What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

  • Time periods mentioned: 27 months, 2 years

Only what the study's summary and detailed description on ClinicalTrials.gov say. Time periods may describe the whole study or a part of it — ask the study team what applies to you.

Show the study's own words
  • "Patients will be on the study for a total of up to 27 months, including 2-3 months on active study intervention (HDR-B with RALP 4-8 weeks post HDR-B) and potentially an additional 3 months (AAB)."
  • "Study follow-ups will be performed per-protocol for up to 2 years after surgery."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

In plain language

This study tests high-dose radiation placed inside the prostate before robot-assisted surgery to remove it. It is for people age 40 or older with newly diagnosed, high-risk prostate cancer that has not spread and who plan to have this surgery. Some patients may also receive added hormone-blocking treatment based on a cancer risk test or cancer found in lymph nodes.

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.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Age 40 or older, with a biopsy showing prostate adenocarcinoma, a type of prostate cancer.
  • Scans must show no cancer in lymph nodes or other parts of the body.
  • Must have high-risk cancer: PSA of 20 or more, Gleason score of 8 or more, or stage T3a or higher. You may also qualify with at least two of these: PSA 10–19.9, Gleason score 4+3, stage T2b/T2c, or cancer in at least half of biopsy samples. PSA is a blood marker; Gleason scores and stages describe the cancer.
  • Must freely sign a consent form to join.
  • The study doctor must find you healthy enough for surgery and internal radiation treatment.
  • Must be fully active or able to do light work despite limits on hard physical activity.
  • No other invasive cancer in the past 3 years, unless cancer-free for at least 2 years. Exceptions include non-melanoma skin cancer and noninvasive cancer of the bladder or head and neck.
  • No treatment to lower male hormones in the past 6 months.

Who can't join

  • Scans show cancer has spread to other parts of the body.
  • A doctor says anesthesia, the medicine used during surgery, would be high risk for you.
  • Past radiation treatment to the pelvis.
  • Prostate larger than 70 cubic centimeters on MRI or ultrasound.
  • Urinary symptom score above 15, even after treatment to improve symptoms.
  • Treatment to lower male hormones in the past 6 months. Finasteride is allowed only if stopped more than 3 months before joining.
  • Unable or unwilling to follow the study's rules.

Simplified for readability. The official criteria below are what the study team uses.

Official eligibility criteria

Inclusion Criteria: 1. Subjects must have biopsy-confirmed adenocarcinoma of the prostate. 2. Subjects must have a negative bone scan and CT scan or PSMA-PET for nodal or metastatic disease. 3. 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 * At least two out of four of the following: PSA (Prostate Specific Antigen) 10-19.9, GS (Gleason Score) = 4+3, clinical stage = T2b/T2c, ≥50% positive biopsy cores. 4. Subjects must freely sign informed consent to enroll in the study. 5. Subjects must be medically fit to undergo surgery and HDR-B as determined by the PI. 6. Age ≥ 40 7. ECOG Performance Status (performance status is an attempt to quantify cancer patients\' general well-being and activities of daily life, scores range from 0 to 5 where 0 represents perfect health and 5 represents death): 0-1. 8. No prior invasive malignancy in the past 3-years, except non-melanomatous skin cancer unless disease free for a minimum of 2 years. Carcinoma in-situ of the bladder or head and neck region is permissible. 9. Subjects must not have had prior androgen deprivation therapy in the past 6 months. Exclusion Criteria: 1. Metastatic disease as demonstrated by bone scan, CT scan, MRI of the pelvis, or PSMA-PET. 2. Declared high-risk for anesthesia by attending cardiologist, or other physician. 3. History of prior pelvic radiation therapy. 4. Prostate gland \>70 cc as assessed by MRI or TRUS. 5. Baseline IPSS \>15 with medical optimization. 6. History of androgen deprivation therapy within the past 6 months (except finasteride if discontinued \> 3 mo. prior to enrollment). 7. Unwilling or unable to comply with the study protocol. \-
