ListOutcomeTime frameDescription
PrimaryPercentage of Participants With Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1Baseline up to disease progression or study treatment discontinuation (up to 38 months)
ORR was defined as the percentage of participants with observed tumor response of complete response (CR), or partial response (PR) determined according to RECIST version 1.1. CR was defined as the disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to \<10 millimeters (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. The percentages of participants are rounded off to the nearest single decimal point.
SecondaryPercentage of Participants With Disease Control Rate (DCR) Determined According to RECIST Version 1.1Baseline up to disease progression or study treatment discontinuation (up to 38 months)
DCR was defined as the percentage of participants with observed tumor response of CR, PR or stable disease (SD) determined according to RECIST version 1.1. CR was defined as the disappearance of all target lesions with reduction in target/non-target pathological lymph nodes to \<10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD is at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study including baseline (nadir). The percentages of participants are rounded off to the nearest single decimal point.
SecondaryDuration of Response (DoR) According to RECIST Version 1.1
From first occurrence of documented CR or PR up to disease progression or study treatment discontinuation (assessed every 8 weeks after study treatment start for the first year, and every 12 weeks thereafter, up to 38 months)
DoR was determined for participants who had a best overall response of CR or PR. CR was defined as the disappearance of all target lesions with a reduction in target/non-target pathological lymph nodes to \< 10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. DoR was defined as the time from first occurrence of a documented objective response until the time of documented disease progression or death from any cause during treatment, whichever occurs first. Participants that did not have documented progressive disease or death during the study were censored at the day of the last tumor assessment.
SecondaryProgression-Free Survival (PFS) According to RECIST Version 1.1Study treatment initiation up to disease progression or study treatment discontinuation (up to 38 months)
PFS was defined as the time from study treatment initiation (Cycle 1 Day 1 \[1 cycle=14 days for QW/Q2W cohorts; 1 cycle=21 days for Q3W cohorts\]) to the first occurrence of documented disease progression (based on Investigator's assessment) or death from any cause during treatment, whichever occurs first. Participants that did not have documented progressive disease or death during the study were censored at the day of the last tumor assessment.
SecondaryOverall Survival (OS)From first dose of study treatment up to death due to any cause (up to approximately 47 months)
OS was defined as the time from the first dose of study treatment to the time of death from any cause on study. Participants who were still alive at the time of analysis were censored at the last date known alive.
SecondaryPercentage of Participants With Adverse Events (AEs)Baseline up to end of the study (up to approximately 47 months)
An AE is any untoward medical occurrence in a participant or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
SecondaryPercentage of Participants by Programmed Death-Ligand 1 (PD-L1) Status According to Immunohistochemical MethodsBaseline
SecondaryChange From Baseline in Density of Cluster of Differentiation (CD) 8 Positive (CD8+) Cells According to Immunohistochemical MethodsBaseline up 2 months
SecondaryChange From Baseline in Density of Cluster of Differentiation 3 Negative (CD3-) Perforin Positive Cells According to Immunohistochemical MethodsBaseline up to 2 months
SecondaryChange From Baseline in Density of PD-L1 According to Immunohistochemical MethodsBaseline up to 2 months

Data was not collected for this outcome measure due to premature termination of the study by the sponsor.

Response evaluable population included all participants in the safety population who received at least one dose of simlukafusp alfa/atezolizumab and who had at least one baseline and one on-study tumor assessment. Due to early termination of the study, matured median for OS could not be achieved, hence as planned and pre-specified in the protocol, the data for OS was not analyzed and not reported.
