Participants will be randomized to receive either a placebo or one of the active treatments. This record describes the default procedures and analyses for all cohorts. Each specific cohort may have additional eligibility requirements, safety and efficacy procedures, or endpoints, which will be described in the corresponding intervention-specific records on clinicaltrials.gov listed below in the detailed description.
NCT07123961
Acute respiratory distress syndrome (ARDS) is a serious and potentially life-threatening lung condition that can affect children. Currently, ventilator settings commonly used in treatment are based on approaches developed for adults, and it remains unclear whether these settings are equally effective for children. Because children's bodies respond differently than adults', it is important to determine the most effective ventilator strategies specifically for pediatric patients. This study will compare two different ventilator approaches in children with ARDS to identify which method provides the greatest benefit. The findings will also help inform the design of a larger study in the future.
NCT07445061
Acute respiratory distress syndrome (ARDS) is a life-threatening condition with high mortality. Prone position ventilation (PPV) is an evidence-based therapy that improves oxygenation and survival in patients with moderate to severe ARDS; however, outcomes remain heterogeneous. Early identification of patients at high risk of mortality after PPV may improve clinical decision-making and individualized management. This retrospective observational study aims to develop and validate a machine learning model to predict intensive care unit (ICU) mortality in ARDS patients receiving prone position ventilation. Clinical, laboratory, and treatment variables collected from ICU electronic medical records will be used to construct prediction models using multiple machine learning algorithms. The performance of these models will be evaluated and compared to identify the optimal model for mortality prediction.
NCT07414056
The aim of this study is to evaluate the role of Neutrophil-to-Lymphocyte and Platelet-to-Lymphocyte Ratios as predictors for development of ARDS in pediatric burn patients.

NCT07375849
This randomized controlled trial investigates the effects of prone positioning versus lateral positioning at different angles (30°, 90°, 120°) on pulmonary function improvement in patients with acute respiratory distress syndrome (ARDS). Utilizing electrical impedance tomography (EIT) technology, the study monitors key parameters including ventilation distribution and ventilation-perfusion matching in real time, while integrating respiratory mechanics and blood gas analysis data to comprehensively evaluate the therapeutic efficacy of positional adjustments. The study hypothesizes that high-angle lateral positioning may reduce adverse complications associated with prone positioning while effectively improving oxygenation and pulmonary function. The ultimate objective is to provide a safer and more personalized positional therapy regimen for clinical practice, optimizing ARDS treatment strategies to reduce mortality and enhance patient survival outcomes.
NCT07086755
The objective of this study is to assess the efficacy and safety of vadadustat for treating hospitalized patients with nonintubated Acute Respiratory Distress Syndrome (ARDS) secondary to pathogen-associated lung injury.
NCT07090460
Mechanical ventilation in COPD requires a good interaction Patient-Ventilator without asynchronies in order to reduce mortality. Dynamic hyperinflation with PEEPi is responsible for major asynchronies in COPD. It is supposed to be symmetrical between the 2 lungs with the same PEEPi. EIT can measure the distribution of tidal ventilation and interlung lung insufflation delay on the impedance time curve of each lung. Moreover, it is possible in intubated COPD patients to assess one lung PEEPi during low flow insufflation with pressure-EIT monitoring. This study aims to measure interlungs insufflation delay under mechanical ventilation in COPD patients
NCT03870009
This study aims to validate a semi-automatized method to quantify cyclic hyperinflation on CT-scan of ARDS patients. The gold standard will be cyclic hyperinflation assessed on the same CT scan, using manual segmentation of the lung.
NCT07133022
This study aimed to evaluate the effectiveness of early prone positioning in improving clinical outcomes among non-intubated patients with Acute Respiratory Distress Syndrome (ARDS). Prone positioning, which involves placing patients on their stomachs, has been shown to improve outcomes in patients on mechanical ventilation. However, limited evidence exists for its use in non-intubated patients. The researchers conducted a quasi-experimental study at Jenin Governmental Hospital in Palestine, involving two groups: one received early prone positioning in addition to standard care, and the other received standard care alone. Key clinical outcomes included respiratory rate, oxygen saturation, need for intubation, length of Intensive Care Unit (ICU) stay, and mortality. This study adds to the growing evidence supporting non-invasive interventions for managing ARDS and may help inform future clinical guidelines in low-resource settings.
NCT07129330
Acute respiratory distress syndrome (ARDS) is a serious lung condition in which fluid builds up in the air sacs, making it hard to breathe and often requiring intensive care. Older adults fare worse because their lung-lining cells lose the ability to heal properly after injury This study will explore two key molecules-RSPO3 and Syndecan-1 (SDC-1)-that normally help alveolar (air-sac) cells regenerate. We will collect small blood samples from ARDS patients and, when patients undergo elective lung surgery, tiny pieces of healthy lung tissue. In the lab, we will also grow three-dimensional "lung organoids" from these samples to see how boosting or blocking RSPO3/SDC-1 affects cell repair Our goals are to: Measure RSPO3/SDC-1 activity alongside inflammatory markers (e.g., IL-6, TNF-α) to understand their roles in age-related repair failure. Build an integrated platform for early diagnosis, disease monitoring, and treatment evaluation in older ARDS patients. Identify molecular targets that could lead to new therapies, helping older adults recover lung function more effectively.
NCT04009330
Patients prospectively classified to the hyper-inflammatory ARDS phenotype on the basis of clinical characteristics and a novel POC biomarker assay will have worse clinical outcomes than the hypo-inflammatory phenotype. Study Aim The purpose of this project is to prospectively identify hyper- and hypo-inflammatory phenotypes in patients with ARDS and determine clinical outcomes associated with each phenotype. The primary objective of this study is to assess the clinical outcomes in patients with ARDS according to their prospectively defined inflammatory phenotype determined using a POC assay. Results of group allocation will be blinded to clinical and research staff until database lock. Secondary Objectives The secondary objectives of this study are to: (i) Assess the agreement of the phenotype allocation using the POC assay and the clinical study dataset. (ii) Assess the stability of phenotype allocation over time (iii) To test feasibility of delivering a POC assay in the NHS intensive care setting.
NCT06844617
Proning is a way of helping people who are very sick and have trouble breathing. It involves lying patients on their front to get more oxygen into their body. This process happens in a part of the hospital called the Intensive Care Unit, and can last up to 16 hours per day. When in this position, doctors need to turn the patients' head and move their arms every 2-4 hours. Doctors call this repositioning. It helps prevent sores as well as other injuries. To do this, the health care team slide the patient up the bed, so that their (supported) head hangs over the end of the mattress. The head is then turned before the patient is slid back down the bed; their arms are then moved into a different position. This is currently performed by a team of 5+ staff and takes lots of time and resources. The process is also potentially dangerous because it requires a lot of movement which can hurt patients or staff. To make repositioning easier and safer, a group of doctors and engineers have created a new device. It is like a cushion that goes under the patient and inflates. This allows staff to reposition patients without needing to slide the patient on the bed. This also reduces the number of staff needed and lowers the risk to patients and staff. Feedback from staff, patients and the public are being used to help improve the system. To see if the new device works well in other hospitals, the investigators are planning to do a study with 30 patients in up to 4 different hospitals. This will last 14 months, and they will collect information on how well it performs. They will ask patients if they want to take part and will collect feedback after they leave hospital. During the study, staff from each hospital will monitor the device to make sure it is safe and record how useful it is. Any problems will be recorded, and staff will be asked for their opinions on how it affects their work. As well as monitoring safety, they will record the time saving achieved. This is important as it allows repositioning more often, which may reduce pressure sores. It also allows staff to spend more time focusing on other patients and important tasks. To share the results with other doctors, the researchers will write reports and give presentations. If successful, they will start making and selling the device to help sick patients on Intensive Care.

The RECRUIT study is a multinational, multicenter physiological observational study conducted by the PLUG working group. It is a single-day study (1.5-2 hours) associated with specific lung (de)recruitment maneuvers to verify the feasibility of measuring the potential for lung recruitment in mechanically ventilated patients with ARDS by electrical impedance tomography (EIT).
NCT06967207
This multicenter, prospective, observational study aims to develop and validate an EIT-based prognostic model for ARDS. By focusing on the pathophysiological characteristics of ARDS and the causes of ventilator-induced lung injury, the investigators intend to establish a prognostic model that reveals lung injury and heterogeneity, enabling risk stratification and guiding individualized treatment.
NCT06938217
The current standard of care (SOC) for treatment of patients with acute respiratory distress syndrome (ARDS), inhalation injury, volume overload, and/or pulmonary dysfunction is mechanical ventilation (MV). However, these techniques are associated with several complications after prolonged use, including risk of infection, increased sedation requirements, pulmonary edema, ventilator-induced lung injury (VILI), barotrauma, and multi-organ failure. Extracorporeal life support (ECLS) has been used to successfully minimize, replace, or avoid the use of MV. This concept is critical as it permits ultra-lung protective MV settings, mobilization, early ambulation of patients, and timely extubation (when appropriate). Conventional ECLS typically requires blood flows of 3-6 L/min, and its cannula sizes range from 21-25 Fr. This is by definition "high-flow" as it constitutes near-complete extracorporeal circulation of patient's circulating blood volume. On the other hand, low-flow ECLS at 1-2.5 L/min has been shown to prevent deleterious shifts in pH and PaCO2 at a lower level of invasiveness, and its cannula sizes range from 19-20 Fr dual lumen cannulas (which are associated with less serial dilation). The investigators propose the use of a low-flow circuit to include the NovaLung system in conjunction with a smaller tubing set and cannula to enable earlier utilization of ECLS with less invasiveness and smaller catheters. Specifically, the study will either utilize the Crescent RA cannula (or equivalent dual-lumen cannula) or use a 15-25 Fr cannula, both with 3/8 tubing/step-down tubing, as needed, for our study. A femoral (fem)-femoral or femoral-internal jugular (IJ) approach may also be used. Carbon dioxide is six times more diffusible than oxygen across the membrane; thus, carbon dioxide transfers can occur with high efficiency at our targeted blood flows of 1-2.5L/min. Oxygen can still transfer at these blood flows, and low flow can improve oxygen levels to some degree. There are three benchtop-based manuscripts that suggest that low-flow ECMO is associated with a potential increase in factors that increase the risk of bleeding complications/circuit changes. However, the manuscripts either tested \<1 L/min blood flow rates, or the effect of cannula size was not considered. None of them included the biological component of endothelial interaction. Mitigating the risk of bleeding complications by will be completed by administering anticoagulants with a target PTT of 40-50 seconds, and by monitoring the patients and their coagulation panels closely. There may be less risk of circuit clotting in our study because of chosen flow rates (1-2.5 L/min).

NCT05137795
Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
