a 12 week trial for Rett - would be sufficient enough if you were to check for a 50% responder rate for improvement of seizures.

Look at the most recent phase 3 trials for Briviact, Vimpat, Aptiom, etc - all were a 12 week period before open phase study began.

If the Rett trial is to show clinically significant reduction of seizures from baseline - 12 weeks is sufficient, in my opinion.
