"It is quite possible that whatever federal related grants processes there are, are midstream, and not appearing as yet." And I suppose that search might be unproductive because the funds are being sought by someone other than IPIX itself. Does BARDA fund this kind of research? By which I mean research undertaken by academic type institutions/RBLs. When BARDA's name comes up it seems to be consistently in the context of an actual drug company.
Edit: Perhaps Brilacidin might provide search returns where IPIX wouldn't?
