Primary outcomePrimary: Proportion of Patients With Any AE Within 7 d of Study Drug Infusion — 2; 1; 0; 0 Participants
Summary
This is the first-in-human phase 1/2a trial of the intravenous administration of the SARS-CoV-2-neutralizing monoclonal antibody DZIF-10c in healthy volunteers and SARS-CoV-2-infected individuals. It will evaluate the safety, pharmacokinetic profile, immunogenicity, and antiviral activity of DZIF-10c.
