What was measured
A DLT was defined as any of the following events considered to be causally related to treatment with sitravatinib in combination with pembrolizumab and enfortumab in the lead-in dose escalation part of Cohort 9 (as pre-specified): hematological DLTs (Grade 4 neutropenia, thrombocytopenia, anemia unexplained by underlying disease, ≥Grade 3 febrile neutropenia or neutropenia with significant clinical sequelae, or any requirement for a platelet transfusion), non-hematological DLTs (≥Grade 4 infusion related reaction, non-hematological toxicity, Grade 3 infusion related reaction that does not resolve within 24 hours, hypertension that cannot be controlled with medical therapy), other Grade 3 non-hematologic toxicity lasting for \>3 days, with exceptions, Grade 2 pneumonitis or colitis, ≥Grade 3 non-hematological laboratory abnormalities, alanine transaminase\>3 x upper limit of normal (ULN) with bilirubin\> 2xULN, and other related toxic effects may have been assessed as DLTs.
Analysis population: Measured in the DLT evaluable population, which, as pre-specified in the statistical analysis plan, was defined as participants who enrolled in the lead-in dose escalation portion of Cohort 9, who experienced a DLT or who cleared the DLT period.
Groups in this outcome
Cohort 9 Dose Level 1
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 in Cohort 9 Dose Level 1 were enrolled to receive sitravatinib 35 mg QD orally via capsules in 21-day cycles, enfortumab vedotin 1.25 mg/kg IV infusion on Days 1 and 8 every 3 weeks (Q3W), and pembrolizumab 200 mg Q3W as an IV infusion.
Cohort 9 Dose Level 2
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 in Cohort 9 Dose Level 2 were enrolled to receive sitravatinib 35 mg QD orally via capsules in 21-day cycles, enfortumab vedotin 1.0 mg/kg IV infusion on Days 1 and 8 Q3W, and pembrolizumab 200 mg Q3W as an IV infusion.
Cohort 9 Dose Level 3
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 in Cohort 9 Dose Level 3 were enrolled to receive sitravatinib 70 mg QD orally via capsules in 21-day cycles, enfortumab vedotin 1.0 mg/kg IV infusion on Days 1 and 8 Q3W, and pembrolizumab 200 mg Q3W as an IV infusion.
