In this week's episode, we’ll learn more about relationships between Epstein-Barr virus genomic variants and human diseases, including hematological malignancies; the presence and timing of somatic GATA1 mutations and their relationship to a Down syndrome-specific form of leukemia; and new definitions for high-risk multiple myeloma that emphasize the presence of two or more high-risk cytogenetic abnormalities.Featured Articles:Association of Epstein-Barr virus genomic alterations with human pathologiesClinical significance of preleukemic somatic GATA1 mutations in children with Down syndromeBiallelic antigen escape is a mechanism of resistance to anti-CD38 antibodies in multiple myeloma
In this Review Series episode, Associate Editor Dr. Hervé Dombret speaks with Dr. Mark Litzow about the latest immunotherapy advances for Acute Lymphoblastic Leukemia (ALL). The discussion highlights innovative treatments like blinatumomab and inotuzumab, which are showing remarkable success in clinical trials, including an 85% three-year survival rate and over 90% complete remission in elderly patients. Researchers are focusing on reducing chemotherapy intensity, developing personalized treatment approaches, and identifying optimal immunotherapy strategies for different ALL subtypes. The conversation underscores a promising shift towards more targeted, less toxic treatments that could significantly improve patient outcomes across various age groups and disease characteristics. These emerging therapies represent a potential paradigm shift in ALL treatment, offering hope for more effective and less aggressive therapeutic interventions.Read Dr. Litzow's paper “Incorporation of immunotherapy into frontline treatment for adults with B-cell precursor acute lymphoblastic leukemia” or find the whole review series on acute lymphoblastic leukemia in volume 145 issue 14 of Blood Journal.
In this week's episode we'll learn about Azacitidine in VEXAS syndrome. Treatment can provide responses in patients with this complex autoinflammatory disorder. But relapse rates were high, so long-term therapy may be required to maintain disease control. After that: A step forward in precision blood matching. High-throughput array genotyping enables extended matching to reduce antibody formation. The results show the potential for reducing harm in regularly transfused patients. Finally, identifying a new vulnerability in TP53-mutated AML. Loss of the tumor suppressor BAP1 defines a unique subtype of TP53-mutated de novo AML. BAP1 loss also confers sensitivity to BCL-xL inhibitors in vivo, opening a new therapeutic avenue.Featured ArticlesEfficacy and safety of azacitidine for VEXAS syndrome: a large-scale retrospective study from FRENVEXArray genotyping of transfusion-relevant blood cell antigens in 6946 ancestrally diverse study participantsLoss of BAP1 defines a unique subtype of TP53-mutated de novo AML and confers sensitivity to BCL-xL inhibitors
In this week's episode we'll learn about persistent changes in immune profiles in patients who have had diffuse large B-cell lymphoma, or DLBCL, and other cancers; that plasminogen activation and plasmin activity do not appear to play a role in routine physiological prevention of venous thromboembolism, or VTE; and about a novel mechanism that makes hematological malignancies carrying epigenetic mutations susceptible to PARP inhibitors.Featured Articles:Large B-cell lymphoma imprints a dysfunctional immune phenotype that persists years after treatmentPlasminogen activation and plasmin activity are not required to prevent venous thrombosis/thromboembolismTransposable elements as novel therapeutic targets for PARPi-induced synthetic lethality in PcG-mutated blood cancer
In this week's episode, we'll learn about how TET2 is often mutated in myeloid malignancies and clonal hematopoiesis. In new work, expansion of Tet2-mutant HSPCs was dependent on Ncoa4, the cargo receptor mediating ferritinophagy. We’ll iron out the implications. After that: a double-oh-seven license to kill in T-cell leukemia/lymphoma. WU-CART-007 is an off-the-shelf CAR T product with manageable safety and encouraging efficacy. With further work, it could become a new option for patients in urgent need of therapy. Finally: a comprehensive genetic study of classical Hodgkin lymphoma using circulating tumor DNA. This new research provides novel and complex insights on genetic subtypes, prognostic biomarkers, neoantigens in the disease environment, and more.Featured Articles:An in vivo barcoded CRISPR-Cas9 screen identifies Ncoa4-mediated ferritinophagy as a dependence in Tet2-deficient hematopoiesisPhase 1/2 trial of anti-CD7 allogeneic WU-CART-007 for patients with relapsed/refractory T-cell malignanciesA comprehensive genetic study of classic Hodgkin lymphoma using circulating tumor DNA
In this week's episode we'll learn about targeting NPM1 in acute myeloid leukemia. Researchers report the first clinical evidence of a menin inhibitor inducing complete remissions in AML with a NPM1 mutation. This validates NPM1 as a new therapeutic target in AML, alongside FLT3, IDH1/2, and KMT2A. Also on the podcast: targeting CD137 to prevent graft-versus-host disease. In nonhuman primates, a single dose of a CD137 antibody-drug conjugate provided long-term protection, with one important caveat: the potential for viral reactivation.Featured Articles: Menin inhibition with revumenib for NPM1-mutated relapsed or refractory acute myeloid leukemia: the AUGMENT-101 studyA single dose of a CD137 antibody–drug conjugate protects rhesus macaque allogeneic HCT recipients against acute GVHD
Blood Editor, Dr. Thomas Coates interviews Dr. Emanuele Angelucci on his paper, "How I manage iron overload in the hematopoietic cell transplantation setting" which is featured in Blood's "How I Treat Series on Iron Overload in Hematologic Disorders".

In this week's episode we'll learn about how by combining PET response with circulating tumor DNA, or ctDNA, in newly treated patients with follicular lymphoma, investigators identify those patients likely to progress within 24 months of initial treatment, also known as POD24. After that: Immune hotspots in aplastic anemia. These newly identified hotspots potentially represent sites in the bone marrow where the active immune response takes place, driving the destruction of hematopoietic stem and progenitor cells. Finally, allogeneic transplantation for Hodgkin lymphoma in the checkpoint inhibitor era. In a large, retrospective study, patients with prior checkpoint inhibitor exposure had remarkable outcomes, particularly when post-transplant cyclophosphamide was used.Featured Articles: Combined PET and ctDNA response as predictors of POD24 for follicular lymphoma after first-line induction treatmentImaging Mass Cytometry Reveals the Order of Events in the Pathogenesis of Immune-Mediated Aplastic AnemiaOutcomes of Allogeneic HCT in Hodgkin Lymphoma in the Era of Checkpoint Inhibitors: A Joint CIBMTR and EBMT Analysis

In this week's episode, we'll learn about a JAK inhibitor to prevent complications of CD19-directed CAR T-cell therapy. In a phase 2 study, itacitinib was well tolerated and demonstrated promising reductions in the incidence of cytokine release syndrome and neurotoxicity. After that: investigators report direct interactions between ChAdOx1 and platelets under arterial shear conditions. Investigators say it’s a novel biophysical mechanism that potentially contributes to post-vaccination arterial thrombosis. Finally, we explore lineage switch, an emerging form of acute leukemia relapse with dismal outcomes. It arises rapidly following antigen-targeted immunotherapy, highlighting the importance of advanced methods for detection and treatment.Featured Articles: Itacitinib for the prevention of IEC therapy–associated CRS: results from the 2-part phase 2 INCB 39110-211 studyShear-dependent platelet aggregation by ChAdOx1 nCoV-19 vaccine: a novel biophysical mechanism for arterial thrombosisProject EVOLVE: an international analysis of postimmunotherapy lineage switch, an emergent form of relapse in leukemia

1In this week's episode, we'll learn about rapid, high-sensitivity diagnostic assays for TTP, or thrombotic thrombocytopenic purpura, that can reduce unnecessary treatments. After that: enhancing PD-1 blockade in relapsed/refractory extranodal NK/T-cell lymphoma. In a single-arm, phase 2 study, combined CD38 and PD-1 inhibition demonstrated durable responses and manageable safety. Finally, a lymphoma horror story with a happy ending. CREBBP mutations create a zombie enzyme that competes with its wild-type counterparts. By enforcing CD40 signaling, a bispecific antibody overcomes this effect and induces lymphoma cell death.Featured Articles:Rapid ADAMTS13 activity assays for thrombotic thrombocytopenic purpura: a systematic review and meta-analysisEfficacy of combined CD38 and PD-1 inhibition with isatuximab and cemiplimab for relapsed/refractory NK/T-cell lymphomaBlunted CD40-responsive enhancer activation in CREBBP-mutant lymphomas can be restored by enforced CD4 T-cell engagement

In this week's episode, we'll learn about using AI to assess transplant risk in myelofibrosis. In a step toward personalized medicine, researchers report on a machine learning model that identifies 25% of patients with poor outcomes. After that: preventing priapism in men with sickle cell anemia. A recent phase 2 feasibility study shows high rates of recruitment, retention, and adherence to oral therapies, coupled with a significant reduction in the risk of this difficult complication. Finally, new research indicates that hallmarks of terminal T-cell exhaustion are absent in multiple myeloma, from diagnosis through maintenance therapy. We explore these provocative and counterintuitive findings arising from profiling of blood and marrow samples.Featured Articles:Use of machine learning techniques to predict poor survival after hematopoietic cell transplantation for myelofibrosisA controlled trial for preventing priapism in sickle cell anemia: hydroxyurea plus placebo vs hydroxyurea plus tadalafilHallmarks of T-cell exhaustion and antigen experience are absent in multiple myeloma from diagnosis to maintenance therapy
