In "Immune thrombocytopenia in patients treated with immune checkpoint inhibitors" Dr. Leaf and colleagues define the incidence, clinical features, and outcomes of ICI-induced immune thrombocytopenia. Showing that ICI-induced immune thrombocytopenia is associated with excess mortality, these data should provide an impetus to greater recognition and to protocolization of effective interventions.

Hepcidin-DMT1 interaction and GPRC5D-targeting bispecific antibody for MM

American Society of Hematology — Thu, 12 Mar 2026 12:00:00 -0400

In this week's episode, Blood editor Dr. Laura Michaelis interviews authors Drs. Marion Falabrègue and Ajai Chari on their papers published in volume 146 issue 24 of Blood. The work of Dr. Falabrègue and colleagues in "Intestinal hepcidin overexpression promotes iron deficiency anemia and counteracts iron overload via DMT1 downregulation" indicates that iron absorption from the apical surface of enterocytes can be modulated through manipulation of the hepcidin-DMT1 interaction, opening new avenues for research and therapeutic manipulation. "Talquetamab plus daratumumab in multiple myeloma" features a phase 1b/2 trial of 65 heavily pretreated patients with MM, where Chari et al combined daratumumab and talquetamab, a GPRC5D-targeting bispecific antibody, reporting depletion of CD38-expressing regulatory T cells following daratumumab and impressive efficacy, with an 80% overall (57% complete) response rate and median progression-free survival of 23.3 months. This regimen is now being evaluated in a phase 3 trial.

PETAL Consortium Survival Prognosticators and How Inflammation Impacts Hematopoiesis

American Society of Hematology — Thu, 05 Mar 2026 12:00:00 -0500

In this week's episode, Blood associate editor Dr. Laura Michaelis interviews Drs. Mark Sorial and Emmanuelle Passegue on their articles published in volume 147 issue 7 of Blood. Dr. Sorial discusses "Early time to relapse as a survival prognosticator in nodal mature T-cell lymphomas: results from the PETAL consortium" where he and his team evaluated the prognostic significance of early relapse in a large retrospective cohort. They report a time to relapse of <12 months as a strong predictive factor independent of the prognostic index for T-cell lymphoma and histology, with results validated in 2 independent cohorts. Dr. Emmanuelle Passegue discusses "Inflammation perturbs hematopoiesis by remodeling specific compartments of the bone marrow niche". Using a combination of single-cell RNA sequencing profiling and flow cytometry, the team characterized the bone marrow niche compartments in mice subjected to inflammation. They show that inter-feron-mediated inflammation preferentially targets central marrow leptin receptor–expressing mesenchymal cells, triggering cytokine release that affects monocyte dynamics in the bone marrow microenvironment.

VTE Recurrence Risk Factors and poor-response AML Transplant Outcome Indicators

American Society of Hematology — Thu, 01 Jan 2026 12:00:00 -0500

In this week's episode we've pulled a vault recording from 2025! Blood editor Dr. Laurie Sehn interviews authors Drs. David-Alexandre Trégouët and Johannes Schetelig on their research published in volume 146 issue 19 of Blood journal. Dr. Trégouët's study conducted a genome-wide association study supplemented by transcriptome and Mendelian randomization analyses to identify 28 loci and proteins associated with VTE recurrence risk. This work provides genomic evidence that inherited variants contribute to the risk of VTE recurrence, raising the possibility of a more personalized approach to the prevention of recurrent VTE. The study conducted by Dr. Schetelig and colleagues report the results of a long term trial on patients with poor-response AML, comparing outcomes between patients who received salvage chemotherapy versus immediate transplantation. With no difference in survival rates at 5 years, outcomes seem to be determined mainly by genetic risk factors, age, and comorbidities, therefore challenging the routine use of intensive remission induction before allogeneic transplant in patients with an available donor and underscore the need for novel therapeutic strategies for poor-risk AML.

Early prediction of follicular lymphoma patients with poor survival; immune hotspots in aplastic anemia; role of allo-transplant for Hodgkin lymphoma in the checkpoint inhibitor era

American Society of Hematology — Thu, 21 Aug 2025 12:00:00 -0400

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.

Special Episode: Eliminating the Need for Sequential Confirmation of Response in Multiple Myeloma

American Society of Hematology — Tue, 10 Jun 2025 08:00:00 -0400

In this special episode, Dr. Shaji Kumar from the Mayo Clinic speaks with Blood editor Dr. Laurie Sehn on a paper recently published in Blood, "Eliminating the Need for Sequential Confirmation of Response in Multiple Myeloma". The findings demonstrate eliminating the need for sequential confirmation of response in multiple myeloma. The study, involving 583 episodes of progression, found that simultaneous confirmation of disease progression using two different markers (e.g., serum protein electrophoresis and serum free light chain assay) was 98% accurate, compared to 82% for sequential confirmation. This suggests that simultaneous confirmation could improve clinical trial accuracy and reduce false censoring. The International Myeloma Working Group is set to revise its response criteria to incorporate these findings, potentially simplifying disease assessment and reducing the need for multiple blood draws.

American Society of Hematology — Thu, 29 May 2025 12:00:00 -0400

In this week's episode, we'll hear about new insights into PU.1-mutated agammaglobulinemia. Researchers show that haploinsufficiency of the master transcriptional regulator PU.1 causes agammaglobulinemia and dendritic cell deficiencies. These patients experience an array of infectious and non-infectious complications, but not leukemia. After that: venetoclax-based induction therapy in younger patients with AML. Venetoclax plus decitabine was associated with superior safety and non-inferior response rates compared to intensive chemotherapy. Is it time to consider lower-intensity therapy beyond older and unfit patients? Finally, a focus on venous thromboembolism. Researchers link BGAT, an enzyme pivotal to determining blood type, to risk of future VTE. They say high plasma levels of BGAT contribute to risk above and beyond what can be explained by von Willebrand factor and Factor VIII.

Discontinuing lenalidomide maintenance in MM; congenital neutropenia syndrome linked to COPZ1 mutations; low GVHD rates with ruxolitinib after allogeneic HCT

American Society of Hematology — Thu, 15 May 2025 12:17:31 -0400

In this week's episode, we'll learn about stopping myeloma maintenance therapy in the modern era. New research suggests that many patients in remission can discontinue lenalidomide, remaining treatment-free, without jeopardizing disease response. After that: a novel congenital neutropenia syndrome. Mutations in the COPZ1 gene impact myeloid differentiation and development of neutropenia. Researchers describe the mechanisms and propose a treatment strategy for restoring granulopoiesis. Finally, ruxolitinib maintenance therapy after allogeneic transplant. In a phase 2 study, this treatment strategy was associated with low rates of chronic graft-versus-host disease. Investigators say the use of JAK inhibitors in this context warrants further study.

The decline of transplant for relapsed myeloma; DDAVP response in bleeding disorders; dual DOT1L/EZH2 targeting in DLBCL

American Society of Hematology — Thu, 17 Apr 2025 12:00:00 -0400

In this week's episode we'll learn about the role of autologous transplant for relapsed myeloma. In an updated analysis of the GMMG ReLApsE trial, salvage autologous transplant offered no survival benefit compared to control chemotherapy. These findings may have clinical implications in an era of alternative, and highly effective, treatment options. After that: Response to DDAVP, or desmopressin, in bleeding disorders. This study is the first large scale meta-analysis to assess the response rate to DDAVP in bleeding disorders. Authors provide new insights into determinants of response, which vary according to the disease type. Finally, turning to diffuse large B cell lymphoma. Germinal center B cells depend on the activity of DOT1 and EZH2 to maintain their pro-proliferative identity. New research shows that combined treatment with DOT1L and EZH2 inhibitors has synergistic activity in vitro.

Mutations in AMBRA1 aggravate β-thalassemia; targeting MYD88 mutations in lymphomas; air pollution and incident VTE risk

American Society of Hematology — Thu, 06 Mar 2025 12:00:00 -0500

In this week's podcast, a potential new therapeutic target in beta-thalassemia. The E3 ubiquitin ligase AMBRA1 promotes autophagic clearance of free alpha-globin. Researchers describe mutations in the AMBRA1 gene that impair this clearance, exacerbating ineffective erythropoiesis and disease severity. After that: targeting MYD88 mutations. Lasalocid-A is a compound that selectively binds to the MYD88 L265P mutant protein, which is found in a range of B-cell lymphomas. New research shows its potential to inhibit tumor growth, overcome ibrutinib resistance, and synergize with venetoclax. Finally: air pollution is linked to an increased risk of venous thromboembolism in a prospective, community-based cohort study. The findings highlight the harms of pollution, and support the case for global efforts to improve public health.
