NCT ID: NCT00160095 Completed - Larynx Cancer Clinical Trials

Patient Selection for Hypoxia Modifying Treatments in Larynx Carcinomas

Start date: July 2001
Phase: Phase 3
Study type: Observational

The purpose of this study is to identify in a prospective manner microregional profiles of oxygenation and proliferation based on exogenous and endogenous markers that are predictive for outcome of radiotherapy in squamous cell carcinoma of the larynx and to investigate if these profiles can identify patients that are most likely to benefit from hypoxia modifying treatment strategies like ARCON (Accelerated radiotherapy combined with carbogen breathing and nicotinamide).

NCT ID: NCT00160056 Completed - Diabetes Clinical Trials

The Effect of Antecedent Hypoglycaemia on β2-adrenergic Sensitivity

Start date: April 2005
Phase: N/A
Study type: Interventional

Hypoglycaemia unawareness is a common complication in patients with type 1 diabetes and with insulin-treated type 2 diabetes of long duration. The loss of autonomic symptoms to hypoglycemia does not solely depend on loss of adrenaline responses.Differences in sensitivity to catecholamines may also be involved. Reconciling the data on β2-adrenergic receptor polymorphism to those on loss of β-adrenergic sensitivity in diabetic patients with hypoglycemia unawareness, we hypothesize that hypoglycemia unawareness is at least partly the result of desensitization of the β2-adrenergic receptor and that patients who are homozygous for arginine at codon 16 are particularly susceptible for this desensitization process, whereas patients who are homozygous for glycine at codon 16 are resistant for desensitization. Objectives 1. To determine whether, and if so to what extent, antecedent hypoglycemia reduces β2-adrenergic sensitivity in healthy subjects with Arg16 homozygosity. 2. To investigate whether or not healthy subjects with Gly16 homozygosity are resistant to desensitization 3. To confirm that antecedent hypoglycemia reduces the heart rate response to isoproterenol and to assess to what extent this reduced response is mediated by impairments in baroreflex sensitivity.

NCT ID: NCT00160017 Completed - Clinical trials for Diabetes Mellitus, Non-Insulin-Dependent

Effectiveness and Cost-effectiveness of the Diabetes Integrated Care Breakthrough Collaborative

Start date: January 2005
Phase: N/A
Study type: Observational

The study tests whether implementing professional evidence-based guidelines and best practices for diabetes care -through participation of multidisciplinary teams in a Breakthrough collaborative- results in an improvement of diabetes care, its health outcomes and economic costs. Determinants of success are studied. Data on diabetes will also be used to better understand Breakthrough as an implementation or improvement method.

NCT ID: NCT00159887 Completed - Clinical trials for Pulmonary Hypertension

Study to Assess the Longterm Safety of Sildenafil Citrate in Patients With Pulmonary Arterial Hypertension

Start date: December 2002
Phase: Phase 3
Study type: Interventional

Open label extension study to the pivotal efficacy study to assess the safety of sildenafil citrate in patients with pulmonary arterial hypertension

NCT ID: NCT00159861 Completed - Clinical trials for Pulmonary Hypertension

The Efficacy and Safety of Sildenafil Citrate Used in Combination With Intravenous Epoprostenol in PAH

Start date: July 2003
Phase: Phase 3
Study type: Interventional

Determination of the effects of sildenafil citrate and epoprostenol when used in combination in patients with pulmonary arterial hypertension

NCT ID: NCT00159835 Completed - Clinical trials for Cardiovascular Diseases

Atorvastatin Versus Simvastatin In The Prevention Of Coronary Heart Disease (CHD) In Patients With Known CHD

IDEAL
Start date: February 1999
Phase: Phase 4
Study type: Interventional

To investigate whether a long-term strategy to lower LDL cholesterol with atorvastatin as much as possible will improve prognosis in CHD patients compared with a strategy reflecting current best clinical practice with simvastatin.

NCT ID: NCT00158899 Completed - Dyslipidaemia Clinical Trials

GW501516 In Subjects Who Have Low Level Of High-Density Lipoprotein Cholesterol

Start date: August 2004
Phase: Phase 2
Study type: Interventional

The purpose of this clinical research study is to compare up to 3 doses of an investigational drug GW501516 to placebo (an inactive pill that looks like GW501516) to see if it is safe, well tolerated and effective in improving (raising) low levels of "good cholesterol", high-density lipoprotein cholesterol (HDLc), as compared to placebo.

NCT ID: NCT00158873 Completed - Sedation Clinical Trials

Pharmaco-Economic Study Of Ultiva In Intensive Care Unit(ICU)Subjects

Start date: September 2004
Phase: Phase 4
Study type: Interventional

The study will evaluate the pharmaco-economic consequences of the use of a remifentanil based regimen compared with a conventional sedative based regimen in terms of duration of mechanical ventilation, length of stay in ICU, difference in extubation time and use of concomitant sedative agents.

NCT ID: NCT00158834 Completed - Asthma Clinical Trials

Pediatric Asthma Study Using Stepwise Treatment With Two Food And Drug Administration Approved Asthma Medications

Start date: November 1999
Phase: Phase 3
Study type: Interventional

This study was designed to evaluate if, in children with asthma, a stepwise treatment (five levels varying from once daily fluticasone propionate 100mcg until twice daily a fixed combination of salmeterol and fluticasone propionate 50/500 mcg) based on symptom scores alone results in a sub-optimal treatment when compared to treatment based on cumulative symptom scores and bronchial hyperresponsiveness (PD20 methacholine).

NCT ID: NCT00158782 Completed - Clinical trials for Carcinoma, Renal Cell

Study Of Safety And Tolerability Of GW786034 Given With Lapatinib In Cancer Patients

Start date: September 28, 2004
Phase: Phase 1
Study type: Interventional

This Phase I, dose finding study evaluates the safety and tolerability of lapatinib, a dual tyrosine kinase inhibitor, and GW786034, an anti-angiogenesis agent, when given together. The study first will find the best doses using safety and blood concentration data of both agents. This is done enrolling stepwise, cohorts of 3 patients each and the last patient enrolled must reach at least Day 22 of continuous daily dosing before the next cohort at an increased dose can begin. If a patient in a cohort has a dose limiting toxicity before Day 22, then 3 more patients are studied at that same dose. If 2 of 6 patients have dose limiting toxicities within the first 22 days, the next cohort receives the next lowest dose. Otherwise each cohort has an increasing dose of one of the two agents. The second stage of the study will administer the best doses of the agents to about 16 patients to further study safety and collect more blood concentration data (more blood samples in the second phase compared to the first phase). The second stage has the advantage of using the best dose (decreases chance of receiving a sub-therapeutic dose) while it collects more blood samples and requires slightly more long clinic visits.
