Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Xaluritamig
Participants with metastatic castration-resistant prostate cancer (mCRPC) will be randomized to receive Xaluritamig as an intravenous (IV) infusion.
Xaluritamig
Short-term IV infusion
Cabazitaxel/Abiraterone/Enzalutamide
Participants with mCRPC will be randomized to receive cabazitaxel as an IV infusion, or a second androgen receptor-directed therapy of either abiraterone as oral tablets, or enzalutamide as oral tablets at the investigator's discretion.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Age ≥ 18 years (or ≥ legal age within the country if it is older than 18 years) at the time of signing the informed consent.
* Participant must have histological, pathological, and/or cytological confirmation of adenocarcinoma of the prostate. Mixed histologies (eg, adenocarcinoma with neuroendocrine component) are not permitted.
* mCRPC with ≥ 1 metastatic lesion that is present on baseline computed tomography (CT), magnetic resonance imaging (MRI), or bone scan imaging obtained within 28 days prior to enrollment.
* Evidence of progressive disease, defined as 1 or more PCWG3 criteria:
* Serum PSA progression defined as 2 consecutive increases in PSA over a previous reference value measured at least 1 week prior. The minimal start value is 2.0 ng/mL.
* Soft-tissue progression defined as an increase ≥ 20% in the sum of the diameter (SOD) (short axis for nodal lesions and long axis for non-nodal lesions) of all target lesions based on the smallest SOD since treatment started or the appearance of one or more new lesions or unequivocal progression of existing non-target lesions.
* Progression of bone disease: defined by the appearance of at least 2 new bone lesion(s) by bone scan (as per the 2+2 PCWG3 criteria).
* Participants must have had a prior orchiectomy and/or ongoing androgen-deprivation therapy and a castrate level of serum testosterone (\< 50 ng/dL or \< 1.7 nmol/L).
* Prior progression on at least one ARDT (enzalutamide, abiraterone, apalutamide, darolutamide).
* Prior treatment with only one taxane therapy in the mCRPC setting. Note: Prior treatment with docetaxel in the metastatic hormone-sensitive prostate cancer (mHSPC) setting is permitted; however, participants must have also received one, and only one, taxane therapy in the mCRPC setting.
* Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1.
* Adequate organ function.
* Life expectancy of ≥ 12 weeks per the treating physician's assessment.
Exclusion Criteria
* Prior six transmembrane epithelial antigen of the prostate 1 (STEAP1)-targeted therapy.
* Any anticancer therapy, immunotherapy, or investigational agent within 4 weeks prior to the first dose of study treatment, not including androgen receptor pathway inhibitors (ARPIs) (abiraterone, enzalutamide, darolutamide, apalutamide): minimum washout of 2 weeks prior to the first dose of study treatment and androgen suppression therapy (eg, luteinizing hormone-releasing hormone/gonadotropin-releasing hormone \[LHRH/GnRH\] analogue \[agonist/antagonist\]).
* Prior Prostate-Specific Membrane Antigen (PSMA) radioligand therapy (RLT) within 3 months of the first dose of study treatment unless participants received \< 2 cycles of therapy.
* Prior palliative radiotherapy within 2 weeks of first dose of study treatment. Participants must have recovered from all radiation-related toxicities.
* Concurrent cytotoxic chemotherapy, ARDT, immunotherapy, radioligand therapy, PARP inhibitor, biological therapy, investigational therapy. Note: Prior treatment with a PARP inhibitor is permitted as long as not within 4 weeks before first dose of study treatment.
* Prior radionuclide therapy (Radium-223) within 2 months of first dose of study treatment.
* Treatment with live and live-attenuated vaccines within 4 weeks before the first dose of study treatment.
Disease Related:
* Participants with a history of central nervous system (CNS) metastasis. Note: Participants with treated, asymptomatic, and clinically stable dural metastases are eligible.
* Unresolved toxicities from prior anti-tumor therapy not having resolved to CTCAE version 5.0 events grade above 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.
