Delcath treats their investors like a mushroom - We are kept in the dark and fed sh*t. That being said...
Delcath has a history of pulling the rabbit out of the hat when you least expect it. I have a hard time believing that they will just hang it up after all they have done to get their product to market. I know things don't look good, but what do we really know here? It is reasonable to assume that there are other actors unseen who are working on this.
