 standby and retention samples [Regulatives / Guidelines]

Hello,

What will be the number of standby samples in a Bioequivalence study?
or what will be the percentage of standby samples to the total sample size?

Thank you,
Best Regards,

Dear Zeynep,

1. What do you call "standby samples" ?
2. For which authority / region ?

Dear Ohlbe,

Standby samples are the reserve samples.
I am asking for TR MOH but we follow primarily EMA and/or FDA guidelines.

Best Regards

 Reserve samples?

Merhaba Zeynep,

» Standby samples are the reserve samples.

Still not clear what you mean by that. Once you dosed a subject, you have to analyze the samples.

I am not qualified as a mind reader, but I think what was meant was something like spare subjects / standby subjects?

I could be wrong, but...

Dear ElMAestro,

Dunno, as retention samples (in the initial title of the thread) is the FDA terminology for investigational products (test article in FDA-speak) to be kept at the site after the trial.

Dear zeynep

For USFDA: Retention samples (Investigational medicinal product Test & Reference)
The quantity of reserve samples should be sufficient to permit the Agency to perform five times all of the release tests required in the application or supplemental application.For solid oral dosage forms (e.g., tablets, capsules), an upper limit of 300 units each for the test article and reference standard can be considered sufficient to meet the five times quantity.

Thanks

Ajit Thorat
