A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer Clinical Trials Facts presented on Clinical Trials Search is not designed to be a substitute for certified medical advice, travels to or treatment with a real dr.. We aren't doctors. Always consult your mD on A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer Clinical research trials and A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer medical trials occur in many of places across the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectiveness of new does drugs. The role of the studies / undertakings is to figure out certain human healthcare questions. Clinical trials are a popular means for doctors, government agencies, and private sector corporations to locate treatments for all forms of circumstances, including A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer. A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer Clinical Trials and other clinical trials permit volunteers to get medical treatment options before they are available to the masses. Most times the human subjects acquire treatment for free of charge, and sometimes they are paid for their time. Occasionally there is a cost for a A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer clinical trial. Participants oftentimes recieve the finest healthcare available for their A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer condition. Dangers are a reality, nonetheless, and might include extra or frequent physician calls, health hazards (potentially life-endangering), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials subjects.

A Randomized Phase II Study of Oral Thalidomide in Patients with Hormone-Refractory Prostate Cancer
For Condition: Prostatic Neoplasm
Status: Completed
Sponsor(s): National Cancer Institute (NCI) ,
Synopsis: This is a phase II study designed to evaluate the potential clinical efficacy of thalidomide in patients with hormone-refractory prostate cancer. An important aspect of this study is to characterize the pharmacokinetics of thalidomide, as well as make correlations between the degree of angiogenesis occurring in a patient and the activity of thalidomide.
Details: This is a phase II study designed to evaluate the potential clinical efficacy of thalidomide in patients with hormone-refractory prostate cancer. Patients will be randomized to two different treatment arms (low dose versus high dose). An important aspect of this study is to characterize the pharmacokinetics of thalidomide, as well as make correlations between the degree of angiogenesis occurring in a patient and the activity of thalidomide. Each patient that has biopsiable lesions will undergo a pretreatment biopsy of their prostate (or other site of soft tissue disease) and repeat after 2 to 6 months of treatment. Additional information will be obtained on the changes in the circulating levels of the following growth factors: bFGF, TNF, VEGF, and TGFB. Neurological complications are the primary dose-limiting toxicity anticipated with chronic thalidomide administration.
Eligibility:
Study Type: Interventional, Treatment, Safety/Efficacy

New bone metastasis on Tc-99 bone scintigraphy. Progression of measurable or evaluable soft-tissue metastases. Development of new area of disease. 25% increase in previously measured lesions. Total androgen ablation required. Testosterone in castrate range. Concurrent luteinizing hormone-releasing hormone (LHRH) agonist required if not surgically castrated.
