Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to evaluate the safety of combining Actinium- J591 with radiation therapy or with androgen deprivation therapy.

Prostate cancer is the most common malignancy amongst men in United States. Androgen deprivation therapy (ADT) with long acting gonadotropin releasing hormone agonists is routinely used as adjuvant therapy in intermediate and high risk localized or locally advanced prostate cancer. Since ADT induces insulin resistance and diabetes, it is important that cellular and molecular effects of ADT are investigated to define precisely the mechanisms involved in the pathogenesis of insulin resistance. Pioglitazone, a known insulin sensitizer, may provide amelioration of insulin resistance in these patients.

The aim of this study is to determine the safety and tolerability of 64Cu-SARbisPSMA in participants with untreated, confirmed Prostate Cancer.

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.

Current standard prostate biopsy techniques, used to definitively diagnose prostate cancer (PC), utilises an ultrasound guided biopsy approach, that offers unsatisfactory specificity and sensitivity for clinical significant PC. This often leads to harmful unnecessary biopsies. To improve the overall detection of clinical significant PC, multiparametric magnetic resonance imaging (mpMRI) has emerged as a new technique that might be useful in selecting the appropriate patient for biopsy. Nevertheless, mpMRI fail to detect cancer in some circumstances and the exact role of mpMRI is undetermined. Currently, the majority of PC is diagnosed either incidentally or by unsystematic screening with prostate specific antigen (PSA). PSA suffers from being an organ specific, but cancer unspecific serum biomarker. PSA testing may neither rule out or confirm the presence of prostate cancer. Newer biomarkers have shown promise in curbing some of this sensitivity and specificity gap, but still needs refinement. In the present study, the investigators will use mpMRI and a new set of urine and plasma biomarkers in combination, prior to performing standard biopsies in order to develop a prediction model for the biopsy outcome. If proven successful the model would offer excellent risk stratification and possibly mitigating the need for biopsies.

This phase I/II trial studies the side effects and best dose of decitabine and how well it works when given together with enzalutamide in treating patients with castration resistant prostate cancer that has spread to other places in the body. Androgen can cause the growth of prostate cancer cells. Drugs, such as enzalutamide, may lessen the amount of androgen made by the body. Decitabine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving decitabine and enzalutamide may work better in treating participants with castration resistant prostate cancer.

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.

This phase II trial studies how well internal radiation therapy works in treating patients with low-risk prostate cancer. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells.

This randomized pilot phase I trial will evaluate if quercetin enhances the uptake of green tea polyphenols in the prostate tissue of men taking green tea extract and undergoing radical prostatectomy. Side effects of green tea extract and quercetin in combination with green tea extract will also be evaluated. In preclinical studies, green tea polyphenols have anticancer and cancer preventative effects in a number of malignancies. Likewise, in preclinical studies quercetin was found to enhance the anticancer effects of green tea. This trial is designed to translate these findings forward in a short-term human intervention trial.

The purpose of this study is to compare, in patients with prostate or breast cancer, the accuracy of 18F-NaF PET imaging to 99mTc whole body bone scans with single-photon emission computed tomography (SPECT).
