Beschreibung
Inclusion Criteria:
- Participants ≥18 years of age
- Has histologically or cytologically confirmed adenocarcinoma of the prostate.
- Has an Eastern Cooperative Oncology Group (ECOG) PS of 0 or 1, with no deterioration in the 2 weeks before randomization.
- Has a life expectancy of at least 4 months.
- Has adequate organ function
Exclusion Criteria:
- Pathological finding consistent with small cell, neuroendocrine carcinoma of the prostate, mixed histologies or any histology different from adenocarcinoma.
- Participants with known mismatch repair deficient (dMMR)/MSI-H/TMB-H status and eligible for immune checkpoint inhibitor therapy,
- Has a malignancy (except disease under study) that has progressed or required active treatment within the past 24 months except for basal cell or squamous cell carcinomas of the skin or in-situ carcinomas [e.g., breast, cervix] with no evidence of metastatic disease.
- Has undergone major surgery, including local prostate intervention (except prostate biopsy), within 28 days before the date of randomization,
- Has clinically significant bleeding symptoms or significant bleeding tendency within 1 month prior to the first dose.
- Known active infectious diseases requiring systemic treatment or known human immunodeficiency virus (HIV)
- Has untreated brain or central nervous system (CNS) metastases or brain/CNS metastases that have progressed
- Has received systemic immunosuppressive agents within 30 days prior to first dose of study intervention (or requires long-term administration [30 days or longer]).
- Has received any prior therapy with an ADC with a topoisomerase 1 inhibitor (TOPO1-inhibitor) payload
