Filter by:The goal of this study type: observational study (prospective study) is to study prostate cancer occurrence and recurrence, to specifically identify and localize tumor foci at the molecular level at an early stage, to evaluate the prognosis of patients, and to accurately stage not only intermediate- and high-risk prostate cancer patients with a primary diagnosis, but also detect recurrent foci in patients with biochemical recurrence, to restage those who have developed metastases, to assess tumor load, and to ultimately assist in determining the personalized treatment plans. The main question it aims to answer is whether 68Ga-PSMA PET/CT (PET/MR) examination is beneficial for assessing the - Accurate staging of patients with intermediate- and high-risk prostate cancer at first diagnosis; - Detecting recurrent lesions in patients with recurrent tumors for re-staging; - Assessment of tumor load; - Assessment of patient prognosis. Participants will sign an informed consent form, undergo 68Ga-PSMA PET/CT (PET/MR) before surgery or biopsy, and have regular follow-up after obtaining pathological results of surgical resection or puncture biopsy, 6 weeks after surgery or biopsy, and then every 3 months; the follow-up will include: blood PSA, whole-body bone imaging, etc.
The VOYAGER Study is an interventional, non-randomized, single-arm, dose escalation trial with the goal of determining the safety of TheraSphere PCa device in patients with clinically localized prostate cancer across US-based centers.
There has been literature demonstrating the effectiveness of correcting these MRI images by using an additional measurement of the magnetic field, but the implied improvement in lesion detection in these common distorted regions in the prostate has yet to be shown. We propose that introducing this distortion correction would greatly improve the DWI images used for tumour detection. For this study we propose testing this hypothesis as a primary objective, and as a secondary objective including additional b-values to further refine the ADC value. The study involves adding one additional distortion correcting scan to the standard clinical study, adding approximately 2 minutes to the study.
The purpose of this study is to determine the proportion of men with residual/recurrent clinically significant prostate cancer (Grade Group ≥2 disease) in the ablated or unablated prostate tissue following the combination treatment of 6-months of androgen deprivation therapy, apalutamide, and partial ablation of the prostate in men with newly diagnosed non-metastatic intermediate risk prostate cancer; specifically, men with a histopathologic diagnosis of Grade Group 2 & 3, with prostate specific antigen level <20 ng/mL. And to assess the safety of the combination treatment of androgen deprivation therapy, apalutamide, and partial ablation of the prostate for the management of these patients.
This phase II trial tests whether magnetic resonance imaging (MRI)-guided hypofractionated radiation therapy works to reduce treatment time and side effects in patients with high risk prostate cancer. MRI-guided hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time directly to diseased tissue, reducing damage to healthy tissue. Using MRI-guided radiation therapy on areas of the prostate and pelvic lymph nodes may shorten overall treatment time compared to the longer standard of care therapy and may reduce the number and/or duration of side effects.
This is phase I, open label, multicentre, dose-escalation study where both doses of talazoparib and pidnarulex will be escalated to define the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) for the combination. It is possible that either 1 or 2 RP2D of the combination will be defined at the end of the study. Patients with disease that is deemed to be amendable to repeated tumour biopsies will be invited to undergo optional paired biopsies: at baseline and Cycle 1 Day 9 + 3 days and at the time of progression. Pidnarulex will be given as an IV infusion on days 1 and 8 of a 28 day cycle and talazoparib will be taken once daily continuously. Disease status will be assessed at regular intervals by CT scans, radionuclide bone scans, and PSA. Throughout the study, safety and tolerability will be assessed and established procedures for management of toxicities will be applied
This clinical trial tests whether it is feasible to use the OmnEcoil system for transrectal magnetic resonance imaging (MRI) to visualize and biopsy suspicious lesions in the prostate. The OmnEcoil device combines an endorectal coil (a type of wire placed within the rectum during diagnostic endorectal MRI to take better images of the prostate) with an endorectal probe. The OmnEcoil system is designed to allow for MRI to be used at the same time to image the prostate and aid in the biopsy of the suspected prostate cancer. Usually, these are performed as two separate events at two separate times.
This is a phase 2, multicenter, open-label study to evaluate the efficacy of abivertinib with abiraterone in patients with metastatic castration-resistant prostate cancer.
The purpose of this study is to utilize this technology in the early detection and staging of pathologic states within prostate cancer patients using the information obtained on mpMRI and serum biomarkers from the patient's blood (if collected). Ultimately, investigators hope to improve the diagnostic accuracy and treatment selection process for these patients. Applying the fusion software which adds mpMRI to ultrasound images in real time, to an otherwise clinically standard but non-targeted ultrasound-guided prostate biopsy procedure will help with accurate and early diagnosis of prostate cancer.
This is a phase I/II dose-escalation study of 225Ac-J591 administered together with 177Lu-PSMA-I&T (also known as PNT2002). The two study drugs are 225Ac-J591 and 177Lu-PSMA-I&T. Both drugs are designed to deliver radiation to prostate cancer cells; they are known as radionuclide conjugates (radiation linked to antibodies/molecules that recognize prostate cancer cells). The first phase of the study (phase I) will determine the highest dose of the study drug that can be safely given. The second phase of the study (phase II) will determine the effectiveness of the drug combination in patients with prostate cancer.
