What was measured

OS was defined as the time from date of first study treatment to death due to any cause.

Analysis population: Measured in the Full Analysis Set, which included participants who received ≥ 1 dose of each study treatment drug (ie, ≥ 1 dose of both sitravatinib and nivolumab for Cohorts 1 to 8, or ≥ 1 dose each of sitravatinib, pembrolizumab, and enfortumab vedotin for Cohort 9). Per the statistical analysis plan (SAP), Cohort 9 arms are grouped as pre-specified as there was never intent to compare efficacy endpoints across Cohort 9 dose levels.

Groups in this outcome

Cohort 1

Participants with locally advanced or metastatic urothelial carcinoma (UC) with documented disease progression on or after previous anti-programmed cell death (PD)-ligand(L)-1 as most recent treatment, and who were previously treated with a platinum-based chemotherapy were enrolled into Cohort 1. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 120 mg capsules once daily (QD) in 28-day cycles. Nivolumab was received via an intravenous (IV) infusion over approximately 30 minutes (± 5 minutes) at 240 mg once every 2 weeks (Q2W) or 480 mg once every 4 weeks (Q4W), at the discretion of the Investigator and in accordance with the current nivolumab US Prescribing Information (USPI).

Cohort 2

Participants with locally advanced or metastatic UC with documented disease progression on or after previous anti-PD-L-1 as most recent treatment, and who were considered ineligible for platinum-based chemotherapy were enrolled into Cohort 2. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 120 mg capsules QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 3

Participants with locally advanced or metastatic UC with documented disease progression on or after a previous anti PD-(L)1 as the most recent treatment, who previously received (in combination or separately) other selected immunotherapies, and who were previously treated with a platinum-based chemotherapy were enrolled into Cohort 3. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 120 mg capsules QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 4

Participants with locally advanced or metastatic UC with documented disease progression on or after a previous anti-PD-(L)1 as the most recent treatment, who previously received (in combination or separately) other selected immunotherapies, and who were considered ineligible for platinum-based chemotherapy were enrolled into Cohort 4. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 120 mg capsules QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 5

Participants with locally advanced or metastatic UC who had not previously received an anti-PD-(L)1, and who were previously treated with a platinum-based chemotherapy were enrolled into Cohort 5. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 120 mg capsules QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 6

Participants with locally advanced or metastatic UC who had not previously received an anti-PD-(L)1, and who were considered ineligible for platinum-based chemotherapy were enrolled into Cohort 6. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 120 mg capsules QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 7

Participants with locally advanced or metastatic UC with documented disease progression on or after a previous anti PD-(L)1 and antibody-drug conjugate (ADC) (in combination or separately, and in any order), and who were previously treated with a platinum-based chemotherapy were enrolled into Cohort 7. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 100 mg malate capsules, or 120 mg free base capsule formulation QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 8

Participants with locally advanced or metastatic UC with documented disease progression on or after a previous anti PD-(L)1 and ADC (in combination or separately, and in any order), and who were considered ineligible for platinum-based chemotherapy were enrolled into Cohort 8. Participants received sitravatinib in combination with nivolumab. Sitravatinib was received orally via 100 mg malate capsules, or 120 mg free base capsule formulation QD in 28-day cycles. Nivolumab was received via an IV infusion over approximately 30 minutes (± 5 minutes) at 240 mg Q2W or 480 mg Q4W, at the discretion of the Investigator and in accordance with the current nivolumab USPI.

Cohort 9

Participants with locally advanced or metastatic UC who had previously received a PD-(L)1 checkpoint inhibitor (CPI) and a platinum-based chemotherapy were enrolled into Cohort 9, which included a lead-in dose-escalation part. A dose-expansion part was planned, but was not enrolled. During the lead-in dose-escalation part, participants were enrolled to 3 dose levels of sitravatinib in combination with pembrolizumab and enfortumab vedotin. Sitravatinib was received orally via capsules QD in 21-day cycles at doses 35 mg and 70 mg. Pembrolizumab was received as an IV infusion over approximately 30 minutes (± 5 minutes) at 200 mg every 3 weeks (Q3W), in accordance with the current pembrolizumab USPI. Enfortumab vedotin dosing was based on participant weight, starting at 1.25 mg/kg up to 125 mg/kg QD, with a dose de-escalation step to 1 mg/kg. Enfortumab vedotin was received as an IV infusion over approximately 30 minutes (± 5 minutes) on Days 1 and 8 of a 21-day cycle.
