NCT02689206
GSK1278863 is an orally available, hypoxia-inducible factor - prolyl hydroxylase inhibitor, currently being investigated as a treatment for anemia associated with chronic kidney disease. GSK1278863 has been given as a once daily regimen in clinical studies to date. However, physicians in countries that use a three-times weekly hemodialysis schedule prefer to give the anemia medicine at the same time as the dialysis session. This study will test how well GSK1278863 can maintain hemoglobin levels when given three-times weekly, for 29 days. This study will describe the relationship between hemoglobin and GSK1278863 given three-times weekly. The data from this study will allow for conversion of once daily doses to three-times weekly doses.

NCT01866826
Background: * Human immunodeficiency virus (HIV) treatment can control the amount of virus in the blood, but it does not provide a cure. The reasons why HIV treatment does not cure the infection are not well understood. HIV persists in blood cells for years, even if people receive treatment for it. In addition, HIV infection leads to an activated immune system, which can cause other problems. * One theory for why HIV infection causes immune activation involves the intestinal tract. HIV infects immune cells the intestine soon after infection and damages their immune barrier. This damage lets bacteria cross into the bloodstream, leading to ongoing inflammation. Even when a person with HIV feels well, this chronic inflammation may affect the immune system. Researchers want to see if the antibiotic Rifaximin can reduce this inflammation. Rifaximin is designed to stay inside the digestive system, so it affects only bacteria in the intestines. Objectives: \- To see if Rifaximin can reduce bacteria-related inflammation in people with HIV. Eligibility: \- Individuals at least 18 years of age who have HIV infection and are taking medications to treat it. Design: * Participants will be screened with a physical exam, blood test, and medical history. * Participants will take either Rifaximin or a placebo for 4 weeks. They will have no medication for 4 to 6 weeks, and then take the other drug for 4 more weeks. * During the study, participants will have frequent blood and urine tests. They will also provide stool samples. Liver and kidney function tests will be performed. HIV viral load (the amount of virus in the blood) will also be studied. * Participants will have a final follow-up visit after an additional 4 weeks. * Two additional tests are optional for study participants: * Two blood draws: one on the third day after starting Rifaximin, and one on the third day after starting the placebo. * Up to three colonoscopies of the lower intestine and biopsies of the intestine. These studies will collect samples of the intestinal tract to look at the effects of Rifaximin in the study.
NCT00339677
This study will evaluate the structure of error in self-reporting instruments on diet, in following up the Observing Protein and Energy Nutrition Study (OPEN) conducted in 1999 and 2000. The OPEN study, the largest of its kind, resulted in a wealth of nutritional biomarker data-measurable indicators of changes in organisms at the level of molecules or cells. A biomarker could help in understanding how environment and disease are related and about disease risks. Furthermore, its findings showed that the relative estimates of disease risk may be weakened by a food frequency questionnaire and a 24-hour questionnaire. Scientists have long recognized that self-reported information from questionnaires and interviews contains errors, but there has been uncertainty about the structure of such errors. For the proposed study, a food record and a food checklist-adjusted food frequency questionnaire will be compared with the previously used questionnaires, to determine whether the newer study instruments present less chance of measurement error. The results may provide better tools for a study on nutritional epidemiology, that is, the incidence and other aspects of disease and nutrition. OPEN study participants will be invited for follow-up. Patients who completed the 1999-2000 study who are not currently pregnant or a liquid weight loss diet may be eligible for this study. The original study recruited men and women 40 to 69 years of age. A letter with summary results from the original OPEN study will be sent to each of the 482 participants. Both the Food Record and the food checklist, called the Daily Food List, are instruments to be given. The Food Record asks the participant to record all foods and beverages consumed. The Daily Food List asks respondents to write in to the number of times a limited number of food categories are consumed. In addition, respondents will be asked to complete the National Cancer Institute Diet History Questionnaire (DHQ), identical to the one that they completed in the original OPEN study, regarding the previous 12 months. Participants will randomly be assigned to one of two groups. All will receive four study mailings over a 3-month period: the DHQ, First 4-Day Food Record (4-day FR), Second 4-day FR, and Booklet of 7-Day Food Lists (7-day FL), the latter listing selected foods that the participants will mark if consumed on the reporting day. Study Group A will receive the DHQ, first 4-day FR, second 4-day FR, and 7-day FL. Study Group B will receive the DHQ, 7-day FL, first 4-day FR, and second 4-day FR. Within 10 days after receiving the DHQ, participants will be called to schedule an appointment for a 30- to 45-minute visit. Participants will undergo the following procedures: * Complete the Physical Activity Questionnaire (by telephone for those who have moved out of the local area or are unable to attend the visit) * Have weight measured * Be asked about whether he or she has recently developed certain medical conditions, experienced dramatic changes in diet, or gained special education in nutrition The completion time for each instrument in dietary assessment is approximately as follows: * DHQ-60 minutes. * Each 4-day FR-80 minutes (20 minutes a day). * 7-day FL-35 to 49 minutes (5 to 7 minutes a day).

NCT00727441
RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an effective immune response to kill pancreatic cancer cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vaccine therapy together with cyclophosphamide may kill more tumor cells. It is not yet known whether vaccine therapy is more effective with or without cyclophosphamide in treating patients with pancreatic cancer. PURPOSE: This randomized clinical trial is studying the side effects of vaccine therapy and to see how well it works when given with or without cyclophosphamide in treating patients undergoing chemotherapy and radiation therapy for stage I or stage II pancreatic cancer that can be removed by surgery.
NCT00836407
Research Hypothesis: Ipilimumab (an antibody that blocks negative signals to T cells) administered alone or in combination with a pancreatic cancer vaccine (allogeneic pancreatic tumor cells transfected with a GM-CSF gene), has an acceptable safety profile in subjects with locally advanced, unresectable or metastatic pancreatic adenocarcinoma. Primary Objective: To determine the safety profile of ipilimumab alone or in combination with a pancreatic cancer vaccine in subjects with locally advanced, unresectable or metastatic pancreatic adenocarcinoma. Secondary Objectives: * To estimate overall survival (OS) which will serve as the primary efficacy signal. * To explore an association of T cell responses and immunological responses with OS in patients receiving treatment. * To estimate overall response rate (ORR), immune related best overall response rate (irBOR), progression free survival (PFS), and duration of response in patients receiving treatment. * To explore an association between immune-related adverse events (IRAEs) and ORR. * To measure tumor marker kinetics (CA 19-9) in patients receiving treatment.

NCT01967810
This is a Phase 2 study to see if an investigational drug, ANG1005, can shrink tumor cells in patients with high-grade glioma. Another purpose of this study is to assess the efficacy, safety, tolerability, and pharmacokinetics (PK) of ANG1005 in patients.
NCT00081289
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Chemoradiotherapy (combining chemotherapy with radiation therapy) before surgery may shrink the tumor so that it can be removed. Giving chemotherapy after surgery may kill any remaining tumor cells. PURPOSE: This randomized phase II trial is studying two different regimens of neoadjuvant chemoradiotherapy and adjuvant chemotherapy and comparing how well they work in treating patients who are undergoing surgical resection for locally advanced rectal cancer.
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.
NCT02525523
A Phase III, multi-centre, double-blind randomised controlled trial in subjects with chronic antibiotic refractory pouchitis. Subjects will undertake a \<2 week screening period to provide baseline data and be assessed for eligibility. At the Baseline visit (Day 1) eligible subjects will be randomised on a 1:1 basis to either a) 240 mg alicaforsen enema or b) matching placebo. Study drug will be administered once nightly (on going to bed) up to and including week 6. Following the Day 1 Visit, subjects will return to the clinic for safety and efficacy assessments at Week 3, 6, 10, 18 and 26. Subjects may receive certain permitted medications as per Entry Criteria, which must remain at stable doses throughout the trial. Introduction of any new medication for pouchitis, or a dose change to an existing concomitant medication for pouchitis, other than those detailed in the protocol, will not be permitted. Clinical symptoms associated with pouchitis will be recorded daily by the patient in a diary card. Subjects will undergo endoscopic examination of their pouch (during Screening, and at Weeks 6 and 10). Where technically feasible, each endoscopy will provide at least one biopsy sample for histopathology. In addition to endoscopic, histopathologic and symptomatic assessments, Quality of Life will be assessed. Bloods for routine assessment, including haematology and biochemistry will be taken. Bloods and stool samples will be collected to evaluate relevant biomarkers.
NCT02066311
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease in which the body's immune system attacks different parts of the body. SLE is characterized by inflammation that leads to tissue damage in different organ systems. Any organ system may be involved, including the skin, the joints, the kidneys, the nervous system, the heart, the lungs, and the blood. The exact cause of SLE is not known. Patients with SLE often have elevated levels of anti-double stranded DNA antibodies. These levels are often associated with disease flares and disease severity. These antibodies can bind to tissue leading to organ damage. Preventing these antibodies from binding to their targets may help decrease disease activity. Protease inhibitors are medications that have been approved by the Food and Drug Administration (FDA) for use in the treatment of HIV (human immunodeficiency virus). Nelfinavir (also called viracept) is one of these protease inhibitors. Separate from their anti-viral effects, protease inhibitors have been found to decrease inflammation. These medications have been shown to interfere with binding of anti-double stranded DNA antibodies to their targets and may decrease inflammation in SLE. This research study tests whether the protease inhibitor, nelfinavir, will decrease anti-double stranded DNA antibody binding and decrease disease activity.
