Inclusion Criteria:

  • Subject has provided informed consent prior to initiation of any study-specific activities/procedures
  • Subjects with histologically or cytologically confirmed mCRPC who are refractory to a novel antiandrogen therapy (abiraterone, enzalutamide, and/or apalutamide) and have failed at least 1 (but not more than 2) taxane regimens (or who are deemed medically unsuitable to be treated with a taxane regimen or have actively refused treatment with a taxane regimen). Progression on novel antiandrogen therapy may have occurred in the non-metastatic CRPC setting
  • Subject should have undergone bilateral orchiectomy or should be on continuous androgen-deprivation therapy (ADT) with a gonadotropin-releasing hormone (GnRH) agonist or antagonist
  • Total serum testosterone </= 50 ng/dL or 1.7 nmol/L
  • Evidence of progressive disease, defined as 1 or more PCWG3 criteria: PSA level >/=1 ng/mL that has increased on at least 2 successive occasions at least 1 week apart, nodal or visceral progression as defined by RECIST 1.1 with PCGW3 modifications, and/or appearance of 2 or more new lesions in bone scan

Exclusion Criteria:

  • Any anticancer therapy or immunotherapy within 4 weeks of start of first dose, not including luteinizing hormone-releasing hormone agonist (LHRH)/GnRH analogue (agonist/antagonist). Subjects on a stable bisophosphonate or denosumab regimen for >/= 30 days prior to randomization are eligible
  • Prior PSMA-targeted therapy (subjects on prior 177Lu-PSMA-617 therapy may be eligible if discussed with Amgen medical monitor prior to enrollment)
  • Central nervous system (CNS) metastases, leptomeningeal disease, or spinal cord compression
  • Active autoimmune disease or any other diseases requiring immunosuppressive therapy while on study
  • Needing chronic systemic corticosteroid therapy (prednisone > 10 mg per day or equivalent) or any other immunosuppressive therapies (including anti-tumor necrosis factor alpha [TNF alpha] therapies) unless stopped 7 days prior to start of first dose

Part 2 only:

  • Subjects on a prior PD-1 or PD-L1 inhibitor who experienced a Grade 3 or higher immune-related adverse event prior to first day of dosing
  • History or evidence of interstitial lung disease or active, non-infectious pneumonitis

Time Frame: Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication (or other new use) have been granted marketing authorization in both the US and Europe, or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.
Access Criteria: Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s). In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
