ABSTRACT
BACKGROUND: The expansion of preoperative immunochemotherapy has led to an increase in the number of patients with lung cancer receiving immune checkpoint inhibitors (ICIs). Therefore, oncologists should manage a variety of immune-related adverse events (irAEs). One of the rare, life-threatening, and recently proposed irAEs is cytokine release syndrome (CRS). Although the standard treatment of irAE is systemic administration of steroids, it has been suggested that tocilizumab may be an effective treatment option for CRS. CASE: This case describes a 69-year-old man with stage IIIA lung adenocarcinoma who received chemotherapy and nivolumab, which is an ICI, as neoadjuvant immunochemotherapy. After the first administration, the patient developed severe skin rash, fever, and arthralgia. We suspected irAEs and administered systemic steroids. However, fever and arthralgia did not improve, although the skin rash disappeared. These were also significant challenges for surgery. Noting the elevated levels of inflammatory cytokines, we consulted a rheumatologist. Finally, we decided to terminate neoadjuvant therapy after one cycle and administer tocilizumab. Tocilizumab dramatically improved the patient's symptoms and allowed him to undergo radical surgery. Pathological findings revealed that the patient achieved a major pathological response. CONCLUSION: This indicates the potential effectiveness of early tocilizumab administration for ICI-induced CRS, even in mild cases.

BACKGROUND CRS (cytokine release syndrome) is a massive activation of the inflammatory system characterized by a supra-physiological rate of inflammatory cytokines. The interleukin 6 cytokine plays a central role in CRS. The main clinical sign of CRS is fever, but CRS can lead to multiple organ failure in severe cases. CRS is usually described in sepsis, more recently in SARS COV-2 infection, and in chimeric antigen receptor T-cell therapy. However, it can also be associated with immune checkpoint inhibitors (ICIs), which is infrequently described. ICI have growing indications and can lead to CRS by causing an uncontrolled activation of the immune system. There are currently no treatment guidelines for ICI-induced CRS. CASE REPORT We report a rare case of grade 3 CRS induced by nivolumab associated with 5-fluorouracil and oxaliplatin for gastric cancer. The patient was 65-year-old man with an adenocarcinoma of the cardia. CRS developed during the tenth course of treatment and was characterized by fever, hypotension requiring vasopressors, hypoxemia, acute kidney injury, and thrombopenia. The patient was transferred quickly to the Intensive Care Unit. He was treated for suspected sepsis, but it was ruled out after multiple laboratory examinations. There was rapid resolution after infusion of hydrocortisone. CONCLUSIONS The use of ICIs is expanding. Nivolumab-induced CRS is rarely described but can be severe and lead to multiple organ dysfunction; therefore, intensive care practitioners should be informed about this adverse effect. More studies are needed to better understand this condition and establish treatment guidelines.

BACKGROUND: Tarlatamab, a bispecific T-cell engager immunotherapy targeting delta-like ligand 3 and CD3, showed promising antitumor activity in a phase 1 trial in patients with previously treated small-cell lung cancer. METHODS: In this phase 2 trial, we evaluated the antitumor activity and safety of tarlatamab, administered intravenously every 2 weeks at a dose of 10 mg or 100 mg, in patients with previously treated small-cell lung cancer. The primary end point was objective response (complete or partial response), as assessed by blinded independent central review according to the Response Evaluation Criteria in Solid Tumors, version 1.1. RESULTS: Overall, 220 patients received tarlatamab; patients had previously received a median of two lines of treatment. Among patients evaluated for antitumor activity and survival, the median follow-up was 10.6 months in the 10-mg group and 10.3 months in the 100-mg group. An objective response occurred in 40% (97.5% confidence interval [CI], 29 to 52) of the patients in the 10-mg group and in 32% (97.5% CI, 21 to 44) of those in the 100-mg group. Among patients with an objective response, the duration of response was at least 6 months in 59% (40 of 68 patients). Objective responses at the time of data cutoff were ongoing in 22 of 40 patients (55%) in the 10-mg group and in 16 of 28 patients (57%) in the 100-mg group. The median progression-free survival was 4.9 months (95% CI, 2.9 to 6.7) in the 10-mg group and 3.9 months (95% CI, 2.6 to 4.4) in the 100-mg group; the estimates of overall survival at 9 months were 68% and 66% of patients, respectively. The most common adverse events were cytokine-release syndrome (in 51% of the patients in the 10-mg group and in 61% of those in the 100-mg group), decreased appetite (in 29% and 44%, respectively), and pyrexia (in 35% and 33%). Cytokine-release syndrome occurred primarily during treatment cycle 1, and events in most of the patients were grade 1 or 2 in severity. Grade 3 cytokine-release syndrome occurred less frequently in the 10-mg group (in 1% of the patients) than in the 100-mg group (in 6%). A low percentage of patients (3%) discontinued tarlatamab because of treatment-related adverse events. CONCLUSIONS: Tarlatamab, administered as a 10-mg dose every 2 weeks, showed antitumor activity with durable objective responses and promising survival outcomes in patients with previously treated small-cell lung cancer. No new safety signals were identified. (Funded by Amgen; DeLLphi-301 ClinicalTrials.gov number, NCT05060016.).

OBJECTIVE: This dose-escalation part of an ongoing Phase I study assessed the tolerability, safety and pharmacokinetics of mosunetuzumab in Japanese patients with relapsed/refractory B-cell non-Hodgkin lymphoma (NHL). METHODS: Mosunetuzumab was administered intravenously, with step-up dosing in a 3 + 3 design, on Days 1, 8 and 15 of Cycle 1, and Day 1 of each subsequent 21-day cycle for up to 17 cycles to patients across five cohorts with different target doses (2.8, 6.0, 13.5, 27.0 or 60.0 mg). RESULTS: As of 5 July 2022, 23 patients had received mosunetuzumab. The median patient age was 63.0 years, 56.5% of patients were male, and 69.6% of patients had diffuse large B-cell lymphoma, 17.4% had transformed follicular lymphoma (FL) and 13.0% had FL. The median number of prior lines of therapy was 4. Mosunetuzumab was well tolerated and there were no deaths. The most common adverse events (any grade) were neutropenia/neutrophil count decreased (47.8%) and cytokine release syndrome (34.8%). Most cytokine release syndrome events were Grade 1/2 (one Grade 3), and most occurred within 24 hours of the first dose of mosunetuzumab. The apparent half-life of mosunetuzumab was 4.1-5.0 days. Two patients achieved a complete response, and 11 patients achieved a partial response. CONCLUSIONS: This study demonstrated that mosunetuzumab has an acceptable safety profile and antitumor activity in Japanese patients with relapsed/refractory B-cell NHL. The recommended Phase II dose of 1.0/2.0/60.0/60.0/30.0 mg was tolerable and there were no new or different safety signals compared with the global Phase I study.

BACKGROUND: Cytokine release syndrome (CRS) is a common adverse event of CAR T cell or bispecific antibody (bsAb) therapy. Anti-IL6/IL6R drugs are used in the management of auto-immune diseases. Some reports showed increased risk of bacterial infection in this context. In onco-hematology, there are few data about the occurrence of infection after administration of an anti-IL6/IL6R for CRS. METHODS: We retrospectively reviewed all consecutive patients treated in Gustave Roussy Cancer Campus between 2018 and 2021, who received anti-IL6/IL6R for CRS due to bsAb in phase I clinical trials or adoptive cellular therapy (ACT). We constituted a control group including all the patients treated in the same clinical trials or standard of care ACT, naïve of anti-IL6/IL6R. RESULTS: Fifty-two patients have been included. In the anti-IL6/IL6R group (n = 26), five patients developed a grade 2 to 5 infection within a month after anti-IL6/IL6R treatment, including two grade 5 infections. In the control group (n = 26), only one patient had a grade 3 infection. The two patients who had grade 5 infections were treated for diffuse large B cell lymphoma (DLBCL), one with bsAb and the other with CAR T cell. Fifty percent (3/6) of DLBCL patients who received an anti-IL6/IL6R presented an infection, one of which was a grade 5. In solid tumor patients treated with bsAb and anti-IL6/IL6R, only one patient (/9, 11%) developed a grade 2 viral infection. CONCLUSION: It seems that the use of anti-IL6/IL6R in CRS secondary to bsAb administration in solid tumors patients does not significantly increase the risk of infection, as opposed to DLBCL patients where secondary infection might be a concern.

Cytokine release syndrome (CRS) is a severe and life-threatening toxicity typically reported in chimeric antigen receptor T cell therapy and is rarely reported in immune checkpoint inhibitor (ICI) therapy. This study reports the case of a 75-year-old Japanese woman who received nivolumab plus ipilimumab therapy for the postoperative recurrence of non-small cell lung cancer. She was admitted to our hospital with fever, hypotension, hepatic disorder, and thrombocytopenia. We observed slight skin rashes on her neck on admission, which spread rapidly across her body within a few days. We diagnosed CRS complicated by severe rashes. CRS symptoms were resolved with corticosteroid therapy, and did not recur thereafter. CRS is a rare, but important, immune-related adverse event associated with ICI therapy.

Immune checkpoint inhibitors, a type of immunotherapy, have demonstrated optimal treatment efficacy in inducing durable antitumor responses in various cancers. Cytokine-release syndrome is a rare immune-related adverse event induced by immune checkpoint inhibitors. In our case, a patient with hypopharyngeal squamous cell carcinoma received toripalimab combined with chemotherapy. On the fourth day post treatment, the patient developed fever and hypotension. Laboratory examination indicated myelosuppression, acute kidney injury and disseminated intravascular coagulation. Meanwhile, serum cytokine levels of IL-6, IL-8, IL-10, IL-1ß, IFN-γ and the level of hypersensitive C-reactive protein were markedly elevated. The patient was diagnosed with cytokine release syndrome, which progressed rapidly and led to the patient's demise on the fifth day post treatment.
Immune checkpoint inhibitors (ICIs) have shown revolutionary efficacy in the treatment of multiple cancers. Cytokine-release syndrome (CRS) is a common and lethally adverse event of chimeric antigen receptor T-cell therapy; however, this adverse effect is rare in ICI therapy. Presently, while ICI-associated CRS is reported almost exclusively in case reports, fatal outcomes are rarely observed. A patient with hypopharyngeal squamous cell carcinoma received toripalimab combined with chemotherapy. On the fourth day post treatment, the patient developed CRS, which progressed rapidly, and the patient died on the fifth day post treatment.

BACKGROUND: G protein-coupled receptor, family C, group 5, member D (GPRC5D) is an orphan receptor expressed in malignant plasma cells. Talquetamab, a bispecific antibody against CD3 and GPRC5D, redirects T cells to mediate killing of GPRC5D-expressing myeloma cells. METHODS: In a phase 1 study, we evaluated talquetamab administered intravenously weekly or every other week (in doses from 0.5 to 180 µg per kilogram of body weight) or subcutaneously weekly, every other week, or monthly (5 to 1600 µg per kilogram) in patients who had heavily pretreated relapsed or refractory multiple myeloma that had progressed with established therapies (a median of six previous lines of therapy) or who could not receive these therapies without unacceptable side effects. The primary end points - the frequency and type of dose-limiting toxic effects (study part 1 only), adverse events, and laboratory abnormalities - were assessed in order to select the recommended doses for a phase 2 study. RESULTS: At the data-cutoff date, 232 patients had received talquetamab (102 intravenously and 130 subcutaneously). At the two subcutaneous doses recommended for a phase 2 study (405 µg per kilogram weekly [30 patients] and 800 µg per kilogram every other week [44 patients]), common adverse events were cytokine release syndrome (in 77% and 80% of the patients, respectively), skin-related events (in 67% and 70%), and dysgeusia (in 63% and 57%); all but one cytokine release syndrome event were of grade 1 or 2. One dose-limiting toxic effect of grade 3 rash was reported in a patient who had received talquetamab at the 800-µg dose level. At median follow-ups of 11.7 months (in patients who had received talquetamab at the 405-µg dose level) and 4.2 months (in those who had received it at the 800-µg dose level), the percentages of patients with a response were 70% (95% confidence interval [CI], 51 to 85) and 64% (95% CI, 48 to 78), respectively. The median duration of response was 10.2 months and 7.8 months, respectively. CONCLUSIONS: Cytokine release syndrome, skin-related events, and dysgeusia were common with talquetamab treatment but were primarily low-grade. Talquetamab induced a substantial response among patients with heavily pretreated relapsed or refractory multiple myeloma.

BACKGROUND: The prognosis for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) is poor. Glofitamab is a bispecific antibody that recruits T cells to tumor cells. METHODS: In the phase 2 part of a phase 1-2 study, we enrolled patients with relapsed or refractory DLBCL who had received at least two lines of therapy previously. Patients received pretreatment with obinutuzumab to mitigate cytokine release syndrome, followed by fixed-duration glofitamab monotherapy (12 cycles total). The primary end point was complete response according to assessment by an independent review committee. Key secondary end points included duration of response, survival, and safety. RESULTS: Of the 155 patients who were enrolled, 154 received at least one dose of any study treatment (obinutuzumab or glofitamab). At a median follow-up of 12.6 months, 39% (95% confidence interval [CI], 32 to 48) of the patients had a complete response according to independent review. Results were consistent among the 52 patients who had previously received chimeric antigen receptor T-cell therapy (35% of whom had a complete response). The median time to a complete response was 42 days (95% CI, 42 to 44). The majority (78%) of complete responses were ongoing at 12 months. The 12-month progression-free survival was 37% (95% CI, 28 to 46). Discontinuation of glofitamab due to adverse events occurred in 9% of the patients. The most common adverse event was cytokine release syndrome (in 63% of the patients). Adverse events of grade 3 or higher occurred in 62% of the patients, with grade 3 or higher cytokine release syndrome in 4% and grade 3 or higher neurologic events in 3%. CONCLUSIONS: Glofitamab therapy was effective for DLBCL. More than half the patients had an adverse event of grade 3 or 4. (Funded by F. Hoffmann-La Roche; ClinicalTrials.gov number, NCT03075696.).

The autologous anti-CD19 chimeric antigen receptor (CAR) T-cell product, lisocabtagene maraleucel (liso-cel), is administered at equal target doses of CD8+ and CD4+ CAR+ T cells. This analysis assessed safety and efficacy of liso-cel in Japanese patients with relapsed or refractory (R/R) aggressive large B-cell lymphoma (LBCL) in Cohort 3 of TRANSCEND WORLD (NCT03484702). Liso-cel (100 × 106 total CAR+ T cells) was administered 2-7 days after lymphodepletion. The primary efficacy endpoint was objective response rate (ORR; Lugano 2014 criteria) assessed by an independent review committee. Fourteen patients were enrolled; 10 received liso-cel infusion (median time to liso-cel availability, 23 days) and were evaluable at data cutoff (median follow-up, 12.5 months). Grade ≥ 3 treatment-emergent adverse events were neutropenia (90%), leukopenia (80%), anemia (70%), and thrombocytopenia (70%). All-grade cytokine release syndrome (CRS) was observed in 50% of patients, though no grade ≥3 CRS events were reported. Grade 1 neurological events occurred in 1 patient but were resolved without any intervention. Prolonged cytopenia (grade ≥ 3 at day 29) was reported for 60% of patients. The ORR was 70%, and complete response rate was 50%. The median duration of response was 9.1 months (95% confidence interval [CI], 2.1-not reached), and overall survival was 14.7 months (95% CI, 1.7-not reached). One patient diagnosed with central nervous system involvement after screening but before liso-cel infusion, responded to liso-cel. Liso-cel demonstrated meaningful efficacy and a manageable safety profile in Japanese patients with R/R LBCL.

Cytokine release syndrome (CRS) is a phenomenon of immune hyperactivation described in the setting of immunotherapy. Unlike other immune-related adverse events, CRS triggered by immune checkpoint inhibitors (ICIs) is not well described. The clinical characteristics and course of 25 patients with ICI-induced CRS from 2 tertiary hospitals were abstracted retrospectively from the medical records and analyzed. CRS events were confirmed by 2 independent reviewers and graded using the Lee et al. scale. The median duration of CRS was 15.0 days (Q1; Q3 6.3; 29.8) and 10 (40.0%) had multiple episodes of CRS flares. Comparing the clinical factors and biomarkers in Grades 1-2 and 3-5 CRS, we found that patients with Grades 3-5 CRS had following: (i) had longer time to fever onset [25.0 days (Q1; Q3 13.0; 136.5) vs. 3.0 days (Q1; Q3 0.0; 18.0), p=0.027]; (ii) more cardiovascular (p=0.002), neurologic (p=0.001), pulmonary (p=0.044) and rheumatic (p=0.037) involvement; (iii) lower platelet count (p=0.041) and higher urea (p=0.041) at presentation compared to patients with Grades 1-2 CRS. 7 patients (28.0%) with Grades 1-2 CRS were rechallenged using ICIs without event. 9 patients (36.0%) were treated with pulse methylprednisolone and 6 patients (24.0%) were treated with tocilizumab. Despite this, 3 patients (50%) who received tocilizumab had fatal (Grade 5) outcomes from ICI-induced CRS. Longer time to fever onset, lower platelet count and higher urea at presentation were associated with Grade 3-5 CRS. These parameters may be used to predict which patients are likely to develop severe CRS.

Cytokine release syndrome (CRS) is an undesired immune reaction that may cause dangerous side effects after the administration of novel biological therapies. In vitro cytokine release assays (CRA) are used for preclinical safety assessment prior to first-in-man dose administration of therapeutic monoclonal antibodies (mAbs). A variety of CRA platforms has been developed where the analysis of secreted cytokines is performed. Analysis of T cell activation markers is not performed routinely in CRA platforms and few studies have described intracellular cytokine levels after stimulation with therapeutic mAbs. In the present study, we performed a CRA using intracellular cytokine staining and assessment of extracellular T cell activation markers by flow cytometry. We used commercially available reference mAbs for the stimulation of peripheral blood mononuclear cells (PBMCs). We found that stimulation using solid phase (SP) dry coating with two different CD28 antibodies and muromonab-CD3 increased the percentage of IFN-É£ + CD4+ and CD8+ T cells as well as of CD3-CD56+ NK cells compared to stimulation with antibodies in aqueous phase (AP). Expression of the T cell activation markers CD25 and CD69 on CD4+ and CD8+ T cells was also increased upon SP muromonab-CD3 stimulation. Using multiplex cytokine assessment, we showed that stimulation in AP using ANC28.1, CD28.2 and muromonab-CD3 led to an increase of IFN-É£, GM-CSF, TNF-α, and IL-2 secretion. Stimulation of PBMCs preincubated at high-density culture led to an increase in IFN-É£ production but not in the expression of activation markers compared to low-density culture. Our findings demonstrated that flow cytometry analyses for assessing relevant T cell and NK cell markers may be used as a supplement to multiplex cytokine analysis in CRAs. The approach may be a valuable addition that enables a more precise description of the mechanisms leading to CRS.

Systemic hyperinflammation is a hallmark of severe coronavirus disease-2019 (COVID-19). Tocilizumab (TCZ) (an interleukin-6 receptor blocker) therapy is currently used as an anti-inflammatory intervention alongside corticosteroids to modulate the hyperinflammatory response (cytokine storm) in hospitalized patients with severe COVID-19 to prevent mortality. There is, however, a wide uncertainty about its pros and cons in patients with COVID-19, particularly, its possible immunosuppressive effect is of serious concern for the clinicians. The present study aimed to report response of a cohort of severely-ill hospitalized COVID-19 pneumonia patients who were treated with tocilizumab after the initial corticosteroids therapy failed to improve the patients' clinical condition. This was a single-arm retrospective study of 100 severely-ill COVID-19 pneumonia patients who were admitted to the specialized COVID-19 units of Mayo Hospital, Lahore, Pakistan from March 12, 2020, to May 25, 2021. These COVID-19 patients had progressed to cytokine storm with persistent hypoxia, associated with pneumonia, and markedly elevated serum levels of inflammatory biomarkers including C-reactive protein (CRP), D-dimer, and ferritin. All the patients had received two separate doses of intravenous 400 mg (4 mg/kg) tocilizumab with an 8-hour interval alongside standard COVID-19 care which includes corticosteroid, antibiotics, and anticoagulants. Following tocilizumab intervention, 75 (75.0%) patients showed clinical improvement, continued to recover, and were safely discharged from the hospital, while in 25 (25.0%) patients, TCZ failed to prevent clinical deterioration, and patients eventually died in the hospital. Amongst the 25 (25.0%) deaths, 8 (32.0%) patients had a single comorbidity, while 9 (36.0%) had two or more comorbidities. The median IQR age for survivors was 57.0 (50.0, 60.0) years, and non-survivors was 60.0 (55.0, 70.0) years; and the period of hospitalization was 25 (20, 40) days and 20 (14, 34) days, respectively. Tocilizumab treatment improved serum inflammatory biomarker levels including CRP, D-dimer, and ferritin, by almost a similar magnitude in both survivors and non-survivors. Development of secondary infections were reported in 25 (25.0%) patients, including 21% patients with bacterial (Pseudomonas, Klebsiella, Acinetobacter) and 4% with fungal (Aspergillus) infection. The emergence of secondary infection was higher in patients who died (72.0%) as compared to those who survived (28.0%). In conclusion: in low- and middle-income countries in the presence of limited therapeutic options, a timely intervention of TCZ alongside corticosteroids may be a suitable anti-inflammatory therapy for severely-ill hospitalized COVID-19 pneumonia patients to prevent mortality. However, patients must be closely monitored for secondary bacterial/fungal infections. Early diagnosis and management of secondary infection can reduce morbidity and mortality.

Therapeutics that impair the innate immune responses of the liver during the inflammatory cytokine storm like that occurring in COVID-19 are greatly needed. Much interest is currently directed toward Janus kinase (JAK) inhibitors as potential candidates to mitigate this life-threatening complication. Accordingly, this study investigated the influence of the novel JAK inhibitor ruxolitinib (RXB) on concanavalin A (Con A)-induced hepatitis and systemic hyperinflammation in mice to simulate the context occurring in COVID-19 patients. Mice were orally treated with RXB (75 and 150 mg/kg) 2 h prior to the intravenous administration of Con A (20 mg/kg) for a period of 12 h. The results showed that RXB pretreatments were efficient in abrogating Con A-instigated hepatocellular injury (ALT, AST, LDH), necrosis (histopathology), apoptosis (cleaved caspase-3) and nuclear proliferation due to damage (PCNA). The protective mechanism of RXB were attributed to i) prevention of Con A-enhanced hepatic production and systemic release of the proinflammatory cytokines TNF-α, IFN-γ and IL-17A, which coincided with decreasing infiltration of immune cells (monocytes, neutrophils), ii) reducing Con A-induced hepatic overexpression of IL-1ß and CD98 alongside NF-κB activation, and iii) lessening Con A-induced consumption of GSH and GSH peroxidase and generation of oxidative stress products (MDA, 4-HNE, NOx) in the liver. In summary, JAK inhibition by RXB led to eminent protection of the liver against Con A-deleterious manifestations primarily via curbing the inflammatory cytokine storm driven by TNF-α, IFN-γ and IL-17A.

OBJECTIVES: To report the epidemiology, treatments, and outcomes of adult patients admitted to the ICU after cytokine release syndrome or immune effector cell-associated neurotoxicity syndrome. DESIGN: Retrospective cohort study. SETTING: Nine centers across the U.S. part of the chimeric antigen receptor-ICU initiative. PATIENTS: Adult patients treated with chimeric antigen receptor T-cell therapy who required ICU admission between November 2017 and May 2019. INTERVENTIONS: Demographics, toxicities, specific interventions, and outcomes were collected. RESULTS: One-hundred five patients treated with axicabtagene ciloleucel required ICU admission for cytokine release syndrome or immune effector cell-associated neurotoxicity syndrome during the study period. At the time of ICU admission, the majority of patients had grade 3-4 toxicities (66.7%); 15.2% had grade 3-4 cytokine release syndrome and 64% grade 3-4 immune effector cell-associated neurotoxicity syndrome. During ICU stay, cytokine release syndrome was observed in 77.1% patients and immune effector cell-associated neurotoxicity syndrome in 84.8% of patients; 61.9% patients experienced both toxicities. Seventy-nine percent of patients developed greater than or equal to grade 3 toxicities during ICU stay, however, need for vasopressors (18.1%), mechanical ventilation (10.5%), and dialysis (2.9%) was uncommon. Immune Effector Cell-Associated Encephalopathy score less than 3 (69.7%), seizures (20.2%), status epilepticus (5.7%), motor deficits (12.4%), and cerebral edema (7.9%) were more prevalent. ICU mortality was 8.6%, with only three deaths related to cytokine release syndrome or immune effector cell-associated neurotoxicity syndrome. Median overall survival time was 10.4 months (95% CI, 6.64-not available mo). Toxicity grade or organ support had no impact on overall survival; higher cumulative corticosteroid doses were associated to decreased overall and progression-free survival. CONCLUSIONS: This is the first study to describe a multicenter cohort of patients requiring ICU admission with cytokine release syndrome or immune effector cell-associated neurotoxicity syndrome after chimeric antigen receptor T-cell therapy. Despite severe toxicities, organ support and in-hospital mortality were low in this patient population.

BACKGROUND: Neurotoxicity is one of the dangerous complications of chimeric antigen receptor (CAR) T-cell therapy, while its pathophysiology remains to be fully understood. Motor weakness not associated with central nervous system (CNS) toxicity has rarely been reported after CAR T-cell therapy. CASE REPORT: A 42-year-old female with a refractory diffuse large B-cell lymphoma received tisagenlecleucel (tisa-cel) and developed cytokine release syndrome (CRS) on day 3. She was treated with tocilizumab and methylprednisolone, which resolved CRS promptly. On day 7, motor weakness in lower extremities appeared, and she gradually became unable to walk without showing any other symptoms attributed to CNS disturbances. Whereas dexamethasone and tocilizumab were ineffective, neuropathy improved after high dose chemotherapy followed by autologous stem cell transplantation. Nerve conduction study (NCS) in lower extremities showed a decline in compound muscle action potential amplitude along with worsening of motor weakness, which was restored after improvement of symptoms. Based on symptoms and NCS, her motor weakness was thought to be due to disturbance in peripheral nerves. CONCLUSION: This study reports a patient who developed severe motor weakness due to disturbance in peripheral nerves after tisa-cel therapy. Neurotoxicity of non-CNS origin should also be noted in CAR T-cell therapy.

Axicabtagene ciloleucel (axi-cel) is an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy approved for relapsed or refractory large B-cell lymphoma (R/R LBCL). To reduce axi-cel-related toxicity, several exploratory safety management cohorts were added to ZUMA-1 (NCT02348216), the pivotal phase 1/2 study of axi-cel in refractory LBCL. Cohort 4 evaluated the rates and severity of cytokine release syndrome (CRS) and neurologic events (NEs) with earlier corticosteroid and tocilizumab use. Primary endpoints were incidence and severity of CRS and NEs. Patients received 2 × 106 anti-CD19 CAR T cells/kg after conditioning chemotherapy. Forty-one patients received axi-cel. Incidences of any-grade CRS and NEs were 93% and 61%, respectively (grade ≥ 3, 2% and 17%). There was no grade 4 or 5 CRS or NE. Despite earlier dosing, the cumulative cortisone-equivalent corticosteroid dose in patients requiring corticosteroid therapy was lower than that reported in the pivotal ZUMA-1 cohorts. With a median follow-up of 14·8 months, objective and complete response rates were 73% and 51%, respectively, and 51% of treated patients were in ongoing response. Earlier and measured use of corticosteroids and/or tocilizumab has the potential to reduce the incidence of grade ≥ 3 CRS and NEs in patients with R/R LBCL receiving axi-cel.

BACKGROUND: Uveal melanoma is a disease that is distinct from cutaneous melanoma, with a low tumor mutational burden and a 1-year overall survival of approximately 50% in patients with metastatic uveal melanoma. Data showing a proven overall survival benefit with a systemic treatment are lacking. Tebentafusp is a bispecific protein consisting of an affinity-enhanced T-cell receptor fused to an anti-CD3 effector that can redirect T cells to target glycoprotein 100-positive cells. METHODS: In this open-label, phase 3 trial, we randomly assigned previously untreated HLA-A*02:01-positive patients with metastatic uveal melanoma in a 2:1 ratio to receive tebentafusp (tebentafusp group) or the investigator's choice of therapy with single-agent pembrolizumab, ipilimumab, or dacarbazine (control group), stratified according to the lactate dehydrogenase level. The primary end point was overall survival. RESULTS: A total of 378 patients were randomly assigned to either the tebentafusp group (252 patients) or the control group (126 patients). Overall survival at 1 year was 73% in the tebentafusp group and 59% in the control group (hazard ratio for death, 0.51; 95% confidence interval [CI], 0.37 to 0.71; P<0.001) in the intention-to-treat population. Progression-free survival was also significantly higher in the tebentafusp group than in the control group (31% vs. 19% at 6 months; hazard ratio for disease progression or death, 0.73; 95% CI, 0.58 to 0.94; P = 0.01). The most common treatment-related adverse events in the tebentafusp group were cytokine-mediated events (due to T-cell activation) and skin-related events (due to glycoprotein 100-positive melanocytes), including rash (83%), pyrexia (76%), and pruritus (69%). These adverse events decreased in incidence and severity after the first three or four doses and infrequently led to discontinuation of the trial treatment (2%). No treatment-related deaths were reported. CONCLUSIONS: Treatment with tebentafusp resulted in longer overall survival than the control therapy among previously untreated patients with metastatic uveal melanoma.

We describe the first case of hyperacute reversible encephalopathy following COVID-19 vaccination. A patient presented with acute onset encephalopathy, mainly characterized by agitation and confusion, rapidly responsive to high dosage steroid therapy and complete remission within 3 days from onset. The clinical manifestation was related with systemic and CSF cytokine hyperproduction, responsive to steroid therapy. Although the occurrence of encephalopathy after vaccination may be just a casual temporal association, we speculate that the cytokine-storm could be the result of an excessive innate immune response against the vaccine, in a predisposed patient susceptible to autoimmunity.

Cytokine release syndrome (CRS) is a well-described immune-related adverse event following chimeric antigen receptor T-cell therapy, but has rarely been reported following anti-programmed death ligand-1 therapy. We report the case of a 55-year-old man with metastatic lung adenocarcinoma who presented with fever, chills and hypotension. Initial labs were notable for highly elevated serum ferritin levels and mildly elevated triglyceride levels. He was ultimately diagnosed with pembrolizumab-induced CRS complicated by multiorgan failure. The patient was treated with steroids and tocilizumab with normalization of inflammatory markers and resolution of renal failure. This case not only highlights the importance of considering CRS in patients who have developed multiorgan failure after immune checkpoint inhibitor therapy, but also demonstrates clinical similarities between CRS and other hyperinflammatory states such as hemophagocytic lymphohistiocytosis.
