Dear All,

We are developing Sapropterin dihydrochloride powder for oral solution,

We are going to file BCS based Bio-waiver approach using solubility, dissolution & composition similarity.

But for permeability study there is no literature support for human absolute bioavailability study or in-vitro permeability study of Sapropterin dihydrochloride. Whether USFDA accept our proposal without permeability study data ?

With regards
AB
