Adam Feuerstein schools the Generex (OTCQB:GNBT) folks on what a "Treatment IND" really means, quoting chapter and verse from the FDA. The company's fans have made much of that designation for its flagship buccal insulin product. As has the company's CEO - but that link shows her making statements at investor conferences which are, on the face of them, in flat contradiction to the FDA's own understanding of such matters.
The article's worth reading even if you don't give two hoots about Generex, since it'll give you an understanding of what it means (and doesn't mean) when a company has a product designated for "compassionate use". It can also give you an understanding of what it means when a company misrepresents that status, but I think a lot of people here already know what that must mean. . .
