Study of LAU-7b for the Treatment of COVID-19 Disease in Adults (RESOLUTION)

RESOLUTION: A Double-blind, Randomized, Placebo-controlled, Phase II/III Study of the Efficacy and Safety of LAU-7b in the Treatment of Adult Hospitalized Patients With COVID-19 Disease

A randomized, double-blind, placebo-controlled Phase 2/3 Study of LAU-7b against confirmed COVID-19 Disease in hospitalized patients at a higher risk of complications.

Study Overview

• Status: Active, not recruiting
• Conditions: COVID-19 Disease
• Intervention / Treatment: Drug: LAU-7b; Drug: Placebo oral capsule

Detailed Description

RESOLUTION is a multicenter, randomized, double-blind, placebo-controlled Phase 2/3 study of LAU-7b for the treatment of COVID-19 Disease in patients at a higher risk than the general COVID-19 Disease population to develop complications while hospitalized.

The goal of the study is to evaluate the efficacy of LAU-7b therapy + standard-of-care relative to placebo + standard-of-care in patients with COVID-19 Disease with confirmed SARS-CoV-2 infection.

The purpose of the treatment with LAU-7b is to prevent the worsening of the health of hospitalized patients including aggravation such as recourse to mechanical ventilation and death.

The means are the direct effects of LAU-7b on the resolution of inflammation, interference with viral proliferation and protection from excessive pro-inflammatory response.
