Inclusion Criteria

  • 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.

Exclusion Criteria

  • 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.
