Primary Outcome Measures
NameTimeMethod
Objective response rate (ORR) using iRECIST 1.1 criteriaFrom time of first dose of study treatment until disease progression or death (up to 2 years)

ORR is defined as the proportion of patients who achieved a best response of complete response (CR) or partial response (PR) using iRECIST 1.1 criteria, and will be evaluated for both the lesion(s) treated with RT, referred to as "Target lesion (RT+ Tisle), as well as the lesion(s) not treated with RT (if applicable), referred to as "Target lesion (Tisle only)", per the prescribed treatment.

Adverse Events (AEs)From time of first dose of study treatment until the end of follow-up (up to 2 years)

Number of participants experiencing any sign, symptom, disease, or worsening of preexisting condition temporally associated with study therapy and irrespective of causality to study therapy.

Secondary Outcome Measures
NameTimeMethod
Duration of Response (DOR)From time of first dose of study treatment until disease progression or death (up to 2 years)

The time between the date of first confirmed response to the date of the first documented tumor progression, or death due to any cause, whichever occurs first.

Progression Free Survival (PFS)From time of first dose of study treatment until disease progression or death (up to 2 years)

PFS is the average length of time after the start of treatment in which a person is alive, and their cancer does not grow or spread. PFS is defined as the time from day 1 of treatment until the criteria for disease progression is met as defined by RECIST1.1 or death as a result of any cause.

Change From Baseline Quality of Life (GHS/QoL)From time of first dose of study treatment until disease progression or death (up to 2 years)

Change from baseline in QoL using the European Organization for Research and Treatment of Cancer Head and Neck Questionnaire (EORTC QLQ-H\&N35)
