There are about 3982 clinical studies being (or have been) conducted in Argentina. 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 assess growth over time and the clinical course of HCH in children by collecting growth measurements and other variables of interest.
The study is being done to see if ziltivekimab can be used to treat participants living with heart failure and inflammation. Participants will either get ziltivekimab (active medicine) or placebo (inactive substance that looks like the study medicine but does not contain any medicine). The treatment participants get is decided by chance. Participant's chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study is expected to last for up to 1 year and 4 months.
Researchers are looking for a better way to treat people who have chronic heart failure with reduced ejection fraction. Chronic heart failure with reduced ejection fraction (HFrEF) is a long-term condition that occurs when the heart is too weak to pump enough blood to the rest of the body. This results in a reduced supply of the oxygen that the body requires to function properly. The common symptoms of HFrEF include breathlessness, weakness, fatigue, and swelling in the ankles and legs. If left untreated, heart failure can lead to other serious health problems, including damage to other organs, which may result in hospital stays or even death. Vericiguat is an approved drug for use in people with chronic HFrEF. It works by activating a protein called soluble guanylate cyclase, which helps dilating the blood vessels and in turn improves heart function. Currently, treatment with vericiguat starts at a daily dose of 2.5 milligrams (mg), which increases to 5 mg after 2 weeks. The dose is then increased to the target dose of 10 mg after another 2 weeks. In this study, researchers are trying to learn how well participants can tolerate and how safe it is to start vericiguat at a dose of 5 mg. Starting directly at the 5 mg dose is expected to help reach the target dose of 10 mg faster. Participants will take vericiguat 5 mg as a tablet by mouth once daily along with their regular heart medications. At the start of the study, study doctors will check participants' medical history and perform full health check-ups to confirm if they can take part in the study. Throughout the study, study doctors will monitor participants' previous and current medications, their heart health, and their overall well-being. This will help researchers assess how safe the study drug is and if they experience adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective of whether they think they are related to the study treatment. Access to study treatment after the end of this study is not planned. Everyone, including study doctors and participants, will know what drug the participants receive during the study. Participants may be in the study for about 4 weeks. Participants may not benefit from the treatment as the study is designed to assess safety and tolerability: the duration of the study is very short and participants will be taking a low dose of vericiguat without moving to the target dose of 10 mg during the study. However, the findings of this study may enable people with chronic HFrEF to safely skip one initial dosing step and reach the target dose of vericiguat faster. Participants may experience medical problems such as low blood pressure, upset stomach, nausea, dizziness, and headache. Researchers will monitor and manage all these, and other, medical problems participants may have during the study.
The goal of this Multicenter retrospective cohort study is to assessing the association between the development of a tidal volume magnitude > 8 ml/kg of predicted body weight during the first transition to partial support phase in pressure support mode and mortality in the intensive care unit in a general population of patients older than 18 years who require invasive mechanical ventilation, in contrast to individuals who develop tidal volume ≤ 8 ml/kg of predicted body weight. Secondarily, assess the association between elevated VT (tidal volume) during the initiation of the partial support phase in pressure support mode and ventilator-free days, failure in transitioning to spontaneous ventilation, and success in weaning from mechanical ventilation. The main question it aims to answer are: • Does exposure to tidal volumes greater than 8 ml/kg of predicted body weight during the first 48 hours of pressure support mode mechanical ventilation increase the risk of death in the intensive care unit compared to those who develop a tidal volume equal to or less than 8 ml/kg of predicted body weight in subjects older than 18 years requiring invasive mechanical ventilation? The clinical investigation aims to determine whether exposure to tidal volumes greater than 8 ml/kg of predicted body weight during the initial 48 hours of pressure support mode mechanical ventilation is associated with an increased risk of mortality in the intensive care unit when compared to individuals who maintain a tidal volume equal to or less than 8 ml/kg of predicted body weight. This analysis involves subjects aged 18 years and older who require invasive mechanical ventilation
The present clinical study aims to identify transcriptomic patterns derived from whole blood samples related to coronary atherotic burden. Additionally, as a secondary analysis, the research team will explore the algorithm's ability to detect the presence of aortic disease and pro-inflammatory cardiometabolic alterations, such as hepatic steatosis and surrogate markers of coronary inflammation.
Gallstones are relatively frequent in women and constitute one of the main risk factors for gallbladder cancer (GBC). Currently, GBC diagnosis is mainly based on imaging (ultrasound or abdominal CT) associated with invasive examinations (biopsy and surgery), with no marker available to date to accurately predict risk and diagnose the disease early. The only curative treatment for GBC remains surgery with complete resection of tumors in early stages. Given the aggressiveness of GBC and the very limited therapeutic options, as well as the possibility of preventing GBC by cholecystectomy during the 10 to 20 years required for the development of gallbladder tumors, it is imperative to develop effective and efficient prevention strategies based on a prioritization of interventions according to environmental and genetic-molecular risk factors. We aim to identify epidemiological factors linked to the development of GBC, and to identify, validate and functionally characterize genetic-molecular markers in blood, saliva, urine, bile and stool that allow risk prediction, early diagnosis and precision treatment of incidental tumors.
The goal of this observational study is to test the association between baseline ventilatory parameters (in particular mechanical power (MP), mechanical power normalized to predicted body weight (MP/PBW) and driving pressure (DP) with the baseline neurological status (assessed through the Glasgow coma score) in adults patients under mechanical ventilation with acute neurological injury secondary to stroke, brain trauma or subarachnoid hemorrhage. The main question[s]it aims to answer are: 1. In patients with acute neurological injury under mechanical ventilation, is there a correlation between the acute neurological injury, assessed using the Glasgow scale on admission, and baseline ventilatory parameters? 2. In patients with acute neurological injury under mechanical ventilation, are the baseline ventilatory parameters altered at baseline?
This is a parallel, Phase 3, 2-arm study to evaluate the efficacy and long-term safety of dupilumab treatment in children 2 to <6 years of age with uncontrolled asthma and/or recurrent severe asthmatic wheeze. The study will be conducted in 2 parts. Part A will be a 52-week, randomized, double-blind, placebo-controlled study to assess the safety and efficacy of dupilumab in children aged 2 to <6 years old with uncontrolled asthma and/or recurrent severe asthmatic wheeze. At the end of Part A, all eligible participants will be offered participation in Part B, an optional open-label extension phase. Study details include: Part A: The study duration of part A will be up to 68 weeks consisting of a 4-week Screening, a 52week treatment period, and a 12-week post-treatment follow-up period. For participants who will chose to participate in Part B, the study duration will be up to 120 weeks (additional 52-week treatment period). Part B: For participants who will choose to participate in Part B, the study duration will be up to 120 weeks (Part A [4-week Screening and a 52-week treatment period] plus additional 52-week treatment period and a 12-week post-treatment follow-up period).
The primary objective of this study is to assess the efficacy of ALXN2220 in the treatment of adult participants with ATTR-CM by evaluating the difference between the ALXN2220 and placebo groups as assessed by the composite endpoint of all-cause mortality (ACM) and total cardiovascular (CV) clinical events.
Under normal conditions, pain arises as a consequence of the activation of nociceptive afferents (small fibers) by an external stimulus with sufficient intensity to potentially cause tissue damage. This peripheral activation is processed as perception of pain by the central nervous system. In order to reliably evaluate the state of the nociceptive system in both clinical and experimental settings, standardized tests are essential. Quantitative sensory testing (QST) is a set of tests used to measure the intensity of a stimulus that produces a specific sensory perception in a subject. For example, if we gradually apply pressure, the point where the sensation changes from pressure to pain is called the pressure pain threshold. This type of test can be performed with different types of stimuli, including hot and cold stimuli or mechanical stimuli. Although these tests have been shown as reliable in healthy volunteers and pain patients, they are subjective in their nature, since they are based on a conscious evaluation of tested subjects. Likewise, these measures show substantial variability due to differences in the application of the tests by individual examinators. In short, even though the method is quantitative, its methodological characteristics make it subjective and dependent on both the operator and the subject under study. Moreover, contrasting results have been recently found regarding the measurement variability when repeating the QST at intervals of days. Thus, it is essential to investigate and develop new QST alternatives to obtain objective markers that may potentially contribute to the understanding of the mechanisms behind chronic pain conditions.
