Description of intervention(s) / exposure

Intervention code [1] 317594 0
Treatment: Drugs
Comparator / control treatment
Standard of care:

There is no specific antiviral treatment recommended for COVID-19. Standard treatment is symptomatic, and may include oxygen therapy and intubation and protective mechanical ventilation, as well as pharmacologic therapies such as corticosteroids, antiviral agents (e.g. remdesivir), immunomodulators (e.g. chloroquine), serotherapy, anticoagulant therapy and inflammatory inhibitors (e.g. tocilizumab).
Treatment will be directed at the underlying cause of ARDS, as well as supportive measures to ensure adequate tissue oxygenation. Such supportive measures would include supplemental oxygen therapy and/or mechanical ventilation (either non-invasive or invasive via endotracheal tube). There is currently no specific pharmacotherapy proven to be effective in ARDS.
Treatment of both conditions will vary based on hospital processes and the specific condition of the participant.

Outcomes
Primary outcome [1] 323807 0
To compare COVID-19 WHO score greater than or equal to 2 (for participants with COVID-19) or Dyspnoea Management Questionnaire-30 (for participants with ARDS) breathlessness scores at 6 months. This is composite primary outcome.
Timepoint [1] 323807 0
6 months post randomisation
Primary outcome [2] 323808 0
Maximum oxygen requirement (increase or decrease) over 6 months defined as follows:
- An increase in oxygen requirement will be defined by 1. Increasing oxygen flow rate or FiO2 using the same oxygen delivery device, or 2. Escalation to invasive and non-invasive mechanical ventilation/ECMO or vasopressor/ionotropic support.
- A decrease in oxygen requirement will be defined as a decrease in oxygen flow rate or FiO2 using the same oxygen delivery device, or cessation of oxygen support requirement.

The peak oxygen requirement (i.e. increase from that at baseline) will be recorded, irrespective of the time of occurrence up until discharge and 6 months. Likewise, the greatest decrease will also be recorded, irrespective of the time of occurrence up until discharge and 6 months.

Statistical methods / analysis
COVID-19:
With 300 participants (Australian cohort), the study will offer over 80% power at 2P=0.05, to identify as statistically significant a reduction in mean WHO COVID-19 score at 6 months from 2 (SD 1.5) to 1.5 (SD 1.5). With 50 participants in the monocyte sub-study, differences in monocyte characteristics of less than 25% (SD 10) between groups will be significant at 2P=0.05.
With up to 1,000 participants recruited in total (including international participants), the study would offer >80% power to identify as significant (at 2P=0.05) a reduction of 2 points in WHO COVID-Ordinal Score, 2 days (SD 2) less time in ICU, or death of 20%.

Non-COVID-19 ARDS
With 300 participants, we will have 90% power at 2P=0.05 to identify as statistically significant a reduction from a mean DMQ-30 composite score of 11±4 to 9.5±4 (i.e. <14% improvement).
Similarly, with 1000 participants, the study would offer 90% power at 2P=0.01, to identify as statistically significant, an improvement from 11±4 to 10±4 (i.e an improvement of 9%).

Summary
Brief summary
SARS CoV-2 (COVID-19) is highly infectious, with each case transmitting infection to between 2 to 3 other people. Approximately 15% of COVID-19 infected individuals are hospitalised and 1 in 3 require artificial ventilatory support. Up to a third have a poor prognosis with the main cause of death being overwhelming respiratory failure and/or cardiac failure and cardiac arrest associated with a cytokine storm. Approximately 30% of hospitalised individuals will ultimately require artificial ventilatory support for deteriorating respiratory status while under clinical observation. Conservatively, at least one third of intubated people will succumb to the infection with the most common causes of death being overwhelming respiratory failure associated with acute respiratory distress syndrome (ARDS) and/or cardiac failure and cardiac arrest, both associated with cytokine storm. Over 1.9 million individuals of the 46 million infected individuals globally have died from COVID-19 infection (as of January 2021), with many more deaths projected over the next 6-12 months. Fatal outcomes are thought to be driven by inflammatory responses to the virus resulting in host-mediated tissue damage to the lung, heart, and kidney and a prothrombotic milieu. Approximately 10% of patients with COVID-19 suffer from symptoms beyond 3-4 weeks, labelled as ‘long COVID-19.’ A variety of symptoms are experienced including cough, breathlessness, fever, sore throat, chest pain and cognitive deficits. Oral colchicine has demonstrated striking anti-inflammatory properties in patients with vascular disease and a “single shot” of colchicine markedly suppresses monocyte inflammasome activation, which is pivotal in the cascade leading to the cytokine storm. Troublesome side effects with colchicine appears to be rare. Thus, this treatment may reduce the serious complications associated with COVID-19 and non-COVID-19 ARDS.
