COVID-19 Clinical Trials and Expanded Access

The 2019 novel-coronavirus (2019-nCov) is the cause of a cluster of unexplained pneumonia that started in Hubei province in China. It has manifest into a global health crisis with escalating confirmed cases and spread across many countries. In view of the fact that there is currently no effective antiviral therapy, the prevention or treatment of diseases caused by COVID-19 can be tough for current treatment. This study is a phase I clinical trial. The investigators intent to evaluate the safety, reactogenicity and immunogenicity of Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector) .

This project aims to use artificial intelligence (image discrimination) algorithms, specifically convolutional neural networks (CNNs) for scanning chest radiographs in the emergency department (triage) in patients with suspected respiratory symptoms (fever, cough, myalgia) of coronavirus infection COVID 19. The objective is to create and validate a software solution that discriminates on the basis of the chest x-ray between Covid-19 pneumonitis and influenza

All patients with COVID-19 were divided into three groups according to their illness: mild patient who receive conventional oxygen therapy, severe patients who receive nasal high flow oxygen inhalation or non-invasive positive pressure ventilation，all the oxygen therapy will be used as part of the standard of care. Each group will enroll 10 patients, the treatment of all patients will be continuously optimized during observation, and the incidence of respiratory failure, intubation rate, 28 day mortality rate, ICU hospitalization days, etc will be recorded and analyzed so to optimize the treatment time window of sequential oxygen therapy

Our project intends to independently develop a fully enclosed rapid detection system for a total of 22 pathogens, including SARS-CoV-2, on the basis of the QIAstat-Dx fully automatic multiple PCR detection platform. The reasonably designed experiments are used to verify the performance of the cartridge detection and prove its clinical application value. The 22 pathogens tested in this project includes 4 coronavirus subtypes, A / B flu, parainfluenza virus, respiratory syncytial virus, etc., which is of great significance for the differential diagnosis of similar patients.

The acute lung injury caused by SARS and 2003 were both related to the inflammatory cytokine storm in patients. The biochemical test showed abnormal increase in related indicators such as interleukin-8, and CT images showed a medical "white" lung". According to the experience of SARS treatment in 2003, the use of hormones will indeed help the patients to alleviate their illness, but patients who survived SARS either had too much hormone at that time and took too long. Although the lungs could recover, but the femoral head was necrotic Either the amount of hormones was very conservative at the time, which kept the lungs in the storm of inflammatory factors, leading to the emergence of irreversible pulmonary fibrosis. So is there a medicine that can anti-inflammatory, reduce the load of hormone use, and have the effect of treating and preventing pulmonary fibrosis complicated by severe viral lung? At present, pirfenidone has achieved encouraging results in the treatment of idiopathic Pulmonary Fibrosis (CTD-ILD) diseases. It is particularly encouraging that the values announced at the 2019 ATS Annual Conference suggest that pirfenidone has more anti-inflammatory and anti-oxidant effects than its own outstanding anti-fibrotic ability. The data shows early use, Its strong anti-SOD activity can effectively inhibit IL-1beta and IL-4, and can open the prevention mode of pulmonary interstitial fibrosis. Based on the above, this project intends to make the following scientific assumptions: based on the homology of the pathogens of the new coronavirus-infected pneumonia and the coronavirus infection of pneumonia in 2003, the similarities in the occurrence and development of the disease, that is, the pulmonary inflammatory storm occurs first, and thereafter The progress of fibrosis and the progressive decline of lung function and mortality are higher than those of ordinary pneumonia. We hope that by adding pirfenidone as a treatment program in addition to standard treatment, it will be a new and severe type of coronavirus infection. Patient clinical treatment provides an effective and practical method.

This is a phase I, open-label, dose-ranging clinical trial in males and non-pregnant females, starting at 18 years of age, inclusive, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety, reactogenicity and immunogenicity of mRNA-1273 manufactured by ModernaTX, Inc. mRNA-1273 is a novel lipid nanoparticle (LNP)-encapsulated mRNA-based vaccine that encodes for a full-length, prefusion stabilized spike (S) protein of SARS-CoV-2. Enrollment will occur at up to 3 domestic clinical research sites. Up to one hundred and fifty-five subjects will be enrolled into one of thirteen cohorts (10 micrograms [mcg], 25 mcg, 50 mcg, 100 mcg, and 250 mcg). Subjects will receive an intramuscular (IM) injection (0.5 milliliters [mL]) of mRNA-1273 on Days 1 and 29 in the deltoid muscle and will be followed through 12 months post second vaccination (Day 394). Follow-up visits will occur 1, 2, and 4 weeks post each vaccination (Days 8, 15, 29, 36, 43, and 57), as well as 3, 6, and 12 months post second vaccination (Days 119, 209, and 394). The primary objective is to evaluate the safety and reactogenicity of a 2-dose vaccination schedule of mRNA-1273, given 28 days apart, across 5 dosages in healthy adults. Optional Substudy: This is an optional third mRNA-1273 vaccination substudy, in subjects 18 years of age and older, who received both the first and second mRNA-1273 vaccinations in the main study and meet all other substudy eligibility criteria. This optional third mRNA-1273 vaccination substudy is designed to assess safety, reactogenicity, and immunogenicity through 12 months post third vaccination (Day 731). Subjects who receive the third mRNA-1273 vaccination will exit the Schedule of Activities for the main study and will enter the Schedule of Activities for the optional substudy. Up to one hundred and twenty subject will be enrolled into two cohorts (consisting of participating subjects who received 2 doses of 25 or 50 mcg and participating subjects who received 2 doses of 100 and 250 mcg). Subjects will receive an IM injection (0.5 mL) at a dosage of 100 mcg/0.5 mL. The primary objective is to evaluate the safety and reactogenicity of a third mRNA-1273 vaccination, at a dosage of 100 mcg.

Since Dec 2019, over 70000 novel coronavirus infection pneumonia (NCIP) patients were confirmed. 2019 novel coronavirus (2019 nCoV) is a RNA virus, which spread mainly from person-to-person contact. Most of the symptoms are non-specific, including fever, fatigue, dry cough. Sever NCIP patients may have shortness of breath and dyspnea, and progress to acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS). The mortality is reported to be around 2.3%. Thus, early detection and early treatment is very important to the improvement of NCIP patients' prognosis. At present, NCIP RNA detection of pharyngeal swab specimen by RT-PCR is recommended. However, due to the universal susceptibility to 2019 nCoV in general population and limited number of NCIP RNA detection kits available, to identify an efficient screening strategy is urgently needed. This study aim to develop and validate the diagnostic accuracy and screening efficiency of a new NCIP screening strategy, which can benefit the disease prevention and control.

Outbreak of 2019 Novel Coronavirus infection started in Wuhan and quickly spread to the world. Suspected patients were isolated and treated in our department. Clinical data was recorded to investigate the clinical features of patients confirmed and excluded diagnosed of 2019 Novel Coronavirus infection.

Although immune-inflammatory treatment is not routinely recommended to be used for SARS-CoV-2 pneumonia, according to the pathological findings of pulmonary oedema and hyaline membrane formation, timely and appropriate use of immune modulator together with ventilator support should be considered for the severe patients to prevent ARDS development. The sphingosine-1-phosphate receptor regulators Fingolimod (FTY720) is an effective immunology modulator which has been widely used in multiple sclerosis.The aim of this study was to determine whether the efficacy of fingolimod for a novel coronavirus disease (COVID-19).
