E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of tozorakimab versus placebo as add on to SoC in participants with viral lung infection requiring supplemental oxygen on the prevention of death or progression to IMV/ECMO by Day 60 |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate the effect of tozorakimab versus placebo as add-on to standard of care on:
a) all-cause mortality by Day 60
b) ICU stay
c) duration of oxygen supplementation
d) prolonging time to death or IMV/ECMO
e) prolonging time to death
f) ventilator use
g) ICU admissions
h) duration of hospitalisation
i) clinical status as assessed by the Investigator using WHO 10-category ordinal Clinical Progression Scale by Day 60.
2. To evaluate the pharmacokinetics and immunogenicity of tozorakimab.
3. To evaluate the use of baseline serum biomarker levels to predict treatment response with tozorakimab versus placebo as add on to standard of care.
4. To assess the safety and tolerability of tozorakimab versus placebo as add-on to standard of care. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Adult participants ≥ 18 years old at the time of signing the informed consent form.
2. Patients hospitalised with viral lung infection.
3. Hypoxaemia requiring treatment with supplemental O2 |

E.4 | Principal exclusion criteria |

3. Ongoing or impending IMV/ECMO at randomisation. |
