Neoadjuvant High Dose Rate Brachytherapy Prior to Radical Prostatectomy in Patients With Prostate Cancer
What this study is about
This is a Phase I/II trial evaluating the effectiveness of adding neoadjuvant HDR-B prior to RALP for HR-PCa patients with selective AAB for decipher high risk or pathologically node positive patients. Patients with newly diagnosed, histologically confirmed, non-metastatic, HR-PCa who are scheduled to receive RALP will be eligible to participate in the study.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Subjects must have biopsy-confirmed adenocarcinoma of the prostate.
- Subjects must have a negative bone scan and CT scan or PSMA-PET for nodal or metastatic disease.
- Subjects must have one of the following risk factors:
- PSA ≥20 and/or
- Gleason score ≥8 and/or
- Clinical or radiographic stage ≥T3a per AJCC (American Joint Committee on Cancer) 8th Edition Staging Manual and/or

- History of prior pelvic radiation therapy.
- Prostate gland \>70 cc as assessed by MRI or TRUS.
- Baseline IPSS \>15 with medical optimization.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
