There are about 9745 clinical studies being (or have been) conducted in Israel. 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.
CYP2C9, is one of the major drug metabolism enzymes accounting for about 20% of the hepatic cytochrome P450 content and being second only to CYP3A4. The proposed study will explore different possible drug interactions with CYP2C9 substrates by evaluating the effect of prototype inducers and inhibitors on the phenotypic trait measurement. It is expected that the identification of drugs that might interact with CYP2C9 substrates will be used to rationalize future drug interaction studies designed to evaluate the actual magnitude of effect and its clinical implications. This approach should be particularly useful when applied to those CYP2C9 drugs characterized by a narrow therapeutic index (i.e. warfarin). This study will consist of three study periods separated from each other by a two weeks washout period. In the course of the study the subjects will receive in a double blind, crossover fashion, rifampin 300 mg. twice daily, diclofenac 50 mg twice daily. and fluconazole 200 mg. twice daily, each for one week. All drugs will be administered as identical looking tablets that will be prepared at the pharmacy of the Hadassah University Hospital and their order of administration will be randomized.On the day prior to, on day 6 of and 7 days following each drug period, the activity of CYP2C9 will be evaluated by the administration of a single phenytoin 300 mg. dose. The subjects will be requested to collect their urine for 24 hours and a single blood sample will be obtained 12 hours post phenytoin intake.
This trial is intended to find wether there is a connection between allergy to metals and reooclusion of stents in the coronary arteries
Multi-institutional randomized phase III trial of a non-myeloablative preparative regimen with fludarabine and busulfex with or without anti-lymphocyte antibodies (monoclonal humanized Campath-1H administered s.c. or polyclonal rabbit anti-T lymphocyte antibodies (ATG), combined with low dose and short course cyclosporine A (CSA) and methotrexate (MTX) as the sole agent for prevention of graft-vs-host disease (GVHD) for patients with acute myelogenous leukemia or myelodysplastic syndrome undergoing allogeneic stem cell transplantation from an HLA compatible donor.
This study will determine the effectiveness of treatment with glycine or d-cycloserine in addition to a normal antipsychotic regimen in improving negative symptoms and cognitive impairments in patients with schizophrenia.
The purpose of this study is to determine whether Vitamin E treatment to Diabetic patients, who carry the Haptoglobin 2-2 Phenotype, prevents cardiovascular complications such as acute MI and Stroke.
The trial will study 2 doses of Immune Globulin Intravenous (Human), 10% Caprylate/Chromatography Purified (IGIV-C) for the number of relapses that occur in a 1 year treatment period.
The intent of this study is to demonstrate the efficacy and safety of Immune Globulin Intravenous (Human), 10% Caprylate/Chromatography Purified (IGIV-C) in newly or previously diagnosed CIDP subjects. Eight courses of treatment with either placebo or IGIV-C will occur every 3 weeks. Neurological function will be measured by Inflammatory Neuropathy Cause and Treatment (INCAT) scores. Patients who deteriorate or show no improvement between day 16 and month 6 will receive the alternate study drug for an additional 6 months.
To determine whether therapy with Modafinal(Provigil) is safe and effective in fatigue in MS Patients
Scientific background: Growing awareness and accumulating data regarding the cognitive impairment and its progression in multiple sclerosis (MS) patients has received an important place in neurological research in the last decade.
The primary objective of this multicenter study is to evaluate the efficacy of escitalopram in treatment resistant depression (TRD), assessed by 2 consecutive failed antidepressant treatments from different classes. The last treatment received is a 6 week prospective trial with venlafaxine.
