Overview

Brief Summary

The purpose of this study is to evaluate the safety and tolerability of single ascending IV dose administrations of GIGA-2050 in patients hospitalized with COVID-19.

Detailed Description

This is a Phase 1, first in human (FIH) study utilizing a 3+3 design to assess the safety and pharmacology of single ascending doses (SAD) of GIGA-2050 in patients hospitalized with confirmed COVID-19. Participants will receive a single intravenous (IV) infusion dose of GIGA-2050 and followed for safety, pharmacology and efficacy assessments during hospitalization, after discharge (if applicable), and through study discontinuation or end of study visit (Day 56).

•Requires oxygen supplementation with FIO2 approximately 30% or greater administered by nasal cannula, mask, or NIV.
•Participants can be on other medication on-label to treat COVID-19 respiratory disease that the Investigator deems clinically relevant in combination with the study drug, including corticosteroids. Passage of 24 hours after administration of the EUA drug will be required prior to dosing GIGA-
