 BCS II waiver approach [Dissolution / BCS / IVIVC]

Dear All,

Drug compound is BCS-II [dosage form is solution filled in capsule], and objective is to formulate with Q1 & Q2 sameness to that of Reference. Since API is in solution state filled in capsule, its solubility/bioavailability is improved tremendously.

In the above scenario, can we consider for BCS based waiver approach ?

Dear yuvaneshwari,

I think you have answered your own question. If solubility is the limiting factor, and your product has an improved solubility compared to the reference, how could you justify any kind of biowaiver ?

In any case: BCS-based biowaivers are only possible for class I and III products. Not the slightest chance if you're dealing with class II or IV.

Thanks for your response. I was hoping to justify the waiver on the basis of sameness of finished test product against reference. I understand that criticality still remain since the molecule is BCS II drug. Thank you.
