Blood Podcast

In this week's episode we'll discuss HA-1-targeted T-cell receptor T-cell therapy for recurrent leukemia after hematopoietic stem cell transplantation. Next, we'll learn about how 4D intravital imaging in mice reveals the key role of platelets as a source of procoagulant membranes in hemostasis. Finally, we'll hear about modifications to a common induction and maintenance treatment for treatment-naïve mantle-cell lymphoma.Featured ArticlesHA-1–targeted T-cell receptor T-cell therapy for recurrent leukemia after hematopoietic stem celltransplantation4D intravital imaging studies identify platelets as the predominant cellular procoagulant surface in a mousehemostasis modelRandomized study of induction with bendamustine-rituximab ± bortezomib and maintenance withrituximab ± lenalidomide for MCL

Late relapses in younger patients with mantle cell lymphoma and what those outcomes look like. Mass spectrometry monitoring of M‑protein in peripheral blood during multiple myeloma maintenance. Experimental in vivo CAR T‑cell generation in nonhuman primates using lentiviral vectors targeting CD19.

Introduced by Associate Editor Dr. Thomas Ortel, this bonus episode discusses the Review Series on Factor XI, published in volume 143 issue 15 of Blood Journal. Dr. Ortel is joined by contributing authors Owen McCarty, PhD, Gili Kenet, MD, and David Gailani, MD.

In this week's episode we'll learn how cytomegalovirus infection early in life depletes preleukemic cells in a mouse model of B-cell acute lymphoblastic leukemia. After that we'll discuss new research, where GVHD targets organoid-forming bile duct stem cells in a TGF-beta-dependent manner. Conversely, a TGF-beta inhibitor protects these stem cells against GVHD and mitigates biliary dysfunction. Finally, we'll hear about the seven-year outcomes for venetoclax-ibrutinib in relapsed or refractory mantle cell lymphoma. In addition to long-term survival benefits, researchers report durable treatment-free remissions and effective retreatment in patients with MRD-negative complete responses.

In this week's episode we'll learn about iron, HFE hemochromatosis, and infections. In this large, population-based study, both high and low levels of plasma iron and transferrin saturation were associated with increased risks of infection. Then, we'll discuss how bispecific antibodies improve CAR T-cell response in B-cell malignancies. In-vitro and in-vivo data demonstrate enhanced therapeutic efficacy when a CD20-directed bispecific antibody is given in combination with CD19-directed CAR-T cells. Finally, we'll hear about determinants of outcome in NPM1-mutated AML. In a large series of patients with NPM1-mutated AML, investigators identified several variables beyond FLT3-ITD that adversely impacted outcomes.

In this week's episode we’ll discuss how immune fitness impacts response to teclistamab in relapsed/refractory multiple myeloma; learn more about a new mechanism of resistance to asciminib conferred by the BCR::ABL1 M244V mutation, and discuss the impact of hematopoietic cell transplantation on myocardial fibrosis in young patients with sickle cell disease.

In this week's episode we’ll discuss the safety and efficacy of decitabine in older patients with AML; learn how heme-induced loss of renovascular endothelial protein C receptor promotes chronic kidney disease in sickle mice, and discuss the outcomes of treatment with HLA-mismatched HSCT with TCRab/CD19 lymphocyte depletion or post-HSCT cyclophosphamide for inborn errors of immunity.

In this week's episode we'll discuss minimal residual disease as an intermediate clinical endpoint for multiple myeloma. Then, we'll learn about IPSS-R downstaging before transplant in MDS. Finally we'll hear about the connection between hereditary angioedema and venous thromboembolism. Featured Articles:EVIDENCE meta-analysis: evaluating minimal residual disease as an intermediate clinical endpoint for multiple myeloma Does IPSS-R down-staging before transplantation improve the prognosis of patients with Myelodysplastic Neoplasms? Increased risk of venous thromboembolism [or VTE] in young and middle-aged individuals with hereditary angioedema: a family study

In this week's episode we’ll discuss the safety and efficacy of acalabrutinib, venetoclax and obinutuzumab in relapsed/refractory CLL; learn more about alternative donor transplantation for severe aplastic anemia and discuss clonal relapse dynamics in acute myeloid leukemia following allogeneic hematopoietic cell transplantation.Featured Articles: Acalabrutinib, venetoclax and obinutuzumab in relapsed/refractory CLL: Final efficacy and ctDNA analysis of the CLL2-BAAG trial Alternative donor transplantation for severe aplastic anemia: a comparative study of the SAAWP EBMT Clonal relapse dynamics in acute myeloid leukemia following allogeneic hematopoietic cell transplantation 

In this week's episode we'll learn about the clinical benefit of complete remission with partial hematological recovery, or CRh, in patients with Acute Myeloid Leukemia (AML) treated with molecularly targeted drugs. Then we'll hear about a large cohort of patients with PNH were studied to detail PNH-related thrombotic events, unravel determinants of thrombosis, and evaluate anti-coagulation strategies. Finally, we'll see how new research shows that SOX11 expression is restricted to EBV-negative Burkitt lymphoma, and is associated with a specific genetic landscape. Featured Articles:Complete Remission with Partial Hematological Recovery as a Palliative Endpoint for Treatment of Acute Myeloid Leukemia Paroxysmal nocturnal hemoglobinuria-related thrombosis in the era of novel therapies: a 2043 patient/years analysis SOX11 expression is restricted to EBV-negative Burkitt lymphoma and associates with molecular genetic features
