Inclusion Criteria

• Participants with Eastern Cooperative Oncology Group Performance Status (ECOG
PS) 0-2 and able to tolerate standard of care IMRT treatment according to
Investigator assessment.
• Participants with histologically confirmed squamous cell carcinoma with one
of the following primary sites: oral cavity, oropharynx, hypopharynx or larynx.
Participants have received surgery with curative intent on these sites in the
past 4 to 8 weeks before start of treatment (Cycle 1 Day 1)
• Oropharynx (OPC) participants must have known human papillomavirus (HPV)
status as determined by p16 expression using immunohistochemistry ICH)
• Participants with no residual disease by computed tomography (CT) or magnetic
resonance imaging (MRI) and have a high risk of relapse with 1 or 2 of the
following criteria, confirmed by local histopathology:
• nodal extra-capsular extension (ECE) and positive resection margins (R1 or
close margin less than or equal to (<=) 1 millimeter (mm)
• Are unfit to receive high-dose cisplatin by meeting one or more of the
following criteria: estimated glomerular filtration rate (eGFR) < 60
milliliter per minute per 1.73 meter square (mL/min /1.73 m^2); History of
hearing impairment, defined as Grade >= 2 audiometric hearing loss or tinnitus
Grade >=2. An audiogram is not required if one of the other criteria meets
unfitness to receive high-dose cisplatin; Peripheral neuropathy > = Grade 2 and
if >= 70 years, unfit according to G8 questionnaire (Score <= 14) or ineligible
for cisplatin treatment due to age limit to national guidelines
• Participants with adequate hematologic, renal and hepatic function as defined
in the protocol
• Other protocol-defined inclusion criteria could apply

Exclusion Criteria

in the Investigator*s opinion constitutes an inappropriate risk or a
contraindication for participation in the study or that could interfere with
the study objectives, conduct, or evaluation
• Participant with incomplete surgery
• Primary tumor of nasopharyngeal, paranasal sinuses, nasal cavity, salivary,
thyroid or parathyroid gland, skin or unknown primary site
• Prior definitive, neoadjuvant, concurrent or adjuvant (C)RT to the head and
neck region which may jeopardize the primary tumor irradiation plan,or any
other prior SCCHN systemic treatment, including investigational agents
• Participation in any interventional clinical study within 28 days prior to
screening or during participation in this study
• Known contraindication to undergoing positron emission tomography with
18F-FDG-PET-CT scans, or both contrast-enhanced MRI and contrast enhanced CT
scans
• Known allergy to Xevinapant (Debio 1143) or any excipient known to be present
in Xevinapant (Debio 1143) or in the placebo formulation
