Filter by:There is an urgent need to understand the outcomes of COVID-19 infected patients who undergo surgery, specially vascular surgery. Capturing real-world data and sharing Spanish national experience will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, improving their clinical care. The global community has recognised that rapid dissemination and completion of studies in COVID-19 infected patients is a high priority, so we encourage all stakeholders (local investigators, ethics committees, IRBs) to work as quickly as possible to approve this project. This investigator-led, non-commercial, non-interventional study is extremely low risk, or even zero risk. This study does not collect any patient identifiable information (including no dates) and data will not be analysed at hospital-level.
19 COVID (Coronavirus disease 2019 ) is a deadly viral disease that has been spreading around the world for several months, and is caused by a CORONA family virus (COVID-19). Following IN-VITRO evidence of the antiviral effect of CHLOROQUINE in CORONA viruses, this drug has been used empirically for COVID-19 patients and is currently recommended in Israel for the treatment of intermediate and severity disease. The mechanism of action of chloroquine is in part by inhibiting the virus distribution, and changing the intracellular acidity, the virus distribution site. The intracellular chloroquine concentration is determined by a pump called PGP (permeability glycoprotein) that removes the drug from the cell and is activated by the drug. In the treatment of malaria, the benefit of low dosage of the drug has been shown to be effective due to the fact that the intracellular concentration of the drug is probably higher, and therefore the logic to examine this issue in COVID-19 treatment. The purpose of this study is to test whether a low dose of Chloroquine will reduce the duration of the viral shedding and prevent the disease from worsening.
To investigate the mechanism, clinical outcome and therapeutic efficacy with favipiravir of Corona Virus Disease 2019 patients whose nucleic acids changed from negative to positive.
In this study, defined cases of COVID-19 with mild, moderate or severe pneumonia will be treated with standard treatment regimens in combination with IV injection of Deferoxamine. Improvement in clinical, laboratory and radiological manifestations will be evaluated in treated patient compared to control group.
Patients with documented moderate COVID-19 infection will be randomized 1:1 to receive piclidenoson 2 mg Q12H orally with standard supportive care (SSC - intervention arm) or placebo orally with SSC (control arm) for up to 28 days.
Phase II & Phase III: This is a pragmatic, adaptive, randomized, multicenter phase II/III study evaluating IFX-1 for the treatment of COVID-19 related severe pneumonia. The study consists of two parts: Phase II, an open-label, randomized, 2-arm phase evaluating best supportive care (BSC) + IFX-1 (Arm A) and BSC alone (Arm B); and Phase III, a double-blind, placebo-controlled, randomized phase comparing standard of care (SOC) + IFX-1 (Arm A) versus SOC + placebo-to-match (Arm B)
The outbreak of a novel coronavirus (SARS-CoV-2) and associated COVID-19 disease in late December 2019 has led to a global pandemic. At the time of writing, there have been 150 000 confirmed cases and 3500 deaths. Apart from the morbidity and mortality directly related to COVID-19 cases, society has had to also cope with complex political and economic repercussions of this disease. At present, and despite pressing need for therapeutic intervention, management of patients with COVID-19 is entirely supportive. Despite the majority of patients experiencing a mild respiratory illness a subgroup, and in particular those with pre-existing cardiovascular disease, will experience severe illness that requires invasive cardiorespiratory support in the intensive care unit. Furthermore, the severity of COVID-19 disease (as well as the likelihood of progressing to severe disease) appears to be in part driven by direct injury to the cardiovascular system. Analysis of data from two recent studies confirms a significantly higher likelihood of acute cardiac injury in patients who have to be admitted to intensive care for the management of COVID-19 disease. The exact type of acute of cardiac injury that COVID-19 patients suffer remains unclear. There is however mounting evidence that heart attack like events are responsible. Tests ordinarily performed to definitely assess for heart attacks will not be possible in very sick COVID-19 patients. Randomising patients to cardioprotective medicines will help us understand the role of the cardiovascular system in COVID-19 disease. It will also help us determine if there is more we can do to treat these patients.
Whereas the pandemic due do Covid-19 continues to spread, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes Severe Acute Respiratory Distress Syndrome in 30% of patients with a 30%-60% mortality rate for those requiring hospitalization in an intensive care unit. The main physio-pathological hallmark is an acute pulmonary inflammation. Currently, there is no treatment. Mesenchymal stem cells (MSC) feature several attractive characteristics: ease of procurement, high proliferation potential, capacity to home to inflammatory sites, anti-inflammatory, anti-fibrotic and immunomodulatory properties. If all MSC share several characteristics regardless of the tissue source, the highest productions of bioactive molecules and the strongest immunomodulatory properties are yielded by those from the Wharton's jelly of the umbilical cord. An additional advantage is that they can be scaled-up to generate banks of cryofrozen and thus readily available products. These cells have already been tested in several clinical trials with an excellent safety record. The objective of this project is to treat intubated-ventilated patients presenting with a SARS-CoV2-related Acute Respiratory Distress Syndrome (ARDS) of less than 96 hours by three intravenous infusions of umbilical cord Wharton's jelly-derived mesenchymal stromal cells (UC-MSC) one every other day (duration of the treatment: one week). The primary endpoint is the PaO2/FiO2 ratio at day 7. The evolution of several inflammatory markers, T regulatory lymphocytes and donor-specific antibodies will also be monitored. The trial will include 40 patients, of whom 20 will be cell-treated while the remaining 20 patients will be injected with a placebo solution in addition to the standard of care. Given the pathophysiology of SARS-CoV2, it is thus sound to hypothesize that the intravenous administration of UC-MSC during the initial phase of ARDS could control inflammation, accelerate its recovery with improved oxygenation, reduced mechanical ventilation and ventilation weaning time and therefore reduced length of stay in intensive care. The feasibility of the project is supported by the expertise of the Meary Cell and Gene Therapy Center, which is approved for the production of Advanced Therapy Medicinal Products and has already successfully prepared the first batches of cells, as well as by the involvement of a cardiac surgery team which will leverage its experience with stem cells for the treatment of heart failure to make it relevant to the Stroma-Cov-2 project.
There is currently no specific vaccine or treatment to treat critically ill patients with COVID-19. Different therapies are still under investigation and are use in different health institutions, however, a significant proportion of patients do not respond to these treatments, so it is important to seek new treatments. One of these alternatives is the use of convalescent plasma. The investigator will use plasma obtained from convalescent individuals with proven novel SARS-CoV-2 virus infection, diagnosed with coronavirus-19-induced disease and symptom-free for a period of not less than 10 days since they recovered from the disease. This plasma will be infused in patients affected by the same virus, but who have developed respiratory complications that have not responded favorably to usual treatment such as chloroquine, hydroxychloroquine, azithromycin, and other antivirals. The investigator will evaluate the safety of this procedure by accounting for any adverse event.
In order to assess the efficacy of hydroxychloroquine treatment weekly for a total of 7 weeks in the prevention of COVID-19 infection, three hundred sixty (360) Healthcare workers with high risk exposure to patients infected with COVID-19 will be tested for COVID-19 infection via nasopharyngeal (NP) swab once weekly for 7 weeks. Of those, one hundred eighty (180) will receive weekly doses of hydroxychloroquine for the duration of the study. Subjects who opt not to receive the study drug will form the control group.
