As their affiliation was PolyMedix at the time of the research, it follows that would be the commercial relationship disclosed. I wonder if the (F) indicates former? It wouldn't make sense to mention Cellceutix as they weren't involved in the research being presented.
Hopefully this abstract will lead to a peer reviewed journal article on Brilacidin for ocular pathogens.
As Abstracts and articles often take months or years to get presented and published, the companies involved may be gone, but the researchers still publish, especially if in academia.
The Brilacidin journal paper was an example, published in 2014, about a year after PolyMedix was gone.
