Dear all,

What information may be needed to extrapolate linearity for the oral solution dosage form.

Innovator has developed tablet and has established linearity in the dose range e.g. 10-200mg (oral) and 2-10 mg (IV).
Generic oral solution has been available in the strength of 5mg/5ml and 25 mg/5ml.

If we develop oral solution which is Q1 same and Q2 similar (no excipient affecting GI motility/similar to generic). How can we prove linearity for 5mg/5ml strength and get biowaiver?

Drug is BCS class 3

Has been used in the general population for more than 10 years and the submission is for Europe.

Regards,
PJS
