Study type
Description of intervention(s) / exposure
ARM 3 - Moderate COVID-19 infection
Drug: Selinexor
Dose: 20mg 3x weekly
Duration: 14 days
Mode: oral - self administered tablet
adherence: supervised administration while inpatient. self 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.

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

Brief summary
A multi-centre Australian trial with four arms aims to evaluate several different immune modulating drugs for prevention and treatment of COVID-19 specifically in the cancer population. This study arm (arm 3) is evaluating the effect of Selinexor on the incidence of COVID-19 infection in cancer patients with moderate COVID-19 infection.

Who is it for?
You may be eligible to join this study arm if you are aged 18 and above, have any haematological or solid tumour, currently receiving cancer-related treatment, and are hospitalised with a moderate COVID-19 infection

Study details
Participants in this study arm are randomly allocated (by chance) to one of two groups. One group will receive oral Selinexor 3 times a week for 2 weeks while the other group will receive oral placebo 3 times a week for 2 weeks

Participants will be followed for 60 days to assess effectiveness and safety.

This study is one arm of a four arm, sequential multiple assignment randomisation trial where participants may become eligible and transition to different arms and treatments if they become exposed to COVID-19 or are hospitalised with an active moderate/severe COVID-19 infection.

It is hoped this research will provide insight into the best practice for prevention and treatment COVID-19 in cancer patients as emerging standard of care measures are not always suitable to this especially vulnerable population.
