Clinical Trial 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.

ARM 1 is evaluating the effect of interferon-alpha (vs placebo) on the incidence of COVID-19 infection in cancer patients with no COVID-19 infection or no known COVID-19 positive contacts.

ARM 2 is evaluating the effect of interferon-alpha (vs placebo) on the incidence of COVID-19 infection in cancer patients with confirmed exposure to COVID-19 virus.

ARM 3 is evaluating the effect of Selinexor (vs placebo) on the incidence of COVID-19 infection in cancer patients with moderate COVID-19 infection.

ARM 4 is evaluating the effect of Lenzilumab (vs placebo) on the treatment of COVID-19 infection in cancer patients with severe COVID-19 infection.

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 of COVID-19 in cancer patients as emerging standard of care measures are not always suitable to this especially vulnerable population.
