There are about 189 clinical studies being (or have been) conducted in Venezuela. 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.
Since diabetes has multiple etiologies and oxidative stress one of the proposed mechanisms, the objective is to determine the effect of supplementation with β-carotene to type 2 diabetics and healthy individuals, on iron metabolism, oxidative balance, and antioxidant plasma capacity, using doses similar to the daily nutritional requirement.
In this part of the Registry Program patients with non-valvular atrial fibrillation (AF) at risk for stroke are enrolled to characterize the target population and to collect real world data on important outcome events. For administrative purposes the study is divided into two protocol numbers: 1160.129 for all non-EU (European Union) and non-EEA (European Economic Area) countries, and 1160.136 for EU and EEA countries. The total number of patients enrolled in both protocols is estimated to be 48,000 patients, and all these patients will be included in the data analysis for study 1160.129.
Retrospective, non-interventional, observational multi-center field study. Patients diagnosed with wet Age-related macular degeneration (wAMD) and having started treatment with ranibizumab between January 1, 2009 and August 31, 2009 must be consecutively screened and, if eligible, enrolled. Patients will be followed up at maximum until August 31, 2011. Switch to any other Anti vascUlar endothelial growth factor (anti VEGF) treatment will be documented and followed up. For each patient, demographics, medical history, administered treatments, results of ocular and visual assessments and other tests (where available) will be documented.
This study will describe the long-term safety and effectiveness, treatment patterns,and patient reported quality of life associated with ranibizumab treatment in routine clinical practice for all approved indication included in the local product label.
The aim of the study is to asses the hydration status of incident peritoneal dialysis (PD) patients and its evolution over a period of four years, independent of the PD treatment modality (APD or CAPD) and the PD solution type.
To establish the clinical performance of the SOLX Gold Shunt for its ability to reduce intraocular pressure (IOP) in eyes with refractory glaucoma where medical and conventional surgical treatments have failed.
Background: - Research has shown that the Epidermal Growth Factor Receptor (EGFR) gene is an important target for personalized lung cancer treatment. Individuals who have mutations in the EGFR gene have better responses when treated with certain personalized or targeted therapies compared with conventional chemotherapy. These mutations are more frequent in females with lung cancer who have never smoked, and different ethnic groups have different levels of frequency of the mutations. Researchers are interested in collecting more information on EGFR genetic mutations in Hispanics/Latinos with lung cancer, comparing the frequency of these mutations in males and females and smokers and nonsmokers. This study may lead to better, more personalized care approaches for all individuals with lung cancer. Objectives: - To study the frequency of Epidermal Growth Factor Receptor mutations in Hispanic/Latino individuals who have been diagnosed with non-small cell lung cancer. Eligibility: - Hispanic or Latino individuals who have been diagnosed with non-small cell lung cancer and who have lung tissue from a previous biopsy or surgery available for research purposes. Design: - Participants will provide consent for researchers to examine lung tissue collected from a previous biopsy or surgery. - Treatment will not be provided as part of this protocol.
Treatment of coronary artery disease is a major health care problem across the entire word, and the United States. Unfortunately, despite a number of medical advances, diagnostic procedure, or epidemiological studies, the treatment of these patients remain complex, and and at times frustrating. In fact, the COURAGE trial conducted in 50 centers across United States and Canada documented that drug treatment, coronary interventions or both were not effective solution in coronary artery diseases. A novel approach has recently been developed, based on the critical role of the potassium (K) content in red-blood-cell in myocardial oxygenation, since oxygen and K binding by hemoglobin (red-blood-cell) occurs simultaneously in blood passing through the lungs, whereas in the organs as the heart, the hemoglobin release both Oxygen and K ions. This apparently simple mechanisms occurs in human blood in all individuals but could be altered in subjects with acquired or hereditable defect in red-blood-cell K content. The purpose of this trial, thus, will be to evaluate the pharmacological effects of Amiloride on RBC K-uptake and transport and its impact on reversion of angina, electrocardiographic changes of myocardial ischemia and electrical regeneration of the heart in subjects with coronary artery diseases.
The aim of this retrospective study is to review and describe safety, tolerability and efficacy of Rebif® (subcutaneous interferon [IFN]-beta-1a) in children and adolescents, using information already recorded in medical records. The study duration is 13 July 2010 (first data collected) to 13 July 2011 (last data collected). In this study, Data of the subjects evaluated between 1997 and 2009 was observed.
Primary Objective: To evaluate the efficacy of an intensive insulin regimen with insulin glargine and insulin glulisine in terms of change in Hemoglobin A1c (HbA1c) level from week 12 (visit 7) to week 24 (visit 10). Secondary Objectives: 1. Percentage of patients with HbA1c < 7% at week 24. 2. Percentage of patients with HbA1c < 7% and no symptomatic nocturnal hypoglycemia event at week 24. 3. Fasting Plasma Glucose (FPG) and 7-point Self Monitoring of Blood Glucose (SMBG) at week 0, week 12 and week 24. 4. Doses of insulin glargine and insulin glulisine: the daily dose (U) and the daily dose / kg (U/kg) will be calculated at week 24. 5. Systolic and diastolic blood pressure, heart rate, weight change will be measured at week 0, week 12 and week 24. 6. Number of patients suffering hypoglycemias (asymptomatic, symptomatic, nocturnal symptomatic, severe and nocturnal severe) will be evaluated during the treatment period. 7-Adverse events.
