Filter by:In this observational study researchers want to gather more information about safety and survival in patients suffering from castration-resistant prostate cancer (CRPC) which has spread to the bone and were treated with radium-223 in routine clinical practice in Taiwan. Radium-223 (Ra-223) is an alpha particle-emitting radioactive agent approved for the treatment of men with metastatic castration-resistant prostate cancer (mCRPC).
The aim is to define the postponement of next line systemic treatment (NEST), by the use of metastasis-directed therapy in patients with oligoprogressive castration-refractory prostate cancer. This will be defined by the NEST-free survival. Furthermore the investigators will use 18F PSMA PET-CT as investigational imaging, to assess the predictive value and impact on treatment policy.
The aim of this trial is to evaluate SHR3680 combined with SHR3162 and SHR3680 single drug to improve Metastatic Castration Resistant Prostate Cancer Patients whether the patient's overall survival (OS) is superior to placebo.
This trial will evaluate the use of one versus two DNA vaccines, delivered concurrently with PD-1 blockade using pembrolizumab followed by treatment with pembrolizumab alone, and delivered over a prolonged period of time (for a maximum of 2 years (32 cycles) or until radiographic progression) on the treatment of castrate-resistant, metastatic prostate cancer. The hypothesis to be tested is that delivering two vaccines with PD-1 blockade will elicit a greater frequency and magnitude of tumor-directed CD8+ T cells, and thereby increase the percentage of patients experiencing objective anti-tumor effect as measured by PSA declines and/or objective radiographic responses. Participants must be 18 years of age or older and can expect to be on treatment for 2 years (32 cycles) and on study for up to 4 years (including 2 years of follow up via phone).
The purpose of this phase II, single-arm, open-label, three center study is to evaluate the efficacy, safety, and tolerability of sEphB4-HSA in patients with mCRPC (metastatic castration-resistant prostate cancer). The study drug, sEphB4-HAS, is a form of protein that has not been approved for sale by the United States Food and Drug Administration (FDA). The study drug prevents tumor cells from multiplying and blocks several compounds that promote the growth of blood vessels that bring nutrients to the tumor.
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 is a multicenter, randomized, controlled, phase 2 clinical trial designed to evaluate the safety and efficacy of I-131-1095 radiotherapy in combination with enzalutamide compared to enzalutamide alone in participants with prostate-specific membrane antigen (PSMA)-avid metastatic castration resistant prostate cancer (mCRPC) who have progressed on abiraterone. Participants must be chemotherapy-naive and must be ineligible or refuse to receive taxane-based chemotherapy at time of study entry. PSMA-avidity will be determined by central imaging review based on assessment of 18F-DCFPyL PET/CT imaging during screening. Eligible participants meeting the PSMA-avidity criteria will be randomized in a 2:1 ratio to receive either I-131-1095 in combination with enzalutamide (80 participants) or enzalutamide alone (40 participants). An interim analysis for efficacy will be performed after a minimum of 48 evaluable participants have PSA data for at least three months following the first dose of randomized treatment. All participants will be followed for efficacy, safety assessments, survival status, adverse events of special interest, and new anti-cancer therapy for at least one year or to the end of the study (whichever is later) following the first dose of randomized treatment. Safety data will be monitored by an independent Data Monitoring Committee and the sponsor.
This phase I trial studies side effects and best dose of PSCA-chimeric antigen receptor (CAR) T cells in treating patients with prostate stem cell antigen positive (PSCA+) castration resistant prostate cancer that has spread to other places in the body (metastatic). PSCA-CAR T cells are immune cells that have been engineered in the laboratory to kill tumor cells. This is done by using a virus to insert a piece of deoxyribonucleic acid (DNA) into the immune cells that allows them to recognize prostate tumor cells. It is not yet known how well PSCA-CAR T cells works in killing tumor cells in patients with metastatic castration resistant prostate cancer.
This study is a multinational Phase 3, randomized, double-blind, non-inferiority, efficacy and safety study of oral HC-1119 (80 mg/day) versus enzalutamide (160 mg/day) in asymptomatic or mildly symptomatic patients with progressive metastatic castration-resistant prostate cancer (mCRPC). The following assessment of prostate cancer status will be collected during the course of the trial: soft tissue disease on computed tomography (CT) scan or on magnetic resonance imaging (MRI), bone disease on radionuclide bone scans, FACT-P and EQ-5D, Brief Fatigue Inventory, and PSA. Throughout the study, safety and tolerability will be assessed by the recording of adverse events, monitoring of vital signs and physical examinations, safety laboratory evaluations, and 12-lead electrocardiograms (ECGs). Blood samples for population pharmacokinetics for HC-1119 and enzalutamide and related metabolites will be collected.
This is a clinical trial of a new treatment for prostate cancer that is a type of vaccine that could be a new way to treat cancer. A vaccine that could alert the immune system to the presence of cancer cells in the body may enable the immune system to target and kill those cells effectively. This vaccine is intended to work by making the immune system kill cells that have a special protein (called 5T4) that is present on the surface of cancer cells. The vaccine is made up of two recombinant viruses ("ChAdOx1"- chimpanzee adenovirus Ox1 and "MVA" - modified vaccinia Ankara) that have been designed to produce the 5T4 protein and have been modified so that they are weakened and cannot reproduce themselves within the body like normal viruses. Once injected into the body, these viruses make the 5T4 protein and help the body's immune system to learn to target this protein and destroy cancer cells. This vaccine will be used in combination with the immunotherapy drug called nivolumab which is an anti-PD-1 (Programmed Death protein-1) monoclonal antibody. This is a molecule that releases the brakes on the immune system and helps the immune system to kill cancer cells more efficiently. Nivolumab as a monotherapy was approved for treatment of several tumour types but not for the prostate cancer. This study will evaluate the safety and efficacy of ChAdOx1-MVA 5T4 vaccine in combination with nivolumab in low and intermediate risk prostate cancer patients who have elected to have their prostate removed and in patients with advanced metastatic prostate cancer.
