Filter by:This is a multi-center, randomized, double-blind, placebo-controlled clinical trial to evaluate a 21-herb formula named modified Qing Fei Pai Du Tang (mQFPD) to treat COVID-19-positive outpatients with mild-to-moderate symptoms assigned to self-quarantined and home management. This the study aims to establish the safety and feasibility of the use of mQFPD vs placebo in 66 total subjects. Subsequent trials will evaluate other therapeutics as well as the efficacy of mQFPD in a larger study population.
This is a retrospective non-randomized clinical study of 60 patients total to assess the effects of SARS-CoV-2 infection and the SARS-CoV-2 vaccination. This study will have 2 arms evaluating the epigenomes of patients pre and post-exposure to one of the interventions. The first arm of the study will analyze 40 patients' epigenomes whose DNA methylation was examined pre and post SARS-CoV-2 infection. The second arm of this study is analyzing 20 patients' epigenomes whose DNA methylation was examined pre and post-injection of the SARS-CoV-2 vaccine.
Introduction: SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), the new coronavirus, causes a disease called COVID-19 that can trigger aggressive inflammatory responses. In this sense, inhaled corticosteroid therapy (IC) has shown some favorable results in controlling the worsening of the disease, given that it has effects on pulmonary inflammation and can be an intervention to be used in the mild manifestations of COVID-19 in order to prevent disease progression and severity. Regarding the role of bronchodilators, studies have suggested that their combination with IC exerts synergistic therapeutic effects. Objective: To determine the efficacy of inhaled therapy of beclomethasone/formoterol/glycopyrronium (BFG) (100/6/12.5mcg) and/or beclomethasone HFA 250 mcg in preventing the use of healthcare resources in patients ≥ 18 years of age at 28 days compared to usual care. Method: participants will be randomized according to a ratio of 1:1:1 into three groups: (Group 1) Standard of care + BFG two doses 2x/day; (Group 2) standard treatment + beclomethasone HFA two doses 2x/day and (Group 3) standard treatment. After collecting the signed informed consent form, research participants will be treated for 28 days and, after two days, will undergo a spirometry test. Therefore, the total duration of the study for a given participant will be up to 30 days.
The purpose of this study is to evaluate the safety, immunogenicity, and efficacy of Nanocovax vaccine in volunteer subjects 18 years of age and older.
Novel Coronavirus Pneumonia (COVID-19) is the pneumonia caused by the 2019 novel coronavirus infection. Critically ill patients with this disease develop dyspnea and hypoxemia, and even further aggravate acute respiratory distress syndrome, septic shock, coagulation dysfunction, and multiple organ failure. Since February 15, 2020, the 171-member medical team of the Second Affiliated Hospital of Zhejiang University School of Medicine has taken over the Intensive Care Unit of the Cancer Center of the Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology and the Intensive Care Unit of the West Hospital of Union Hospital to carry out severe and critical care. Treatment of patients with new coronary pneumonia. In clinical practice, combined with the changes in chest CT imaging of severe COVID-19 patients, it has been found that some laboratory indicators of severe patients can effectively judge the clinical prognosis and outcome of patients, but there is no relevant retrospective study with large sample size so far.
This observational cohort study will enroll patients in LMICs with suspected or confirmed COVID-19 on oxygen or deemed to require oxygen therapy based on objective criteria. Demographics and risk factor information will be collected from participants. Participants will be followed for 7 days or until outcome (hospital discharge or death). Facility level metrics on oxygen availability will also be collected at the beginning of site enrolment.
Prospective study in a group of patients with COVID-19 pneumonia.
This study is a prospective, observational multicentric study. The study population entails adult patients hospitalized with a high clinical suspicion of COVID-19 and consists of two study arms (SARS-CoV2- vs. SARS-CoV2+).This combined fundamental research project has a dual goal: on the one hand assessing immunological predisposing factors for severe infection and investigating the immunological impact of SARS-CoV2 infection, on the other hand studying viral characteristics. Furthermore, a substudy will examine the pharmacokinetics and pharmacodynamics of hydroxychloroquine in patients receiving this antiviral treatment (REVIVE susbstudy). To answer these research questions, samples will be collected from patients with a high clinical suspicion of COVID-19, hospitalized at UZ Gent and 2 participating hospitals in Ghent (AZ Maria Middelares en AZ Jan Palfijn).
The purpose of this Phase III study is to assess the efficacy, safety, and immunogenicity of two CoV2 preS dTM-AS03 vaccines (monovalent and bivalent) as part of primary series vaccinations in a multi-stage approach, as well as a booster injection of a CoV2 preS dTM-AS03 vaccine, in adults 18 years of age and older. A total of approximately 21 046 participants are planned to be enrolled (5080 per study intervention group in Stage 1 and 5443 per study intervention group in Stage 2). Initial, double-blind, primary series study design is planned for 365 days post-last Initial injection (ie, approximately 386 days total) for each participant. Based on decisions of the Study Oversight Group, Stage 1 and Stage 2 participants will be invited to participate in an unblinded Crossover / Booster study design with duration as follows: - For participants who initially received vaccine: 12 months post-booster (ie, approximately 18 to 24 months) - For participants who initially received placebo: ≥ 4 months post-last dose of the primary series + 12 months post-booster (ie, approximately 28 to 34 months) - For participants who do not consent to continue in the unblinded Crossover / Booster part of the study, all study procedures will be stopped and participants will be discontinued from the study.
This Phase III study is a global multicenter, randomized, double-blind,placebo controlled clinical trial to evaluate the efficacy, safety, and immunogenicity of therecombinant COVID-19 vaccine (Sf9 cells) in 40,000 participants aged 18 years and older who do not have a known history of SARS-CoV-2 infection but whose locations or circumstances put them at appreciable risk of acquiring COVID-19 or SARS-CoV-2 infection.
