Allogeneic stem cell transplantation for patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) has been performed primarily an HLA-matched donor. Outcomes of haploidentical have recently improved, a comparison between donor sources in uniform cohort not performed. We evaluated outcomes 227 AML/MDS treated melphalan-based conditioning. Donors were matched related (MRD) (n = 87, 38%), unrelated (MUD) 108, 48%), or 32, 14%). No significant differences found MUD...

Abstract The impact of bridging therapy (BT) administered between leukapheresis and chimeric antigen receptor (CAR) T-cell for large B-cell lymphoma (LBCL) is unclear. We evaluated the influence BT (systemic [ST], radiation [RT], or combined-modality [CMT]) on outcomes 148 LBCL patients who underwent planned axicabtagene ciloleucel (axi-cel) infusion. 55% (n = 81) received were more likely to have international prognostic index (IPI) score ≥3 (P ≤ .01), bulky disease elevated lactate...

Multiple myeloma (MM) is a disease with known immune dysregulation. Natural killer (NK) cells have shown preclinical activity in MM. We conducted first-in-human study of umbilical cord blood-derived (CB) NK for MM patients undergoing high dose chemotherapy and autologous haematopoietic stem cell transplantation (auto-HCT). Patients received lenalidomide (10 mg) on days −8 to −2, melphalan 200 mg/m2 day −7, CB-NK −5 auto-HCT 0. Twelve were enrolled, three each four levels: 5 × 106, 1 107, 107...

T cell-mediated hyperinflammatory responses, such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity (ICANS), are now well-established toxicities of chimeric antigen receptor (CAR) cell therapy. As the field CAR cells advances, however, there is increasing recognition that hemophagocytic lymphohistiocytosis (HLH)-like following infusion occurring broadly across patient populations constructs. Importantly, these HLH-like often not directly associated with CRS...

JC virus, the cause of progressive multifocal leukoencephalopathy (PML), and BK virus are genetically similar share sequence homology in immunogenic proteins. We treated three immunosuppressed patients with PML ex vivo-expanded, partially HLA-matched, third-party-produced, cryopreserved virus-specific T cells. The immunosuppression these was due to conditioning regimen for cord-blood transplantation one patient, a myeloproliferative neoplasm ruxolitinib another, acquired immunodeficiency...

Chimeric antigen receptor (CAR) T-cell therapy targeting CD19 may be associated with long-term adverse effects such as cytopenia and immune deficiency. In order to characterize these late events, we analyzed 31 patients relapsed or refractory large B-cell lymphoma treated axicabtagene ciloleucel at our institution on two clinical trials, ZUMA-1 (clinicaltrials gov. Identifier: NCT02348216) ZUMA-9 NCT03153462). Complete blood counts, lymphocyte subsets, immunoglobulin levels were measured...

Neurotoxicity or immune effector cell-associated neurotoxicity syndrome (ICANS) is the second most common acute toxicity after chimeric antigen receptor (CAR) T-cell therapy. However, there are limited data on clinical and radiologic correlates of ICANS. We conducted a cohort analysis 100 consecutive patients with relapsed refractory large B-cell lymphoma (LBCL) treated standard care axicabtagene ciloleucel (axi-cel). ICANS was graded according to an objective grading system. Neuroimaging...
