Filter by:Single blind randomized clinical trial designed to evaluate the efficacy of the combination of hydroxychloroquine and dexamethasone as treatment for severe Acute Respiratory Distress Syndrome (ARDS) related to coronavirus disease 19 (COVID-19). We hypothesize that dexamethasone (20 mg for 5 days followed by 10 mg for 5 days) combined with 600 mg per day dose of hydroxychloroquine for 10 days will reduce the 28-day mortality compared to hydroxychloroquine alone in patients with severe ARDS related COVID-19.
The clinical study with UMC119-06 is designed to investigate the safety in patients with moderate acute respiratory distress syndrome ("ARDS"). This will be a dose escalation, open-label, single-center study in adult with ARDS. UMC119-06 is ex vivo cultured human umbilical cord derived mensenchymal stem cells (hUC-MSCs) product which is intended for treatment of ARDS.
This study intended to evaluate the effects of commonly used diuretic, spironolactone, on oxygenation in covid-19 ARDS patients.
***At this time, we are only enrolling at Houston Methodist Hospital (HMH)/Baylor College of Medicine (BCM) and are not shipping cells outside of BCM/HMH.*** This is a study for patients who have respiratory infection caused by SARS-CoV-2 that have not gotten better. Because there is no standard treatment for this infection, patients are being asked to volunteer for a gene transfer research study using mesenchymal stem cells (MSCs). Stem cells are cells that do not yet have a specific function in the body. Mesenchymal stem cells (MSCs) are a type of stem cell that can be grown from bone marrow (the spongy tissue inside of bones). Stem cells can develop into other types of more mature (specific) cells, such as blood and muscle cells. The purpose of this study is to see if MSCs versus controls can help to treat respiratory infections caused by SARS-CoV-2.
This study will evaluate the safety of a 96-hour intravenous vitamin C infusion protocol (50 mg/kg every 6 hours) in patients with hypoxemia and suspected COVID-19.
The outbreak of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been declared a public health emergency of international concern. Hospitalized COVID-19-positive patients requiring ICU care is increasing along with the course of epidemic. A large number of these patients developed acute respiratory distress syndrome (ARDS) according to current data. However, the related hemodynamic characteristic has so far been rarely described.
The actual pandemic infection related to SARS-CoV2 results in viral pneumonitis (COVID-19), that may, in the more severe cases, lead the patients to the intensive care unit (ICU). The more frequent presentation is acute respiratory distress syndrome (ARDS). To penetrate cells, SARS-CoV2 uses Angioconvertase type 2 (ACE2) as a cellular entry receptor. ACE2 belong to the renin-angiotensin-aldosteron system (SRAA), and ACE2 levels are directly modified when SRAA inhibitors are administred to patients, and ACE2 level increases particularely with Angiotensin II Receptor blockers (ARA2) use. The aim of our study is to determine ACE2 level and activity in patients with SARSCoV2 infection admitted to the intensive care unit (ICU). COVID ARA2 is a propsective cohort of patient with blood sampling at the day of admission, day 3 and day 7.
Rationale: The current SARS-CoV-2 pandemic has a high burden of morbidity and mortality due to development of the so-called acute respiratory distress syndrome (ARDS). The renin-angiotensin-system (RAS) plays an important role in the development of ARDS. ACE2 is one of the enzymes involved in the RAS cascade. Virus spike protein binds to ACE2 to form a complex suitable for cellular internalization. The downregulation of ACE2 results in the excessive accumulation of angiotensin II, and it has been demonstrated that the stimulation of the angiotensin II type 1a receptor (AT1R) increases pulmonary vascular permeability, explaining the increased lung pathology when activity of ACE2 is decreased. Currently available AT1R blockers (ARBs) such as valsartan, have the potential to block this pathological process mediated by angiotensin II. There are presently two complementary mechanisms suggested: 1) ARBs block the excessive angiotensin-mediated AT1R activation, and 2) they upregulate ACE2, which reduces angiotensin II concentrations and increases the production of the protective vasodilator angiotensin 1-7. In light of the above, ARBs may prevent the development of ARDS and avert morbidity (admission to intensive care unit (ICU) and mechanical ventilation) and mortality. Objective: To investigate the effect of the ARB valsartan in comparison to placebo on the occurrence of one of the following items, within 14 days of randomization:1) ICU admission; 2) Mechanical ventilation; 3) Death. Study design: A double-blind, placebo-controlled 1:1 randomized clinical trial Study population: Adult hospitalized SARS-CoV-2-infected patients (n=651). Intervention: The active-treatment arm will receive valsartan in a dosage titrated to blood pressure up to a maximum of 160mg b.i.d. and the placebo arm will receive a matching placebo also titrated to blood pressure. Treatment duration will be 14 days or up to hospital discharge < 14 days or occurrence of the primary endpoint if < 14 days. Main study endpoint: The primary study endpoint is the occurrence within 14 days of randomization of either: 1) ICU admission; 2) Mechanical ventilation; 3) Death.
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.
