9.2-Clinical trial information points

• According to the clinical trial registration information, the trial group will be administered lopinavir/ritonavir tablets (each containing 200mg lopinavir and 50mg ritonavir), twice daily, and 2 tablets per time, and also interferon α2b, while the control group will receive the conventional treatment.

Part X: Remdesivir

According to the news of the China-Japan Friendship Hospital on the noon of Feb. 2, 2020, the China-Japan Friendship Hospital will lead the clinical study of treating 2019-nCoV with remdesivir in 2019-nCoV-affected Wuhan.

• The subjects of the clinical trial are divided into 2 groups, with one receiving remdesivir treatment and the other one receiving placebo treatment.

Additional remarks: 17 pieces of related information can be searched on the website of the Chinese Clinical Trial Registry (CHICTR) by searching keywords such as coronavirus. In addition to the above information relating to the specific drugs, there is much more information on clinical therapeutic regimens. Interested readers can search for and read such information themselves.

P.S.

According to the announcement of Staidson (300204) on the evening of Feb. 2, 2020, the company and its wholly-owned subsidiary Beijing Defengrui Biological Technology Co., Ltd. (hereinafter referred to as "Defengrui") have applied to the NMPA for the clinical trial of treating the related diseases caused by coronavirus with BDB-001 Injection.

Specifically, the name of the pharmaceutical product in this application is BDB-001 Injection, and the proposed indication is the complement system that can be specifically overactivated by the coronavirus. The product can inhibit the inflammatory responses caused by complement system activation as a result of factors such as viruses, treat persons infected by the coronavirus, etc., prevent pneumonia, prevent pneumonia from worsening and reduce the incidence of acute respiratory distress syndrome.

Conclusion

The collection time of the information summarized above is Feb. 2, 2020, which will change with the progress of scientific research. Interested readers can search for the latest information themselves. Moreover, there is currently no drug proven to be effective against the novel coronavirus pneumonia. Before the above clinical trials end and come to definite conclusions, isolation and infection prevention are still necessary means.
