Bioequivalence and Bioavailability Forum

Dear All,
This is my first post on this forum. Please ignore any mistake.
In 2016, we did BE study of Lenalidomide 25 mg capsule for EMA submission.

Enrolled N =54
Completed N =52

Now are planning to conduct another BE study with same Test formulation (used in EMA) for ANVISA.

Below are the EMA study results.

1. Cmax
T/R 104.13
CI: 97.89-110.77
CV: 18.97
Power: 99.99

2. AUCo-t
T/R 102.20
CI: 100.51- 103.92
CV: 5.08
Power:100

My question is can we proceed with sample size i.e. 54 or should re-calculate sample size based on EMA study results?

T/R- 105%
Power- 90%
CV- Approx. 19%

What could be the right approach for sample size calculation for ANVISA submission study?
