This measure looks at how long participants who cannot receive cisplatin (a type of chemotherapy) live after being placed into a treatment group in the primary study.

Overall Survival (OS) is defined as the time between the date a participant is randomized (assigned to a treatment group) and the date of death from any cause. For participants without documentation of death, OS will be measured up to the last date the participant was known to be alive. If a participant was randomized but had no follow-up information, OS will be counted from the date of randomization.

This helps to understand if the treatment can help people who are unable to receive cisplatin chemotherapy live longer.

This measure looks at how long participants with PD-L1 positive tumors (meaning their tumor cells have at least 1% PD-L1, as determined by a laboratory test called immunohistochemistry or IHC) live after being placed into a treatment group in the primary study.

Overall Survival (OS) is defined as the time between the date a participant is randomized (assigned to a treatment group) and the date of death from any cause. For participants without documentation of death, OS will be measured up to the last date the participant was known to be alive. If a participant was randomized but had no follow-up information, OS will be counted from the date of randomization.

This helps to understand whether the treatment can help people with PD-L1 positive tumors live longer.

All PD-L1 >= 1% Randomized Participants - Primary Study

This measure looks at how long all participants live after being placed into a treatment group in the primary study.

Overall Survival (OS) is defined as the time between the date a participant is randomized (assigned to a treatment group) and the date of death from any cause. For participants without documentation of death, OS will be measured up to the last date the participant was known to be alive. If a participant was randomized but had no follow-up information, OS will be counted from the date of randomization.

This helps to understand whether the treatment can help all participants in the study live longer.

All Randomized Participants - Primary Study

This measure looks at how long people who cannot receive cisplatin chemotherapy live without their cancer getting worse after being assigned to a treatment group in the primary study. Progression-Free Survival (PFS) is the time from when a participant is assigned to a group (randomization) until their cancer is first shown to get worse (progress), based on reviews by independent experts who do not know which treatment was given. These experts use standard rules (RECIST 1.1) to decide if the cancer has progressed. If a participant dies before their cancer is shown to get worse, the date of death will be used as the time their disease progressed. If a participant's cancer does not get worse and they do not die during the study, their PFS will be measured up to the date of their last tumor check. This helps to understand if the treatment helps people unable to receive cisplatin live longer without their cancer progressing.

All PD-L1 >= 1% Randomized Participants - Primary Study

This measure looks at how long all participants in the primary study live without their cancer getting worse after being assigned to a treatment group.

Progression-Free Survival (PFS) is defined as the time from when a participant is assigned to a treatment group (randomization) until their cancer is first shown to get worse (progress), based on reviews by independent experts who do not know which treatment the participant received. These experts use standard rules (called RECIST 1.1) to decide if the cancer has progressed. If a participant dies before their cancer is shown to get worse, the date of death will be used as the time their disease progressed. If a participant's cancer does not get worse and they do not die during the study, their PFS will be measured up to the date of their last tumor check.

This helps to understand whether the treatment can help participants live longer without their cancer progressing.

All Randomized Participants - Primary Study

The EORTC QLQ-C30 is a questionnaire used to assess the quality of life in cancer patients. It includes a global health status score, which is measured on a 4-point Likert scale: 1 = not at all, 2 = a little, 3 = quite a bit, and 4 = very much. Responses are combined and converted to scores ranging from 0 to 100. A high score for global health status or health-related quality of life (HRQoL) indicates a high overall HRQoL.

All Randomized Participants - Primary Study

This measure looks at how long people who can receive cisplatin chemotherapy live without their cancer getting worse after being assigned to a treatment group in the sub-study. Progression-Free Survival (PFS) is the time from when a participant is assigned to a group (randomization) until their cancer is first shown to get worse (progress), based on reviews by independent experts who do not know which treatment was given. These experts use standard rules (RECIST 1.1) to decide if the cancer has progressed. If a participant dies before their cancer is shown to get worse, the date of death will be used as the time their disease progressed. If a participant's cancer does not get worse and they do not die during the study, their PFS will be measured up to the date of their last tumor check. This helps to understand if the treatment helps people eligible for cisplatin live longer without their cancer progressing.

All Cisplatin-eligible Randomized Participants - Sub-study

This measure looks at how long people who are able to receive cisplatin (a type of chemotherapy) live after being placed into a treatment group in the sub-study.

Overall Survival (OS) is defined as the time between the date a participant is randomized (assigned to a treatment group) and the date of death from any cause. For participants without documentation of death, OS will be measured up to the last date the participant was known to be alive. If a participant was randomized but had no follow-up information, OS will be counted from the date of randomization.
