There are about 25435 clinical studies being (or have been) conducted in United Kingdom. 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 assess the effectiveness and safety of the drug GSK189254 in treating patients with narcolepsy.
The purpose of this study is to test in patients who have had hip replacement surgery the effectiveness (level of pain control) and the safety of 3 different dose levels of CG5503 compared with placebo and with 10-mg oxycodone during the 72-hour double-blind period and to assess the safety of the drug for 9 days after patients completed the double blind period.
This study will assess the safety and efficacy of bosentan therapy (in a study known as ASSET) for patients who have high blood pressure in the lungs associated with sickle cell disease. That form of hypertension places people at risk for complications, including shortness of breath, pain, pneumonia, and death. Previous studies have shown that bosentan can be helpful in reducing pulmonary hypertension. Patients ages 16 and older who have completed the 16-week treatment in the ASSET 1 or ASSET 2 study and who are not pregnant or breastfeeding may be eligible for this study. The research will be conducted in about 25 hospitals in the United States and Europe. Up to 30 participants will be enrolled. The screening visit will involve a physical examination, blood sample of about 3 teaspoons for laboratory tests, and a pregnancy test. Patients' doctors will give them bosentan tablets (62.5 mg each), to take one in the morning and one in the evening. After 1 month, patients will be told whether the dose should be increased to 125 mg tablets to take twice a day. Two weeks after the increase in dose, a blood test will be done to analyze the drug's effects on the liver. After the start of treatment, patients will return for visits every 6 months, when there will be a 6-minute walking test to measure exercise capacity and evaluate shortness of breath. There will be follow-up for patients up to the end of the study and for 28 days after the last dose of bosentan is taken, to collect information about side effects. Some patients on bosentan have had changes in liver function and red blood cell count. Side effects commonly reported are headache, flushed appearance, inflammation of the throat and nasal passages, and gastrointestinal symptoms. If patients have sudden worsening in breathing in the first few weeks after taking bosentan, they should immediately tell their doctors, because it may be necessary to change the treatment.
BMS-275183 given orally twice weekly to patients pretreated for locally advanced or metastatic NSCLC will show anti-tumor activity in any of the 3 separate cohorts of the patients enrolled: - Cohort I: Patients previously treated with one taxane containing regimen. - Cohort II: Patients previously treated with a platinum based but non-taxane containing regimen. - Cohort III: Patients previously treated with both a chemotherapy regimen and one EGFR-TKI (epidermal growth factor receptor-tyrosine kinase inhibitor) compound. Patients in cohorts I and II should have not been treated with a prior EGFR-TKI compound. Prior treatment with a VEGFR (vascular endothelial growth factor receptor) inhibitor compound is allowed for all the patients provided that the VEGFR inhibitor is not also an EGFR inhibitor.
Primary To evaluate the efficacy of satavaptan on top of diuretic drugs in reducing the recurrence of ascites. Secondary To evaluate the tolerability and safety of satavaptan on top of diuretic drugs over a 52-week treatment period in patients with cirrhosis of the liver and recurrent ascites. The one-year double blind placebo controlled period is extended up to 2 years in a long term safety study (PASCCAL-2).
Excessive bleeding is common after cardiac surgery. This may result in patients receiving a blood transfusion or suffering the life-threatening complication of cardiac tamponade. Tamponade is when excessive bleeding compresses the heart and prevents it from pumping properly. A major reason for the bleeding is the damage done to platelets by the cardiopulmonary bypass (CPB) machine. Often patients receive platelets and plasma from blood donors to try to reduce the bleeding post-operatively. The investigators plan to take platelets and plasma from patients before they are damaged. They would then return these 'undamaged' sequestered platelets to the patients after the bypass machine is no longer needed. Therefore, the investigators' primary question is whether platelet sequestration would reduce the bleeding problems that occur following cardiac surgery. They will evaluate bleeding problems using thromboelastography, which provides a comprehensive assessment of both how blood clots form and their strength. If sequestration reduces bleeding problems following cardiac surgery then it may reduce the chance of patients receiving blood products from donors. Although donated blood is thoroughly tested, its use does expose patients to the risk of transfusion errors, blood borne infections and reactions. Avoiding its use would be very desirable.
Fermagate is a phosphate binder that absorbs phosphate from food, reducing the amount that the body can absorb. The purpose of this study it to look at the safety of fermagate over longer periods of time.
To compare efficacy and safety of Exubera® vs Humalog in patients with type 1 diabetes mellitus
To determine the efficacy of ABT-751 when administered in combination with standard docetaxel in subjects with advanced or metastatic NSCLC.
The purpose of this study is to assess the long term (up to 2 years) safety and tolerability of [S,S]-Reboxetine in patients with pain after shingles.
