Clinical Trial Summary

This is a multicenter, randomized, placebo-controlled, triple blind, phase II study to determine the efficacy and safety of xevinapant with radiotherapy in older patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) of oral cavity, oropharynx, hypopharynx, or larynx. Upon confirmation of eligibility, subjects will be enrolled and randomized in a 1:1 ratio to: - Arm A: 3 cycles of xevinapant (200 mg/day from Day 1 to 14, per cycle) + intensive modulated radiotherapy (IMRT) followed by 3 cycles of xevinapant in monotherapy phase (200 mg/day from Day 1 to 14, per cycle) - Arm B: 3 cycles of placebo (from Day 1 to 14, per cycle) + IMRT followed by 3 cycles of placebo in monotherapy phase (from Day 1 to 14, per cycle). Patients will be stratified by institution, disease location/p16 status (p16 positive oropharyngeal cancer, versus others), G8 score. Three strata for the G8 will be used (>14, versus 11-14 versus <11). Patients will undergo imaging in week 20 and upon clinical suspicion of progression/recurrence. Clinical examination will take place every 12 weeks in the first 3 years.
