Study Summary

The purpose of this study is to evaluate the efficacy of inotuzumab ozogamicin plus rituximab in relapsed/refractory aggressive Non-Hodgkin lymphoma patients who are not candidates for intensive high-dose chemotherapy. Specifically, the goal is to demonstrate the superiority of this combination compared with an active comparator arm (investigator's choice of rituximab+bendamustine or rituximab+gemcitabine) using the primary endpoint of overall survival.

Primary Outcome

Overall Survival (OS) was defined as the time from randomization to death due to any cause, censoring at the date of last contact or the end of the study. The Kaplan-Meier method was used to determine OS. The hazard ratio and corresponding 95% 2-sided confidence interval were calculated using stratified Cox proportional hazard regression.
