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!
