Filter by:This study is a research project to evaluate the efficacy of hydroxychloroquine for post-exposure prophylaxis and early treatment of Covid-19. The intervention entails administering prophylactic hydroxychloroquine to all contacts (Study 1) and treating non severe confirmed cases with hydroxychloroquine (Study 2).
The study is a double-blind, randomised, placebo-controlled trial that will be conducted primarily in healthcare settings and other facilities directly involved in COVID-19 case management. We will recruit healthcare workers and other persons at risk of contracting COVID-19, who can be followed reliably for 5 months. The initial aim was to recruit 40,000 participants and we predict an average of 400-800 participants per site in 50-100 sites. The participant will be randomised to receive either chloroquine or placebo (1:1 randomisation), or to hydroxychloroquine or placebo (1:1 randomisation). A loading dose of 10mg base/kg (four 155mg tablets for a 60kg subject), followed by 155 mg daily (250mg chloroquine phosphate salt/ 200mg hydroxychloroquine sulphate) will be taken for 3 months. If the participant is diagnosed with COVID-19, they will take continue to take the study medication until: - 90 days after enrolment (i.e., completion of kit) - hospitalised due to COVID-19 disease (i.e., not for quarantine purposes) in which case they will stop, or - advised to stop by their healthcare professional for other reasons Episodes of symptomatic respiratory illness, including symptomatic COVID-19, and clinical outcomes will be recorded in the Case Record Form during the follow-up period. This study is funded by Wellcome Trust Grant reference 221307/Z/20/Z.
A 6-Week Prospective, Open label, Randomized, in Multicenter Study of, Oseltamivir 300mg per day plus Hydroxychloroquine 800 mg per day versus Combination of Lopipinavir 800mg (or 10 mg/kg ) per day and Ritonavir 200 mg ( or 2.5 mg/kg ) per day plus Oseltamivir 300 mg ( or 4-6 mg /kg ) per day versus Combination of Darunavir 400 mg every 8 hours plus ritonavir 200 mg (or 2.5 mg/kg ) per day plus Oseltamivir 300mg ( or 4-6 mg /kg ) per day plus Hydroxychloroquine 400 mg per day in mild COVID-19 and Combination of Lopipinavir 800 mg (or 10 mg/kg ) per day and Ritonavir 200 mg ( or 2.5 mg/kg ) per day plus Oseltamivir 300 mg ( or 4-6 mg /kg ) per day versus Favipiravir 2400 mg, 2400 mg, and 1200 mg every 8 h on day 1, and a maintenance dose of 1200 mg twice a day plus Lopipinavir 800 mg ( or 10 mg/kg ) per day and Ritonavir 200 mg ( or 2.5 mg/kg ) per day versus Combination of Darunavir 400 mg every 8 hours plus ritonavir 200 mg (or 2.5 mg/kg ) plus Oseltamivir 300 mg (or 4-6 mg /kg ) per day plus Hydroxychloroquine 400 mg per day versus Favipiravir 2400 mg, 2400 mg, and 1200 mg every 8 h on day 1, and a maintenance dose of 1200 mg twice a day plus Darunavir 400 mg every 8 hours Ritonavir 200 mg ( or 2.5 mg/kg ) per day plus Hydroxychloroquine 400 mg per day in moderate to critically illness in COVID-19
Disease caused by 2019 Novel Coronavirus also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
Evaluation of novel coronavirus induced severe pneumonia by dental pulp mesenchymal stem cells
In December 2019, viral pneumonia (Covid-19) caused by a novel beta-coronavirus (SARS-CoV-2) broke out in Wuhan, China. Some patients rapidly progressed and suffered severe acute respiratory failure and died, making it imperative to develop a safe and effective vaccine to treat and prevent severe Covid-19 pneumonia. Based on detailed analysis of the viral genome and search for potential immunogenic targets, a synthetic minigene has been engineered based on conserved domains of the viral structural proteins and a polyprotein protease. The infection of Covid-19 is mediated through binding of the Spike protein to the ACEII receptor, and the viral replication depends on molecular mechanisms of all of these viral proteins. This trial proposes to develop universal vaccine and test innovative Covid-19 minigenes engineered based on multiple viral genes, using an efficient lentiviral vector system (NHP/TYF) to express viral proteins and immune modulatory genes to modify artificial antigen presenting cells (aAPC) and to activate T cells. In this study, the safety and immune reactivity of this aAPC vaccine will be investigated.
To analyze the intubation with severe covid-19 pneumonia, the infection rate of anesthesiologist after intubation, and summarizes the experience of how to avoid the infection of anesthesiologist and ensure the safety of patients with severe covid-19 pneumonia.
This is a Phase IIb study consisting of two cohorts to evaluate efficacy, safety and pharmacokinetics of DAS181 in IFV infection. An approximate total of 280 subjects will be enrolled into this study.
In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia of unknown cause. In a short time, Chinese scientists had shared the genome information of a novel coronavirus (2019-nCoV) from these pneumonia patients and developed a real-time reverse transcription PCR (real time RT-PCR) diagnostic assay. In view of the fact that there is currently no effective antiviral therapy, the prevention or treatment of lung injury caused by COVID-19 can be an alternative target for current treatment. Xiyanping injection has anti-inflammatory and immune regulation effects. This study is a Randomized, Parallel Controlled Clinical Study to treat patients with COVID-19 infection.
New coronavirus infection is an important cause of public health emergencies at home and abroad, which seriously affects people's health and social stability. The outbreak of SRAR-COV in China in 2003 caused serious social impact. From January 2002 to August 7, 2003, there were a total of 8,422 cases worldwide, involving 32 countries and regions, of which 919 cases were fatal, with a fatality rate of nearly 11%. The fatality rate of elderly patients and patients with underlying diseases was even more high.There is no precise and effective treatment for coronavirus infection. In vitro, IFN-α2β has inhibitory effects on MERS-CoV and closely related coronavirus severe acute respiratory syndrome (SARS) -CoV. A study showed the effects of interferon-α2β and ribavirin on the replication of nCoV isolates hCoV-EMC / 2012 in Vero and LLC-MK2 cells. The combined application may be useful for the management of patients with nCoV infection in the future. At present, the combination therapy of interferon α2β and ribavirin has been successfully applied in the initial treatment and prevention of SARS and MERS.The purpose of this study was to evaluate the efficacy and safety of recombinant human interferon α1β in treating patients with new coronavirus infection in Wuhan.
