TLR 7/9 http://www.dynavax.com <- well, according to a reuters article they will either have outlicensed their HCB vaccine soon or need some kind of (probably?) debt financing to commercialize it & finance their IO-program http://checkmatepharma.com <- private company http://www.iderapharma.com <- have not checked financing structure yet http://www.mologen.com <- personally, I really do not like their financing structure
(certainly not a complete list, but these should be the more known ones)
