Gilead Sciences – Remdesivir (severe)

Remdesivir, an antiviral drug that was initially developed for Ebola by the pharmaceutical company Gilead, has shown promise against COVID-19 [1, 2, 3]. It is an adenosine nucleotide analogue, which allows it to incorporate into viral RNA chains and cause premature termination of viral reproduction. It shows antiviral activity against filoviruses, paramyxoviruses, pneumoviruses, and pathogenic coronaviruses, including SARS-CoV and MERS-CoV [4].

Gilead has initiated a Phase 3 clinical trial of two remdesivir treatment regimens in 400 patients with severe COVID-19 [5] to evaluate the efficacy of remdesivir compared to the standard of care. Both primary and full results should be available in May 2020.
