Hi Helmut,

Revisitng again this discussion, I want your suggestion on one scenario.

For one dose duration response study we have calculated ED50 and Emax by population model using Phoenix® NLME™ and we got below results.

ED50 : 120
Emax : -35

On other hand, using PPHARM software the values are as below,

ED50 : 50
Emax : -26

As you can see the difference is very big.

Now what you suggest, Should we go with Phoenix® NLME™ or PPHARM values ?

If we submit Phoenix NLME results to FDA, will be there any query from FDA as they are using PPHARM software ?

Please let us know your views.

Many thanks,
Dr. G C Patel
