Just as a side note with regards to Auris Medical being as you say the only "player in the game" I don't agree.
I actually bought the article on SF0034 which was published in the Journal of Neuroscience, June 10, 2015, and I read it many times with a scientific perspective. And btw I encourage you to do so as well if you haven't done so.
Kerrisdale Capital has a strong opinion on the value of Scifluor as a future treatment, but they failed to understand the scientific evidence and facts proven "in vivo" with the Scifluor experiment on animal models. Of course by no means I admit these experiments guarantee any success in human trials, but Kerrisdale Capital state their arguments with a little excessive authority in my perspective. They seem to jump into quick conlusions without supporting their arguments with scientific evidence. Please read this article and you will understand my point. I simply emphasize the idea that there is no reason yet to put aside the potential of SF0034.
Food for thought.
