Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Part 1 (FP and TP Safety Run-in): Number of Participants With Dose Limiting Toxicities (DLTs) | Up to 21 days | A DLT is defined as a specific adverse event graded for toxicity using the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Hematologic DLTs are defined as Grade 4 neutropenia lasting for ≥7 days, Grade 3 or Grade 4 febrile neutropenia, Grade 3 thrombocytopenia with bleeding, Grade 4 thrombocytopenia, or Grade 4 anemia. Other nonhematologic toxicities considered a DLT include any other Grade 4 or Grade 5 toxicity, Grade 3 toxicities lasting \>3 days (excluding nausea, vomiting, and diarrhea controlled by medical intervention within 72 hours, and Grade 3 rash in the absence of desquamation with no mucosal involvement), Grade 3 hypertension not able to be controlled by medication, ≥Grade 3 gastrointestinal perforation, ≥Grade 3 wound dehiscence requiring medical or surgical intervention, any grade thromboembolic event or any Grade 3 nonhematologic laboratory value requiring medical intervention or hospitalization. The number of participants in Part 1 with DLTs are presented. |
| Primary | Part 1 (FP and TP Safety Run-in): Number of Participants With Adverse Events (AEs) | Up to 43 months | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants in Part 1 with AEs will be presented. |
| Primary | Part 1 (FP and TP Safety Run-in): Number of Participants Who Discontinued Study Treatment Due to an AE | Up to 22 months | An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants in Part 1 who discontinue study treatment due to an AE will be presented. |
| Primary | Part 2 (Main Study): Overall Survival (OS) in All Participants | Up to 42 months | OS is defined as the time from randomization to death due to any cause. OS in Part 2 for all randomized participants are presented based on the Kaplan-Meier method for censored data. |
| Secondary | Part 2 (Main Study): Progression-free Survival (PFS) Per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) as Assessed by Blinded Independent Central Review (BICR) in All Participants | Up to 42 months | PFS is defined as the time from randomization to the first documented progressive disease (PD) per RECIST 1.1 by BICR or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. RECIST 1.1 has been adjusted to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. PFS in Part 2 for all randomized participants are presented based on the Kaplan-Meier method for censored data. |
| Secondary | Part 2 (Main Study): Objective Response Rate (ORR) Per RECIST 1.1 as Assessed by BICR in All Participants | Up to 42 months | ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions), per RECIST 1.1 adjusted to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, as assessed by BICR. ORR in Part 2 for all randomized participants are presented. |
| Secondary | Part 2 (Main Study): Duration of Response (DOR) Per RECIST 1.1 as Assessed by BICR in All Participants | Up to 42 months | For participants who demonstrate a confirmed CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions), per RECIST 1.1 by BICR, DOR is defined as the time from first documented evidence of CR or PR until PD or death. Per RECIST 1.1, PD is defined as at least a 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions is also considered PD. RECIST 1.1 has been adjusted to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. DOR in Part 2 for all randomized participants are presented based on the Kaplan-Meier method for censored data. |
| Secondary | Part 2 (Main Study): OS in Participants With Programmed Cell Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10 | Up to 42 months | OS is defined as the time from randomization to death due to any cause. OS in Part 2 for randomized participants with PD-L1 CPS ≥10 are presented based on the Kaplan-Meier method for censored data. |
| Secondary | Part 2 (Main Study): PFS Per RECIST 1.1 as Assessed by BICR in Participants With PD-L1 CPS ≥10 | Up to 42 months | PFS is defined as the time from randomization to the first documented PD per RECIST 1.1 by BICR or death due to any cause, whichever occurs first. Per RECIST 1.1, PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. RECIST 1.1 has been adjusted to include a maximum of 10 target lesions and a maximum of 5 target lesions per organ. PFS in Part 2 for randomized participants with PD-L1 CPS ≥10 are presented based on the Kaplan-Meier method for censored data. |
| Secondary | Part 2 (Main Study): ORR Per RECIST 1.1 as Assessed by BICR in Participants With PD-L1 CPS ≥10 | Up to 42 months | ORR is defined as the percentage of participants with CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions), per RECIST 1.1 adjusted to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, as assessed by BICR. ORR in Part 2 for randomized participants with PD-L1 CPS ≥10 are presented. |
