Study Endpoints

Primary Endpoints

Progression-free Survival at 2 Years (PFS2)
2 years

PFS2 is the percent probability estimate at 2 years based on the Kaplan-Meier method. PFS is defined as the time from the date of randomization to first invasive local, regional, distant progression, invasive second head and neck primary, or death due to any cause. Participants alive without progression are censored at date of last disease evaluation. Progression should be confirmed by biopsy or lymph node removal when feasible, but may also be determined based on clinical or pathologic evidence at the discretion of the treating investigator.

Grade 3 or 4 Adverse Event (AE) Rate
Treatment duration is up to 54 weeks, and adverse events will be collected through 30 days following the end of treatment.

Grade 3 or 4 AE rate is defined as the proportion of participants who experience grade 3 or 4 adverse events during study treatment. AEs are summarized and graded based on CTCAE 5.0.

Secondary Endpoints

Median Progression-free Survival (PFS)
Tumor assessments will be performed every 12 weeks (±2 weeks) for up to 2 years following randomization.
Median Overall Survival (OS)
Survival will be monitored every 12 weeks (±2 weeks) for up to 2 years following randomization.
Median Distant Metastatic-free Survival (DMFS)
Tumor assessments will be performed every 12 weeks (±2 weeks) for up to 2 years following randomization.
