It poses substantial classification and management dilemmas. Herein, we report a large cohort of acute leukemia with a mixed phenotype and define Acute Myeloid Leukemia with Mixed Phenotype (AML-MP) and MPAL as two distinct groups by characterizing the clinical, genetic, and transcriptomic features. Clinically, patients with AML-MP and MPAL were both treated with either AML- or acute lymphoblastic leukemia (ALL)-directed induction regimens. AML-MP shows inferior responses (HR, 12.5; 95% CI, 2.72-57.8; p=.001), while MPAL shows better responses to ALL-directed treatment. Genetically, AML-MP harbors more frequent RUNX1 (23/52, 44%) and TP53 (12/52, 23.1%) mutations. In contrast, RUNX1 mutations are less frequent in MPAL (8/35, 23%, p=.01 vs AML-MP) and TP53 mutations as a driver are virtually absent in MPAL. Transcriptionally, AML-MP shows enrichment for stemness signatures, and a relative deficit of transcription factors critical for myeloid and lymphoid differentiation. Furthermore, AML-MP rarely switches to a lymphoid immunophenotype after treatment, in contrast to MPAL (1/40, 2.5%, vs. 10/28, 35.7%, p=.0003). Lastly, a genomic classification framework is proposed for future studies. Together, these data support the designation of AML-MP as a diagnosis distinct from MPAL and provide novel insights into the pathogenesis and therapies of acute leukemia with a mixed phenotype.","PeriodicalId":9102,"journal":{"name":"Blood","volume":"30 1","pages":""},"PeriodicalIF":20.3,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This phase 1, open-label study investigated the safety and efficacy of prizlon-cel in patients with relapsed/refractory B-cell non-Hodgkin Lymphoma (r/r B-NHL). Patients with CD19 and/or CD20-positive r/r B-NHL received a 3-day lymphodepletion (cyclophosphamide: 300 mg/m2/d; fludarabine: 30 mg/m2/d) followed by an intravenous dose of prizlon-cel. The primary endpoints were dose-limiting toxicity (DLT) and incidence and severity of treatment-emergent adverse events (TEAEs). Secondary endpoints included overall response rate (ORR), duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Of the 48 patients infused prizlon-cel, 44 had large B-cell lymphoma (LBCL). No patient experienced DLT. Cytokine release syndrome occurred in 93.8% of patients, with only one case of grade 3. Immune effector cell-associated neurotoxicity syndrome occurred in 6.3% of patients, with no grade 3 or higher events. The most common grade 3 or higher TEAEs were neutropenia (83.3%) and leukopenia (50%). The ORR and complete response (CR) rates in all patients were 91.5% and 85.1%, respectively, and in LBCL patients, ORR was 90.7% with 86.0% CR. With median follow up of 30.0 months, median DOR, PFS, and OS were all not reached. The Kaplan-Meier estimate of 2-year DOR, PFS and OS rates were 66.0%, 62.6%, and 76.5%, respectively. Prizlon-cel showed a favorable safety profile and a high and durable response in patients with r/r B-NHL, suggesting a promising treatment option for patients with r/r B-NHL.

Its common germline variants APOE2, APOE3 and APOE4 give rise to three functionally distinct gene products. Previous studies reported yin-yang roles of APOE2 and APOE4 in immunological processes, but their effects in hematopoietic stem cell transplantation (HSCT) have never been studied. We performed APOE genotyping in two contemporary cohorts of 348 and 447 patients with acute myeloid leukemia (AML) who had received allogeneic HSCT and evaluated associations of recipient and donor APOE genetic variation with posttransplant outcome. Patients who carried at least one APOE2 allele had a higher risk of posttransplant death compared to APOE4 carriers in the discovery (hazard ratio [HR] 2.09, P = .024) and validation cohorts (HR 1.96, P = .040). Detrimental APOE2 effects were driven by an increased risk of severe chronic graft-versus-host disease (GvHD; HRadj 1.85, P = .034) and non-relapse death (HRadj 1.72, P = .044). In non-APOE2 recipients, transplantation of an APOE2-positive allograft was associated with an increased incidence of grade III-IV acute GvHD (HRadj 2.82, P = .012) and severe chronic GvHD (HRadj 2.54, P = .022) compared to APOE2-negative grafts. In summary, the APOE2 allele, typically considered a longevity gene in the general population, was associated with a higher risk of acute GvHD (HRadj 2.75, P = .002), chronic GvHD (HRadj 2.57, P = .001), and posttransplant mortality (HRadj 1.79, P = .004), when present either in the host or transplanted from the donor.","PeriodicalId":9102,"journal":{"name":"Blood","volume":"45 1","pages":""},"PeriodicalIF":20.3,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142988649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
