Dear All, As per Draft Guidance on Warfarin Sodium bioequivalence criteria for NTID as
Thanks in advanced.

Hi Biostats, your understanding of 1 & 2 is correct. Don’t forget #3! ❝ Please guide me to understand the bioequivalence criteria of NTI drugs. Can you be more specific? — Diftor heh smusma 🖖🏼 Довге життя Україна! _{} Helmut Schütz The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes

Thanks Sir, Is it mandatory to check  point estimate of the Test/Reference geometric mean ratio must fall within 80.00  125.00%? Edit: Full quote removed. Please delete everything from the text of the original poster which is not necessary in understanding your answer; see also this post #5! [Helmut]

Hi Biostats ❝ Is it mandatory to check  point estimate of the Test/Reference geometric mean ratio must fall within 80.00  125.00%? See your condition #2 and the guidance Every study should pass the scaled average bioequivalence limits and also regular unscaled bioequivalence limits of 80.00–125.00%. What do you think where the GMR lies if a study passes ABE? It is only nice to know (unless you are concerned about this discussion). If a study fails ABE, the location of the GMR is even less relevant. Hence, the FDA does not ask for it. — Diftor heh smusma 🖖🏼 Довге життя Україна! _{} Helmut Schütz The quality of responses received is directly proportional to the quality of the question asked. 🚮 Science Quotes

Dear All, Greetings !! FDA recommends not to round off the decimal places for confidence intervals. So for NTI drugs, the Swt, Swr and 95% upper bound and point estimate should be presented upto 2 decimal places without rounding off. If for Cmax, the 95% upper bound value is 0.0025 and if presented as 0.00, will the study can be considered as pass? For analysis in SAS, should we present the values in 2 decimals or 4 decimals without rounding off? As in above criteria, if we present the data in 2 decimal places, the study is pass. Please guide. Thanks
