadelphia chromosome (Ph)-negative ALL aged 18-59y. In this trial, all pts received a pediatric-inspired chemotherapy, whatever their age. Post-hoc analysis revealed an unacceptable TRM in pts aged 45-59y (Huguet et al. J Clin Oncol 2018; 36:2514-23). Allogeneic hematopoietic stem cell transplantation (HSCT) was offered in first complete remission (CR) to most CR pts, defined at high-risk (HR) by at least one baseline clinical or biological HR factor (CNS involvement, complex karyotype [≥5 abns.], low hypodiploidy/near triploidy, poor early blast clearance, late CR, as well as WBC ≥ 30x109/L, lack of CD10 expression, KMT2A rearrangement or TCF3::PBX1 fusion for B-cell precursor [BCP] ALL). Minimal residual disease (MRD) response was not considered for HSCT indication at that time.In the next GRAALL-2014 trial conducted in a similar population, we introduced two major changes in the treatment strategy. First, chemotherapy intensity (steroids, anthracycline and L-asparaginase) was reduced in pts aged 45-59y to decrease excessive TRM. Secondly, the indication for HSCT was modified, relying on IG/TR MRD response only (post-induction MRD ≥10-3 and/or post-consolidation MRD ≥10-4) while not on any former baseline HR criterion. Here, we compare the outcomes of the two trials, focusing on the impact of these two major evolutions.Patients & Methods A total of 743 pts treated in the GRAALL-2014 trial between 2015 and 2020 were compared to the 787 pts from the historical GRAALL-2005 trial, in terms of CR and induction death rates, rate of HSCT in CR1, cumulative incidence of TRM (CITRM) and relapse (CIR), relapse-free (RFS) and overall (OS) survival. It should be noted that two nested Phase 2 trials were introduced by amendment during the GRAALL-2014 course (in 2017 and 2018, respectively), aiming to evaluate post-remission addition of nelarabine and blinatumomab in 87 T-ALL and 94 BCP-ALL selected pts, respectively.Results Main patient characteristics, including age, gender, BCP/T-ALL, WBC, and historical baseline HR features, did not significantly differ between the two trial cohorts, even if CNS disease at diagnosis was more frequent in the 2014 cohort (12 vs 7%, p= 0.001).Outcome comparisons are shown in Table 1. Overall, the induction death rate was significantly reduced in the GRAALL-2014 (3 vs 6%, p= 0.005). As expected, this was only observed in pts aged 44-59y (3 vs 11%, p= 0.001), in whom dose-intensity reduction also translated into a higher need for second induction course (9 vs 5%, p= 0.05) eventually resulting in a higher CR rate (92 vs 86%, p= 0.05). Due to the newly introduced MRD-based stratification, the rate of pts with HSCT indication was markedly reduced (30 vs 65%, p

Abstract: We present the results of a phase 2 study evaluating the combination of obinutuzumab + idelalisib in relapsed/refractory (R/R) Waldenström macroglobulinemia (WM). The goal was to determine the safety and efficacy of a fixed-duration chemotherapy-free treatment. During the induction phase, patients received idelalisib + obinutuzumab for 6 cycles, followed by a maintenance phase with idelalisib alone for ≤2 years. Forty-eight patients with R/R WM were treated with the induction combination, and 27 patients participated in the maintenance phase. The best responses, reached after a median of 6.5 months (interquartile range, 3.4-7.1; range, 2.6-22.1 months), were very good partial response in 5 patients, partial response in 27 patients, and minor response in 3 patients, leading to overall response rate and major response rate estimates of 71.4% (95% confidence interval [CI], 56.7-83.4) and 65.3% (95% CI, 50.4-78.3), respectively. With a median follow-up of 25.9 months, median progression-free survival was 25.4 months (95% CI, 15.7-29.0). Univariate analysis focusing on molecular screening found no significant impact of CXCR4 genotypes on responses and survivals but a deleterious impact of TP53 mutations on survival. Although there was no grade 5 toxicity, 26 patients were removed from the study because of side effects; the most frequent were neutropenia (9.4%), diarrhea (8.6%), and liver toxicity (9.3%). The combination of idelalisib + obinutuzumab is effective in R/R WM. Nonetheless, the apparent lack of impact of genotype on outcome could give new meaning to targeting of the phosphatidylinositol 3-kinase pathway in WM. This trial was registered at www.clinicaltrials.gov as #NCT02962401.

Abstract: International audience; In order to improve the outcome observed with azacitidine (AZA) in higher-risk Myelodysplastic syndrome (MDS), its combination with other drugs in MDS must be evaluated. So far, no combination has not been shown to be more effective than AZA alone. AZA-PLUS was a phase II trial that, in a "pick a winner" approach, randomly assigned patients with higher-risk MDS, CMML and low blast count AML to: AZA; AZA plus lenalidomide; AZA plus Valproic Acid or AZA plus Idarubicin. 322 patients were included. After six\,cycles, 69 (21.4%) CR\,+\,PR were observed with no benefit from any combination. Median EFS and OS were 17.2 and 19.7\,months in the whole cohort, respectively, with no difference across randomised arms. Infection and rates of hospitalisation during the first six\,cycles were higher in the AZA-LEN And AZA-IDA arm, related to increased myelosuppression. Factors associated with better response were IPSS, favourable or intermediate karyotype, haemoglobin, lower circulating blast count, fibrinogen level and lower LDH, while poorer survival was seen in therapy-related MDS and, in the case of TP53, PTPN11 or CSF3R mutation. The combinations used did not improve the outcome obtained with AZA alone. However, our "pick a winner" randomised strategy may remain useful with potentially more active drugs to be tested in combination with AZA.

Abstract: International audience; Background: Lymphomas are costly diseases that suffer from a lack of detailed economic information, notably in a real-world setting. Decision-makers are increasing the search for Real-World Evidence (RWE) to assess the impact, in real-life, of healthcare management and to support their public decisions. Thus, we aimed to assess the real-world net costs of the active treatment phases of adult Hodgkin Lymphoma (HL), Follicular Lymphoma (FL) and Diffuse Large B Cell Lymphoma (DLBCL).Methods: We performed a retrospective cohort study using population-based data from a national representative sample of the French population covered by the health insurance system. Cost analysis was performed from the French health insurance perspective and took into account direct and sick leave compensation costs (e2,018). Healthcare costs were studied over the active treatment phase. We used multivariate modeling to adjust cost differences between lymphoma subtypes.Results: Analyses were performed on 224 lymphoma patients and 896 controls. The mean additional monthly costs due to HL, FL and DLBCL patients were respectively e5,188, e3,242 and e7,659 for the active treatment phase. The main additional cost driver was principally inpatient stay (hospitalization costs and costly cancer-related drugs), followed by outpatient medication and productivity loss. When adjusted, DLBCL remains significantly the most costly lymphoma subtype.Conclusion: This study provides an accurate assessment of the main lymphoma subtypes related cost with high magnitude of details in a real-world setting. We underline where potential cost saving could be realized via the use of biosimilar medication, and where lymphoma management could be improved with the early management of adverse events.

Abstract: Background Previous studies have suggested that lymphoma survivors commonly display altered Health-Related Quality of Life (HRQoL). Because these were predominantly cross-sectional studies, the dynamic of events as well as the factors which influence HRQoL remain to be determined. Methods We conducted a prospective study on a cohort of 204 Hodgkin and non-Hodgkin lymphoma survivors who remained disease-free 2 years after undergoing chemotherapy (referred to the M0-M12-M24 periods). Results We found that although Physical and Mental Component Scores (PCS and MCS) of HRQoL significantly improved from M0 to M24 in the vast majority of patients (favorable group), approximately 20% of patients displayed severe alterations in HRQoL (global SF-36 scores Conclusions Although the HRQoL of lymphoma survivors generally improved over time, persistent and severe HRQoL alterations still affected approximately one fifth of patients, resulting in important social consequences. This specific group, which presents with identifiable risk factors, may benefit from early, targeted psycho-social support.

Abstract: International audience; PurposeTo assess the incidence of BCR‐ABL kinase domain (KD) mutation detection and its prognostic significance in chronic phase chronic myeloid leukemia (CP‐CML) patients treated with tyrosine kinase inhibitors (TKIs).Patients and MethodsWe analyzed characteristics and outcome of 253 CP‐CML patients who had at least one mutation analysis performed using direct sequencing. Of them, 187 patients were early CP (ECP) and 66 were late CP late chronic phase (LCP) and 88% were treated with Imatinib as first‐line TKI.ResultsOverall, 80 (32%) patients harbored BCR‐ABL KD mutations. A BCR‐ABL KD mutation was identified in 57% of patients, who progressed to accelerated or blastic phases (AP‐BP), and 47%, 29%, 35%, 16% and 26% in patients in CP‐CML at the time of mutation analysis who lost a complete hematologic response, failed to achieve or loss of a prior complete cytogenetic and major molecular response, respectively.Overall survival and cumulative incidence of CML‐related death were significantly correlated with the disease phase whatever the absence or presence of a mutation was and for the latter the mutation subgroup (T315I vs P‐loop vs non‐T315I non‐P‐loop) (P

Abstract: Purpose Among metastatic breast cancer (MBC) patients, those with a triple-negative breast cancer phenotype (mTNBC) have the worst prognosis, but the benefit of chemotherapy beyond second line on outcome remains uncertain. The purpose of this study was to identify predictive factors of outcome after third- or fourth-line chemotherapy. Methods The ESME-MBC database is a French prospective real-life cohort with homogeneous data collection, including patients who initiated first-line treatment for MBC (2008–2016) in 18 cancer centers. After selection of mTNBC cases, we searched for independent predictive factors (Cox proportional-hazards regression models) for overall survival (OS) on third- and fourth-line chemotherapy (OS3, OS4). We built prognostic nomograms based on the main prognostic factors identified. Results Of the 22,266 MBC cases in the ESME cohort, 2903 were mTNBC, 1074 (37%) and 598 (20%) of which had received at least 3 or 4 lines of chemotherapy. PFS after first- and second-line chemotherapy (PFS1, PFS2) and number of metastatic sites ≥3 at baseline were identified by multivariate analysis as prognostic factors for both OS3 (HR = 0.76 95%CI[0.66–0.88], HR = 0.55 95%CI[0.46–0.65], HR = 1.36 95%CI[1.14–1.62], respectively), and OS4 (HR = 0.76 95%CI[0.63–0.91], HR = 0.56 95%CI[0.45–0.7], HR = 1.37 95%CI[1.07–1.74]), respectively. In addition, metastasis-free interval was identified as a prognostic factor for OS3 (p = 0.01), while PFS3 influenced OS4 (HR = 0.75 95%CI[0.57–0.98]). Nomograms predicting OS3 and OS4 achieved a C-index of 0.62 and 0.61, respectively. Conclusion The duration of each previous PFS is a major prognostic factor for OS in mTNBC patients receiving third- or fourth-line chemotherapy. The clinical utility of nomograms including this information was not demonstrated., Highlights • After 3rd- or 4th-line therapy, PFS remained linear in the majority of women with metastatic triple-negative breast cancer. • The duration of each previous PFS had an impact on the OS associated with subsequent lines. • PFS2 was more strongly predictive of outcome than PFS1 for third-line therapy. • PFS2 and PFS3 had an impact on outcome irrespective of PFS1 for fourth-line therapy. • The clinical utility of nomograms including duration of each previous PFS to predict OS was not sufficient.

Abstract: International audience; High-definition transcriptomic studies through single-cell RNA sequencing (scRNA-Seq) have revealed the heterogeneity and functionality of the various microenvironments across numerous solid tumors. Those pioneer studies have highlighted different cellular signatures correlated with clinical response to immune checkpoint inhibitors. scRNA-Seq offers also a unique opportunity to unravel the intimate heterogeneity of the ecosystems across different lymphoma entities. In this review, we will first cover the basics and future developments of the technology, and we will discuss its input in the field of translational lymphoma research, from determination of cell-of-origin and functional diversity, to monitoring of anti-cancer targeted drugs response and toxicities, and how new improvements in both data collection and interpretation will further foster precision medicine in the upcoming years.

Abstract: A multistage model instructed by a large dataset (knowledge bank [KB] algorithm) has recently been developed to improve outcome predictions and tailor therapeutic decisions, including hematopoietic stem cell transplantation (HSCT) in acute myeloid leukemia (AML). We assessed the performance of the KB in guiding HSCT decisions in first complete remission (CR1) in 656 AML patients younger than 60 years from the ALFA-0702 trial (NCT00932412). KB predictions of overall survival (OS) were superior to those of European LeukemiaNet (ELN) 2017 risk stratification (C-index, 68.9 vs 63.0). Among patients reaching CR1, HSCT in CR1, as a time-dependent covariate, was detrimental in those with favorable ELN 2017 risk and those with negative NPM1 minimal residual disease (MRD; interaction tests, P = .01 and P = .02, respectively). Using KB simulations of survival at 5 years in a scenario without HSCT in CR1 (KB score), we identified, in a similar time-dependent analysis, a significant interaction between KB score and HSCT, with HSCT in CR1 being detrimental only in patients with a good prognosis based on KB simulations (KB score ≥40; interaction test, P = .01). We could finally integrate ELN 2017, NPM1 MRD, and KB scores to sort 545 CR1 patients into 278 (51.0%) HSCT candidates and 267 (49.0%) chemotherapy-only candidates. In both time-dependent and 6-month landmark analyses, HSCT significantly improved OS in HSCT candidates, whereas it significantly shortened OS in chemotherapy-only candidates. Integrating KB predictions with ELN 2017 and MRD may thus represent a promising approach to optimize HSCT timing in younger AML patients.

Abstract: International audience; γδ T lymphocytes diverge from conventional T CD8 lymphocytes for ontogeny, homing, and antigen specificity, but whether their differentiation in tumors also deviates was unknown. Using innovative analyses of our original and ~150 published single-cell RNA sequencing datasets validated by phenotyping of human tumors and murine models, here we present the first high-resolution view of human γδ T cell differentiation in cancer. While γδ T lymphocytes prominently encompass TCRVγ9 cells more differentiated than T CD8 in healthy donor's blood, a different scenario is unveiled in tumors. Solid tumors and lymphomas are infiltrated by a majority of TCRVγnon9 γδ T cells which are quantitatively correlated and remarkably aligned with T CD8 for differentiation, exhaustion, gene expression profile, and response to immune checkpoint therapy. This cancer-wide association is critical for developing cancer immunotherapies.

Abstract: International audience; In patients with isocitrate dehydrogenase (IDH)-mutated acute myeloid leukemia (AML) treated by intensive chemotherapy (IC), prognostic significance of co-occurring genetic alterations and allogeneic hematopoietic stem cell transplantation (HSCT) are of particular interest with the advent of IDH1/2 mutant inhibitors. We retrospectively analyzed 319 patients with newly diagnosed AML (127 with IDH1, 135 with IDH2R140, and 57 with IDH2R172 mutations) treated with IC in 3 Acute Leukemia French Association prospective trials. In each IDH subgroup, we analyzed the prognostic impact of clinical and genetic covariates, and the role of HSCT. In patients with IDH1 mutations, the presence of NPM1 mutations was the only variable predicting improved overall survival (OS) in multivariate analysis (P< .0001). In IDH2R140-mutated AML, normal karyotype (P = .008) and NPM1 mutations (P = .01) predicted better OS. NPM1 mutations were associated with better disease-free survival (DFS; P = .0009), whereas the presence of DNMT3A mutations was associated with shorter DFS (P = .0006). In IDH2R172-mutated AML, platelet count was the only variable retained in the multivariate model for OS (P = .002). Among nonfavorable European LeukemiaNet 2010-eligible patients, 71 (36%) underwent HSCT in first complete remission (CR1) and had longer OS (P = .03) and DFS (P = .02) than nontransplanted patients. Future clinical trials testing frontline IDH inhibitors combined with IC may consider stratification on NPM1 mutational status, the primary prognostic factor in IDH1- or IDH2R140-mutated AML. HSCT improve OS of nonfavorable IDH1/2-mutated AML and should be fully integrated into the treatment strategy.

Abstract: Background Ibrutinib, an irreversible Bruton Tyrosine Kinase (BTK) inhibitor, has revolutionized Chronic Lymphocytic Leukemia (CLL) treatment, but resistances to ibrutinib have emerged, whether related or not to BTK mutations. Patterns of CLL evolution under ibrutinib therapy are well characterized for the leukemic cells but not for their microenvironment. Methods Here, we addressed this question at the single cell level of both transcriptome and immune-phenotype. The PBMCs from a CLL patient were monitored during ibrutinib treatment using Cellular Indexing of Transcriptomes and Epitopes by sequencing (CITE-Seq) technology. Results This unveiled that the short clinical relapse of this patient driven by BTK mutation is associated with intraclonal heterogeneity in B leukemic cells and up-regulation of common signaling pathways induced by ibrutinib in both B leukemic cells and immune cells. This approach also pinpointed a subset of leukemic cells present before treatment and highly enriched during progression under ibrutinib. These latter exhibit an original gene signature including up-regulated BCR, MYC-activated, and other targetable pathways. Meanwhile, although ibrutinib differentially affected the exhaustion of T lymphocytes, this treatment enhanced the T cell cytotoxicity even during disease progression. Conclusions These results could open new alternative of therapeutic strategies for ibrutinib-refractory CLL patients, based on immunotherapy or targeting B leukemic cells themselves.

Abstract: Autophagy has been associated with oncogenesis with one of its emerging key functions being its contribution to the metabolism of tumors. Therefore, deciphering the mechanisms of how autophagy supports tumor cell metabolism is essential. Here, we demonstrate that the inhibition of autophagy induces an accumulation of lipid droplets (LD) due to a decrease in fatty acid β-oxidation, that leads to a reduction of oxidative phosphorylation (OxPHOS) in acute myeloid leukemia (AML), but not in normal cells. Thus, the autophagic process participates in lipid catabolism that supports OxPHOS in AML cells. Interestingly, the inhibition of OxPHOS leads to LD accumulation with the concomitant inhibition of autophagy. Mechanistically, we show that the disruption of mitochondria–endoplasmic reticulum (ER) contact sites (MERCs) phenocopies OxPHOS inhibition. Altogether, our data establish that mitochondria, through the regulation of MERCs, controls autophagy that, in turn finely tunes lipid degradation to fuel OxPHOS supporting proliferation and growth in leukemia., How autophagy supports tumor cell metabolism is not fully clear. Here, the authors show that autophagy regulates lipid availability to support mitochondrial oxidative metabolism through mitochondria-endoplasmic reticulum contact sites, necessary for cell proliferation in AML.

Abstract: International audience; Dendrogenin A (DDA) is a mammalian cholesterol metabolite that displays potent antitumor properties on acute myeloid leukemia (AML). DDA triggers lethal autophagy in cancer cells through a biased activation of the oxysterol receptor LXRβ, and the inhibition of a sterol isomerase. We hypothesize that DDA could potentiate the activity of an anticancer drug acting through a different molecular mechanism, and conducted in vitro and in vivo combination tests on AML cell lines and patient primary tumors. We report here results from tests combining DDA with antimetabolite cytarabine (Ara-C), one of the main drugs used for AML treatment worldwide. We demonstrated that DDA potentiated and sensitized AML cells, including primary patient samples, to Ara-C in vitro and in vivo. Mechanistic studies revealed that this sensitization was LXRβ-dependent and was due to the activation of lethal autophagy. This study demonstrates a positive in vitro and in vivo interaction between DDA and Ara-C, and supports the clinical evaluation of DDA in combination with Ara-C for the treatment of AML.

Abstract: Non-Hodgkin B-cell lymphomas (B-NHLs) are a highly heterogeneous group of mature B-cell malignancies. Their classification thus requires skillful evaluation by expert hematopathologists, but the risk of error remains higher in these tumors than in many other areas of pathology. To facilitate diagnosis, we have thus developed a gene expression assay able to discriminate the seven most frequent B-cell NHL categories. This assay relies on the combination of ligation-dependent RT-PCR and next-generation sequencing, and addresses the expression of more than 130 genetic markers. It was designed to retrieve the main gene expression signatures of B-NHL cells and their microenvironment. The classification is handled by a random forest algorithm which we trained and validated on a large cohort of more than 400 annotated cases of different histology. Its clinical relevance was verified through its capacity to prevent important misclassification in low grade lymphomas and to retrieve clinically important characteristics in high grade lymphomas including the cell-of-origin signatures and the MYC and BCL2 expression levels. This accurate pan-B-NHL predictor, which allows a systematic evaluation of numerous diagnostic and prognostic markers, could thus be proposed as a complement to conventional histology to guide the management of patients and facilitate their stratification into clinical trials.

Abstract: Ibrutinib is used for the treatment of chronic lymphocytic leukemia and other lymphoid malignancies. The aim of this work is to develop a population pharmacokinetic model for ibrutinib and its dihydrodiol metabolite to quantify pharmacokinetic inter- and intra-individual variability, to evaluate the impact of several covariates on ibrutinib pharmacokinetic parameters, and to examine the relationship between exposure and clinical outcome. Patients treated with ibrutinib were included in the study and followed up for 2 years. Pharmacokinetic blood samples were taken from months 1 to 12 after inclusion. Ibrutinib and dihydrodiol-ibrutinib concentrations were assessed using ultra-performance liquid chromatography tandem mass spectrometry. A population pharmacokinetic model was developed using NONMEM version 7.4. A total of 89 patients and 1501 plasma concentrations were included in the pharmacokinetic analysis. The best model consisted in two compartments for each molecule. Absorption was described by a sequential zero first-order process and a lag time. Ibrutinib was either metabolised into dihydrodiol-ibrutinib or excreted through other elimination routes. A link between the dosing compartment and the dihydrodiol-ibrutinib central compartment was added to assess for high first-pass hepatic metabolism. Ibrutinib clearance had 67% and 47% inter- and intra-individual variability, respectively, while dihydrodiol-ibrutinib clearance had 51% and 26% inter- and intra-individual variability, respectively. Observed ibrutinib exposure is significantly higher in patients carrying one copy of the cytochrome P450 3A4*22 variant (1167 ng.h/mL vs 743 ng.h/mL, respectively, p = 0.024). However, no covariates with a clinically relevant effect on ibrutinib or dihydrodiol-ibrutinib exposure were identified in the PK model. An external evaluation of the model was performed. Clinical outcome was expressed as the continuation or discontinuation of ibrutinib therapy 1 year after treatment initiation. Patients who had treatment discontinuation because of toxicity had significantly higher ibrutinib area under the curve (p = 0.047). No association was found between cessation of therapy due to disease progression and ibrutinib area under the curve in patients with chronic lymphocytic leukemia. For the seven patients with mantle cell lymphoma studied, an association trend was observed between disease progression and low exposure to ibrutinib. We present the first population pharmacokinetic model describing ibrutinib and dihydrodiol-ibrutinib concentrations simultaneously. Large inter-individual variability and substantial intra-individual variability were estimated and could not be explained by any covariate. Higher plasma exposure to ibrutinib is associated with cessation of therapy due to the occurrence of adverse events within the first year of treatment. The association between disease progression and ibrutinib exposure in patients with mantle cell lymphoma should be further investigated. ClinicalTrials.gov no. NCT02824159.

Abstract: We recently identified the CDC25A phosphatase as a key actor in proliferation and differentiation in acute myeloid leukemia which expresses the FLT3-ITD mutation. In this paper we demonstrate that CDC25A level is controlled by a complex STAT5/miR-16 transcription and translation pathway working downstream of this receptor. First, we established by CHIP analysis that STAT5 is directly involved in FLT3-ITD-dependentCDC25Agene transcription. In addition, we determined that miR-16 expression is repressed by FLT3-ITD activity, and that STAT5 participates in this repression. In accordance with these results, miR-16 expression was significantly reduced in a panel of AML primary samples carrying the FLT3-ITD mutation when compared with FLT3wt cells. The expression of a miR-16 mimic reduced CDC25A protein and mRNA levels, and RNA interference-mediated down modulation of miR-16 restored CDC25A expression in response to FLT3-ITD inhibition. Finally, decreasing miR-16 expression partially restored the proliferation of cells treated with the FLT3 inhibitor AC220, while the expression of miR-16 mimic stopped this proliferation and induced monocytic differentiation of AML cells. In summary, we identified a FLT3-ITD/STAT5/miR-16/CDC25A axis essential for AML cell proliferation and differentiation.

Abstract: International audience; The prognostic value of IL7-receptor pathway (IL7Rp) mutations in T-cell acute lymphoblastic leukemia (T-ALL) remains unclear. We performed a comprehensive study of 200 adult patients with TALL included in the GRAALL2003/2005 protocols to address the clinical significance of IL7Rp mutations. Next-generation sequencing of the IL7Rp (IL7R/JAK1/ JAK3/STAT5B) revealed that IL7Rp mutations were frequent in adult TALL (28%) particularly in immature/early T-cell progenitor (ETP)-ALL. They were associated with mutations of NOTCH-pathway, PHF6, and PRC2 components but not with K/NRAS. IL7Rp mutated (IL7Rp mut) TALL were slow-responders, with a high rate of M2/M3 day-8 marrow compared with IL7Rp non-mutated (IL7Rp WT) TALL (p = 0.002) and minimal residual disease positivity at 6-weeks (MRD1) (p = 0.008) but no difference in MRD2 positivity at 12-weeks. Despite this, no adverse prognosis was evidenced when censored for allogeneic hematopoietic stem cell transplantation (HSCT). In time-dependent analysis, HSCT did not benefit IL7Rp mut patients whereas it was of marked benefit to IL7Rp WT cases. IL7Rp-mutations identify a subgroup of slow-responder T-ALLs which benefit from post-induction chemotherapy regimens but not from HSCT. Our data suggest that prior knowledge of the mutation status of IL7Rp may influence HSCT decision and help to guide therapy reduction.

Abstract: The oncogenic events involved in breast implant-associated anaplastic large cell lymphoma (BI-ALCL) remain elusive. To clarify this point, we have characterized the genomic landscape of 34 BI-ALCLs (15 tumor and 19 in situ subtypes) collected from 54 BI-ALCL patients diagnosed through the French Lymphopath network. Whole-exome sequencing (n = 22, with paired tumor/germline DNA) and/or targeted deep sequencing (n = 24) showed recurrent mutations of epigenetic modifiers in 74% of cases, involving notably KMT2C (26%), KMT2D (9%), CHD2 (15%), and CREBBP (15%). KMT2D and KMT2C mutations correlated with a loss of H3K4 mono- and trimethylation by immunohistochemistry. Twenty cases (59%) showed mutations in ≥1 member of the JAK/STAT pathway, including STAT3 (38%), JAK1 (18%), and STAT5B (3%), and in negative regulators, including SOCS3 (6%), SOCS1 (3%), and PTPN1 (3%). These mutations were more frequent in tumor-type samples than in situ samples (P = .038). All BI-ALCLs expressed pSTAT3, regardless of the mutational status of genes in the JAK/STAT pathway. Mutations in the EOMES gene (12%) involved in lymphocyte development, PI3K-AKT/mTOR (6%), and loss-of-function mutations in TP53 (12%) were also identified. Copy-number aberration (CNA) analysis identified recurrent alterations, including gains on chromosomes 2, 9p, 12p, and 21 and losses on 4q, 8p, 15, 16, and 20. Regions of CNA encompassed genes involved in the JAK/STAT pathway and epigenetic regulators. Our results show that the BI-ALCL genomic landscape is characterized by not only JAK/STAT activating mutations but also loss-of-function alterations of epigenetic modifiers.

Abstract: BackgroundThe epigenetic machinery is frequently altered in acute myeloid leukemia. Focusing on cytogenetically normal (CN) AML, we previously described an abnormal H3K27me3 enrichment covering 70 kb on theHIST1cluster (6.p22) in CN-AML patient blasts. Here, we further investigate the molecular, functional, and prognosis significance of this epigenetic alteration named H3K27me3HIST1inNPM1-mutated (NPM1mut) CN-AML.ResultsWe found that three quarter of theNPM1mut CN-AML patients were H3K27me3HIST1high. H3K27me3HIST1highgroup of patients was associated with a favorable outcome independently of known molecular risk factors. In gene expression profiling, the H3K27me3HIST1highmark was associated with lower expression of the histone genesHIST1H1D,HIST1H2BG,HIST1H2AE, andHIST1H3Fand an upregulation of genes involved in myelomonocytic differentiation. Mass spectrometry analyses confirmed that the linker histone protein H1d, but not the other histone H1 subtypes, was downregulated in the H3K27me3HIST1highgroup of patients. H1d knockdown primed ATRA-mediated differentiation of OCI-AML3 and U937 AML cell lines, as assessed on CD11b/CD11c markers, morphological and gene expression analyses.ConclusionsOur data suggest thatNPM1mut AML prognosis depends on the epigenetic silencing of theHIST1cluster and that, among the H3K27me3 silenced histone genes,HIST1H1Dplays a role in AML blast differentiation.Graphical abstract

Abstract: Background Evidences support social inequalities in cancer survival. Studies on hematological malignancies, and more specifically Acute Myeloid Leukemia (AML), are sparser. Our study assessed: 1/ the influence of patients’ socioeconomic position on survival, 2/ the role of treatment in this relationship, and 3/ the influence of patients’ socioeconomic position on treatment utilization. Methods This prospective multicenter study includes all patients aged 60 and older, newly diagnosed with AML, excluding promyelocytic subtypes, between 1st January 2009 to 31st December 2014 in the South-West of France. Data came from medical files. Patients’ socioeconomic position was measured by an ecological deprivation index, the European Deprivation Index. We studied first, patients’ socioeconomic position influence on overall survival (n = 592), second, on the use of intensive chemotherapy (n = 592), and third, on the use of low intensive treatment versus best supportive care among patients judged unfit for intensive chemotherapy (n = 405). Results We found an influence of patients’ socioeconomic position on survival (highest versus lowest position HRQ5: 1.39 [1.05;1.87] that was downsized to become no more significant after adjustment for AML ontogeny (HRQ5: 1.31[0.97;1.76] and cytogenetic prognosis HRQ5: 1.30[0.97;1.75]). The treatment was strongly associated with survival. A lower proportion of intensive chemotherapy was observed among patients with lowest socioeconomic position (ORQ5: 0.41[0.19;0.90]) which did not persist after adjustment for AML ontogeny (ORQ5: 0.59[0.25;1.40]). No such influence of patients’ socioeconomic position was found on the treatment allocation among patients judged unfit for intensive chemotherapy. Conclusions Finally, these results suggest an indirect influence of patients’ socioeconomic position on survival through AML initial presentation.

Abstract: International audience; BACKGROUND:Eradication of minimal residual disease (MRD), at the end of Fludarabine-Cyclophosphamide-Rituximab (FCR) treatment, is a validated surrogate marker for progression-free and overall survival in chronic lymphocytic leukaemia. But such deep responses are also associated with severe immuno-depletion, leading to infections and the development of secondary cancers.METHODS:We assessed, blood MRD and normal immune cell levels at the end of treatment, in 162 first-line FCR patients, and analysed survival and adverse event.RESULTS:Multivariate Landmark analysis 3 months after FCR completion identified unmutated IGHV status (HR, 2.03, p = 0.043), the level of MRD reached (intermediate versus low, HR, 2.43, p = 0.002; high versus low, HR, 4.56, p = 0.002) and CD4 > 200/mm3 (HR, 3.30, p

Abstract: High-dose chemotherapy before autologous transplantation is a therapeutic option as consolidation in primary or relapsed lymphoma. Even if BEAM conditioning is generally used, alternative conditioning regimens have been published. The purpose of this study was to assess the outcome of 177 adult patients with lymphoma whose conditioning treatment included a BAM (busulfan, aracytine, and melphalan) regimen. With a median follow-up of 17.4 months, 2-year estimates of overall survival and progression-free survival for the entire group were 87% and 70.5%, respectively. Mucositis was the main reported complications and infectious episodes were described in 80.2% of patients. According to multivariate analysis, high performance status and age at diagnosis were adverse factors for survival and increased the risk of disease relapse and death. Despite its limitations, this retrospective study suggests that BAM combination is a valid conditioning regimen in lymphoma patients, with an acceptable rate of toxicity.

Abstract: International audience; Background: Short intensive chemotherapy is the standard of care for adult patients with Burkitt's leukaemia or lymphoma. Findings from single-arm studies suggest that addition of rituximab to these regimens could improve patient outcomes. Our objective was to test this possibility in a randomised trial. Methods In this randomised, controlled, open-label, phase 3 trial, we recruited patients older than 18 years with untreated HIV-negative Burkitt's lymphoma (including Burkitt's leukaemia) from 45 haematological centres in France. Exclusion criteria were contraindications to any drug included in the chemotherapy regimens, any serious comorbidity, poor renal (creatinine concentration >150 μmol/L) or hepatic (cirrhosis or previous hepatitis B or C) function, pregnancy, and any history of cancer except for non-melanoma skin tumours or stage 0 (in situ) cervical carcinoma. Patients were stratified into two groups based on disease extension (absence [group B] or presence [group C] of bone marrow or central nervous system involvement). Patients were further stratified in group C according to age (60 years) and central nervous system involvement. Participants were randomly assigned in each group to either intravenous rituximab injections and chemotherapy (lymphome malin B [LMB]) or chemotherapy alone by the Groupe d'Etude des Lymphomes de l'Adulte datacentre. Randomisation was stratified by treatment group and centre using computer-assisted permuted-block randomisation (block size of four; allocation ratio 1:1). We gave rituximab (375 mg/m2) on day 1 and day 6 during the first two courses of chemotherapy (total of four infusions). The primary endpoint is 3 year event-free survival (EFS). We analysed all patients who had data available according to their originally assigned group. This trial is registered with ClinicalTrials.gov, number NCT00180882. Results Between Oct 14, 2004, and Sept 7, 2010, we randomly allocated 260 patients to rituximab or no rituximab (group B 124 patients [64 no rituximab; 60 rituximab]; group C 136 patients [66 no rituximab; 70 rituximab]). With a median follow-up of 38 months (IQR 24–59), patients in the rituximab group achieved better 3 year EFS (75% [95% CI 66–82]) than did those in the no rituximab group (62% [53–70]; log-rank p stratified by treatment group=0·024). The hazard ratio estimated with a Cox model stratified by treatment group, assuming proportionality, was 0·59 for EFS (95% CI 0·38–0·94; p=0·025). Adverse events did not differ between the two treatment groups. The most common adverse events were infectious (grade 3–4 in 137 [17%] treatment cycles in the rituximab group vs 115 [15%] in the no rituximab group) and haematological (mean duration of grade 4 neutropenia of 3·31 days per cycle [95% CI 3·01–3·61] vs 3·38 days per cycle [3·05–3·70]) events. Interpretation Addition of rituximab to a short intensive chemotherapy programme improves EFS in adults with Burkitt's leukaemia or lymphoma.

Abstract: Dendrogenin A (DDA), a mammalian cholesterol metabolite with tumor suppressor properties, has recently been shown to exhibit strong anti-leukemic activity in acute myeloid leukemia (AML) cells by triggering lethal autophagy. Here, we demonstrated that DDA synergistically enhanced the toxicity of anthracyclines in AML cells but not in normal hematopoietic cells. Combination index of DDA treatment with either daunorubicin or idarubicin indicated a strong synergism in KG1a, KG1 and MV4-11 cell lines. This was confirmed in vivo using immunodeficient mice engrafted with MOLM-14 cells as well as in a panel of 20 genetically diverse AML patient samples. This effect was dependent on Liver X Receptor &beta, a major target of DDA. Furthermore, DDA plus idarubicin strongly increased p53BP1 expression and the number of DNA strand breaks in alkaline comet assays as compared to idarubicin alone, whereas DDA alone was non-genotoxic. Mechanistically, DDA induced JNK phosphorylation and the inhibition of AKT phosphorylation, thereby maximizing DNA damage induced by idarubicin and decreasing DNA repair. This activated autophagic cell death machinery in AML cells. Overall, this study shows that the combination of DDA and idarubicin is highly promising and supports clinical trials of dendrogenin A in AML patients.

Abstract: International audience; Replacement therapy with plasma-derived or recombinant FIX (pdFIX or rFIX) concentrates is the standard of treatment in patients with hemophilia B. The method predominantly used for measuring factor IX (FIX:C) levels is the one-stage clotting assay (OSA) but this method depends on the activated partial thromboplastin time (APTT) reagent and the coagulation analyzer used, and wide variations in the measurements of FIX recovery have been reported with some factor concentrates. The French study group on the biology of hemorrhagic diseases (a collaborative group of the GFHT and MHEMO network), presents a review of the literature and proposals for the monitoring of FIX:C levels in treated hemophilia B patients. The use of OSA calibrated with a plasma reference tested against the current FIX WHO International Standard is recommended for the monitoring of patients treated with pdFIX or rFIX. Chromogenic substrate assays (CSA) are adequate for the monitoring of patients treated with Rixubis®, but data available for Benefix® are currently too limited. For extended half-life rFIX (EHL-rFIX), large discordances in the FIX:C levels measured were evidenced, depending on the method and reagents used. Great attention is therefore required for measuring FIX:C levels by OSA in patients substituted by EHL-rFIX. Commercial kits for CSA are not equivalent, and although potentially useful, they are not validated for all EHL-rFIX. Most of recent studies reported data obtained with spiked plasmas, which deserve to be confirmed on plasma samples collected in treated patients.

Abstract: This study was initiated to evaluate an iterative reconstruction algorithm in positron emission tomography based on a regularization method to obtain convergence. Our aim was to assess its performance, in comparison with other currently available algorithms and to study the impact of the only parameter available to users for eventual optimization, both using anthropomorphic phantoms and clinical data. We confirm that this algorithm shows several advantages compared to the traditional OSEM-MLEM concerning noise, contrast and detectability. By using anthropomorphic phantoms and with access to more reconstruction parameters, the performance could be further improved to decrease the artefacts and the overestimation of certain metrics. Work in progress., L'étude a été initiée à l'occasion de la disponibilité d'un algorithme itératif de reconstruction en tomographie par émission de positons, qui présente l'avantage d'atteindre la convergence grâce à une méthode de régularisation. Il a donc fallu évaluer ses performances et son éventuel apport en comparaison aux algorithmes de référence, puis étudier l'influence du seul paramètre accessible aux utilisateurs pour une optimisation en clinique. Pour cela, plusieurs tests ont été réalisés, sur fantômes d'abord, puis sur patients car les résultats obtenus n'étaient pas directement transposables en clinique. Cet algorithme a de nombreux avantages par rapport au standard actuel OSEM-MLEM (moins de bruit, meilleur contraste, meilleure détectabilité des lésions) mais pourrait encore être amélioré pour diminuer les artéfacts et la surestimation de certaines métriques, grâce à l'utilisation de fantômes plus anthropomorphiques et l'accès à plus de paramètres de reconstruction. Des travaux sont encore en cours avec l'éditeur.

Abstract: F-18-fluorodeoxyglucose positron emission tomography integrated with computed tomography (FDG-PET/CT) is actually considered as the standard technique to assess and monitor the metabolic response to therapy and to define minimal residual disease (MRD) status outside the bone marrow (BM) in multiple myeloma (MM) patients. In this regard, standardization of image criteria and definition of cut-offs for positivity/negativity is of highly importance. Aim of the present study was to prospectively evaluate FDG-PET/CT at diagnosis and prior to maintenance therapy in a joined analysis of a sub-group of patients with newly diagnosed transplant-eligible MM, enrolled in 2 independent European randomized phase III trials (EMN02/HO95 and IFM2009) (Cavo M et al, Blood 2017 abs; Attal M et al, NEJM 2017). The primary end-point was to standardize PET/CT evaluation by centralized imaging and revision and to define criteria for PET negativity after therapy (MRD definition). 236 patients (102 and 134 from the EMN02 and IFM2009 trial, respectively) were enrolled in the PET/CT imaging sub-studies and followed for a median of 62.9 (IQR: 44.9-67.9) months. By study design, PET/CT scans were performed locally at baseline (B) and prior to the start of maintenance (PM), uploaded in a central website and re-interpreted a-posteriori in a blinded independent central review process, by a panel of expert nuclear medicine physicians. According to the IMPeTUs criteria (Nanni C et al, EJNM 2017), the five-point Deauville scores (between 1 and 5) were applied to the following parameters: bone marrow (BM), focal lesions (FLs), extramedullary disease (EMD). The impact of each parameter on outcomes was evaluated by landmark analyses at PM; the univariate and multivariate analyses were stratified by trial to smooth out differences between the 2 studies. Baseline characteristics of the patients were generally homogeneous between the 2 trials and as follows: median age 59 years, ISS and R-ISS stage III 15.8% and 11.5%, respectively, high-risk cytogenetics (t(4;14) ± del(17p) ± t(14;16) detected by FISH) 14%. Fifty seven percent of the patients were randomized in the transplant arm, and 43% in the bortezomib-intensification arm, with a higher percentage in the IFM2009 vs EMN02 trial (54% vs 24%, respectively). At baseline, 80% of the patients had FLs, with a median maximum standardized uptake value (SUVmax) of 5. Median BM SUVmax was 3. Both median FLs and BM SUVmax were slightly higher in the IFM2009 vs the EMN02 trial (5.7 vs 4.2 and 3.7 vs 2.68, respectively), while reference SUVmean (mediastinal blood pool and liver) did not differ between the 2 studies. FLs Deauville score (FS) and BM Deauville score (BMS) > 3 (higher than the liver) were present in 79.8% and 35.5% of the patients, respectively, with no difference between the 2 trials. EMD was present in 11% of the patients. Prior to maintenance therapy, median FLs and BM SUVmax were 3.6 and 2.3, respectively, with 53.5% and 71.2% of the patients obtaining a FS and BMS ≤ 2 and 79% and 91.4% ≤ 3, respectively. In univariate analysis, at Landmark time prior to maintenance, attaining a FS and BMS ≤ 3 was the strongest predictor for prolonged PFS (FS≤ 3 vs >3: median 40 vs 26.6 months, HR 0.6, CI 0.39-0.98, P= 0.0019; BMS≤ 3 vs >3: median 39.8 vs 26.6 months, HR 0.47, CI 0.24-0.91, P= 0.024, respectively) and OS (FS≤ 3 vs >3: estimate at 63 months 73% vs 63.6% months, HR 0.51, CI 0.26-0.98, P= 0.028; BMS≤ 3 vs >3: estimate at 75.5% vs 49.7%, HR 0.28, CI 0.12-0.64, P= 0.002, respectively) and could be identified as the most representative cut-off values for PET negativity after therapy. Of the two PM scores, only FS ≤ 3 retained prognostic relevance in the subgroup of patients not receiving transplant, in terms of PFS. In Cox multivariable analysis, FS and BMS ≤ 3 at PM were independent predictors of prolonged PFS (FS: HR 0.58, CI 0.35-0.96, P= 0.036; BMS HR 0.41, CI 0.20-0.84, P= 0.014) and OS (FS: HR 0.36, CI 0.17-0.74, P= 0.005; BMS HR 0.24, CI 0.09-0.63, P= 0.004). In conclusion, FDG PET/CT was confirmed to be a reliable predictor of outcomes in newly diagnosed MM, regardless of treatment. Reduction of FDG uptake lower than the liver after therapy, both in the FLs and in the BM (FS and BMS), was an independent predictor for improved PFS and OS. Findings from this analysis could be proposed as standardized criteria to define PET negativity after therapy, confirming the value of Deauville scores in MM.

Abstract: Background: Nivolumab demonstrated remarkable activity in patients with relapse or refractory (R/R) Hodgkin lymphoma (HL). However, long term efficacy and the need for a consolidation with allogenic stem cell transplantation remain unclear. Patient and method: We retrospectively analyzed 78 patients with R/R HL treated with nivolumab in the French Early Access Program and compared their outcome according to subsequent alloHSCT. Results: After a median follow-up of 31.5 months, the best overall response rate was 64%, including 37.3% complete response (CR). The median progression-free survival (PFS) was 12.1 months and median overall survival (OS) was not reached. At 3 years, PFS and OS rates were 35% and 65%, respectively. Patients reaching a CR upon nivolumab had a significantly longer PFS than those reaching a PR (median = not reached vs 10.1 months). In our cohort, 17 patients underwent consolidation with allogenic stem cells transplantation (alloHSCT) after nivolumab therapy (Figure 1). At the time of transplantation, 8 patients were in CR, 5 in partial response (PR) and 4 had progressed of whom 3 received a salvage therapy before alloHSCT. Interestingly, 6 out of 7 patients who were not in CR at the time of transplantation (5 PR and 1 progressive disease) converted into a CR after alloHSCT. At the time of analysis, 14 patients were alive and 13 remained disease-free after a median follow-up of 30.4 months. One-year OS and PFS from alloHSCT were 82% and 76%, respectively. Among responding patients (i.e. in CR or PR) after nivolumab monotherapy, those who underwent subsequent alloHSCT (N=13) had a better outcome than those who were not consolidated with alloHSCT (N=35) (Figure 2). In the transplanted group, none of the patients relapsed whereas in the non-transplanted group 60% of the patients relapsed (p Conclusions: Although patients who achieve a CR upon anti-PD1 therapy may experience prolonged remissions, most R/R HL patients treated with anti-PD1 antibody eventually progress or relapse. Our study demonstrates unprecedented disease-free survival in patients undergoing consolidation with alloHSCT after anti-PD1 therapy. Interestingly, alloHSCT post anti-PD1 can convert incomplete responses into CR in most cases. Despite expected toxicities, alloHSCT after anti-PD1 therapy appears manageable and safe in most patients. Our results suggest that consolidation with alloHSCT may represent a good option in patients treated with anti-PD1, notably in patients who are unable to achieve a CR.

Abstract: Purpose: To assess the prognostic value of interim 18F-fluorodeoxyglucose (FDG)-PET analysis using decrease in maximum standardized uptake value (SUVmax) versus visual analysis in patients with multiple myeloma. Patients and Methods: We evaluated the prognostic value of FDG-PET after three cycles of lenalidomide, bortezomib, and dexamethasone (RVD) in patients with FDG-avid multiple myeloma included in the French prospective multicenter IMAJEM study. All images were centrally reviewed and interpreted using visual criteria and maximal standardized uptake value reduction (ΔSUVmax). Known prognostic factors, such as the revised International Staging System and biochemical response after three cycles of chemotherapy, were also evaluated. Results: In the multivariate analysis, only ΔSUVmax [P < 0.001, HR = 5.56; 95% confidence interval (CI), 1.96–15.81] and biochemical response after three cycles of RVD (P = 0.025, HR = 0.29; 95% CI, 0.1–0.85) appeared as independent prognostic factors, with a more discriminative HR for ΔSUVmax. ΔSUVmax analysis (>–25% vs. ≤–25%) identified patients with improved median progression-free survival (22.6 months and not reached, respectively). Conclusions: ΔSUVmax appears to be a powerful tool for the prediction of long-term outcome in patients with FDG-avid multiple myeloma. Other prospective studies are needed to further validate this prognostic biomarker. Clin Cancer Res; 24(21); 5219–24. ©2018 AACR.

Abstract: Purpose Acute myeloid leukemia (AML) in elderly patients has a poor prognosis. In an attempt to improve outcome for these patients, the prospective open-label phase III LAM-SA 2007 (Adding Lomustine to Chemotherapy in Older Patients With Acute Myelogenous Leukemia (AML), and Allogeneic Transplantation for Patients From 60 to 65 Years Old) trial randomly assigned patients to a standard induction regimen with lomustine added or to a consolidation regimen with cytarabine and idarubicin. Patients and Methods Adults age 60 years or older with previously untreated AML who were fit to receive intensive chemotherapy and who were without unfavorable cytogenetics received standard chemotherapy with lomustine (idarubicin, cytarabine, and lomustine [ICL]) or without (idarubicin and cytarabine [IC]). The primary objective of the study was overall survival (OS); secondary objectives were response rate, cumulative incidence of relapse (CIR), event-free survival (EFS), and safety. Results From February 2008 to December 2011, 459 patients were enrolled. Comparing patients in the IC and ICL arms, complete response or complete response with incomplete recovery was achieved in 74.9% versus 84.7% ( P = .01). The proportional hazards assumption was rejected for OS ( P = .02), which led us to consider two separate time intervals: during and after induction. There was no significant difference between the two arms during induction, although induction deaths were 3.7% versus 7.7%, respectively ( P = .11). However, significantly better results were observed after induction with an improved 2-year OS of 56% in the ICL arm versus 48% in the IC arm ( P = .02). At 2 years, EFS was improved at 41% in the ICL arm versus 26% in the IC arm ( P = .01). The CIR at 2 years was 41.2% in the ICL arm versus 60.9% in the IC arm ( P = .003). Grade 3 and 4 toxicities, mostly hematologic, were significantly higher in the ICL arm ( P = .04), and fewer patients required a second treatment after ICL. Conclusion Adding lomustine to standard chemotherapy significantly improved the outcome of elderly patients with AML.

Abstract: International audience; Essentials Risk factors of bleeding in adult immune thrombocytopenia are not known. This multicenter study assessed risk factors of bleeding at immune thrombocytopenia onset. Platelet count thresholds associated with bleeding were < 20 × 109 L-1 and < 10 × 109 L-1 . Exposure to anticoagulants was a major risk factor of severe bleeding.Summary: Background The aim of this cross-sectional study was to assess risk factors for bleeding in immune thrombocytopenia (ITP) adults, including the determination of platelet count thresholds. Methods We selected all newly diagnosed ITP adults included in the Cytopénies Auto-immunes Registre Midi-PyrénéEN (CARMEN) register and at the French referral center for autoimmune cytopenias. The frequencies of any bleeding, mucosal bleeding and severe bleeding (gastrointestinal, intracranial, or macroscopic hematuria) at ITP onset were assessed. Platelet count thresholds were assessed by the use of receiver operating characteristic curves. All potential risk factors were included in logistic regression models. Results Among the 302 patients, the frequencies of any, mucosal and severe bleeding were 57.9%, 30.1%, and 6.6%, respectively. The best discriminant threshold of platelet count for any bleeding was 20 × 109 L-1 . In multivariate analysis, factors associated with any bleeding were platelet count (< 10 × 109 L-1 versus ≥ 20 × 109 L-1 , odds ratio [OR] 48.2, 95% confidence interval [CI] 20.0-116.3; between 10 × 109 L-1 and 19 × 109 L-1 versus ≥ 20 × 109 L-1 , OR 5.2, 95% CI 2.3-11.6), female sex (OR 2.6, 95% CI 1.3-5.0), and exposure to non-steroidal anti-inflammatory drugs (NSAIDs) (OR 4.8, 95% CI 1.1-20.7). A low platelet count was also the main risk factor for mucosal bleeding. Exposure to anticoagulant drugs was associated with severe bleeding (OR 4.3, 95% CI 1.3-14.1). Conclusions Platelet counts of < 20 × 109 L-1 and < 10 × 109 L-1 were thresholds for major increased risks of any and mucosal bleeding. Platelet count, female sex and exposure to NSAIDs should be considered for assessment of the risk of any bleeding. Exposure to anticoagulant drugs was a major risk factor for severe bleeding.

Abstract: International audience; Alteration in the DNA replication, repair or recombination processes is a highly relevant mechanism of genomic instability. Despite genomic aberrations manifested in hematologic malignancies, such a defect as a source of biomarkers has been underexplored. Here, we investigated the prognostic value of expression of 82 genes involved in DNA replication-repair-recombination in a series of 99 patients with chronic lymphocytic leukemia without detectable 17p deletion or TP53 mutation. We found that expression of the POLN gene, encoding the specialized DNA polymerase ν (Pol ν) correlates with time to relapse after first-line therapy with fludarabine. Moreover, we found that POLN was the only gene up-regulated in primary patients’ lymphocytes when exposed in vitro to proliferative and pro-survival stimuli. By using two cell lines that were sequentially established from the same patient during the course of the disease and Pol ν knockout mouse embryonic fibroblasts, we reveal that high relative POLN expression is important for DNA synthesis and cell survival upon fludarabine treatment. These findings suggest that Pol ν could influence therapeutic resistance in chronic lymphocytic leukemia. (Patients’ samples were obtained from the CLL 2007 FMP clinical trial registered at: clinicaltrials.gov identifer: 00564512).

Abstract: Boutzen et al. show that the IDH1 mutation and its oncometabolite, (R)-2-hydroxyglutarate, dysregulate downstream target pathways of myeloid-specific TFs, especially CEBPα, priming mutant IDH1-R132H AML blasts to the granulomonocytic lineage., Acute myeloid leukemia (AML) is characterized by the accumulation of malignant blasts with impaired differentiation programs caused by recurrent mutations, such as the isocitrate dehydrogenase (IDH) mutations found in 15% of AML patients. These mutations result in the production of the oncometabolite (R)-2-hydroxyglutarate (2-HG), leading to a hypermethylation phenotype that dysregulates hematopoietic differentiation. In this study, we identified mutant R132H IDH1-specific gene signatures regulated by key transcription factors, particularly CEBPα, involved in myeloid differentiation and retinoid responsiveness. We show that treatment with all-trans retinoic acid (ATRA) at clinically achievable doses markedly enhanced terminal granulocytic differentiation in AML cell lines, primary patient samples, and a xenograft mouse model carrying mutant IDH1. Moreover, treatment with a cell-permeable form of 2-HG sensitized wild-type IDH1 AML cells to ATRA-induced myeloid differentiation, whereas inhibition of 2-HG production significantly reduced ATRA effects in mutant IDH1 cells. ATRA treatment specifically decreased cell viability and induced apoptosis of mutant IDH1 blasts in vitro. ATRA also reduced tumor burden of mutant IDH1 AML cells xenografted in NOD–Scid–IL2rγnull mice and markedly increased overall survival, revealing a potent antileukemic effect of ATRA in the presence of IDH1 mutation. This therapeutic strategy holds promise for this AML patient subgroup in future clinical studies.

Abstract: Patients with acute myeloid leukemia (AML) in relapse or refractory to induction therapy have a dismal prognosis. Allogeneic hematopoietic stem cell transplantation is the only curative option. In these patients, we aimed to compare the results of a myeloablative transplant versus a sequential approach consisting in a cytoreductive chemotherapy followed by a reduced intensity conditioning regimen and prophylactic donor lymphocytes infusions. We retrospectively analyzed 99 patients aged 18-50 years, transplanted for a refractory (52%) or a relapsed AML not in remission (48%). Fifty-eight patients received a sequential approach and 41 patients a myeloablative conditioning regimen. Only 6 patients received prophylactic donor lymphocytes infusions. With a median follow-up of 48 months, 2-year overall survival was 39%, 95% confidence interval (CI) (24-53) in the myeloablative group versus 33%, 95% CI (21-45) in the sequential groups (P = .39), and 2-year cumulative incidence of relapse (CIR) was 57% versus 50% respectively (P = .99). Nonrelapse mortality was not higher in the myeloablative group (17% versus 15%, P = .44). In multivariate analysis, overall survival, CIR and nonrelapse mortality remained similar between the two groups. However, in multivariate analysis, sequential conditioning led to fewer acute grade II-IV graft versus host disease (GVHD) (HR for sequential approach = 0.37; 95% CI: 0.21-0.65; P < .001) without a significant impact on chronic GVHD (all grades and extensive). In young patients with refractory or relapsed AML, myeloablative transplant and sequential approach offer similar outcomes except for a lower incidence of acute GvHD after a sequential transplant.

Abstract: International audience; Alteration in the DNA Replication, Repair or Recombination processes is a highly relevant mechanism of genomic instability. Despite genomic aberrations manifested in haematological malignancies, such a defect as a source of biomarkers has been underexplored. Here, we investigated prognostic value of expression of 82 genes involved in DNA Replication-Repair-Recombination in a series of 99 patients with chronic lymphocytic leukaemia without detected 17p deletion or TP53 mutation. We unveiled that expression of the POLN gene, encoding the specialized DNA polymerase ν (Polν) correlates with time to relapse after the first-line therapy with fludarabine. Moreover, we found that POLN was the only gene upregulated in primary patient lymphocytes when exposed in vitro to proliferative and prosurvival stimuli. By using 2 cell lines that were sequentially established from the same patient during the course of the disease and Polν knockout mouse embryonic fibroblasts, we reveal that relative high POLN expression is important for DNA synthesis and cell survival upon fludarabine treatment. These findings suggest that Polν could influence therapeutic resistance in chronic lymphocytic leukemia.

Abstract: International audience; Multiple myeloma (MM) is a proliferation of tumoral plasma B cells that is still incurable. Natural killer (NK) cells can recognize and kill MM cells in vitro and can limit MM growth in vivo. Previous reports have shown that NK cell function is impaired during MM progression and suggested that treatment with immunomodulatory drugs (IMIDs) such as lenalidomide (LEN) could enhance it. However, the effects of IMIDs on NK cells have been tested mostly in vitro or in preclinical models and supporting evidence of their effect in vivo in patients is lacking. Here, we monitored NK cell activity in blood samples from 10 MM patients starting after frontline induction chemotherapy (CTX) consisting either of association of bortezomib-lenalidomide-dexamethasone (Velcade Revlimid Dexamethasone) or autologous stem-cell transplantation (SCT). We also monitored NK cell activity longitudinally each month during 1 year, after maintenance therapy with LEN. Following frontline chemotherapy, peripheral NK cells displayed a very immature phenotype and retained poor reactivity toward target cells ex vivo. Upon maintenance treatment with LEN, we observed a progressive normalization of NK cell maturation, likely caused by discontinuation of chemotherapy. However, LEN treatment neither activated NK cells nor improved their capacity to degranulate or to secrete IFN-γ or MIP1-β following stimulation with MHC-I-deficient or antibody-coated target cells. Upon LEN discontinuation, there was no reduction of NK cell effector function either. These results caution against the use of LEN as single therapy to improve NK cell activity in patients with cancer and call for more preclinical assessments of the potential of IMIDs in NK cell activation.

Abstract: International audience; PURPOSE:Eribulin is approved for advanced breast cancers refractory to anthracyclines and taxanes. Efficacy according to sensitivity to previous therapies has been poorly explored.MATERIALS AND METHODS:Safety data were collected prospectively and we retrospectively collected efficacy data from the five French centres that participated in the Eribulin E7389-G000-398 expanded access program. Our main objectiveswere exploration of safety and analysis of eribulin efficacy (progression-free survival [PFS] and overall survival [OS]) according to sensitivity to the last microtubule-inhibiting agent administered.RESULTS:Median eribulin treatment duration was 3.3 months for the 250 patients included in this prospective single-arm study. Two hundreds and thirty-nine patients (95.6%) experienced an adverse event (AE) related to treatment including 129 (51.6%) with grade ≥ 3 AEs. The most frequently observed toxicities were cytopenias (59.6% of included patients), gastrointestinal disorders (59.2%), and asthenia (56.4%). The most frequent grade 3-4 AE was neutropenia (37.2% with 4.8% febrile neutropenia). Median PFS and OS were 4.6 and 11.8 months, respectively. Patients classified as responders to the last microtubule-inhibiting therapy had a longer OS (hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.51 to 0.94; p=0.017), and tended to display a better PFS (HR, 0.78; 95% CI, 0.58 to 1.04; p=0.086). OS improvement was still significant in multivariate analysis (adjusted HR, 0.53; 95% CI, 0.35 to 0.79; p=0.002).CONCLUSION:This work based on a prospective study suggests that identification of patients likely to be more sensitive to eribulin could be based on their previous response to microtubules inhibitors.
