1: no definition of CRS supplied, but patients showed signs of CRS. 2: death due to cerebral hemorrhage in the context of coagulopathy and resolving cytokine release syndrome. 3: 1 death due to °V CRS before dose adjustment to disease burden. 4: 2 deaths attributed to CRS, 1 to pulmonary embolism. 5: 1 death due to neurotoxicity. 6:1 death to °V CRS with °V cerebral edema refractory to tocilizumab, siltuximab, dexamethasone before reduction of CAR T cell dose. 7: not further specified. 8: 6 fatal AEs attributed to blinatumomab, one due to °IV CRS with °V respiratory failure. 9: 1 death due to fungal infection of the brain after HSCT classified as possibly related to blinatumomab. 10: 3 deaths due to sepsis and candida infection classified as possibly related to blinatumomab. 11: CRP > 20 mg/dl: positive predictive value only 50%.12: 2 patients received steroids additional to tocilizumab for not reported reasons.13: 2 of 9 patients treated with immunosuppression (not further specified if related to tocilizumab or glucocorticoids) relapsed. 14: 48 patients evaluable. *: statistically significant
