RESUMO
BACKGROUND: IMAGE is a retrospective cohort study of patients enrolled in early access programs (EAPs) in France with relapsed/refractory multiple myeloma (RRMM) receiving isatuximab with pomalidomide and dexamethasone (Isa-Pd). METHODS: Patients aged ≥18 years with RRMM who received ≥1 dose of Isa under the EAPs between July 29, 2019 and August 30, 2020 were included. Effectiveness endpoints included progression-free survival (PFS) and response rates. Verbatim terms for adverse events (AEs) were coded using the Medical Dictionary for Regulatory Activities and not graded for severity. RESULTS: A total of 294 and 299 patients were included in the effectiveness and safety populations, respectively. IMAGE included patients who received one prior line of treatment (10.2%) and were daratumumab-refractory (19.1%). At median follow-up of 14.2 months, median PFS in the effectiveness population was 12.4 months (95% CI 9.0-15.0). Overall response and very good partial response rates were 46.3% and 27.9%, respectively. Subgroup analyses reflected similar results. In the safety population, 26.4% of patients reported at least one AE; the most common any-grade AE was neutropenia (9.4%). CONCLUSION: IMAGE demonstrated Isa-Pd had meaningful effectiveness in median PFS and depth of response and no new safety signals in a real-world context, consistent with clinical trial results.

Belantamab mafodotin (BM) is an anti-BCMA antibody-drug conjugate (GSK2857916) that represents an alternative option in multiple myeloma. We sought to assess the efficacy and safety of BM in a real-world setting in patients who benefited from an early access program. We conducted an observational, retrospective, multicenter study. Eligibility criteria were treatment of relapsed or refractory multiple myeloma (RRMM) in monotherapy in adult patients who have received at least three lines of therapy previously, including at least one immunomodulatory agent (IMiD), a proteasome inhibitor (PI) and an anti-CD38 monoclonal antibody, and whose disease progressed during the last treatment period. The primary endpoint of the study is to assess the overall survival (OS). Between November 2019 and December 2020, 106 patients were treated with BM; 97 were eligible for the efficacy evaluation and 104 for safety. The median age was 66 (range, 37-82) years. High-risk cytogenetics were identified in 40.9% of patients. Fifty-five (56.7%) patients were triple-class refractory and 11 (11.3%) were penta-class refractory. The median number of prior lines of treatment was five (range, 3-12). The median number of BM cycles administered was three (range, 1-22). The overall response rate at best response was 38.1% (37/97). The median OS was 9.3 months (95% confidence interval [CI]: 5.9-15.3), and median progression-free survival was 3.5 months (95% CI: 1.9-4.7). The median duration of response was 9 months (range, 4.65-10.4). Treatment was delayed for 55 (52.9%) patients including 36.5% for treatment-related toxicity. Ophthalmic adverse events, mainly grade ≤2, were the most common toxicity (48%). The occurrence of keratopathy was 37.5%. Overall, our data are concordant with the results from DREAMM-2 in terms of efficacy and safety on a non-biased population.

Early identification of ultra-risk diffuse large B-cell lymphoma (DLBCL) patients is needed to aid stratification to innovative treatment. Previous studies suggested high baseline total metabolic tumor volume (TMTV) negatively impacts survival of DLBCL patients. We analyzed the prognostic impact of TMTV and prognostic indices in DLBCL patients, aged 60 to 80 years, from the phase 3 REMARC study that randomized responding patients to R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) into maintenance lenalidomide or placebo. TMTV was computed on baseline positron emission tomography/computed tomography using the 41% maximum standardized uptake value method; the optimal TMTV cutoff for progression-free (PFS) and overall survival (OS) was determined and confirmed by a training validation method. There were 301 out of 650 evaluable patients, including 192 patients classified as germinal center B-cell-like (GCB)/non-GCB and MYC/BCL2 expressor. Median baseline TMTV was 238 cm3; optimal TMTV cutoff was 220 cm3. Patients with high vs low TMTV showed worse/higher Eastern Cooperative Oncology Group performance status (ECOG PS) ≥2, stage III or IV disease, >1 extranodal site, elevated lactate dehydrogenase, International Prognostic Index (IPI) 3-5, and age-adjusted IPI 2-3. High vs low TMTV significantly impacted PFS and OS, independent of maintenance treatment. Although the GCB/non-GCB profile and MYC expression did not correlate with TMTV/survival, BCL2 >70% impacted PFS and could be stratified by TMTV. Multivariate analysis identified baseline TMTV and ECOG PS as independently associated with PFS and OS. Even in responding patients, after R-CHOP, high baseline TMTV was a strong prognosticator of inferior PFS and OS. Moreover, TMTV combined with ECOG PS may identify an ultra-risk DLBCL population. This trial was registered at www.clinicaltrials.gov as #NCT01122472.

BACKGROUND: MDS-RS patients are characterized by chronic anemia and a low risk of Acute Myeloid Leukemia (AML) progression and they generally become Red Blood Cell (RBC) transfusion dependent (TD). STUDY DESIGN AND METHODS: We performed a retrospective "real-life" observational study of 6 months in 100 MDS-RS TD patients, recruited in 12 French centers, to describe transfusion characteristics, and evaluate the frequency and causes of hospitalizations, health costs, and morbidity, associated with transfusion dependency, in a French population of RBC transfusion-dependent MDS-RS patients. RESULTS: 79% of the patients had high transfusion burden (HTB) and 21% low transfusion burden (LTB). HTB patients had a longer disease duration (6 vs. 3.7 years, p = 0.0078), more frequent iron chelation (82% vs. 50%, p = 0.0052) and higher serum ferritin (p = 0.03). During the 6-month study period, 22% of the patients required inpatient hospitalization, 36% of them for symptomatic anemia requiring emergency RBC transfusion. The 6-month median transfusion costs, including the cost of the day care facility, transportation to and from the hospital, iron chelation, and lab tests, was 16,188/patient. DISCUSSION: MDS-RS represents the archetypal type of chronically transfused lower-risk MDS. Most of those patients have a high transfusion burden and thus frequently need visits to the hospital's day care facility, and frequent hospitalizations, with an overall high median treatment cost. Those costs should be compared with costs of new treatments potentially able to avoid RBC transfusion dependence and to reduce the complications of chronic anemia in MDS-RS patients.

Lenalidomide maintenance therapy prolonged progression-free survival (PFS) versus placebo in elderly patients with diffuse large B-cell lymphoma (DLBCL) responding to induction chemotherapy in the phase 3 REMARC study. This subpopulation analysis assessed the impact of lenalidomide maintenance and treatment-emergent adverse events (TEAEs) on health-related quality of life (HRQOL). Global health status (GHS), and physical functioning and fatigue subscales were evaluated in patients who completed the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire-C30 v3.0. The impact of TEAEs classified post hoc as subjective (patients can feel) or observable (only measurable by physicians) on dose reductions and discontinuations was assessed. Among 457 patients (lenalidomide, n = 229; placebo, n = 228), mean (standard deviation) GHS was similar between treatment arms [68·2 (20·7) Versus 72·0 (17·8)] at randomisation and remained similar during maintenance. Patients receiving lenalidomide experienced no meaningful changes in GHS, physical functioning, or fatigue. Observable TEAEs were more common (81·1% Versus 66·3%) and more likely to lead to dose reductions, than subjective TEAEs in both arms. PFS was superior in the lenalidomide arm regardless of dose reduction. Lenalidomide maintenance prolonged PFS and did not negatively impact HRQOL in patients with DLBCL despite TEAEs being more common, when compared with placebo.

Erythropoiesis-stimulating agents are generally the first line of treatment of anemia in patients with lower-risk myelodysplastic syndrome. We prospectively investigated the predictive value of somatic mutations, and biomarkers of ineffective erythropoiesis including the flow cytometry RED score, serum growth-differentiation factor-15, and hepcidin levels. Inclusion criteria were no prior treatment with erythropoiesis-stimulating agents, low- or intermediate-1-risk myelodysplastic syndrome according to the International Prognostic Scoring System, and a hemoglobin level <10 g/dL. Patients could be red blood cell transfusion-dependent or not and were given epoetin zeta 40 000 IU/week. Serum erythropoietin level, iron parameters, hepcidin, flow cytometry Ogata and RED scores, and growth-differentiation factor-15 levels were determined at baseline, and molecular analysis by next-generation sequencing was also conducted. Erythroid response (defined according to the International Working Group 2006 criteria) was assessed at week 12. Seventy patients, with a median age of 78 years, were included in the study. There were 22 patients with refractory cytopenia with multilineage dysplasia, 19 with refractory cytopenia with unilineage dysplasia, 14 with refractory anemia with ring sideroblasts, four with refractory anemia with excess blasts-1, six with chronic myelomonocytic leukemia, two with del5q-and three with unclassifiable myelodysplastic syndrome. According to the revised International Prognostic Scoring System, 13 had very low risk, 47 had low risk, nine intermediate risk and one had high-risk disease. Twenty patients were transfusion dependent. Forty-eight percent had an erythroid response and the median duration of the response was 26 months. At baseline, non-responders had significantly higher RED scores and lower hepcidin:ferritin ratios. In multivariate analysis, only a RED score >4 (P=0.05) and a hepcidin:ferritin ratio <9 (P=0.02) were statistically significantly associated with worse erythroid response. The median response duration was shorter in patients with growth-differentiation factor-15 >2000 pg/mL and a hepcidin:ferritin ratio <9 (P=0.0008 and P=0.01, respectively). In multivariate analysis, both variables were associated with shorter response duration. Erythroid response to epoetin zeta was similar to that obtained with other erythropoiesis-stimulating agents and was correlated with higher baseline hepcidin:ferritin ratio and lower RED score. ClinicalTrials.gov registration: NCT 03598582.

(90) Yttrium ((90) Y)-Ibritumomab-Tiuxetan combines the targeting advantage of a monoclonal antibody with the radiosensitivity of Follicular Lymphoma (FL). Previous studies showed that 90Y-IT is safe and effective in relapsed/refractory indolent FL, irrespective of prior treatment with rituximab. This multicentre trial aimed to evaluate the safety and the efficacy of "upfront" single-agent ((90) Y)-Ibritumomab-Tiuxetan in advanced-stage FL. The primary objective was the incidence of responses in terms of complete (CR) and partial remission (PR). Fifty patients with stage II "bulky", III or IV FL received a single treatment course with ((90) Y)-Ibritumomab-Tiuxetan as initial therapy. The median age was 60 years. Bone marrow involvement (<25%) was observed in 24 patients (48%) and 7 (14%) had an elevated lactate dehydrogenase level. The overall response (ORR) and CR rates were 94% and 86%, respectively with a median follow-up of 38·8 months. The median progression-free survival (PFS) was not reached, whereas the 3-year estimated PFS and overall survival (OS) rate was 63·4% and 90%, respectively. Grade 3/4 neutropenia and thrombocytopenia occurred in 30% and 26% of patients respectively; none experienced grade 3/4 non-haematological toxicity. No cases of secondary haematological malignancies were observed. ((90) Y)-Ibritumomab-Tiuxetan was demonstrated to be highly effective and safe as first-line treatment for advanced-stage FL.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The primary analysis of the Ro-CHOP phase III randomized controlled trial (ClinicalTrials.gov identifier: NCT01796002) established that romidepsin (Ro) plus cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) did not yield an increased efficacy compared with CHOP alone as first-line treatment of peripheral T-cell lymphoma. We report the planned final analysis 5 years after the last patient enrolled. With a median follow-up of 6 years, median progression-free survival (PFS) was 12.0 months compared with 10.2 months (hazard ratio [HR], 0.79 [95% CI, 0.62 to 1.005]; P = .054), while median overall survival was 62.2 months (35.7-86.6 months) and 43.8 months (30.1-70.2 months; HR, 0.88 [95% CI, 0.68 to 1.14]; P = .324) in the Ro-CHOP and CHOP arms, respectively. In an exploratory analysis, the median PFS in the centrally reviewed follicular helper T-cell lymphoma subgroup was significantly longer in the Ro-CHOP arm (19.5 v 10.6 months, HR, 0.703 [95% CI, 0.502 to 0.985]; P = .039). Second-line treatments were given to 251 patients with a median PFS2 and OS2 after relapse or progression of 3.3 months and 11.5 months, respectively. Within the limits of highly heterogeneous second-line treatments, no specific regimen seemed to provide superior disease control. However, a potential benefit was observed with brentuximab vedotin in association with chemotherapy even after excluding anaplastic large-cell lymphoma subtype or after adjusting for histology and international prognostic index in a multivariate model (HR for PFS, 0.431 [95% CI, 0.238 to 0.779]; P = .005).

ABSTRACT: Real-world data (RWD) are essential to complement clinical trial (CT) data, but major challenges remain, such as data quality. REal world dAta in LYmphoma and Survival in Adults (REALYSA) is a prospective noninterventional multicentric cohort started in 2018 that included patients newly diagnosed with lymphoma in France. Herein is a proof-of-concept analysis on patients with first-line diffuse large B-cell lymphoma (DLBCL) to (1) evaluate the capacity of the cohort to provide robust data through a multistep validation process; (2) assess the consistency of the results; and (3) conduct an exploratory transportability assessment of 2 recent phase 3 CTs (POLARIX and SENIOR). The analysis population comprised 645 patients with DLBCL included before 31 March 2021 who received immunochemotherapy and for whom 3589 queries were generated, resulting in high data completeness (<4% missing data). Median age was 66 years, with mostly advanced-stage disease and high international prognostic index (IPI) score. Treatments were mostly rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone (R-CHOP 75%) and reduced dose R-CHOP (13%). Estimated 1-year event-free survival (EFS) and overall survival rates were 77.9% and 90.0%, respectively (median follow-up, 9.9 months). Regarding transportability, when applying the CT's main inclusion criteria (age, performance status, and IPI), outcomes seemed comparable between patients in REALYSA and standard arms of POLARIX (1-year progression-free survival 79.8% vs 79.8%) and SENIOR (1-year EFS, 64.5% vs 60.0%). With its rigorous data validation process, REALYSA provides high-quality RWD, thus constituting a platform for numerous scientific purposes. The REALYSA study was registered at www.clinicaltrials.gov as #NCT03869619.

PURPOSE: Rituximab improves progression-free survival (PFS) and time to next treatment (TTNT) when compared with the watch and wait strategy for patients with low-tumor burden follicular lymphoma (FL). Prolonged rituximab maintenance did not prolong TTNT, whereas it raises concerns about resources use and patient adhesion. Our aim was then to investigate the use of short rituximab maintenance using the subcutaneous (SC) route in patients with low-tumor burden FL. METHODS: Patients with histologically confirmed CD20+ low-tumor burden FL were randomly assigned to receive either rituximab, 375 mg/m2 once daily on D1, D8, D15, and D22, intravenous route (IV, control arm), or rituximab, 375 mg/m2, on day 1 (D1), IV followed by rituximab 1,400 mg total dose, SC once daily on D8, D15, and D22, with maintenance at months 3 (M3), M5, M7, and M9 (experimental arm). The primary end point was PFS. Secondary end points included safety, overall response rates, TTNT, and overall survival (OS). RESULTS: Two hundred two patients with low-tumor burden FL were randomly assigned to the experimental (n = 100) or control arm (n = 102). The primary end point was met: the 4-year PFS was 58.1% (95% CI, 47.5 to 67.4) and 41.2% (95% CI, 30.6 to 51.6) in experimental and control arms, respectively (hazard ratio, 0.585 [0.393 to 0.871]; P = .0076). Complete response (CR) rates were 59.0% (95% CI, 48.7 to 68.7) in the experimental arm and 36.3% (95% CI, 27.0 to 46.4) in the control arm (P = .001). TTNT and OS were not significantly different. CR was associated with longer PFS and TTNT. High rituximab exposure during the first three months was independently associated with higher CR, PFS, and TTNT. CONCLUSION: SC rituximab improves PFS for patients with low-tumor burden FL when used in induction followed by short maintenance. High rituximab exposure during the first 3 months after treatment initiation is, however, the only parameter influencing patient outcomes.

PURPOSE: Romidepsin, a histone deacetylase inhibitor, has demonstrated activity in relapsed or refractory peripheral T-cell lymphoma (PTCL) as a single agent. Cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) therapy is widely used as first-line treatment of PTCL; however, it has limited efficacy. Results from a phase Ib and II study showed the feasibility of combining romidepsin with CHOP (Ro-CHOP). METHODS: This study is a randomized phase III study of Ro-CHOP versus CHOP in adult patients with previously untreated PTCL. All patients received CHOP in 3-week cycles for six cycles. Romidepsin, 12 mg/m2, was administered intravenously over a 4-hour period on days 1 and 8 of each 3-week cycle for six cycles. The primary end point was progression-free survival (PFS) according to International Working Group 1999 criteria. RESULTS: Between January 2013 and December 2017, 421 patients were enrolled (Ro-CHOP, n = 211; CHOP, n = 210). The median PFS for Ro-CHOP versus CHOP was 12.0 months (95% CI, 9.0 to 25.8) versus 10.2 months (95% CI, 7.4 to 13.2) with a hazard ratio of 0.81 (P = .096). In the Ro-CHOP versus CHOP arms, the median overall survival was 51.8 versus 42.9 months and the objective response rate was 63% versus 60% with complete response plus unconfirmed complete response rates of 41% versus 37% (P > .1 in all comparisons), respectively. Grade 3 or 4 treatment-emergent adverse events occurring in ≥ 30% of patients in the Ro-CHOP arm included thrombocytopenia (50% v 10% in the Ro-CHOP v CHOP arms, respectively), neutropenia (49% v 33%), anemia (47% v 17%), and leukopenia (32% v 20%). CONCLUSION: The addition of romidepsin to CHOP did not improve PFS, response rates, nor overall survival and increased the frequency for grade ≥ 3 treatment-emergent adverse events. Ro-CHOP does not represent a significant advance in the standard of care for patients with previously untreated PTCL.

The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.The RELEVANCE trial (ClinicalTrials.gov identifier: NCT01650701) showed that lenalidomide plus rituximab (R2) provided similar efficacy to rituximab plus chemotherapy (R-chemo) in patients with advanced-stage, previously untreated follicular lymphoma (FL). We report the second interim analysis of the RELEVANCE trial after 6 years of follow-up. Patients with previously untreated grade 1-3a FL were assigned 1:1 to R2 or R-chemo, followed by rituximab maintenance. Coprimary end points were complete response (confirmed/unconfirmed) at week 120 and progression-free survival (PFS). At median follow-up of 72 months, 6-year PFS was 60% and 59% for R2 and R-chemo, respectively (hazard ratio = 1.03 [95% CI, 0.84 to 1.27]). Six-year overall survival was estimated to be 89% in both groups. Median PFS and overall survival were not reached in either group. Overall response after progression was 61% and 59%, and 5-year estimated survival rate after progression was 69% and 74% in the R2 and R-chemo groups, respectively. The transformation rate per year in the R2 and R-chemo groups was 0.68% and 0.45%, and secondary primary malignancies occurred in 11% and 13% (P = .34), respectively. No new safety signals were observed. R2 continues to demonstrate comparable, durable efficacy and safety versus R-chemo in previously untreated patients with FL and provides an acceptable chemo-free alternative.

In this retrospective study, we report 70 cases of Epstein-Barr virus (EBV)+ diffuse large B-cell lymphoma not otherwise specified (DLBCL-NOS) among 1696 DLBCL-NOS cases diagnosed between 2006 and 2019 (prevalence of 4.1%). At diagnosis, median age was 68.5 years; 79% of the cases presented with an advanced-stage disease (III-IV), 48% with extranodal lesions, and 14% with an hemophagocytic lymphohistiocytosis (HLH) (8 at diagnosis and 1 on therapy). A total of 46 cases presented a polymorphic pattern, and 21 were monomorphic. All had a non-germinal center B phenotype, with the majority of tumor cells expressing CD30 and programmed death ligand 1 (98% and 95%, respectively). Type II and III EBV latency was seen in 88% and 12% of the cases, respectively. Patients were treated with immunochemotherapy (59%) or chemotherapy (22%), and 19% received palliative care due to advanced age and altered performance status. After a median follow-up of 48 months, progression-free survival (PFS) and overall survival (OS) at 5 years were 52.7% and 54.8%, respectively. Older age (>50 years) and HLH were associated with shorter PFS and OS in multivariate analysis (PFS: hazard ratio [HR], 14.01; 95% confidence interval [CI], 2.34-83.97; and HR, 5.78; 95% CI, 2.35-14.23; OS: HR, 12.41; 95% CI, 1.65-93.53; and HR, 6.09; 95% CI, 2.42-15.30, respectively). Finally, using a control cohort of 425 EBV- DLBCL-NOS, EBV positivity was associated with a shorter OS outcome within patients >50 years (5-year OS, 53% [95% CI, 38.2-74] vs 60.8% [95% CI, 55.4-69.3], P = .038), but not in younger patients.

PURPOSE: The prognosis of elderly patients with diffuse large B-cell lymphoma (DLBCL) is worse than that of young patients. An attenuated dose of chemotherapy-cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab (R-miniCHOP)-is a good compromise between efficacy and safety in very elderly patients. In combination with R-CHOP (R2-CHOP), lenalidomide has an acceptable level of toxicity and may mitigate the negative prognosis of the non-germinal center B-cell-like phenotype. The Lymphoma Study association conducted a multicentric, phase III, open-label, randomized trial to compare R-miniCHOP and R2-miniCHOP. PATIENTS AND METHODS: Patients of age 80 years or older with untreated DLBCL were randomly assigned into the R-miniCHOP21 group or the R2-miniCHOP21 group for six cycles and stratified according to CD10 expression and age. The first cycle of rituximab was delivered by IV on D1 after a prephase and then delivered subcutaneously on D1 of cycles 2-6. Lenalidomide was delivered at a dose of 10 mg once daily on D1-D14 of each cycle. The primary end point was overall survival (OS). RESULTS: A total of 249 patients with new DLBCL were randomly assigned (127 R-miniCHOP and 122 R2-miniCHOP). The median age was 83 years (range, 80-96), and 55% of the patients were classified as non-GCB. The delivered dose for each R-miniCHOP compound was similar in both arms. Over a median follow-up of 25.1 months, the intention-to-treat analysis revealed that R2-miniCHOP did not improve OS (2-year OS 66% in R-miniCHOP and 65.7% in R2-miniCHOP arm, P = .98) in the overall population or in the non-GCB population. Grade 3-4 adverse events occurred in 53% of patients with R-miniCHOP and in 81% of patients with R2-miniCHOP. CONCLUSION: The addition of lenalidomide to R-miniCHOP does not improve OS. Rituximab delivered subcutaneously was safe in this population.

Thrombotic microangiopathies are rare diseases characterized by an initial endothelial injury and the formation of thrombi in the microcirculation. Several types of thrombotic microangiopathies can be distinguished: the thrombotic thrombocytopenic purpura; the hemolytic and uremic syndrome, mainly "typical" following a shiga toxin-producing Escherichia coli infection or "atypical" due to a dysregulation of the alternative complement pathway; and "secondary" thrombotic microangiopathies. The use of drug treatments is reported as a frequent cause in this last category and requires stopping the offending drug. We report the case of a patient who developed "secondary" hemolytic and uremic syndrome associated with carfilzomib, a proteasome inhibitor which is used in case of multiple myeloma relapses. Besides stopping the treatment, the patient still showed signs of hemolysis and renal failure with anuria requiring hemodialysis. An eculizumab treatment was therefore initiated. The overall evolution was favorable and an improvement of the renal function promptly allowed the discontinuation of hemodialysis. We discuss the mechanisms that may activate the alternative complement pathway and the potential interest of a transient use of eculizumab in case of carfilzomib-induced hemolytic and uremic syndrome.

Complete molecular response (CMR) after first-line immunochemotherapy reflects treatment efficacy and may predict prognosis in patients with follicular lymphoma (FL). RELEVANCE is the first phase 3 trial comparing the chemotherapy-free regimen lenalidomide/rituximab (R2) vs rituximab/chemotherapy (R-Chemo) in previously untreated FL patients (ClinicalTrials.gov identifier: NCT01650701). The objective of the minimal residual disease (MRD) analysis was to determine the ability of a chemotherapy-free regimen to induce CMR. Of 440 French patients participating in the Lymphoma Study Association (LYSA) RELEVANCE MRD study, all 222 patients with a BIOMED-2-detectable BCL2-JH translocation at diagnosis were analyzed. MRD was quantified by droplet digital polymerase chain reaction with a sensitivity ≤10-4. At week 24 (end of induction treatment), 98% and 78% of patients achieved CMR in peripheral blood (PB) and bone marrow (BM), respectively. Achievement of CMR (in PB and/or BM) had a significant impact on progression-free survival (PFS), with 3-year PFS of 84% and 55% for patients with CMR and detectable MRD, respectively (P = .015). CMR at week 24 was reached more frequently in the R2 arm (105/117; 90%) than in the R-Chemo arm (70/90; 77%) (P = .022). The poor prognostic value in terms of PFS for the persistence of molecular disease was observed irrespective of treatment arm (interaction test, P = .31). In agreement with the clinical results of the RELEVANCE trial, our results show that R2 immunomodulatory treatment in first-line FL can achieve high rates of CMR.

OBJECTIVES: Bortezomib has proven to be effective as single agent in myeloma patients. Aim of this study was to evaluate the efficacy and toxicity of bortezomib in combination with dexamethasone in a cohort of multiple myeloma (MM) relapsed/refractory patients treated in a single center. PATIENTS AND METHODS: In this single center study, 70 patients were treated with bortezomib alone (9) or in combination with dexamethasone (61). RESULTS: Forty-one patients (59%) achieved at least a partial response (PR), including 7% complete response (CR), 36% very good partial response (VGPR) reaching the best response within four cycles. The duration of response was significantly longer for patients achieving CR/VGPR than for those achieving PR (7.3 vs. 3.8 months, P = 0.03). Likewise, time to progression, time to alternative treatment, and treatment free interval were significantly better for patients obtaining CR/VGPR (6.8, 9.4, 6.5 months respectively) as compared with PR (4.9, 6.3, 2 months respectively). The only dose-limiting toxicity was peripheral neuropathy (PN), which occurred in 38/70 patients (55%) and was of grade 3-4 in 12 (17%). PN led to a dose reduction or treatment discontinuation in 17 (24%) patients. Complete resolution or improvement of PN occurred in 29/38 (76%) after a median time of 100 d (range: 17-202). CONCLUSIONS: Bortezomib in combination with dexamethasone is highly effective in relapsed/refractory MM producing an impressive rate of CR/VGPR, but responses are short-lived.

Ruxolitinib was recently approved for the treatment of patients with polycythemia vera who are resistant/intolerant to hydroxyurea based on data from the RESPONSE studies. This phase 3b, Expanded Treatment Protocol study (NCT02292446) of ruxolitinib for hydroxyurea-resistant/intolerant patients with polycythemia vera (N = 161: median exposure = 25.1 weeks) further evaluated the safety of ruxolitinib. Adverse events (AEs) led to dose adjustment/interruption in 37.9% of patients and study drug discontinuation in 8.7% of patients. The most common hematologic AEs included anemia and thrombocytosis; while headache and diarrhea were the most frequent nonhematologic AEs. At week 24, 45.3% of patients achieved hematocrit control; hematologic remission was seen in 18% of patients. At least, 50% of reduction in spleen length was achieved in 86.7% of patients from baseline at any time. The observed safety profile of ruxolitinib was consistent and the efficacy results were similar to the observed values in the RESPONSE studies.

BACKGROUND: Myelofibrosis and acquired hemophilia A is a rare association. To the best of our knowledge only one case of myelofibrosis and acquired hemophilia A has been previously described. CASE PRESENTATION: A 66-year-old Caucasian man diagnosed with myelofibrosis evolving in acute myeloid leukemia was referred to us for postoperative bleeding. Hemostatic studies showed prolonged activated partial thromboplastin time, decreased factor VIII coagulation, and a high factor VIII inhibitor titer; these findings led to a diagnosis of acquired hemophilia A for which he was treated with methylprednisolone and recombinant activated factor VII on admission. Due to a lack of response he was subsequently treated with rituximab combined with activated prothrombin complex concentrates. Furthermore, he received azacytidine to treat the underlying hematological malignancies. Immunosuppressive rituximab therapy resolved acquired hemophilia A with marked efficacy. CONCLUSIONS: Rapid and accurate diagnosis, effective hemostatic therapy, and timely treatment for underlying disease are important in the management of acquired hemophilia A secondary to hematological malignancy.

We compared the clinical value of minimal residual disease (MRD) monitoring by cytofluorimetric methods, Wilms tumor gene 1 (WT1) expression and the study of nucleophosmin gene (NPM) mutations in a series of 26 patients with NPM-mutated de novo acute myeloid leukemia (NPM-AML) who achieved complete hematological remission after conventional chemotherapy. The relapse risk was significantly lower only in patients achieving a NPM molecular complete response (NPM mol-CR) and confirmed NPM mol-CR (non-detectable NPM mutations in two consecutive marrow samples). The disease-free survival (DFS) of patients achieving a < 4-log or ≥ 4-log reduction in NPM value after induction therapy was 12.6 % and 50%, respectively, at 36 months (p = 0.009). The attainment of a confirmed NPM-CR had a significant influence on overall survival (OS at 36 months was 64.3% and 11.9% in patients obtaining or not obtaining confirmed NPM-CR, respectively, p < 0.03). We confirm that NPM-molecular relapse (NPM-rel) is always followed by hematological relapse (H-rel), but longitudinal studies of NPM mutations may predict an impending H-rel earlier than flow cytometric- or WT1-based methods.
