End point description

Participants were considered alive and free of respiratory failure if they were in category 1,2,3 or 4 from the GSK modified version ordinal scale adapted from World Health Organization (WHO) scale 2020.The 8-point scale was as follows:1)Non-hospitalized,no limitation of activity;2) Non-hospitalized,limitation of activity;3) Hospitalized,no oxygen therapy;4)Hospitalized,low-flow oxygen by mask/nasal prongs;5) Hospitalized,highflow oxygen (>=15 liters per minute),continuous positive airway pressure(CPAP),bilevel positive airway pressure(BIPAP),non-invasive ventilation;6) Hospitalized,intubation and mechanical ventilation;7) Hospitalized,mechanical ventilation plus additional organ support;8)Death.Higher scale indicate higher intensity of respiratory failure. Percentage values are rounded off.Modified intent to treat(mITT) population consisted of all randomized participants who received study intervention.Only those participants with data available at specified timepoints were analyzed

End point description

Participants were independent of supplementary oxygen if they were in category 1, 2 or 3 from the GlaxoSmithKline (GSK) modified ordinal scale adapted from World Health Organization (WHO) scale 2020. The 8-point scale was as follows: 1) Non-hospitalized, no limitation of activity; 2) Non-hospitalized,limitation of activity; 3) Hospitalized, no oxygen therapy; 4) Hospitalized, low-flow oxygen by mask or nasal prongs; 5) Hospitalized, highflow oxygen (>=15L/min), continuous positive airway pressure (CPAP), bilevel positive airway pressure (BIPAP), non-invasive ventilation; 6) Hospitalized, intubation and mechanical ventilation; 7) Hospitalized, mechanical ventilation plus additional organ support; 8) Death. Percentage values are rounded off. Only those participants with data available at the specified time points were analyzed.

Were there any global substantial amendments to the protocol? Yes

18 May 2020

Amendment 1: Modifications to the protocol in response to regulatory feedback, and clarifications based on investigator feedback. The key change is revision of the primary endpoint (where definition of “free of respiratory failure” is participants in categories 1-4 on GlaxoSmithKline [GSK] Ordinal Scale). Other changes are (1) to revise recording of blood pressure and pulse rate; (2) to add details of randomization caps; (3) to simplify/clarify some Inclusion and Exclusion Criteria; (4) to clarify medications permitted during the study.

Amendment 2: Modifications to the protocol in response to regulatory and ethics committee feedback, and clarifications based on investigator feedback. The main changes are (1) clarification that Day 1 pre-dose assessments do not need to be repeated if Screening and Randomization are within 24 hours; (2) expedited reporting of cytokine release syndrome (CRS) as an adverse event of special interest (AESI); (3) clarification that organ transplant participants are excluded per Exclusion Criteria #11; (4) clarification of conditions by which convalescent plasma is permitted or not during the study; (5) removed specific mention of chloroquine and hydroxychloroquine; (6) expanded the null hypothesis; (7) consent may be collected before the 48hour screening window.

Amendment 3: Before the last of 806 participants completed the study (Last Subject Last Visit, Day 60), an interim analysis of the primary endpoint and all-cause mortality data at Day 28 showed that substantial clinical benefit was evident in one of the pre-defined stratification subgroups “Age 70 to less than (<)80 years”, with no safety concerns in any subgroup. Given the ongoing pandemic and particularly high mortality of Coronavirus Disease-2019 (COVID-19) disease in participants over 70 years old, together with recent publications that support the hypothesis that the severity of the disease is driven by a maladaptive innate immune response in which Granulocyte-macrophage colony stimulating factor (GM-CSF) plays a key role and which is more commonly elevated in older participants. GSK has therefore determined to urgently confirm these subgroup findings by amending the protocol to allow the enrolment of an additional cohort of participants aged 70 years and above with no upper age limit. GSK has reviewed the results from what is now considered as the first part of the study (Part 1) and decided that a second part will be added to the study (Part 2) which has less frequent assessments to decrease the burden on sites
