Bioequivalence and Bioavailability Forum

Dear colleagues!

Although it may be not a good idea to use 'old' studies for a regulatory submission – since scientific progress may be pretty fast – the only national guideline mentioning an 'Expiry Date' for a BA/BE study comes from South Africa, which states at 3.10 (page 13):
'The bioavailability/bioequivalence study should have been completed not longer than five years prior to the date of submission.'
