Active clinical trials for "Prostatic Neoplasms"

The goal of this research is to examine the ability of Gallium-68 (68Ga) Prostate-Specific Membrane Antigen-11 (PSMA-11) positron emission tomography/computed tomography (PET/CT) to detect sites of recurrent prostate cancer in patients with biochemical recurrence previously treated with radical prostatectomy (RP) or external beam radiation (EBRT) and to assess treatment response to subsequent salvage therapy.

This is a single site, prospective, Phase 1 pilot trial intended to evaluate the safety and tolerability of adding one IV dose of Desmopressin to CRPC subjects at least 30 minutes prior to commencing standard IV Docetaxel treatment7,8.

The purpose of this study is to evaluate safety and short-term oncological efficacy of the NanoKnife Irreversible Electroporation System for localised prostate cancer. Irreversible electroporation (IRE) is the method of focal treatment for prostate cancer, which is already proven by FDA as method of the surgical ablation of soft tissue. It has not received clearance for the therapy or treatment of any specific disease or condition.

The present study aims to optimize the use of systemic therapy relative to local tumor ablation in a prospective randomized clinical trial and to validate the existence and characterize the clinical and pathology phenotype of oligometastatic (OM) prostate cancer (OM-PCa). For local tumor ablation we propose to use the novel non-invasive and highly effective technique of Image-Guided Single Dose Radiotherapy (SDRT), which we showed is capable of conferring long-term local relapse-free rates in ≥ 90% of metastatic PCa lesions. Concomitantly, we will develop, validate and implement a diagnostic algorithm for OM-PCa and functionally characterize Prostate Cancer Stem Cells (pCSCs) from human samples to correlate their molecular phenotypes with tumor response to treatment. The long-term aim is to define the indications, standardization of treatment protocols and outcome for OM-PCa. Response assessment will be via local control, metastasis-free survival and overall survival rates. Cases displaying the clinical OM phenotype, as disclosed via long-term disease remission following tumor ablation, will represent the basis to identify the molecular signatures of OM-PCa. These signatures will be used to develop and validate an algorithm to predict the OM phenotype upfront and define the treatment strategy that may lead to cure.

Androgen deprivation therapy (ADT) is considered standard of care for prostate cancer. However, changes in the patients metabolism are usually seen as a result of hormone therapy. These changes include increased fat mass, decreased lean mass, weight gain, high blood cholesterol, increased incidence of diabetes, and possibly increased incidence of cardiac events such as heart attack. The researchers of this trial would like to learn if these change in body mass are affected by the presence of brown fat in the body. Brown fat is made up of fat cells that are stored in the body and generate heat to control body temperature. Levels of brown fat are at the highest in newborn babies and decrease over time into adulthood. The researchers of this trial would like to learn more about these changes in metabolism during prostate cancer treatment by studying the changes in brown fat during the first 12 months of hormone therapy.

Given the activity of docetaxel in patients with progressive, metastatic castration-resistant prostate cancer, this study is being undertaken to evaluate the activity of tesetaxel, an orally bioavailable taxane, in chemotherapy-naive and chemotherapy-exposed patients.

The purpose of this study is to determine the safety and efficacy of a short course of radiotherapy (40Gy/5 fractions/29 days) for the treatment of high risk prostate cancer currently being managed with primary androgen deprivation therapy (PADT).

This is a multi-center, open-label study of 2 doses of leuprolide acetate 17 mg depot, administered three months apart, in subjects with prostate cancer who might benefit from medical androgen deprivation therapy

RATIONALE: Diagnostic procedures, such as MRI, may help measure oxygen levels in tumor cells. It may also help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This clinical trial is studying how well MRI works in assessing hypoxia in patients with localized prostate cancer undergoing stereotactic body radiation therapy.

While radiation therapy with androgen ablation (hormone reduction) is the standard method of treating locally advanced prostate cancer. New treatments are being combined with radiation therapy in an effort to further improve the cure rates. This study proposes to combine an experimental drug, TNFerade™ Biologic, (also called AdGVEGR.TNF.11D or "TNFerade") at different dose (amounts) levels in combination with radiation. TNFerade™ Biologic is a form of gene transfer therapy that when injected into the tumor has shown to increase the effect of radiation therapy.
