Filter by:The study is a non-randomized, prospective trial of men scheduled for radical prostatectomy for treatment of prostate cancer as standard of care and will undergo a series of pre-operative multi-modality imaging studies. Pre-operative imaging will be correlated with actual pathology results and statistical modeling performed to determine the most informative imaging biomarkers in predicting cancer location and aggressiveness (Gleason Score).
This phase II trial studies the impact of 68GA-PSMA-11 positron emission tomography (PET)/computed tomography (CT) scan on treatment strategies for patients with prostate cancer. Diagnostic imaging procedures, such as 68GA-PSMA-11 PET/CT scan, may help doctors plan the best treatment for prostate cancer.
Men diagnosed with significant cancer confined to the prostate currently undergo radical therapy directed to the whole prostate (radiotherapy or prostatectomy). These provide good cancer control but can cause significant side effects. Focal Therapy involves targeting the cancer alone, whilst leaving healthy prostate gland alone. Case series have shown similar cancer control over 5 years with a much better side effect profile. However, there have been no randomised control trials (RCTs) comparing the success in cancer control and the quality of life in patients that undergo radical therapy vs those that undergo focal therapy. Further, there is a need to assess the use of additional therapies that may improve the cancer control outcomes following focal therapy. By having a trials platform with two RCTs (CHRONOS-A and CHRONOS-B) that reflect best patient and physician preferences/ equipoise, the investigators aim to answer these questions. To improve acceptability, recruitment and compliance, the investigators have an embedded study aimed at reviewing clinician and patient perspectives and trial acceptability. CHRONOS-A will compare radical therapy to focal therapy, whilst CHRONOS-B will compare focal therapy alone to focal therapy with various therapies targeting the testosterone pathway that can shrink the cancer before it is treated. The investigators think this might improve outcomes further for men that definitely want focal therapy.
The hypo-FLAME 2.0 study is a multicenter phase II study (n=124) investigating the feasibility and safety of a reduction in the overall treatment time of radiotherapy for prostate cancer patients, making use of hypofractionated stereotactic body radiotherapy with focal boosting. We are looking for the optimal overall treatment time for this treatment strategy in the Hypo-FLAME 2.0 trial. In this study the total treatment time will be halved (15 days) in comparison with the total treatment time in the former hypo-FLAME trial (29 days) (NCT02853110).
This phase II trial studies the side effects and best dose of niraparib, and to see how well it works in combination with standard of care radiation therapy and hormonal therapy (androgen deprivation therapy) in treating patients with prostate cancer that has a high chance of coming back (high risk). Niraparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Adding niraparib to the usual treatments of radiation therapy and hormonal therapy may lower the chance of prostate cancer growing or returning.
The present study aims to optimize the use of systemic therapy relative to local tumor ablation in a prospective randomized clinical trial and to validate the existence and characterize the clinical and pathology phenotype of oligometastatic (OM) prostate cancer (OM-PCa). For local tumor ablation we propose to use the novel non-invasive and highly effective technique of Image-Guided Single Dose Radiotherapy (SDRT), which we showed is capable of conferring long-term local relapse-free rates in ≥ 90% of metastatic PCa lesions. Concomitantly, we will develop, validate and implement a diagnostic algorithm for OM-PCa and functionally characterize Prostate Cancer Stem Cells (pCSCs) from human samples to correlate their molecular phenotypes with tumor response to treatment. The long-term aim is to define the indications, standardization of treatment protocols and outcome for OM-PCa. Response assessment will be via local control, metastasis-free survival and overall survival rates. Cases displaying the clinical OM phenotype, as disclosed via long-term disease remission following tumor ablation, will represent the basis to identify the molecular signatures of OM-PCa. These signatures will be used to develop and validate an algorithm to predict the OM phenotype upfront and define the treatment strategy that may lead to cure.
The purpose of this study is to determine if Prostate-Specific Membrane Antigen (PSMA) positron emission tomography (PET) scans used in this study accurate and better at imaging participants' prostate cancer than the usual methods.
This study is a prospective, open label, single arm phase II trial. A total of 22 patients will be treated with atezolizumab, PROSTVAC, and pre-operative MVA-BN-Brachyury to confirm the efficacy of prostatic combination immunotherapy and to measure the relative change in the number of tumor infiltrating CD8+ lymphocytes within the prostate tissue between the paired biopsy and radical prostatectomy specimens.
The purpose of this study is to determine what the safest dose of talazoparib plus temozolomide for participants with metastatic castration resistant prostate cancer. The purpose of Phase II is to test the efficacy (effectiveness) of talazoparib and temozolomide at the maximum tolerated dose, which was determined to be 1mg talazoparib and 75mg/m² temozolomide in the Phase Ib portion of this study.
This phase II trial studies how well erdafitinib in combination with abiraterone acetate or enzalutamide works in treating patients with double negative prostate cancer. Erdafitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Testosterone can cause the growth of prostate cancer cells. Abiraterone acetate lowers the amount of testosterone made by the body. This may help stop the growth of tumor cells that need testosterone to grow. Enzalutamide blocks the use of testosterone by the tumor cells. Giving erdafitinib with abiraterone acetate or enzalutamide may work better in treating patients with prostate cancer compared to abiraterone acetate or enzalutamide alone.
