Primary Outcome Measures :
  1. Part 1: Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as Assessed by Investigator [ Time Frame: Up to approximately 5 years ]
    ORR is defined as the percentage of participants in the analysis population who had a Complete Response (CR: Disappearance of all target lesions and no new lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by investigator. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and to specify that intratumoral injection does not render a lesion non-evaluable. Only the Part 1 arms will be analyzed in this outcome measure.

  2. Number of Participants who Experience a Dose-Limiting Toxicity (DLT) [ Time Frame: Up to approximately 4 weeks ]
    DLTs are defined as toxicities that: are possibly, probably, or definitely related to study intervention administration; and meet pre-defined study criteria.

  3. Part 2: Number of Participants Who Experienced One or More Adverse Events (AEs) [ Time Frame: Up to approximately 107 weeks ]
    An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. Only the Part 2 arms will be analyzed in this outcome measure.

  4. Part 2: Number of Participants Who Discontinued Study Intervention Due to an Adverse Event (AE) [ Time Frame: Up to approximately 103 weeks ]
    An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. Only the Part 2 arms will be analyzed in this outcome measure.


Secondary Outcome Measures :
  1. Part 1: Number of Participants Who Experienced One or More Adverse Events (AEs) [ Time Frame: Up to approximately 107 weeks ]
    An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. Only the Part 1 arms will be analyzed in this outcome measure.

  2. Part 1: Number of Participants Who Discontinued Study Intervention Due to an Adverse Event (AE) [ Time Frame: Up to approximately 103 weeks ]
    An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. Only the Part 1 arms will be analyzed in this outcome measure.

  3. Progression-Free Survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as Assessed by Investigator [ Time Frame: Up to approximately 5 years ]
    PFS is defined as the time from first dose of study treatment to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by investigator. 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. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and to specify that intratumoral injection does not render a lesion non-evaluable. Only the Part 1 arms will be analyzed in this outcome measure.

  4. Duration of Response (DOR) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as Assessed by Investigator [ Time Frame: Up to approximately 5 years ]
    For participants who demonstrate a confirmed immune-based Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by investigator, DOR is defined as the time from first documented evidence of CR or PR until disease progression or death. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and to specify that intratumoral injection does not render a lesion non-evaluable. Only the Part 1 arms will be analyzed in this outcome measure.

  5. Progression-Free Survival (PFS) per Response Evaluation Criteria in Solid Tumors 1.1 for Immune-Based Therapeutics (iRECIST) as Assessed by Investigator [ Time Frame: Up to approximately 5 years ]
    PFS is defined as the time from first dose of study treatment to the first documented immune-based confirmed progressive disease (iCPD) or death due to any cause, whichever occurs first as assessed by investigator. Per iRECIST, iCPD is defined as worsening of any existing cause of progression, or the appearance of any other cause of progression, relative to the initial appearance of progressive disease by RECIST 1.1. Only the Part 1 arms will be analyzed in this outcome measure.

    For participants who demonstrate a confirmed immune-based Complete Response (iCR: Disappearance of all target lesions) or an immune-based Partial Response (iPR: ≥30% decrease in the sum of diameters of target lesions) per iRECIST 1.1 as assessed by investigator, DOR is defined as the time from first documented evidence of CR or PR until disease progression or death. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and to specify that intratumoral injection does not render a lesion non-evaluable. Only the Part 1 arms will be analyzed in this outcome measure.

  7. Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors 1.1 for Immune-Based Therapeutics (iRECIST) as Assessed by Investigator [ Time Frame: Up to approximately 5 years ]
    ORR is defined as the percentage of participants in the analysis population who had an immune-based Complete Response (iCR: Disappearance of all target lesions) or an immune-based Partial Response (iPR: ≥30% decrease in the sum of diameters of target lesions) per iRECIST 1.1 as assessed by investigator.

  8. Overall Survival (OS) [ Time Frame: Up to approximately 5 years ]
    OS is defined as the time from randomization to death due to any cause.

  9. Solid Tumors+Liver Metastases Arms: Objective Response Rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as Assessed by Investigator [ Time Frame: Up to approximately 5 years ]
    ORR is defined as the percentage of participants in the analysis population who had a Complete Response (CR: Disappearance of all target lesions and no new lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1 as assessed by investigator. For this study, RECIST 1.1 has been modified to follow a maximum of 10 target lesions and a maximum of 5 target lesions per organ, and to specify that intratumoral injection does not render a lesion non-evaluable.
