 In vitro binding study for sevelamer carbonate for Europe submission

Dear Divyen,
Thank you very much for your kind support..but still I want some clarity.

❝ Kindly refer your own post Sevelamer Carbonate In vitro binding study for EMA submission (Post#22597).


yes it's my Post..but still not getting any clearity about this...all PAR and guidance documents are available as per USFDA guidance..as Europe guidance is different for sevelamer carbonate..and they didn't accept USFDA guidance documents.. regulatory didn't accept our study which we were performed based on USFDA guidance ..so we have to perform the same study again as per Europe guidance ..so before starting the study i want to clear about the acceptance limit.

❝ Kindly refer Renvela CHMP ASSESSMENT REPORT


they given the reference of following of guidance documents of Europe:: Guideline for locally applied , locally acting product in Gestrointestinal trac(CPMP/EWP/239/95Rev.1,Cor.1*) and this guidance documents given the acceptance limit as +- 10percentage..

The CHMP assessment which you have shared is also published in the year 2009..

Thanks in advance....

Regards,
jansari...

Read the sentence again: In vitro similarity should be assessed with a ±10% acceptance range, unless otherwise justified.

Kindly refer Calcium acetate USFDA PSG.

we were already given justification based on this sentence.and explain that our study is passing within T/R ratio as per acceptance limit 0.9 to 1.1...but they are not accepting the same and again raised the queries....so now we are repeating the same study ,.
can I have your mail ID ?so I can detailed out the study detail which results we obtained in the study..and what exactly regulatory asked?

So you are aware about the acceptance limit. Currently what I am able to understand is that you are referring term regulatory for your company's regulatory team and not the authority's team. If it's authority's team- you are already having your answers.

❝ can I have your mail ID ?so I can detailed out the study detail which results we obtained in the study..and what exactly regulatory asked?


You can contact me via contact form in users section but your mail is is not registered, so i am not able to contact you through same medium.
