NCT00001117
This study evaluates patients infected with both HIV and Hepatitis C virus (HCV) who are receiving anti-HIV drugs. The purpose of this study is to learn more about HCV infection in patients whose HIV blood level decreases to less than 500 copies/ml.
NCT00220467
The specific aims for the study will be to determine if aerobic exercise enhances cognition for older adults who are at greater risk for developing Alzheimer's disease, and to evaluate whether change in insulin sensitivity predicts cognitive performance for subjects randomized to the aerobic exercise group. Sedentary older adults diagnosed with mild cognitive impairment will participate in a 6-month supervised protocol of either aerobic exercise or stretching. Cognitive testing and blood collection will occur at baseline, and months 3 and 6. Before and after the 6-month intervention, insulin sensitivity, maximum aerobic capacity, and body fat composition and distribution (via CT scan) will be assessed for all subjects. The results of this study may provide support for a relatively simple and inexpensive treatment strategy that specifically targets many of the health factors that directly influence risk of cognitive decline for older adults.
NCT00001109
The purpose of this study is to learn more about some of the immune cells in the blood (CD4 cells, for example) of healthy children in order to better understand the differences in the blood cells of children infected with HIV. Because children's bodies are still developing, their cells are different from those of adults, and their bodies respond differently to infections such as HIV. In order to understand how immune cells grow and mature so that they can fight HIV, it is important to see how these cells behave in normal children.
NCT00006643
The purpose of this study is to find if the Single Photon Emission Computed Tomography (SPECT) scan is as effective as a liver biopsy (using a special needle to remove tissue from the liver) in examining liver damage in patients with HIV and hepatitis C virus (HCV). A standard way to examine the liver for disease has been to perform a liver biopsy. The SPECT scan, which takes a picture of the liver, has been found to be effective in determining liver damage but studies need to be done in patients with hepatitis. This study will compare the effectiveness of the liver biopsy and SPECT scan in determining liver disease in patients with HIV and HCV. The SPECT scan might be a good replacement for the liver biopsy if it is found to be as good as or better than liver biopsies.
NCT00202488
The purpose of this study is to determine if Helicobacter pylori (H. pylori) gastritis results in abnormal iron metabolism in patients with iron deficiency anemia (IDA), and to determine if this is due to strain variations in the H. pylori organism.
NCT00298350
The purpose of this study is to evaluate the non-inferiority of ritonavir-boosted GS-9137 relative to a ritonavir-boosted Comparator Protease Inhibitor when used as part of combination antiretroviral regimens in subjects who have failed, or are failing, protease inhibitor therapy.
NCT00003647
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Injecting allovectin-7 into a person's melanoma cells may make the body build an immune response that will kill tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of dacarbazine with or without immunotherapy in treating patients who have stage III or stage IV melanoma.
NCT00039156
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of BAY 59-8862 in treating patients who have refractory non-Hodgkin's lymphoma.
NCT00650455
The objectives of the study were to evaluate the efficacy, safety, and tolerability of valdecoxib 10 mg once daily (QD) or naproxen 500 mg twice daily (BID) versus placebo, and to assess the efficacy of valdecoxib 10 mg QD versus naproxen 500 mg BID, in treating the signs and symptoms of rheumatoid arthritis (RA) in a severe Rheumatoid Arthritis population.
NCT00575822
The aim of this study was to determine the effectiveness of endoscopic full-thickness plication (Plicator; NDO Surgical, Inc., Mansfield, MA) for the treatment of GERD in comparison to a sham procedure. Patients with symptomatic GERD requiring maintenance proton pump inhibitor therapy were entered into a randomized, single-blind, prospective, multicenter trial. Seventy-eight patients were randomly assigned to undergo endoscopic full-thickness restructuring of the gastric cardia with transmural suture. Eighty-one patients underwent a sham procedure. Group assignments were revealed following the 3-month evaluation. The primary endpoint was ≥ 50% improvement in GERD-HRQL score. Secondary endpoints included medication use and esophageal acid exposure. Patients achieving ≥ 50% improvement in GERD-HRQL score at 3-months versus baseline off-meds were considered responsive to their assigned procedure. Patients who failed to reach this level of improvement at 3-months were considered non-responders. Analysis of these dichotomized variables (responder/non-responder) was done using Fisher's exact test comparing the proportion of responders between the active and sham groups. Intent-to-treat analysis was also performed. The null hypothesis was that the proportion of responders was the same in both the active and sham groups. Testing was done at the 5% level of significance (alpha=0.05).
NCT00584896
The purpose of this study is to determine if the use of PB127 with cardiac ultrasound assists in the diagnosis or exclusion of coronary artery disease.
NCT00584714
The purpose of this study is to collect longer term follow-up information concerning health and survival on selected patients who received PB127 for injectable suspension in the pivotal trial (127-014).
NCT00029822
A study to determine the effect on prevention of Acute Urinary Retention (inability to urinate) in males with an enlarged prostate, also known as BPH. * Free study-related medical care provided.
NCT00199550
This study will prospectively evaluate a new electrosurgical procedure (bipolar transurethral prostatectomy) in men with symptomatic benign prostatic hyperplasia.
NCT00396214
The primary objective of the study is to evaluate changes in weight short and long term with bifeprunox and quetiapine. Study participation for the subject is 57 weeks.
NCT00706680
This study has been designed to test whether using Thymoglobulin with low dose Cyclosporine and early steroid dosage reduction will minimize both kidney rejection and the development of new onset diabetes mellitus after renal transplant.
NCT00595673
This trial is to compare PB127 echocardiography to other heart imaging studies.
NCT00105976
The purpose of this clinical study is to see if an experimental drug, called MM-093, is safe and effective in the treatment of rheumatoid arthritis. MM-093 is a genetically engineered version of a naturally occurring protein called alpha fetoprotein (AFP). Adults normally have very small amounts of AFP in their bloodstream. However, during pregnancy, AFP levels in both the mother and the fetus are much higher than normal. It has been observed that women with RA (Rheumatoid Arthritis) have fewer symptoms during pregnancy, particularly during the third trimester. At this time, the levels of AFP in the blood of the mother and fetus are the highest. This observation led researchers to begin examining AFP as a possible treatment for RA.
NCT00345774
This study is being conducted to see if PRX-08066 can lower pulmonary artery pressures in patients with pulmonary hypertension associated with chronic obstructive pulmonary disease.
NCT00537628
Primary Objectives 1. Mid Region pro Adrenomedullin (MR-proADM) is superior to BNP for the prognosis of heart failure (HF) patients and adds incremental value in predicting outcomes for patients presenting to the Emergency Department (ED) with shortness of breath. 2. Mid Region pro A-Type Natriuretic Peptide (MR-proANP) is non-inferior to BNP for the diagnosis of HF in patients presenting to the ED with shortness of breath.
