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 according to ASTCT criteria and responses were assessed as per Lugano 2014 classification. Of 91 patients who underwent leukapheresis, 75 (82%) received tisa-cel therapy. Grade 3 or higher cytokine release syndrome and neurotoxicity occurred in 5% and 1%, respectively; non-relapse mortality was 4%. Among the infused patients, best ORR and CR were 60% and 32%, respectively, with a median duration of response of 8.9 months. With a median follow-up of 14.1 months from CAR T-cell infusion, median progression-free survival and overall survival were 3 months and 10.7 months, respectively. At 12 months, patients in CR at first disease evaluation had a PFS of 87% and OS of 93%. Patients with an elevated lactate dehydrogenase showed a shorter PFS and OS on multivariate analysis. Treatment with tisa-cel for patients with relapsed/refractory LBCL in a European SOC setting showed a manageable safety profile and durable complete responses

Anakinra for Refractory Cytokine Release Syndrome or Immune Effector Cell-Associated Neurotoxicity Syndrome after Chimeric Antigen Receptor T Cell Therapy
Chimeric antigen receptor-engineered (CAR)-T cell therapy remains limited by significant toxicities, including cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). The optimal management of severe and/or refractory CRS/ICANS remains ill- defined. Anakinra has emerged as a promising agent based on preclinical data, but its safety and efficacy in CAR-T therapy recipients are unknown. The primary objective of this study was to evaluate the safety of anakinra to treat refractory CRS and ICANS after CAR-T therapy. The secondary objective was to evaluate the impact of key treatment-, patient-, and disease-related variables on the time to CRS/ICANS resolution and treatment-related mortality (TRM). We retrospectively analyzed the outcomes of 43 patients with B cell or plasma cell malignancies treated with anakinra for refractory CRS or ICANS at 9 institutions in the United States and Spain between 2019 and 2022. Cause- specific Cox regression was used to account for competing risks. Multivariable cause-specific Cox regression was used to estimate the effect of anakinra dose on outcomes while minimizing treatment allocation bias by including age, CAR-T product, prelymphodepletion (pre-LD) ferritin, and performance status. Indications for anakinra treatment were grade >/=2 ICANS with worsening or lack of symptom improvement despite treatment with high-dose corticosteroids (n = 40) and grade >/=2 CRS with worsening symptoms despite treatment with tocilizumab (n = 3). Anakinra treatment was feasible and safe; discontinuation of therapy because of anakinra-related side effects was reported in only 3 patients (7%). The overall response rate (ORR) to CAR-T therapy was 77%. The cumulative incidence of TRM in the whole cohort was 7% (95% confidence interval [CI], 2% to 17%) at 28 days and 23% (95% CI, 11% to 38%) at 60 days after CAR-T infusion. The cumulative incidence of TRM at day 28 after initiation of anakinra therapy was 0% in the high-dose (>200 mg/day i.v.) recipient group and 47% (95% CI, 20% to 70%) in the low-dose (100 to 200 mg/day s.c. or i.v.) recipient group. The median cumulative incidence of CRS/ICANS resolution from the time of anakinra initiation was 7 days in the high-dose group and was not reached in the low-dose group, owing to the high TRM in this group. Univariate Cox modeling suggested a shorter time to CRS/ICANS resolution in the high-dose recipients (hazard ratio [HR], 2.19; 95% CI, .94 to 5.12; P = .069). In a multivariable Cox model for TRM including age, CAR-T product, pre-LD ferritin level, and pre-LD Karnofsky Performance Status (KPS), higher anakinra dose remained associated with lower TRM (HR, .41 per 1 mg/kg/day increase; 95% CI, .17 to .96; P = .039. The sole factor independently associated with time to CRS/ICANS resolution in a multivariable Cox model including age, CAR-T product, pre-LD ferritin and anakinra dose was higher pre-LD KPS (HR, 1.05 per 10% increase; 95% CI, 1.01 to 1.09; P = .02). Anakinra treatment for refractory CRS or ICANS was safe at doses up to 12 mg/kg/day i.v. We observed an ORR of 77% after CAR-T therapy despite anakinra treatment, suggesting a limited impact of anakinra on CAR-T efficacy. Higher anakinra dose may be associated with faster CRS/ICANS resolution and was independently associated with lower TRM. Prospective comparative studies are needed to confirm our findings
A national service for delivering CD19 CAR-Tin large B-cell lymphoma – The UK real-world experience
CD19 CAR-T have emerged as a new standard treatment for relapsed/refractory (r/r) large B-cell lymphoma (LBCL). CAR-T real-world (RW) outcomes published to date suggest significant variability across countries. We provide results of a large national cohort of patients intended to be treated with CAR-T in the UK. Consecutive patients with r/r LBCL approved for CAR-T by the National CAR-T Clinical Panel between December 2018 and November 2020 across all UK CAR-T centres were included. 404/432 patients were approved [292 axicabtagene ciloleucel (axi-cel), 112 tisagenlecleucel (tisa-cel)], 300 (74%) received the cells. 110/300 (38.3%) patients achieved complete remission (CR) at 6 months (m). The overall response rate was 77% (52% CR) for axi-cel, 57% (44% CR) for tisa-cel. The 12-month progression-free survival was 41.8% (axi-cel) and 27.4% (tisa-cel). Median overall survival for the intention-to-treat population was 10.5 m, 16.2 m for infused patients. The incidence of grade ≥3 cytokine release syndrome and neurotoxicity were 7.6%/19.6% for axi-cel and 7.9%/3.9% for tisa-cel. This prospective RW population of CAR-T eligible patients offers important insights into the clinical benefit of CD19 CAR-T in LBCL in daily practice. Our results confirm long-term efficacy in patients receiving treatment similar to the pivotal trials, but highlight the significance of early CAR-T failure
