Primary Outcome Measures :
  1. Disease-free survival (DFS) [ Time Frame: Through study completion, up to 5 years ]

    DFS defined as the time from randomization to occurrence of any of the following events, whichever occurs first:

    • Locoregional recurrence or distant metastases as determined by an independent central radiology assessment.
    • Occurrence of second primary (same or other) cancer as determined by an independent central radiology assessment.
    • Death from any cause.
    • Loss to follow-up is censored.


Secondary Outcome Measures :
  1. Relapse-free survival (RFS) [ Time Frame: Through study completion, up to 5 years ]

    RFS is defined as the time from randomization to occurrence of any of the following events, whichever occurs first:

    • Locoregional recurrence or distant metastases as determined by the investigator.
    • Death from any cause.
    • Occurrence of second primary (same or other) cancer as determined by the investigator is ignored.
    • Loss to follow-up is censored.

  2. Time to recurrence (TTR) [ Time Frame: Through study completion, up to 5 years ]

    TTR is defined as the time from randomization to occurrence of any of the following events (i.e., events related to the same cancer), whichever occurs first:

    • Locoregional recurrence or distant metastases as determined by the investigator.
    • Death from same cancer.
    • Occurrence of second primary (same or other) cancer as determined by the investigator is ignored.
    • Loss to follow-up and deaths from other cancer, non-cancer-related deaths, treatment-related deaths are censored.

  3. Time to treatment failure (TTF) [ Time Frame: Through study completion, up to 5 years ]

    TTF is defined as the time from randomization to occurrence of any of the following events, whichever occurs first:

    • Locoregional recurrence or distant metastases as determined by the investigator.
    • Occurrence of second primary (same or other) cancer as determined by the investigator.
    • Death from any cause except non-cancer related death.
    • Loss to follow-up and non-cancer-related deaths are censored.

  4. Overall survival (OS) [ Time Frame: Through study completion, up to 5 years ]
    OS defined as the time from randomization to death from any cause.

  5. Change of Circulating tumor DNA (ctDNA) status (every 3 months) [ Time Frame: Through study completion, up to 5 years ]
  6. Occurrence of treatment emergent adverse event (TEAE) [ Time Frame: 15 months ]
    TEAE, including Grade 3+, serious, fatal TEAE by relationship (AEs graded according to the National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events, version 5.0 [CTCAE v5.0])

  7. Occurrence of dose reduction and discontinuation of IMP due to a TEAE. [ Time Frame: 15 months ]
