Participants will receive xaluritamig intravenously.

Darolutamide

Intervention Type DRUG

Participants will receive darolutamide orally.

Xaluritamig with Abiraterone

Participants will receive xaluritamig in combination with abiraterone. Participants will enter long-term follow-up for up to 3 years from the first dose of study treatment, or until withdrawal of consent, lost to follow-up, or participant death, whichever occurs first.

Group Type EXPERIMENTAL

Xaluritamig

Intervention Type DRUG

Participants will receive xaluritamig intravenously.

Abiraterone

Intervention Type DRUG

Participants will receive abiraterone orally.

Eligibility Criteria

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

Inclusion Criteria

* Participants must have histological, pathological, and/or cytological confirmation of adenocarcinoma of the prostate. Mixed histologies (eg, adenocarcinoma with neuroendocrine component) are not permitted.
* Participants must have at the time of diagnosis:

* De novo mHSPC, defined as metastatic disease with no prior diagnosis of localized prostate cancer AND started androgen deprivation therapy (ADT) (luteinising hormone-releasing hormone \[LHRH\] agonist/antagonist or orchiectomy) with or without androgen receptor pathway inhibitor (ARPI) (defined as abiraterone OR darolutamide) as SOC, first treatment with ADT should be no longer than 12 weeks before screening. Prior docetaxel treatment is not permitted.
* Participants must have at the time of diagnosis:

* High-volume metastatic disease defined as presence of visceral metastasis and/or ≥ 4 bone metastases with at least one outside of the vertebral column and pelvis.
* Documented metastatic disease either by a positive bone scan, or for soft tissue or visceral metastases, either by contrast enhanced abdominal/pelvic/chest computed tomography (CT) or magnetic resonance imaging (MRI) scan.
* PSA not progressing per PCWG3 following the initial PSA nadir after starting ADT.

Exclusion Criteria

* Prior history of central nervous system (CNS) metastases.
* Unresolved toxicities from prior anti-tumor therapy (excluding those related to ongoing ADT and ARPI) not having resolved to Common Terminology Criteria for Adverse events (CTCAE) version 5.0 grade 1 or baseline, with the exception of alopecia or toxicities that are stable and well-controlled AND there is an agreement to allow inclusion by both the investigator and the sponsor.
* Autoimmune disease requiring systemic immunosuppression within the past 2 years.
* Participant with symptoms and/or clinical signs and/or radiographic signs that indicate an acute and/or uncontrolled active or systemic infection within 7 days prior to the first dose of study treatment.
* Prior six-transmembrane epithelial antigen of the prostate 1 (STEAP1)-targeted therapy.
* Prior radioligand therapy (RLT), poly-adenosine diphosphate ribose polymerase (PARP) inhibitor, cytotoxic chemotherapy, aminoglutethimide or ketoconazole for prostate cancer, or any prior systemic biologic therapy, including immunotherapy for prostate cancer.
* Prior enzalutamide or apalutamide within 15 days prior to enrollment.
* Requirement for chronic systemic corticosteroid therapy (prednisone dose greater than 10 mg per day or local equivalent) or any other immunosuppressive therapies (including anti TNFα therapies) unless stopped (with adequate tapering) within 7 days prior to dosing.
* Prior radiotherapy (to the prostate and/or to all visible metastatic lesions in a metastasis-directed therapy approach); palliative radiation within 2 weeks prior to first dose of study treatment is allowed.
