Active clinical trials for "Prostatic Neoplasms"

20 patients with invasive castration resistant prostate cancer and radiologically verified metastases will be enrolled into the Phase I Clinical Trial. The trial is a dendritic cell based immunotherapy. Autologous dendritic cells will be obtained by leukapheresis and elutriation and stimulation by cytokines. The induced dendritic cells will have to pass viability, immunophenotyping and sterility criteria and will be injected into a cryoablated region of the primary prostate cancer tumor. The treatment is supplemented by immunomodulatory regimens.

The goal of this clinical study is to determine the efficacy and safety of Seviteronel, a lyase-selective inhibitor of CYP17 and an androgen receptor antagonist, in patients with castration-resistant prostate cancer (CRPC) who have been previously treated with enzalutamide and/or abiraterone.

This is a pilot clinical study of hyperpolarized pyruvate (13C) injection that includes the acquisition of magnetic resonance (MR) data and will be performed in men with localized prostate cancer. Part 1: Five patients will be evaluated for reproducibility of 13C HP MR imaging measurements obtained 2-3 weeks apart with no interim treatment. Part 2: Five patients will be evaluated for the change in 13C HP MR imaging measurements after 2 months of ADT. 13C HP MR data will be acquired in two parts of the study (which can occur simultaneously): Part 1: Patients will undergo imaging at baseline and will be repeated two to three weeks later (with no intervention in the interim) to evaluate reproducibility. Part 2: Patients will undergo imaging at baseline, initiate androgen deprivation therapy, and undergo repeat imaging two months after initiation of ADT to evaluate the ability of the imaging to reflect a metabolic response to treatment. The change in pyruvate/lactate ratio and lactate levels will be measured and compared to baseline at these timepoints.

The main purpose of study is to compare the effectiveness of Hypofractionated IMRT boost Radiotherapy to Conventional IMRT boost Radiotherapy for high-risk prostate cancer patients combined with Androgen Deprivation Therapy.

Prostate cancer is the most common non-skin tumor diagnosed in men and the second leading cause of cancer death in men in Western countries. Between 10-20% of patients are diagnosed at metastatic stage and about half of those diagnosed in early stages will develop metastases. After the clinical benefit of mitoxantrone and the improved survival of 2-3 months provided by docetaxel in first line, the second search is driven to look for effective second lines treatments. In recent years, there are new drugs for the treatment of prostate cancer, revolutionizing the therapeutic sequence and survival. Thus, androgen deprivation therapy, treatment of choice, induces an improvement of symptoms in approximately 70-80% of patients, but it is limited by the development of mechanisms of resistance to androgen deficiency. Docetaxel was the first chemotherapy drug to increase survival in patients with metastatic prostate cancer. The second cytotoxic drug approved in the second line treatment of metastatic CRPC has been cabazitaxel. Enzalutamide improves survival in patients with metastatic CRPC who had progressed to chemotherapy and also in patients who had not received chemotherapy. To date, there are no biomarkers available that allow us to identify which patients from a clinical or molecular view are those that will be able to benefit from the treatment options currently available. The presence of the TMPRSS2-ETS rearrangement has been shown to correlate with efficacy in clinical practice abiraterone. There is scientific and preclinical background that makes one suspect that the molecular alteration may influence the same way enzalutamide antiandrogen activity, but it has not been determined to date. The objective of this study is to determine whether the efficacy and safety of enzalutamide, when administered to patients with castration resistant prostate cancer prior to administration of docetaxel is influenced by the presence or absence of the fusion gene TMPRSS2- ETS.

This is a prospective single center trial to examine the rate of negative biopsy result and quality of life after focal ablation by radiofrequency energy. The primary evaluation involves assessing the rate of negative biopsy result using MR-US fusion biopsy six months after focal ablation of the prostate. Urinary and sexual quality of life will be assessed through validated measures. The hypothesis of our study is that focal ablative therapy will result in a greater likelihood of negative biopsy on followup biopsy than that observed in men who elect not to undergo therapy.

Background: Some people who have been treated for prostate cancer still have high prostate-specific antigen (PSA) levels. This may indicate cancer. These people have non-metastatic castration sensitive prostate cancer (nmCSPC) or biochemical recurrent prostate cancer. Researchers think the immune system can be taught to fight and kill cancer cells. They think an immunotherapy vaccine called prostvac could help reduce PSA levels in people with this type of prostate cancer. Objective: To test if prostvac can decrease tumor growth rate as measured by PSA compared to getting surveillance alone. Eligibility: Men ages 18 or older who have nmCSPC or biochemical recurrent prostate cancer Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Bone scan Computed tomography (CT) scan, or magnetic resonance imaging (MRI) and positron emission tomography (PET) scan: They lie in a machine that takes pictures of the body. Electrocardiogram: Soft electrodes are stuck to the skin to record heart signals. Participants will be part of 1 of 2 arms: Arm A will get prostvac for 6 months. Arm B will have surveillance for 6 months followed by prostvac for 6 months. During the prostvac period, participants will get prostvac as a shot under the skin on weeks 1, 3, and 5, and then monthly for a total of 5 months. Participants will have follow-up visits at least every month until they recover from prostvac side effects or their cancer worsens. Visits may include repeats of screening tests. Participants will be followed for up to 15 years. They will have a physical exam every year for the first 5 years. They will have phone calls once a year.

30-40% of patients who undergo radical prostatetecomy (RP) with curative intent for their localized prostate cancer experience relapse of their disease. Thus, improved therapeutic approaches are needed in this patient population. Enhancing the patient's anti-tumor immune response prior to surgery may improve long-term outcomes following RP

This pilot trial studies how well nanoparticle albumin-bound rapamycin works in treating patients with cancer that as has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced cancer) and that has an abnormality in a protein called mechanistic target of rapamycin (mTOR). Patients with this mutation are identified by genetic testing. Patients then receive nanoparticle albumin-bound rapamycin, which may stop the growth of cancer cells by blocking the mTOR enzyme, which is needed for cell growth and multiplication. Using treatments that target a patient's specific mutation may be a more effective treatment than the standard of care treatment.

Current standard treatment for prostate cancer involves giving patients approximately 40 doses of radiotherapy, one dose per day over an 8 week period. The purpose of this study is to assess the effects of giving two separate high doses of a special type of precision radiotherapy to the prostate and then 5 weeks (instead of 8 weeks) of standard radiotherapy. Hypothesis: It is safe to give patients an extra two doses of high-precision radiotherapy prior to commencing a shorter period of standard radiotherapy for prostate cancer.
