Project description:IntroductionCD19-directed chimeric antigen receptor (CAR) T-cell therapy is a highly effective therapy for patients with relapsed/refractory large B-cell lymphoma (LBCL) and three CD19 CAR T-cell products (axicabtagene ciloleucel, tisagenlecleucel and lisocabtagene maraleucel) are currently approved for this indication. Despite the clinical benefit of CD19 directed CAR T-cell therapy, this treatment is associated with significant morbidity from treatment-emergent toxicities.Areas coveredThis Review discusses the safety considerations of axicabtagene ciloleucel in patients with LBCL. This includes discussion of the frequently observed immune-mediated toxicities of cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome. Additionally, we review CAR T-cell therapy related cytopenias, infection, organ dysfunction and the more recently described hemophagocytic lymphohistiocytosis.Expert opinionA thorough understanding of the toxicities associated with CD19-directed CAR T-cell therapy will facilitate the optimal selection of patients for this therapy. Furthermore, knowledge of preventative measures of CAR T-cell related complications, and early recognition and appropriate intervention will lead to the safe administration of these therapies, and ultimately improved outcomes for our patients.

Project description:The ZUMA-7 (Efficacy of Axicabtagene Ciloleucel Compared to Standard of Care Therapy in Subjects With Relapsed/Refractory Diffuse Large B Cell Lymphoma) study showed that axicabtagene ciloleucel (axi-cel) improved event-free survival (EFS) compared with standard of care (SOC) salvage chemoimmunotherapy followed by autologous stem cell transplant in primary refractory/early relapsed diffuse large B-cell lymphoma (DLBCL); this led to its recent US Food and Drug Administration approval in this setting. We modeled a hypothetical cohort of US adults (mean age, 65 years) with primary refractory/early relapsed DLBCL by developing a Markov model (lifetime horizon) to model the cost-effectiveness of second-line axi-cel compared with SOC using a range of plausible long-term outcomes. EFS and OS were estimated from ZUMA-7. Outcome measures were reported in incremental cost-effectiveness ratios, with a willingness-to-pay (WTP) threshold of $150 000 per quality-adjusted life-year (QALY). Assuming a 5-year EFS of 35% with second-line axi-cel and 10% with SOC, axi-cel was cost-effective at a WTP of $150 000 per QALY ($93 547 per QALY). axi-cel was no longer cost-effective if its 5-year EFS was ≤26.4% or if it cost more than $972 061 at a WTP of $150 000. Second-line axi-cel was the cost-effective strategy in 73% of the 10 000 Monte Carlo iterations at a WTP of $150 000. If the absolute benefit in EFS is maintained over time, second-line axi-cel for aggressive relapsed/refractory DLBCL is cost-effective compared with SOC at a WTP of $150 000 per QALY. However, its cost-effectiveness is highly dependent on long-term outcomes. Routine use of second-line chimeric antigen receptor T-cell therapy would add significantly to health care expenditures in the United States (more than $1 billion each year), even when used in a high-risk subpopulation. Further reductions in the cost of chimeric antigen receptor T-cell therapy are needed to be affordable in many regions of the world.

Project description:AbstractAxicabtagene ciloleucel (axi-cel) is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved for relapsed/refractory (R/R) follicular lymphoma (FL). Approval was supported by the phase 2, multicenter, single-arm ZUMA-5 study of axi-cel for patients with R/R indolent non-Hodgkin lymphoma (iNHL; N = 104), including FL and marginal zone lymphoma (MZL). In the primary analysis (median follow-up, 17.5 months), the overall response rate (ORR) was 92% (complete response rate, 74%). Here, we report long-term outcomes from ZUMA-5. Eligible patients with R/R iNHL after ≥2 lines of therapy underwent leukapheresis, followed by lymphodepleting chemotherapy and axi-cel infusion (2 × 106 CAR T cells per kg). The primary end point was ORR, assessed in this analysis by investigators in all enrolled patients (intent-to-treat). After median follow-up of 41.7 months in FL (n = 127) and 31.8 months in MZL (n = 31), ORR was comparable with that of the primary analysis (FL, 94%; MZL, 77%). Median progression-free survival was 40.2 months in FL and not reached in MZL. Medians of overall survival were not reached in either disease type. Grade ≥3 adverse events of interest that occurred after the prior analyses were largely in recently treated patients. Clinical and pharmacokinetic outcomes correlated negatively with recent exposure to bendamustine and high metabolic tumor volume. After 3 years of follow-up in ZUMA-5, axi-cel demonstrated continued durable responses, with very few relapses beyond 2 years, and manageable safety in patients with R/R iNHL. The ZUMA-5 study was registered at www.clinicaltrials.gov as #NCT03105336.

Project description:BackgroundAxicabtagene ciloleucel (axi-cel) is an autologous chimeric antigen receptor T-cell based anti-CD19 therapy. The ZUMA-1 study, multicenter, single-arm, registrational Phase 1/2 study of axi-cel demonstrated high objective response rate in patients with relapsed/refractory large B-cell lymphoma. Here, we present the results of the bridging study to evaluate the efficacy and safety of axi-cel in Japanese patients (JapicCTI-183914).MethodsThis study was the phase 2, multicenter, open-label, single-arm trial. Following leukapheresis, axi-cel manufacturing and lymphodepleting chemotherapy, patients received a single infusion of axi-cel (2.0 × 106 cells/kg). Bridging therapy between leukapheresis and conditioning chemotherapy was not allowed. The primary endpoint was objective response rate.ResultsAmong 17 enrolled patients, 16 received axi-cel infusion. In the 15 efficacy evaluable patients, objective response rate was 86.7% (95% confidence interval: 59.5-98.3%); complete response/partial response were observed in 4 (26.7%)/9 (60.0%) patients, respectively. No dose-limiting toxicities were observed. Grade ≥ 3 treatment-emergent adverse events occurred in 16 (100%) patients-most commonly neutropenia (81.3%), lymphopenia (81.3%) and thrombocytopenia (62.5%). Cytokine release syndrome occurred in 13 (81.3%) patients (12 cases of grade 1 or 2 and 1 case of grade 4). No neurologic events occurred. Two patients died due to disease progression, but no treatment-related death was observed by the data-cutoff date (October 23, 2019).ConclusionThe efficacy and safety of axi-cel was confirmed in Japanese patients with relapsed/refractory large B-cell lymphoma who have otherwise limited treatment options.Trial registrationJapicCTI-183914.

Project description:Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are CD19-directed chimeric antigen receptor T cell (CAR-T) therapies approved for relapsed/refractory aggressive large B cell lymphoma (LBCL). Significant costs and complex manufacturing underscore the importance of evidence-based counseling regarding the outcomes of these treatments. With the aim of examining the efficacy and safety of axi-cel versus tisa-cel in patients with relapsed/refractory aggressive LBCL, we performed a systematic literature search of comparative studies evaluating outcomes in relapsed/refractory aggressive LBCL after treatment with axi-cel or tisa-cel. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for response, progression-free survival (PFS), overall survival (OS), cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), and hematotoxicity. Meta-analysis and meta-regression were used to generate summary statistics. A total of 2372 participants were included in the 8 studies in our analysis. The dropout rate between apheresis and infusion was 13% for axi-cel versus 18% for tisa-cel, and the median time from apheresis to infusion was 32 days versus 45 days. Axi-cel showed higher odds for a complete response (OR, 1.65; P < .001) and was associated with higher odds for PFS at 1 year after infusion (OR, .60; P < .001). OS appeared to be improved with axi-cel (OR, .84; 95% CI, .68 to 1.02; P = .08), whereas the cumulative incidence of nonrelapse mortality (NRM) was 11.5% for axi-cel versus 3.7% for tisa-cel (P = .002). The main predictors for survival were lactate dehydrogenase level, Eastern Cooperative Oncology Group Performance Status, and response to bridging, and axi-cel maintained superior efficacy even in elderly patients. In terms of safety, axi-cel was associated with significantly higher odds of any-grade CRS (OR, 3.23; P < .001), but not of grade ≥3 CRS (P = .92). Axi-cel was associated with significantly higher odds of severe ICANS grade ≥3 (OR, 4.03; P < .001). In terms of hematotoxicity, axi-cel was significantly associated with higher odds of severe neutropenia at 1 month after infusion (OR, 2.06; P = .003). As a result, axi-cel was associated with significantly greater resource utilization, including prolonged hospital stay, more frequent intensive care admission, and use of agents such as tocilizumab for toxicity management. We provide strong evidence of the greater efficacy of axi-cel versus tisa-cel in relapsed/refractory aggressive LBCL. The higher toxicity and NRM seen with axi-cel might not counterbalance the overall results, highlighting the need for timely intervention and careful selection of patients, balancing resource utilization and clinical benefit.

Project description:PurposeAxicabtagene ciloleucel (axi-cel) is an autologous CD19-directed chimeric antigen receptor (CAR) T-cell therapy approved for relapsed/refractory large B-cell lymphoma (LBCL) on the basis of the single-arm phase II ZUMA-1 trial, which showed best overall and complete response rates in infused patients of 83% and 58%, respectively. We report clinical outcomes with axi-cel in the standard-of-care (SOC) setting for the approved indication.Patients and methodsData were collected retrospectively from all patients with relapsed/refractory LBCL who underwent leukapheresis as of September 30, 2018, at 17 US institutions with the intent to receive SOC axi-cel. Toxicities were graded and managed according to each institution's guidelines. Responses were assessed as per Lugano 2014 classification.ResultsOf 298 patients who underwent leukapheresis, 275 (92%) received axi-cel therapy. Compared with the registrational ZUMA-1 trial, 129 patients (43%) in this SOC study would not have met ZUMA-1 eligibility criteria because of comorbidities at the time of leukapheresis. Among the axi-cel-treated patients, grade ≥ 3 cytokine release syndrome and neurotoxicity occurred in 7% and 31%, respectively. Nonrelapse mortality was 4.4%. Best overall and complete response rates in infused patients were 82% (95% CI, 77% to 86%) and 64% (95% CI, 58% to 69%), respectively. At a median follow-up of 12.9 months from the time of CAR T-cell infusion, median progression-free survival was 8.3 months (95% CI, 6.0 to15.1 months), and median overall survival was not reached. Patients with poor Eastern Cooperative Oncology Group performance status of 2-4 and elevated lactate dehydrogenase had shorter progression-free and overall survival on univariable and multivariable analysis.ConclusionThe safety and efficacy of axi-cel in the SOC setting in patients with relapsed/refractory LBCL was comparable to the registrational ZUMA-1 trial.

Project description:BackgroundIn a phase 1 trial, axicabtagene ciloleucel (axi-cel), an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, showed efficacy in patients with refractory large B-cell lymphoma after the failure of conventional therapy.MethodsIn this multicenter, phase 2 trial, we enrolled 111 patients with diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, or transformed follicular lymphoma who had refractory disease despite undergoing recommended prior therapy. Patients received a target dose of 2×106 anti-CD19 CAR T cells per kilogram of body weight after receiving a conditioning regimen of low-dose cyclophosphamide and fludarabine. The primary end point was the rate of objective response (calculated as the combined rates of complete response and partial response). Secondary end points included overall survival, safety, and biomarker assessments.ResultsAmong the 111 patients who were enrolled, axi-cel was successfully manufactured for 110 (99%) and administered to 101 (91%). The objective response rate was 82%, and the complete response rate was 54%.With a median follow-up of 15.4 months, 42% of the patients continued to have a response, with 40% continuing to have a complete response. The overall rate of survival at 18 months was 52%. The most common adverse events of grade 3 or higher during treatment were neutropenia (in 78% of the patients), anemia (in 43%), and thrombocytopenia (in 38%). Grade 3 or higher cytokine release syndrome and neurologic events occurred in 13% and 28% of the patients, respectively. Three of the patients died during treatment. Higher CAR T-cell levels in blood were associated with response.ConclusionsIn this multicenter study, patients with refractory large B-cell lymphoma who received CAR T-cell therapy with axi-cel had high levels of durable response, with a safety profile that included myelosuppression, the cytokine release syndrome, and neurologic events.

Project description:Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) have both demonstrated impressive clinical activity in relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL). In this study, we analyzed the outcome of 809 patients with R/R DLBCL after two or more previous lines of treatment who had a commercial chimeric antigen receptor (CAR) T cells order for axi-cel or tisa-cel and were registered in the retrospective French DESCAR-T registry study ( NCT04328298 ). After 1:1 propensity score matching (n = 418), the best overall response rate/complete response rate (ORR/CRR) was 80%/60% versus 66%/42% for patients treated with axi-cel compared to tisa-cel, respectively (P < 0.001 for both ORR and CRR comparisons). After a median follow-up of 11.7 months, the 1-year progression-free survival was 46.6% for axi-cel and 33.2% for tisa-cel (hazard ratio (HR) = 0.61; 95% confidence interval (CI), 0.46-0.79; P = 0.0003). Overall survival (OS) was also significantly improved after axi-cel infusion compared to after tisa-cel infusion (1-year OS 63.5% versus 48.8%; HR = 0.63; 95% CI, 0.45-0.88; P = 0.0072). Similar findings were observed using the inverse probability of treatment weighting statistical approach. Grade 1-2 cytokine release syndrome was significantly more frequent with axi-cel than with tisa-cel, but no significant difference was observed for grade ≥3. Regarding immune effector cell-associated neurotoxicity syndrome (ICANS), both grade 1-2 and grade ≥3 ICANS were significantly more frequent with axi-cel than with tisa-cel. In conclusion, our matched comparison study supports a higher efficacy and also a higher toxicity of axi-cel compared to tisa-cel in the third or more treatment line for R/R DLBCL.

Project description:Neurological toxicity following chimeric antigen receptor T-cell infusion, termed immune cell-associated neurotoxicity syndrome (ICANS), is a common and limiting factor in the expansion of this promising treatment modality. While refractory cases of ICANS have been reported in clinical trials, there is limited description of these presentations and their associated treatment. The use of predictive biomarkers and risk stratification tools offer a means of identifying patients with higher likelihood of developing ICANS; however, their discriminatory sensitivity has been shown to vary depending on disease type. In this case report, we present the clinical course of a patient with diffuse large B-cell lymphoma treated with axicabtagene ciloleucel who developed a nonsinusoidal pattern of severe neurotoxicity refractory to steroid treatment, and we evaluate the predictive value of commonly used biomarkers and risk scores in assessing the likelihood of her presentation. In assessing the efficacy of these scores in the context of our patient's pattern of severe neurotoxicity exacerbations, we aim to provide valuable clinical insight to better manage refractory ICANS and ultimately improve patient outcomes.

Project description:ImportanceChimeric antigen receptor (CAR) T cell therapies are approved as a third-line or later therapy for several hematological malignant neoplasms. Recently, randomized clinical trials have investigated their efficacy as a second-line treatment in high-risk relapsed or refractory diffuse large B-cell lymphoma (DLBCL) compared with salvage chemotherapy followed by hematopoietic stem cell transplantation (HSCT).ObjectiveTo evaluate the cost-effectiveness of axicabtagene ciloleucel and tisagenlecleucel vs standard care (SC) as second-line or later therapy for relapsed or refractory DLBCL, from both US health care sector and societal perspectives at a cost-effectiveness threshold of $150 000 per quality-adjusted life-year (QALY).Design, setting, and participantsThis economic evaluation assessed cost-effectiveness using a partitioned survival model with 2021 US dollars and QALYs over a lifetime horizon. Model inputs were derived from 2 randomized clinical trials (ZUMA-7 and BELINDA) and published literature. In the trials, patients who did not respond to SC received CAR T cells (treatment switching or crossover), either outside the protocol (ZUMA-7) or as part of the protocol (BELINDA). A separate scenario analysis compared second-line axicabtagene ciloleucel with SC alone without treatment crossover to CAR T cell therapy. Data analysis was performed from December 18, 2021, to September 13, 2022.ExposuresCAR T cell therapy (axicabtagene ciloleucel and tisagenlecleucel) compared with salvage chemotherapy followed by HSCT.Main outcomes and measuresCosts and QALYs were used to derive incremental cost-effectiveness ratios (ICERs) for the health care sector and societal perspectives. Cost and QALYs were discounted at 3.0% annually. Univariate and multivariate probabilistic sensitivity analysis using 10 000 Monte Carlo simulations were applied to test model uncertainty on the ICER.ResultsSecond-line axicabtagene ciloleucel was associated with an ICER of $99 101 per QALY from the health care sector perspective and an ICER of $97 977 per QALY from the societal perspective, while second-line tisagenlecleucel was dominated by SC (incremental costs of $37 803 from the health care sector and $39 480 from the societal perspective with decremental QALY of -0.02). Third-line or later tisagenlecleucel was associated with an ICER of $126 593 per QALY from the health care sector perspective and an ICER of $128 012 per QALY from the societal perspective. Based on the scenario analysis of no treatment switching, second-line axicabtagene ciloleucel yielded an ICER of $216 790 per QALY from the health care sector perspective and an ICER of $218 907 per QALY from the societal perspective, compared with SC. When accounting for patients achieving prolonged progression-free survival who would not incur progression-related costs, in this scenario ICER changed to $125 962 per QALY from the health care sector perspective and $122 931 per QALY from the societal perspective. These results were most sensitive to increased list prices of CAR T cell therapy and QALY losses associated with axicabtagene ciloleucel and tisagenlecleucel.Conclusions and relevanceThese findings suggest that second-line axicabtagene ciloleucel and third-line or later tisagenlecleucel were cost-effective in treating patients with relapsed or refractory DLBCL at the cost-effectiveness threshold of $150 000 per QALY. However, uncertainty remains regarding the best candidates who would experience value gains from receiving CAR T cell therapy.
