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
Overall Survival（OS）
Time Frame: Every 8 weeks. Survival status should be collected for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met, whichever is later.
The primary endpoint was Overall Survival (OS), which was defined as the time from random assignment to the date of death. In the absence of confirmation of death or for patients alive at the OS cutoff date, survival time was censored at the date of last trial follow-up or the cutoff date, whichever was earlier.
Every 8 weeks. Survival status should be collected for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met, whichever is later.

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
Progression-free Survival (PFS)
Time Frame: Every 8 weeks. Tumor assessments will be performed until radiologic progression develops or the start of new anticancer treatment, for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met.
Tumor assessments were performed throughout the study period and analyzed using Response Evaluation Criteria in Solid Tumors criteria (Version 1.1, 2009). Progression-free survival was defined as the time (in months) from the date of randomization until the date of the Investigator-assessed radiological disease progression or death due to any cause. Patients who received non-study cancer treatment before radiologic evidence of disease progression were censored at the date of the last evaluable tumor assessment before initiation of non-study cancer treatment.
Every 8 weeks. Tumor assessments will be performed until radiologic progression develops or the start of new anticancer treatment, for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met.
Time to Treatment Failure (TTF)
Time Frame: From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
Time to treatment failure was defined as the time (in months) from the date of randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause. Censoring for TTF was also applied for those patients who were given non-study cancer treatment, with censoring at the time when the patient began the non-study cancer treatment.
From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
Overall Response Rate (ORR; Complete Response [CR] or Partial Response [PR] Using RECIST Criteria)
Time Frame: From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
The assessment of ORR was based on Investigator review of the images according to RECIST Version 1.1. Overall response rate was defined as the proportion of patients with objective evidence of complete response (CR) or partial response (PR). At the analysis stage, the best overall response was assigned for each patient as the best response recorded from all responses recorded after study randomization. If applicable, responses recorded after disease progression or initiation of non-study cancer treatment was excluded. A patient's best response assignment of stable disease (SD) needed to be maintained for at least 6 weeks after study randomization. If a patient didn't meet this condition, best response was assigned "Not evaluable".
From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
Disease Control Rate (DCR; CR, PR, or Stable Disease)
Time Frame: From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
The assessment of DCR paralleled that of ORR, with DCR defined as the proportion of patients with objective evidence of CR, PR, or SD.
From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
Duration of Response
Time Frame: From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
Duration of response was derived for those patients with objective evidence of PR or CR. Duration of response was defined as the time from the first documentation of response (CR or PR) to the first documentation of objective tumor progression or to death due to any cause. Patients alive and progression free as of the analysis cut-off date were censored at their last evaluable tumor response assessment prior to initiation of any non-study cancer treatment.
From randomization until the date of radiologic disease progression, permanent discontinuation of study treatment, or death due to any cause, assessed up to 30 months.
Safety and Tolerability Evaluation Will Focus on Adverse Events and Laboratory Assessments（Adverse Events）
Time Frame: From the time a patient signed informed until 30 day safety follow-up visit or until initiation of new anticancer treatment, or assessed up to 30 months.
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Treatment-related AEs were events between administration of study drug and up to 30 Days that were absent before treatment or that worsened relative to pre-treatment state. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability /incapacity; congenital anomaly. The AEs were graded for severity using National Cancer Institute Common Terminology Criteria for AEs.
From the time a patient signed informed until 30 day safety follow-up visit or until initiation of new anticancer treatment, or assessed up to 30 months.
Safety and Tolerability Evaluation Will Focus on Adverse Events and Laboratory Assessments（Laboratory Assessments）
Time Frame: From the time a patient signed informed until 30 day safety follow-up visit or until initiation of new anticancer treatment, or assessed up to 30 months.
All laboratory values that were out of the normal range were to be evaluated for their clinical significance before exposing the patient to the next dose of study medication. Any laboratory abnormality that was clinically significant, e.g., results in delay of study medication dosing, study discontinuation, required treatment due to abnormal values, or was considered by the Investigator to be medical important, were to be reported as an AE, unless it was considered part of clinical manifestations to a clinical diagnosis that has already been reported as an AE.
From the time a patient signed informed until 30 day safety follow-up visit or until initiation of new anticancer treatment, or assessed up to 30 months.
Overall Survival（OS）(Wild Type KRAS)
Time Frame: Every 8 weeks. Survival status should be collected for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met, whichever is later.

The primary end point was OS, which was defined as the time from random assignment to the date of death. In the absence of confirmation of death or for patients alive at the OS cutoff date, survival time was censored at the date of last trial follow-up or the cutoff date, whichever was earlier.

The OS indicated above as secondary outcome was analyzed by wild type KRAS.
Every 8 weeks. Survival status should be collected for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met, whichever is later.
Overall Survival（OS）(Mutant Type KRAS)
Time Frame: Every 8 weeks. Survival status should be collected for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met, whichever is later.

The primary end point was OS, which was defined as the time from random assignment to the date of death. In the absence of confirmation of death or for patients alive at the OS cutoff date, survival time was censored at the date of last trial follow-up or the cutoff date, whichever was earlier.

The OS indicated above as secondary outcome was analyzed by mutant type KRAS.
Every 8 weeks. Survival status should be collected for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met, whichever is later.
Progression-free Survival (PFS) (Wild Type KRAS)
Time Frame: Every 8 weeks. Tumor assessments will be performed until radiologic progression develops or the start of new anticancer treatment, for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met.
Progression-free survival was defined as the time (in months) from the date of randomization until the date of the Investigator-assessed radiological disease progression or death due to any cause. Patients who received non-study cancer treatment before radiologic evidence of disease progression were censored at the date of the last evaluable tumor assessment before initiation of non-study cancer treatment. The PFS indicated above as secondary outcome was analyzed by wild type KRAS.
Every 8 weeks. Tumor assessments will be performed until radiologic progression develops or the start of new anticancer treatment, for up to 12 months after the last patient is randomized or until the target number of events (deaths) is met.
