Moderately Hypofractionated Radiotherapy for Prostate Cancer.
Prostatic NeoplasmsGenital NeoplasmsRadiation therapy is one of the standard treatments for men with prostate cancer. Moderately hypofractionated radiotherapy has been established to be equivalent to standard fractionated radiotherapy in several large randomized clinical trials, however different hypofractionated regimens have been used in these studies. The two most common hypofractionated regimens are 70 Gy in 28 fractions and 60 Gy in 20 fractions, both are considered standard of care, however it is not unknown which regimen is better in terms of effectiveness and toxicity. The aim of this randomized controlled clinical trial is to compare the two hypofractionated radiotherapy regimens using Helical Tomotherapy.
Hyperpolarized Pyruvate (13C) MR Imaging in Monitoring Patients With Prostate Cancer on Active Surveillance...
Prostate AdenocarcinomaProstate CancerThis phase II trial studies the side how well hyperpolarized carbon C 13 pyruvate (HP C-13 pyruvate) magnetic resonance imaging (MRI) works in monitoring patients with prostate cancer on active surveillance who have not received treatment. Diagnostic procedures, such as MRI, may help visualize HP C-13 pyruvate uptake and breakdown in tumor cells.
PSMA-PET Registry for Recurrent Prostate Cancer
Recurrent Prostate CancerThis study aims to institute a province-wide registry leveraging the availability of a new Positron Emission Tomography tracer, [18F]-DCFPyL and PET expertise across Ontario centers to improve our ability to characterize patterns of recurrence and personalize therapies in men with recurrent prostate cancer after primary treatment.
Effectiveness of the SpaceOAR Vue System in Subjects With Prostate Cancer Being Treated With Stereotactic...
Prostate CancerTo demonstrate the effectiveness of the SpaceOAR Vue System in reducing late gastrointestinal (GI) toxicity in subjects undergoing Stereotactic Body Radiotherapy (SBRT) to treat prostate cancer.
The Safety and Tolerability of PGV001-based Personalized Multi-peptide Vaccines in the Adjuvant...
Prostate CancerThis proof of concept study is designed to test the safety and tolerability of PGV001-based personalized multi-peptide vaccines in combination with CDX-301 in subjects with a history of aggressive prostate cancer, in the tumor free adjuvant setting.
68Ga-PSMA-11 PET/CT in Patients With Various Types of Cancer
Prostate CancerPositron-Emission TomographyTo evaluate the potential usefulness of 68Ga-PSMA-11 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions, efficacy assessment and recurrence monitoring in various types of cancer.
Testing the Effects of Low Dose Apalutamide on Prostate-Specific Antigen (PSA) Levels in Men Scheduled...
Localized Prostate CarcinomaProstate Adenocarcinoma2 moreApalutamide is an anti-androgen that blocks the effect of testosterone on prostate cancer growth. This phase IIa trial is designed to determine whether very low doses of apalutamide, given for 3 to 4 weeks before prostate surgery to men with prostate cancer confined to the prostate gland, reduces plasma levels of PSA (a biomarker of apalutamide's ability to block testosterone). If low dose apalutamide lowers PSA levels in this setting, further study of this agent in men with localized prostate cancer who wish to delay definitive therapy with surgery or radiation may be warranted.
PSMA Specific [68Ga]-P137 Peptide Probe for PET Imaging in Prostate Cancer
Prostate CancerTo study the radioactive uptake of [68Ga]P137 in the lesion sites of PCa patients and evaluate the ability of [68Ga]P137 to detect PSMA overexpression in PCa patients (especially those with recurrent or advanced PCa).
Diet and Physical Activity Intervention for the Prevention of ADT-Induced Metabolic Changes in Patients...
Localized Prostate CarcinomaProstate AdenocarcinomaThis clinical trial studies the effects of a diet and physical activity intervention on blood measures of lipids and insulin resistance in patients with prostate cancer undergoing radiation therapy (RT) and androgen deprivation therapy (ADT). ADT effectively slows the growth of prostate cancer cells, thereby enhancing the therapeutic effectiveness of RT. Despite the clinical gains, ADT leads to an array of side effects including insulin resistance, abnormal lipid levels, weight gain, increased visceral fat mass coupled with increased muscle wasting, and quality of life deterioration. A diet and physical activity intervention may intercept or prevent the abrupt metabolic and physiologic changes caused by androgen deprivation therapy in prostate cancer patients receiving ADT and RT.
Ferumoxtran-10-enhanced MRI in Prostate Cancer Patients
Prostate CancerMetastasis1 moreThis will be a confirmatory, prospective, open-label, single-arm, reader-blinded, multi-centre phase 3 study to assess the diagnostic accuracy and safety of Ferrotran®-enhanced MRI in comparison to unenhanced MRI in the detection of pelvic lymph node metastases in newly-diagnosed adult patients with prostate cancer and an intermediate to high risk for lymph node metastases, based on the D'Amico criteria.
