Active clinical trials for "Prostatic Neoplasms"

Depending on the cohort of the study the diagnostic and prognostic accuracy and health economics considerations of [18F]-fluoro-5α-dihydrotestosterone (FDHT)- positron emission tomography (PET) and/or circulating tumor cells in prostate cancer patients are studied.

This study is designed to evaluate the safety and efficacy of a single injection of GEN0101 in patients with recurrence of castration resistant prostate cancer. The subjects receive GEN0101 injection 4 times per two weeks (1st intratumoral injection and followed subcutaneous injection) and two weeks of observation as one cycle treatment period. Each subject receive two cycle treatment period. Low dose group: 30,000m NAU per injection of GEN0101 High dose group: 60,000m NAU per injection of GEN0101 Each group included minimal 3 subjects.

Recent studies support the use of Stereotactic Body Radiation Therapy (SBRT) for the treatment of localized prostate cancer (PrCa). SBRT is a way to deliver radiation very precisely allowing higher doses to be delivered with fewer treatments, potentially improving patient outcomes. Cyberknife and Volume Modulated Arc Therapy (VMAT) are accepted SBRT techniques. However, the effects of the specific SBRT treatment technique on patient outcomes have not been evaluated in randomized trials. Although such a trial would be of great interest, patients' willingness to participate is unclear. Multiple patient and clinician factors contribute to the decision to enter a randomized trial. This feasibility study will evaluate patients' willingness to participate in a trial comparing Cyberknife and VMAT SBRT for the treatment of early stage PrCa. Patients accepting enrolment will be randomized to one of the two types of SBRT delivery. Up to 66 patients will be approached, and up to 40 randomized. A questionnaire will help to identify the factors influencing the patient's decision to participate or not. This study will gather information on feasibility, PSA control, patient outcomes and side effects, and will inform the design of a future randomized phase II/III study.

The SPARK trial is testing the use of Kilovoltage Intrafraction Monitoring in prostate cancer patients being treated with Stereotactic Prostate Adaptive Radiotherapy. The researchers expect this trial to result in better targeted prostate cancer patient outcomes with lower toxicity. The potential application of Kilovoltage Intrafraction Monitoring to other tumour sites will pave the way for additional trials with Australasian radiation oncology leading the world.

Prostate cancer is currently the leading newly diagnosed cancer in the industrialized world. Treatment of prostate cancer is highly dependent on the stage of the disease. Current methods for staging of bone metastases are known to be inaccurate. Staging of lymph nodes requires surgery associated with risk of bleeding etc. Prior studies from our department suggest that PET/CT is useful in staging of bone metastases in patients with prostate cancer. The aim of this study is to compare the usefulness of MeAIB PET/CT with current methods for the staging of bone and lymph node metastases in patients with newly diagnosed prostate cancer. Better initial staging will result in better treatment of the individual patient. If we are able to develop a more accurate and non-invasive method of staging patients with undetected metastases on current staging will be spared of the side-effects associated with current treatment and staging- impotence, incontinence, radiation damage, bleeding, infection etc.

A Phase 1/2 multicenter, dose determining, open-label study of ADXS31-142 monotherapy and a combination of ADXS31-142 with Pembrolizumab (MK-3475) in patients with metastatic castration-resistant prostate cancer. Part A will be dose-determining of ADXS31-142 monotherapy. Part B will be dose-determining of ADXS31-142 and Pembrolizumad (MK-3475) in combination. Part B expansion will treat additional patients with the recommended dose from Part B.

The primary safety purpose of this study is to estimate the rates of immediate and long-term high grade (grade 3-5) gastrointestinal and genitourinary side effects during the five years after TrueBeam stereotactic body radiotherapy in low-risk and intermediate-risk prostate cancer patients. The primary efficacy purpose is to compare 5 year biochemical disease free survival rates with TrueBeam to 5 year biochemical diseases free survival rates with dose-escalated external beam radiation therapy.

In this study, up to 21 patients with metastatic prostate cancer will receive UV1 (a therapeutic synthetic peptide vaccine) at different dose levels. The safety and tolerability of UV1 as well as immunological response will be assessed. The purpose of this study is to select a biological dose of peptides for further clinical trials. Main treatment period is completed and reported. Follow-up ongoing.

This Phase I/Ib trial is studying the absorption and metabolism of phytochemicals found in black raspberries in men undergoing surgery for prostate cancer. This knowledge will help us design future chemoprevention studies and assist in making future dietary recommendations for men at high risk for prostate cancer.

Thirty-five men with newly diagnosed, metastatic prostate cancer are scanned with 18F-PSMA 1007 PET/CT at baseline, 3 weeks after the initiation of GnRH-antagonist, at one year and at the time of castration resistant prostate cancer (CRPC). The aim of the study is to classify metastatic lesions into those with PSMA-flare and those without and determine their potential to progress during the follow-up until CRPC.
