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 if high-dose cyclophosphamide followed by a maintenance dose of glatiramer acetate is safe in patients with relapsing remitting multiple sclerosis (MS). The investigators hypothesize that institution of glatiramer acetate treatment following high-dose cyclophosphamide treatment will extend the period of disease free activity and further reduce the disability in patients with relapsing remitting multiple sclerosis. The investigators plan to investigate the properties of glatiramer acetate against the recurrence of MS disease activity following high dose cyclophosphamide induced cessation detectable autoimmunity. The investigators hypothesize that glatiramer acetate, given in the phase of immune reconstitution after high-dose cyclophosphamide, may bias the immune system to a more tolerated state, thus leading to more stable and potentially permanent remissions.
To assess the possibility that treatment with Kuvan (a form of tetrahydrobiopterin) will lessen the abnormal behavior and/or neurology commonly found in Lesch-Nyhan disease (LND); to assess biochemical changes as measured in blood and urine.
The purpose of this study is to determine if taking green tea capsules can help prevent weight gain in patients that start therapy with Zyprexa® (olanzapine).
The standard treatment for head and neck cancer relapses in previously irradiated patients is controversial. Reirradiation has had some success, but many patients still die from their disease. Cetuximab is helpful in relapsed head and neck cancer, and it improves the effectiveness of radiation in some head and neck cancer patients. But, it has not been studied with reirradiation. The purpose of this study is to see the effects, both good and bad, of reirradiation with cetuximab.
Positron Emission Tomography Imaging with 3-Deoxy-3'-[18F]Fluorothymidine (FLT) can selectively identify proliferating and non-proliferating tissues, including tumors. FLT uptake in the tumor is an indirect marker of DNA synthesis activity, which is a target of chemotherapy. Our hypothesis is that early change in FLT uptake in tumor with chemotherapy will predict pathological response to neoadjuvant therapy in breast cancer. Tumor uptake of FLT will be imaged and measured with positron emission mammography (PEM), a PET scanner optimized for breast imaging with a significantly improved resolution compared to conventional whole-body PET imaging systems.
The primary objective of this prospective, randomized study is to compare cosmetic outcomes between absorbable and non-absorbable sutures in truncal and extremity lacerations in the pediatric and adult population. Secondary outcome measures include wound complications such as infection and wound dehiscence at the initial visit; and parental satisfaction and keloid formation after three months post repair.
This is a multi-center study designed to assess the accuracy and precision of the Cholestech LDX Cardiac hsCRP test for the quantitative determination of C-reactive protein (CRP) in whole blood, serum and plasma from individuals being assessed for risk of cardiovascular disease. The Cholestech LDX Cardiac hsCRP test consists of the CRP cassette and LDX analyzer and measures CRP with high sensitivity on fingerstick or venous whole blood at the point-of-care (POC). The results of this study are intended to be used for regulatory 510k filings for use as an in vitro diagnostic test.
This study is being done to determine if the drug known as dexmedetomidine improves the way we care for patients when their surgery involves the use of a tourniquet on the leg. A tourniquet is sometimes used for lower leg or foot surgery to decrease the blood loss for the patient and to make it easier for the surgeon to do his work.
The purpose of the proposed study is to determine the effectiveness of methylphenidate HCl (Concerta) in college students with ADHD. This study will consist of 110 college students between the ages of 18 and 25 who are enrolled full-time in a local or junior college. The study consists of an 8-week double-blind, placebo-controlled trial of placebo versus methylphenidate HCl (Concerta®) followed by a 10-week extension of open label methylphenidate HCl (Concerta®).
Hepatitis C is the most common reason for liver transplantation in the United States and affects nearly 4 million Americans. Treatments for hepatitis C are available but are poorly tolerated and are not always effective. Morbidity and mortality from hepatitis C are related to the development and progression of hepatic fibrosis to cirrhosis and end stage liver disease. Efforts to block progression of liver disease would thus result in prevention of morbidity and mortality as well as costs incurred by the health system in the care of these conditions. Scar tissue in the liver is secreted by a type of cell, called the stellate cell, in an activated state. This cell carries a receptor for angiotensin, a hormone, when activated. If this receptor is blocked, the cell becomes inactive and does not participate in scar tissue formation. Thus, we hypothesize that using a drug such as candesartan, which blocks angiotensin receptors, should result in less scar tissue formation in the livers of patients with hepatitis C.
