 If we have any methods to widen CI in parallel design with high variance drug? [RSABE / ABEL]

Dear all,

Recently I meet a problem about sample size of high variance drug, normally, we will design a repeated cross-over trial for this kind of drug. But this time it is designed as a parallel study due to some reasons. But the sample size is too much based on 80%-125% BE CI. So my quesion is if we have any method to widen the CI like RSABE in cross-over study? Thank you very mcuh.:-D

Sincerely,
libaiyi

Hi libaiyi,

» (...) So my quesion is if we have any method to widen the CI like RSABE in cross-over study?

I don't think there is any authority generally willing to widen the acceptance range in parallel trials involving humans (they'd perhaps do it if you were studying pMDI's in vitro etc).

Pass or fail!
