The trouble is that the new medications probably don't work by the time you're in the ICU with Covid. I'm not sure it was tested with this one specifically, but at least one of the recently-approved medications was previously trialled on ICU patients and showed no benefit - they had to do another study giving it to people who hadn't been hospitalized yet to get any useful reduction in deaths, and there's some reason to think this is an inherent limitation of drugs that try and reduce viral replication. This study only seems to cover patients who haven't been hospitalized at the point when they start the treatment.
