Active clinical trials for "Prostatic Neoplasms"

Open label, non-randomised phase II clinical pilot study

The goal of this clinical research study is to learn if adding dovitinib to the combination of abiraterone acetate and prednisone may help to control metastatic CRPC. The safety of this drug combination will also be studied.

The objective of this study is to determine if systemically infused allogeneic bone marrow derived mesenchymal stem cells (MSC) home to sites of prostate cancer in men with localized adenocarcinoma of the prostate that are planning to undergo a prostatectomy. Investigators plan to systemically infuse MSCs 4, 6 or 8 days prior to enrolled subjects' planned prostatectomies. Investigators will then quantify the relative amount of donor MSC DNA to recipient DNA present in patients' explanted prostate specimens. This will be accomplished via BEAMing digital PCR. This trial will provide the foundation for future studies aimed at engineering MSCs to deliver a toxin to sites of metastatic prostate cancer.

This randomized pilot phase I trial studies the side effects of dietary fat levels and abiraterone acetate uptake in patients with metastatic hormone-resistant prostate cancer. Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Eating a low or high fat diet may increase the uptake of abiraterone acetate.

The management of (castration-resistant) prostate cancer (CRPC) is becoming increasingly complex. The use of peripheral anti-androgens with gonadorelin analogues (maximum androgen blockade) is common place. Following the failure of such an approach, several strategies may be employed. Both corticosteroids and estrogens have a role and increasingly chemotherapy is being used. The demonstration of enhanced survival using 3 weekly docetaxel has meant that this is viewed by many as the standard of care for fit patients. Melphalan is an established alkylating drug that has demonstrated some activity in CRPC, but to date, myelosuppression has prevented adequate dosing. We have recently conducted a phase I dose escalation study using melphalan and whole blood stem cell re-infusion and it shows that median overall survival is 22 months, which is higher than the median survival rate of 19 months for Docetaxel Data from a previous phase I study has proved the successful administration of higher doses of IV Melphalan in combination with autologous blood infusion in patients with Castration-resistant prostate cancer. Rapid falls in circulating tumour cells were seen within 2 weeks of starting Melphalan, however slow platelet recovery meant longer periods of platelet transfusion. For this study we intend to assess the efficacy of an intensified intravenous melphalan with autologous whole blood stem cell transplantation over three treatment cycles. 39 patients will be enrolled over a 3 year period and at least 17 patients need to survive progression free at least 6-months for this study to be considered positive. Mel-CAP is a combination chemotherapy consisting of two chemotherapy drugs: MELPHALAN and LENOGRASTIM for 3 cycles alternately.

Radiation therapy is a well-established treatment modality for clinically localized prostate cancer. Men who choose to undergo radiation treatments for prostate cancer will have to live with the side effects for many years. Attempts have been made to protect surrounding tissues while delivering high dosage of radiation to cancer. With the rectum being so close to the prostate, many patients still suffer from side effects caused by radiation injury to the rectum, especially those who received conventional external beam radiotherapy. CyberKnife is an FDA approved radiosurgical devise. Its flexible robotic arm allows radiation beams to be delivered in different directions, providing a highly conformal, uniform dose with steep dose gradients. Therefore, treatment with the CyberKnife radiosurgical system should minimize the toxicity to the surrounding structures. CyberKnife System also incorporates a dynamic tracking system to allow the robot to correct the targeting of therapeutic beams during treatment. These improvements allow for dose escalation within the prostate with less normal tissue toxicity. The purpose of this study is to estimate the proportion of patients with endoscopically detectable telangiectasia as the indication of radiation injury to the rectum, after CyberKnife Treatment for prostate cancer.

The purpose of this study is to evaluate the incidence of urinary and rectal acute side effects of a pelvic and prostatic intensity-modulated arctherapy with simultaneous integrated boost (SIB-IMRT)combined with long-term androgen deprivation for patients with high risk localized prostate cancer

This clinical trial studies stereotactic body radiation therapy in treating patients with low- and intermediate-risk prostate cancer. 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 confirm that tasquinimod used as maintenance therapy is active and tolerable in patients with metastatic castrate-resistant prostate cancer not progressing after a first chemotherapy with docetaxel.

The purpose of this study is to assess whether NaF PET/CT scans can be used to evaluate treatment response in bone metastases in subjects with prostate cancer treated with the investigational drug, TAK-700.
