Chris,

MannKind did not do that survey,some group(I forget the name) apparently does these surveys every year at the American Diabetes Associations annual conference.Also when figuring the cost you should remember that with Afrezza you don't have to check your blood sugar as often,which is not cheap in itself....

The bottom line is always costs. Will patients get insurance coverage for Afresa?

We’re working with the reimbursement advisory panels to make sure we’re within 5% of the current costs of Humalog and Novolog — so people will get essentially the same reimbursement they get now. We believe that we’ll be covered by most mainstream health plans within six months of launch.

Don’t forget this also saves a lot of money because you don’t need nearly as many expensive test strips for fingersticks, by an order of magnitude. For Type 2s, maybe they’ll just need a fasting test once a week. If you’re Type 1, you will want to do a few more.
