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 study will be comparing tivozanib in combination with nivolumab to tivozanib alone in subjects with advanced Renal Cell Carcinoma (RCC) who have had 1 or 2 prior lines of therapy, one of which was an Immune Checkpoint Inhibitor (ICI).
Chagas Disease, caused by the parasite Trypanosoma cruzi afflicts 7 million people in Latin America, and due to migration, abroad. The diagnosis lies in clinical suspicion and serologic detection of antibodies. Cardiac evaluation is essential because complications, including heart failure and arrhythmias, are the main causes of disability and death. Heart involvement is explained by a parasite-dependent, immune-mediated myocardial and microvascular injuries. Current treatment includes the administration of nifurtimox or benznidazole, although in the chronic phase their efficacy is low and may induce severe adverse events, forcing the suspension of the therapy. Therefore, finding innovative approaches to improve the efficacy of the current antichagasic drugs by modifying the inflammatory response would render the current treatment more effective. Pre-clinical evidence supports the idea that the cholesterol-lowering statin drugs, such as atorvastatin, may contribute to decrease cardiac inflammation, reduce endothelial activation, and improve cardiac function. Atorvastatin therapeutic and safety profiles are well known, as is its mechanism of action, shared by the other members of the statin class. This trial aims at evaluating whether atorvastatin, in combination with antichagasic therapy, is safe and more efficacious in reducing general inflammation than an antiparasitic therapy alone, by improving endothelial and cardiac functions. This proof-of-concept trial will be double-blinded, randomized, and multicentered with a phase II design. To achieve this aim, it will be evaluated the efficacy of the combination of atorvastatin and antichagasic therapy (nifurtimox or benznidazole) to reduce inflammatory cytokine plasma levels, soluble endothelial cell adhesion molecules, and confirm the improvement of the cardiac function by electrocardiogram and two-dimensional echocardiogram. The trial will set the safety and tolerability of the combination of atorvastatin with antichagasic therapy by monitoring the incidence of adverse events and discontinuation of the therapy. This trial will be conducted with a sample size of 300 adult patients in four hospitals located in Santiago and Valparaiso, Chile.
Intensive care unit (ICU) survivors and their families frequently present mental, cognitive and physical impairments lasting years. The ongoing pandemic could affect the duration, variety, and severity of these impairments. Our aim is to determine the impact of the COVID-19 pandemic on the physical, mental, and cognitive health of survivors, the experience of their families and their treating healthcare professionals in the long-term. This is a prospective, multicentre, mixed-methods cohort study in seven Chilean ICUs. The perceptions of family members regarding the ICU stay and the later recovery will be explored 3 months after discharge. Health care professionals will be invited to discuss the challenges faced during the pandemic using semi-structured interviews.
The purpose of this study is to determine the safety and efficacy of belzutifan in combination with pembrolizumab and lenvatinib in multiple solid tumors including hepatocellular carcinoma (HCC), colorectal cancer (CRC), pancreatic ductal adenocarcinoma (PDAC), biliary tract cancer (BTC), endometrial cancer (EC),and esophageal squamous cell carcinoma (ESCC). There is no formal hypothesis testing in this study.
The purpose of this study is to evaluate long-term safety and tolerability of dapirolizumab pegol treatment.
Older patients are more prone to adverse cognitive outcomes such as postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). Both conditions are associated with an increased risk of death, functional decline, and health care costs. The presence of pro-inflammatory cytokines in the central nervous system has detrimental effects on the regulation of neurotransmitter signaling in different areas of the brain, especially the hippocampus, ultimately resulting in neuronal dysfunction and cognitive decline. Neuroimaging studies have provided important information on the structural and functional networks involved in the pathogenesis of POD and POCD. Strong evidence has shown a decrease in the integrity of the default mode network (DMN), along a continuum from normal aging to mild cognitive impairment and Alzheimer's disease. Dexmedetomidine is a highly selective alpha-2 adrenergic agonist with sedative and analgesic properties but minimal respiratory effects. Several studies have shown that dexmedetomidine reduces serum pro-inflammatory cytokines and POCD. The expected results are to analyze the change in the integrity of the DMN from the preoperative period to the first weeks after discharge given by the two anesthetic strategies (SEVO vs SEVODEX). In addition, it seeks to evaluate (1) Changes in the integrity of the DMN at 3 months. (2) Modulation of structural changes in white matter integrity as measured by DTI. (3) Patient performance in specific cognitive function tests and serum inflammation biomarkers between the pre- and postoperative period. For the analysis, the Generalized Linear Model (GLM) will be used, in which the integrity of the DMN is the dependent variable. As predictors will use the anesthetic groups (SEVO and SEVODEX) and the measurement time (preoperative, 1 to 3 weeks after discharge and 3 months later as levels). With this work we aim to provide a mechanistic explanation of the observed neuroprotective effects of dexmedetomidine in anesthesia protocols for elderly patients. Furthermore, this work will possibly promote functional connectivity as a possible clinical biomarker of cognitive impairment in this vulnerable population.
A Multicenter Retrospective Study to understand the clinical characteristics, treatment pathway and resource utilization for patients with chronic lymphocytic leukemia A retrospective, multi-centre, observational study to describe disease characteristics, treatment patterns, treatment-related outcomes, and resource utilization for Chronic Lymphocytic Leukemia (CLL) patients in multiple international regions
This is a Phase III, global, randomized, open-label, multicenter, study evaluating the efficacy and safety of adjuvant giredestrant compared with endocrine therapy of physician's choice in participants with medium- and high-risk Stage I-III histologically confirmed estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative early breast cancer. In addition, an open-label exploratory substudy will explore the safety and efficacy of giredestrant in combination with abemaciclib in a subset of the primary study population.
EVITA is a multicentric Latin-American prospective cohort on chronic hypersensitivity pneumonitis. EVITA's objective is to identify phenotypes and/or endotypes associated with different disease trajectories measured primarily by forced vital capacity (FVC) during a 24 month follow-up period. Other secondary measures of disease progression will also be investigated such as imaging, time to death or lung transplantation, and patient-reported outcomes
A global phase 3, multicenter, randomized, trial, to Determine the Efficacy and Safety of Durvalumab in combination with Tremelimumab and Enfortumab Vedotin or Durvalumab in combination with Enfortumab vedotin for Perioperative Treatment in Patients Ineligible for Cisplatin or who refuse Cisplantin Undergoing Radical Cystectomy for Muscle Invasive Bladder Cancer. The goal of the study is to explore the triplet combination of Durvalumab, Tremelimumab and Enfortumab Vedotin in terms of efficacy and safety compared to the current Standard Of Care (SOC). Volga trial consists of two parts: Safety Run-In and Main Study. In total the study aims to enroll approximately 830 patients, who will receive triplet combination, duplet combination of Durvalumab and Enfortumab vedotin or currently approved SOC in the main trial. In the main part of the trial there is two out of three chances of being on a treatment arm and the treatment is assigned at random by a computer system. In this trial patients in the two treatment arms will receive either 3 cycles of neoadjuvant Durvalumab + Tremelimumab + Enfortumab Vedotin or Durvalumab + Enfortumab vedotin and after surgery both treatment arms will continue with adjuvant Durvalumab.
