Active clinical trials for "Prostatic Neoplasms"

The purpose of this research is to determine if using human placental membrane (also called an allograft) helps to improve recovery time for erectile function and bladder control after having robot-assisted radical prostatectomy (RARP) surgery.

This study is a prospective, open label, single arm phase II trial. A total of 22 patients will be treated with atezolizumab, PROSTVAC, and pre-operative MVA-BN-Brachyury to confirm the efficacy of prostatic combination immunotherapy and to measure the relative change in the number of tumor infiltrating CD8+ lymphocytes within the prostate tissue between the paired biopsy and radical prostatectomy specimens.

This pilot study will investigate the use of PSMA-PET/MRI (Positron Emission Tomography/ Magnetic Resonance Imaging)to guide radiation treatment planning in patients with known or suspected locally metastatic prostate cancer at the time of diagnosis. Patients will undergo a single PSMA-PET/MRI (or PET/CT (Computed Tomography) in some circumstances) prior to initiation of treatment. Following development of a PSMA-PET guided radiation treatment plan, therapeutic radiation will be delivered per standard-of-care parameters and assessments of feasibility and tolerability will be performed.

This study evaluates the diagnostic performance and safety of F-18-PSMA-1007 and F-18-Fluorocholine PET/CT imaging in patients with suspected recurrence of prostate cancer after previous definitive treatment.

Whether a quantitative detection specfic magnetic resonance imaging (MRI) protocol improves prostate cancer (PCa) detection in biopsy naïve men is not adequately studied.

This phase II trial studies how well focal radiation therapy with stereotactic body radiation therapy (SBRT) or high-dose rate (HDR) brachytherapy works in treating patients with low or intermediate-risk prostate cancer. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. HDR brachytherapy uses high doses of radiation to target these tumor cells. Giving focal radiation therapy with SBRT or HDR brachytherapy may target dominant tumor cells while sparing the reminder of the prostate or surrounding normal organs and ultimately reduce side effects while maintaining disease control.

This phase I trial studies the impact of monosodium glutamate (MSG) on 68GA-PSMA-11 PET/CT in decreasing the salivary glands uptake in patients with prostate cancer. Prostate specific membrane antigen (PSMA) is a molecule that is overexpressed by the prostate cancer cells. 68GA-PSMA-11 is an imaging radioactive drug that can target this molecule in tissues for imaging and therapy of prostate cancer. Food substances, such as monosodium glutamate, may reduce salivary gland uptake of 68GA-PSMA-11. Ultimately, giving MSG may reduce potential harm and injury to the salivary glands in patients with prostate cancer treated with PSMA-targeted molecular radiotherapy.

This research is studying two experimental drugs, abemaciclib and atezolizumab, alone and in combination with each other, to learn about the safety and effectiveness of these treatments and their side effects. This is an investigational study treatment for adult men with metastatic castrate resistant prostate cancer (mCRPC) who have progressive disease despite previous treatment with androgen deprivation therapy (ADT). One group of men (men without a genetic mutation called "CDK12 loss") will receive abemaciclib therapy alone. Two other groups of men (men with CDK12 loss in one group and men without CDK12 loss in the other) will receive the combination of abemaciclib and atezolizumab. Another group of men with CDK12 loss will receive atezolizumab therapy alone.

Prostate cancer is the most frequent cancer in men. Today serum prostate specific antigen (PSA) level and digital rectal examination (DRE) are routinely used for screening of prostate cancer. In the case of higher PSA levels and/or abnormal DRE, 10-12 core standard transrectal prostate biopsy (STRUS-B) is preferred method.Most of the pathological T1 stage tumours are diagnosed by this method. But as the prostate volume increases, cancer detection rate of STRUS-B decreases.In the last decade multiparametric prostate magnetic resonance imaging (mpMR) has gained importance in the diagnosis of prostate cancer beside the staging. Now it is possible to biopsies from lesions which are suspicious for cancer in mpMR. Recent studies have shown that mpMR guided prostate biopsies either transrectally or perineally have better cancer detection rates comparing STRUS-B, especially in patients with history of negative previous biopsy. But its use in biopsy naive settings is not recommended.In this study it is aimed to compare cancer detection rate of MR guided MR-US fusion transrectal prostate biopsy with STRUS-B.

The present study is a phase II, open label, single-center, non-randomized, single-dose study. Twenty subjects in total will be enrolled at Weill Cornell Medical College (WCMC)/ NYPH. The primary objective is to evaluate the ability of 89Zr-Df-IAB2M to detect localized, clinically significant (defined as: ≥ 0.5 cm3 with Gleason pattern ≥ 4) prostate cancer (PCa). After the screening period (up to 28 days), each subject will be scheduled to receive 10 mg infusion of IAB2M conjugated with 2.5 mCi 89Zr-Df. 2 - 4 days post-infusion, subjects will undergo a 89Zr-Df-IAB2M PET/CT scan. Images read by a Nuc Med MD reporting: location, SUV and, if possible, size of all areas with abnormal uptake. (they will also undergo a pelvic MRI if they have not obtained an MR image during the screening period or on day of infusion) Optional but recommended 68Ga-PSMA-HBED-CC (5±2mCi) injection and PET/CT scan (1 to 3 hours after the injection) will also be performed prior to radical prostatectomy depending on subject's availability and compliance. Patient will undergo radical prostatectomy after completion of above imaging procedures.
