Is a Clinical Trial With a Non‐Bioequivalent Batch Necessary? The Critical Role of Intrasubject Variability in Olaparib Formulation Bridging by PBPK

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Although physiologically based pharmacokinetic (PBPK) modeling is increasingly being used to support oral drug formulation bridging, the acceptance by regulatory agencies is low. One of the primary concerns is the absence of clinical pharmacokinetic (PK) data from a non‐bioequivalent (non‐BE) batch during model validation.

A Review of Virtual Twins in Physiologically‐Based Pharmacokinetic Modeling and Simulation

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The novel application of Virtual Twins (VT) in PBPK (VT‐PBPK) presents the opportunity to advance precision dosing and accelerate the shift from one‐size‐fits‐all to targeted, individualized treatments. This review aims to: (1) critically evaluate existing research on the use of VTs in PBPK, (2) develop a conceptual definition of VT‐PBPK, (3) describe ...

Assessing the similarity of dose response and target doses in two non-overlapping subgroups [PDF]

open access: yes, 2017
We consider two problems that are attracting increasing attention in clinical dose finding studies. First, we assess the similarity of two non-linear regression models for two non-overlapping subgroups of patients over a restricted covariate space.
