Idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel (cilta-cel) have revolutionized the treatment of relapsed/refractory multiple myeloma (RRMM), but direct comparisons are lacking. Leveraging an international multicenter RRMM cohort, we compared the outcome of ide-cel ( = 162) versus cilta-cel ( = 42). Co-primary efficacy endpoints of the study were overall response rate (ORR) and progression-free survival (PFS).

Background: Allogeneic hematopoietic stem-cell transplantation is the only curative treatment for myelofibrosis. Driver mutations are the pathophysiological hallmark of the disease, but the role of mutation clearance after transplantation is unclear.

Methods: We used highly sensitive polymerase-chain-reaction technology to analyze the dynamics of driver mutations in peripheral-blood samples from 324 patients with myelofibrosis (73% with mutations, 23% with mutations, and 4% with mutations) who were undergoing transplantation after reduced-intensity conditioning.

Background: CAR-T cell (chimeric antigen receptor T) therapy is now part of standard of care treatment of B‑cell lineage malignancies. Although it is an effective treatment, it comes along with adverse side effects and toxicities that may require intensive care therapy. The costs related to critical care therapy in critically ill patients after CAR‑T administration have not been evaluated.

We investigated the effect of center-specific variables on overall survival (OS) after allogeneic hematopoietic cell transplantation (alloHCT) in acute myeloid leukemia (AML). Eligible were adult patients reported to DRST registry receiving first alloHCT for AML from a related or matched (>= 9/10 HLA-match) unrelated donor 2015-2021. Primary endpoint was OS at 12 months from alloHCT.

Article Synopsis
  • CAR T-cell therapy shows strong initial results for treating relapsed refractory multiple myeloma, but most patients eventually relapse, often within 5 months.
  • In a study of 139 patients who relapsed after CAR T-cell therapy, different salvage therapies were analyzed, revealing that bispecific antibodies, like talquetamab and teclistamab, had the best overall and complete response rates.
  • The presence of extramedullary disease at relapse was linked to poorer outcomes, but bispecific antibodies improved survival rates, suggesting they should be the standard treatment for patients relapsing after CAR T-cell therapy.

Despite the development of targeted therapies in first-line AML, complete remissions (CR) cannot be achieved in 30-40%, and relapse rates remain high. In R/R AML the intensive treatment regimen of fludarabine, cytarabine, idarubicin combined with venetoclax (FLA-VIDA) showed improved remission rates compared to FLA-IDA. In this retrospective single-center analysis, we investigated the efficacy and safety of dose-reduced FLA-IDA with and without venetoclax to minimize the risk of infectious complications and excessive myelosuppression; Methods: Between 2011 and 2023, 89 R/R AML patients were treated with dose-reduced FLA-IDA (fludarabine 30 mg/m day 1-4, cytarabine 2000 mg/m day 1-4, idarubicin 10 mg/m day 1 + 4).

Despite the introduction of JAK inhibitors, allogeneic hematopoietic cell transplant remains the only potentially curative treatment for patients with myelofibrosis but has considerable treatment-related complications. Whether the incorporation of JAK inhibition into the transplant algorithm leads to improved outcomes is still unclear. Here, we analyzed different transplant platforms in myelofibrosis patients undergoing a first transplant, comparing immune profiles and outcomes of (1) 33 patients continuing JAK inhibition at start of conditioning until stable engraftment (PERI-group), (2) 38 patients receiving JAK inhibition prior to transplant until start of conditioning (PRE-group), and (3) 38 patients that had never received JAK inhibition (NON-group).

  • - This study examined the effectiveness of three different conditioning regimens (Thiotepa-Busulfan, Sequential FLAMSA-Busulfan Fludarabine, and Treosulfan-Fludarabine) prior to allogeneic stem cell transplantation (allo-SCT) in patients with Chronic myelomonocytic leukemia (CMML) from 2006 to 2022.
  • - A total of 69 CMML patients participated, with notable variations in donor type and anti-T lymphocyte Globulin use for GVHD prophylaxis across groups.
  • - Results suggested that the Thiotepa-Busulfan group experienced better 3-year overall survival (OS) rates (80%) and progression-free survival (

Article Synopsis
  • The optimal TBI dose for patients with high-risk acute lymphoblastic leukemia (ALL) undergoing allogeneic stem cell transplantation (SCT) is still uncertain.
  • A retrospective analysis compared outcomes of patients treated with 8 Gy and 12 Gy total body irradiation (TBI) along with fludarabine and PTCy, revealing that while both doses show similar overall and leukemia-free survival, the 12 Gy dose offers better outcomes for MRD-positive patients.
  • The study suggests that the 8 Gy TBI results in lower non-relapse mortality but a higher relapse rate compared to 12 Gy, highlighting the need for further research to confirm these results with larger MRD patient groups.

  • Patients with JAGN1 mutations experience severe congenital neutropenia, leading to high rates of bacterial infections and poor response to G-CSF therapy.
  • Two unrelated patients, one pregnant and one an infant, received GM-CSF after G-CSF failure, but neither showed an increase in neutrophil counts and treatment was eventually stopped due to further declines and infections.
  • Despite the promising results in a mouse model, GM-CSF therapy did not benefit the patients, highlighting the need for early evaluation for hematopoietic stem cell transplantation in these cases.

Acute graft-versus-host disease (GVHD) is a significant complication following hematopoietic stem cell transplantation (HCT). Although recent advancements in GVHD prophylaxis have resulted in successful HCT across HLA barriers and expanded access to HCT for racial minorities, less is known about how race affects the severity and outcomes of acute GVHD. This study examines differences in the clinical course of acute GVHD and the prognostic value of GVHD biomarkers for Black and White recipients.

Improved long-term survival rates after allogeneic hematopoietic cell transplantation (alloHCT) make family planning for young adult cancer survivors an important topic. However, treatment-related infertility risk poses challenges. To assess pregnancy and birth rates in a contemporary cohort, we conducted a national multicenter study using data from the German Transplant Registry, focusing on adult women aged 18 to 40 years who underwent alloHCT between 2003 and 2018.

Acute graft-versus-host disease (GVHD) grading systems that use only clinical symptoms at treatment initiation such as the Minnesota risk identify standard and high-risk categories but lack a low-risk category suitable to minimize immunosuppressive strategies. We developed a new grading system that includes a low-risk stratum based on clinical symptoms alone and determined whether the incorporation of biomarkers would improve the model's prognostic accuracy. We randomly divided 1863 patients in the Mount Sinai Acute GVHD International Consortium (MAGIC) who were treated for GVHD into training and validation cohorts.

Although most patients with chronic graft-versus-host disease (cGVHD) show initial response to first-line therapy, long-term clinically meaningful success of first-line treatment remains rare. In a prospective multicentre phase II trial in 6 German centers, patients with newly diagnosed moderate or severe cGVHD received prednisone and everolimus for 12 months followed by a 1-year follow-up period. Primary endpoint was treatment success (TS) at 6 months defined as patient being alive, achieving PR or CR of cGVHD, having no relapse of underlying disease and requiring no secondary treatment for cGVHD.

The significance of biomarkers in second-line treatment for acute graft-versus-host disease (GVHD) has not been well characterized. We analyzed clinical data and serum samples at the initiation of second-line systemic treatment of acute GVHD from 167 patients from 17 centers of the Mount Sinai Acute GVHD International Consortium (MAGIC) between 2016 and 2021. Sixty-two patients received ruxolitinib-based therapy, whereas 102 received other systemic agents.

Graft-versus-host disease (GVHD) is a major cause of nonrelapse mortality (NRM) after allogeneic hematopoietic cell transplantation. Algorithms containing either the gastrointestinal (GI) GVHD biomarker amphiregulin (AREG) or a combination of 2 GI GVHD biomarkers (suppressor of tumorigenicity-2 [ST2] + regenerating family member 3 alpha [REG3α]) when measured at GVHD diagnosis are validated predictors of NRM risk but have never been assessed in the same patients using identical statistical methods. We measured the serum concentrations of ST2, REG3α, and AREG by enzyme-linked immunosorbent assay at the time of GVHD diagnosis in 715 patients divided by the date of transplantation into training (2004-2015) and validation (2015-2017) cohorts.

Background: Progressive multiple sclerosis (MS) is characterized by compartmentalized smoldering neuroinflammation caused by the proliferation of immune cells residing in the central nervous system (CNS), including B cells. Although inflammatory activity can be prevented by immunomodulatory therapies during early disease, such therapies typically fail to halt disease progression. CD19 chimeric antigen receptor (CAR)-T cell therapies have revolutionized the field of hematologic malignancies.

Article Synopsis
  • Acute graft versus host disease (GVHD) is a significant complication for children undergoing hematopoietic cell transplantation (HCT), and new tools have been developed to assess the risk of nonrelapse mortality (NRM) at the onset of treatment.
  • The study compared the Minnesota risk system and the MAGIC algorithm using biomarkers ST2 and REG3α, finding that MAGIC's probabilities (MAPs) were more effective in predicting outcomes in pediatric patients compared to Minnesota risk alone.
  • A combined model using both Minnesota risk and biomarker scores increased prediction accuracy further, demonstrating the potential for more personalized treatment approaches for children with GVHD.
