The main purpose of this study is to assess the efficacy and safety of volrustomig compared to observation in participants with unresected locally advanced head and neck squamous cell carcinoma (LA-HNSCC) who have not progressed after receiving definitive concurrent chemoradiotherapy (cCRT).

Progression-Free Survival (PFS) in participants with unresected LA-HNSCC with PD-L1 expressing tumors
PFS is defined as time from randomization until first objective radiological progression per RECIST 1.1 as assessed by Blinded Independent Central Review (BICR), or death due to any cause (in the absence of progression). The analysis will include all randomized participants with PD-L1 expressing tumors.
Time frame: Up to approximately 8 years
Progression-Free Survival (PFS) in the unresected LA-HNSCC intent-to-treat (ITT) population
PFS is defined as time from randomization until first objective radiological progression per RECIST 1.1 as assessed by BICR, or death due to any cause (in the absence of progression). The analysis will include all randomized participants.
Time frame: Up to approximately 8 years
Landmark Progression-Free Survival (PFS) Rates
PFS is defined as time from randomization until first objective radiological progression per RECIST 1.1 as assessed by BICR, or death due to any cause (in the absence of progression). These analyses will include participants with PD-L1 expressing tumors and all randomized participants.
Time frame: Up to approximately 8 years
Overall Survival (OS) in participants with unresected LA-HNSCC with PD-L1 expressing tumors
Overall survival (OS) is defined as the time from randomization until the date of death due to any cause. The analysis will include all randomized participants with PD-L1 expressing tumors.
Time frame: Up to approximately 8 years
Landmark Overall Survival (OS) Rates
OS is defined as the time from randomization until the date of death due to any cause. These analyses will include participants with PD-L1 expressing tumors as randomized and all randomized participants.

Overall Survival (OS) in the unresected LA-HNSCC ITT population
OS is defined as the time from randomization until the date of death due to any cause. The analysis will include all randomized participants.
Time frame: Up to approximately 8 years
Progression Free Survival 2 (PFS2)
PFS2 is defined as the time from randomization until the earliest of the progression event (following the initial investigator-assessed progression), after the start of the first subsequent therapy, or death from any cause, whichever occurs first. The date of the second progression will be recorded by the investigator in the eCRF and defined according to local standard clinical practice. These analyses will include participants with PD-L1 expressing tumors as randomized and all randomized participants.
Time frame: Up to approximately 8 years
Presence of Anti-Drug-Antibodies (ADAs) against volrustomig in serum
To investigate the immunogenicity of volrustomig.
Time frame: Up to approximately 8 years
Participant-reported physical functioning
Change from baseline of physical functioning as measured by scores on the Patient-Reported Outcomes Measurement Information System (PROMIS) Short Form v.20 - Physical Function 8c are reported on a T score metric (mean = 50 and SD = 10), with higher scores reflecting better physical functioning. The analysis will include all randomized participants.
Time frame: Up to approximately 8 years
Participant-reported global health status (GHS)/quality of life (QoL)
Change from baseline of Global Health Status/Quality of Life subscale scores as measured by the European Organization for Research and Treatment of Cancer (EORTC) Item Library 172 are transformed to a 0-100 range; a higher score represents higher quality of life. The analysis will include all randomized participants.
Time frame: Up to approximately 8 years
Percentage of participants with Adverse Events
Adverse Events as assessed by Common Terminology Criteria for Adverse Events (CTCAE).
Time frame: Up to approximately 8 years
Area under the curve (AUC)
The concentration of Volrustomig in serum will be determined. Area under the curve is the integral of the concentration-time curve. The AUC reflects the actual body exposure to drug after administration. The AUC is dependent on the rate of elimination of the drug from the body and the dose administered.
Time frame: Up to approximately 8 years
Maximum plasma concentration of the drug (Cmax)
The concentration of Volrustomig in serum will be determined (Cmax will be derived).
Time frame: Up to approximately 8 years
The time taken to reach the maximum concentration (Tmax)
The concentration of Volrustomig in serum will be determined (Tmax will be derived).
Time frame: Up to approximately 8 years
