Summary of "Application of Physiologically-Based Pharmacokinetic Modeling to Predict Pharmacokinetics in Healthy Japanese Subjects."

Pharmacokinetics (PK) in Japanese healthy subjects were simulated for nine compounds using physiologically based pharmacokinetic (PBPK) models parameterized with physicochemical properties, preclinical absorption, distribution, metabolism, and excretion (ADME) data, and clinical PK data from non-Japanese subjects. For each dosing regimen, 100 virtual trials were simulated and predicted/observed ratios for C and AUC were calculated. As qualification criteria, it was pre-specified that over 80% of simulated trials should demonstrate ratios to observed data ranging from 0.5 to 2.0. Across all compounds and dose regimens studied 93% of simulated C values in Japanese subjects fulfilled the criteria. Similarly for AUC, 77% of single dosing regimens and 100% of multiple dosing regimens fulfilled the criteria. In summary, mechanistically incorporating the appropriate ADME properties into PBPK models followed by qualification using non-Japanese clinical data can predict PK in Japanese population and lead to efficient trial design and conduct of Japanese Phase I studies.

Medical and Biotech [MESH] Definitions

The development and application of computational models of human pathophysiology that are individualized to patient-specific data.

The application of molecular biology to the answering of epidemiological questions. The examination of patterns of changes in DNA to implicate particular carcinogens and the use of molecular markers to predict which individuals are at highest risk for a disease are common examples.

Computer-based systems that enable management to interrogate the computer on an ad hoc basis for various kinds of information in the organization, which predict the effect of potential decisions.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
