Hi dshah,
Why don’t you simply tell us that the drug is rivaroxaban?
Fine. Though there is no product-specific guidance for rivaroxaban publishd by the EMA, most people would consider it an NTID indeed. Following the logic of other NTID-guidances that would mean acceptance limits of 80.00–125.00% for Cmax and 90.00–111.11% for AUC. In rare cases the limits of Cmax have to narrowed as well. Up to you to provide a justification.
Biowaivers for NTIDs are not acceptable. BE-Guideline APPENDIX III:
❝ We are working on a NTI drug with high variability for which different dissolution media is recommended by USFDA.
❝ For BE study as per USFDA- a fasting and fed study for highest strength is recommended.
Why don’t you simply tell us that the drug is rivaroxaban?
❝ For EMA- A fed study on highest strength and a fasting study on another mid strength is concluded based on guideline.

❝ For waiver request for other strength we need acceptable in vitro dissolution testing of all strengths.
Biowaivers for NTIDs are not acceptable. BE-Guideline APPENDIX III:
Applying for a BCS-based biowaiver is restricted to highly soluble drug substances with known human absorption and considered not to have a narrow therapeutic index.
