The most important addition to the state of knowledge here is the timing of administration. It made no difference in people who did not need supplemental oxygen. That is helpful to clinicians wondering when to trigger it in the treatment protocol.
While it is always good to see good news, I don't understand the hype. Haven't there already been several apparently more effective interventions on which we're still waiting to see confirmatory data? Heparin, Avigan, famotidine, interferon? "Early outpatient" interferon in high-risk patients seems like a potentially efficacious and easy to administer intervention. I too would like to read a bit more current, reliably-interpreted information on the status of such investigations.
