Filter by:This is a randomized, double blind, multi-institutional phase II therapeutic study of Indoximod or placebo after the completion of standard of care sipuleucel-T (Provenge®) in men with asymptomatic or minimally symptomatic metastatic prostate cancer that is castration resistant (hormone refractory). Patients are randomized to receive either twice daily oral Indoximod or placebo for 6 months beginning the day after the third and final sipuleucel-T infusion.
This study is designed to evaluate the safety of biweekly cabazitaxel for the treatment of metastatic castration resistant prostate cancer (mCRPC) patients previously treated with docetaxel containing regimen. The primary endpoint is safety. Secondary endpoints include time to treatment failure, response rate, overall survival and quality of life.
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.
Biomarkers of bone resorption will be measured in the blood of patients with bone metastases from prostate cancer during the course of their illness. Changes in these biomarkers will be correlated with the patient's treatment with antiandrogen therapy and bisphosphonates and the response and/or progression of their cancer. It is hoped that serial measurement of these biomarkers may allow therapeutic monitoring in the future with successful individualisation of bisphosphonate therapy for metastatic prostate cancer.
Bone is the most common site of metastases in prostate cancer and bone complications cause substantial morbidity to this population. Phase III studies have shown that zoledronic acid is effective in decreasing the morbidity associated with bone metastases. Zoledronic acid (ZA) is generally well tolerated but may have side effects such as hypocalcemia, renal impairment and osteonecrosis of the jaw. Administration of ZA as infrequently as once yearly is sufficient to prevent osteopenia or osteoporosis. The optimal treatment interval is unknown, but the drug is often empirically administered every 3-4 weeks. The cost of such treatment is high, and the risk of exposing patients (especially those at low risk) to potential serious side effects with uncertain benefit warrants investigation. This study will determine the duration of suppression of bone turnover in prostate cancer patients with bone metastases following a single infusion of Zoledronic Acid and its effect on quality of life.
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. Dietary supplements, such as phytochemicals, may stop or delay the development of prostate cancer.
Background: - Prednisone and docetaxel have been used successfully in treating patients with prostate cancer, either when used alone or in combination with other agents. Researchers believe that these anticancer effects can be increased by giving them in this specific combination. - A previous study at the National Cancer Institute combined docetaxel and prednisone with bevacizumab and thalidomide. The results of this study were promising; however, most patients in the study required a dose reduction of thalidomide because of its side effects. - Lenalidomide, a drug similar to thalidomide, may have less severe side effects. Based on previous studies, lenalidomide is well tolerated in patients with solid tumors when used alone or in combination with docetaxel, and it may be a good substitute for thalidomide. Objectives: - To determine if lenalidomide is an appropriate and effective substitute for thalidomide in treating prostate cancer. - To evaluate the safety and effectiveness of bevacizumab, lenalidomide, docetaxel, and prednisone as a prostate cancer treatment, and to study any side effects. Eligibility: - Men 18 years of age and older who have been diagnosed with metastatic prostate cancer that has not responded to standard treatment, including surgical removal of the testicles or treatment with androgen (sex-hormone) suppressing drugs. Design: - Participants will have a complete medical history and physical examination before beginning the study. - Patients will be treated with 21-day cycles with a combination of four drugs: - (1) Docetaxel, which will be given into a vein for 60 minutes on the first day of each 21-day cycle. Patients will take dexamethasone (a steroid agent) before and after taking docetaxel. - (2) Prednisone, which will be taken by mouth daily. - (3) Bevacizumab, which will be given through a vein over 30 to 90 minutes on the first day of each 21-day cycle following the infusion of docetaxel. - (4) Lenalidomide, which will be taken by mouth during the first 2 weeks of each 21-day cycle. The dose of lenalidomide may be adjusted if side effects develop. - Patients will also receive enoxaparin, a subcutaneous injection administered daily, to prevent blood clots and/or pegfilgrastim, a subcutaneous injection on day 2 of each cycle, to improve white blood cell counts, as directed by researchers.
The purpose of this research study is to find out what effects (good and bad) Sutent has on you and your prostate cancer.
we propose to randomize patients with hormone resistant prostate cancer between docetaxel/estramustine/prednisone and docetaxel/prednisone in a phase II study. The principal endpoint will be the efficacy in term of PSA response.
The purpose of this study is to find the recommended doses of dasatinib and docetaxel given in combination to men with metastatic hormone refractory prostate cancer and to assess the pharmacokinetic interactions between the 2 drugs.
