The Genotype of the Donor for the (GT)n Polymorphism in the Promoter/Enhancer of FOXP3 Is Associated with the Development of Severe Acute GVHD but Does Not Affect the GVL Effect after Myeloablative HLA-Identical Allogeneic Stem Cell Transplantation.
The FOXP3 gene encodes for a protein (Foxp3) involved in the development and functional activity of regulatory T cells (CD4+/CD25+/Foxp3+), which exert regulatory and suppressive roles over the immune system. After allogeneic stem cell transplantation, regulatory T cells are known to mitigate graft versus host disease while probably maintaining a graft versus leukemia effect. Short alleles (<=(GT)(15)) for the (GT)(n) polymorphism in the promoter/enhancer of FOXP3 are associated with a higher expression of FOXP3, and hypothetically with an increase of regulatory T cell activity. This polymorphism has been related to the development of auto-or alloimmune conditions including type 1 diabetes …
Real-World Evidence of Tisagenlecleucel for the Treatment of Relapsed or Refractory Large B-Cell Lymphoma
Introduction Tisagenlecleucel (tisa-cel) is a second generation, CD19-targeted Chimeric Antigen Receptor (CAR) T-cell therapy for relapsed or refractory (R/R) large B-cell lymphoma (LBCL). The pivotal phase 2 trial JULIET included 93 patients and reported an overall response rate (ORR) of 52% and a complete response rate of 40% among treated patients. However, very little is known regarding its safety and efficacy in the commercial or real-world setting as well as from an intention-to-treat perspective. In our study, we report clinical outcomes of patients with R/R LBCL treated with commercial tisa-cel in 10 Spanish institutions. Methods Data were collected retrospectively from all consecut…

Single umbilical cord blood with or without CD34+ cells from a third-party donor in adults with leukemia
We retrospectively compared the clinical outcomes of adults with acute leukemia who received single-unit umbilical cord blood (UCB) transplantation (sUCBT) (n = 135) or stem cell transplant using coinfusion of a UCB graft with CD34+ cells from a third-party donor (Haplo-Cord) (n = 72) at different institutions within the Grupo Espanol de Trasplante Hematopoyetico. In multivariable analysis, patients in the Haplo-Cord group showed more rapid neutrophil (hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.5-3.3; P < .001) and platelet recovery (HR, 1.6; 95% CI, 1.2-2.3; P = .015) and lower incidence of chronic graft-versus-host disease (GVHD) (relative risk, 0.5; 95% CI, 0.3-0.8; P = .01)…
Post-transplantation cyclophosphamide after HLA identical compared to haploidentical donor transplant in acute myeloid leukemia: a study on behalf of GETH-TC
Post-transplantation cyclophosphamide (PTCY) effectively prevents graft-versus-host disease (GVHD) after unmanipulated HLA-haploidentical hematopoietic stem cell transplantation (HSCT) and achieves low rates of GVHD in HLA-identical transplantation. To compare the outcomes of haploidentical versus HLA identical HSCT in patients undergoing HSCT for acute myeloid leukemia (AML) using PTCY. We conducted a retrospective study of 229 patients undergoing first HSCT for AML using PTCY with additional immunosuppression, 99 from matched sibling or unrelated donor (MSD/MUD) performed in 3 hospitals and 130 from haploidentical donors (haplo group) performed in 20 hospitals within the Spanish Group of …
Hospital and outpatient models for Hematopoietic Stem Cell Transplantation: A systematic review of comparative studies for health outcomes, experience of care and costs.
The number of Hematopoietic Stem Cell Transplantations has risen in the past 20 years. The practice of outpatient Hematopoietic Stem Cell Transplantation programs is increasing in an attempt to improve the quality of patient care and reduce the demand for hospital admission. A systematic review of 29 comparative studies between in-hospital and outpatient treatment of Hematopoietic Stem Cell Transplantation, with no restriction by outpatient regime was conducted. This study aims to analyse the current evidence on the effects of the outpatient model on patient-centred outcomes, comparing both in-hospital and outpatient models for autologous and allogeneic HSCT using the Triple Aim framework: …
Real‐world evidence of tisagenlecleucel for the treatment of relapsed or refractory large B‐cell lymphoma
Abstract Tisagenlecleucel (tisa‐cel) is a second‐generation autologous CD19‐targeted chimeric antigen receptor (CAR) T‐cell therapy approved for relapsed/refractory (R/R) large B‐cell lymphoma (LBCL). The approval was based on the results of phase II JULIET trial, with a best overall response rate (ORR) and complete response (CR) rate in infused patients of 52% and 40%, respectively. We report outcomes with tisa‐cel in the standard‐of‐care (SOC) setting for R/R LBCL. Data from all patients with R/R LBCL who underwent leukapheresis from December 2018 until June 2020 with the intent to receive SOC tisa‐cel were retrospectively collected at 10 Spanish institutions. Toxicities were graded accor…
