Outcome Measures
Primary Outcome Measures
- Dose-limiting toxicity (DLT) [After1 cycle of treatment of the safety run-in phase patients (each cycle is 28 days)]
- Overall response rate (ORR) [Up to approximately 2 years]
- Incidence and severity of adverse events (AE) and serious adverse events (SAE) [Up to approximately 2 years]
Incidence, nature, and severity of adverse events graded according to the NCI CTCAE v5.0.
Secondary Outcome Measures
- Progression-free Survival (PFS) [Up to approximately 2 years]
PFS, defined as the time from randomization to the first occurrence of disease progression as determined by the investigator with use of RECIST v1.1 or death from any cause, whichever occurs first.
- Disease Control Rate (DCR) [Up to approximately 2 years]
Determined using RECIST v1.1 criteria.
- Overall Survival (OS) [Up to approximately 2 years]
Duration from the date of initial treatment to the date of death due to any cause.
