The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT04275245
Recruitment Status : Completed
First Posted : February 19, 2020
Last Update Posted : April 9, 2021

Tang-Du Hospital

Brief Summary:
To evaluate the safety and efficacy of humanized Meplazumab for Injection in patients infected by 2019-nCoA.

Condition or disease Intervention/treatment Phase
Coronavirus Disease 2019 (COVID-19) Drug: Meplazumab for Injection Phase 1 Phase 2

Detailed Description:
According to the results of nonclinical study of humanized Meplazumab for Injection, a single dose will be used for the treatment. The treatment plan is first dose on the first day (0d) and second dose on the second day (1D) of the treatment period by intravenous(IV) infusion, each dose 10mg; The third dose will be given within 3-5 days after the second dose according to the patient's 2019-nCoV nucleic acid load, clinical manifestations and the overall evaluation of doctors, dose is 10mg. 30 mg of methylprednisolone will be given intravenously 30 minutes before each administration. Each subject will be evaluated the therapeutic effect within 28 days after the first administration, and to determine the preliminary therapeutic effect, safety and tolerability of humanized Meplazumab for Injection.
