in vitro study with the nasogastric tube, CI [Regulatives / Guidelines]
Please find the link for summary tables for in vitro feeding tube testing by FDA. (https://www.fda.gov/media/98853/download)
Also find the testing discussion by FDA in workshop - Advancing Innovative Science in Generic Drug Development Workshop
September 29 & 30, 2020 at https://sbiaevents.com/innov2020/. Kindly see the presentation titled D2S16- tyner and D2S17-Kapoor. They are focusing on %Recovery and I am not able to find weather 90%CI criteria will be applicable or not.
Hope it helps you.
