About

This is a non-interventional, retrospective cohort study using the Flatiron Health Research Database (FHRD) and data from the single-arm phase II JULIET clinical trial (NCT02445248).

Full description

JULIET is a single-arm, open-label, multi-center phase II study of tisagenlecleucel involving adult patients with r/r DLBCL who were ineligible for or had disease progression after autologous hematopoietic stem-cell transplantation.

Patients enrolled in JULIET will be referred to as the trial cohort in this study. Outcomes observed in the trial cohort will be compared against a cohort of patients receiving standard of care, defined as the real-world cohort in this study. The real-world cohort will be derived from the FHRD by applying relevant JULIET trial inclusion and exclusion criteria that are feasible to apply in the FHRD.
