E.2.1 | Main objective of the trial |
Part 1 The objectives are: • Evaluate the safety and tolerability of inhaled TD-0903 in subjects with COVID-19 • Assess the plasma pharmacokinetics (PK) of TD-0903 in subjects with COVID-19 • Characterize the effect of TD-0903 on reducing the acute lung injury as measured by SaO2/FiO2 ratio associated with COVID-19 • Explore the effect of TD-0903 on nasal swab viral load, and blood biomarkers
Part 2 The primary objectives are: • To characterize the efficacy of TD-0903 in reducing the acute lung injury as measured by SaO2/FiO2 ratio associated with COVID-19 • To characterize the efficacy of TD-0903 as measured by ventilator-free days (VFDs) |

Hospitalized (or documentation of a plan to admit to the hospital if the subject is in an emergency department) and requiring supplemental oxygen to maintain saturation > 90% 5. Confirmed symptomatic COVID-19. If testing results are not immediately available, strong clinical suspicion of COVID-19 can be used for inclusion. Testing should still be done in these subjects. Strong clinical suspicion includes: At least 2 of the following: • Fever • Cough • Fatigue • Dyspnea; and At least 1 of the following • Radiographic evidence of viral pneumonia • Close contact with a patient who has previously tested positive for COVID-19 6.
