The subjects are able to understand the content of the study and voluntary to sign the informed consent form; meanwhile, being able to complete the study as required in the protocol

Exclusion Criteria

Excluded for novel coronavirus (SARS-CoV-2) infection
Having one of the following evidence on SARS-CoV-2 infection
SARS-CoV-2 determined by reverse transcription-polymerase chain reaction (RT-PCR) and/or next generation sequencing (NGS) in diagnostic specimens (nasopharyngeal swabs) during screening and pre-randomization (results within 3 days before randomization are accepted)
Previous viral gene sequencing showed high homology with the known SARS-CoV-2
Positive specific antibody IgM or IgG against serum SARS-CoV-2; Excluded for previous and concomitant medications
Previous vaccination of SARS-CoV-2 vaccine or having participated in the clinical trial on SARS-CoV-2 neutralizing antibody
Use of therapeutic biologics within 12 weeks prior to screening, or remaining in the elimination period of the drug (within 5 half-lives) at random administration, whichever is longer
Participation in any other clinical study with intervention of investigational product within 4 weeks prior to screening, or remaining in the elimination period of the drug (within 5 half-lives) prior to screening, whichever is longer
Vaccination of vaccine within 12 weeks prior to screening, or plan to use Bacille Calmette-Gurin vaccine or other vaccine during the study and within 12 weeks after the study

Any major surgery within 8 weeks (inclusive) prior to screening, or requiring such surgery during the study, and such surgery is considered by the investigator to possibly bring unacceptable risk for subjects upon confirmation with the sponsor; Abnormal physical examination, laboratory examination and history
Lying systolic blood pressure (SBP) > 140 mmHg or < 90 mmHg, and/or diastolic blood pressure (DBP) > 90 mmHg or < 50 mmHg at screening and randomization
Total white blood cell (WBC) count < 3.5 x 109/L, platelet < 140 x 109/L, neutrophil < 2.0 x 109/L, or hemoglobin decreased (male < 135 g/L, female < 120 g/L), lymphocytes < 1.0 x 109/L at screening
ALT or AST > 2 upper limit of normal, or eGFR 90 mL/min/1.73m2 at screening
Abnormal ECG at screening, single QTcF > 450 msec, and/or other abnormalities of clinical significance, unacceptable risk that may be brought by participation in the study
History of HIV infection, and/or positive aiti-HIV antibody, positive hepatitis B surface antigen (HBsAg), positive hepatitis C antibody (anti-HCV), or positivetreponema pallidum particle agglutination test (TPPA) at screening
History of transplantation of vital organs (e.g., heart, lung, liver, kidney, etc.)
Having malignant tumor (excluding the malignant tumor cured with no recurrence in the past 5 years, completely resected basal cell and squamous cell carcinoma of skin, completely resected carcinoma in situ of any type)
Other major diseases within one year
Medical history and previous history suggest the following diseases: including but not limited to gastrointestinal, renal, hepatic, neurological, hematological, endocrine, oncological, pulmonary, immune, mental or cerebro- and cardiovascular diseases; Substance abuse, alcohol abuse
History of drug abuse or use of narcotics in the past 5 years, or positive urine drug screening
History of alcohol abuse or intake of excessive alcohol in the past 6 months (14 units of alcohol per week: 1 unit = 285 mL beer, or 25 mL liquor, or 100 mL wine), or alcohol test positive; History of allergies
Known serious allergic reaction or hypersensitive to food, inhaled and contact material as well as drugs, or allergic constitution (allergy to various drugs and food)
Known history of allergy or hypersensitivity to the investigational drug, other monoclonal antibody drugs and therapeutic protein preparations (fresh or frozen plasma, human serum albumin, cytokine, interleukin etc.); Pregnancy, lactation
Positive -Human Chorionic Gonadotropin (-HCG) or breastfeeding female subjects; Blood loss and others
Subjects who lost blood or donated more than 400 mL, or received blood transfusion in the past 3 months; or plan to donate blood during the study
Any other condition that the subject is considered by the investigator as inappropriate to participate in the study, for example, potential compliance issue, inability to complete all the tests and evaluations according to the requirements in the protocol, or uncontrolled mental, neurological or psychological disorders, participation in the study is judged by the investigator to be associated with uncontrollable risk
