Active clinical trials for "Prostatic Neoplasms"

Prostate cancer is the most common non-skin cancer diagnosed among men and the second leading cause of male cancer deaths in the United States. In 2013, it is estimated that 29,270 men have died from prostate cancer. Although radiation and surgery are quite effective for localized disease, there is no effective cure for men who present with metastatic prostate cancer as the 5-year relative survival rate is only 28%. Currently, androgen deprivation therapy (ADT) via medical or surgical castration is the standard first-line therapy in men with metastatic disease but castration-recurrent prostate cancer (CRPC) eventually emerges with a median time of 18-24 months. Once CRPC develops, secondary hormonal manipulation, chemotherapy, and immunotherapy are marginally effective. Given the dismal prognosis of metastatic prostate cancer, new ideas and novel approaches must be explored to improve the clinical outcome. In this regard, recently emerging data suggest that local tumor control may enhance the effectiveness of subsequent systemic therapies. Therefore, in this proposal, the investigators have designed a Phase I/II study in which they will prospectively evaluate the safety and feasibility of cytoreductive prostatectomy in men with newly diagnosed mPCa.

This purpose of this study is to evaluate the safety and effectiveness of a technique called focal high-dose-rate (HDR) brachytherapy as treatment for prostate cancer that has come back in the prostate after prior radiotherapy. The study will examine the safety and efficacy of the treatment. The type of radiation that participants in this research will receive is targeted directly at the areas of the prostate where recurrent disease is evident, while avoiding treatment of the normal appearing prostate. This involves the placement of a radioactive material in the affected area of the prostate temporarily, where it remains for a short period of time, and then is subsequently removed using a minimally invasive technique called HDR Brachytherapy.

This trial examines the feasibility and toxicity of focal brachytherapy in patients with low-risk prostate cancer.

The study is an open-label Phase 1 study of the combination of relacorilant with enzalutamide in patients with metastatic castration resistant prostate cancer (mCRPC).

This research study is comparing the use of a new form of hormonal therapy used with radiation as a possible treatment for intermediate risk prostate cancer. More specifically, this research would help determine whether this new form of hormonal therapy is as effective as the standard hormone therapy while also preserving erectile function.

The purpose of this study is to determine what the safest dose of talazoparib plus temozolomide for participants with metastatic castration resistant prostate cancer. The purpose of Phase II is to test the efficacy (effectiveness) of talazoparib and temozolomide at the maximum tolerated dose, which was determined to be 1mg talazoparib and 75mg/m² temozolomide in the Phase Ib portion of this study.

This phase II trial studies how well niraparib, when given before surgery, works in treating patients with high risk prostate cancer that has not spread to other parts of the body (localized) and alterations in deoxyribonucleic acid (DNA) repair pathways. Niraparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

A significant proportion of patients with localized prostate cancer, and treated for curative intent by radiotherapy, have a local recurrence. Among these patients with local recurrence, few receive curative remedial treatment but most of them are treated with palliative hormonal therapy without any chance of long-term recovery. The use of Focused Ultrasound (HIFU) in focal treatment (only on recurrence) is an effective and not very morbid option, especially compared to surgery. The quality of this treatment is conditioned by both an early diagnosis of recurrence, a precise localization of recurrence in the prostate and a rigorous extension assessment for the detection of occult metastases. Innovations in medical imaging have led to the development of a new generation of "hybrid" machines that combine PET (Positron Emission Tomodensitometry) and MRI (Magnetic Resonance Imaging) technology. Associated with the use of 68Gallium-labeled PSMA (Prostate-Specific Membrane Antigen), a new tracer specific for prostate cancer, the investigators believe that this PET-MRI imaging technique can: To identify at an early stage the metastatic patients and to allow a more adapted therapeutic management. A better evaluation of the limits of local recurrence and therefore a more precise definition than with MRI alone of the tumor zone to be destroyed. Finally, the investigators believe that the PET-MRI / 68Ga-PSMA exam, used for the selection of patients eligible for focal HIFU treatment and used for the treatment itself, should allow obtaining an optimal control of the cancer recurrence with the least possible side effects.

The main purpose of this study is to determine the safety, tolerability (how your body reacts to the drug) and effectiveness of REGN5678 with or without cemiplimab. There are additional purposes of this study including measurement of the levels of REGN5678 in your blood when given alone and when given in combination with cemiplimab, and collection of any evidence of tumor shrinkage. The study has 2 parts. The goal of Part 1 is to determine a safe dose(s) of REGN5678 when it is given alone and then followed by combination with cemiplimab. The goal of Part 2 of the study is to use the REGN5678 drug dose(s) found in Part 1 to see how well REGN5678 alone or in combination with cemiplimab works to shrink tumors. Note: All the above primary, secondary objectives will apply to each cohort (unless specified) in the study including those who receive sarilumab and those who do not receive sarilumab.

The purpose of this randomized trial is to investigate the efficacy and toxicity of percutaneous high-dose radiotherapy in patients with oligometastases of hormone refractory prostate cancer. The effectiveness will be tested in comparison to an observation group, in which no further therapy is initially given. Treatment can be stereotactically hypofractionated or conventionally fractionated.
