More idiocy from venture capitalists. Even the morons at Pfizer walked away from this dog. You do not inhale insulin.
Aside from its ridiculously short half life, insulin has profound effects on respiratory tissue, which is only specialized for the exchange of O2 and CO2.
Many of these effect lead to hyperplasia of respiratory and smooth muscle cells in the lung.
Can you say "a lead-in to chronic obstructive pulmonary disease"?
I thought you could.
