Active clinical trials for "Prostatic Neoplasms"

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.

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" and "MVA") 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 is a first-in-human study to evaluate the safety and immunogenicity of ChAdOx1.5T4-MVA.5T4 vaccination regime. It is evaluated in neo-adjuvant setting in low and intermediate risk localised prostate cancer patients who have either decided to have their prostate removed or are stable on active surveillance.

This pilot clinical trial studies combined fluorine F 18 sodium fluoride (NaF)/ fludeoxyglucose F 18 (FDG) positron emission tomography (PET) and magnetic resonance imaging (MRI) in measuring response to a drug, radium Ra 223 dichloride (Ra-223), in treating patients with prostate cancer that has not responded to hormone therapy and has spread to other parts of the body. Combining NaF/FDG in a simultaneous PET/MRI scan may help doctors accurately measure how well patients respond to treatment with radium Ra 223 dichloride.

A single-arm, open-label Phase II clinical trial to evaluate the effect of G-202 on the perfusion and volume of the prostate using non-invasive multiparametric prostate magnetic resonance imaging (mpMRI).

Open-label, dose rising, Phase IIa trial of intratumorally-injected NanoPac® 6, 10, or 15 mg/mL in subjects with prostate cancer scheduled for prostatectomy.

This phase Ib trial studies the side effects and best dose of niraparib when given together with radium Ra223 dichloride in treating subjects with prostate cancer that keeps growing even when the amount of testosterone in the body is reduced to very low levels and has spread from the primary site to the bone. Radium Ra 223 dichloride, acts like calcium to target cancer in the bones and may deliver radiation directly to the bone tumors, limiting damage to the surrounding normal tissue. Niraparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving radium Ra 223 dichloride and niraparib may work better in treating subjects with hormone-resistant prostate cancer metastatic to the bone.

The purpose of this study is to determine a safe, effective, and tolerable dose of PRX302 for the treatment of low to intermediate risk prostate cancer.

This was a placebo-controlled, double-blind, randomized trial designed with the aim of establishing whether curcumin influenced the duration of treatment interruption and rate of prostatic specific antigen(PSA) progression, compared with placebo among men with prostate cancer receiving intermittent androgen deprivation therapy.

The purpose of this study is to determine if trans-rectal microwave ablation of the index tumor of patients with low-risk prostate cancer is sufficiently precise and safe, using MRI-transrectal ultrasound image registration.

This is a prospective imaging study evaluating the utility of baseline metabolic MR imaging with Hyperpolarized Pyruvate (HP) (13C) as a predictive response biomarker to androgen signaling inhibition in patients with castration-resistant prostate cancer.
