Trial Outcomes & Findings for Targeting PD-1 Therapy Resistance With Focused High or High and Low Dose Radiation in SCCHN (NCT NCT03085719)

NCT ID: NCT03085719

Last Updated: 2025-02-25

Results Overview

The primary endpoint of this study is progression-free survival (PFS) rate at 3 months. Patients are considered progression-free at 3 months if progression is not observed at the 3-month disease assessment. PFS is defined as the time from registration to disease progression per RECIST or death, whichever occurred first. Progressive Disease is defined as at least a 20% increase in the sum of diameters of target lesions, which must also demonstrate an absolute increase of at least 5 mm (with reference to the smallest sum on study). The appearance of one or more new lesions is also considered progressions (RECIST guidelines version 1.1).

PRIMARY outcome

Timeframe: 1 year

Population: The groups of 'High Dose Radiation + Pembrolizumab' and 'High Dose + Low Dose Radiation + Pembrolizumab' listed under Primary Outcome were the predefined groups in the study protocol; this was not a dose escalation study for pembrolizumab.

The primary endpoint of this study is progression-free survival (PFS) rate at 3 months. Patients are considered progression-free at 3 months if progression is not observed at the 3-month disease assessment. PFS is defined as the time from registration to disease progression per RECIST or death, whichever occurred first. Progressive Disease is defined as at least a 20% increase in the sum of diameters of target lesions, which must also demonstrate an absolute increase of at least 5 mm (with reference to the smallest sum on study). The appearance of one or more new lesions is also considered progressions (RECIST guidelines version 1.1).
