Clinical Trial Summary

This is the first-in-human phase 1/2a trial of the inhaled 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.

Description:

The phase 1 component of this trial consists of a single-inhalation open-label dose-escalation phase (Groups 1A-1C and Groups 2A-2C). Subsequently, the highest tolerated dose tested will be administered to an expansion cohort of SARS-CoV-2-infected individuals (Group 2D). In this randomized and blinded group, participants will receive DZIF-10c or placebo both by inhalation and intravenous infusion.
