RegisterDifferent power of AUC vs. Cmax at stage I - continuation rules [Two-Stage / GS Designs]
Hi all,
I would like to raise a scenario following stage I results with Potvin C:
If, hypothetically, our results at stage I would have had good ratio, and failed to meet 94.12% CI BE criteria at stage I for both Cmax and AUC.
The power analysis would have shown results higher than 80% for AUC, and lower than 80% for Cmax. Based on Cmax, we could continue to stage II. In that case - what would be the practice for AUC? I would assume it would have been calculated also for stage II. How should this be covered in the protocol?
Would appreciate your input.
Many thanks,
Nisha
