NCT01143077
Lurasidone (lurasidone HCl) is a novel psychotropic agent that is being developed as a potential new antipsychotic treatment for patients with schizophrenia. Switching between antipsychotic medications is common in the treatment of schizophrenia. The current study is designed to evaluate the effectiveness, safety, and tolerability of switching clinically stable, but symptomatic outpatients with schizophrenia or schizoaffective disorder from their preswitch antipsychotic medication to lurasidone, over a period of 6 weeks.
NCT00924469
The purpose of this study is to evaluate safety and efficacy of abiraterone acetate plus leuprolide acetate and prednisone, versus leuprolide acetate alone in male participants with prostate cancer (a disease in which cells in the prostate gland become abnormal and start to grow uncontrollably, forming tumors) who are suitable candidates for prostatectomy (surgery to remove all or part of the prostate gland).
NCT00347555
Malaria is an illness caused by a parasite (an animal or plant that lives in or on a host) that enters the human body through the bite of an infected mosquito. The purpose of this study is to find out about the safety of an experimental malaria vaccine and whether the vaccine causes humans to produce antibodies (proteins made by the body's immune system to help control or prevent infection). Four strengths of the vaccine will be tested. The lowest strength of the vaccine will be tested before the next higher strength is tested. Each dosage (shot) of vaccine will be given to 18 people in 4 dosage groups on Day 0, at 1 month and at 6 months. Two people in each dosage group will receive injections of a placebo (contains no medication). Participants will include 80 healthy adults between 18 and 40 years of age. Multiple blood draws will occur over the duration of the study. Participants will be involved in study related procedures for approximately 13 months.
NCT00003386
RATIONALE: Vaccines made from tumor tissue may make the body build an immune response and kill tumor cells. PURPOSE: Phase II trial to study the effectiveness of vaccine therapy in treating patients who have stage III or stage IV ovarian epithelial cancer.
NCT00756847
The purpose of this study is to evaluate the safety and tolerability of XL147 in combination with paclitaxel and carboplatin in adults with solid tumors. XL147 is a new chemical entity that inhibits PI3 Kinase. Inactivation of PI3K has been shown to inhibit growth and induce apoptosis (programmed cell death) in tumor cells. In clinical practice, the combination of paclitaxel and carboplatin is an accepted treatment regimen for various solid tumors, including ovarian cancer, endometrial cancer and non-small cell lung cancer (NSCLC).
NCT00205777
The purpose of this study is to determine whether bazedoxifene acetate is safe and effective in the treatment of osteoporosis in postmenopausal women.
NCT00525980
This project will build upon prior, successful research on the effectiveness of an interactive computer disk with readable only memory (CD-ROM) for educating women about breast cancer and genetic risk. Prior studies found that an interactive CD-ROM for educating women about breast cancer risk and genetic testing was effective. The program was well received by lay persons and professionals. In a randomized controlled trial conducted at multiple sites, the CD-ROM intervention was highly effective in increasing knowledge, especially among women at low risk of carrying a breast cancer susceptibility gene 1/2 (BRCA1/2) mutation. Researchers now propose to expand the use of the interactive CD-ROM in two innovative ways. The overall goal of this proposal is to evaluate the program as a first-line educational approach for Hispanic women on the Texas-Mexico border, where educational resources about cancer genetics are limited. First, researchers will modify and adapt the program for a primarily Hispanic population, in order to make it culturally and linguistically appropriate to the needs of that audience. Second, researchers will evaluate the program as a first-line educational method among women with a personal or family history of breast cancer. Researchers will compare the effectiveness of the CD-ROM when implemented with and without the guidance of a trained promotora, and in comparison with standard educational materials (usual care condition). The specific aims of this study include: Aim 1: To modify the interactive CD-ROM to: a) make it culturally and linguistically appropriate for Hispanic women residing along the Texas-Mexico border; b) reflect current knowledge about breast cancer genetics; c) add a module to help women prepare to discuss their family history and cancer risk with a health care provider (n=50 participants). Aim 2: To conduct a randomized, controlled evaluation that compares the efficacy of the modified CD-ROM when used alone vs. when used with a promotora-assisted approach vs. standard written materials (n=414 participants).
NCT00429182
The goal of this clinical research study is to learn the relationship of high-dose chemotherapy (HDCT) and circulating tumor cells (CTCs) in controlling metastatic breast cancer. The study also will investigate the role of CTCs in breast cancer.
NCT00054405
Phase I trial to compare the effectiveness of interleukin-12 with or without interleukin-2 in treating young patients who have refractory or recurrent neuroblastoma. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining interleukin-2 with interleukin-12 may kill more tumor cells.
NCT00003908
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of docetaxel plus carboplatin in treating patients who have metastatic or recurrent head and neck cancer.
NCT00006708
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. It is not yet known whether combination chemotherapy is more effective with or without rituximab for non-Hodgkin's lymphoma. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without rituximab in treating patients who have relapsed or refractory non-Hodgkin's lymphoma.
NCT00699777
This study is a randomized, open-label, crossover study to assess the bioequivalence of 1 risedronate 150 mg tablet versus 2 risedronate 75 mg tablets administered as a single oral dose. Approximately 320 subjects will be enrolled from 4 study centers in the U.S.
NCT00003316
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of gemcitabine in treating patients with recurrent or refractory cancer of the uterus.
NCT00909545
The primary purpose of this study is to establish a dosage of isradipine CR that is tolerable and demonstrates preliminary efficacy for utilization in future pivotal efficacy studies.
NCT00002819
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells. It is not yet known whether chemotherapy alone is more effective than chemotherapy plus peripheral stem cell transplantation for ovarian epithelial cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of paclitaxel and carboplatin with that of carboplatin, mitoxantrone, and cyclophosphamide followed by peripheral stem cell transplantation in treating patients who have persistent stage III or stage IV ovarian epithelial cancer.
NCT01171404
The aim of this international study is to describe the short- and long-term (i.e. up to 2 years following the index event) antithrombotic management patterns (AMPs) in patients hospitalized for acute coronary syndromes (ST segment elevation myocardial infarction (STEMI), Non-ST-Segment Elevation Acute Coronary Syndrome (NSTE-ACS)), and to document the impact of AMPs in clinical outcomes, economic variables and quality of life in a 'real-life' setting and to compare these between sites, countries and regions.
NCT00035893
This is an open-label, prospective, randomized, controlled study of the safety and efficacy including clinical, immunologic, and virologic assessments of adding Ampligen to a Strategic Therapeutic Intervention (STI) of HAART in patients with plasma HIV RNA \< 50 copies/ml (PCR) and CD4 levels \> 400.
NCT00035581
This is an open-label, prospective, randomized, controlled study of the safety and efficacy including clinical, immunologic, and virologic assessments of adding Ampligen to "HAART" in HIV infected patients with CD4 counts \>300 and HIV-1 plasma RNA \>500 and \<30,000 copies/ml (PCR).
NCT00316849
This phase I trial is studying the side effects and best dose of temsirolimus when given together with temozolomide and radiation therapy in treating patients with newly diagnosed glioblastoma multiforme. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving temsirolimus together with temozolomide and radiation therapy may kill more tumor cells.
NCT00828594
