ListOutcomeTime frameDescription
PrimaryProgression-Free Survival (PFS) Based on IRR by Treatment ArmRandomization to objective progression, death or last tumor assessment without progression before any additional anti-cancer therapy (whichever occurred first, assessed up to 33 months)
PFS was defined as the time from the date of randomization to the date of the first documentation of objective tumor progression (by IRR) or death on study due to any cause, whichever occured first. If tumor progression data included more than 1 date, the first date was used. PFS (in months) was calculated as (first event date - randomization date +1)/30.44. Progression is defined using RECIST v1.1, as at least a 20% increase (including an absolute increase of at least 5 millimeters) in the sum of diameters of target lesions, taking as reference the smallest sum on study and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.
SecondaryObjective Response Rate (ORR) - Percentage of Participants With Objective Response Based on IRRRandomization to objective progression, death or last tumor assessment without progression before any additional anti-cancer therapy (assessed up to 33 months)
Percentage of participants with objective response of complete response (CR) or partial response (PR) according to RECIST version 1.1. CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis \<10 mm). No new lesions and disappearance of all non-target lesions. PR was defined as \>=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions.
SecondaryOverall Survival (OS)From randomization to death or last date known as alive for those who were lost to follow-up or withdrew consent (assessed up to 64 months).
OS was defined as the time from randomization to the date of death due to any cause. OS (in months) was calculated as (date of death - date of randomization +1)/30.44. For participants who were lost to follow-up or withdrew consent, the OS was censored on the last date that participants were known to be alive.
SecondaryPercentage of Participants With Disease Control at 12 Weeks Based on IRRFrom randomization to Week 12
Disease Control Rate (DCR) at 12 weeks is defined as the percent of participants with CR, PR or stable disease (SD) at 12 weeks according to RECIST version 1.1 as determined by the IRR. The best response of SD can be assigned if SD criteria were met at least once after randomization at a minimum interval of 6 weeks. CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis \<10 mm). No new lesions and disappearance of all non-target lesions. PR was defined as \>=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions.
SecondaryEstimate of the Percentage of Participants Surviving at 1 Year and at 18 MonthsFrom randomization to 1 year and from randomization to 18 months
Probability of survival 1 year and 18 month after randomization. The probability of survival at 1 year was estimated using the Kaplan Meier method and a 2-sided 95% CI for the log \[-log(1-year survival probability)\] was calculated using a normal approximation and then back transformed to give a CI for the 1-year survival probability itself. The probability of survival at 18 months was estimated similarly.
SecondaryDuration of Response (DR) Based on IRRFrom objective response to date of progression, death or last tumor assessment without progression before any additional anti-cancer therapy (whichever occurred first, up to 33 months)
DR was defined as the time from the first documentation of objective tumor response (CR or PR), as determined by the IRR, to the first documentation of objective tumor progression or to death due to any cause, whichever occurred first. If tumor progression data included more than 1 date, the first date was used. DR (in weeks) was calculated as (first date of PD or death - first date of CR or PR +1)/7. DR was only calculated for the subgroup of participants with an objective tumor response.
SecondaryTime to Tumor Response (TTR) Based on IRRRandomization to first documentation of objective tumor response (up to 33 months).
TTR was defined as the time from randomization to first documentation of objective tumor response (CR or PR) as determined by the IRR. For participants proceeding from PR to CR, the onset of PR was taken as the onset of response. TTR was calculated for the subgroup of participants with objective tumor response.
SecondaryTime to Progression (TTP) Based on IRRRandomization to objective progression, death or last tumor assessment without progression before any additional anti-cancer therapy (whichever occurred first, up to 33 months)
TTP was defined as the time from the date of randomization to the date of the first documentation of objective tumor progression, as determined by IRR. If tumor progression data included more than 1 date, the first date was used. TTP (in months) was calculated as (first event date - randomization date +1)/30.44.
SecondaryIntracranial Time to Progression (IC-TTP) Based on IRRRandomization to objective intracranial progression or last tumor assessment without progression before any additional anti-cancer therapy (whichever occurred first, up to 33 months)
IC-TTP was defined similarly to TTP, but only considering intracranial disease (excluding extracranial disease) and the progression was determined based on either new brain metastases or progression of existing brain metastases.
SecondaryExtracranial Time to Progression (EC-TTP) Based on IRRRandomization to objective extracranial progression or last tumor assessment without progression before any additional anti-cancer therapy (whichever occurred first, up to 33 months)
EC-TTP was defined similarly to TTP, but only considering extracranial disease (excluding intracranial disease) and the progression was determined based on either new extracranial lesions or progression of existing extracranial lesions.
