NCT00007644
Radical prostatectomy provides potentially curative removal of the cancer. However, it subjects patients to the morbidity and mortality of the surgery and may be neither necessary nor effective. Expectant management does not offer potential cure. However, it provides palliative therapy for symptomatic or metastatic disease progression, avoids potentially excessive and morbid interventions in asymptomatic patients, and emphasizes management approaches for focus on relieving symptoms while minimizing therapeutic complications. The primary objective of this study is to determine which of two strategies is superior for the management of clinically localized CAP: 1) radical prostatectomy with early aggressive intervention for disease persistence or recurrence, 2) expectant management with reservation of therapy for palliative treatment of symptomatic or metastatic disease progression. Outcomes include total mortality, CAP mortality, disease free and progression free survival, morbidity, quality of life, and cost effectiveness.
NCT00488982
This is a two-arm, randomized Phase II study of intermittent chemotherapy with and without GM-CSF. All patients will receive six 21-day cycles of docetaxel 75 mg/m2 on Day 2 of each cycle and 5 mg prednisone twice a day on Days 1-21. Following six cycles of chemotherapy, eligible subjects will be randomized to no maintenance therapy or to maintenance GM-CSF therapy. The GM-CSF group dose schedule will be 250 mcg/m2 subcutaneous (SQ) daily Days 15-28 every 28 days. Patients in both groups will continue until disease progression at which time GM-CSF will be discontinued and chemotherapy will again be administered.
NCT01981109
The primary purpose of this research is to describe patient characteristics predictive of an imaging study positive for distant metastases in patients with castration-resistant prostate cancer and no known distant metastases.
NCT01727154
The purpose of this study is to evaluate the immune response induced by sipuleucel-T (Provenge®).
NCT02501759
This pilot clinical trial studies transrectal magnetic resonance imaging (MRI)-guided biopsy to see how well it works in identifying cancer in patients with suspected prostate cancer who are scheduled to undergo standard biopsy. Transrectal MRI-guided biopsy uses a thin needle inserted through the rectum into the prostate and takes a sample of tissue, guided by MRI. MRI uses magnets to take pictures of the prostate and may be able to identify cancer. Transrectal MRI-guided biopsy may be more accurate and cause patients less pain than standard ultrasound-guided biopsy. It is not yet known whether transrectal MRI-guided biopsy is more effective than ultrasound-guided biopsy in identifying prostate cancer.
NCT01303705
This clinical trial will examine a novel combination of anti-OX40 to induce proliferation of memory and effector T cells in conjunction with cyclophosphamide (CTX) and radiation to induce tumor antigen release with the overall goal of promoting an immune response against prostate cancer.
NCT01188408
LE-DT is a novel, proprietary delivery system of docetaxel developed by NeoPharm, Inc. Docetaxel (currently marketed as Taxotere) is an anti-microtubular network agent and is one of the most active agents in the treatment of metastatic castrate resistant prostate cancer (CRPC) and other variety of cancers. Taxotere has poor solubility and is designed to be administered with Tween 80 in ethanol. This vehicle causes acute hypersensitivity reaction. By removing toxic detergent used in Taxotere, the form of LE-DT, shows reduced toxicity and comparable therapeutic efficacy in pre-clinical study. The clinical evidence obtained from the NeoPharm Phase I study shows fewer side effects and possibly administered at higher dose to induce greater effectiveness of LE-DT. The current Phase II study is designed to accomplish the following objectives: 1. Assess the antitumor effect indicator serum prostate specific antigen (PSA) following the intravenous (IV) administration of 110 mg/m2 LE-DT every three weeks in patients with metastatic castrate resistant prostate cancer 2. To evaluate the measurable soft tissue disease response using the response evaluation criteria in solid tumor (RECIST) methodology 3. To evaluate the progression-free survival (PFS) and overall survival (OS) 4. To correlate PSA expression with tumor response 5. To evaluate the safety of LE-DT at 110 mg/m2 level, in particular peripheral neuropathy, water retention as well as myelotoxicity 6. To evaluate the quality of life (QOL)
NCT00482274
RATIONALE: 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. PURPOSE: This phase II trial is studying how well docetaxel works in treating patients with relapsed prostate cancer.
NCT01226004
To address pertinent questions regarding the utilization of stereotactic Body Radiotherapy (SBRT) to treat prostate cancer. The Florida Robotic Radiosurgery Association (FRRA) launched the first registry for prostate cancer patients treated with SBRT. The registry is designed to track surrogate treatment endpoints including prostate specific antigen (PSA), international prostate symptom score (IPSS),sexual health in men (SHIM), and visual analogue scale (VAS) scores, in addition to physical and survival data. Utilizing an independent vendor (Advertek, Inc.) experienced with the design and implementation of similar electronic registries, FRRA developed a data collection tool that staff members with a basic medical background can use to register and upload pertinent patient data, requiring no more than 20 to 30 minutes per patient. Participating patients will be monitored in follow-up for three years, with analysis and publication of the results semi-annually.
NCT00988208
The purpose of the study is to determine whether lenalidomide is safe and effective for use in combination with docetaxel and prednisone for the treatment of subjects with metastatic Castrate-Resistant Prostate Cancer. The addition of lenalidomide to docetaxel and prednisone is proposed to increase the life expectancy of these subjects.
NCT00838201
The purpose of this study is to describe the safety and tolerability of up to 5 years (ie, 3 years under the 20040138 Amgen study and 2 years on this study) denosumab administration as measured by adverse events, immunogenicity, and safety laboratory parameters in subjects who previously received denosumab for non-metastatic prostate cancer.
NCT01120470
This study is being offered to patients who have castrate-resistant (also known as hormone-refractory) prostate cancer. The cancer has metastasized or spread outside the prostate area to other parts of the body or has recurred in the pelvic area after treatment. The purpose of this clinical research study is to determine whether OGX-427 is able to slow the progression of prostate cancer and symptoms of disease when given with prednisone better than when prednisone is given alone in patients with prostate cancer whose disease has spread outside the prostate area. Research Hypothesis: That adding OGX-427 to prednisone treatment will produce a progression free rate of 20%.
NCT02445976
The goal of this clinical study is to determine the efficacy and safety of Seviteronel, a lyase-selective inhibitor of CYP17 and an androgen receptor antagonist, in patients with castration-resistant prostate cancer (CRPC) who have been previously treated with enzalutamide and/or abiraterone.
NCT01393730
The purpose of this research study is to determine if the addition of dutasteride to a regimen with abiraterone acetate and prednisone will improve on therapy in patients with castrate-resistant prostate cancer and metastatic disease. This study will also help determine the side effects of the study treatment and how often they occur.
NCT02514213
This is a phase I, open-label trial to evaluate the safety and immunogenicity of INO 5150 alone or in combination with INO-9012 when delivered intramuscularly (IM) followed by electroporation (EP) in men with biochemically relapsed prostate cancer.
NCT00925600
This is a phase 3, randomized, double-blind, placebo-controlled study to evaluate new or worsening lens opacifications in men with non-metastatic prostate cancer receiving denosumab for bone loss due to androgen deprivation therapy.
NCT00632905
Prostate Cancer patients treated with LHRH agonists (e.g., goserelin) lose Bone Mineral Density (BMD). Using a prospective, observational study design, we propose that monitoring how physicians manage Cancer Treatment Induced Bone Loss(CTIBL) in their patients. The gold standard for evaluating BMD is dual energy x-ray absorptiometry (DEXA). The proposed study will provide some of the first prospective data on the rates of Skeletal Related Events (SREs) in prostate cancer patients undergoing ADT and help develop official guidelines on the use of DEXA screening for prostate cancer patients.
NCT02429193
This is an open-label phase 2 multi-center study of abiraterone and enzalutamide in men with castration-resistant prostate cancer. Sixteen patients will be enrolled over 18 months.
NCT01512472
Men with localized prostate cancer requiring intermittent androgen deprivation therapy for biochemical recurrence following radical therapy will be asked to participate in a phase 4 safety and efficacy clinical trial comparing 10 months versus 4 months of degarelix (Firmagon®) therapy with the endpoint of prolonging the off treatment interval.
