  3. Has adequate organ function.
  4. Cohort A: Has histologically confirmed unresectable adenocarcinoma or unresectable metastatic adenocarcinoma of the colon or rectum (histology defined by WHO classification).
  5. Cohort A: Must have received at least 1 and no more than 2 lines of systemic treatment for advanced CRC, with documented progression on most recent prior line of therapy Prior lines of therapy must have included treatment with either a fluoropyrimidine, oxaliplatin and/or irinotecan, an anti-VEGF monoclonal antibody and/or an anti-EGFR monoclonal antibody, if the approved biologic therapy(ies) is available. In addition, per local practice guidelines, qualifies for treatment with Bevacizumab and/or 5-FU/LV. • Participants with dMMR/MSI-H status may be eligible if they have received prior ICI therapy (if an approved ICI(s) is available) and also meet all other criteria related to prior therapies as listed above. • Participants with known targetable genomic aberrations may be eligible if they meet all other criteria related to prior therapies as listed above and have received the following (if the approved biomarker-directed therapy/-ies is/are available): • KRAS G12C mutation, e.g., adagrasib or sotorasib • BRAF V600E mutation, e.g., encorafenib • HER2 amplification, e.g., trastuzumab with another agent (NOTE: participants who received treatment with T-DX1 are excluded) • Participants who received neoadjuvant or adjuvant chemotherapy and experienced disease progression during treatment or within 6 months of the EOT may count this therapy as a line of treatment.
  6. Cohort A: Has at least 1 target lesion per RECIST 1.1, as determined by the investigator. Measurable lesions that have been previously irradiated and have been shown to be progressing following irradiation may be considered as target lesions. NOTE: It is preferable not to have a pathological lymph node as a singular target lesion.
  7. Cohort A: Participants must provide tissue from a biopsy taken from primary cancer or metastatic site. Fresh biopsy is preferred. If a fresh biopsy is not feasible, archival FFPE blocks (preferred) or slides from the most recent biopsy are acceptable (preferably taken after the completion of the participant’s last line of therapy prior to the first dose of study drug). Tissue is required for retrospective B7-H3 expression analysis by IHC and other biomarker evaluations. Exceptions may be granted by the medical monitor if tissue is unavailable.
  8. Cohort B: Histologically or cytologically confirmed adenocarcinoma of the prostate.
  9. Cohort B: Metastatic (stage IVB) disease, excluding participants with metastatic disease restricted to pelvic lymph nodes or rectum.
  10. Cohort B: PSA ≥ 1 ng/mL during the screening period.
  11. Cohort B: Serum testosterone level ≤ 50 ng/dL or 1.7 nmol/L during the screening period. Patients must have undergone bilateral orchiectomy or be on continuous androgen-deprivation therapy with a GnRH agonist or antagonist; this therapy must have been initiated at least 4 weeks prior to randomization and treatment must be continued throughout the study.
  12. Cohort B: Progression on or intolerance to SoC lines of therapy in the mCRPC stage [including, but not limited to, docetaxel, ARPI/ novel hormone therapies (such as enzalutamide, apalutamide, darolutamide), and radio-ligand therapy, etc.]. Participants who have experienced disease progression while receiving NHA in mHSPC are allowed. • If the participant is intolerant to NHA, refuses it, or cannot receive it for other reasons, they may be eligible if they have experienced disease progression after receiving at least one systemic chemotherapy regimen. • First-generation antiandrogen therapy (i.e., bicalutamide, flutamide, nilutamide) are not considered a novel hormonal agent or a chemotherapy regimen. Participants who have taken first-generation antiandrogen therapeutic drugs must have a washout period of at least 28 days before enrolment. • Progressive disease is defined as (at least one of the following): • PSA progression: PSA > 1 ng/mL and 2 consecutive increases in PSA at least 1 week apart (compared to current treatment baseline or the nadir during the treatment period) per PCWG3 criteria; and/or • Progression of soft tissue lesions according to RECIST 1.1 criteria; and/or • Bone lesion progression according to PCWG3 criteria.
  13. Cohort B: Has metastatic prostate cancer that includes: ≥1 measurable soft tissue per RECIST 1.1 (not including regional Lymph Nodes) and/or ≥1 metastatic bone lesion per PCWG3 criteria (not a superscan) on bone scintigraphy, at screening.
  14. Cohort B: Where available, participants should provide an archival tumor sample from the most recent biopsy (FFPE block preferred) of primary cancer or from a metastatic site at screening (preferably taken after the completion of the participant’s last line of therapy prior to the first dose of study drug).
