Highly Variable Drug BE Justification [Regulatives / Guidelines]
Hi all,
Just want to know what your experience is on this matter.
The FDA stated that "Special Considerations: Applicants may consider using a reference-scaled average bioequivalence approach for x drug. If using this approach, the applicant should provide evidence of high variability (i.e., within-subject variability ≥30%) in bioequivalence parameters. Applicants who would like to use this approach are encouraged to submit a protocol for review by the Division of Bioequivalence in the Office of Generic Drugs."
The above implies that one can conduct replicate studies (RSABE) if he/she has supportive data (ISCV>=30%). What if one conducted pilot studies and found that the ISCV is like 28/29%? My concensus still would be to proceed with RSABE approach since the it is a mixed approach which allows both RSABE (if Ref SD<0.294) and ABE analysis (if Ref SD>0.294)
