Outcome Measures
Primary Outcome Measures
- Overall response rate （ORR） [2 years]
Defined as percentage of participants achieving complete response (CR) and partial response (PR) assessed by the investigator according to the RECIST 1.1
Secondary Outcome Measures
- Overall survival (OS) [3 years]
OS is defined as the time from registration to death due to any cause.
- Progression-Free Survival (PFS) [3 years]
PFS is defined as the time from registration to the first documented disease progression or death due to any cause, whichever occurs first.
- Duration of Response (DOR) [3 years]
For participants who demonstrate CR (disappearance of all target lesions) or PR (≥30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters), DOR is defined as the time from first documented evidence of CR or PR until disease progression per RECIST 1.1 based on assessments by the investigator or death due to any cause, whichever occurs first.
- Disease Control Rate (DCR) [2 years]
DCR is defined as the percentage of participants in the analysis population who have a CR, PR or stable disease per RECIST 1.1
- Adverse event (AE) [2 years]
An AE is any untoward medical occurrence in a participant that is temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study treatment. The number of participants who experience an AE will be reported
