This novel approach seems like it could be highly effective in humans and doesn't require mRNA therapeutics or the use of a spike protein to initiate an immune system reaction. I'd be interested to see how this treatment evolves. "[The decoy] is a version of ACE2, the surface protein to which the virus attaches, which, unlike the natural, cell-bound version, is untethered from the cell surface. The free-floating decoy binds to the virus by its spikes so that it can no longer attach to ACE2 on cells in airways. Unlike the monoclonal antibodies, which are shaped to interfere with a certain spike shape, the decoy mimics the spike’s main target, and the virus cannot easily evolve away from binding to ACE2 and still invade cells."
