About this study

Official title: Rezvilutamide Combined With Radical Prostatectomy and Metastasis-Directed Radiotherapy in Oligometastatic Prostate Cancer Patients: A Multicenter, Three-Arm, Open-Label, Randomized Controlled Phase II Clinical Trial

Prostate cancer represents the second most common malignancy in men worldwide. Oligometastatic prostate cancer (OMPC), defined as a transitional state between localized and widespread metastatic disease (≤10 metastatic lesions without visceral metastases), exhibits relatively indolent biological behavior, offering a window for curative-intent multimodal therapy. While standard systemic therapy with androgen deprivation therapy (ADT) plus novel hormonal agents (NHA) remains the backbone for metastatic hormone-sensitive prostate cancer (mHSPC), emerging evidence suggests that maximal cytoreductive therapy-combining systemic treatment with local interventions (Radical prostatectomy(RP) and Metastasis-directed radiotherapy(MDT))-may improve survival outcomes. Rezvilutamide (SHR3680), a novel androgen receptor inhibitor independently developed by a Chinese pharmaceutical company, has demonstrated superior radiographic progression-free survival (rPFS) and overall survival (OS) compared to bicalutamide in high-volume mHSPC (CHART study). However, the value of adding metastasis-directed radiotherapy (MDRT) to rezvilutamide and radical prostatectomy in OMPC remains unproven. This trial hypothesizes that maximal cytoreductive therapy (systemic therapy + surgery + MDRT) will significantly prolong progression-free survival (PFS) compared to systemic therapy alone.

This is a multicenter, three-arm, open-label, randomized controlled phase II clinical trial (Protocol No.: MA-PCa-II-023; Lead Investigator: Prof. Bo Dai, Fudan University Shanghai Cancer Center). The study will enroll 300 patients randomized in a 2:2:1 ratio to:

Arm A (Experimental): Rezvilutamide (240 mg QD) + ADT → radical prostatectomy at month 3 (if PSA decline ≥50%, castrate testosterone level, and resectable disease) → MDT (SBRT 30-40 Gy/3-5 fractions) to all evaluable metastases at month 6 ( 3 month post-surgery)

Arm B (Control): Rezvilutamide (240 mg QD) + ADT alone

Arm C (Factorial): Rezvilutamide (240 mg QD) + ADT → radical prostatectomy at month 3 (without MDT)

Eligible patients are males ≥18 years with histologically confirmed prostate adenocarcinoma (no neuroendocrine differentiation), newly diagnosed mHSPC with oligometastatic disease (≤10 bone/lymph node metastases on conventional imaging; no visceral metastases), and planned ADT. Key exclusion criteria include prior radical prostatectomy, pelvic radiotherapy, systemic therapy for prostate cancer (except ≤4 weeks of ADT), or contraindications to surgery/radiotherapy.

The primary endpoint is PFS, defined as time from randomization to first biochemical progression (PSA rise ≥25% and ≥1 ng/mL above nadir confirmed after ≥3 weeks), radiographic progression (RECIST 1.1/PCWG4), clinical progression (new symptoms from local/metastatic disease), or death. Secondary endpoints include rPFS, OS, PSA response rates (PSA50/PSA90), local therapy completion rate, time to CRPC, quality of life (FACT-P and EPIC-26 questionnaires), and safety profiles. Exploratory endpoints evaluate the role of baseline PSMA PET/CT in staging and the development of artificial intelligence models using multimodal data (clinical, imaging, pathology, molecular) to predict prognosis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-free survival (PFS)

    Time from randomization to the first occurrence of biochemical progression, radiographic progression, clinical progression, or death.

    Biochemical progression: (1) For patients with PSA decline from baseline: PSA increase ≥25% and ≥1 ng/mL above nadir, confirmed by repeat testing ≥3 weeks later; or (2) For patients without PSA decline: PSA increase ≥25% and ≥1 ng/mL above baseline after ≥12 weeks of treatment.

    Radiographic progression: Disease progression per RECIST 1.1 (soft tissue) and PCWG4 (bone) criteria.

    Clinical progression: New symptoms due to local disease progression, lymph node involvement, or systemic metastases (e.g., pathologic fracture, spinal cord compression, worsening pain unresponsive to symptomatic treatment).

    Measured: up to 72 months

Secondary outcomes (7)
  1. Radiographic PFS (rPFS)

    Time from randomization to first radiographic disease progression (RECIST 1.1 for soft tissue; PCWG3 for bone) or death.

    Measured: up to 72 months

  2. Overall Survival (OS)

    Time from randomization to death from any cause.

    Measured: up to 72 months

  3. PSA Response Rates

    Proportion of patients achieving PSA50 (≥50% decline), PSA90 (≥90% decline), or undetectable PSA (<0.2 ng/mL).

    Measured: up to 72 months

  4. Local Therapy Completion Rate

    Proportion of patients in experimental arms completing all planned local therapies (surgery ± radiotherapy).

    Measured: up to 72 months

  5. Time to CRPC

    Time from randomization to castration-resistant prostate cancer (disease progression per PSA or imaging criteria despite castrate testosterone levels <50 ng/dL).

    Measured: up to 72 months

  6. 3-Year PSA Progression-Free Survival Rate

    Proportion of patients without PSA progression at 3 years.

    Measured: up to 72 months

  7. Time to PSA Progression

    Time from randomization to PSA progression (same criteria as biochemical progression in PFS).

    Measured: up to 72 months

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 24 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Bo Dai, MD (+86-21 64175590, bodai1978@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free survival (PFS) (time frame: up to 72 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Mar 2026.
