Sometimes the brand name is different for different countries. I would bet that the trademarking of Immuvance and some of the other trademark names they submitted at the same time in January are for that reason. International brands, veterinary-specific brand names, and also indication-specific names. For instance it could be Vyrologix for HIV in the US and Immuvance overseas, then Levimmune for veterinary use.
No name, however, will be as good as my favorite drug name of all time for the treatment of prostrate (and ultimately urination) issues...Flomax
