Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Efficacy Phase: Number of Participants Who Experience One or More Dose-Limiting Toxicities (DLTs) - Combination Arms Only | Up to approximately 21 days | The following events if considered drug related by the Investigator, will be considered a DLT: Grade 4 nonhematologic toxicity (not based on laboratory value); Grade 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia; Grade 4 thrombocytopenia of any duration; Grade 3 thrombocytopenia associated with clinically significant bleeding; Nonhematologic AEs ≥Grade 3 with exceptions; Grade 3 or Grade 4 non-hematologic laboratory values if requires medical intervention, leads to hospitalization, persists for \>1 week, or results in a Drug-induced Liver Injury with exceptions; Grade 3 or 4 febrile neutropenia; Study intervention - related toxicities that lead to discontinuation of study treatment during Cycle 1; Prolonged delay (\>2 weeks) in initiating Cycles 2 due to treatment-related toxicity; Missing \>25% of study intervention doses as a result of treatment-related AE during Cycle 1; Grade 5 toxicity. |
| Primary | Efficacy Phase: Number of Participants Who Experienced an Adverse Event (AE) | Up to approximately 54 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. |
| Primary | Efficacy Phase: Number of Participants Who Discontinued Study Intervention Due to an AE | Up to approximately 24 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. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. |
| Primary | Efficacy Phase: Prostate-Specific Antigen (PSA) response rate | Up to approximately 54 months | PSA response is defined per prostate cancer working group (PCWG) criteria as a reduction in the PSA level of 50% or more from baseline measured at consecutive assessments at least 3 weeks apart. |
| Primary | Safety Lead-in Phase: Number of Participants Who Experience One or More Dose-Limiting Toxicities (DLTs) - Combination Arms Only | Up to approximately 21 days | The following events if considered drug related by the Investigator, will be considered a DLT: Grade 4 nonhematologic toxicity (not based on laboratory value); Grade 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia; Grade 4 thrombocytopenia of any duration; Grade 3 thrombocytopenia associated with clinically significant bleeding; Nonhematologic AEs ≥Grade 3 with exceptions; Grade 3 or Grade 4 non-hematologic laboratory values if requires medical intervention, leads to hospitalization, persists for \>1 week, or results in a Drug-induced Liver Injury with exceptions; Grade 3 or 4 febrile neutropenia; Study intervention - related toxicities that lead to discontinuation of study treatment during Cycle 1; Prolonged delay (\>2 weeks) in initiating Cycles 2 due to treatment-related toxicity; Missing \>25% of study intervention doses as a result of treatment-related AE during Cycle 1; Grade 5 toxicity. |

An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. |
| Secondary | Objective Response Rate (ORR) | Up to approximately 54 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 PCWG3-Modified Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented. |
| Secondary | Radiographic Progression-Free Survival (rPFS) | Up to approximately 54 months | rPFS is defined as the time from randomization to the first documented progressive disease (PD) per PCWG3-modified RECIST 1.1 based on BICR or death due to any cause, whichever occurred first. Per PCWG3-modified 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 have demonstrated an absolute increase of ≥5 mm. The appearance of one or more new lesions or ≥2 new bone lesions was also considered PD. PCWG3-modified RECIST is similar to RECIST 1.1 with the exception that a confirmation assessment of PD (\>4 weeks after the initial PD) is required for participants who remain on treatment following a documented PD per RECIST 1.1 and PCWG3 rules include new bone lesions. The rPFS per PCWG3-modified RECIST as assessed by BICR for all participants is presented. The nonparametric Kaplan-Meier method will be used to estimate the rPFS curve in each treatment arm |
| Secondary | Overall Survival (OS) | Up to approximately 54 months | Overall survival (OS) is defined as the time from randomization to death due to any cause. The nonparametric Kaplan-Meier method will be used to estimate the survival curves. |
