 Biowaiver for Lower Strength [Regulatives / Guidelines]

Dear All,

I'd like to seek some advice regarding a specific requirement in the EMA BE guidelines biowaiver:

the amount of the active substance(s) is less than 5 % of the tablet core weight, the weight of the capsule content

Is this criteria applicable for both the BE strength and the lower strength aimed for biowaiver? Can a BE biowaiver for the lower strength be considered if only the lower strength meets this <5% API of tablet core weight requirement? The higher strength has 5.88% of API content per tablet core weight and passed BE. All other biowaiver requirements have been met.

Appreciate any advise i can get on this matter. Thank you very much

Dear vandee,

❝ Can a BE biowaiver for the lower strength be considered if only the lower strength meets this <5% API of tablet core weight requirement? The higher strength has 5.88% of API content per tablet core weight and passed BE.


The 5% criterion applies to both strengths, lower and higher.

Ohlbe

 Biowaiver for Lower Strength

Hi Vandee & Ohlbe,

As Ohlbe said, according to EMA for an additional strength biowaiver, the Amount of API(s) must be < 5% of tablet (capsule) core weight for both strengths, the BE strength and the biowaiver one.
Moreover, the Amounts of excipients are the same per strength or Only the amount of a filler is changed to account for changes in API weight.

The FDA doesn't consider this 5% rule and the requirements for an additional strength biowaiver are as following:
  • Total weight of dosage form nearly the same for all strengths
  • Same inactive ingredients in each strength
  • Change in strength obtained by varying active and one or more inactive ingredients
Both EMA & FDA are asking for the Similarity of dissolution characteristics of the biowaiver strength to the strength for which bioequivalence has been demonstrated in vivo.


I hope this could help.

Cheers,
Osama

Dear Osama,
This is indeed very helpful. I will justify my biowaiver using the USFDA approach in hopes that regulators here (ASEAN) will accept. Thank you very much for your advise.
