Active clinical trials for "Prostatic Neoplasms"

This is a phase 1b study that follows a 3+3 dose escalation design and consists of a 21-day lead-in period of oral Polysaccharide Krestin (PSK)/placebo (study drug) alone followed by the addition to study drug of standard intravenous docetaxel at 75 mg/m2 every 3 weeks for three cycles. Study drug will be discontinued on day 15 of the third docetaxel cycle to allow for a 7-day washout period before the fourth dose of docetaxel. Pharmacokinetic (PK) analysis of docetaxel will be conducted during docetaxel cycle 1 (combination therapy) and cycle 4 (docetaxel alone). Serum for future PSK PK analysis will be collected on days 1, 3, and 15 of PSK/placebo lead-in and during cycles 1 and 4.

The purpose of this study is to determine whether female partners of African American men can promote initiation of a discussion with a healthcare provider about prostate cancer screening when the partner is supported by a print message designed to provide relevant information and strategies for her to use in this effort.

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: 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 To evaluate the measurable soft tissue disease response using the response evaluation criteria in solid tumor (RECIST) methodology To evaluate the progression-free survival (PFS) and overall survival (OS) To correlate PSA expression with tumor response To evaluate the safety of LE-DT at 110 mg/m2 level, in particular peripheral neuropathy, water retention as well as myelotoxicity To evaluate the quality of life (QOL)

This is a phase I neoadjuvant gene therapy followed by prostatectomy, open-label, dose-escalation trial for prostate cancer patients with high risk of local recurrence after radical prostatectomy. Patients entered into this trial will have Prostate Cancer of Clinical stage T1c, T2 or T3 with a Gleason Score of between 7 (4+3) and 10 at the time of enrollment. Patients will receive three 1 mL injections (3 mL total volume) of Ad-REIC/Dkk-3 into the prostate prior to undergoing a radical prostatectomy. Three patients will be treated at each dose level unless a dose-limiting toxicity (DLT) is observed or MFD (defined as 1 x 10e12 vp/treatment) is achieved with expansion for up to 6 more patients at the MTD or MFD.

he most common method for performing a prostate biopsy procedure is the ultrasound guided transrectal procedure. The information obtained from the standard prostate biopsy is deficient and even misleading. Cancers can be missed on initial and even in repeated biopsy. Moreover, the detection of a tumor cannot predict accurately the tumor size and location1. It was proven that the exact location of the obtained cores, even in an initial biopsy, can influence the cancer detection rate2. An imaging tool that will enable a three-dimensional navigation in the prostate volume and selecting biopsy locations in view of previous core taken will allow building a "tumor map" '(i.e. detecting tumor size and location). By mapping the prostate cancer an adequate treatment can be chosen while avoiding over or insufficient treatment. However, to be able to produce an accurate mapping of the malignant tissue, a complementary optimized pathology method should be also implement in addition to the navigation system, it has been shown that a pre-embedding procedure that keeps the specimen orientation, unfolding, unity, and location along the needle notch improves the histological yield and hence the cancer detection rate3. The NaviGo™ Workstation (hereafter the NaviGo™ Workstation or the NaviGo™ System) allows physicians to see the prostate gland together with the biopsy sites in a three dimensional (3D) view, modeled from two dimensional (2D) images. The NaviGo™ Workstation was designed as an adjunct to standard of care procedures, to work with standard rectal ultrasound probes, and to be incorporated side by side with the techniques currently employed. No change to the current employed procedures and techniques is required or suggested. In complementary to the Navigo system a system for semi-automatic download of prostate biopsy cores which keeps the orientation, unfolding and unity of the sample was developed to increase the pathology utility. The study objective is to evaluate the contribution of the Navigo™ system, an aiding navigation tool for TRUS prostate biopsy, to an increase in the prostate cancer detection ability.

The purpose of this study is to determine the prostate specific antigen response to continuous low dose oral colchicine.

RATIONALE: Selenium supplements may stop or delay the development of prostate cancer in patients at high risk of prostate cancer. It is not yet known which dose of selenium may be more effective in preventing prostate cancer. PURPOSE: This randomized phase III trial is studying how well selenium works in preventing prostate cancer.

RATIONALE: Antineoplastons are naturally occurring substances that may also be made in the laboratory. Antineoplastons may inhibit the growth of cancer cells. PURPOSE: This phase II trial is studying how well antineoplaston therapy works in treating patients with stage III or stage IV prostate cancer.

The purpose of this research is to develop a new and powerful type of immune therapy for prostate cancer patients. This therapy involves vaccinations with special stimulator cells found in the human body called dendritic cells. These dendritic cells can take up proteins released from cancer cells and present pieces of these proteins to immune cells called T lymphocytes to create a strong stimulatory signal to fight the cancer. One of these proteins is called telomerase, which is found on prostate cancers and is critically important for prostate cancer cells to grow. However, in most cancer patients, the immune system does not adequately destroy the tumor because the T cells are not stimulated sufficiently. T cells require strong stimulation before they grow and become active against cancer cells. We have discovered that substances called ribonucleic acids (RNA), which carry the genetic instructions for the production of telomerase, can be used to overcome this problem and stimulate a strong immune response in cancer patients. In order to test this hypothesis we have designed a clinical study and will enroll patients with metastatic prostate cancer expressing telomerase in order to determine whether or not this vaccine will stimulate T cells, which can recognize and kill prostate tumor cells. The main objectives of this study are to find out whether injections with dendritic cells grown from blood cells and "pulsed" (mixed together for a short period of time) with RNA derived from the patient's own tumor are: Safe without inducing any major side effects. And effective in boosting the patient body's immunity against telomerase expressing prostate cancer cells. Finally, we will test whether or not tumor shrinkage based on serum PSA levels or on X-ray studies will occur. We hope that this new form of immune therapy, although in its infancy, will ultimately slow down tumor growth and prolong survival of prostate cancer patients.

Studies on patterns of how many men get prostate cancer in other countries show that environment contributes to the high incidence of prostate cancer in the United States. Epidemiology studies suggest that this influence may be reduced by the diet of men at risk of getting prostate cancer. Although the exact nature of the effects of diet are not completely known, the amount of fat eaten appears to affect the number of men who get prostate cancer. The type of fat also seems to matter. Eating more of a type of fat called omega-3 polyunsaturated fat is associated with decreased prostate cancer risk. Omega-3 fat comes from fish and is quite different from the type of fat from animals and vegetables (omega-6 fat). Because the exact mechanism of this reduction in prostate cancer risk is not known, no blood test indications, called markers, have been discovered that would show the effect working. Study doctors designed this study to try to find markers in the blood tests of men who have prostate cancer, and to find out if a diet supplemented with omega-3 type fat from fish oil helps reduce those markers, hence indicating that it helps reduce the cancer in these men. These men will be compared to men with prostate cancer whose diets do not contain the fish-oil fat. The men chosen will have prostate cancer and be scheduled for operations to have their prostate glands removed. They will be chosen randomly to be given the fish-oil diet or a regular Western diet for comparison for 4 to 8 weeks. Their blood will be checked at the beginning of the diet. After the 4-to-8-week period, they will have their operations. Their blood will be checked again and a sample of their removed prostate will be examined to tell if the diet had any effect on the cancer and its markers.
