Primary | Overall Response Rate (ORR) | Complete Response (CR) and Partial Response (PR) according to the Lugano classification as determined by the Investigator. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Duration of Response (DOR) | Time from CR or PR, whichever occurs first, to relapse or death due to DLBCL. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Time to response (TTR) | Time from tisagenlecleucel infusion to CR or PR, whichever occurs first. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Progression-Free Survival (PFS) | Time from tisagenlecleucel infusion to the first documented disease progression or death due to any cause. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Event free survival (EFS) | Time from tisagenlecleucel infusion to the first documented disease progression or relapse, new treatment for lymphoma or death due to any cause. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Overall Survival (OS) | Time from tisagenlecleucel infusion to death due to any cause. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Number of Participants with On-Treatments Adverse Events, Serious Adverse Events, and Deaths | Analysis of absolute and relative frequencies for treatment emergent AE, SAE and Deaths by primary System Organ Class (SOC) through the monitoring of relevant clinical and laboratory safety parameters. | From first dosing (single administration, Day 1) up to End of Study Visit (EOS), an average of 60 Months | |
Secondary | Tisagenlecleucel immunogenicity (humoral) | The humoral immunogenicity assay will be evaluated to measure the antibody titers specific to the tisagenlecleucel molecule prior to and following infusion. | Up to Month 60 | |
Secondary | Tisagenlecleucel immunogenicity (cellular) | The cellular immunogenicity assay will be evaluated to assess the presence of T lymphocytes activated by the tisagenlecleucel protein. | Up to Month 60 | |
Secondary | In vivo cellular PK profile of tisagenelecleucel | qPCR and flow cytometry to measure tisagenlecleucel transgene concentration in blood, bone marrow and other matrices/tissues. | Up to Month 60 | |
Secondary | Concentration of Tocilizumab PK in tocilizumab treated subjects during CRS | Concentration of Tocilizumab | Up to Day 7 after tocilizumab infusion | |
Secondary | Serum cytokines (IL-10, interferon gamma, IL-6, CRP and ferritin) | Concentration of soluble factors (IL-10, interferon gamma, IL-6, CRP and ferritin) will be listed and summarized by participant and time point. | Up to Month 60 |
