Abstract: 8029 Background: Hodgkin Lymphoma (HL) treatment in the elderly is a challenge, as standard ABVD is able to cure no more than 60% of the patients (p.). Bendamustine (Be), and Brentuximab Vedotin (BV), are well-tolerated and effective drugs in relapsing HL, but only preliminary data exist in 1st line treatment of the elderly (Evens AM 2018). Methods: HALO is a prospective international multicenter open-label phase I/II study (NCT02467946) to assess the safety and efficacy of Be-BV in advanced-stage elderly HL p. Briefly, BV 1.2 mg/kg on D1, and Be 90 mg/m2 on D1-2 were administered Q3W for 6 cycles. The primary endpoint was the feasibility and the efficacy of Be-BV. Results: Between July 2015 and February 2019, 59/60 p. consecutive enrolled received at least 1 Be-BV cycle, and are valuable for primary endpoint. One p. was excluded because a histological review showing angioimmunoblastic T-Cell Lymphoma. The mean age was 70.32 (62-79), and M/F ratio 41/18. The Ann-Arbor stage was IIB in 12, III in 14 and IV in 33 patients, B-symptoms (y/n) 40/19. IPS was 0-2 in 19 and ≥ 3 in 40 p., P.S. (ECOG) was 0-1 in 53, 2 in 6 p., nonetheless most of them were frail, as ADL was ≥ 6 in 47 (79%) and IADL was ≥ 8 in 42 (71%) p. Most frequent co-morbidities were cardio-vascular disease (45) metabolism disorders (31) prostatic adenoma (11). 163 treatment-related adverse events (WHO 3-4) were recorded: neutropenia and lymphopenia, (134), infections (7), cutaneous reactions (5), liver toxicity (2). No case of grade 〉 2 peripheral neuropathy was recorded. Out of 59 p., 41 concluded and 18 interrupted the treatment for toxicity (8), progression (5), treatment failure (2), CMV reactivation (3). The latter was recorded in 17 p., 12/17 received valgancyclovir. 4 p. died with CMV viremia. After a mean follow-up of 20.6 (0.3-46.5) months, 37/59 (63%) were in CR, while 22 (37%) have progressed (5) or relapsed (17). The 2-y OS and PFS in ITT analysis were 83% (95% CI 71-96) and 54% (95% CI 41-72) and in PP 89% (95%CI 75-100) and 78% (95%CI 64-96), respectively. 22 p. had a PFS event: 5 progression (2 deaths), 17 relapse (8 deaths). 10 p. died for recurrent HL (5), sepsis (1), secondary malignancy (2), respiratory insufficiency (1) and unknown (1). Conclusions: The Be-BV combination, a novel anthracycline-free regiment for first line treatment of HL in elderly, proved effective in unselected, frail, poor-risk, HL p. aged more than 60 in daily hospital real life. The CMV reactivation is frequent and should be treated with preemptive antiviral therapy upon detection of CMV DNA in plasma. Clinical trial information: NCT02467946 .

Abstract: Background Ixazomib (IXA) is an orally-administered proteasome inhibitor approved in Europe in November 2016 for relapsed and/or refractory multiple myeloma (RRMM). It became available in France in May 2017 via a compassionate use program (CUP) and from October 2018 via the classical market access (non-CUP). In addition to pivotal clinical trials, real-world evidence (RWE) is required to evaluate effectiveness and safety in clinical routine practices. A non-interventional study, has been conducting in France to evaluate IXA use in combination with lenalidomide and dexamethasone (IRD) in real life. Methods REMIX is a non-interventional, multicentric study to assess IRD effectiveness and safety, conducted in 59 sites (public and private) in patients with RRMM. IRD was initiated in second line or more during the CUP and afterwards. After inclusion, patients were assessed every 3 months (mo) during 24 mo then every 6 mo as per standard practice. This interim analysis assessed IRD effectiveness (median Progression Free Survival (mPFS), 12 and 24-mo overall survival (OS) rates and tolerance in the CUP patients initiating IXA concomitantly to RD (patients who started lenalidomide more than 6 weeks before IXA were excluded). The analysis was conducted globally and per subgroups (age, number of lines of treatment, frailty as defined by Facon T & al.in Leukemia 2020). The CUP-patient median study follow-up was 17.4 mo for this interim analysis. Results The 198 eligible CUP patients were 47% of males, with a median age of 69 years (26% ≥75y). Out of them, 45% were frail and 7% had renal failure (CrCl ≤30 ml/min). Comorbidities were reported in 64% of patients including diabetes (9%), renal disease (10%), solid tumor (9%). At diagnosis, the cytogenetic risk was standard, high or unknown in respectively 46%, 13% and 41% of patients; 11% presented a plasmacytoma. 41% had multiple or severe bone lesions and 25% peripheral neuropathy. MM was diagnosed at a median of 4 years before IRD initiation. IXA was initiated after one (L2) / two (L3) / three or more lines of treatment (L4+) in respectively 58%, 18% and 24% of patients. Of them, 38% had received lenalidomide during prior line(s), mainly in patients with L3 and L4+ (78%, 65/84) vs L2 (8%, 9/114). The median washout period between lenalidomide discontinuation and IRD start was 18 mo 95%CI [17.6 - 29.6]. The mPFS was 19.2 mo 95%CI [13.3; 21.9] for the CUP cohort. mPFS was 21.5 mo 95%CI [13.3; 21.9] for L2 (104 patients), 17,8 mo 95%CI [12.2; 26.7] for L3 (29 patients) and 5.6 mo 95%CI [4.1; 8.8] for L4+ (38 patients) (c.f. Figure1). mPFS was similar in & lt;75 YO (19.2, mo 95%CI [12.3; 24.8]) and in ≥75 YO patients (19.2 mo, 95%CI [1.7; 21.5] ). In the subgroup with available frailty score (n= 124), mPFS was 21.5 mo 95%CI [12.5; -] in non-frail and 13.3 mo 95%CI [5.6 ; 19.8] ) in frail patients. 12mo and 24mo-OS rates were 84% 95%CI [78%; 89%] and 73% 95%CI [65%; 80%] for the global group. Among the 166 patients with available response according to investigators, overall response rate (ORR) was 68% (66% in & lt;75 YO and 71% in ≥75 YO patients) and very good partial response (VGPR) 35% (38% in & lt;75 YO and 27% in ≥75 YO patients). The 187 followed-up CUP patients received a median of 14 IRD cycles. IXA discontinuation was reported in 50% of patients (n=92), related to AE in 13% of cases (n= 24). Serious adverse events were reported in 34% (n=69), including 14 (7%) patients with SAE considered related to IXA. Most frequent ( & gt;10%) AE were thrombocytopenia (30%), diarrhoea (28%), asthenia (20%), anaemia (18%), neutropenia (15%), nausea (14%) and peripheral neuropathy (10%). Conclusion Few RWE data have been published for IXA use in Europe. In this first interim analysis, estimated mPFS is consistent with MM1 results or data reported in MM1 study (19,2 mo vs 20.6 mo) even though CUP patients in REMIX were globally elder, frailer and more frequently treated in advanced lines (24% of L4+ in REMIX vs 11% of L4 in MM1). Reported adverse events were in line with known safety IXA profile.

Abstract: Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a rare aggressive T-cell lymphoma most reported in Asia. We performed a comprehensive clinical, pathological and genomic study of 71 European MEITL patients (36 males, 35 females, median age 67 years). The majority presented with gastrointestinal involvement and had emergency surgery, and 40% had stage IV disease. The tumors were morphologically classified into two groups: typical (58%) and atypical (i.e., non-monomorphic or with necrosis, angiotropism or starry-sky pattern) (42%), sharing a homogeneous immunophenotypic profile (CD3+ [98%] CD4- [94%] CD5- [97%] CD7+ [97%] CD8+ [90%] CD56+ [86%] CD103+ [80%] cytotoxic marker+ [98%] ) with more frequent expression of TCRgd (50%) than TCRab (32%). MYC expression (30% of cases) partly reflecting MYC gene locus alterations, correlated with non-monomorphic cytology. Almost all cases (97%) harbored deleterious mutation(s) and/or deletion of the SETD2 gene and 90% had defective H3K36 trimethylation. Other frequently mutated genes were STAT5B (57%), JAK3 (50%), TP53 (35%), JAK1 (12.5%), BCOR and ATM (11%). Both TP53 mutations and MYC expression correlated with atypical morphology. The median overall survival (OS) of 63 patients (43/63 only received chemotherapy after initial surgery) was 7.8 months. Multivariate analysis found a strong negative impact on outcome of MYC expression, TP53 mutation, STAT5B mutation and poor performance status while aberrant B-cell marker expression (20% of cases) correlated with better survival. In conclusion, MEITL is an aggressive disease with resistance to conventional therapy, predominantly characterized by driver gene alterations deregulating histone methylation and JAK/STAT signaling and encompasses genetic and morphologic variants associated with very high clinical risk.

Abstract: In the rituximab era, one‐third of diffuse large B‐cell lymphoma patients experience relapse/refractory disease after first‐line anthracycline‐based immunochemotherapy. Optimal management remains an unmet medical need. The aim of this study was to report the outcomes of a cohort of refractory patients according to their patterns of refractoriness and the type of salvage option. We performed a retrospective analysis, which included 104 diffuse large B‐cell lymphoma patients treated at Lyon Sud University Hospital (2002‐2017) who presented with refractory disease. Refractoriness was defined as progressive/stable disease during first‐line treatment (primary refractory, N  = 47), a partial response after the end of first‐line treatment that required subsequent treatment (residual disease, N  = 19), or relapse within 1 year of diagnosis after an initial complete response (CR) (early relapse, N  = 38). The 2‐year overall survival (OS) rates for primary refractory, early relapse, and residual disease patients were 27%, 25%, and 52%, respectively, while the event‐free survival rates for those groups were 13%, 13%, and 42%, respectively. In a univariate analysis, lactate dehydrogenase level, Ann Arbor stage, poor performance status, high age‐adjusted International Prognostic Index score, and age  〉  65 years were associated with shorter OS. The use of rituximab and platinum‐based chemo during the first salvage treatment was associated with prolonged OS. In a multivariate analysis, age (HR:2.06) and rituximab use (HR:0.54) were associated with OS. Among patients 〈 65 years who achieved a CR, autologous stem‐cell transplant was associated with higher 2‐year OS (90% vs 74%, P  = 0.10). Patients who were treated with a targeted therapy in the context of a clinical trial after second‐line treatment had a higher 2‐year OS (34% vs 19%, P  = 0.06). In conclusion, patients with primary refractory disease or early relapse have very poor outcomes but may benefit from rituximab retreatment during the first salvage treatment.

Abstract: Obesity has been associated with an increased risk of developing acute myeloblastic leukaemia (AML). The outcome of AML patients could thus be dependent on their nutritional status that can be evaluated by the simple measurement of serum albumin (SA) and body mass index (BMI). These two parameters could have a value as prognostic factors to guide patients' management. We evaluated the association between SA levels, BMI, and survival, evaluated as overall survival (OS) and event‐free survival. Furthermore, we investigated the association between BMI, SA, and other prognostic factors of interest in AML. This retrospective single‐center study included 159 patients diagnosed with AML at Nancy Hospital between 2005 and 2013, treated with aracytine and anthracycline. Forty‐four percent of patients presented with normal weight while 56% were obese/overweight. Serum albumin levels were 〈 30 g/L for 49 patients, and ≥30 g/L for 110. Thirty‐four patients with low SA levels were also obese. Favourable OS was associated with SA levels ≥30 g/L (HR = 0.467; 95% CI 0.230‐0.946; P  = .034) but was not impacted by the BMI. Serum albumin levels appear to be an independent prognostic factor in AML and a better parameter than BMI for evaluating the nutritional status of patients at diagnosis.

Abstract: Background : AETHERA randomized controlled study (Moskowitz, Lancet 2015) showed that the administration of Brentuximab Vedotin (BV) maintenance after autologous stem cell transplantation (ASCT) improved progression free survival (PFS) in BV-naive refractory/relapsed (R/R) Hodgkin lymphoma (HL) patients. However, since BV approval for R/R HL in 2012, many patients are receiving salvage BV before ASCT, alone or combined with chemotherapy. In the AMAHRELIS retrospective nationwide French study, we investigated the real-life outcome of patients with R/R HL mostly treated with BV-based salvage therapies and who received post-ASCT BV maintenance. Objectives : As primary 0objective, we assessed 2 years-PFS of patients treated with post-ASCT BV maintenance from 2012 to 2017 in France. As secondary objectives, we correlated variables (such as use of salvage BV before ASCT, centrally reviewed TEP-assessed response) with survival, and evaluated reported tolerance of BV using the CTCAE v4.0 criteria. Methods : We conducted this observational retrospective study in 58 national centers. Inclusion criteria were R/R HL patients who received at least two infusions of BV after ASCT, at the exclusion of patients in progression after transplant. Among 1134 patients who underwent ASCT for R/R HL between 2012 and 2017 in France based on the French society of bone marrow transplantation database, 835 (74%) patients were screened and data were available for 794 (70%) patients. FDG-PET scan at relapse and before transplantation were recorded and centrally reviewed (still ongoing). FDG-PET scan were reported using the Deauville score (DS), and complete remission was defined by a DS & lt; 4. Post-transplant status was evaluated based on CT-scan or on FDG-PET scan results. This study was approved by the SFGMTC and the LYSA. Results : Fifteen percent (115/794) of patients met eligibility criteria, and were enrolled in this study. Among them, 95% met inclusion criteria for BV maintenance according to the AETHERA study as primary refractory disease (43%), early relapse (27%) or extranodal disease (49%). The mean number of BV injections after ASCT was 11 (3-18). Patients characteristics were : mean age was 34 y (range between 16-70y), 54% were male, and 57% of patients were stage III or IV at relapse. Notably, 70% of patients received BV as salvage therapy and 81% achieved a complete remission before ASCT. The median follow-up period was 35 months. The 2 years survival for the whole cohort was 75,3% for PFS (95% CI : 68,4-84,3) and 96,4% for overall survival (95% CI : 94,2-100) (Figure 1). The use of BV as part of salvage therapy before transplant had no impact on PFS. We observed a trend to an increased occurrence of neuropathy in patients receiving BV before transplant without impact on early treatment discontinuation. We tested several variables for correlation with survival using a univariate Cox model including high risk patients defined as primary refractory disease or early relapse and disseminated disease, extranodal relapse, use of BV before transplant, number of salvage lines, remission status before and after transplant (complete response versus partial response or stable disease), time between ASCT and BV onset and number of BV cycles after transplant. Among these variables, high risk status, less than 10 post transplant BV cycles and absence of post transplant complete remission significantly correlated with a reduced survival probability, and remained significant after analysis using a multivariate Cox model (Table 1). Conclusion : From the real-life AMAHRELIS study, we confirmed the very good outcome of R/R HL patients in the era of post-transplant BV maintenance, with a 2y-PFS of 75% similar to the results of the AETHERA landmark study (2y-PFS of 63%). The results of current strategies with pre- and post-transplant BV outperformed historical series based on high dose therapies, including those of tandem transplant for high risk patients. Future studies incorporating BV strategies with immune checkpoint inhibitors might improve outcome in R/R HL patients.

Abstract: Introduction The IFM 2009 study prospectively evaluated the combination of 8 cycles of lenalidomide, bortezomib and dexamethasone (RVd) versus (vs) 3 cycles of RVd plus high dose (HD) melphalan with autologous stem cell transplantation (ASCT) plus 2 consolidation RVd cycles, followed by lenalidomide maintenance for 12 months (mo) in newly diagnosed multiple myeloma (NDMM) patients (Attal M et al, NEJM 2017). RVd with transplant was associated with significantly longer progression-free survival (PFS) (primary endpoint) compared to RVd alone. Overall survival (OS) at 4 years was similar in both groups. In order to evaluate the long-term outcome in the 2 arms and the impact of 2nd line treatments on PFS2 and OS, we performed an extension of patient follow-up (FU) of the IFM 2009 study over a period of 4 years (DB-FU-IFM 2009 / NCT03679351). Methods 700 NDMM patients (pts) (median age 59 years [range, 28.0-65.0]) were randomized between the 2 arms after stratification by ISS stage and FISH analysis. Patient characteristics were well-balanced, notably age, gender, ISS3, and high risk cytogenetics (defined by t(4;14), t(14;16), del(17p)). 100 patients (50 from each arm) who experienced 1st progression were included in the IFM 2009-02 PCD trial (NCT02244125, Garderet L et al, Blood 2018). The choice of 2nd line treatment and decision to perform an ASCT at relapse was based on investigator's discretion. PFS2 was defined as the time from randomization to progression on next line therapy or death from any cause; second PFS as the time from date of 1st progression to progression on next line therapy or death. This trial was previously reported with a median FU of 44 mo (Attal M et al, NEJM 2017). Results As of March 2020, median FU was 93 mo [range, 88-98]. As previously reported, median PFS was significantly longer in the transplant group (TG), at 47.3 mo compared to 35.0 mo in the RVd alone group (RG) (HR (95CI) 0.70 [0.59-0.83] p & lt;0.001). 497/700 pts experienced disease progression, 270 (77.1%) pts in the RG and 227 (64.9%) pts in the TG; 262 and 217 of them respectively initiated a 2nd line. Among these pts, 76.7% (201/262) in RG and 22.6% (49/217) in TG received an ASCT at 1st relapse; 40.1% (105/262) and 46.5% (101/217) respectively received a pomalidomide-based 2nd line. Only 14 and 12 pts received carfilzomib- and daratumumab-based 2nd line regimens. Median PFS2 was similar in both groups, at 95 mo in the RG and not reached (NR) in the TG (HR [95CI] 0.96 [0.76-1.21] p=0.76). This estimate was homogeneous across ISS stage (p-value for interaction 0.26) and cytogenetic group (p-value for interaction 0.90). Median PFS2 in ISS3 and high-risk cytogenetic pts was 73 and 75 mo, and 48 and 47 mo, in the RG and TG, respectively. Second PFS was significantly increased in the RG, at 36 vs 25 mo in TG (HR [95CI] 1.41 [1.11-1.79] p=0.003). Median OS was NR in either group. At 8 years, the OS rate was 60.2% in the RG and 62.2% in the TG (HR [95CI] 1.03 [0.80-1.32] p=0.81). Minimal residual disease (MRD) was a strong predictor of outcome: PFS (HR [95CI] 0.28 [0.22-0.36] p & lt;0.001), PFS2 (HR [95CI] 0.27 [0.20-0.37] p & lt;0.001) and OS (HR [95CI] 0.35 [0.25-0.49] p & lt;0.001) were longer in pts achieving MRD negativity, in comparison with those who did not. The incidence of invasive 2nd primary cancer was not significantly different between the 2 groups (p=0.38); of note, 2nd hematological malignancies were reported in 5/350 and 7/350 pts in RG and TG respectively. Conclusion RVd before and after HD melphalan and ASCT followed by one-year of lenalidomide maintenance is associated with a significantly longer PFS than RVd alone, without a significant increase of 2nd primary malignancy. At 1st relapse, before the systematic use of daratumumab- or carfilzomib-based combinations, almost half of the pts received pomalidomide-based treatment and about 3 quarters of pts who had not received frontline ASCT underwent delayed transplant. With a FU of almost 8 years, median OS was NR and there was no difference between the 2 strategies with respect to PFS2 and OS. MRD appears to predict outcome and might be used after induction to identify those pts who probably do not require a transplant. Quadruplets with anti-CD38 monoclonal antibodies combined with the selective use of HD therapy and transplant, followed by extended maintenance, should be considered in the future to further improve outcome. Such an approach could potentially provide a functional cure for a significant proportion of NDMM pts.
