Amantadine for COVID-19 treatment (ACT) study: a randomized, double-blinded, placebo-controlled clinical trial.

Objectives: The COVID-19 pandemic has revealed a severe need for effective antiviral treatment. The objectives of this study were to assess if pre-emptive treatment with amantadine for COVID-19 in non-hospitalized persons ≥40 years or adults with comorbidities was able to prevent disease progression and hospitalization. Primary outcomes were clinical status on day 14.

[The antiviral targeting potential of viroporins].

Viroporins are ion channels found in many viruses, where they contribute to virus life cycle and thereby pathogenesis. Viroporin targeting is a known, yet largely unexplored, therapeutic strategy so far only used in Influenza A with the drugs amantadine and rimantadine. In this review, we seek to utilize the inhibition by amantadine of the viroporin Protein E in SARS-CoV-2 in an attempt to treat COVID-19 in its early stages.
