COVID-19 Clinical Trials and Expanded Access

The main objective of this study is to assess the efficacy of the combination hydroxychloroquine and Azithromycin (HCQ and AZ) in reducing the infection risk among health care professionals in direct contact with COVID-19 patients.

Elderly, hypertension, diabetes and cardiovascular diseases are risk factors for COVID-19 morbility and mortality. However, the real reason for this is not yet understood. It is well documented that gut microbiota has a critical role in health, particularly in the immune system and therefore, we propose that gut microbiota composition could affect vulnerability and disease outcomes of COVID-19.

The purpose of this study is to build a large dataset of Computed Tomography (CT) images for identification of accurate CT criteria and development of deep learning-based solutions for diagnosis, quantification and prognostic estimation.

It is a multicenter, randomized, placebo-controlled, double-blind study. The study population is defined as subjects diagnosed with lower respiratory tract COVID-19 who require supplemental oxygen ≥2 LPM at the time of randomization.

The purpose of this study is to collect French medical data for patients with Multiple Sclerosis (MS) or NeuroMyelitis Optica (NMO) spectrum disorder who are diagnosed or strongly suspected of being infected with Covid19. The objective of this study is to provide scientific information regarding the possible risk factors in these patients, as a large part of them receive immunomodulatory or immunosuppressive treatments. The main objective of this study is thus to determine the epidemiological (eg, age, form of disease, disability) and pharmacological (related to immunomodulatory or immunosuppressive treatments) factors favoring the occurrence of a severe form of Covid-19 in MS and NMO patients.

This protocol provides access to eculizumab treatment for participants with severe COVID-19.

CORIA is an observational cohort study of immunosuppressed populations who test positive for COVID-19. This includes people living with HIV, cancer, acquired immunodeficiency associated with other immunosuppressive therapy, primary immunodeficiency and recipients of a solid organ transplant. Participants will have routine clinical data collected with optional baseline collection and storage of a blood sample for storage . The study will be conducted in up to 30 sites within Australia.

The purpose of this research study is to learn about the safety and efficacy of human umbilical cord derived Mesenchymal Stem Cells (UC-MSC) for treatment of COVID-19 Patients with Severe Complications of Acute Lung Injury/Acute Respiratory Distress Syndrome (ALI/ARDS).

In late 2019, a new coronavirus emerged in Wuhan Province, China, causing lung complications similar to those produced by the SARS coronavirus in the 2002-2003 epidemic. This new disease was named COVID-19 and the causative virus SARS-CoV-2. The SARS-CoV-2 virus, enters the airway and binds, by means of the S protein on its surface to the membrane protein ACE2 in type 2 alveolar cells. The S protein-ACE2 complex is internalized by endocytosis leading to a partial decrease or total loss of the enzymatic function ACE2 in the alveolar cells and in turn increasing the tissue concentration of pro-inflammatory angiotensin II by decreasing its degradation and reducing the concentration of its physiological antagonist angiotensin 1-7. High levels of angiotensin II on the lung interstitium can promote apoptosis initiating an inflammatory process with release of proinflammatory cytokines, establishing a self-powered cascade, leading eventually to ARDS. It has recently been proposed the tentative use of agents such as losartan and telmisartan as alternative options for treating COVID-19 patients prior to development of ARDS. The present study is an open-label randomized phase II clinical trial for the evaluation of telmisartan in COVID-19 patients. Briefly, patients with confirmed diagnosis of SARS-CoV-2, will be randomized to receive 80 mg/12h of telmisartan plus standard care or standard care alone aand will be monitored for development of systemic inflammation and acute respiratory distress syndrome. Other variables regarding lung function and cardiovascular function will also be evaluated.

Novel coronavirus disease (COVID-19) is a newly discovered contagious disease caused by SARS-CoV-2 virus, primarily manifesting as an acute respiratory illness with pneumonia, but can affect multiple organs such as kidney, heart, digestive tract, blood and nervous system. In previous reports of SARS and MERS-CoV infections, acute kidney injury was described in 5 to 15% of patients and was associated with a high mortality rate (60-90%). Recent reports showed renal abnormalities in COVID-9 infected patients. A recent Chinese study also reported that acute kidney injury was an independent risk factor for mortality. However, the exact mechanism of kidney involvement remains unclear: sepsis-related cytokine storm or direct cellular injury from the virus. Also, kidney involvement has not yet been well characterized: heavy albuminuria, hematuria or interstitial nephropathy alone. A recent study identified viral RNA in kidney tissue and another study succeeded isolating SARS-CoV-2 from the urine sample of an infected patient. These data suggest that the kidney might be a target of this novel coronarivus. The sponsor suggests characterizing kidney involvement in SARS-CoV-2 infection. Study objectives are: - To give an accurate characterization of kidney involvement in COVID-19 - To investigate the physiopathologic mechanism of kidney involvement in SARS-CoV-2 infection - To identify risk factors for kidney involvement in in SARS-CoV-2 infection - To evaluate the impact of kidney involvement in in SARS-CoV-2 infection - To assess the long-term health effect of kidney injury on survivors of in SARS-CoV-2 infection
