The treatment of relapsed/refractory acute myeloid leukemia (AML) is associated with a dismal prognosis. The allogeneic hematopoietic cell transplantation (allo-HCT) is frequently performed as salvage therapy. Reduced intensity conditioning protocols have been developed with the aim of reducing the leukemia burden without increasing their toxicity. We compared the reduced intensity conditioning FM140 (fludarabine, 150 mg/m2; melphalan 140 mg/m2) with FBM110 (fludarabine 150 mg/m2; BCNU, also known as carmustine, 300-400 mg/m2; and melphalan 110 mg/m2). From the European Bone Marrow Transplantation (EBMT) Acute Leukemia Working Party registry, we identified 293 adult patients (FM140, n = 118 and FBM110, n = 175) with AML with relapsed/refractory disease prior to allo-HCT. There were some differences such as age (FM140 = 59.5 years vs. FBM110 = 65.1 years, p < 0.001) and graft-versus-host disease (GvHD) prophylaxis based on in vivo T-cell depletion (TCD, FM140 = 39% vs. FBM110 = 75%, p < 0.001). No differences were observed between FM140- and FBM110-treated patients regarding overall survival (OS) (2-year OS: 39.3% vs. 45.7%, p = 0.58), progression-free survival (PFS) (2-year PFS: 36.1% vs. 37.3%, p = 0.69), non-relapse mortality (NRM) (2-year NRM: 15.3% vs. 25.7%, p = 0.10) and relapse incidence (RI) (2-year RI: 48.6% vs. 37.0%, p = 0.7). In conclusion, despite differences in age and GvHD prophylaxis, AML patients with active disease undergoing allo-HCT after FBM110 conditioning showed similar outcomes compared to FM140.

BACKGROUND: In the phase 3 ALCYONE study, the addition of daratumumab to bortezomib, melphalan, and prednisone (D-VMP) significantly improved outcomes in transplant-ineligible patients with newly diagnosed multiple myeloma. Here, we present results from the final analysis of ALCYONE. METHODS: ALCYONE was an international, multicentre, randomised, open-label, active-controlled, phase 3 trial in adults aged 18 years or older with newly diagnosed multiple myeloma who were ineligible for high-dose chemotherapy with autologous stem-cell transplantation, because of their age (≥65 years) or presence of substantial comorbidities, and had an Eastern Cooperative Oncology Group performance status of 0-2. Patients were enrolled between Feb 9, 2015, and July 14, 2016, and were randomly assigned (1:1) by randomly permuted blocks using an interactive web-based randomisation system to receive bortezomib, melphalan, and prednisone (VMP) alone or D-VMP, with randomisation stratified by International Staging System disease stage, geographical region, and age. Patients received up to nine 6-week cycles of subcutaneous bortezomib (1·3 mg/m2 of body surface area, twice per week on weeks 1, 2, 4, and 5 of cycle 1 and once weekly on weeks 1, 2, 4, and 5 of cycles 2-9), oral melphalan (9 mg/m2, once daily on days 1-4 of each cycle), and oral prednisone (60 mg/m2, once daily on days 1-4 of each cycle). Patients in the D-VMP group also received intravenous daratumumab at a dose of 16 mg/kg once weekly during cycle 1, once every 3 weeks in cycles 2-9, and once every 4 weeks thereafter until disease progression, unacceptably toxicity, or the end of study. The primary endpoint, progression-free survival, has been previously reported. The ALCYONE study has completed; presented here are final analyses for selected secondary endpoints related to overall survival, depth of response, subsequent therapy, and safety. The intention-to-treat population was the primary analysis population (including for overall survival), defined as all patients who were randomly assigned to study treatment. The safety population, consisting of patients who received any dose of study treatment, was used in safety analyses. This trial is registered with ClinicalTrials.gov, NCT02195479. FINDINGS: In total, 706 patients were enrolled and randomly assigned to receive D-VMP (n=350) or VMP (n=356). Baseline characteristics were balanced between the two treatment groups; most participants were female (379 [54%] of 706 patients) and White (601 [85%] of 706 patients). At a median follow-up of 86·7 months (IQR 28·5-85·2), median overall survival was 83·0 months (95% CI 72·5-not estimable) with D-VMP versus 53·6 months (46·3-60·9) with VMP (hazard ratio [HR] 0·65 [95% CI 0·53-0·80]; p<0·0001). The most common grade 3 or 4 treatment-emergent adverse events were neutropenia (140 [40%] of 346 patients in the D-VMP group vs 138 [39%] of 354 patients in the VMP group), thrombocytopenia (120 [35%] vs 134 [38%]), and anaemia (63 [18%] vs 70 [20%]). Serious treatment-related adverse events occurred in 74 (21%) of 346 patients in the D-VMP group and 56 (16%) of 354 patients in the VMP group. Deaths due to treatment-related adverse events occurred in five (1%) of 346 patients in the D-VMP group (pneumonia, acute myocardial infarction, neuroendocrine tumour, tumour lysis syndrome, and acute respiratory failure) and three (1%) of 354 patients in the VMP group (acute myeloid leukaemia, pulmonary embolism, and bacterial pneumonia). INTERPRETATION: With more than 7 years of follow-up, D-VMP continued to elicit clinical benefits in transplant-ineligible patients with newly diagnosed multiple myeloma, supporting the efficacy and safety of frontline daratumumab-based therapy in this patient population.

Většina pacientů s mnohočetným myelomem (MM) je starší 50 let, což je věk, kdy jsou kardiovaskulární nemoci běžné. Proto je třeba být si vědom nežádoucích kardiovaskulárních vlivů protimyelomových léků. Z klasických cytostatik má známý kardiotoxický vliv doxorubicin. Kardiovaskulární komplikace však mohou způsobit také vysoké dávky cyklofosfamidu, používané pro sběr kmenových krvetvorných buněk. Proto se při poškození srdce AL-amyloidózou doporučuje sběr kmenových buněk po G-CSF. Dávky melfalanu, které jsou obvyklé při transplantaci krvetvorné tkáně, mohou taktéž působit negativně na srdce a indukovat arytmie. Ze skupiny inhibitorů proteazomu má nejvíce kardiovaskulárních nežádoucích účinků karfilzomib, po bortezomibu byly popsány v podstatně menší míře, u ixazomibu se kardiotoxicita nepopisuje. U léků ze skupiny IMiD dominuje prokoagulační účinek, vyžadují cílenou profylaxi trombóz a plicních embolií, ale popsány byly i poruchy rytmu. Léčba novými anti-CD38 monoklonálními protilátkami není spojena s evidentní kardiotoxicitou, nežádoucí účinek v oblasti kardiovaskulární se však popisuje u glukokortikoidů, které jsou standardní premedikací při podání anti-CD protilátek. Cílem textu je informovat o incidenci těchto komplikací asociovaných s protimyelomovou léčbou.
Most patients with multiple myeloma (MM) are over 50 years old, which is an age when cardiovascular diseases are common. Therefore, it is important to be aware of the potential adverse cardiovascular effects of anti-myeloma drugs. Among conventional cytostatics, doxorubicin is known for its cardiotoxic effects. High doses of cyclophosphamide, used for stem cell collection, can also cause cardiovascular complications. Therefore, in cases where the heart is affected by AL amyloidosis, stem cell collection after G-CSF is recommended. The doses of melphalan typically used during haematopoietic stem cell transplantation may also have a negative impact on the heart and induce arrhythmias. Among proteasome inhibitors, carfilzomib is associated with the highest number of cardiovascular side effects, while those reported with bortezomib are significantly less frequent, and ixazomib is not associated with cardiotoxicity. In the group of IMiD drugs, procoagulant effects dominate, requiring targeted prophylaxis for thrombosis and pulmonary embolism; however, rhythm disorders have also been reported. Treatment with new anti-CD38 monoclonal antibodies is not linked to evident cardiotoxicity, but adverse cardiovascular effects are associated with glucocorticoids, which are standard premedications for administering anti-CD antibodies. The aim of this text is to inform about the incidence of these complications associated with anti-myeloma treatment.

Melphalan flufenamide (melflufen), a first-in-class alkylating peptide-drug conjugate, plus dexamethasone was approved in Europe for use in patients with triple-class refractory relapsed/refractory multiple myeloma (RRMM) with ≥3 prior lines of therapy and without prior autologous stem cell transplantation (ASCT) or with a time to progression >36 months after prior ASCT. The randomized LIGHTHOUSE study (NCT04649060) assessed melflufen plus daratumumab and dexamethasone (melflufen group) versus daratumumab in patients with RRMM with disease refractory to an immunomodulatory agent and a proteasome inhibitor or who had received ≥3 prior lines of therapy including an immunomodulatory agent and a proteasome inhibitor. A partial clinical hold issued by the US Food and Drug Administration for all melflufen studies led to financial constraints and premature study closure on February 23rd 2022 (data cut-off date). In total, 54 of 240 planned patients were randomized (melflufen group, N=27; daratumumab group, N=27). Median progression-free survival (PFS) was not reached in the melflufen group versus 4.9 months in the daratumumab group (Hazard Ratio: 0.18 [95% Confidence Interval, 0.05-0.65]; P=0.0032) at a median follow-up time of 7.1 and 6.6 months, respectively. Overall response rate (ORR) was 59% in the melflufen group versus 30% in the daratumumab group (P=0.0300). The most common grade ≥3 treatment-emergent adverse events in the melflufen group versus daratumumab group were neutropenia (50% vs. 12%), thrombocytopenia (50% vs. 8%), and anemia (32% vs. 19%). Melflufen plus daratumumab and dexamethasone demonstrated superior PFS and ORR versus daratumumab in RRMM and a safety profile comparable to previously published melflufen studies.

Melphalan flufenamide (melflufen), a first-in-class, alkylating peptide-drug conjugate, demonstrated clinical benefit in combination with dexamethasone in triple-class refractory multiple myeloma (MM). The phase I/IIa ANCHOR study evaluated melflufen (30 or 40 mg) and dexamethasone (40 mg with daratumumab; 20 mg followed by 40 mg with bortezomib; dose reduced if aged ≥75 years) in triplet combination with daratumumab (16 mg/kg; daratumumab arm) or bortezomib (1.3 mg/m2; bortezomib arm) in patients with relapsed/refractory MM refractory to an immunomodulatory agent and/or a proteasome inhibitor and who had received one to four prior lines of therapy. Primary objectives were to determine the optimal dose of melflufen in triplet combination (phase I) and overall response rate (phase IIa). In total, 33 patients were treated in the daratumumab arm and 23 patients received therapy in the bortezomib arm. No dose-limiting toxicities were reported at either melflufen dose level with either combination. With both triplet regimens, the most common grade ≥3 treatment-emergent adverse events were thrombocytopenia and neutropenia; thrombocytopenia was the most common treatment-emergent adverse event leading to treatment discontinuation. In the daratumumab arm, patients receiving melflufen 30 mg remained on treatment longer than those receiving the 40-mg dose. In the daratumumab arm, the overall response rate was 73% and median progression-free survival was 12.9 months. Notably, in the bortezomib arm, the overall response rate was 78% and median progression-free survival was 14.7 months. Considering the totality of the data, melflufen 30 mg was established as the recommended dose for use with dexamethasone and daratumumab or bortezomib for future studies in relapsed/refractory MM.

BACKGROUND: Melflufen, a first-in-class alkylating peptide-drug conjugate, rapidly enters tumor cells and metabolizes to melphalan. In previous studies, melflufen was administered via central venous catheter (CVC). However, administration by peripheral venous catheter (PVC) may be preferable. PATIENTS AND METHODS: PORT was a two-period, phase 2 crossover study of CVC versus PVC melflufen administration in patients with relapsed/refractory multiple myeloma. Adults with ≥ 2 prior therapies refractory to/intolerant of an immunomodulatory drug and a proteasome inhibitor were randomized 1:1 to weekly oral dexamethasone plus melflufen (40 mg) via CVC or PVC infusion on day 1 of 28-day cycle 1. In cycle 2, patients continued dexamethasone and crossed over to the other melflufen administration route. In cycle 3, all patients received melflufen until progression; PVC or CVC routes were allowed based upon investigator decision. Pharmacokinetic sampling was performed during and after melflufen infusion. Primary endpoints were melphalan pharmacokinetic parameters (Cmax, AUC(0-t), and AUC(0-∞)) and frequency and severity of PVC-related local reactions. RESULTS: The 90% CIs for adjusted geometric mean ratios for pharmacokinetic parameters following CVC versus PVC administration were within the 0.8-1.25 bioequivalence range (Cmax 0.946 [90% CI: 0.849, 1.053]; AUC(0-t) 0.952 [90% CI: 0.861, 1.053]; AUC(0-∞) 0.955 [90% CI: 0.863, 1.058]). In both arms, adverse events were primarily hematological and similar; no phlebitis or local infusion-related reactions occurred. CONCLUSION: Melflufen PVC and CVC administrations are bioequivalent based on melphalan pharmacokinetic parameters. Melflufen via PVC was well tolerated, with no infusion-related reactions or new safety signals and may represent an alternative route of administration.

Early relapse (ER) following Autologous Hematopoietic Cell Transplantation (AHCT) confers a poor prognosis. We therefore developed a novel scoring system to predict ER. A total of 14,367 AHCT-1 patients were transplanted between 2014 and 2019, and were conditioned with Melphalan 200 mg/m2 (Mel200) (n = 7228; 2014-2017) (training cohort); Mel200 (n = 5616; 2018-2019) or Mel140 (n = 1523; 2018-2019) (validation cohorts). PFS-12 and the Cumulative Incidence of Relapse at 12 months were 84.1% and 14.7% (training Mel200), 87.2% and 11.6% (validation Mel200), and 80.3% and 16.9% (validation Mel140), respectively. The points in the risk score were: 0, 1,2 for ISS stages I, II, and III; Disease status: 0 (CR/VGPR); 1 (PR); 2 (SD/MR); 4 (Relapse/Progression); and 1 for Karnofsky ≤ 70. The distribution of scores: 0 (24%), 1 (33.9%), 2 (29.6 %), 3 (9.5%), and ≥4 (2.7%). The score separated PFS-12, with the lowest risk group (n = 1752) having a PFS-12 of 91.7% and the highest risk group (n = 195) 57.1%. This also applied in cytogenetically high-risk patients. If the pre-score baseline risks are 15% (standard risk) and 25% (high-risk), a score of ≥4 confers calculated risks of 38% and 54%, respectively. This novel EBMT ER score, therefore, allows for the identification of five discrete prognostic groups.
INTRODUCTION: Melphalan flufenamide (melflufen), a first-in-class alkylating peptide-drug conjugate, plus dexamethasone demonstrated superior progression-free survival (PFS) but directionally different overall survival (OS) favoring pomalidomide (hazard ratio [HR], 1.10) in OCEAN. METHODS: These analyses further investigated prognostic subgroups impacting survival in updated data from the randomized, phase 3 OCEAN study (NCT03151811; date: February 3, 2022) and the phase 2 HORIZON study (NCT02963493; date: February 2, 2022). RESULTS: In OCEAN, subgroups prognostic for OS were age (P = .011; <65 years favored pomalidomide) and no previous autologous stem cell transplant (ASCT) or progression >36 months after ASCT (P = .001; favored melflufen). Overall, 245 of 495 (49%) patients randomized had received a previous ASCT, of which 202 (82%) had progressed within 36 months following their ASCT. When excluding patients who had progressed <36 months post-ASCT (melflufen group, n = 145; pomalidomide group, n = 148), median OS was 23.6 months with melflufen and 19.8 months with pomalidomide (HR, 0.83 [95% CI, 0.62-1.12]; P = .22). Among patients with triple-class refractory disease in HORIZON, patients who had progressed <36 months post-ASCT (n = 58) had a lower response rate and shorter duration of response and PFS than the remaining patients (n = 52). Safety was consistent with previous reports. CONCLUSION: These analyses demonstrate a consistent benefit for melflufen and dexamethasone in patients with relapsed/refractory multiple myeloma who have not received an ASCT or progressed >36 months after receiving an ASCT (ClinicalTrials.gov identifier: NCT03151811).
