Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Radiotherapy added to systemic treatment; Pembrolizumab 200 mg every 3 weeks until disease progression or unacceptable toxicity. Loco-regional radiotherapy will start at D8 after the first administration of pembrolizumab (D1) with 54 Gy/18 fractions in the head and neck region. If the investigator decides before randomization to add chemotherapy with pembrolizumab, the chemotherapy will start from cycle 3 or 4 of pembrolizumab (after radiotherapy administration) and will combine carboplatin AUC 5 mg/mL/min or cisplatin 100 mg/m² every 3 weeks with 5-FU 1000 mg/m²/day during 4 days every 3 weeks for a maximum of 6 cycles	Drug: Pembrolizumab; Pembrolizumab 200 mg every 3 weeks until disease progression (as confirmed according to response evaluation criteria in solid tumors version 1.1 (RECIST v1.1)) or unacceptable toxicity. The treatment of pembrolizumab should not be delayed because of radiotherapy planning.; Other Names: KEYTRUDA; Radiation: Loco-regional radiotherapy; The loco-regional radiotherapy will start at D8 after the first administration of pembrolizumab (D1) (if delayed, RT should be started no later than three weeks after the first administration of pembrolizumab, i.e. before the second administration of pembrolizumab if possible), with 54 Gy/18 fractions in the head and neck region. The volume of RT will include only involved loco-regional tumor region and no prophylactic neck volume will be necessary.; Drug: Chemotherapy; If the investigator decides before randomization to add chemotherapy with pembrolizumab, the chemotherapy will be composed of carboplatin AUC 5 mg/mL/min or cisplatin 100 mg/m² every 3 weeks with 5-FU 1000 mg/m²/day during 4 days every 3 weeks for a maximum of 6 cycles
Active Comparator: Systemic treatment; Pembrolizumab 200 mg every 3 weeks until disease progression or unacceptable toxicity. If the investigator decides before randomization to add chemotherapy with pembrolizumab, the chemotherapy will be composed of carboplatin AUC 5 mg/mL/min or cisplatin 100 mg/m² every 3 weeks with 5-FU 1000 mg/m²/day during 4 days every 3 weeks for a maximum of 6 cycles	Drug: Pembrolizumab; Pembrolizumab 200 mg every 3 weeks until disease progression (as confirmed according to response evaluation criteria in solid tumors version 1.1 (RECIST v1.1)) or unacceptable toxicity. The treatment of pembrolizumab should not be delayed because of radiotherapy planning.; Other Names: KEYTRUDA; Drug: Chemotherapy; If the investigator decides before randomization to add chemotherapy with pembrolizumab, the chemotherapy will be composed of carboplatin AUC 5 mg/mL/min or cisplatin 100 mg/m² every 3 weeks with 5-FU 1000 mg/m²/day during 4 days every 3 weeks for a maximum of 6 cycles

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free survival (PFS)	The progression-free survival is the length of time during and after the treatment of a disease that a patient lives with the disease but it does not get worse.	From randomization to disease progression or death, up to 3 years.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall survival (OS)	The overall survival is the length of time from randomization that patients enrolled in the study are still alive. The outcome is to evaluate whether the radiotherapy improves overall survival compared to standard of care.	From randomization to death from any cause, up to 5 years.
Quality of life questionnaire - Core 30 (QLQ-C30)	Developed by the EORTC, this self-reported questionnaire assesses the health-related quality of life of cancer patients in clinical trials. The questionnaire includes five functional scales (physical, everyday activity, cognitive, emotional, and social), three symptom scales (fatigue, pain, nausea and vomiting), a health/quality of life overall scale, and a number of additional elements assessing common symptoms (including dyspnea, loss of appetite, insomnia, constipation, and diarrhea), as well as, the perceived financial impact of the disease. All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level.	At baseline, 4 months, 6 months, 12 months, 18 months, 2 years, 3 years, and 4 years
Quality of Life Questionnaire - Head & Neck Cancer Module (QLQ-H&N35)	The head & neck cancer module is a 35-item questionnaire designed for use among a wide range of patients with head & neck cancer, varying in disease stage and treatment modality. It includes 7 multi-item scales that assess pain (4 items), swallowing (4 items), senses (2 items), speech (3 items), social eating (4 items), social contact (5 items), and sexuality (2 items). There are also 11 single items. Using a 4-point Likert scale (1 = "not at all", 2 = "a little", 3 = "quite a bit", and 4 = "very much"), patients indicate the degree to which they have experienced symptoms. For all items and scales, high scores indicate more problems.	At baseline, 4 months, 6 months, 12 months, 18 months, 2 years, 3 years, and 4 years
Objective response rate (ORR)	The Objective response rate is defined as the presence of a partial response (PR) or complete response (CR) observed at week 18. The investigator will evaluate the objective response using RECIST v1.1.	At 18 weeks and 21 weeks
Loco-regional progression	Locoregional disease progression is defined as the time from randomization to the first documented locoregional progression evaluated by RECIST v1.1.	From randomization to loco-regional progression, up to 5 years.
Distant progression	Distant progression is defined as the time from randomization to the first documented distant disease progression evaluated by RECIST v1.1.	From randomization to distant progression, up to 5 years.
Progression-free survival 2 (PFS2)	Progression-free survival 2 is defined as time from randomization to a second tumor progression (according to RECIST V1.1) on next-line treatment (given after a first progression) or death from any cause. Patients who did not have a progression after the initial treatment are counted as an event at the time of death if they died whatever the cause of death or are censored at the time of last news if they are alive. Patients who had a progression after the initial treatment are counted as an event when they progressed again under or after the treatment of the first progression (if they start a new treatment, i.e. a third treatment, they are also counted as an event) or when they died whatever the cause of death or they are censored at the time of last news if they are alive without new progression after the first progression.	Up to 5 years after randomization.
Incidence of Treatment Adverse Events	The tolerance and safety will be evaluated by toxicity (acute [<1 months after the end of pembrolizumab] and late [≥1 month after the end of pembrolizumab]), assessed using the Common terminology criteria for adverse events version 5.0 (CTCAE v5.0).	Throughout study completion, up to 5 years.
Compliance to treatment	Compliance to treatment is defined by the difference on recieved study regimen compared to the planned study regimen.	Throughout study treatment, up to 5 years
