Active clinical trials for "Prostatic Neoplasms"

Prostate cancer is a leading cause of cancer death among men in the Western world. Early detection of prostate cancer has been shown to decrease mortality, but has limitations with low specificity leading to unnecessary biopsies and over-diagnosis of low-risk cancers. The STHLM3 trial has paved the way for improved specificity in early detection of prostate cancer using the blood-based STHLM3 test for identifying men at increased risk of harbouring significant prostate cancer. Targeted prostate biopsies based on MRI images have been shown to increase sensitivity of high-grade cancers compared to the currently used systematic biopsies, but existing evidence are contradictory and not free from methodological flaws. The primary aim of STHLM3-MR/Fusion is to increase the specificity in early detection of prostate cancer without decreasing the sensitivity of aggressive prostate cancers by introducing targeted prostate biopsies and comparing to traditional prostate biopsies. The primary endpoints are the number of performed biopsies and the number of detected high-grade prostate cancers defined as Gleason 7 or higher. Secondary endpoints include the number of low risk prostate cancers diagnosed and the proportion of patients with up-or downgraded disease after assessment of prostatectomy specimen. Additional aims include to assess the health economic consequences of implementing MRI based prostate cancer diagnostics and to improve the quality and effectiveness of prostate cancer diagnosis in the routine health care in Stockholm. The STHLM3-MR/Fusion project will be performed in two separate phases, analyzed separately. Based on power calculations, approximately 500 planned for prostate biopsies will be included in the first phase. Men who have previously been diagnosed with prostate cancer may not take part in the study. The study period of Phase 1 is March 2016 to January 2017. The second phase will start in autumn 2016 and end by December 2017.

This study is open to men who have biochemical recurrence (BCR, increased PSA) following local treatment of their prostate cancer. Androgen deprivation therapy (ADT) is a standard treatment option, but is only effective for 16-24 months and has a number of side effects that impact quality of life. These side effects may include fatigue, hot flushing, loss of sex drive, brain fog, decreased bone mineral density, loss of muscle mass, mild anemia (low levels of red blood cells that can make people feel tired and weak), diabetes (low blood sugar), heart disease, metabolic syndromes (sometimes called "pre-diabetes" and includes obesity, increased blood pressure, high levels of cholesterol and triglycerides in blood), and risk of fractures. An alternative to continuous ADT is intermittent administration, where patients are given "breaks" from ADT to let their testosterone levels return to baseline. There are a number of potential benefits to intermittent hormone therapy (IHT): (1) longer time to the development of resistance; (2) improved patient quality of life owing to recovery from adverse effects, particularly sexual function; and (3) substantial cost savings owing to less time spent receiving medication. Leuprolide is the name of the ADT / IHT drug. Apalutamide is an investigational drug, which means it has not been approved by the Food and Drug Administration (FDA). It is an antitumor drug, taken by mouth. The purpose of this study is to determine the ability of Apalutamide to extend the time between the first two injections of leuprolide and improve quality of life. This study will also look at the safety of Apalutamide and the effects that Apalutamide has on prostate cancer. Men will be randomized (like flipping a coin) to receive: Group A: Leuprolide + Apalutamide or Group B: Leuprolide only (until second leuprolide injection), then leuprolide + Apalutamide 45 men will be in Group A and 21 men will be in Group B. Leuprolide is given as an intramuscular shot that lasts for 3 months intermittently and Apalutamide is taken by mouth (4 tablets) daily. Each cycle is 4 weeks long. Intermittent treatment with Apalutamide + leuprolide will continue until continuous leuprolide is needed to maintain undetectable PSA levels (i.e., PSA levels rise above undetectable level unless leuprolide is given without pause, every 3 months).

Through this study the investigators seek to build up a repository of prostate ultrasonography videos and prostate MRI scans to enable research into novel anatomical registration techniques. These data will facilitate the development of improved technology that enables targeting of tumours seen on MRI using free-hand biopsy techniques, without the need for a gantry or overlaid perineal grid.

Androgen deprivation therapy (ADT) is widely used as standard therapy in the treatment of locally advanced and metastatic prostate cancer. Hot flushes and night sweats are one of the main side-effects of ADT. There are no successful and well-tolerable treatment options available. A possible treatment for hot flushes is stellate-ganglion block (SGB), used as a means of interrupting parts of the sympathetic nervous system involved in temperature regulation. Objective of this study: To assess the short-term efficacy of stellate ganglion block on hot flush reduction versus sham procedure

This randomized phase II trial studies how well PROSTVAC (prostate-specific antigen [PSA]-TRICOM) works in preventing disease progression in patients with prostate cancer undergoing active surveillance. Vaccines made from a person's tumor cells may help the body build an effective immune response to kill tumor cells that express PSA.

Background: - Prostate cancer is the second leading cause of cancer deaths in American men. A chemical called a radiotracer helps doctors get images of this type of cancer. Researchers want to test a radiotracer called N-[N-[(S)-1,3-dicarboxypropyl]carbamoyl]-4-(18)F-fluorobenzyl-L-cysteine ((18)F-DCFBC) (18F-DCFBC). Objective: - To see if the radiotracer 18F-DCFBC can identify sites of prostate cancer in the body. Eligibility: - Men ages 18 and over with prostate cancer. The cancer must be newly diagnosed, have relapsed, or has spread outside the prostate. Design: Participants will be screened with physical exam and medical history. They will give a blood sample. Participants will be divided into three groups. Group 1: people with cancer only in the prostate scheduled for surgical prostate removal or biopsy at National Institutes of Health (NIH). Group 2: people who had their prostate removed or had radiation therapy and now have a rising prostate-specific antigen (PSA) without other signs of disease. Group 3: people whose cancer has spread to other areas of the body. Participants will have 18F-DCFBC injected into a vein then imaged in a positron emission tomography (PET)/computed tomography (CT) camera. During the scans, they will lie on their back on the scanner table. Group 1 will have a magnetic resonance imaging (MRI) scan. A tube will be placed in the rectum. Coils may be wrapped around the outside of the pelvis. Participants will have a contrast agent injected through an intravenous line. Group 3 will have another PET/CT scan with a different radiotracer, 18F NaF, within 21 days of the 18F-DCFBC scan to look for prostate cancer in the bone. Group 3 will repeat the two PET/CT scans 4-6 months after the initial scans. A few days after each scan, participants will be contacted for follow-up.

STHLM3-MR Phase 2 is a study comparing traditional prostate cancer detection using PSA and systematic biopsies with the improved pipeline for prostate cancer detection using the STHLM3 test and targeted biopsies in a screening context.

To investigate the utility of fluciclovine F 18 for evaluation for metastatic disease in men undergoing laser focal therapy of prostate cancer and the impact on inclusion for a focal therapy cohort.

To evaluate the dosimetry, safety and the detection rate of 68Ga-THP-PSMA PET/CT for identifying the site of prostate cancer metastasis and relapse. It is also to evaluate the association of clinical/pathologic features and 68Ga-THP-PSMA PET/CT detection rate and compare 68Ga-THP-PSMA PET/CT with other imaging procedure.

This phase I trial studies the side effects of anti-PD-1 monoclonal antibody REGN2810 (REGN2810) and/or ipilimumab when given together with stereotactic body radiation therapy before surgery in treating participants with prostate cancer that is growing, spreading, or getting worse, and has spread to other places in the body, or formed a small number of new tumors in one or two other parts of the body. Monoclonal antibodies, such as anti-PD-1 monoclonal antibody REGN2810 and ipilimumab, may interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Giving anti-PD-1 monoclonal antibody REGN2810 and ipilimumab with stereotactic body radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
