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 2) is evaluating the effect of interferon-alpha on the incidence of COVID-19 infection in cancer patients with confirmed exposure to COVID-19 virus. 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 have had recent exposure to a known COVID-19 case Study details Participants in this study arm are randomly allocated (by chance) to one of two groups. One group will receive daily interferon-alpha intransal spray for 7 days while the other group will receive a daily placebo intranasal spray for 7 days Participants will be followed for 28 days for incidence of COVID-19 and other respiratory infections. 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.

Interventions

ARM 2 - Post Exposure Prophylaxis Drug: IFN-a Dose: 1,000,000 IU/Daily Duration: 7 days Mode: Intranasal spray (self administered) Adherence: drug return logs and 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

ARM 2 - Post Exposure Prophylaxis Drug: IFN-a Dose: 1,000,000 IU/Daily Duration: 7 days Mode: Intranasal spray (self administered) Adherence: drug return logs and 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.
