Study Description

Brief Summary:

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

Condition or disease	Intervention/treatment	Phase
COVID-19 Disease	Drug: LAU-7b; Drug: Placebo oral capsule	Phase 2

Detailed Description:

RESOLUTION is a multicenter, randomized, double-blind, placebo-controlled Phase 2 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.

Outcome Measures

Primary Outcome Measures :

1. Proportion of patients alive and free of respiratory failure (Ordinal Scale scores 1-4) [ Time Frame: On Day 29 ]

   This will be assessed through health status scoring using the World Health Organization 7-point Ordinal Scale, a higher score is worse than a low score.

   1. Not hospitalized, no limitations on activities;
   2. Not hospitalized, limitation on activities;
   3. Hospitalized, not requiring supplemental oxygen;
   4. Hospitalized, requiring supplemental oxygen;
   5. Hospitalized, on non-invasive ventilation or high flow oxygen devices;
   6. Hospitalized, on invasive mechanical ventilation or extra-corporeal membrane oxygenation;
   7. Death.

Secondary Outcome Measures :

1. The safety of LAU-7b therapy will be assessed through the monitoring of treatment emergent adverse events, compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through monitoring and probing

   This will be assessed through Day 60 health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
4. Rate of COVID-19 disease-related aggravation, depicted by a change from baseline in the ordinal scale score of at least one category, compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through daily health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
5. Rate of COVID-19 disease-related transfer to intensive care unit, depicted by a change from baseline in the ordinal scale score to categories 5 or 6, compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through daily health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
6. Rate of COVID-19 disease-related transfer to mechanical ventilation, depicted by a change from baseline in the ordinal scale score to category 6, compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through daily health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
7. Mean change from baseline of the ordinal scale patient health status as a function of assessment time, compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through daily health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
8. Time to an improvement of one category on the ordinal scale patient health status, compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through daily health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
9. Time to recovery, defined here as the time to reach categories 2 or 1 on the ordinal scale patient health status (first occurrence if more than once), compared to placebo [ Time Frame: From baseline to Day 60 ]
   This will be assessed through daily health status scoring using the World Health Organization 7-point Ordinal Scale (shown with the primary outcome measure), a higher score is worse than a low score.
