Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to characterize the impact of inhaled remdesivir (RDV) on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load in participants with early stage coronavirus disease 2019 (COVID-19).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will have multiple parts: Part A, Part B, and Part C. Part B will be conducted if supported by evaluation in healthy volunteers in another Phase 1a Gilead study (GS-US-553-9018). Participants in Part C will be enrolled after review of preliminary safety and available efficacy data from Parts A and B through at least Day 7.

GS-US-553-9018 is a Phase 1a randomized, blinded, placebo-controlled, single- and multiple-dose study in healthy volunteers to evaluate the safety, tolerability, and pharmacokinetics of remdesivir administered by inhalation.
