Brief summary: The purpose of this study is to evaluate the tolerability, safety, pharmacokinetics of SCTA01(anti-SARS-CoV-2 monoclonal antibody) in Healthy Chinese Subjects.

Detailed description: This is a Phase 1, First-in-Human, Randomized, Double-blinded, Placebo-Controlled, Single Ascending Dose Study of SCTA01(Anti-SARS-CoV-2 monoclonal antibody) in Healthy Chinese Subjects.

Dose escalation will be guided by a safety review of clinical signs and symptoms, adverse events (AEs), and laboratory results of the prior dose cohort.

An Interim analysis will be performed after Day 28 post-dose for the last dose cohort for review.
