Active clinical trials for "Prostatic Neoplasms"

The combination treatment of protein kinase B (AKT) inhibitor, afuresertib, with androgen synthesis enzyme inhibitor, LAE001, may provide an effective treatment for metastatic castration resistant prostate cancer (m-CRPC) patients who have progressed/drug resistant following prior standard care treatments of any anti-androgen. This study intends to identify the most appropriate combined doses of LAE001/prednisone and afuresertib in m-CRPC patients who have progressive disease or are intolerant of 2 prior standard treatments of any anti-androgen or anti-androgen treatment plus chemotherapy.

This phase II trial studies how well giving bicalutamide with or without Akt inhibitor MK2206 works in treating patients with previously treated prostate cancer. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as bicalutamide, may lessen the amount of androgens made by the body. Akt inhibitor MK2206 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether bicalutamide is more effective with or without Akt inhibitor MK2206 in treating prostate cancer.

This is a single-center, open-label, non-randomized Phase I study of weekly Cabazitaxel with concurrent intensity modulated radiation therapy (IMRT) (A type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles.) and androgen deprivation therapy (Treatment to suppress or block the production or action of male hormones) in patients with locally advanced prostate cancer. It is hoped that by adding Cabazitaxel to the standard IMRT, greater local disease control can be achieved and eventually the cure rate can be increased. After this study, the maximally tolerated dose of Cabazitaxel that could be used in combination with radiation can be found. Men with locally advanced high risk prostate cancer represent a group of patients for whom cure is potentially achievable utilizing a multimodality approach. More aggressive treatment upfront with chemotherapy and ADT may improve the long term disease control. We hypothesize that Cabazitaxel may be added to radiation therapy safely, and we anticipate that this novel approach will improve disease control and eventually improve survival for locally advanced prostate cancer patients.

The purpose of this trial is to give a shorter course (5 ½-6 weeks) of proton radiation that has as little side effects on normal bladder and rectal tissues as the usual longer course (8 weeks) of proton radiation, without decreasing the chance of killing prostate cancer cells.

The goal of this clinical research study is to learn about the effect of different combinations of exercise, supportive counseling, and methylphenidate/placebo for the treatment of fatigue in patients with prostate cancer. The safety of this treatment combination will also be studied. Methylphenidate is a stimulant designed to increase the activity of the central nervous system. A placebo is not a drug. It looks like the study drug but is not designed to treat any symptom, disease or illness. It is designed to be compared with a study drug to learn if the study drug has any real effect. The exercise in this study is designed to help improve your physical fitness and energy levels. Supportive counseling is designed to help to control symptoms, fatigue, anxiety, depression, pain, and/or sleep disorders.

This will be a Phase II study evaluating the effectiveness and toxicity of a specific radiation therapy regimen. This choice of daily dose is based on the prior published experience showing safety and efficacy of hypofractionated regimens. The total dose is calculated to be effective for late effects which has been shown to be effective and safe in a large prospective Phase II study. If the hypothesis for the prostate is is true, then this regimen should be at least as effective or more effective for tumor control than the current conventional therapy.

This purpose of this study is designed to compare two types of images; magnetic resonance imaging (MRI) and Trans-Rectal Ultrasound (TRUS) to see which one performs more accurately for the image-guided insertion of Fiducial Markers(FMs) within the tumour. Though effective for guiding FM placement at the poles of the prostate gland due to excellent visualization of the prostatic boundaries, TRUS may not be ideally suited for marking the GTV. Conventional TRUS is neither sufficiently sensitive nor specific for accurate visualization of intra-prostatic tumor. A new interventional MRI technique enables needle guidance to the gross tumour Volume (GTV) for FM placement. It is of particular importance that both techniques be evaluated to enable which one is more effective so that it can be implemented in the designs of future trials involving dose-escalation to prostate.

RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells and shrink tumors. Androgens can cause the growth of prostate cancer cells. Androgen-deprivation therapy may lessen the amount of androgens made by the body. It is not yet known whether radiation therapy is more effective with or without androgen-deprivation therapy in treating patients with prostate cancer. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with radiation therapy given together with androgen-deprivation therapy in treating patients with prostate cancer.

Radical prostatectomy (RP) is the most common curative approach offered to men with newly diagnosed prostate cancer. Unfortunately, up to half of these patients will have factors placing them at high risk of their cancer recurring. Having radiotherapy after RP is known to improve cure rates, but what is not known is whether it should be given straight after the operation or only when there is a rising PSA after surgery indicating active cancer. Immediate RT may not benefit all men, and can cause serious side effects such as bladder and bowel problems and impotence. International lack of consensus on the optimal timing of RT has resulted in varied clinical practice. This phase 3 trial will compare the two approaches.

RATIONALE: Androgens can cause the growth of prostate cancer cells. Androgen ablation therapy may stop the adrenal glands from making androgens. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether androgen-ablation therapy is more effective with or without docetaxel in treating metastatic prostate cancer. PURPOSE: This randomized phase III trial is studying androgen-ablation therapy and chemotherapy to see how well they work compared to androgen-ablation therapy alone in treating patients with metastatic prostate cancer.
