Inclusion Criteria: * Male participant age 18 years or older. * Histologically or cytologically confirmed prostate adenocarcinoma with metastatic castration-resistant disease. * Disease progression by PCWG3 while maintaining castrate testosterone (\<50 ng/dL) with ongoing androgen deprivation therapy or prior orchiectomy. * Documented PSMA and/or PSCA expression by a validated tumor assay; PSMA PET may support target confirmation when applicable. * Prior progression on at least one androgen receptor pathway inhibitor such as abiraterone, enzalutamide, apalutamide, or darolutamide; prior taxane, PARP inhibitor, radioligand therapy, or checkpoint inhibitor is allowed. * ECOG performance status 0 or 1. * Adequate hematologic, renal, hepatic, cardiac, and pulmonary function per protocol laboratory thresholds. * At least one measurable lesion by RECIST 1.1 or evaluable bone-predominant disease by PCWG3. * Life expectancy of at least 12 weeks. * Ability to understand and sign informed consent and willingness to provide required blood and tissue samples. Exclusion Criteria: * Active central nervous system metastases or leptomeningeal disease. * Dominant small-cell or neuroendocrine prostate cancer histology. * Prior gene-modified cellular therapy within 6 months before lymphodepletion, or prior allogeneic transplant requiring ongoing systemic immunosuppression. * Active autoimmune disease requiring systemic treatment or chronic immunosuppression; systemic corticosteroid use greater than 10 mg prednisone equivalent daily within 7 days of lymphodepletion. * Uncontrolled infection, including uncontrolled hepatitis B, hepatitis C, or HIV infection. * Clinically significant cardiovascular disease, symptomatic arrhythmia, recent myocardial infarction, or uncontrolled heart failure. * Unresolved grade 2 or higher toxicity from prior anticancer therapy, except alopecia, stable endocrinopathy, or other protocol-approved exceptions. * Another active malignancy requiring systemic treatment. * Any medical, psychiatric, or laboratory abnormality that, in the investigator's judgment, would increase risk or interfere with study interpretation.
