Active clinical trials for "Prostatic Neoplasms"

This is a randomized study aiming to assess the feasibility of a phase II randomized controlled trial of different high-intensity training interventions and usual care (UC) in men with prostate cancer (PCa) undergoing active surveillance (AS).

ACE is a multi-centre proof of concept Phase I/II trial of the CXCR2 antagonist AZD5069, administered in combination with enzalutamide, in patients with metastatic castration resistant prostate cancer(mCRPC). The investigators will be investigating the safety and toxicity of the combination.

This is a psychosocial/behavioral study and does not involve administration of any treatment or diagnostic procedures. We will use a randomized trial to test the hypothesis that a decision analysis model that provides individualized estimates of quality-adjusted disease-free survival for each of the treatment options for clinically localized prostate cancer will lead to higher quality treatment decisions congruent with a patient's values leading to improved decisional regret and treatment satisfaction. In this trial, all patients would be evaluated at baseline for their utilities for various clinically important health states. The control arm will receive counseling regarding treatment options using standard patient-physician interactions and nomogram-predicted probabilities of treatment outcome for the various treatment options and they will be unaware of the decision analysis recommendation. The treatment arm would be counseled using standard patient-physician interactions and they would also be provided with a personalized treatment recommendations based on the decision analysis model prior to treatment selection. The primary endpoint of this study will be regret-free survival at 2 years after treatment. There will be a 1:1 randomization. A random permuted design will be used to assure approximate balanced number of patients in the two groups over time.

Prostate cancer (PC) represents one of the most common cancers in industrialized countries. Patients with localized disease may be treated with surgery or radiation, while androgen ablation is used as first-line therapy in patients with metastatic disease. While most patients initially respond well to this hormonal therapy, they most ultimately become unresponsive and recur within 2 years as androgen-independent prostate cancer (AIPC). Recently, docetaxel-based regimens have demonstrated improved survival in men with AIPC in two different, large, phase III studies. However, the median overall survival was prolonged for only 2 or 3 months. Androgen independent (AI) progression involves variable combinations of clonal selection, adaptive up-regulation of anti-apoptotic genes, ligand-independent androgen receptor (AR) activation, alternative growth factor pathways, and immune system escape. Additional therapeutic strategies targeting molecular mechanisms mediating resistance, combined with immunotherapy must be developed. One strategy to improve therapies in advanced PC involves targeting genes that are activated by androgen withdrawal, either to delay or prevent the emergence of the resistant AI phenotype. Recently, a scientist,identified Heat Shock Protein (Hsp27) as a highly over-expressed gene in AIPC. Hsp27 knockdown using antisens oligonucleotides (ASO) and small interfering RNA (siRNA) increased apoptotic rates and enhanced hormone- and chemo-therapy in PC. She developed and patented a 2nd generation ASO targeting Hsp27 that has been licensed (investigational drug called OGX-427) and clinical trials phase I/II is currently in process in PC. Despite OGX-427 efficiency, the functional role of stress induced Hsp27 in castration or chemotherapy-induced apoptosis remains undefined. The purpose of this study is to elucidate the pathways leading to Hsp27 action in androgen-independent prostate cancer in order to 1/ Increase the pharmacological safety of OGX-427 and 2/find new specific therapeutic targets and treatment strategy for androgen-independent prostate cancer .

The purpose of this study is to investigate the effect of the study medication (Eligard®) on cancer markers (in the blood) of prostate cancer.

RATIONALE: Receiving standard information and watching a video or DVD at home that describes treatment options and treatment outcomes may help patients decide to receive treatment in a clinical trial. PURPOSE: This randomized clinical trial is studying implant radiation therapy to see how well it works compared with surgery in treating patients with prostate cancer.

Patients with hormone and docetaxel refractory prostate cancer or relapsed/refractory non-Hodgkin's lymphoma for which no available standard therapy or therapy which may provide clinical benefit is available will be enrolled. Primary objectives: estimate the maximum tolerated dose and dose-limiting toxicities. Secondary objectives: Response rate, pharmacokinetic and pharmacodynamic profiles, Prostate Specific Antigen response and renal elimination.

The purpose of this study is to determine whether or not Aranesp® (Darbepoetin Alfa), administered every fourth week, is effective in the treatment of blood shortage (anemia) compared to standard care of treatment (blood transfusions) in patients with anemia due to hormone refractory prostate cancer.

RATIONALE: Zoledronate may prevent bone loss associated with long term androgen deprivation therapy. It is not yet known whether zoledronate combined with calcium is more effective than calcium alone in preventing bone loss. PURPOSE: Randomized phase III trial to compare the effectiveness of zoledronate combined with calcium with that of calcium alone in preventing bone loss in patients with stage III or stage IV prostate cancer who have received long-term androgen deprivation therapy.

Prostate cancer is a major public health problem and there is a strong need of new preventive strategies based on drug and lifestyle interventions. It is now well-established that healthy eating patterns and increasing physical activity can prevent or delay prostate cancer progression. Intake of cruciferous vegetables (e.g. broccoli, cabbage, cauliflower, Brussels sprouts, kale) has been associated with decreased risk of prostate cancer progression; however the underlying biological mechanisms remain unknown. The investigators propose to undertake a pilot study on a group of men with early prostate cancer on active surveillance to determine whether a diet rich in broccoli will induce changes in tumor size and blood flow measured by conventional Magnetic Resonance Imaging (MRI) techniques. Men with early prostate cancer on active surveillance who have visible cancer lesions on MRI will be recruited onto this double-blinded randomized intervention and they will be asked to eat one portion of broccoli soup per week for 6 months. The investigators will test two varieties of broccoli (standard and 'Beneforte extra' broccoli) that are able to deliver two different levels of sulforaphane (SF), an active compound extensively studied for its potential anticancer properties. This study will involve MRI scans, blood and urine collection before and after a 6 month intervention period. This study design will not only allow us to observe diet-induced changes within the prostate but also at the systemic level. In addition, participant's lifestyle (habitual diet and physical activity) will be assessed by food diaries and exercise questionnaires. This study has been funded by Biotechnology and Biological Sciences Research Council (BBSRC) and Prostate Cancer foundation (PCF).
