PSMA-Targeted Intraoperative Fluorescent Imaging Agents (DGPR1008): Validation Across Different Time Windows

a Phase II, single-arm, open-label, multi-center study to evaluate safety, tolerability, pharmacokinetics, and the effectiveness of near-infrared fluorescence imaging during surgery.

Limited Versus Extended Lymph Node Dissection During Radical Prostatectomy in Patients With Localized or Locally Advanced Prostate Cancer

This is a randomized controlled study assessing outcome of low (no or limited) versus high (limited or extended) extent of lymph node dissection in addition to radical prostatectomy in patients with operable localized or locally advanced prostate cancer.

Ejaculatory Behavior and Seminal Vesicle Size During Radical Prostatectomy

The goal of this clinical trial is to learn if recent ejaculation or abstinence before surgery affects seminal vesicle size and dissection-related surgical factors in adult men with prostate cancer undergoing radical prostatectomy. The main questions it aims to answer are: Does ejaculation within 36 hours before surgery reduce seminal vesicle size compared to abstinence of 72 hours or more? Does seminal vesicle size affect the ease or difficulty of surgical dissection during radical prostatectomy? Researchers will compare an ejaculation group to an abstinence group to see if seminal vesicle volume and intraoperative surgical parameters differ between them. Participants will: Follow specific instructions to either ejaculate or abstain before surgery Undergo a transrectal ultrasound (TRUS) to measure seminal vesicle size after anesthesia but before surgery Have their surgical dissection time and difficulty rated by the operating surgeon

FK-PC101 as Adjuvant Therapy for Men With High-Risk Prostate Cancer

The goal of this clinical trial is to learn if the vaccine FK-PC101 works to delay or prevent the return of prostate cancer in men who have had surgery to remove their prostate cancer. It will also learn about the safety of FK-PC101. The main questions it aims to answer are: Does FK-PC101 delay or prevent the return of prostate cancer following surgery? What medical problems do participants (subjects) have when taking FK-PC101? Researchers will compare FK-PC101 to current treatment practice to see if FK-PC101 works to prevent or delay the return of prostate cancer following surgery to remove the prostate cancer tumor. Subjects will: Have a sample of the prostate cancer tissue collected at the time of surgery to remove this tissue from the body. This tissue will then be used to create a personalized vaccine that is specific to your prostate cancer. If randomly selected to receive the vaccine, subjects will receive the vaccine up to 7 times over a 6-month period. In addition to the treatment visits for those randomized to receive FK-PC101, there will be up to 4 follow up visits to the clinic over a 22-month (nearly 2 year) period. For subjects randomized to receive current treatment practice, they will be asked to attend up to 8 visits over 22 months to track if there is any detectable cancer. Should their prostate cancer return within a year following surgery, they will be eligible to receive FK-PC101, which already had been produced and thus no additional tumor tissue would need to be obtained. Subjects in both study arms will have regular blood tests and scans to test whether their prostate cancer has returned.
