The integration of phase 1 pharmacokinetic data with nonclinical data from infection models, and the use of the Monte Carlo simulation, allowed us to construct doripenem dosing strategies for further clinical evaluation in phase 2 and 3 (...). When sufficient phase 2 pharmacokinetic data are available, it will be important to use these data to refine the current population pharmacokinetic model and subsequently make more accurate inferences about PK-PD target attainment in patient populations of interest.

- そして,
Although uncertainty in the estimation of typical values of pharmacokinetic parameter estimates or interindividual variability had little impact on PK-PD target attainment results, two notable and related limitations of these analyses were evident.

- つまり,phase 1 のデータを用いているので,例数が少ない,対象集団が均質すぎる,特に,腎機能のばらつきが小さい,ということ.
- 何を検討したかというと,
Sensitivity analyses, carried out to assess the magnitude of deviations in PK-PD target attainment for simulations based on the upper and lower confidence bounds versus those based on the central estimates for the pharmacokinetic parameters, failed to show a substantial impact of uncertainty in the estimation of pharmacokinetic parameter typical values or interindividual variabilities.
