If you read the article again,it says they just finished Phase II so they haven't started the Phase III trials yet.As a MannKind shareholder the last paragraph was encouraging...

"As for the success of oral insulin, we remain a little skeptical. It might work well for folks who don’t need precise doses. But for those who do, this oral insulin is currently being used in a basal fashion, along with injections (or a pump) to cover meal boluses — which is a bit of a letdown. Hopefully more refinements will be made before this pill comes to market."
