  • Safety and Tolerability as assessed by incidence and severity of Adverse Events (AEs), Serious Adverse Events (SAEs), AEs of Special Interest (AESIs), Changes in Laboratory Values, Vital Signs, Electrocardiogram (ECGs) and Extent of Exposure [ Time Frame: From signed informed consent to EOS (within 6.8 years) ]

  • Number of Participants with Clinically Significant Electrocardiograms Assessed by NCI-CTCAE v 5.0 [ Time Frame: From signed informed consent to EOS (within 6.8 years) ]
  • Extent of exposure [ Time Frame: From first study treatment dose to End of Treatment (EOT); (Up to 15 days after Cycle 6 (each cycle is of 15 days) ]
  • Changes from baseline in Quality of Life and Fatigue using European Organisation for Research and Treatment of Cancer Quality of life Questionnaire (EORTC QLQ-C30) Score [ Time Frame: From randomization to EOS (within 60 months post randomization) ]
    The EORTC QLQ-C30 version 3.0 questionnaire captures Health-Related Quality of Life (HRQL) dimensions that are common to cancer participants independently of the cancer type by which they are affected. The total scores are transformed from 0 to 100, where higher score indicates better outcome.
  • Changes from baseline in Swallowing and Pain using EORTC QLQ Head and Neck Cancer Module (EORTC QLQ-HN35) Score [ Time Frame: From randomization to EOS (within 60 months post randomization) ]
    The EORTC QLQ-HN35 is a disease-specific module capturing HRQL dimensions that affect head and neck cancer patients. The total scores are transformed from 0 to 100, where higher score indicates more severe symptoms.
