4 Clinical Trials for Various Conditions
This trial studies how well nutrition and exercise interventions work in reducing androgen deprivation therapy-induced obese frailty in prostate cancer survivors. Individualized nutrition and exercise advice for prostate cancer patients on androgen deprivation therapy may help to reduce obese frailty and change the levels of myokines in blood.
This phase II trial studies how well hyperpolarized carbon C 13 pyruvate magnetic resonance spectroscopic imaging works in predicting treatment response in patients with prostate cancer. Hyperpolarized carbon C 13 pyruvate magnetic resonance spectroscopic imaging may help to accurately predict how prostate cancer patients will respond to standard therapy (abiraterone and apalutamide).
Background: - Few studies or literature are available about the long-term safety of repeated peptide vaccinations in people over a period of time. Long-term vaccination may be needed to control tumors. Researchers gave a group of men a series of vaccine injections over 2 years. Now they want to give those same men the new version of the vaccine. They want to see if it produces different types of immune responses and also ensure that repeated vaccinations are safe. Objectives: - To find out the long-term safety of repeated T-cell receptor alternate reading frame protein (TARP) peptide vaccinations. Eligibility: - Men who took part in National Cancer Institute (NCI) protocol 09-C-0139. Design: * Participants will be screened with blood tests, scans, physical exam, medical history, and an evaluation of how well they perform everyday activities. * Participants will have apheresis. Blood will be removed with a needle from one arm. A machine will separate the white blood cells. The blood, minus the white cells, will be returned through a needle in the other arm. * Participants will have 14 visits. At each visit, they will have a physical exam and blood tests. They will discuss any side effects. * Participants will get vaccine injections at weeks 3, 6, 9, 12, 15, and 24. The vaccine will be made from the participants own cells. * Participants will get a Vaccine Report Card to complete after receiving vaccine. * The study lasts 96 weeks.
RATIONALE: New diagnostic procedures, such as C-11 choline PET-CT scan, may be effective in finding cancer that has spread to the bone and lymph nodes in patients with prostate cancer. PURPOSE: This clinical trial is studying how well C-11 choline PET-CT scan works in finding metastases in patients with newly diagnosed high-risk prostate cancer.
