There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to determine the effects of different amounts of phosphorus in the diet on hormones that control phosphorus and bone health both in people who are healthy and in ones who have moderate kidney disease.
The purpose of this study is to determine whether dietary supplementation with Lactobacillus GG will reduce the rate of failure or relapse following treatment of CDAD with metronidazole.
Evaluate for difference in outcome between hospital admission versus discharge after recent TIA, and evaluate feasibility of a larger study.
The purpose of this trial is to quantify the amount Celebrex, a specific cyclooxygenase-2 (COX-2) inhibitor, when used for the management of acute renal colic for a ureteral stone will: - reduce pain medication usage - improve the percentage of spontaneous stone passage - decrease the time to spontaneous passage, and - shift the size distribution of stones passed towards larger sizes
This is a randomized controlled trial of testosterone replacement therapy in hypogonadal men age > 60 years. The goal is to assess the safety and efficacy of TRT in men age > 60 years.
This study will test an experimental antiviral drug called SIGA-246 for use against the smallpox virus (variola). Although smallpox has been universally eradicated, it could possibly be brought back as a bioweapon. In the event of a smallpox attack, it would be best to have an antiviral medication in addition to the smallpox vaccine. SIGA-246 has shown to have activity against other viruses from the same family (orthopoxvirus) that smallpox belongs to. Healthy volunteers who are 18-50 years of age and are not pregnant or breastfeeding may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, and an electrocardiogram. Participants are randomly assigned to receive a one-time dose of SIGA-246 (either 500 mg, 1000 mg, or 2000 mg) or a placebo (sugar pill) taken by mouth. They report to the clinic in the morning for the following procedures: - Insertion of intravenous (IV) line in the forearm. - Blood and urine tests before taking the study drug. - Drug administration within 30 minutes of eating a light breakfast. - Blood sampling from the IV line at 30 minutes and at 1, 1.5, 2, 2.5, 3, 3.5, 4, 5 and 6, 10 and 12 hours after taking SIGA-246 to determine how the drug is absorbed, distributed, broken down and excreted. Samples are also collected by needle stick at 24 and 48 hours for the same tests. - Electrocardiogram at 2 hours and 24 hours after taking SIGA-246. - 24-hour urine collection after taking the SIGA-246. - Complete diary card at home for 7 days after taking the SIGA-246. - Follow-up visits at about 2 weeks and about 4 weeks after taking SIGA-246. - Checks for health changes or problems at every visit.
RATIONALE: Drugs used in chemotherapy, such as busulfan and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy with a peripheral stem cell or bone marrow transplant may allow more chemotherapy to be given so that more cancer cells are killed. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Tacrolimus and methotrexate may stop this from happening. PURPOSE: This phase II trial is studying how well giving busulfan together with fludarabine before donor stem cell transplant works in treating patients with hematologic cancer.
This study is an open-label, fixed-dose, multicenter study of MDX-060 in patients with ALCL who have relapsed or refractory disease. There will be 3 phases of this study: Induction, Maintenance, and Follow-up. Patients will be required to attend all protocol-required visits in the 4-week Induction Phase, in which administration of MDX-060 will occur, as well as other testing. Patients who complete the Induction Phase may be eligible for additional MDX-060 treatment ever 2 months for 1 year in the Maintenance Phase. Patients who complete the Maintenance Phase with a response of stable disease or better will be followed every 2 months for 1 year or until disease progression. The purpose of this study is to determine objective response rate at Day 50 in patients with relapsed or refractory classic systemic ALCL or primary cutaneous ALCL treated with MDX-060. Other objectives will be evaluated.
The Tissue Repository will search for cases, pull slides, Paraffin-embedded tissue (PET) blocks.
The purpose of this study is to determine what percentage of patients receiving high-dose Cyclophosphamide may experience a halt in the worsening of their disease or experience improvement of their disease and for how long the benefit may last.
