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.
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.
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard adjuvant endocrine therapy for patients with ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy). The planned duration of treatment in either arm within the study will be 7 years.
The purpose of this study is to assess the safety and tolerability and to confirm the dose of nemtabrutinib in combination with venetoclax in participants with R/R CLL/SLL. The primary study hypotheses are that the combination of nemtabrutinib plus venetoclax is superior to VR with respect to progression-free survival (PFS) per 2018 International Workshop on Chronic Lymphocytic Leukemia (iwCLL) criteria as assessed by blinded independent central review (BICR).
This project seeks to evaluate the effect of transcranial alternating current stimulation (tACS) on the recovery of motor control of the upper limb and associated neuronal synchrony during a 14-sessions (5-week) rehabilitation program for adult patients with diagnosis of stroke at chronic stage. Specifically, the stimulation on Gamma ranges, because the evidence available so far allows us to propose that the tACS in the Gamma range (around 70 Hz) facilitates motor execution. For this purpose, the experimental approach involves active (70 Hz in Gamma rhythm and 7 Hz, Theta rhythm) and sham tACS together with an analytical and integrated motor training with a double-blind and randomized design. Our hypothesis is that Gamma frequency tACS restores neuronal synchrony in Beta range, which enhances the upper limb motor recovery associated with a training program. Using specific motor control parameters, clinical scales and electroencephalography, the immediate and long-term (3 months after finished the training) behavioral and neurophysiological effect of this new neurostimulation paradigm (tACS plus training) for motor rehabilitation of stroke will be established.
The purpose of this study is to assess the safety and efficacy of two doses of Deucravacitinib in adult participants with Active Sjögren's Syndrome.
The primary objective of the study is to determine the effect of seralutinib on improving exercise capacity in subjects with WHO Group 1 PAH who are FC II or III. The secondary objective for this trial is to determine time to clinical worsening.
The purpose of this study is to learn if V940 which is an individualized neoantigen therapy (INT; formerly, called messenger ribonucleic acid [mRNA]-4157) with pembrolizumab (MK-3475) is safe and prevents cancer from returning in people with high-risk melanoma. Researchers want to know if V940 with pembrolizumab is better than receiving pembrolizumab alone at preventing the cancer from returning.
Gastric cancer remains a global health problem, and Chile has one of the highest GC mortality rates in the region. Helicobacter pylori (H. pylori) infection is ubiquitous in Chilean adults, and it constitutes the main cause of GC worldwide. A long-term process occurs from premalignant lesions to carcinoma. H. pylori eradication during early stages of disease significantly impacts outcomes, favoring survival, disease reversal and molecular changes, which supports a "screen and treat" strategy in asymptomatic populations in areas with intermediate-to-high GC prevalence. The Investigators' previous research has shown that H. pylori infection is acquired in early childhood with low rates of spontaneous eradication. A pilot treatment study in a subset of school-aged asymptomatic children showed a high rate of successful eradication (>95%), good tolerance, and was associated with a decrease in serum biomarkers of gastric damage (pepsinogen I and II). Based on the results of these studies, the Investigators propose to advance towards the next stage of this research process: a "screen and treat" strategy. The current trial starts with a Screening phase testing 1000 asymptomatic adolescents 14-18 years of age from 3 cities of Chile (Colina, Temuco and Coyhaique), to find a total of 200-250 persistently-infected participants. Persistently-infected adolescents will be included in a Second phase of this trial: A randomized, case-control, non-blinded study to either receive antimicrobial treatment targeting H. pylori eradication (cases) or no treatment (controls). A subset of 60 non-infected adolescents will be followed-up in matched times. This aims to provide evidence on the effect of treatment on clinical outcomes and serum biomarkers related to gastric damage, as well as composition and antimicrobial resistance of gut microbiota. The Investigators expect that eradication therapy will be successful in >90% of persistently infected adolescents, with reinfection rates not surpassing 15% in a 2-3 year period, and to be associated with a decrease in clinical findings indicative of gastric disease, and a decrease in serum biomarker indicative of "gastric damage".
