Filter by:This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational combination of drugs to learn whether they work in treating a specific cancer. "Investigational" means that the combination of drugs is still being studied and that research doctors are trying to find out more about it, such as the safest dose to use and the side effects they may cause. It also means that the FDA has not yet approved the combination. The two drugs being tested in this study are tivozanib and enzalutamide. Enzalutamide has been approved by the FDA for treatment of prostate cancer. On the other hand, tivozanib is still investigational, and has not been tested in a combination with enzalutamide before. Enzalutamide is an androgen receptor antagonist (it blocks the activity of the male sex hormones). Prostate cancers are initially dependent on the male hormone testosterone for growth. Hormonal therapies that lower testosterone or block the ability of testosterone to act at the level of the prostate cancer are currently among the most effective treatments for prostate cancers taht have spread to other body organs (metastasized). The effectiveness of hormonal treatments, however, is not permanent, and over time many prostate cancers progress in spite of these treatments. Enzalutamide is a drug that has been proven to help delay the progression of advanced prostate cancer on average for about 8 months. Tivozanib is an anti-angiogenesis medicine that fights different types of cancer by blocking the blood supply to the tumor, so that the tumor does not receive the nutrients it needs to grow. The main goal of this study is to determine whether the combination of tivozanib and enzalutamide is more effective in delaying the progression of disease than when enzalutamide is given alone. This study will also determine whether treatment with the combination of the tivozanib and enzalutamide will have more side effects then treatment with enzalutamide alone.
This study will look at how feasible it is to use a certain type of Computed Tomography (CT) to scan prostate cancer, called a high quality volume CT scan. It is hoped that this technique will help doctors provide a higher-quality image of the prostate cancer, making it easier to plan the area that will be treated. Using this type of CT scan will also lessen the amount of time patients spend in the scanner. This study will not offer patients a different treatment for their prostate cancer. Patients will receive the most appropriate standard treatment whether or not they are in this study.
The aim of this study is to confirm the Efficacy,the Safety and the Quality of Life after TOOKAD® Soluble VTP in localized prostate cancer patients.
Background: - Enzalutamide is a well tolerated hormone therapy that is used to treat advanced prostate cancer. It is given to help kill cancer cells and limit cancer cell growth. A new possible way of treating prostate cancer is using a therapeutic cancer vaccine (immune stimulating therapy) that may help activate the immune system against the cancer. The immune stimulating vaccine will help white blood cells recognize and kill the cancer cells throughout the body. This vaccine therapy has been tested in hundreds of patients and is very well tolerated. Researchers want to see whether this vaccine, given with enzalutamide, is more effective at treating advanced prostate cancer than enzalutamide alone. Objectives: - To compare the safety and effectiveness of enzalutamide with and without vaccine therapy for advanced prostate cancer. Key Eligibility: - Men at least 18 years of age who have advanced castration sensitive prostate cancer. - Patients must have testosterone within the normal range - No evidence of metastatic prostate cancer on computed tomography (CT) or Bone scan - No history of autoimmune diseases - No previous immunotherapy within 3 years Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies will be used to monitor the cancer before treatment. - Participants will be separated into two groups. One group will have enzalutamide and the study vaccine. The other group will have enzalutamide alone. - All participants will take enzalutamide once a day. They will take the drug for 3 months. This form of intermittent therapy is common in this population of patients. - The vaccine group of participants will receive the new study vaccine. They will have a single injection on the first day of the first study cycle. There will be regular booster injections afterward. There will be one injection during the third week of treatment, and one in the fifth week. The vaccine will then be given every 4 weeks until 21 weeks have passed. - Treatment will be monitored with frequent blood tests and imaging studies.
Radiation therapy is one of the standard treatments for men with prostate cancer who have detectable levels of prostate specific antigen (PSA, a prostate cancer specific marker) after surgery. When radiation therapy is given to patients who have an increase in PSA after surgery, it is called "salvage radiation therapy". Currently the standard radiation therapy course length for this type of cancer is around 7 ½ -8 weeks. Sometimes, radiation therapy after prostate removal causes unpleasant side effects. A shorter course of radiation therapy, known as a "hypofractionated" course, gives fewer but higher doses of radiation than standard radiation. The purpose of this study is to test the safety of a shorter course of radiation therapy at progressively lower dose levels and shorter lengths of treatment (hypofractionated) with patients who have had their prostate removed. The study will assess whether the hypofractionated course works better without causing additional side effects to the remaining cancer cells in the prostate bed.
The purpose of the study is to determine the safety and clinical benefit of the combinations of abiraterone acetate and prednisone or abiraterone and dexamethasone in prostate cancer patients. Prednisone will be given at one of three different dose schedules. Dexamethasone will be given at one dose schedule. This will include looking at what side effects occur and how often they occur. In addition the impact of the study drug on quality of life and pain will be evaluated. The study will also collect data on subsequent treatment of patients after they come off the study drug (approximately 4.5 years after the start of study treatment of the first subject participating in the study). By analyzing blood samples, the study aims to identify if some markers could help to understand if the treatment with abiraterone is effective and also help to understand if patients can become resistant.
Background: - Prostate cancer is the most common cancer type among men. Some prostate cancers respond to hormonal therapy. However, some cell characteristics of other prostate cancers cause it not to respond as well to these therapies. Researchers want to see if gadoxetate, a contrast agent used to help identify damaged liver tissue, can help tell these types of prostate cancer apart. It may be able to identify if a man has a type of prostate cancer for which hormone therapy may not work as well. Objectives: - To see if gadoxetate can help identify different types of prostate cancers during imaging studies. Eligibility: - Men at least 18 years of age who have prostate cancer. Participants will be having surgery to either remove the prostate or take tumor tissue samples. Design: - Participants will be screened with a physical exam and medical history. Blood samples will be collected. - Participants will have a magnetic resonance imaging (MRI) scan of the lower torso. They will receive gadoxetate during the MRI scan. - Participants who have surgery will have a sample of their tumor cells collected. Those who have a biopsy will provide cells from this biopsy for study. - Treatment will not be provided as part of this study.
Background: - Enzalutamide is a hormone therapy that is used to treat advanced prostate cancer. It is given after chemotherapy and surgery to help the body destroy the cancer cells. A new possible way of treating prostate cancer is using a vaccine that may help stimulate the immune system. It will help white blood cells recognize and kill the cancer cells in and around the prostate. Researchers want to see whether this vaccine, given with enzalutamide, is more effective at treating advanced prostate cancer than enzalutamide alone. Objectives: - To compare the safety and effectiveness of enzalutamide with and without vaccine therapy for advanced prostate cancer. Eligibility: - Men at least 18 years of age who have advanced castration-resistant prostate cancer. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies will be used to monitor the cancer before treatment. - Participants will be separated into two groups. One group will have enzalutamide and the study vaccine. The other group will have enzalutamide alone. - All participants will take enzalutamide once a day. They will take the drug during 4-week cycles of treatment. - Treatment will be monitored with frequent blood tests and imaging studies. Participants will continue to take the study drug for as long as the cancer does not grow, and the side effects are not severe. - The vaccine group of participants will also have the new study vaccine. They will have a single injection on the first day of the first study cycle. There will be regular booster injections afterward. There will be one on day 15 of the first cycle, the first day of the second cycle. The vaccine will then be given every 4 weeks for the next four cycles, and then every 12 weeks (every 3 cycles) thereafter. Participants will continue to have the study vaccine for as long as the cancer does not grow, and the side effects are not severe.
Prostate cancer has been the most common cancer in men in Finland over the last ten years. Prostate-specific antigen (PSA) plays an important role in screening of prostate cancer. However, PSA has a limited sensitivity and specificity for prostate cancer detection. Commonly, the diagnosis of prostate cancer is done by transrectal ultrasonography (TRUS) guided biopsy. Due to the low accuracy of TRUS, a systematic biopsy is usually performed instead of targeted TRUS biopsy. As biopsy carries a risk of increase in complications, there is an increasing interest in developing more accurate non-invasive imaging modalities. This study will enroll 150 men with clinical suspicion of prostate cancer due to higher serum level of PSA than 2.5 ng/ml and/or abnormal digital rectal examination. Multiparametric magnetic resonance imaging (mpMRI) at 3 Tesla (T) magnetic field using surface coils will be used to non-invasively predict the presence or absence of prostate cancer. Targeted TRUS guided biopsy based on MRI findings will be performed in addition to routine twelve core TRUS biopsy. Moreover, selected serum and urine biomarkers as well as biomarkers extracted from fresh biopsy sample will be collected and correlated with the presence or absence of prostate cancer.
This study aims to see if metformin can delay the time to progression in men with low risk prostate cancer when compared to a placebo.
