NCT07460726
This study looks at how combined radiation and hormone therapy affects sexual function in men with a specific type of prostate cancer, before and after treatment.
NCT06616597
To determine if dexamethasone or dexamethasone plus metronidazole restore sensitivity to abiraterone for the treatment of metastatic prostate cancer.
NCT07115914
This study is about adding PSMA PET (Prostate Specific Membrane Antigen- Positron Emission Tomography) to routine magnetic resonance imaging (MRI) scans to help detect prostate cancer recurrence in men who have undergone focal therapy for prostate cancer. PSMA PET and multiparametric (mpMRI are both imaging tests that help detect prostate cancer in the body. A PSMA PET scan, or prostate-specific membrane antigen positron emission tomography scan, is an imaging test that scans and takes pictures of the prostate. PSMA scans use a specialized radioactive imaging dye that sticks to the proteins that are typically found in prostate cancer cells. This imaging dye helps locate areas of prostate cancer anywhere in the body, both inside and outside prostate. An mpMRI, or a multiparametric (mp) MRI scan, is also an imaging test that scans and takes detailed pictures of the prostate. Unlike regular MRIs, an mpMRI produces a more detailed image of the prostate. Similar to PET scans, mpMRI scans also use an imaging dye that helps the pictures of the prostate appear clearer on scans. This study will be funded by Blue Earth Diagnostics, a molecular imaging company based in England.
NCT07391982
The goal of this clinical trial is to find out whether lowering the radiation dose to parts of the prostate without visible tumor on MRI can reduce side effects while still effectively treating prostate cancer in men with low or intermediate-risk prostate cancer. The main questions it aims to answer are: * Does reducing the radiation dose to healthy prostate tissue lower the risk of bowel and urinary side effects? * Can we maintain good cancer control by keeping a high dose for MRI-visible tumor areas? Researchers will compare two treatment approaches: * One group receives a uniform high dose to the entire prostate. * The other group receives a lower dose to healthy prostate tissue and a high dose only to visible tumor areas. Participants will: * Receive two sessions of MRI-guided radiotherapy using an MR-Linac. * Complete questionnaires about urinary, bowel, and sexual health before and after treatment. * Have follow-up visits to monitor side effects and PSA levels for up to 2 years.
NCT07316686
This is a Phase I, open-label, single-center study evaluating the safety, tolerability, and recommended Phase II dose of docetaxel when combined with a fixed dose of 177-Lutetium-PSMA-I\&T in chemotherapy-naïve patients with metastatic castration-resistant prostate cancer (mCRPC). Patients will receive standard androgen deprivation therapy, docetaxel at escalating doses (50 mg/m², 60 mg/m², 75 mg/m² every 3 weeks), and 177Lu-PSMA-I\&T at a fixed dose of 7.4 GBq every 6 weeks (up to 4 cycles). A 3+3 dose escalation design will be employed. Secondary endpoints include safety profile, treatment-limiting toxicities, treatment completion rate, and delayed toxicity. Exploratory endpoints include PSA response, radiographic progression-free survival (rPFS), and PERCIST-based response rate.

The TA-P-OLIM Study (Percutaneous Thermo-Ablation of Prostate Cancer OligoMetastasis) is a prospective, interventional phase II study designed to evaluate the feasibility, efficacy, and safety of percutaneous thermal ablation (TA) as a metastasis-directed therapy (MDT) for patients with oligometastatic prostate cancer. So far, these metastases have been locally treated with stereotactic body radiation therapy (SBRT) or surgical resection. Percutaneous TA is a minimally invasive technique that locally destroys tumor tissue using either heat (via microwave or radiofrequency ablation) or cold (via cryoablation). This is achieved by inserting specialized needles into the tumor through a small skin incision under image guidance. TA offers a valuable treatment option for patients who are not suitable candidates for SBRT, such as those with prior radiation exposure or metastases located near critical anatomical structures. In many of these cases, ablation remains feasible through the use of adjunctive thermoprotection techniques, where fluid is injected via a needle to gently displace critical structures, thereby creating a safe buffer zone during treatment. Preliminary retrospective evidence shows that TA achieves comparable local tumor control rates to SBRT/resection with minimal complications.7 As a minimally invasive procedure, TA typically requires only a brief hospital stay-often on an outpatient basis-and enables rapid recovery. This makes TA an attractive alternative to surgery, which is associated with greater morbidity, longer recovery times, and limited suitability for some patients. In contrast to SBRT, TA also allows for simultaneous tissue sampling which is completed in a single session. Moreover, it can be safely repeated in the event of local recurrence. The study focuses on patient-centered endpoints such as local control and tolerability, aiming to improve quality of life through personalized, minimally invasive treatment strategies. TA also offers an effective local treatment option for patients who are not eligible for standard treatments such as SBRT. In this way, an alternative to both SBRT and surgery is provided, enabling continued local treatment for patients. Patients are eligible if they have previously received radical treatment for prostate cancer (surgery or radiotherapy, with or without hormonal therapy), subsequently developed a limited number of metastases (1-5), and are no longer candidates for or deny SBRT. UZ Ghent, with its long-standing research expertise in metastasis-directed therapies for oligometastatic prostate cancer, coordinates the study. The project was established in collaboration with various departments within the Urological Multidisciplinary Tumor Board. Several centers in East and West Flanders have already confirmed their willingness to participate in the study.

The purpose of this study is to assess detection rate of flotufolastat F 18 positron emission tomography (PET) for low prostate specific antigen (PSA) recurrence of prostate cancer (PC) following radical prostatectomy.
NCT06931496
The investigators are interested here in the contribution of a new prostate cancer screening method and, more specifically, in the new and somewhat futuristic approach of artificial intelligence in the development of new, more accurate algorithms that make it possible to rethink the benefits of mass generalisation of prostate biopsies. Main objective The main objective of this research is to use artificial intelligence and an associated algorithm to identify new indicators that would make it possible to avoid a prostate biopsy in patients with an initial suspicion of prostate cancer.

68Ga-AAZTA-093 is a novel radiotracer incorporating a hypoxia sensitive nitroimidazole(NI)-moiety and a PSMA-targeting. In this study, we observed the safety, biodistribution, radiation dosimetry and diagnostic value of 68Ga-AAZTA-NI-093 PET/CT in patients with prostate cancer.
