- |||||||||| Characterization of Infectious Complications during the Expected Duration of Cytokine Release Syndrome (CRS) in Patients Receiving CAR T Cell Therapy () - Dec 11, 2023 - Abstract #TCTASTCTCIBMTR2024TCT_ASTCT_CIBMTR_905;
We retrospectively reviewed 191 patients treated with autologous CAR T cell products (idecabtagene vicleucel, ciltacabtagene autoleucel, tisagenlecleucel, axicabtagene ciloleucel, brexucabtagene autoleucel, lisocabtagene maraleucel) at Mount Sinai Hospital from April 2017 until February 2023...Levofloxacin as prophylaxis was given to 35% (60/170). These results suggest that judicious use of broad-spectrum antibiotics and limited infectious workup may be considered in clinically stable and non-neutropenic patients with CRS occurring during the pre-specified period post CAR T cell infusion.

T-Cell Large Granular Lymphocyte Population Involving Chimeric Antigen Receptor-Modified T (CAR T) Cells in Patients with Cytopenia after CD19-Targeted CAR T-Cell Therapy: Case Series () - Dec 11, 2023 - Abstract #TCTASTCTCIBMTR2024TCT_ASTCT_CIBMTR_897; A 52-year-old (y/o) female (F) with R/R primary mediastinal B-cell lymphoma with central nervous system (CNS) involvement was treated with out-of-specification tisagenlecleucel...A 62 y/o F with R/R diffuse LBCL (DLBCL), NOS and chronic hepatitis B was treated with axicabtagene ciloleucel...A 50 y/o F, with R/R DLBCL, NOS with CNS involvement and history of cold agglutinin disease was treated with lisocabtagene maraleucel...In two of the patients, a subset of the clonal population expressed the CAR transgene. This case series highlights T-LGL as a potential cause of PC after CAR-T therapy.

Review, Journal, CAR T-Cell Therapy: Evolving Role of CAR T Cell Therapy in First- and Second-Line Treatment of Large B Cell Lymphoma. (Pubmed Central) - Nov 13, 2023 ZUMA-12 demonstrated effectiveness for axi-cel as part of first-line treatment for high-risk LBCL. These results support a role for CAR T cell therapy as new second-line SOC for r/r LBCL and highlight its potential evolution into future first-line treatment for high-risk disease.

Patterns and Safety of Glucocorticosteroids Use Following CD19 CAR-T Cell Therapy for B-Cell Lymphoma (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_6347; Steroids were expressed as dexamethasone equivalent...Results : 292 patients with R/R B-NHL received commercial CAR-T cell therapy (48% axi-cel, 24% tisa-cel, 22% liso-cel, and 6% Brexu-cel), primarily for large B cell cell lymphoma (85%), mantle cell (11%) or follicular (4%) lymphoma...The discrepancy is likely due to our study's exclusion of steroid use prior to CAR-T and statistical analysis. Overall, our findings suggest that steroid administration for CAR-T cell therapy toxicity management is safe and does not appear to have a negative impact on efficacy.

Real-World Outcomes in Patients with Transformed Follicular Lymphoma Treated with CD19-Targeting CAR-T Therapy (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_6346; CD19-targeting CAR-T cell therapy is effective for pts with relapsed/refractory tFL, including patients with characteristics of poor prognosis, with efficacy and toxicity profiles comparable to that observed in previous DLBCL studies. Unfortunately, pts who relapse post-CAR-T therapy have limited effective therapeutic options available, and this currently remains an unmet medical need within the field.

Higher CD4+ T Cell Counts after CAR-T in Large B-Cell Lymphomas Are Significantly Associated with Better Overall Survival (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_6268; Methods Adult patients with primary or transformed LBCL treated with CD19-CAR-T cells, namely axicabtagene ciloleucel (axi-cel), tisagenlecleucel (tisa-cel), and lisocabtagene maraleucel (liso-cel), between 2017 and 2022 were included in this single center retrospective study...Lymphodepletion was mostly cyclophosphamide and fludarabine (82.4%)...Additionally, we identified several factors that impact IR, which in turn shapes OS. In doing so, we show that CD4+ T lymphocytes are key players in disease response post-CAR-T and suggest that tracking CD4+ recovery following CAR-T may provide both diagnostic and therapeutic benefit.
- |||||||||| CNS Radiotherapy As Bridging Prior to CAR T-Cell Therapy for Non-Hodgkin B-Cell Lymphoma (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_5934;
While overall numbers are limited to date, the rate of severe CRS and ICANS is similar to that of historical series of CNSL patients treated with CAR T. However, a larger cohort will be required to determine the safety of CNS-BRT. These data support further study of RT, and exploration of involved site brain RT, as an effective bridging modality for CAR T-cell therapy in CNSL.

P1 One of the two patients received prior alemtuzumab in combination with a CAR19 product, likely contributing to the failure. Among the 38 who were successfully manufactured, 37 patients had received prior CAR19, including axi-cel (n = 28), tisa-cel (n = 3), liso-cel (n = 3), autologous CAR19 in clinical trial (n = 1), bispecific CD19/CD22 CAR-T (n = 1), and bispecific CD19/CD20 CAR-T (n = 1).

CMV reactivation is a common complication of CAR T cell therapy in CMV seropositive individuals. Although confirmatory studies are needed, our data shows that administration of immunosuppression, in particular steroids, for management of CAR T cell toxicities is a major risk factor for CMV reactivation, and close monitoring for preemptive therapy or antiviral prophylaxis might be indicated in this setting.

In TIL and dDLBCL cohorts, 76%/73% received axicabtagene ciloleucel, 17%/18% tisagenlecleucel, and 7%/10% lisocabtagene maraleucel, respectively...In TIL and dDLBCL cohorts, respectively, 49%/59% of pts received tocilizumab for CRS and 41%/51% received steroids for CRS or ICANS...The results indicate that CD19CAR T is tolerable and active in pts with r/r TIL with safety and efficacy outcomes similar to that observed in pts with dDLBCL. Our findings suggest CD19CAR T cell therapy may be able to overcome the historically poor prognosis associated with r/r TIL.

Evaluation of the T-Cell Metabolic State of Starting Material and Manufactured CAR T Cell Products and Clinical Outcome of CAR T-Cell Therapy for Large B Cell Lymphoma (SDCC - Halls G-H) - Nov 3, 2023 - Abstract #ASH2023ASH_4400; P1 Methods Samples were obtained from large B cell lymphoma (LBCL) patients that were part of the TRANSCEND-NHL-001 trial (NCT02631044, Abramson et al, Lancet 2020).Thirty-two patients with r/r B-cell lymphoma who received CAR-T cell treatment lisocabtagene maraleucel (16 responders (R) and 16 non-responders (NR)) were included in our analyses and (metabolically) analyzed by flow cytometry and extracellular flux analysis...More specifically, a higher abundance of memory phenotypes, metabolic activity and mitochondrial biogenesis of both harvested T cells and CAR-T product associates with improved clinical response. Combining metabolic, phenotypical and clinical characteristics and biomarkers of patient T cells (both pre- or post-production) shows the importance of the metabolic phenotype and fitness of T cell starting material, underlying the importance of early line CAR T therapy following diagnosis.

This warrants further study of optimal CNS-directed treatment strategies prior to CAR-T, development of novel cellular therapy platforms or consideration of post CAR-T maintenance therapy in these high-risk patients.
