What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Complete Response (CR) or Partial Response (PR)（Objective response rate [ORR]）
Time Frame: Up to approximately 12 months
ORR was the percentage of participants achieving a best overall response (BOR) of complete response (CR) or partial response (PR) as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. CR defined as the disappearance of all target and non-target lesions and no appearance of new lesions. PR defined as at least a 30% decrease in the sum of the longest diameters (LD) of target lesions (taking as reference the baseline sum LD), no progression of non-target lesions, and no appearance of new lesions.
Up to approximately 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival (OS)
Time Frame: From Date of the First Dose until Death Due to Any Cause (Up To 24 Months)
OS defined as the time from first dose date to the date of death due to any cause. For each participant who is not known to have died as of the data-inclusion cutoff date for overall survival analysis, OS time was censored on the last date the participant is known to be alive.
From Date of the First Dose until Death Due to Any Cause (Up To 24 Months)
Duration of Response (DOR)
Time Frame: From Date of CR, PR until Disease Progression or Death Due to Any Cause (Up To 12 Months)
DOR was the time from the date of first evidence of CR or PR to the date of objective progression or the date of death due to any cause, whichever is earlier.
From Date of CR, PR until Disease Progression or Death Due to Any Cause (Up To 12 Months)
Progression Free Survival (PFS)
Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 24 Months)
PFS defined as the time from the first day of therapy to the first evidence of disease progression as defined by RECIST v1.1 or death from any cause. Progressive Disease (PD) was at least a 20% increase in the sum of the diameters of target lesions, with reference being the smallest sum on study and an absolute increase of at least 5 mm, or unequivocal progression of non-target lesions, or 1 or more new lesions. If a participant does not have a complete baseline disease assessment, then the PFS time was censored at the date of first dose, regardless of whether or not objectively determined disease progression or death has been observed for the participant. If a participant was not known to have died or have objective progression as of the data inclusion cutoff date for the analysis, the PFS time was censored at the last adequate tumor assessment date.
From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 24 Months)
Percentage of Participants With CR, PR or SD
Time Frame: Disease Control Rate [DCR]) [ Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 12 Months)
Disease Control Rate (DCR) was the percentage of participants with a best overall response of CR, PR, or Stable Disease (SD) as per Response using RECIST v1.1 criteria. SD was neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD for target lesions, no progression of non-target lesions, and no appearance of new lesions.
Disease Control Rate [DCR]) [ Time Frame: From Date of First Dose until Disease Progression or Death Due to Any Cause (Up To 12 Months)
