• FDA Adverse Events Reporting System data show 20% of chimeric antigen receptor T cell therapy adverse events were cardiovascular adverse events (CVEs). • CVEs had all-cause mortality of 30%. • Arrhythmias were the most frequent CVEs. • Neurotoxicity/immune effector cell-associated neurotoxicity syndrome clustered with CVEs and cytokine release syndrome Chimeric antigen receptor (CAR) T cell therapy is approved in the United States for the treatment of acute lymphocytic leukemia and aggressive B cell lymphomas. Multiple cardiovascular adverse events (CVEs) associated with CAR-Ts have been observed in small studies, but no large-scale studies exist. Leveraging the Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS), we identified all reported adverse events (AEs) associated with CAR-T therapy (tisagenlecleucel and axicabtagene ciloleucel) from 2017 to 2019. Reports with missing age and sex were excluded. CVEs were classified into arrhythmias, heart failure (HF), myocardial infarction (MI), and other CVEs. Logistic regression and hierarchical clustering were used to identify factors associated with CVEs. A total of 996 reported AEs were observed (39.1% associated with tisagenlecleucel and 60% with axicabtagene ciloleucel). Of all patients experiencing AEs, the median age was 54 (interquartile range, 21 to 65) years; 38.9% were females. In total, 19.7% (196) of all AEs reported to the FDA were CVEs. The most common CVEs were arrhythmia (77.6%), followed by HF (14.3%) and MI (0.5%). In adjusted analysis a positive association was observed between those presenting with CVE with neurotoxicity (odds ratio, 1.76; 95% confidence interval, 1.20 to 2.60; P =.004). Additionally, when both CVE and cytokine release syndrome (CRS) are present, neurotoxicity is the most common noncardiac AE, which clusters with them (Jaccard similarity: 73.1). The mortality rate was 21.1% overall but 30.1% for those reporting CVEs. In FAERS, reported CVEs with CAR-T are associated with high reported mortality. The development of either CRS or neurotoxicity should prompt vigilance for cardiovascular events. Image, graphical abstract [ABSTRACT FROM AUTHOR]

• Haploidentical stem cell transplantation with post-transplant cyclophosphamide can be considered a viable option in children with Fanconi anemia, particularly in resource-limited settings given the high costs of hematopoietic stem cell transplantations, with an overall survival of 68.4%. • Peripheral blood stem cells provide early engraftment, decreasing the risk of prolonged neutropenia and sepsis, with a focus on maintaining CD34 and CD3 dose of a minimum of 5 × 106/kg and 1.5 × 108/kg recipient body weight, respectively, in the infused graft. • Supportive care measures, including N -acetyl cysteine infused concomitantly with cyclophosphamide on day +3 and day +4, can help decrease the incidence of severe mucositis and transaminitis and thereby reduce regimen-related toxicity. • Monitoring ferritin as a surrogate marker for IL-6 levels and cytokine release syndrome with log increases combined with clinical features as the basis for instituting early steroids can decrease the mortality associated with cytokine release syndrome. • Ruxolitinib can be a useful second-line agent for chronic graft-versus-host disease (GVHD) with good responses in those with skin and mouth GVHD. Fanconi anemia is the most common inherited bone marrow failure syndrome, and hematopoietic stem cell transplantation (HSCT) is the only curative option. Post-transplant cyclophosphamide (PTCy) is challenging in this group of children, given their increased sensitivity to chemotherapy. We performed a retrospective analysis of the data on children diagnosed with Fanconi anemia who underwent a haploidentical HSCT with PTCy from January 2014 to December 2019. Nineteen children (male/female, 0.75:1) underwent 21 haplo-HSCTs with PTCy. Fludarabine, low-dose cyclophosphamide, and 200 centi-gray total body irradiation were included in the conditioning regimen with 25 mg/kg PTCy on days +3 and +4. Haplo-graft was from a sibling in 38% and father in 57% of transplants. The source of stem cells was peripheral blood stem cells in 81% and bone marrow in 19% of transplants, with a median CD34 dose of 5.0 × 106/kg. We documented engraftment in 84% and primary graft failure in 10% of transplants. N -acetylcysteine (NAC) was infused concomitantly during cyclophosphamide in 13 children. Grade 2 and 3 mucositis was lower among those who received NAC as compared to those who did not (30% and 15% versus 33% and 50%), while transaminitis was higher among those who did not receive the infusion. The incidence of acute graft-versus-host disease (GVHD) was 68%, and 81% of these were steroid responsive (grade I/II). We documented chronic GVHD in 25% children, predominantly involving the skin and mouth, which responded to low-dose steroids and ruxolitinib. Serum ferritin was monitored twice weekly as a surrogate marker for cytokine release syndrome due to nonavailability of IL-6 levels. A 1- or 2-log increase in the titers of ferritin associated with clinical features guided the early addition of steroids in the periengraftment period. The mean survival was found to be less among those with high serum ferritin (>10,000 ng/dL) in the periengraftment period as compared to those with ferritin <10,000 ng/dL (mean survival of 25 ± 10 months versus 50 ± 6 months, respectively). The overall survival in our cohort was 68.4%, with a mean survival time of 41.5 months (95% confidence interval, 29.3 to 53.8 months), with a statistically significant correlation between inferior outcome and having received over 15 transfusions before HSCT (P =.01). PTCy can be considered a viable option in children with Fanconi anemia, particularly in resource-limited settings given the high costs of HSCTs. Focused interventions in this subset of children help improve survival outcomes. Early identification of cytokine release syndrome and risk-adapted steroid therapy during engraftment helps prevent mortality. The concomitant use of NAC during cyclophosphamide infusion helps reduce oxygen free radical related tissue damage and regimen-related toxicity. [ABSTRACT FROM AUTHOR]

A consensus grading schema for cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) resulting from chimeric antigen receptor (CAR) T cell therapy was published in 2019. Although this consensus grading schema has been imperative in identifying and monitoring CRS and ICANS in our CAR T cell population, we observed patients exhibiting subtle neurotoxicity symptoms prior to a decrease in their immune effector cell (ICE) score, which is one component of ICANS. Because we treat grade 1 ICANS at our institution, identification of early neurotoxicity symptoms is important. Additionally, we found changes in personality, occupational confusion, or inability to answer dichotomous questions were early signs of neurotoxicity. Therefore, we developed a 3-step command tool to supplement the ICE evaluation. We present 2 examples of patients who exhibited early neurotoxicity symptoms and led us to develop this tool and 1 in whom it was effective. We propose that CAR T cell patients are consistently followed by a clinical care provider who is familiar with the patient to recognize early changes in personality, behavior, and cognition. Additionally, we propose that the multistep command tool be used in conjunction with the ICE score to detect early symptoms of ICANS. Early intervention has the potential to prevent irreversible neurotoxicity. [ABSTRACT FROM AUTHOR]

• Direct cross-trial comparison of axi-cel (ZUMA-1) and tisa-cel (JULIET) chimeric antigen receptor T products is not feasible. • Matching adjusted indirect comparison successfully adjusted for differences in patient characteristics between ZUMA-1 and JULIET. • Axi-cel had a higher objective response, complete response, and overall survival than tisa-cel. • Axi-cel had higher grade 1 to 2 cytokine release syndrome (CRS) while both products had similar grade ≥3 CRS and neurologic events. Axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) are autologous anti-CD19 chimeric antigen receptor T (CAR T) cell therapies for the treatment of patients with relapsed/refractory large B cell lymphoma (RR-LBCL). Both can induce durable responses; however, cross-trial comparisons are difficult due to differences in study design. In this study, the registration trials of axi-cel and tisa-cel were compared using a matching adjusted indirect comparison (MAIC). A MAIC was performed to adjust for differences in patient characteristics between trials. The estimates for the ZUMA-1 (axi-cel) trial were adjusted using patient-level data to match the study population in JULIET (tisa-cel) for key variables: International Prognostic Index), Eastern Cooperative Oncology Group score, stage, refractoriness or relapsed disease, double/triple hit status, cell of origin, and number of prior lines of therapy. The endpoints analyzed were response, overall survival (OS), and adverse events. After adjusting for differences in patient characteristics between trials, axi-cel was associated with a greater objective response rate (relative risk [RR]=1.61; 95% confidence interval [CI], 1.29 to 2.01) and complete response (RR = 1.62; 95% CI, 1.16 to 2.27) than tisa-cel among patients who underwent infusion. The OS from infusion onward comparing axi-cel to tisa-cel had a hazard ratio of 0.51 (95% CI, 0.31 to 0.83). The indirect comparison showed a higher rate of grade 1 to 2 cytokine release syndrome (CRS) in ZUMA-1 compared with JULIET (RR = 2.03; 95% CI, 1.55 to 2.65) and similar rates of grade ≥3 CRS and neurologic events. In the absence of a direct head-to-head study, the MAIC statistical technique suggests axi-cel may have superior efficacy but a greater risk of grade 1 to 2 CRS. Future real-world studies can further inform the relative efficacy and safety of CAR T therapies in RR-LBCL. [ABSTRACT FROM AUTHOR]

• The severity of cytokine release syndrome (CRS) developing after T cell-replete haploidentical hematopoietic cell transplantation is associated with an increased risk of bacterial and viral infections. • Severe CRS significantly and independently increases the risk of viral infections but mediates the risk of bacterial infections through an effect on neutrophil recovery. • CRS grade is also a significant predictor for infection density (overall, bacterial, and viral) after adjusting for other predictors, including time to neutrophil engraftment. An increased risk of infections has been described after T cell-replete haploidentical cell transplantation (haploHCT). Cytokine release syndrome (CRS) after haploHCT is a known phenomenon, but the impact of CRS severity on the risk of infections remains unexplored. We retrospectively evaluated 78 consecutive adult haploHCT recipients from 2012 to 2018 for the development of CRS (graded based on the criteria of Lee et al) and examined the incidence and mortality due to infections in correlation with CRS severity. In our study cohort, which was stratified into 3 groups by severity of CRS, 80% of the patients developed infections within 180 days of HCT. Significantly higher proportions of patients with CRS grade 2 (89%) and grade ≥3 (90%) than patients with CRS grade 0-1 (68%) had at least 1 infection in the first 100 days (P =.04). Bloodstream infections (BSIs) were seen more frequently in patients with CRS grade 2 and grade ≥3 in the first 6 months. Multivariable analysis for time to infection showed that CRS grade ≥3 was independently associated with an elevated risk of any infection compared with CRS grade 0-1 (hazard ratio [HR], 3.05; P =.007). CRS grade ≥3 was also associated with a higher hazard of viral (HR, 3.42; P =.04) and bacterial infections (HR, 2.83; P =.03) compared with CRS grade 0-1. After adjusting for time to neutrophil engraftment as a time-dependent covariate, CRS grade ≥3 still had a significant effect on viral infections (HR, 2.49; P =.03), but not on bacterial infections (HR, 1.32; P =.57). CRS grade was also a significant predictor for infection density (overall, bacterial, and viral). The incidence of infection-related mortality by day +100 was higher in patients with severe CRS. Severe CRS developing after post-transplantation cyclophosphamide-based haploHCT is independently associated with viral infections and an increased risk of bacterial infections, likely through delayed neutrophil engraftment.

• CAR T cells might be a salvage option for lymphoma relapse after alloHCT. • Information on CAR T cells in B cell lymphoma after a prior alloHCT is limited. • After prior alloHCT, CD19 CAR T cell treatment in lymphoma is feasible and effective. • CAR T cells did not induce or exacerbate the risk of acute or chronic GVHD. • Protracted cytopenia after CAR T cell treatment is a matter of concern. Although CD19-directed chimeric antigen receptor (CAR) T cells have been successfully used after a preceding allogeneic stem cell transplant (alloHCT) in patients with acute lymphoblastic leukemia, little is known about the feasibility and outcome of CAR T cell treatment in patients who have been previously allotransplanted for lymphoma. In a single-center retrospective analysis, course and outcome of all allografted patients treated with CD19 CAR constructs for B cell lymphoma between October 2018 and November 2019 were studied. CAR therapy consisted either of a third-generation CAR (HD-CAR-1) or of commercially manufactured axicabtagene ciloleucel (axi-cel; Gilead, Santa Monica, U.S.). Altogether, 10 CAR T cell dosings using recipient leukapheresis products were performed in 8 patients: 4 patients (2 mantle cell lymphoma, 2 chronic lymphocytic leukemia) received 6 dosings with HD-CAR-1 and 4 patients (all with diffuse large B cell lymphoma) received 4 dosings with axi-cel. Overall, 6 of 8 patients (75%) responded. CAR treatment was well tolerated with grade ≥ 3 cytokine release syndrome and neurotoxicity each being observed after 1 of 10 dosings. A single patient had moderate chronic graft-versus-host disease. Of note, 3 of 4 patients who received axi-cel had ongoing grade ≥ 3 cytopenia 3 months postdosing, whereas prolonged cytopenia was not observed in 9 alloHCT-naive patients who received axi-cel during the same time period. In conclusion, CAR T cell treatment from recipient-derived leukapheresis products after a prior alloHCT appears to be feasible, effective, and safe in patients with B cell lymphoma. Protracted cytopenia after axi-cel treatment is a matter of concern and requires further exploration. [ABSTRACT FROM AUTHOR]

• The incidence of acute kidney injury following chimeric antigen receptor T cell (CAR-T) cell therapy is low. • Previous hematopoietic cell transplantation, intensive care unit admission, and grade 3-4 cytokine release syndrome after CAR-T therapy may increase the risk of acute kidney injury (AKI). • Most patients who experience AKI after CAR-T therapy recover kidney function. Chimeric antigen receptor (CAR) T cell therapy using engineered cytotoxic T cells has shown promising responses in various hematologic malignancies. Cytokine release syndrome (CRS) and immune effector cell-associated neurologic syndrome (ICANS) are recognized toxicities of CAR-T, whereas kidney injury remains less well recognized. The objective of the present study was to identify the incidence of acute kidney injury (AKI) after CAR-T cell therapy, potential risk factors, and recovery of kidney function. We performed a retrospective review of 46 adult patients with non-Hodgkin lymphoma treated with CAR-T therapy between February 2018 and February 2019 at our institution. Serum creatinine values before CAR-T therapy through day 100 were used to assess AKI, as defined by the Kidney Disease Improving Global Outcomes (KDIGO) criteria: grade 1, 1.5- to <2-fold of baseline; grade 2, 2- to <3-fold of baseline; grade 3, ≥3-fold of baseline. CRS and ICANS were graded using the consensus criteria of the American Society of Transplantation and Cellular Therapy. The overall incidence of CRS was 78.3% (95% confidence interval [CI], 66% to 90.5%), of whom 13% (95% CI, 3.3% to 22.8%) developed grade 3-4 CRS, whereas the overall incidence of ICANS was lower at 45.7% (95% CI, 3.1% to 60.3%). The cumulative incidence of any grade AKI by day 100 was 30% (95% CI, 16.9% to 43.9%), with a grade 1 AKI incidence of 21.7% (95% CI, 9.7% to 33.8%) and a grade 2-3 AKI incidence of 8.7% (95% CI,.4% to 17%). No patients developed severe AKI necessitating renal replacement therapy. Patients with previous autologous or allogeneic stem cell transplantation, those requiring intensive care unit level care and with grade 3-4 CRS had a higher incidence of AKI. Most patients recovered, with kidney function returning to baseline within 30 days. We conclude that with early recognition and management of CAR-T complications, the incidence of AKI is low, the severity of injury is mild, and most patients recover kidney function within 30 days.

• Cytokine release syndrome (CRS) occurs at day 0 to day +5 in 90% of haploidentical peripheral blood stem cell transplant recipients. • Overall survival in our cohort was 58% at 2 years, because most CRS was mild. • Older patients and those who received radiation therapy are more prone to severe CRS. • Nonrelapse mortality was 38% at 6 months among patients with severe CRS. Inflammatory cytokines released by activated lymphocytes and innate cells in the context of cellular therapy can cause fever, vasodilatation, and end-organ damage, collectively known as cytokine release syndrome (CRS). CRS can occur after allogeneic blood or marrow transplantation, but is especially prevalent after HLA-haploidentical (haplo) peripheral blood transplantation (PBT). We reviewed charts of all patients who underwent haplo-PBT between October 1, 2013, and September 1, 2017 and graded CRS in these patients. A total of 146 consecutive patients who underwent related haplo-PBT were analyzed. CRS occurred in 130 patients (89%), with most cases of mild severity (grade 0 to 2). Severe CRS (grade 3 to 5) occurred in 25 patients (17%). In this group with severe CRS, 13 patients had encephalopathy, 12 required hemodialysis, and 11 were intubated. Death from the immediate complications of CRS occurred in 6 patients (24% of the severe CRS group and 4% of the entire haplo-PBT cohort). The cumulative probability of nonrelapse mortality (NRM) was 38% at 6 months for the patients with severe CRS and 8% (121 of 146) in patients without severe CRS. In conclusion, CRS occurs in nearly 90% of haplo-PBTs. Older haplo-PBT recipients (odds ratio [OR], 2.4; 95% confidence interval [CI],.83 to 6.75; P =.11) and those with a history of radiation therapy (OR, 3.85; 95% CI, 1.32 to 11.24; P =.01) are at increased risk of developing severe CRS. Although most recipients of haplo-PBT develop CRS, <20% experience severe complications. The development of severe CRS is associated with a significantly increased risk of NRM.

Highlights • CRS is a common, potentially life-threatening complication of CAR T cell therapy requiring close observation. • The first clinical sign of CRS is fever, which can progress to hypotension, hypoxia, and end-organ dysfunction. • In ALL, disease burden is a significant risk factor for severe CRS. • Administration of the anti-IL-6 receptor antagonist tocilizumab, with or without corticosteroids, is the mainstay of treatment. The optimal timing for intervention with tocilizumab is unknown. • Investigations are underway to identify novel approaches to prevent and abrogate CRS. Abstract Chimeric antigen receptor (CAR)-modified T cells (CAR-Ts) targeting CD19 have resulted in unprecedented durable remissions for patients with relapsed and refractory B cell malignancies. Cytokine release syndrome (CRS), resulting from rapid immune activation induced by CAR-Ts, is the most significant treatment-related toxicity. CRS initially manifests with fever and can progress to life-threatening capillary leak with hypoxia and hypotension. The clinical signs of CRS correlate with T cell activation and high levels of cytokines including IL-6. Tocilizumab, an anti-IL-6 receptor antagonist, is the standard for CRS management, but optimal timing of administration is unclear. The development of a supportive infrastructure by treatment centers is important to maintain safe administration as access expands. Collaborative efforts are underway to harmonize the definition and grading of CRS to allow for better interpretation of toxicities across CAR-T products and clinical trials and allow for informed management algorithms.

Highlights • Cytokine release syndrome (CRS) and neurotoxicity are common after immune effector cell (IEC) therapy. • Neurotoxicity is now termed IEC-associated neurotoxicity syndrome (ICANS). • A consensus grading system for CRS and ICANS has been developed by experts in the field. • The grading system is designed for IEC therapies in clinical trials and commercial use. • Standardized reporting through the Center for International Blood and Marrow Transplant Research will meet commercial Risk Evaluation and Mitigation Strategies requirements. ABSTRACT Chimeric antigen receptor (CAR) T cell therapy is rapidly emerging as one of the most promising therapies for hematologic malignancies. Two CAR T products were recently approved in the United States and Europe for the treatment ofpatients up to age 25years with relapsed or refractory B cell acute lymphoblastic leukemia and/or adults with large B cell lymphoma. Many more CAR T products, as well as other immunotherapies, including various immune cell- and bi-specific antibody-based approaches that function by activation of immune effector cells, are in clinical development for both hematologic and solid tumor malignancies. These therapies are associated with unique toxicities of cytokine release syndrome (CRS) and neurologic toxicity. The assessment and grading of these toxicities vary considerably across clinical trials and across institutions, making it difficult to compare the safety of different products and hindering the ability to develop optimal strategies for management of these toxicities. Moreover, some aspects of these grading systems can be challenging to implement across centers. Therefore, in an effort to harmonize the definitions and grading systems for CRS and neurotoxicity, experts from all aspects of the field met on June 20 and 21, 2018, at a meeting supported by the American Society for Transplantation and Cellular Therapy (ASTCT; formerly American Society for Blood and Marrow Transplantation, ASBMT) in Arlington, VA. Here we report the consensus recommendations of that group and propose new definitions and grading for CRS and neurotoxicity that are objective, easy to apply, and ultimately more accurately categorize the severity of these toxicities. The goal is to provide a uniform consensus grading system for CRS and neurotoxicity associated with immune effector cell therapies, for use across clinical trials and in the postapproval clinical setting.

T cell–replete post-transplant cyclophosphamide (PTCy)-based protocols have led to increasing use of haploidentical allogeneic hematopoietic cell transplantation (haploHCT). With this approach, bidirectional alloreactivity causing nonengraftment or severe graft-versus-host disease (GVHD) is no a longer major barrier to haploHCT. PTCy eliminates alloreactive lymphocytes but spares CD34 + stem cells and regulatory T lymphocytes, resulting in reliable hematopoietic recovery with relatively low incidence of GVHD. The immediate post-haploHCT course, usually before PTCy administration, is often complicated by cytokine release syndrome (CRS). The predictors of CRS and its effect on outcomes post-transplant have not been fully ascertained. We analyzed the outcomes of 66 patients who received haploHCT at our institution. Using published CRS criteria we identified 48 patients who developed CRS. In multivariate analysis peripheral blood grafts were significantly associated with grade ≥ 2 CRS, compared with bone marrow. Grade ≥ 2 CRS (compared with grade < 2) was not associated with differences in overall survival or nonrelapse mortality. Severe CRS was associated with a statistically nonsignificant trend toward higher incidences of grades III to IV acute GVHD, especially in the context of peripheral blood grafts. CRS is a common complication after T cell–replete peripheral blood haploHCT, but post-transplant survival outcomes may not be affected in those with severe CRS. [ABSTRACT FROM AUTHOR]

Two commercial chimeric antigen receptor (CAR) T cell therapies for CD19-expressing B cell malignancies, Kymriah and Yescarta, have recently been approved by the Food and Drug Administration. The administration of CAR T cells is a complex endeavor involving cell manufacture, tracking and shipping of apheresis products, and management of novel and severe toxicities. At Memorial Sloan Kettering Cancer Center, we have identified 8 essential tasks that define the CAR T cell workflow. In this review, we discuss practical aspects of CAR T cell program development, including clinical, administrative, and regulatory challenges for successful implementation. [ABSTRACT FROM AUTHOR]

Therapeutic T cell engineering has recently garnered widespread interest because of the success of CD19 chimeric antigen receptor (CAR) therapy. CARs are synthetic receptors for antigen that redirect the specificity and reprogram the function of the T cells in which they are genetically introduced. CARs targeting CD19, a cell surface molecule found in most leukemias and lymphomas, have yielded high remission rates in patients with chemorefractory, relapsed disease, including acute lymphoblastic leukemia, chronic lymphocytic leukemia, and non-Hodgkin lymphoma. The toxicities of this treatment include B cell aplasia, cytokine release syndrome (CRS), and neurotoxicity. Although reversible in most instances, these toxicities may require specific medical interventions, including transfer to intensive care to treat severe CRS. Guidelines for managing these toxicities are emerging. The recent report of a nonhuman primate model for CRS is poised to help advance the management of this syndrome. Finally, new engineering modalities, based on the use of targeted nucleases like CRISPR, may further enhance the efficacy and safety of CAR T cells. [ABSTRACT FROM AUTHOR]
