Primary Outcome Measures :
  1. Dose-limiting Toxicity (DLT) [ Time Frame: 8 weeks ]
    The primary outcome for this study is dose-limiting toxicities (DLTs) during the first 2 cycles of therapy, expressed as the number of DLT events per treatment/dose group. All grades per the Common Terminology Criteria for Adverse Events (CTCAE). DLT is defined as a related and clinically significant adverse event (AE), including missed doses due to a related AE. Due to limited number of characters that can present in this field, it is not possible to consistently provide additional details across all sub elements of this outcome. See protocol. The outcome is expressed as the number of DLT events by treatment and dose level, a number without dispersion.


Secondary Outcome Measures :
  1. Treatment emergent Adverse Events (TEAE) [ Time Frame: 2 years ]
    Treatment emergent adverse events (TEAEs) are defined as adverse events of any grade with initial onset or increasing in severity after the first dose of study treatment until 30 days after last dose of study drug. Pregnancy during the reporting period will be classified as a serious adverse event. The outcome will be expressed as the number of events by treatment and dose level, stratified by relatedness and Common Terminology Criteria for Adverse Events (CTCAE) grade. The result is a number without dispersion.

  2. Objective Tumor Response Rate [ Time Frame: 18 months ]

    Objective tumor response will be assessed as achieving a Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 Complete Response (CR) or a Partial Response (PR). The outcome will be reported as the number of subjects that achieve an overall response (OR) to treatment, ie, CR or PR, within 18 months of starting treatment. The outcome will be reported by treatment and dose level as a number without dispersion. RECIST criteria are:

    • CR = Disappearance of all target lesions
    • PR = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • Overall Response (OR) = CR + PR
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
    • Stable disease (SD) = Small changes that do not meet any of the above criteria

  3. Progression-free Survival (PFS) [ Time Frame: 2 years ]

    Progression free survival (PFS) means the participant remains alive without return or relapse of the tumor. The outcome is defined as the number of days to either progressive disease as defined per RECIST v1.1 or death, and reported as the median PFS with full range. RECIST criteria are:

    • CR = Disappearance of all target lesions
    • PR = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • Overall Response (OR) = CR + PR
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
    • Stable disease (SD) = Small changes that do not meet any of the above criteria

  4. Clinical Benefit Rate [ Time Frame: 6 months ]

    Clinical benefit is defined as achieving a Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 Complete Response (CR) ; Partial Response (PR); or Stable Disease (SD). The outcome will be reported as the number of subjects that achieve a CR; PR; or SD, within 6 months of starting treatment. The outcome will be reported by treatment and dose level as the number of participants receiving clinical benefit, a number without dispersion. RECIST criteria are:

    • CR = Disappearance of all target lesions
    • PR = ≥ 30% decrease in the sum of the longest diameter of target lesions
    • SD = Small changes that do not meet any of the above criteria
    • Progressive disease (PD) = 20% increase in the sum of the longest diameter of target lesions, and/or the appearance of one or more new lesion(s)
    • SD = Small changes that do not meet any of the above criteria
