Study summary

The purpose of this study is to determine whether an investigational immunotherapy nivolumab in combination with ipilimumab or in combination with standard of care chemotherapy is more effective than standard of care chemotherapy alone in treating participants with previously untreated inoperable or metastatic urothelial cancer.

Eligibility

Primary outcome measure(s)

• Overall Survival (OS) in Cisplatin-ineligible Randomized Participants for Primary Study — From the date of randomization to the date of death from any cause, or data cut-off date, whichever occurred first (up to approximately 89 months)
  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.
• Overall Survival (OS) in Programmed Death-Ligand 1 (PD-L1) Positive (≥ 1%) Randomized Participants by Immunohistochemistry (IHC) for Primary Study — From the date of randomization to the date of death from any cause, or data cut-off date, whichever occurred first (up to approximately 89 months)
  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.
• Progression-Free Survival (PFS) by Blinded Independent Central Review (BICR) [Using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1] in Cisplatin-eligible Participants for Sub-study — From the date of randomization to the date of first documented disease progression or death due to any cause, whichever occurs first (up to approximately 89 months)
  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.
