Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to determine if apalutamide plus gonadotropin releasing hormone (GnRH) agonist in participants with high-risk, localized or locally advanced prostate cancer receiving primary radiation therapy results in an improvement of metastasis-free survival.

RATIONALE: Eating a diet high in soy foods may lower the risk of some types of cancer. Isoflavones are compounds found in soy food that may prevent cancer. PURPOSE: This randomized phase II trial is studying how well soy isoflavones work in treating patients with recurrent prostate cancer or rising prostate-specific antigen

This randomized phase IIA trial studies how well antiandrogen therapy works with or without axitinib before surgery in treating patients with previously untreated prostate cancer that is known or suspected to have spread to lymph nodes. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as antiandrogen therapy may lessen the amount of androgen made by the body. Axitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known if antiandrogen therapy is more effective with or without axitinib before surgery in treating patients with prostate cancer.

The goal of this clinical research study is to learn if a prostate implant (brachytherapy) can help to control intermediate risk prostate cancer. The safety of this procedure will also be studied. Prostate brachytherapy is performed by inserting permanent seeds (which are radioactive pellets) into your prostate in order to treat the prostate cancer with radiation therapy.

The purpose of this study was to evaluate the efficacy of enzalutamide plus androgen deprivation therapy (ADT) as measured by radiographic progression-free survival (rPFS) based on central review. The study also evaluated the safety of enzalutamide plus ADT in mHSPC.

This phase I trial studies the side effects and best dose of stereotactic body radiation therapy in treating patients with prostate cancer after undergoing surgery. Stereotactic body radiation therapy may be able to send x-rays directly to the tumor and cause less damage to normal tissue.

The purpose of this study is to compare toxicities between 2 external beam radiation fractionation schemes plus a brachytherapy boost for prostate cancer. Our current standard use a 2 Gy per fraction schedule which is compare to the experimental hypofractionated 3 Gy per day approach with neo adjuvant hormonal therapy. It will demonstrate the feasibility and safety of such a treatment regimen in prostate cancer. It may also set base for a larger randomized trial.

This randomized phase III trial studies enzalutamide to see how well it works compared to enzalutamide, abiraterone, and prednisone in treating patients with castration-resistant metastatic prostate cancer. Androgens can cause the growth of prostate cancer cells. Drugs, such as enzalutamide, abiraterone acetate, and prednisone, may lessen the amount of androgens made by the body.

The purpose of this study is to evaluate the feasibility and short-term safety and effectiveness of the NanoKnife System when used to ablate localized prostate cancer in intermediate risk subjects with organ-confined prostate cancer. This study will evaluate the feasibility of the NanoKnife System as a focal therapy.

This study is comparing the safety and effectiveness of abiraterone acetate alone, followed by the addition of prednisone (when the participant's disease worsens or the physician feels it would lessen symptoms of toxicity) versus the current approved treatment regimen which involves the concomitant use of prednisone in conjunction with abiraterone acetate. Additionally, this study is also examining why participants stop responding to treatment with abiraterone acetate by evaluating blood and tissue.
