- Adults, Older adults
- Minimum age
- 18 Years
- Healthy volunteers
- No
- Adult participants ≥ 18 years old at the time of signing the informed consent form.
- Patients hospitalised with viral lung infection.
- Hypoxaemia requiring treatment with supplemental O2.
Hypoxaemia is defined as:
SpO2 ≤ 90% OR
SpO2 ≤ 92% AND one or both of the following:
Radiographic infiltrates by CXR/CT compatible with viral lung infection per investigator judgement.
Use of accessory muscles of respiration or RR (respiratory rate) > 22.
- Patient remains hypoxaemic at randomisation requiring treatment with supplemental oxygen.
- Known fungal or parasitic lung infection, aspiration lung infection, lung abscess, or evidence of septic shock. Bacterial co-infection is allowed, unless, in the opinion of the investigator, bacterial infection defines the severity of the participant's condition.
- Hypoxaemia caused primarily by extrapulmonary insult or by lung injury of non-infective aetiology.
- Ongoing IMV/ECMO at randomisation.
