Dear all,

In one of the full replicate study of NTID the results are as per below,

 Parameters   Swr    95%CI

LnCmax       0.04   0.0001

LnAUC0-t     0.07   -0.003

LnAUC0-inf   0.07   -0.004

The ABE results are as below,

 Parameters   T/R    90%CI-L    90%CI-U

LnCmax       97     95         99

LnAUC0-t     99     97         101

LnAUC0-inf   99     97         101

The point estimate is near to 100 and ABE is also within 80% to 125%.

But in SABE, the Cmax criteria is more than 0 i.e. 0.0001 which leads to bioinequivalence.

So can it be scientifically justified the 95%CI of Cmax value as its very borderline to 0 and T/R shows less difference between test and reference.

Thanks

-Jay
