Sigh...this board is supposed to be for factual information, let's try to use the proper terms when we can.
Remdesivir is not approved for the treatment of any indication. It says so in the EUA.
The term "fast track" also has specific meaning. Remdesivir and many other potential COVID-19 therapies were granted Fast-Track when they submitted their INDs. That allows for faster review times and more ongoing communication with the FDA during the development process. That is separate from this EUA.
As an example of why this distinction is important, the EUA can and will eventually be rescinded. If remdesivir is not yet approved for any indication at that time, it will revert to only being available via clinical trials and compassionate use/expanded access programs.
This same thing happened during H1N1. Peramivir, promising new IV antiviral, not yet approved for any indication, was granted EUA in October of 2009 based on some preliminary data. That order was rescinded in June 2010 because the emergency was deemed over. It then took BioCryst, the makers of peramivir, until December 2014 to gain it's first FDA approval.
So yes, I feel it is important to use the correct terminology so as not to be misleading.
