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.
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
To provide access to maraviroc to patients who have limited or no therapeutic treatment options and to collect more safety data in a broader patient population.
Vestibular stimulation has been shown to be a very effective noninvasive treatment for major depression. Bipolar disorder is a mental illness that presents cyclic sequences of depressive and euphoric states. Depressive phases of bipolar disorder are difficult to treat and usually are resistant to actual available treatments. This study investigates the effectiveness of a particular technique of vestibular stimulation in a group of 120 bipolar type I and II patients. After randomization 60 of them will receive specific vestibular stimulation (experimental group) and 60 will receive a sham vestibular stimulation.The study will conducted in Vest Brain, Centro de Estudios Neurovestibulares, in Chile.
In patients ≥ 60yrs with acute ST-elevation myocardial infarction randomised within 3 hours of onset of symptoms the efficacy and safety of a strategy of early fibrinolytic treatment with half-dose tenecteplase and additional antiplatelet therapy with a loading dose of 300 mg clopidogrel, aspirin and coupled with antithrombin therapy followed by catheterisation within 6-24 hours or rescue coronary intervention as required, will be compared to a strategy of primary PCI with a P2Y12 antagonist and antithrombin treatment according to local standards.
Primary Objective: To describe the pharmacokinetic (PK) profile of sarilumab in patients aged 2-17 years with Polyarticular-course Juvenile Idiopathic Arthritis (pcJIA) in order to identify the dose and regimen for adequate treatment of this population Secondary Objective: To describe the pharmacodynamic (PD) profile, the efficacy and the long-term safety of sarilumab in patients with pcJIA.
This is a double blinded, randomised controlled trial that will compare atropine to placebo for postoperative pain in laparoscopic gynaecological surgery
NPC1L1 is a key transporter in the enterohepatic cycle of cholesterol. Initial in vitro and in vivo data show that blocking this receptor with ezetimibe results in delaying infection in these models. The investigators hypothesize that HCV has an enterohepatic cycle, being secreted in bile and reabsorbed either in the canalicular membrane or in the intestine by association with NPC1L1, following a path similar to the cycle of cholesterol in humans. To prove this hypothesis the investigators propose to assess the effect of ezetimibe treatment in HCV infected individuals undergoing liver transplantation to avoid or delay HCV infection. For this purpose, the investigators propose to administrate ezetimibe 10 mg/d for 12 weeks to 12 patients with chronic hepatitis C infection listed for a liver transplantation.
This randomized, Phase I/III, multicenter, double-blinded, placebo-controlled study was designed to evaluate the safety and efficacy of atezolizumab (anti-programmed death-ligand 1 [PD-L1] antibody) in combination with carboplatin plus (+) etoposide compared with treatment with placebo + carboplatin + etoposide in chemotherapy-naive participants with ES-SCLC. Participants will be randomized in a 1:1 ratio to receive either atezolizumab + carboplatin + etoposide or placebo + carboplatin + etoposide on 21-day cycles for four cycles in the induction phase followed by maintenance with atezolizumab or placebo until progressive disease (PD) as assessed by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1). Treatment can be continued until persistent radiographic PD or symptomatic deterioration.
A study to determine the concordance of key actionable genomic alterations as assessed in tumor tissue and plasma from patients with non small cell lung carcinoma (NSCLC)
The purpose of this study is to evaluate whether a new model of health care for chronic patients, based on Case Management and guided by a nurse which targets the patient´s risk, is more effective than usual care at Primary Health care in Chile. Additionally, this intervention would provide a better quality of care and a more efficient health provision.
