Filter by:The aim of this study is: - To investigate which sexual side effects occur after external beam radiation therapy and brachie therapy - To investigate how many patients are affected - To investigate if there is a time dependency for the severity of the sexual side effects - To investigate if there is a dose dependency for the severity of the sexual side effects - To find predicting and associated factors for the discovered sexual side effects to help identifying patients at risk
This study will develop a first-in-man CTC-based molecular taxonomy of CRPC in the context of novel AR-directed therapies, categorize different patterns of resistance in this disease setting, and describe their evolution over time and treatment.
This study is comparing the effectiveness of enzalutamide with or without abiraterone acetate for men with high-risk, localized prostate cancer.
The main purpose of this study is to learn more about how the investigational drug, LY3022855, affects the immune system in participants with advanced breast or prostate cancer that has not responded to other treatments. Treatment may last up to 6 cycles (cycle = 6 weeks).
The purpose of this study is to evaluate the outcomes of patients treated with an high dose radiation regimen using either stereotactic hypofractionated or normofractionated radiotherapy for oligometastatic prostate cancer and to establish efficacy (producing a desired result or effect) and safety in this setting.
The study will be conducted in 2 Stages. The primary objective of Stage 1 of the study is to identify the maximum tolerated dose (MTD) of ES414 administered intravenously to patients with mCRPC. Secondary objectives are to evaluate the tolerability, pharmacokinetics (PK), pharmacodynamics (PD), immunogenicity, cytokine response, and clinical activity of ES414. The primary objective of Stage 2 of the study is to evaluate the clinical activity of ES414 in patients that have or have not received prior chemotherapy. Secondary objectives are to further characterize the safety profile, PK, PD, and immunogenicity of ES414.
This Phase 3 study will target approximately 100 men over age 18 who have a biochemical relapse or other evidence of relapse of prostate cancer after primary treatment. The purpose of this study is to: A. Provide expanded access the drug 11C-choline. B. Determine the performance characteristics (sensitivity, specificity, positive predictive value, negative predictive value) of 11C-choline PET/Computed Tomography (CT) and PET/Magnetic Resonance Imaging (MRI) in the detection of metastatic prostate cancer in patients with biochemical relapse of prostate cancer after primary treatment in a prospective manner. C. Determine the optimal Prostate-Specific Antigen (PSA) trigger value in 11C-choline PET/CT and PET/MRI positive patients through a prospective study. D. Determine factors that predict a confirmed positive 11C-choline PET/CT and PET/MRI using a multivariable analysis of clinical and pathologic data collected prospectively. E. Compare the individual performance characteristics of 11C-choline PET/CT and 11C-choline PET/MRI and the combination of 11C-choline PET/CT and PET/MRI Study Protocol: 1. Patients entered into the study will undergo a 11C-choline PET CT scan and MRI scan. 2. The CT and MRI images will be evaluated for evidence of metastatic prostate cancer. 3. The 11C-choline PET CT and MRI images will be evaluated for evidence of metastatic prostate cancer. 4. Evidence of metastasis on conventional imaging or 11C-choline PET will be confirmed with biopsy or surgical pathology when possible, or by response to treatment on subsequent imaging. 5. Rates of confirmed metastasis between conventional CT and MRI images will be compared with the 11C-choline PET CT and MRI images. 6. Upon conclusion of each imaging protocol, the referring physician will receive written documentation of the results. At this time, the patient will be considered off study and no further follow up is required.
There is no randomized controlled trial (RCT) comparing Conformal Radiotherapy (3DCRT) versus the Intensity Modulated Radiotherapy (IMRT) in terms of toxicity and disease control. Data from retrospective studies show that IMRT reduces the risk of severe late complications. More recently, the results from the RTOG 0126 study have also confirmed the benefit from IMRT in reducing acute toxicity for prostate cancer treated with conventional dose escalation. Therefore, to investigate the real clinical benefit of the IMRT over 3DCRT using a hypofractionated schedule in prostate cancer, the investigators developed a RCT.
This study will examine the effect of supervised exercise training on cardiopulmonary function in men receiving the combination of enzalutamide (ENZ) and androgen deprivation therapy (ADT) for treatment of non-metastatic, hormone-naïve prostate cancer. No study to date has examined the efficacy, tolerability, and safety of exercise training to prevent and/or mitigate common adverse toxicities in men receiving combination androgen suppression therapy for hormone-naïve prostate cancer.
The purpose of this study is to evaluate the effectiveness of a weight management program for men undergoing a prostatectomy by seeing if the program is easy to follow, impacts weight gain, and reduces risk of cancer recurrence in the participants.
