Phase 3RecruitingSWOG Cancer Research NetworkNCT03678025Data as of May 2026

Treatment: Abiraterone · Bicalutamide · Degarelix · Docetaxel · Flutamide · Goserelin Acetate · Histrelin Acetate · Leuprolide Acetate · Nilutamide · Prednisone · TriptorelinThis phase III trial studies how well standard systemic therapy with or without definitive treatment (prostate removal surgery or radiation therapy) works in treating participants with prostate cancer that has spread to other places in the body. Addition of prostate removal surgery or radiation therapy to standard systemic therapy for prostate cancer may lower the chance of the cancer growing or spreading.

Prior therapy

Must have received: standard systemic therapy — metastatic

Patients must have received between 22 and 28 weeks of SST as measured from the date of first hormonal therapy or surgical castration. SST is defined by current NCCN guidelines for metastatic prostate cancer.

Cannot have received: local therapy for prostate adenocarcinoma (brachytherapy, high-intensity focused ultrasound, cryotherapy, laser ablative therapies)

Exception: prior therapy for benign conditions allowed

No prior local therapy for prostate adenocarcinoma is allowed (e.g., brachytherapy, high-intensity focused ultrasound [HIFU], cryotherapy, laser ablative therapies). Any prior therapy for benign conditions, such as obstruction, are acceptable (e.g., transurethral resection of the prostate, greenlight laser ablation, microwave ablation).

Cannot have received: docetaxel (docetaxel)

Exception: not allowed after randomization

Patients must not be planning to receive docetaxel after randomization.
