Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Eastern Cooperative Oncology Group (ECOG) performance status ≤1.
2. Metastatic prostate adenocarcinoma without small-cell carcinoma or neuroendocrine features.
3. Prior therapy with a second-generation androgen receptor (AR)-targeted therapy (e.g., abiraterone, enzalutamide, apalutamide, darolutamide).
4. Prior therapy with a taxane regimen or are considered ineligible for treatment with a taxane regimen or have refused treatment with a taxane regimen, unless otherwise specified.
5. For participants with a known pathogenic breast cancer gene 1 (BRCA1) or BRCA2 mutation: prior therapy with a poly (adenosine diphosphate (ADP)-ribose) polymerase (PARP) inhibitor, or are considered ineligible for treatment with a PARP inhibitor, if such therapy is approved and available.

Exclusion Criteria

1. Treatment with any approved systemic anti-cancer therapy within 14 days or 5 drug elimination half-lives (whichever is longer, not to exceed 28 days) prior to the first study treatment.
2. Treatment with any investigational agent within 28 days prior to the first study treatment.
3. Treatment with any previous AR protein degrader.
