Filter by:Prostate cancer (PCa) is the most common cancer among men and is even more common in the military and veteran population. For patients with advanced prostate cancer, the most common treatment includes lowering the levels of the hormone testosterone as much as possible. This is called "androgen deprivation therapy" or "ADT". Unfortunately, ADT also causes patients to be fatigued, weak and to loose muscle. This is often referred to as "sarcopenia" and it leads to falls, poor quality of life and higher risk of death. Currently, there is no treatment for sarcopenia because the investigators do not understand the mechanisms that cause it. The mitochondria is the part of the cells responsible for providing energy to muscles but to this date the investigators do not know if it is affected in prostate cancer patients with sarcopenia due to ADT. The overall goal of this proposal is to establish if the mitochondria is responsible for sarcopenia in patients with prostate cancer receiving ADT. The investigators will measure mitochondrial function, muscle mass and strength, and feelings of fatigue and quality of life in patients with prostate cancer before starting and after 6 months of ADT.
Prostate cancer (PCa) is the most frequently diagnosed cancer in Canadian men. While the majority of PCa is slow growing and responds well to first line treatment, a proportion of cases (10%) progress to metastatic form resulting in more than 4 000 deaths annually in Canada and 250 000 worldwide. Currently, first line treatment for PCa includes surgery, radiation and androgen deprivation therapy (ADT). A rapid evolution in the understanding of disease biology, combined with approvals of new therapies including immunotherapy, novel chemotherapy, hormonal agents and a bone calcium matrix-targeted radionuclide, along with further drugs in development, have made treatment decisions for metastatic castration-resistant prostate cancer (mCRPC) increasingly complex and challenging. This is a Phase II Study of Cabazitaxel plus prednisone in patients with metastatic castration-resistant prostate cancer (mCRPC). The current study is designed to determine if cabazitaxel will improve progression free survival (PFS) or overall survival (OS). This study will enroll patients with mCRPC, who have been previously treated and progressed under docetaxel or abiraterone regimen. Patients must meet the study eligibility criteria and must be competent to give informed consent.
Primary Objective: - To determine whether changes in uptake of [18F]DCFPyL PET/CT scans at baseline and after 6 weeks of treatment for metastatic castrate resistant prostate cancer, correlates with radiographic progression free survival (rPFS) as defined by Prostate Cancer Working Group 3 (PCWG3) criteria. Secondary Objectives: - To determine whether changes in uptake of [18F]DCFPyL PET/CT scans correlate with overall survival (OS) - To determine whether baseline SUVmax correlate with rPFS - To compare number of lesions detected with standard imaging at baseline and at the time of progression
Background: Immunotherapy drugs help the body to fight cancer. Scientists think that combining some of these drugs will make them work better than when used alone. This may be true for many types of cancer, including castration-resistant prostate cancer (CRPC). Objective: To test if the combination of the drugs BN-brachyury, M7824, N-803, and Epacadostat is safe and shrinks tumors. Eligibility: People ages 18 and older with CRPC or another metastatic cancer Design: Participants will be screened with: - Medical history - Physical exam - CT or MRI scans - Possible bone imaging - Blood, urine, and heart tests - Possible tumor biopsy Participants will be treated with a 2-, 3- or 4-drug combinations of the following study drugs in 2-week cycles: - Participants will receive M7824 by IV once every 2 weeks. - Participants will receive N-803 by injection once every 2 weeks. They will record any skin changes at the injection site in a diary. - Participants will receive BN-brachyury as 4 injections to different limbs. They will get the first 3 doses 2 weeks apart. Then they will get doses every 4 weeks for 6 months, then every 3 months for 2 years, then every 6 months. - Participants will take Epacadostat orally every 12 hours. They will keep a pill diary. Participants will have physical exams and blood and urine tests at the start of each cycle. They may have scans every 12 weeks. Participants will continue treatment until their disease gets worse or they cannot tolerate the side effects. Participants will have a follow-up visit 4-5 weeks after they stop treatment. They will have a physical exam and blood tests. They may be asked to return for scans every 3 months.
More than 90% of patients with metastatic castration-resistant prostate cancer (mCRPC) no longer responding to androgen deprivation hormonal therapy have evidence of bone metastases. This is a major cause of death, disability, and decreased quality of life. Radium-223 is radiopharmaceutical meaning that the drug is a radioactive compound used for therapeutic purposes. It is given intravenously (through a vein) every 4 weeks for 6 cycles. Research has demonstrated safety and efficacy in mCRPC patients resulting in radium-223 becoming a standard of care option for such patients in addition to chemotherapy and new oral hormonal drugs enzalutamide or abiraterone. Prior research studies using radium-223 have shown improved survival in about 30% of patients. The same studies in combination with data collected from clinical use have also shown that between 20 and 50% of men do not complete the full 6 cycle course of treatment due to side effects or a rise in prostate specific antigen (PSA) requiring the stoppage of radium-223 therapy to start one of the other drug therapies. The purpose of this study is to determine whether an oral drug called dexamethasone (a corticosteroid) given together with radium-223 may control PSA levels and reduce side effects during radium-223 treatment. Corticosteroids are anti-inflammatory medicines prescribed for a broad range of conditions and are widely used in conjunction with chemotherapy treatments for cancer. Prior research studies have shown that dexamethasone reduces PSA levels by lowering the production of androgens (i.e. male hormones) and improves overall tolerance for cancer-fighting drugs and therapies. Up to 24 men being treated with radium-223 at University Health Network will be enrolled into this study. If the study is positive, it might offer an improved quality of life and extended survival.
After failure on docetaxel, which has been the standard first line therapy for patients with metastatic castration-resistant prostate cancer (mCRPC), several treatment options are currently available. In retrospective studies, resistance has been described to two of the treatment options, enzalutamide and abiraterone, when a splice variant of the Androgen Receptor (AR-V7) is present on circulating tumor cells (CTCs). The investigators hypothesize that patients with AR-V7 positive CTCs do have a meaningful response to cabazitaxel.
Prospective research of Natural Killer cells as predictive biomarkers to stratify patients likely to have longer response time to castration.
To determine if supervised high intensity aerobic and resistance training increases overall survival compared to self-directed exercise in patients with metastatic prostate cancer.
The aim of the trial is to test the hypothesis that the benefit of denosumab is maintained if administered only every 12 weeks as compared to every 4 weeks.
This is a multi-center phase III study to compare the clinical benefit of androgen deprivation therapy with or without docetaxel with or without local radiotherapy with or without abiraterone acetate and prednisone in patient with metastatic hormone-naïve prostate cancer.
