Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ARM 1 - Prophylaxis
Drug: IFN-a
Dose: 40,000 IU/Daily
Duration: 3 months
Mode: Intranasal spray (self administered)
Adherence: drug return logs, patient reported.

Description of study design:
This SMART design specifies that participants entering the trial who have had no known COVID-19 exposure are initially randomised to either low-dose intranasal IFN-a or placebo as pre-exposure prophylaxis against developing COVID-19. Any participants who have a known COVID-19 exposure are randomised to high-dose IFN-a or placebo as a post-exposure prophylaxis against developing COVID-19. If, at any stage after enrolling, a participant develops ‘moderate’ COVID-19, then they are then randomised to either selinexor or placebo, and if at any stage after enrolling the participant develops ‘severe’ COVID-19 they are then randomised to either lenzilumab or placebo.
Importantly, participants enrolling into the trial can directly enter any of the four interventions if they meet the appropriate entry criteria.

Efficacy
Statistical methods / analysis
By employing an Bayesian approach for directly inferring the probabilities of efficacy for each of the interventions proposed, the trial sample size is not required to be fixed in advance, which is of benefit given there is limited information required to derive expected sample size. However, we have provided an indicative sample size that would be required to identify a treatment effect for each primary hypothesis if using a more conventional, non-Bayesian approach. The expected sample sizes for each treatment arm (1:1 randomisation) are provided in the summary table and were calculated for 90% power and a 5% two-sided level of significance
