» "A multiple dose study is needed unless a single dose study has been performed with the highest strength which has demonstrated that the mean AUC(0-τ) after the first dose covers more than 90% of mean AUC(0-∞) for both test and reference, and consequently a low extent of accumulation is expected".

Dear Mahesh,

You can consider "first dose" as a "single dose" study.

For MR products in EMEA, first perform pivotal BE study under fasting state and evalaute the results. If AUC0-t>0.9*AUCinf, you need not to go ahead for steady state BE study. BE under steady state is required when drug accumulates in body. If AUC0-t> 0.9*AUCinf is achieved after signle dose administration, normally, there would not be accumulation.

Hope this info would be helpful.

Regards,
Samaya.
