New Lung Ventilation Strategies Guided by Transpulmonary Pressure in VV-ECMO for Severe ARDS
Respiratory Distress SyndromeAdultExtracorporeal membrane oxygenation (ECMO) has been widely used in patients with severe acute respiratory distress syndrome (ARDS). But how to choose mechanical ventilation strategy is still not clear for severe ARDS patients supported by ECMO. Our previous work found that, compared to the traditional "lung rest" strategy, transpulmonary pressure guide new lung ventilation strategy can better maintain lung volume reduction lung collapse, atelectasis occurs. The severe ARDS patients receiving ECMO therapy were randomized divided into a new ventilation strategy group and the conventional ventilation strategy group. The new ventilation strategy is transpulmonary pressure guide ventilator setting method, and the conventional ventilation strategy is Extracorporeal Life Support Organization (ELSO) guide ventilation method. Compare the difference between the two groups of patients in lung injury, and explore the lung protection mechanism of new lung ventilation strategies guided by transpulmonary pressure. Our research group considered that transpulmonary pressure guide new lung ventilation strategy can provide more effective lung protection. And it will be further used in clinical work.
A Double Blind, Randomized, Controlled Study to Evaluate CHF 5633 (Synthetic Surfactant) and Poractant...
Respiratory Distress SyndromeNewbornA multicenter, double blind, randomized, single dose, active-controlled study to investigate the efficacy and safety of synthetic surfactant (CHF 5633) in comparison to porcine surfactant (Poractant alfa, Curosurf ®) in the treatment of preterm neonates with respiratory distress syndrome. Main objectives of this study are to investigate the short term efficacy profile of CHF 5633 vs. porcine surfactant (Poractant Alfa, Curosurf®) in terms of reduced oxygen requirement and ventilatory support and to evaluate the mid-term efficacy profile in terms of reduced incidence of bronchopulmonary dysplasia (BPD) and mortality/BPD rate at 36 weeks post menstrual age (PMA), mortality rate at 28 days and 36 weeks PMA, RDS-associated mortality through 14 days of age and other major co-morbidities of prematurity. Inclusion criteria are: Written parental informed consent, inborn preterm neonates of either sex with a gestational age of 24+0 weeks up to 29+6 weeks, clinical course consistent with RDS, requirement of endotracheal surfactant administration within 24 hours from birth, fraction of inspired oxygen (FiO2) ≥0.30 for babies 24+0 to 26+6 weeks and FiO2 ≥0.35 for babies 27+0 to 29+6 weeks to maintain arterial oxygen saturation by pulse oximetry (SpO2) between 88-95%.

Mesenchymal Stem Cells (MSCs) for Treatment of Acute Respiratory Distress Syndrome (ARD) in Patients...
Blood And Marrow TransplantationAdult Respiratory Distress SyndromeThe goal of this clinical research study is to learn about the safety of giving mesenchymal stem cells (MSCs) to patients who have ARDS. Researchers also want to learn if these cells can help control ARDS when given with drugs that are routinely used to treat ARDS. In this study, participants will receive 1 infusion of MSCs. This is an investigational study. MSC infusions for the treatment of ARDS is investigational. Up to 20 patients will take part in this study. All will be enrolled at MD Anderson.
Aerosolized Surfactant in Neonatal RDS
Respiratory Distress SyndromeNewbornRespiratory distress syndrome (RDS), caused by surfactant deficiency, is the leading cause of mortality and morbidity in preterm infants. Intratracheal instillation, the only approved means of surfactant delivery, requires endotracheal intubation and mechanical ventilation with their attendant risks. Interventions that decrease need for intubation and mechanical ventilation like noninvasive ventilation (NIV) including nasal continuous positive airway pressure, high flow nasal cannula or nasal intermittent mandatory ventilation are increasingly being used for initial respiratory support in preterm neonates with RDS to improve outcomes. Aerosolized surfactant delivered during NIV is an innovative and promising concept for the treatment of RDS - retaining the advantages of early surfactant with alveolar recruitment while obviating the risks of intubation and mechanical ventilation. The investigators overall hypothesis is that treatment of RDS with aerosolized surfactant in preterm infants undergoing NIV is safe and feasible and will result in short-term improvement in oxygenation and ventilation. The objective of this proposal is to perform a single-center unblinded Phase II randomized clinical trial of aerosolized surfactant for the treatment of RDS in preterm neonates undergoing NIV.

Diaphragm Electrical Activity of Preterm Infants on nCPAP Versus NIHFV
Respiratory Distress SyndromeNewbornPreterm babies have immature lungs and frequent pauses in their breathing which often necessitates breathing support. Nasal Continuous Positive Airway Pressure (nCPAP) is one of the most commonly used tools, but does not always provide enough support. A new option is non-invasive high frequency ventilation (NIHFV), which gently shakes the lungs to help with gas exchange and may decrease a baby's work of breathing. The investigators plan to study very low birth weight preterm babies who are generally well but require some support with their breathing. By inserting a special feeding tube with sensors into the stomach, the investigators can measure the electrical activity of the diaphragm (EAdi), which is an important muscle for breathing. By analyzing EAdi in babies receiving either nCPAP or NIHFV, the investigators will be able to measure and compare how each method of support affects a baby's breathing. This important study will help us determine the most appropriate breathing support for preterm babies.
Chest Physiotherapy in Tracheotomized Patients
Acute Respiratory Distress SyndromePositive expiratory pressure (PEP) breathing is common for treatment of different lung diseases and can increase lung volume and increase elimination of secretion from the airways. Today there is no evidence whether the treatment is effective or not for patients in the intensive care unit. The purpose of this study is to evaluate if PEP breathing can increase oxygenation for patients in the intensive care unit during weaning from the ventilator after acute respiratory distress syndrome. PEP breathing will be applied on the tracheal cannula for 15 minutes. Measure of the PEP effect will be done before, during and for 20 minutes after PEP breathing.
Prone Position in Patients on High-flow Nasal Oxygen Therapy for COVID-19 (HIGH-PRONE-COVID-19)...
Acute Respiratory Distress SyndromeCOVID-19Acute Respiratory Distress Syndrome (ARDS) induces high mortality, particularly in the context of COVID-19 disease. Preliminary data from patients with ARDS related to COVID-19 disease appear to show significant effectiveness of prone positioning in intubated patients in terms of oxygenation as well as nasal high flow therapy before intubation. It should be noted that in Jiangsu province, secondarily affected, nasal high flow combined with the prone position was successfully integrated into care protocols. The investigators hypothesize that the combined application of nasal high flow and prone positioning can significantly improve the outcome of patients suffering from COVID-19 pneumonia by reducing the need for tracheal intubation and associated therapeutics such as sedation and paralysis, resulting in both individual and collective benefits in terms of use of scarce critical care resources. Investigators hypothesize that the combined application of nasal high-flow and prone positioning can significantly improve the outcome of patients suffering from COVID-19 pneumonia by reducing the need for intubation and associated therapeutics such as sedation and paralysis, resulting in both individual and collective benefits in terms of use of scarce critical care resources.
A Study of APL-9 in Adults With Mild to Moderate ARDS Due to COVID-19
COVIDCovid-197 moreThe purpose of this study is to evaluate the safety and effectiveness of APL-9 in adults with mild to moderate ARDS (acute respiratory distress syndrome) caused by COVID-19 who are hospitalized and require supplemental oxygen therapy with or without mechanical ventilation. It is thought that COVID-19 activates the complement system, part of the immune system that responds to infection or tissue damage, and increases inflammation in the lungs. APL-9 has been designed to inhibit or block activation of part of the complement pathway, and potentially reduce inflammation in the lungs. Part 1 of the study is open-label to evaluate safety; all participants will receive APL-9 plus standard of care. Part 2 of the study is double-blind, randomized; participants will receive either APL-9 or the vehicle-control plus standard of care.
Cellular Immuno-Therapy for COVID-19 Acute Respiratory Distress Syndrome
Acute Respiratory Distress SyndromeCovid19The clinical picture of the novel corona virus 2 (SARS-CoV-2) disease (COVID-19) is rapidly evolving. Although infections may be mild, up to 25% of all patients admitted to hospital require admission to the intensive care unit, and as many as 40% will progress to develop severe problems breathing due to the acute respiratory distress syndrome (ARDS). ARDS often requires mechanical ventilation, with a 50% risk of mortality. Researchers at the Ottawa Hospital Research Institute (OHRI) have been studying the potential therapeutic role of mesenchymal stromal/stem cells, or MSCs, for the treatment of ARDS for over a decade. This has led to the world's first clinical trial using MSC therapy for patients with severe infections (sepsis) which is often associated with ARDS (NCT02421484). This trial demonstrated tolerability, and potential signs of efficacy. In addition, the investigators have established expertise in producing clinical-grade MSCs and have received approval from Health Canada for the use of MSCs in three different clinical studies. This protocol consists of 2 sequential trials using the same trial infrastructure, noted as the Phase 1 trial 'CIRCA-1901' and the Phase 2a trial 'CIRCA-1902'. CIRCA-1901 is an open-label, dose-escalating and safety trial using a 3+3+3 design to determine the safety, and maximum feasible tolerated dose of repeated delivery of Umbilical Cord Mesenchymal Stromal Cells (UC-MSC) intravenously. The investigators will enroll up to 9 patients; each receiving repeated unit doses of UC-MSCs delivered by IV infusion on each of 3 consecutive days (24±4 hours apart) according to the following dose-escalation schedule (3 patients per dose panel): (i) Panel 1: 25 million cells/unit dose (cumulative dose: 75 million MSCs), (ii) Panel 2: 50 million cells/unit dose (cumulative dose: 150 million MSCs), (iii) Panel 3: up to 90 million cells/unit dose (cumulative dose: up to 270 million MSCs). If no safety issues are identified, we will continue to the Phase 2a trial. CIRCA-1902 is a single-arm, open-label extension of the CIRCA-1901 trial to assess early signs of efficacy (major morbidity and mortality). The Phase 2a trial (CIRCA-1902) will enroll 12 patients to assess early signals of benefit on mortality and major morbidity in a high risk, high mortality population.
