|---|---|---|---|
| Primary | Progression-free survival (PFS) (Comparison between arms) | From date of randomization to date of first documentation of progression, symptomatic deterioration, or death due to any cause, assessed up to 3 years | Will compare between participants randomized to the combination of sacituzumab govitecan plus ivonescimab (SG-I) and sacituzumab govitecan (SG) alone. The comparison of PFS will be done using a 1-sided 10% level log-rank test stratified by randomization stratification factors. Binary proportions along with 90% confidence intervals will be estimated for response to be consistent with 1-sided 5% level testing. With 35 participants per arm, binary proportions can be estimated to within 11% with 90% confidence. The distribution PFS will be estimated using the method of Kaplan-Meier. Comparisons of event time distributions between arms will be summarized by hazard ratios and 80% confidence intervals (consistent with 1-sided 10% level testing) from a Cox Proportional hazards model including the stratification factors. |

| Primary | Response rate of SG against historical response rates (Single arm evaluation) | Up to 3 years | Within each treatment arm, the objective is to evaluate if response rates show activity beyond standard of care, which generally would be single agent chemotherapy or docetaxel combined with ramucirumab. With 35 eligible and evaluable participants per arm, the evaluation has 90% exact power to rule out a 10% response rate using a 1-sided 5% level test (the exact level is 5.1% based on design assumptions), if the true response rate were at least 29%. The observation of at least 7 participants with a response (a 20% response rate) would be considered evidence to rule out a 10% response rate. |

| Secondary | Rate of dose-limiting toxicities among participants treated with SG-I in the safety run-in analysis population | During the first cycle of treatment (21 days) | Defined as treatment-related Grade 3 or higher non hematologic toxicity, treatment-related Grade 4 or higher hematologic toxicity, or any Grade of treatment-related toxicity that leads to drug discontinuation. Toxicities will be graded based on Common Terminology Criteria for Adverse Events (CTCAE). |
| Secondary | Response rates | Up to 3 years | Will compare response rates between I with or without SG. |
| Secondary | Response rates | Up to 3 years | Will compare response rates between SG with or without I. |
| Secondary | Overall survival (OS) | From date of randomization to date of death due to any cause, assessed up to 3 years | Will compare between the SG-I and SG arms. The distribution of OS will be estimated using the method of Kaplan-Meier. Comparisons of event time distributions between arms will be summarized by hazard ratios and 80% confidence intervals (consistent with 1-sided 10% level testing) from a Cox Proportional hazards model including the stratification factors. |

| Secondary | Duration of response (DoR) | From date of first documentation of response to date of first documentation of progression, symptomatic deterioration, or death due to any cause among participants who achieve a response, assessed up to 3 years | The distribution of DoR will be estimated using the method of Kaplan-Meier. |
| Secondary | Central nervous system (CNS) PFS | From date of randomization to date of first documentation of progression, symptomatic deterioration, or death due to any cause, assessed up to 3 years | CNS progression is defined as the development of new CNS metastasis or progression of CNS disease requiring either local CNS therapy or a change in systemic cancer therapy. The distribution of CNS PFS will be estimated using the method of Kaplan-Meier. Comparisons of event time distributions between arms will be summarized by hazard ratios and 80% confidence intervals (consistent with 1-sided 10% level testing) from a Cox Proportional hazards model including the stratification factors. |
| Secondary | Frequency and severity of toxicities | During the first cycle of treatment (21 days) | Toxicities will be graded based on Common Terminology Criteria for Adverse Events (CTCAE). Toxicities will be summarized as proportions by item and worst grade reported, among those possible, probably, or likely related to treatment and also grouped overall and as hematologic and non-hematologic toxicities. Any toxicity, with at least 10% true prevalence has a 97% chance of being observed. |
| Secondary | Clinical outcomes by EGFR subgroups | Up to 3 years | Subgroup analyses will be done using a Cox proportional hazards model for time-to-event outcomes and logistic regression for binary endpoints. |
| Secondary | Clinical outcomes by PD-L1 expression subgroups | Up to 3 years | Subgroup analyses (PD-L1 expression \[\< 1% vs 1% or greater\]) will be done using a Cox proportional hazards model for time-to-event outcomes and logistic regression for binary endpoints. |
