Background COVID-19 is a novel and highly virulent virus, which caused a rapid and massive onset of clinical trials in a short period of time.With the aim to obtain suggestions in the guidance on performing public health emergency clinical trials, and control this virus in China and other countries and for the prevention of the onset of other infectious viruses in the future. Methods COVID-19, SARS, MERS and Ebola clinical trials registered in the Chinese clinical trial registry and clinical trials.gov were collected and analyzed and intervention protocols were descriptively analyzed, focusing on the analysis and comparison of the drug used. The search period ended on February 24, 2020. Results The number of the registered COVID-19 clinical trials was 295. Among 203 intervention trials, 78.3% (159) were drug clinical trials. The 159 COVID-19 trials were designed and analyzed with the highest proportion of random, open control study [66.0% (105)], and blind randomized trials [13.8% (22)]. The drug mostly used was Lopinavir/Ritonavir (15.1%). The sample size median 100,IQR(interquartile range) 140. The number of the registered SARS was 6, MERS 15, and Ebola 97. Among 3 MERS and 19 Ebola drug intervention clinical trials, MERS and Ebola were randomized, blind, and placebo-controlled drug clinical trials accounting for 100% (3) and 31.6% (6), respectively, while SARS were vaccine trials, without drug intervention clinical trials registered. Conclusions Some of the COVID-19 clinical trials and drug selection performed are somewhat disordered, requiring greater attention to the needs, science assumptions, ethics and quality management of the clinical research. Thus, during the epidemic period, the country should deliver guidance on how to perform appropriate emergency clinical trials, design a scientifically based clinical trial program and focus on researching drugs or vaccines that have great potential.
In March 2003, a novel coronavirus (SARS-CoV) was discovered in association with cases of severe acute respiratorysyndrome (SARS). The sequence of the complete genome of SARS-CoV was determined, and the initial characterization of the viral genome is presented in this report. The genome of SARS-CoV is 29,727 nucleotides in length and has 11 open reading frames, and its genome organization is similar to that of other coronaviruses. Phylogenetic analyses and sequence comparisons showed that SARS-CoV is not closelyrelated to anyof the previouslycharacterized coronaviruses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
