Trial Outcomes & Findings for Efficacy and Safety Evaluation of IBI308 in Patients With Extranodal NK/T Cell Lymphoma Patients (NCT NCT03228836)

NCT ID: NCT03228836

Last Updated: 2021-01-12

Results Overview

The tumor assessment is according to Lugano 2014 Criteria and then International Working Group (IWG) 2007 Criteria after 24 weeks. Objective response is defined as best overall response (CR or PR) across all assessment time points during the period from enrollment to termination of trial treatment (per Lugano 2014 criteria during intial 24 weeks, per IWG 2007 criteria after 24 weeks). The primary efficacy endpoint is ORR evaluated using the 2014 Lugano Criteria before first progression disease (PD).

SECONDARY outcome

Timeframe: Up to ~30 months (through database cut-off date of 28-February-2020)

PFS was defined as the time from the first dose to the first documented progressive disease (PD) per Lugano 2014 or death due to any cause, whichever occurred first. Participates who neither progress nor die were censored at the date of their last tumor imaging evaluation. Participates who did not have any tumor imaging evaluation after baseline were censored on the date of enrollment.
