Filter by:Patients presenting to the emergency department, or needing hospitalization, for a variety of medical conditions often require non-invasive ventilation (breathing support). For example, for a person with shortness of breath as a complication of COPD (Chronic obstructive pulmonary disease) the gold standard of care requires application of a BiPAP machine. However, in the current environment of COVID-19, the aerosols produced by this machine in a COVID-19 positive patient pose serious potential harms to healthcare providers and other patients. All patients with similar symptoms to COVID-19 need to be treated as positive until definite testing determines otherwise. The best test available for COVID-19 takes up to 4 hours to determine the patients status, which is too long to delay application of a BiPAP. This could lead to either a delay in care or the need for invasive breathing measures (intubation), which requires intense resource utilization, may not be in line with a patient's goals of care, and could cause serious harms (i.e. infection, medication reactions, etc.) in patients who do not need it. The use of a closed-loop BiPAP machine in which no expired air is released into the environment would solve these problems. Building off the failures of a similar approach that was trialed in Italy in response to the COVID-19 crisis, this project will develop and test a novel closed-loop BiPAP system.
This registry will evaluate the impact of the COVID19 outbreak on Cardiac patients admitted in the Intensive Care Unit of the Pitie-Salpetriere Hospital in Paris, France
Bevacizumab, ZERIBEV® (Pfizer)/AVASTIN® (Roche) 25 mg/ml ®, is a recombinant humanised monoclonal IgG1 antibody It seems interesting to use bevacizumab in severe patients infected with SARS-CoV-2 requiring hospitalization in conventional unit or in ICU. This protocol CORIMUNO19-BEVA will evaluate the efficacy and safety of AVASTIN®/ ZERIBEV® (bevacizumab) COVID-19 patients hospitalized in conventional units. This phase 2 randomized clinical trial aimed at evaluating the efficacy and safety of AVASTIN®/ ZERIBEV® (bevacizumab) alone versus standard of care (SoC) in patients hospitalized in conventional units.
COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. There is currently no vaccine to prevent Covid-19 or infection with SARS-CoV-2 or therapeutic agent to treat COVID-19. This protocol CORIMUNO19-COAG will evaluate the efficacy and safety of active anticoagulation using heparin: Tinzaparin (INNOHEP®) or unfractionated heparin (Calciparine®, Héparine Sodique Choay®) in COVID-19 patients hospitalized in conventional or intensive care units. It will use a phase 2 randomized open-label multicentre clinical trial, where patients will be randomly allocated to anticoagulation versus Standard of Care.
The main manifestation of COVID-19 is acute hypoxemic respiratory failure (AHRF). In patients with AHRF, the need for invasive mechanical ventilation is associated with high mortality. Two hypotheses will be tested in this study. The first hypothesis is the benefit of corticosteroid therapy on severe COVID-19 infection admitted in ICU in terms of survival. The second hypothesis is that, in the subset of patients free of mechanical ventilation at admission, either Continuous Positive Airway Pressure (CPAP) or High-Flow Nasal Oxygen (HFNO) allows to reduce intubation rate safely during COVID-19 related acute hypoxemic respiratory failure.
The Post discharge after surgery Virtual Care with Remote Automated Monitoring technology (PVC-RAM) Trial is a multicentre, parallel group, superiority, randomized controlled trial to determine the effect of virtual care with remote automated monitoring (RAM) technology compared to standard care on days alive at home during the 30-day follow-up after randomization, in adults who have undergone semi-urgent (e.g., oncology), urgent (e.g., hip fracture), or emergency (e.g., ruptured abdominal aortic aneurysm) surgery. It will also determine, during the first 30 days, the effect of virtual care with RAM technology on several secondary outcomes, including: 1. hospital re-admission; 2. emergency department visit; 3. urgent-care centre visit; 4. acute-hospital care (i.e., a composite of hospital re-admission and emergency department or urgent-care centre visit) 5. brief acute-hospital care (i.e., acute-hospital care that lasts <24 hours); 6. all-cause hospital days; 7. medication error detection; 8. medication error correction; and 9. death. An additional secondary objective is to determine the effect of virtual care with RAM technology on pain at 7, 15, and 30 days and 6 months after randomization.
This is a phase 2b prospective, randomized, single-blind, controlled trial of a single subcutaneous injection of peginterferon lambda-1a versus placebo for prevention of SARS-CoV-2 infection in non-hospitalized participants at high risk for infection due to household exposure to an individual with coronavirus disease (COVID-19). The study will also evaluate the regimens participants with asymptomatic SARS-CoV-2 infection detected at study entry. All participants will be followed for up to 12 weeks.
Prone positioning is a well studied and validated treatment for severe acute respiratory distress syndrome (ARDS), however there are no randomized studies on the use of prone positioning in the non-intubated patient. It is unknown if this intervention would be helpful in preventing further respiratory deterioration in terms of increasing supplemental oxygen requirements, endotracheal intubation, and ICU admission. The Awake Prone Position for Early hypoxemia in COVID-19 (APPEX-19) Study is a pragmatic adaptive randomized controlled unblinded trial. APPEX-19 randomizes non-ICU patients with COVID-19 or who are under evaluation for COVID-19 to lie in a prone position (i.e, with their stomach and chest facing down) or to usual care.
COVID-19 is a respiratory illness caused by SARS-CoV-2 with a range of symptoms from mild, self-limiting respiratory tract infections to severe progressive pneumonia, multiorgan dysfunction and death. A portion of individuals with COVID-19 experience life-threatening hypoxia requiring supplemental oxygen and mechanical ventilation. Management of hypoxia in this population is complicated by contraindication of non-invasive ventilation and limitations in access to mechanical ventilation and critical care staff given the clinical burden of disease. Positional therapy is readily deployable and may ultimately be used to treat COVID-19 related respiratory failure in resources limited settings; and, it has been demonstrated to improve oxygenation and is easy to implement in the clinical setting. The overall goal of this randomized controlled trial is to establish the feasibility of performing a randomized trial using a simple, minimally invasive positional therapy approach to improve hypoxia and reduce progression to mechanical ventilation. The objectives are to examine the effectiveness and feasibility of maintaining an inclined position in patients with confirmed or suspected COVID-19 associated hypoxemic respiratory failure. The investigators hypothesize that (1) oxyhemoglobin saturation will improve with therapy, (2) participants will tolerate and adhere to the intervention, and that (3) participants who adhere to positional therapy will have reduced rates of mechanical ventilation at 72 hours. If successful, this feasibility trial will demonstrate that a simple, readily deployed nocturnal postural maneuver is well tolerated and reverses underlying defects in ventilation and oxygenation due to COVID-19. It will also inform the design of a pivotal Phase III trial with estimates of sample sizes for clinically relevant outcomes.
Immunotherapy based on Adoptive Cellular Transfer (ACT) uses several types of immune cells, including dendritic cells, cytotoxic T lymphocytes, lymphokine-activated killer cells, and NK cells. NK cell-based immunotherapies are an attractive approach for treating diseases because of their characteristic recognition and killing mechanisms; they are involved in the early defense against infectious pathogens and against MHC class-I-negative or -low-expressing targets without the requirement for prior immune sensitization of the host and are able to lyse target through the release of perforin and granzymes and using antibody-dependent cellular cytotoxicity pathways mediated by Fc receptor for IgG (CD16). The aim of this project is to evaluate the safety and immunogenicity of allogeneic NK cells from peripheral blood mononuclear cells (PBMCs) of healthy donors in patients infected with COVID-19 collected by apheresis. This allows us to collect cGMP PBMCs and immunomagnetic remove several types of undesirable cells including B, T and CD33+ cells with enrichment of NK cells that will be expanded in bioreactors with GMP culture media (AIM-V) supplemented with human AB serum and GMP grade IL-2, and IL-15. After quality control verification the final NK cell product will be resuspended in 300 mL saline solution for intravenous infusion. Initially, we will enroll in this study ten COVID-19 infected adult patients with moderate symptoms (NEWS 2 scale score>4). Consent forms will be signed by the patient before the therapy. Patients will be treated with three different infusions of NK cells 48 h apart with 1, 10, and 20 million cells/kg body weight. We will follow the patients for any adverse effect, clinical response and immune effects by flow cytometry including markers for NK cells expressing different markers (CD158b, NKG2A, and IFN-y). We anticipated that the release of IFN-y by exogenous NK cells could attract other immune cell populations to boost the immune response against COVID-19.
