Brief summary

This is an early-stage clinical trial to determine a safe and effective dose for Tivoxavir Marboxil (TRX-100) in patients with mild to moderate Influenza. Participants will take a study drug as well as a standard therapy. A descriptive statistics will be used to present the study results.

Detailed description

This is a multicenter, open-label, randomized, Phase 2a study to evaluate the safety, tolerability, and pilot efficacy of different oral doses of TRX-100 in otherwise healthy participants with mild to moderate influenza. The study will also evaluate PK of TRX-100 and its major active metabolite, TRX-101, following single oral doses of TRX-100.
