Transplantation and Cellular Therapy Meetings

Idecabtagene vicleucel demonstrated a statistically significant and clinically meaningful improvement in progression-free survival and objective response compared with standard of care approaches in patients with triple-class-exposed relapsed/refractory multiple myeloma.

Patients with multiple myeloma who were treated with autologous stem cell transplantation were found to be utilizing chronic opioids at high rates, in turn leading to worse overall survival outcomes at 6 months of follow-up.

Treatment with the cellular therapy Orca-T produced an improved graft-vs-host-disease and relapse-free survival rate in patients with high-risk myelodysplastic syndrome or acute leukemias.

Yago L. Nieto, MD, PhD, professor, Department of Stem Cell Transplantation and Cellular Therapy, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, discusses findings from a phase 2 trial investigating panobinostat (Farydak), gemcitabine, busulfan, and melphalan plus autologous stem cell transplant (ASCT) in patients with high-risk or relapsed/refractory multiple myeloma.

Samer A. Srour, MB ChB, MS, discusses findings with Orca-Q, an investigational therapy consisting of enriched CD34+ stem cells plus T-cell subsets, in patients with high-risk hematologic malignancies eligible for myeloablative conditioning and allogeneic stem cell transplant.

Because of an economic burden on the healthcare system occurring through the per-patient cost of allogeneic hematopoietic cell transplant, novel treatments to replace transplant and prevent graft-vs-host disease are necessary.

The presence of cytopenias did not affect the favorable and durable responses seen with ruxolitinib vs best available therapy in patients with steroid-refractory acute graft-vs-host disease.

Early treatment with ruxolitinib led to high response rates in patients with steroid refractory acute graft-vs-host-disease, although benefits with ruxolitinib vs best available therapy were observed regardless of the timing of ruxolitinib administration.

A study did not find a correlation between the pharmacokinetics and pharmacodynamics of ruxolitinib for the treatment of patients 2 years of age and younger with graft-vs-host disease.

CD22-directed CAR T-cell therapy generated high complete response rates and manageable safety in heavily pretreated patients with large B-cell lymphoma who relapsed following CD19-directed CAR T-cell therapy.

Checkpoint inhibitor–based salvage regimens significantly reduced the likelihood that patients with relapsed/refractory classic Hodgkin lymphoma undergoing transplant would need further salvage therapy vs conventional salvage regimens.

Orca-T produced a 100% overall survival rate in 8 patients with hematologic malignancies who received an allogeneic hematopoietic stem cell transplant with 7/8 non-permissive HLA mismatched donors.

Ruxolitinib induced clinically meaningful overall survival improvements by decreasing non-relapse mortality rates in patients with acute graft-vs-host-disease.

First-line treatment with itolizumab produced rapid, durable responses and favorable safety in patients with acute graft-vs-host disease.

Timing of severe symptom onset is the only distinct difference between late and classic acute graft-vs-host disease, and long-term outcomes were similar between the two types of disease.

Patients with relapsed or refractory multiple myeloma treated with the CAR T-cell agent idecabtagene vicleucel had comparable efficacy and safety outcomes regardless of whether they had renal impairment, according to findings from a real-world study.

Matthew Frank, MD, PhD, discusses findings from a single-institution phase 1 trial investigating autologous CAR T cells targeting CD22 in adults with large B-cell lymphoma, including those who relapse after or are refractory to CD19-directed CAR T-cell therapy.

Mayur Narkhede, MD, discusses findings from a pre-planned interim analysis of a phase 2 trial investigating siltuximab for the treatment of cytokine release syndrome and immune effector cell–associated neurotoxicity syndrome related to CAR T-cell therapy in adult patients with hematologic malignancies.

Surbhi Sidana, MD, discusses the feasibility of administering idecabtagene vicleucel in patients with relapsed/refractory multiple myeloma with renal impairment.

Nirav N. Shah, MD, discusses findings from a phase 1/2 study of lentiviral bispecific CAR T cells targeting CD20 and CD19 B-cell antigens in patients with relapsed or refractory mantle cell lymphoma.

Brexucabtagene autoleucel demonstrated a survival benefit in patients with relapsed/refractory B-cell acute lymphoblastic leukemia regardless of prior lines of treatment or exposure to blinatumomab or allogeneic stem cell transplant, according to data from subgroup analyses of the ZUMA-3 trial.

The presence of minimal residual disease led to a higher likelihood of relapse in patients with acute lymphoblastic leukemia who underwent hematopoietic cell transplant compared with those who had undetectable MRD pre and post transplant.

Haploidentical donors and posttransplant cyclophosphamide is a comparable alternative to matched unrelated donors for patients with myelofibrosis receiving blood or marrow transplant without matched sibling donors, although matched sibling donors, when available, remain the preferred donor option.

The fully-human scFv CD19-targeted CAR T-cell therapy JCAR021 elicited durable responses but with a high rate of neurotoxicity when administered at a dose of 7 x 106 cells/kg in patients with relapsed or refractory large B-cell lymphoma, according to data from a phase 1/2 trial.

ADI-001, a first-in-class, allogeneic gamma delta1 CAR T-cell therapy, elicited responses and demonstrated a favorable safety profile in patients with relapsed/refractory B-cell non-Hodgkin lymphoma.

The dual CD19- and CD20-directed, freshly administered CAR T-cell therapy zamtocabtagene autoleucel elicited a high response rate with deepening responses over time in patients with relapsed/refractory diffuse large B-cell lymphoma.

The combination of JSP191, fludarabine, and low-dose total body irradiation demonstrated facilitation of full donor myeloid chimerism, clearance of minimal residual disease, and a tolerable safety profile in patients with myelodysplastic syndrome or acute myeloid leukemia.

Administration of the SARS-CoV-2 vaccine resulted in heterogeneous immune response in patients with chronic graft-vs-host disease (cGVHD), further highlighting concerns about protection against infection or severe COVID-19 disease in this population
