Neoadjuvant Lu-177-PSMA-617 in Patients With High Risk Localized Prostate Cancer Undergoing Radical Prostatectomy
What this study is about
Male adults with a confirmed diagnosis of prostate adenocarcinoma who meet criteria for localized high risk prostate cancer according to the NCCN guidelines and who are eligible for prostatectomy will be invited to participate. Criteria for high-risk prostate cancer include patients with preoperative prostate biopsy score of Gleason 8 (GS8) (Grade group 4 \[GG4\]) or higher.
View original scientific description
Male adults with a confirmed diagnosis of prostate adenocarcinoma who meet criteria for localized high risk prostate cancer according to the NCCN guidelines and who are eligible for prostatectomy will be invited to participate. Criteria for high-risk prostate cancer include patients with preoperative prostate biopsy score of Gleason 8 (GS8) (Grade group 4 \[GG4\]) or higher. Patients also need to have a positive PSMA scan on 68-Ga-PSMA-11 PET/CT scan.
Interventions
DRUG
Lu-17-PSMA-617
Lu-17-PSMA-617 administration
Primary outcome measures
Prostate cancer down-staging following treatment with Lu-177-PSMA-617 (PluvictoⓇ) defined by Gleason Grade Group
Time frame: Patients will undergo a PSMA PET/CT scans up to week 11 +/- 30 days prior to radical prostatectomy with pelvic lymph node dissection.
Staging of prostate cancer is based on the correlation to Gleason Grade Group (GG) according to the American Joint Committee on Cancer (AJCC; 8TH edition, 2017) staging system for prostate cancer (see Appendix A). Prostate cancer downstaging is defined as the post-treatment stage less than the pre-treatment stage. Different downstaging thresholds will be applied including: * Complete downstaging (CD) is defined as no visible tumor in surgical sample; * Good response (GR) is defined as downstaging from high risk disease (GG4 or greater) to intermediate risk pathologic disease (GG2 or GG3 disease); and * Very good response (VGR) is defined as downstaging from high-risk disease (GG4 or greater) to low risk pathologic disease (GG1 disease).
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
- Patients age 18 or older.
- Patients with histologically confirmed adenocarcinoma of the prostate.
- Patients with high-risk disease defined as a preoperative prostate biopsy of Gleason Score 8 (GS8) (Grade group 4 \[GG4\]) or higher. Men with evidence of lymph node involvement at or below the bifurcation of the common iliac arteries (cN1) on PET-CT 68Ga-PSMA-11 are eligible.
- Pre-operative, pre-treatment PSMA scan with high expression in prostate confirmed by PET/CT 68Ga-PSMA-11 (greater than liver). Patients must not have any other PET FDG-positive sites outside the prostate.
- Patients who are able and willing to undergo surgery.
- Patients with a life expectancy of greater than 10 years. Life expectancy can be estimated using any 1 of the following tools:
- The Social Security Administration tables: https://www.ssa.gov/OACT/STATS/table4c6.html
- The WHO's Life Tables by country: https://apps.who.int/gho/data/view.main.60000?lang=en
- The Memorial Sloa

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.
