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.
Alzheimer's disease (AD) is a progressive and fatal neurodegenerative disease that is manifested by severe cognitive impairment mainly from late life (>65 years). Clinical studies have shown that both systemic inflammation and cortical and hippocampal hyperactivity are features present in patients during the early stages of the disease. In this project we will seek to relate the levels of the proinflammatory cytokines interleukin-1beta, interleukin-6 and tumor necrosis factor-alpha with the level of cortical hyperactivity evaluated with the electroencephalographic changes induced by the GABAergic anesthetic propofol in older adults undergoing elective surgery.
The goal of this observational study is to learn about the effect of general anesthetic on spatial memory in adults who will undergo to an elective surgery. The main question it aims to answer is: • A surgical event under general anesthesia with sevoflurane transiently impairs spatial memory in humans and induces an increase in inflammatory cytokines. Participants will perform a virtual maze test and plasma samples will be taken before and after surgery.
This is a Phase 3 global, multicenter, 52-week, open-label extension (OLE) rollover study for subjects completing study CN012-0026 or CN012-0027. Subjects (randomized or non-randomized) who complete the 38-week CN012-0026 or CN012-0027 study will be eligible to enroll in CN012-0028. The primary objective of the study is to assess the long-term safety and tolerability of KarXT in subjects with psychosis associated with Alzheimer's Disease.
The goal of this observational study is to evaluate the risk factors associated with incident HGD/GA in patients with CAG with or without IM who are enrolled in endoscopic surveillance, as well as to compare GA incidence according to the OLGA and OLGIM scales in patients 18 years or older. . The main questions it aims to answer are: - What risk factors are associated with incident HGD/GA in patients with CAG with or without IM? - What is the comparative HGD/GA incidence according to the OLGA and OLGIM scales?
The purpose of this study is to assess the clinical efficacy, safety, PK, and PD of multiple dose levels of ESK-001 compared with placebo in adult patients with SLE.
This is a multi-center randomized, double-blind, placebo-controlled, parallel, 4-arm study of nalbuphine ER (NAL ER). After meeting eligibility during the Screening Period, subjects will be randomized (1:1:1:1) to one of four treatment arms. - Arm 1: Placebo - Arm 2: 27 mg nalbuphine ER - Arm 3: 54 mg nalbuphine ER - Arm 4: 108 mg nalbuphine ER Each arm will be titrated to their fixed dose during the blinded 2-week Titration period followed by the 4-week Fixed Dose Period for a total of 6 weeks on drug.
This is an observational registry, which main purpose is to assess sex-related differences in heart failure (HF) presentation, management, and prognosis in patients admitted to a hospital with a certain diagnosis of HF. The diagnosis will be based on European Society of Cardiology (ESC) definition of HF ( clinical syndrome characterized by symptoms and/or signs caused by a cardiac abnormality, that results in elevated intracardiac pressure and/or inadequate output at rest or exercise ). The sample will be obtained prospectively by recruitment of patients of two hospitals of Santiago de Chile.
This is a randomized clinical trial with the objective of comparing the time of insertion of two types of perineural catheters in shoulder surgery. These devices are thin lines that have to be inserted over a needle or throw a needle, depending of the type of catheter that is used. The hypothesis is: the installation of Contiplex C or catheter over needle (CON) is faster than a normal contiplex catheter or Catheter throw needle (CTN) at same rate of effectivity.
This is a randomized, double-blind, phase 3 study to evaluate the Efficacy, Safety, and Immunogenicity of ROTAVAC 5D, a live attenuated rotavirus vaccine in healthy infants. A total of 5800 healthy Chilean infants will be recruited in this study and randomized to receive either vaccine or placebo in 1:1 ratio. Among these participants 300 will be categorized to immunogenicity cohort, 150 from each group, and blood samples will be collected to assess the immune response.
The goal of this trial is to assess in healthy subjects between 60 and 70 years the effect of glycemic and glycoxidative postprandial responses and platelet aggregation after intake of bread supplemented with Chilean beans flour when compared with a non supplemented control. The main questions to answer are: - It is possible to decrease postprandial glycemic and glycoxidative responses by means of the intake of bread supplemented with Chilean beans flour when compared to the intake of a control bread non supplemented in healthy elderly persons? - How is affected the platelet aggregation process during postprandial state after intake of bread supplemented with Chilean beans flour, when compared to the intake of a control bread non supplemented in healthy elderly persons? Participants will: - Be characterized by means of: 1) evaluation of body composition, using anthropometric techniques, bioimpedance and 2) biochemical analyses: biochemical profile, lipid profile, serum ferritin, fasting glycemia, HbA1c and insulin. - Arrive at fast to the laboratory and eat randomly control bread, 30% Chilean beans supplemented bread or glucose. Venous blood samples will be taken from the cubital fossa of the dominant arm at: 0, 30, 60 and 120 min postprandial, only after intake of bread control and supplemented bread. In addition, capillary blood will be taken at 0, 15, 30, 60, 90 and 120 min postprandial after intake of glucose, bread control or supplemented bread.
