 biobatch size and scale up [Regulatives / Guidelines]

Dear all,

I would kindly like to ask for your advice.

According to the CPMP/EWP/QWP/1401/98 Rev. 1/ Corr ** "In case of a production batch smaller than 100,000 units, a full production batch will be required."

If the biobatch is < 100,000 units, is scale-up allowed according to EU regulations?

Thank you,

Best regards,

Elena

 Type II Variation

Hi Elena,

❝ If the biobatch is < 100,000 units, is scale-up allowed according to EU regulations?


Do I get you right – you got the approval with a production batch which is <100,000 units and want to scale up? IMHO, this is a “Major Variation of Type II” as defined in 1234/2008/EC Article 2(3), which

[…] means a variation which is not an extension and which may have a significant impact on the quality, safety or efficacy of the medicinal product concerned.

If waiving criteria of the GL are not fulfilled, I would say you need another BE study.

 Type II Variation

Hi Helmut,

Thank you for your reply. This really helps.

We are still in developing phase and consider the size of the biobatch.

Just to be sure, if the biobatch is < 100,000 units and the scale-up is up to 10 fold, a type II Variation is needed, supported by a Bioequivalence study?

Kind regards,

Elena

 Type II Variation

Dear Elena
AFAIK if you conduct the BE study with a production scale batch of less than 100.000 then you will get a marketing authorisation for your product with a production scale of less than 100.000. Afterwards you can scale up up to 10 fold with a variation. The kind of variation (type Ia/b, II) depends on the complexity of the production and scale up process. A new BE must not be mandatory.
Kind regards
Dan

Kind regards and have a nice day

Dear all,

❝ A new BE must not be mandatory.


Well... I've heard of some dossiers where the French Agency made it a clear condition when granting a marketing authorisation.

Regulators are not too happy with applicants who think a little too obviously that they are stupid :-D. If you run your BE with a batch of 50,000 tablets and claim this will be your full industrial batch size, then come with a variation to increase the size to 500,000 without a new BE, you can expect some difficulties.

 Type II Variation

Dear Dr Dan,

Thank you for your response.

Reviewing the available literature I came across this presentation 3-2 Biobatch considerations for quality.
According the information on slide 4 "A biobatch of < 100,000 units may be accepted, but then no scale-up is allowed. This should be clearly indicated in reports for the product, as it affects allowable variations."

This information was the reason for the concern raised.

Could you please indicate a guideline/regulation which states that the scale up is possible even if the biobatch is < 100,000 units.

Kind regards,

Elena
