NCT07516223
The study aims to determine if a less painful and less invasive prostate biopsy approach is safe for certain men with a high risk of prostate cancer. Currently, when a man has a suspicious MRI scan, standard medical guidelines recommend a "combined biopsy." This means the urologist performs a Targeted Biopsy (taking 3-5 tissue samples directly from the suspicious area seen on the MRI) followed immediately by a Systematic Biopsy (taking 12 additional samples blindly from the rest of the prostate). While this combined approach maximizes cancer detection, the 12 extra needles from the systematic biopsy increase the risk of bleeding, pain, and urinary infection. Researchers believe that for men who already have a very high prostate-specific antigen (PSA) level and a highly suspicious MRI, the targeted biopsy alone might be enough to detect any dangerous cancer. In these high-risk men, the extra 12 systematic needles might offer little to no additional benefit ("diminishing returns"). In this study, 850 men will undergo the standard combined biopsy procedure. However, to test the researchers' theory with extreme precision, the tissue samples from the Targeted Biopsy and the Systematic Biopsy will be placed into completely separate, uniquely barcoded jars (the "One Core, One Jar" spatial mapping protocol). The pathologist will examine each tissue sample independently, without knowing which method was used to collect it. By comparing the results within each patient, the study will determine exactly how many dangerous cancers were found exclusively by the systematic biopsy. If this number is clinically negligible (less than 5%) in men with high PSA levels, it will prove that the 12 extra needles are unnecessary for this specific group. The ultimate goal of the trial is to safely "de-escalate" prostate cancer diagnostics-sparing high-risk men from the physical trauma, complications, and costs of unnecessary systematic sampling, while ensuring no dangerous cancers are missed.
NCT03503344
This phase II trial studies the how well apalutamide with or without stereotactic body radiation therapy work in treating participants with castration-resistant prostate cancer. Testosterone can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. It is not yet known whether giving apalutamide with or without stereotactic body radiation therapy works better in treating participants with castration-resistant cancer.
NCT02312557
This phase II trial studies how well pembrolizumab works in treating patients with prostate cancer that has spread to other places in the body and keeps growing even when the amount of testosterone in the body is reduced to very low levels despite previous treatment with enzalutamide. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells.
NCT04519879
This phase II trial studies how well white button mushroom supplement works in reducing prostate-specific antigen (PSA) levels in patients with prostate cancer that has come back (recurrent) or has favorable risk and has not undergone any therapy (therapy naive). PSA is a blood marker of prostate growth. White button mushroom supplement may affect PSA level, various parameters of immune system and levels of hormones that may have a role in prostate cancer growth.
NCT03442556
This phase II trial studies how well docetaxel with carboplatin followed by rucaparib camsylate works in treating patients with metastatic castration resistant prostate cancer (spread outside of prostate and resistant to testosterone suppression) with homologous recombination DNA repair deficiency. Chemotherapy drugs, such as docetaxel and carboplatin, work to stop the growth of cancer cells, by stopping them from dividing or spreading. Rucaparib camsylate may stop the growth of tumor cells with defects in the ability to repair mistakes in DNA by forcing additional errors so that the cancer cells cannot overcome the number of errors and will then die. Giving induction docetaxel and carboplatin followed by maintenance rucaparib camsylate may work better in treating patients with castration resistant prostate cancer.
NCT03406858
This phase II trial studies how well pembrolizumab and HER2Bi-armed activated T cells work in treating patients with castration resistant prostate cancer that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. HER2Bi-armed activated T cells are made using T cells and may target and kill cancer cells. Giving pembrolizumab and HER2Bi-armed activated T cells may work better in treating patients with castration resistant prostate cancer.
NCT03709550
This phase I/II trial studies the side effects and best dose of decitabine and how well it works when given together with enzalutamide in treating patients with castration resistant prostate cancer that has spread to other places in the body. Androgen can cause the growth of prostate cancer cells. Drugs, such as enzalutamide, may lessen the amount of androgen made by the body. Decitabine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving decitabine and enzalutamide may work better in treating participants with castration resistant prostate cancer.
NCT03501940
This study provides fluorine F 18 DCFPyL positron emission tomography/computed tomography (PET/CT) to participants with prostate cancer that has come back. Diagnostic procedures, such as fluorine F 18 DCFPyL PET/CT, may help find and diagnose prostate cancer and find out how far the disease has spread.
NCT02215161
This phase II trial studies selinexor in treating patients with prostate cancer that has spread to other parts of the body (metastatic), keeps growing even when the amount of testosterone in the body is reduced to very low levels (castration-resistant), and did not respond to treatment (refractory) with abiraterone acetate and/or enzalutamide. Selinexor may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
