There are about 2320 clinical studies being (or have been) conducted in Chile. 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 aim of this study is to compare the efficacy of methadone versus morphine in dealing with postoperative pain, in laparoscopic cholecystectomy under total intravenous anesthesia (TIVA); Efficacy is defined in terms of the difference of milligrams in morphine used as rescue analgesia postoperatively. Our hypothesis is that methadone is more effective than morphine for postoperative pain treatment.
The primary purpose of this study is to evaluate the safety for 2 different rivaroxaban treatment strategies and one Vitamin K Antagonist (VKA) treatment strategy utilizing various combinations of dual antiplatelet therapy (DAPT) or low-dose aspirin (ASA) or clopidogrel (or prasugrel or ticagrelor).
Dystrophinopathy is a disease continuum that includes Duchenne muscular dystrophy, which develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of dystrophinopathy in approximately 10-15 percent (%) of boys with the disease. Ataluren is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. The main goal of this Phase 3 study is to evaluate the effect of ataluren on walking ability. The effect of ataluren on physical function, quality of life, and activities of daily living will be evaluated. This study will also provide additional information on the long-term safety of ataluren.
The rationale behind this clinical performance investigation is to collect data regarding the usability of the Baha Attract System in patients with hearing impairment that are candidates for Baha surgery: - To describe the expected hearing performance with the Baha Attract in comparison to unaided hearing thresholds or a pre-test situation using a sound processor together with a softband - Which sound processor to select, i.e. BP100 vs BP110 - Improve the fitting process for the sound processor - Selection of sound processor magnet at time of fitting and over time
This is a multicenter, randomized, double-blind, double-dummy, parallel group study. The purpose of this study is to compare the efficacy and safety of umeclidinium/vilanterol (UMEC/VI) and fluticasone propionate/salmeterol (FSC) in subjects with COPD. Subjects who meet the eligibility criteria at Screening will complete a 7 to 14 day Run-in period. At the end of the run-in period, approximately 710 eligible subjects will be equally randomized (to complete at least 568 evaluable subjects) to one of the 2 treatment groups for 12 weeks: 1. UMEC/VI 62.5/25 micrograms (mcg) administered as one inhalation once-daily in the morning via the Novel dry powder inhaler (NDPI) + placebo administered as one inhalation each morning and evening via single multidose powdered inhaler (ACCUHALER/DISKUS) or 2. FSC 250/50 mcg administered as one inhalation each morning and evening via ACCUHALER/DISKUS + placebo administered once-daily in the morning via NDPI. A safety Follow-up assessment will be conducted approximately 7 days after the end of the study treatment (Early Withdrawal, if applicable). The total duration of subject participation will be approximately 15 weeks.
This study will evaluate whether low-density lipoprotein (LDL-C) lowering with evolocumab (AMG 145) results in greater change from baseline in percent atheroma volume (PAV) at week 78 than placebo in adults with coronary artery disease taking lipid lowering therapy.
The purpose of this trial is to make a comparison between the use of antiseptic silver alloy-coated silicone urinary catheters and the use of conventional silicone urinary catheters in spinal cord injured patients to prevent urinary infections.
The Irritable Bowel Syndrome (IBS) is a frequent disease, affecting between 10 and 20% of general population. Several pathophysiologic mechanisms have been described in IBS, among them the role of intestinal microbiota and small intestinal bacterial overgrowth (SIBO) have received special attention. SIBO has an adequate response to antibiotic treatment, unfortunately it didn't have an adequate diagnostic test: The classic gold standard -jejunal aspirate culture- has been criticized due to lack of standardization; the breath tests are simpler and widely available, but they have also been criticized due to inadequate diagnostic accuracy for SIBO. For this reason seems important to evaluate the performance of breath tests in terms of predicting clinical benefit of antibiotic therapy in IBS patients, rather than predicting a positive culture and SIBO. The objectives of this study are: 1. Determine which breath test (lactulose or glucose) predicts better a potential clinical benefit of antibiotic treatment (Rifaximin) in IBS patients. 2. Determine which of the multiples diagnostic criteria described for the lactulose breath test predicts better a potential clinical benefit Rifaximin in IBS patients.
The purpose of the study is to evaluate the potential role of plasmatic Fibroblast Growth Factor 23 (FGF-23) as a prognosis predictor of clinical outcomes in Critical Care patients.
This international study is a prospective noninterventional observational cohort study of patients with non-valvular atrial fibrillation who are prescribed rivaroxaban under routine treatment conditions to prevent stroke or non-central nervous system systemic embolism. Patients will be followed up for 1 year or until 30 days after end of rivaroxaban therapy in case of therapy was discontinued earlier than 12 months. Serious adverse events will be followed up adequately. Laboratory values (e.g., Hb, HCT, haemoccult) should be documented for each point in time they were measured.
