 Test samples expired for FED study [Regulatives / Guidelines]

Hello,

We have conducted Fasting BE study for Pantoprazole Sodium delayed release tablets from CRO.

As we are filing products in regulated market we have to performed Fed study as per EMEA & FDA guidelines.

Now problem is our Test samples are expired but RLD expiry renaming for next 8 months.

How can we conduct fed study. What are the challenges we can face after filing.

Hi Taiyab,

» […] is it acceptable fast and fed study performed on different batch of test product.

Why not?

Thank you everyone for your kind comments.

We will do fed study on different batch of test sample for Generic filing.

Can we expect any query on authority or specific requirement, we need to met before study initiation.

In my opinion, it's important only to send a justification letter (considering expiry date of the Fasting condition batches) following the Fed condition BE reports in order to avoid further authority concerns.

Hi All,

Why send a justification which is not needed?

It is nothing against to use a different batch's for different studies for the the same drug.

Best regards,

Cheers,

I agree with you. It was just a suggestion based on our previous experience in Brazil :-|. Sometimes we need to explain the inexplicable to health authority to avoid delays in the dossier review :-D

The use of a different batch in the fed study as asked above from taiyab.jameel could be better as you can prove batches therpeutic equivalence consistency via in vivo studies.

On the contrary, in the case of additional strength biowaiver, it is a must to use the same biobatch for which the therpeutic equivalence was proven before via in vivo BE study.

Best regards,

Cheers,

Retest, extend the shelf life if within specs, release for CT?

Pass or fail!

Right, this is exactly what is also done in phase III trials. But if you use another Test batch you can simply explain this in the clinical overview module 2.5 of the dossier.

Kind regards and have a nice day
