Zusammenfassung CRS und ICANS als Nebenwirkung von CAR-T-Zellen Das Cytokine-Release-Syndrome (CRS) ist die häufigste Nebenwirkung einer CAR-T-Zell-Therapie und kann von leichtem Fieber bis zu einem Multiorganversagen führen. Pathophysiologisch kommt es beim CRS zu einem Zytokinsturm und trotz einer Therapie mit Tocilizumab sind refraktäre und tödliche Verläufe beschrieben. Die Symptome des Immune-Effector-Cell-associated-Neurotoxicity-Syndrome (ICANS) variieren von leichter Desorientiertheit bis zum lebensbedrohlichen Hirnödem. Die Pathophysiologie und Therapie des ICANS sind noch nicht ausreichend erforscht. Die Differenzialdiagnosen von CRS und ICANS sind komplex und umfassen neben Infektionen und Sepsis unter anderem auch eine Toxizität der vorhergehenden Therapie, ein Tumorlysesyndrom und nicht zuletzt einen Progress der Grunderkrankung. Ein klinischer oder laborchemischer Parameter zum sicheren Beweis oder Ausschluss eines CRS oder ICANS gibt es zum heutigen Zeitpunkt nicht. Intensivmedizinische Relevanz und potenzielle Entwicklungen der CAR-T-Zell-Therapie Erste Auswertungen von Real-world-Daten deuten auf eine höhere Rate an schweren Nebenwirkungen im Rahmen der CAR-T-Zell-Therapie als in den Zulassungsstudien hin. Für die Indikation r/r-DLBCL könnten schätzungsweise bis zu maximal 300 Patienten pro Jahr in Deutschland eine intensivmedizinische Betreuung im Rahmen der CAR-T-Zell-Therapie benötigen. Studien mit wesentlich häufigeren soliden Tumoren könnten die Patientenzahl drastisch erhöhen. Therapieziel bei CAR-T-Zell-Patienten und Entscheidungen bei Therapiezieländerung Aufgrund des neuen Therapiekonzepts kann ein Konflikt zwischen bislang palliativem Patientenkollektiv und nun möglicherweise langfristigen Remissionen entstehen. Eine frühzeitige Aufklärung über potenziell lebensbedrohliche Nebenwirkungen im Rahmen der Therapie und eine interdisziplinäre Besprechung der Therapieziele mit den Patienten ist entscheidend.

Chimeric antigen receptor T (CART) cell therapy is highly effective for relapsed/refractory hematologic malignancy [1,2]; however, cytokine release syndrome (CRS) and neurotoxicity are observed in up to 77% of patients [3]. In large case series, the most common presentations of neurotoxicity were encephalopathy (57%), headache (42%), tremor (38%) and aphasia (35%). CART mediated spinal cord toxicity is not well characterized. Structural neurologic damage (stroke and intracranial hemorrhage) was only observed in 1-2% and seizures were seen in 1%-8% of cases [3, 4]. Neuroimaging findings in patients with neurotoxicity are rare and not specific.

Abstract Chimeric antigen receptor (CAR) T-cell therapies have demonstrated high response rates in patients with relapsed/refractory large B-cell lymphoma (LBCL); however, these therapies are associated with 2 CAR T cell–specific potentially severe adverse events (AEs): cytokine release syndrome (CRS) and neurological events (NEs). This study estimated the management costs associated with CRS/NEs among patients with relapsed/refractory LBCL using data from the pivotal TRANSCEND NHL 001 trial of lisocabtagene maraleucel, an investigational CD19-directed defined composition CAR T-cell product with a 4-1BB costimulation domain administered at equal target doses of CD8+ and CD4+ CAR+ T cells. This retrospective analysis of patients from TRANSCEND with prospectively identified CRS and/or NE episodes examined relevant trial-observed health care resource utilization (HCRU) associated with toxicity management based on the severity of the event from the health care system perspective. Cost estimates for this analysis were taken from publicly available databases and published literature. Of 268 treated patients as of April 2019, 127 (47.4%) experienced all-grade CRS and/or NEs, which were predominantly grade ≤2 (77.2%). Median total AE management costs ranged from $1930 (grade 1 NE) to $177 343 (concurrent grade ≥3 CRS and NE). Key drivers of cost were facility expenses, including intensive care unit and other inpatient hospitalization lengths of stay. HCRU and costs were significantly greater among patients with grade ≥3 AEs (22.8%). Therefore, CAR T-cell therapies with a low incidence of severe CRS/NEs will likely reduce HCRU and costs associated with managing patients receiving CAR T-cell therapy. This clinical trial was registered at www.clinicaltrials.gov as #NCT02631044.

Platelet Transfusions

Background: Chimeric antigen receptor T cell (CAR-T) therapy is successful in improving treatment outcomes for relapsed/refractory acute lymphoblastic leukemia (R/R ALL). However, toxicities associated with CAR-T therapy are being increasingly identified. Pancytopenia is one of the most common complications after CAR-T therapy, and platelet transfusions are an essential part of its supportive care.Study Design and Methods: This study aimed to assess the effectiveness of platelet transfusions for R/R ALL patients at our single center and identify associated risk factors. Overall, 44 R/R ALL patients were enrolled in this study, of whom 26 received CAR-T therapy and 18 received salvage chemotherapy.Result: Patients in the CAR-T group had a higher incidence of platelet transfusion refractoriness (PTR) (15/26, 57.7%) than those in the chemotherapy group (3/18, 16.7%) (p = 0.007). For patients receiving CAR-T therapy, multivariate analysis showed that the grade of cytokine release syndrome (CRS) was the only independent risk factor associated with PTR (p = 0.007). Moreover, higher peak serum IL-6 and IFN-γ levels suggested a higher risk of PTR (p = 0.024 and 0.009, respectively). Patients with PTR received more platelet infusion doses than those without PTR (p = 0.0426). Patients with PTR had more grade 3–4 bleeding events than those without PTR (21.4 vs. 0%, p = 0.230), and the cumulative incidence of grade 3–4 bleeding event was different (p = 0.023).Conclusion: We found for the first time that PTR is associated with the CRS grade. Improved knowledge on the mechanisms of PTR after CAR-T therapy is needed to design a rational therapeutic strategy that aims to improve the efficiency of transfusions.

Gardner et al report that early intervention with tocilizumab and steroids at the first signs of mild cytokine release syndrome (CRS) following CD19 chimeric antigen receptor (CAR) T-cell infusion for B-cell acute lymphocytic leukemia reduces the development of life-threatening severe CRS without having a negative impact on antileukemic effect.
