The theme of “foundation” runs through political debate and propaganda throughout the 1st century BCE. This contribution revisits the issue of the attribution of the name Augustus to Octavian in January 27 BCE, focusing on reasons put forward by Munatius Plancus, in support of the name Augustus rather than Romulus. Particular attention is given to a key detail: the adjective amplius, which along with novum, characterizes the name Augustus.

Pivekimab sunirine (IMGN632) is a first-in-class antibody–drug conjugate comprising a high-affinity CD123 antibody, cleavable linker, and novel indolinobenzodiazepine pseudodimer payload. CD123 is overexpressed in several haematological malignancies, including acute myeloid leukaemia. We present clinical data on pivekimab sunirine in relapsed or refractory acute myeloid leukaemia. This first-in-human, phase 1/2 dose-escalation and dose-expansion study enrolled participants aged 18 years or older at nine hospitals in France, Italy, Spain, and the USA with CD123+ haematological malignancies (Eastern Cooperative Oncology Group performance status of 0–1); participants reported here were in a cohort of participants with acute myeloid leukaemia who were refractory to or had relapsed on one or more previous treatments for acute myeloid leukaemia. The 3 + 3 dose-escalation phase evaluated two dosing schedules: schedule A (once every 3 weeks, on day 1 of a 3-week cycle) and fractionated schedule B (days 1, 4, and 8 of a 3-week cycle). The dose-expansion phase evaluated two cohorts: one cohort given 0·045 mg/kg of bodyweight (schedule A) and one cohort given 0·090 mg/kg of bodyweight (schedule A). The primary endpoints were the maximum tolerated dose and the recommended phase 2 dose. Antileukaemia activity (overall response and a composite complete remission assessment) was a secondary endpoint. The study is ongoing and registered with ClinicalTrials.gov, NCT03386513. Between Dec 29, 2017, and May 27, 2020, 91 participants were enrolled (schedule A, n=68; schedule B, n=23). 30 (44%) of schedule A participants were female and 38 (56%) were male; 60 (88%) were White, six (9%) were Black or African American, and two (3%) were other races. Pivekimab sunirine at doses of 0·015 mg/kg to 0·450 mg/kg in schedule A was administered in six escalating doses with no maximum tolerated dose defined; three dose-limiting toxicities were observed (reversible veno-occlusive disease; 0·180 mg/kg, n=1 and 0·450 mg/kg, n=1; and neutropenia; 0·300 mg/kg, n=1). Schedule B was not pursued further on the basis of comparative safety and antileukaemia findings with schedule A. The recommended phase 2 dose was selected as 0·045 mg/kg once every 3 weeks. At the recommended phase 2 dose (n=29), the most common grade 3 or worse treatment-related adverse events were febrile neutropenia (three [10%]), infusion-related reactions (two [7%]), and anaemia (two [7%]). Treatment-related serious adverse events occurring in 5% or more of participants treated at the recommended phase 2 dose were febrile neutropenia (two [7%]) and infusion-related reactions (two [7%]). Among 68 participants who received schedule A, one death (1%) was considered to be treatment-related (cause unknown; 0·300 mg/kg cohort). At the recommended phase 2 dose, the overall response rate was 21% (95% CI 8–40; six of 29) and the composite complete remission rate was 17% (95% CI 6–36; five of 29). Pivekimab sunirine showed single-agent activity across multiple doses, with a recommended phase 2 dose of 0·045 mg/kg once every 3 weeks. These findings led to a phase 1b/2 study of pivekimab sunirine plus azacitidine and venetoclax in patients with CD123-positive acute myeloid leukaemia. ImmunoGen.

Procedures to prevent severe graft-versus-host disease (GVHD) delay immune reconstitution secondary to transplants of haploidentical haemopoietic stem cells for the treatment of leukaemia, leading to high rates of late infectious mortality. We aimed to systematically add back genetically engineered donor lymphocytes to facilitate immune reconstitution and prevent late mortality. In a phase I–II, multicentre, non-randomised trial of haploidentical stem-cell transplantation, we infused donor lymphocytes expressing herpes-simplex thymidine kinase suicide gene (TK-cells) after transplantation. The primary study endpoint was immune reconstitution defined as circulating CD3+ count of 100 cells per μL or more for two consecutive observations. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00423124. From Aug 13, 2002, to March 26, 2008, 50 patients (median age 51 years, range 17–66) received haploidentical stem-cell transplants for high-risk leukaemia. Immune reconstitution was not recorded before infusion of TK-cells. 28 patients received TK-cells starting 28 days after transplantation; 22 patients obtained immune reconstitution at median 75 days (range 34–127) from transplantation and 23 days (13–42) from infusion. Ten patients developed acute GVHD (grade I–IV) and one developed chronic GVHD, which were controlled by induction of the suicide gene. Overall survival at 3 years was 49% (95% CI 25–73) for 19 patients who were in remission from primary leukaemia at the time of stem-cell transplantation. After TK-cell infusion, the last death due to infection was at 166 days, this was the only infectious death at more than 100 days. No acute or chronic adverse events were related to the gene-transfer procedure. Infusion of TK-cells might be effective in accelerating immune reconstitution, while controlling GVHD and protecting patients from late mortality in those who are candidates for haploidentical stem-cell transplantation.

BackgroundDaratumumab is a humanized monoclonal antibody approved for the treatment of adult patients with newly diagnosed or relapsed/refractory multiple myeloma (RRMM). Subcutaneous (SC) formulation proved to be non‐inferior in comparison with intravenous (IV) administration route. This study aimed at assessing the economic and time impact associated with the use of SC versus IV daratumumab in patients with RRMM from the perspective of the hematology center.MethodsThis was a 5‐month multicenter time‐and‐motion cross‐sectional micro‐costing study conducted in three Italian hematology centers among adult patients diagnosed with RRMM with ongoing treatment with IV or SC daratumumab. Measurements were performed by an ad hoc App. ResultsNineteen (20%) IV and 76 (80%) SC administration procedures were measured. Patients spent a mean of 4.85 ± 0.91 or 1.08 ± 0.56 h in the hematology center to receive IV or SC daratumumab, respectively. Healthcare professionals (HCPs) spent a mean of 49.38 ± 16.13 and 20.37 ± 7.88 min of active working time to manage IV and SC administrations, respectively. The infusion chair was occupied for a mean of 4.85 ± 0.91 and 0.99 ± 0.55 h during IV or SC administration, respectively. On average, considering the costs due to HCP and chair time, materials, and overhead costs, every IV and SC administration costed €80.33 and 34.90, respectively. ConclusionsIn conclusion, as compared with IV administration, SC daratumumab was associated with 78%, 59%, 80% savings in terms of patient time, HCP active working time, and infusion chair, respectively, and 56.6% budget savings. This study aimed at assessing the economic impact associated with the use of SC versus IV daratumumab in patients with RRMM from the perspective of the hematology center. We found that, as compared with IV administration, SC daratumumab was associated with 78%, 59%, 80% savings in terms of patient time, HCP active working time, and infusion chair, respectively, and 56.6% budget savings.

Initial evidence of CPX-351 activity in patients younger than 60 years emerged from a phase I trial [1]; however, subsequent pivotal phase III trial focused on older patients (≥60 years), where CPX-351 demonstrated superiority over conventional ‘7 + 3’ induction, in in secondary acute myeloid leukemia (sAML), including therapy-related AML (t-AML) and AML with myelodysplasia-related changes (AML-MRC), showing higher overall response rates (ORR), improved overall survival (OS) and increased haematopoetic stem cell transplantation (HSCT) rate [2]. Since CPX-351 is approved for all adult sAML, we conducted a multicentric retrospective study in patients <60. No differences in event-free survival (EFS) were observed according to clinical and laboratory parameters (Supplementary Table S10). [...]those transplanted with active disease had poor outcomes, with mOS of 9.6 months.In the landmark analysis, patients transplanted in first CR had not reached mOS, while no significant OS differences were observed by CK presence (Fig. 2C). The UK NCRI AML19 trial further compared CPX-351 with FLAG-Ida in younger adults with high-risk AML/MDS, showing no OS difference but improved RFS with CPX-351, particularly in patients with MDS-related gene mutations [12].

Background Myeloid neoplasms, including acute myeloid leukemia, have been traditionally among the less investigated cancer types concerning germline predisposition. Indeed, myeloid neoplasms with germline predisposition are challenging to identify because often display similar clinical and morphological characteristics of sporadic cases and have similar age at diagnosis. However, a misidentifications of familiarity in myeloid neoplasms have a critical impact on clinical management both for the carriers and their relatives. Aims We conducted a family segregation study, in order to identify novel cancer predisposing genes in myeloid neoplasms and classify novel identified variants. Methods and Results We performed a thorough genomic analysis using a large custom gene panel (256 genes), the Myelo‐Panel, targeted on cancer predisposing genes. In particular, we assessed both germline and somatic variants in four families, each with two siblings, who developed hematological neoplasms: seven acute myeloid leukemia and one Philadelphia‐positive chronic myeloid leukemia. In each family, we identified at least one novel potentially predisposing variant, affecting also genes not included in the current European LeukemiaNet guidelines for AML management. Moreover, we suggest reclassification of two germline variants as pathogenic: likely pathogenic p.S21Tfs*139 in CEPBA and VUS p.K392Afs*66 in DDX41. Conclusion We believe that predisposition to hematological neoplasms is still underestimated and particularly difficult to diagnosed. Considering that misidentification of familiarity in myeloid neoplasms have a critical impact on the clinical management both for the carriers and their relatives, our study highlights the importance of revision, in this clinical context, of clinical practices that should include thorough reconstruction of family history and in‐depth genetic testing.

Tyrosine kinase inhibitors (TKIs) are the treatment of choice for BCR-ABL1-positive chronic myeloid leukemia (CML). Although TKIs have substantially improved prognosis of CML patients, their use is not free of adverse effects. Dasatinib is a second generation TKI frequently associated with pleural effusion in up to 33% of patients. This results in symptoms as dyspnea, cough and chest pain that may require therapy discontinuation. In the present report, we describe two exceptional cases of HHV8-negative large B-cell effusion-based lymphoma (EBL) confined to the pleura, incidentally, diagnosed in patients presenting with dasatinib-related pleural effusion. One patient (case 1) is alive and is in remission at 17 months from large B-cell EBL diagnosis while unfortunately the other patient (case 2) died of progressive disease and COVID-19 pneumonia 16 months from large B-cell EBL diagnosis. These cases raise concern about a possible association between large B-cell EBL and dasatinib, and the different clinical outcome of the two cases poses a challenge in treatment decision. For this reason, we strongly recommend cytological investigation in patients with persistent/relapsing pleural effusion under dasatinib, primarily to validate its possible association with lymphoma development and to improve the knowledge about this entity.
