TRANSCEND	Individual patient data
JULIET	Schuster et al. [8] was supplemented with the EMA Public Assessment Report [33], the EMA Summary of Product Characteristics [34], the United States FDA Summary Basis for Regulatory Action [35], and Schuster et al. [16]^d

CR complete response, CRS cytokine release syndrome, DLBCL diffuse large B-cell lymphoma, EOS end of study, EMA European Medicines Agency, FDA Food and Drug Administration, liso-cel lisocabtagene maraleucel, ORR objective response rate, OS overall survival, PFS progression-free survival
^aData cutoffs with most complete data availability were included
^bMedian on-study follow-up time was reported, which was defined as (EOS date—first dose date + 1)/30.4375. If patients were continuing on study, the data cutoff date was used to impute the EOS date for the purpose of the calculation
^cMedian follow-up time from infusion to data cutoff was reported [8]
^dIn JULIET, CRS was rated according to the University of Pennsylvania criteria. However, the JULIET investigators regraded CRS events according to the Lee 2014 criteria [36]; rates of CRS associated with tisagenlecleucel were extracted from Schuster et al. [16], which was based on the Lee 2014 criteria [36] and also used in TRANSCEND
