Grading and management of cytokine release syndrome in patients treated with tisagenlecleucel in the JULIET trial.

ABSTRACT: Chimeric antigen receptor T-cell (CAR-T) therapy yields durable responses in patients with relapsed/refractory diffuse large B-cell lymphoma (r/r DLBCL). Cytokine release syndrome (CRS) is a CAR-T therapy-related adverse event. To date, clinical trials of different CAR-T products have not been aligned on CRS grading scales and management algorithms. We assessed concordance between the Penn, Lee, and American Society for Transplantation and Cellular Therapy (ASTCT) grading systems by retrospectively regrading CRS events in the JULIET (A Phase 2, Single Arm, Multicenter Trial to Determine the Efficacy and Safety of CTL019 in Adult Patients With Relapsed or Refractory DLBCL) trial. Four medical experts with experience treating patients with 3 different CAR-T products independently regraded individual patient-level CRS events from the phase 2, global, pivotal JULIET trial (#NCT02445248). As of 8 December 2017, a total of 111 patients with r/r DLBCL underwent infusion with tisagenlecleucel. Sixty-four patients had CRS events graded per the Penn scale; on retrospective review, 63 and 61 patients had CRS events regraded per the Lee and ASTCT criteria, respectively. The Lee scale yielded concordance for 39, lower grade for 20, and higher grade for 5 events compared with the Penn scale. The ASTCT criteria provided concordance for 37, lower grade for 23, and higher grade for 4 events compared with the Penn scale. Sixteen (14%) of 111 patients in the JULIET trial received tocilizumab, all for severe events (Penn grade 3/4 CRS). This study is the first to assess concordance between 3 CRS grading scales using the same patient data set and to compare tocilizumab use according to the Lee scale in the JULIET trial and the ZUMA-1 (Long-Term Safety and Activity of Axicabtagene Ciloleucel in Refractory Large B-Cell Lymphoma) trial. This analysis describes key differences between grading scales and may inform CRS management practices.

Project description:Background and purposeNeurological manifestations in coronavirus disease (COVID)-2019 may adversely affect clinical outcomes. Severe COVID-19 and uremia are risk factors for neurological complications. However, the lack of insight into their pathogenesis, particularly with respect to the role of the cytokine release syndrome (CRS), is currently hampering effective therapeutic interventions. The aims of this study were to describe the neurological manifestations of patients with COVID-19 and to gain pathophysiological insights with respect to CRS.MethodsIn this longitudinal study, we performed extensive clinical, laboratory and imaging phenotyping in five patients admitted to our renal unit.ResultsNeurological presentation included confusion, tremor, cerebellar ataxia, behavioral alterations, aphasia, pyramidal syndrome, coma, cranial nerve palsy, dysautonomia, and central hypothyroidism. Notably, neurological disturbances were accompanied by laboratory evidence of CRS. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was undetectable in the cerebrospinal fluid (CSF). Hyperalbuminorrachia and increased levels of the astroglial protein S100B were suggestive of blood-brain barrier (BBB) dysfunction. Brain magnetic resonance imaging findings comprised evidence of acute leukoencephalitis (n = 3, one of whom had a hemorrhagic form), cytotoxic edema mimicking ischaemic stroke (n = 1), or normal results (n = 2). Treatment with corticosteroids and/or intravenous immunoglobulins was attempted, resulting in rapid recovery from neurological disturbances in two cases. SARS-CoV2 was undetectable in 88 of the 90 patients with COVID-19 who underwent Reverse Transcription-PCR testing of CSF.ConclusionsPatients with COVID-19 can develop neurological manifestations that share clinical, laboratory and imaging similarities with those of chimeric antigen receptor T-cell-related encephalopathy. The pathophysiological underpinnings appear to involve CRS, endothelial activation, BBB dysfunction, and immune-mediated mechanisms.
