- Primary Outcome Measures
Name Time Method Main Objective: To demonstrate improvement in PFS evaluated by an independent review committee (IRC) with xevinapant-cetuximab-RT compared to placebo-cetuximab-RT;Secondary Objective: To demonstrate improvement in OS with xevinapant-cetuximab-RT compared to placebo-cetuximab-RT (main secondary objective), To demonstrate improvement in PFS as evaluated by local investigator with xevinapant-cetuximab-RT compared to placebo-cetuximab-RT, To evaluate the treatment compliance of xevinapant-cetuximab-RT compared to placebo-cetuximab-RT, To evaluate the safety and tolerability of xevinapant-cetuximab-RT compared to placebo-cetuximab-RT;Primary end point(s): PFS as assessed by independent review committee (IRC) defined as the time from randomization to the first occurrence of any of the following events: death from any cause, disease progression (PD), primary treatment failure before achieving a complete response (CR) or any radiological or clinical relapse after achieving a CR
- Secondary Outcome Measures
Name Time Method Secondary end point(s):OS, main secondary endpoint, defined as the time from date of randomization to the date of death. Patients last known to be alive will be censored at date of last contact.;Secondary end point(s):Progression-free survival by investigator assessment.;Secondary end point(s):Compliance will be reported: for radiotherapy (tumor dose, number of fractions, duration and major deviations), for xevinapant/placebo, cetuximab (number of cycles, dose, duration, dose intensity and relative dose intensity). Whatever the treatment, treatment interruption, reduction and discontinuation and their reasons will be reported;Secondary end point(s):Occurrence of adverse events (AEs) and treatment-related AEs.
