Pre-treatment Pulmonary Function Testing Has Limited Utility In B-cell Lymphoma Treated with CD19 CAR T-cells.

Pulmonary function tests (PFT) are recommended for hematopoietic cell transplantation (HCT) evaluation. However, their prognostic value in chimeric antigen receptor T-cell (CAR-T) therapy remains unclear. We assessed the predictive significance of PFTs and pulmonary comorbidity classifications, per the Hematopoietic Cell Transplantation-Comorbidity Index (HCT-CI), in B-cell lymphoma patients undergoing autologous CD19-CAR-T therapy.

Point of care CD19 chimeric antigen receptor (CAR) T-cells for relapsed/refractory acute myeloid leukemia (AML) with aberrant CD19 antigen expression.

Relapsed/refractory (r/r) acute myeloid leukemia (AML) is associated with poor prognosis. CD19 is a B-cell marker, is aberrantly expressed in AML, mostly with t(8; 21)(q22; q22.1).

Liver stiffness measurements predict Sinusoidal Obstructive Syndrome after hematopoietic stem cell transplantation.

Sinusoidal Obstructive Syndrome (SOS) is a life-threatening complication after hematopoietic stem-cell transplantation (HSCT), characterized by post-sinusoidal portal hypertension. FibroScan is used to assess portal hypertension non-invasively. We assessed transient elastography (TE) applicability in diagnosing SOS.

Fecal microbiota transplantation in capsules for the treatment of steroid refractory and steroid dependent acute graft vs. host disease: a pilot study.

Acute graft-versus-host disease (aGvHD) is a serious complication of allogeneic hematopoietic stem-cell transplantation with limited treatment options. The gut microbiome plays a critical role in aGvHD pathogenesis. Fecal microbiota transplantation (FMT) has emerged as a potential therapeutic approach to restore gut microbial diversity.

Point-of-care anti-CD19 chimeric antigen receptor T-cell therapy for relapsed/refractory follicular lymphoma.

Patients with relapsed/refractory follicular lymphoma (R/R-FL) often require multiple treatment lines. We performed a phase 1b/2 single-center clinical trial of autologous point-of-care anti-CD19 chimeric antigen receptor (CAR) T-cells in R/R-FL patients treated patients with ≥ 2 treatment lines. All 26 patients enrolled received CAR T-cell infusion at a median of 11 days after leukapheresis.

Second hematopoietic stem cell transplantation as salvage therapy for relapsed acute myeloid leukemia/myelodysplastic syndromes after a first transplantation.

Second allogeneic hematopoietic stem-cell transplantation (HSCT2) is a therapeutic option for patients with acute myeloid leukemia (AML)/myelodysplastic syndrome (MDS) relapsing after a first transplant (HSCT1). However, patients allocated to HSCT2 may be a selected group with better prognosis and the added efficacy of HSCT2 is not well established. We retrospectively analyzed 407 consecutive patients with relapsed AML/MDS after HSCT1.

Allogeneic Hematopoietic Cell Transplantation after Chimeric Antigen Receptor T Cell Therapy in Large B Cell Lymphoma.

Anti-CD19 chimeric antigen receptor T cell (CAR-T) therapy has transformed the care of patients with relapsed/refractory large B cell lymphoma (LBCL). However, approximately 60% of CAR-T recipients ultimately will experience disease recurrence or progression. Salvage therapies after CAR-T treatment failures are of limited efficacy and have a short duration of response.

Outcomes of first therapy after CD19-CAR-T treatment failure in large B-cell lymphoma.

Persistence or recurrence of large B-cell lymphoma after CD19-CAR-T is common, yet data guiding management are limited. We describe outcomes and features following CAR-T treatment failure. Of 305 adults who received CD19-CAR-T, 182 experienced disease recurrence or progression (1-year cumulative incidence 63% [95%CI: 57-69]).

Point-of-care CAR T-cell therapy as salvage strategy for out-of-specification tisagenlecleucel.

Tisagenlecleucel (tisa-cel) is an anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved for patients with relapsed/refractory large B-cell lymphoma. Outcomes of patients with out-of-commercial specification (OOS) CAR T products are not well characterized. We therefore assessed 37 adult patients who underwent leukapheresis for tisa-cel therapy in a single center.

Point-of-care anti-CD19 CAR T-cells for treatment of relapsed and refractory aggressive B-cell lymphoma.

Anti CD19 chimeric antigen receptor (CAR) T-cell therapy has transformed the care of relapsed and refractory aggressive B-cell lymphoma. However, financial toxicity and manufacturing time represent barriers to its widespread implementation. Study applicability, toxicity, and efficacy of a locally produced autologous CD19-directed CAR T-cell product were studied.

Immunogenicity and safety of the BNT162b2 mRNA COVID-19 vaccine in haematopoietic stem cell transplantation recipients.

The immunogenicity and safety of Pfizer-BioNTech BNT162b2 mRNA vaccine in allogeneic haematopoietic stem cell transplantation (HSCT) recipients are unknown. We prospectively followed 152 HSCT recipients who were at least six months following transplantation and with no active acute graft-versus-host disease (GVHD). Blood samples were taken 2-4 weeks after the second vaccination and analyzed for receptor-binding domain (RBD) antibodies and neutralizing antibodies (NA).

BNT162b2 mRNA COVID-19 vaccination in immunocompromised patients: A prospective cohort study.

Background: Trials of the Pfizer-BioNTech BNT162b2 mRNA vaccine showed 95% efficacy in preventing symptomatic disease; however, the trials excluded immunocompromised patients (ICPs). We aim at analyzing antibody response in ICPs.

Methods: A prospective cohort study was conducted at Sheba Medical Center, Israel, between January and April 2020, in 1274 participants who received the vaccine, including 1002 ICPs and 272 immunocompetent healthcare workers (HCWs).

Long-acting granulocyte colony-stimulating factor pegfilgrastim (lipegfilgrastim) for stem cell mobilization in multiple myeloma patients undergoing autologous stem cell transplantation.

Autologous stem cell transplantation (ASCT) is a standard of care in newly-diagnosed multiple myeloma (MM) patients. Several studies before the introduction of novel therapies in MM, demonstrated a pegylated G-CSF to be successful in mobilizing peripheral blood stem cells (PBSCs). Lipegfilgrastim is a novel long-acting G-CSF that is produced by the conjugation of a single 20-kDa polyethelene glycol to the natural O-glycosylation site of G-CSF.

High lactate dehydrogenase at time of admission for allogeneic hematopoietic transplantation associates to poor survival in acute myeloid leukemia and non-Hodgkin lymphoma.

Risk stratification is important for balancing potential risks and benefits of allogeneic hematopoietic stem cell transplantation (HSCT) for hematological malignancies. We retrospectively studied 1119 patients undergoing allogenic-HSCT in a single center for five hematological indications assessing the prognostic role of LDH at admission for survival (OS), progression-free survival (PFS), relapse incidence (RI), and nonrelapse mortality (NRM). In non-Hodgkin lymphoma (NHL) and acute myeloid leukemia (AML), higher than median LDH had an adverse effect on survival.

Complete Remission with Incomplete Blood Count Recovery Is a Strong Predictor of Nonrelapse Mortality in Acute Myeloid Leukemia Patients Undergoing Allogeneic Stem Cell Transplantation.

Introduction: Achievement of an initial complete remission (CR) following induction chemotherapy is tightly correlated with survival in acute myeloid leukemia (AML) patients, yet patients in CR with incomplete hematologic recovery (CRi) still experience improved outcomes compared with nonresponding patients. Whether CRi predicts prognosis in patients referred to an allogeneic stem cell transplantation (allo-SCT) is incompletely defined. In this analysis, we evaluated whether clinical outcomes of transplanted AML patients in CR and CRi were significantly different.

Immune imitation of tumor progression after anti-CD19 chimeric antigen receptor T cells treatment in aggressive B-cell lymphoma.

We present three patients with aggressive non-Hodgkin's B-cell lymphoma (NHL) who received anti-CD19 chimeric antigen receptor T (CAR T) cells therapy after failure of several lines of chemotherapy that developed pseudo-progression. One-week clinical and radiological findings were consistent with tumor progression. Positron emission tomography-computed tomography (PET-CT) at 1 month post CAR T cells administration was consistent with treatment response.

Carfilzomib combined with cyclosporine and methotrexate for the prevention of graft-versus-host disease after allogeneic stem-cell transplantation from unrelated donors.

Acute graft-versus-host disease (aGVHD) is the major treatment-related complication after stem-cell transplantation (SCT) from unrelated donors. The proteasome-inhibitor bortezomib was added to GVHD prevention regimens with initial promise. However, two randomized studies failed to show efficacy.

Reassessing the role of high dose cytarabine and mitoxantrone in relapsed/refractory acute myeloid leukemia.

A substantial segment of patients with acute myeloid leukemia (AML) will relapse following an initial response to induction therapy or will prove to be primary refractory. High-dose cytarabine and mitoxantrone (HiDAC/MITO) is an established salvage therapy for these patients. We studied all adult patients with relapsed/refractory (R/R) AML who were treated with HiDAC/MITO in our center between the years 2008-2017.

LDH and renal function are prognostic factors for long-term outcomes of multiple myeloma patients undergoing allogeneic hematopoietic stem cell transplantation.

Allogeneic hematopoietic stem cell transplantation (allo-SCT) may offer a cure for selected patients with multiple myeloma (MM). Effective prognostic markers to guide patient selection are warranted. We retrospectively studied a cohort of 100 relapsed refractory MM patients who underwent allo-SCT.

Allogeneic hematopoietic stem cell transplantation with fludarabine, busulfan, and thiotepa conditioning is associated with favorable outcomes in myelofibrosis.

Allogeneic stem cell transplantation is a curative therapy for myelofibrosis. The optimal conditioning regimen has not been well defined. We retrospectively compared transplantation outcomes in patients with myelofibrosis (n = 67) conditioned with myeloablative (MAC, 36%) and reduced-intensity (RIC, 46%) regimens, and more recently with the combination of thiotepa, busulfan, and fludarabine (TBF, 18%).

Haploidentical vs. unrelated allogeneic stem cell transplantation for acute lymphoblastic leukemia in first complete remission: on behalf of the ALWP of the EBMT.

Unmanipulated haploidentical allogeneic stem cell transplantation (Allo-SCT) has become an attractive alternative for patients lacking HLA-matched sibling or unrelated donors. However, data of outcome in ALL is still scarce. The outcomes of 1234 adult patients with ALL in first complete remission (CR1) who underwent Allo-SCT between 2007 and 2016 were analyzed.

Risk factors and implications of oral mucositis in recipients of allogeneic hematopoietic stem cell transplantation.

Background: Oral mucositis (OM) is a common toxicity of stem cell transplantation (SCT). We sought to evaluate OM burden, risk factors, and implications in a cohort of allogeneic-SCT recipients.

Methods: This was a single-center study including 115 adult allogeneic-SCT transplanted between 2016 and 2018 for various hematological conditions.
