Best Practices in Modeling and Simulation Why do we need? Industry example. Wonkyung Byon Pfizer Global Clinical Pharmacology. Best Practices in M&S. Great idea! …….well, why do we need any guidance on Pop PK modeling???.

Best Practices inModeling and SimulationWhy do we need? Industry example Wonkyung Byon Pfizer Global Clinical Pharmacology
Best Practices in M&S Great idea! …….well, why do we need any guidance on Pop PK modeling??? Hi Won, we need to develop an internal pop PK guidance…. and you are the chair!
Best Practices in M&S Pharmacometrics/MBDD
Best Practices in M&S Pharmacometric analyses • Six-fold increase in the number of New Drug Applications that include pharmacometric analyses over a recent 9-year span (from 2000 through 2008) [Lee, J.Y. et al. Clin. Pharmacokinet. 2011] • Enhanced knowledge management and decision-making through model-based drug development [FDA Critical Path 2004]
Best Practices in M&S Objectives? Assumptions? Communications?
Best Practices in M&S Best Practices/Guidance… Why? Pharmacometrics = Evolving and interdisciplinary science Pharma industry = GLP,GCP,GMP
Best Practices in M&S Good “Modeling” Practice Benefit Risk “One size fits all.” Soon to be outdated • Increased consistency • High quality output • Greater efficiency • Training
Best Practices in M&S FDA/EMA Guidance For Industry • Population Pharmacokinetics • Guideline on reporting the results of Pop PK analyses • Exposure-Response Relationships • End-of-Phase 2A Meetings • Pharmacokinetics and pharmacodynamics in the development of antibacterial medicinal products
Best Practices in M&S Recent Publications • Fundamentals of population pharmacokinetic modelling: modelling and software/validation methods [Clin Pharmacokinet. 2012;51(8):515-25/51(9):573-90] • Basic Concepts in Population Modeling, Simulation, and Model-Based Drug Development—Part 1/ Part 2: Introduction to Pharmacokinetic Modeling Methods [CPT: PSP. (2012) 1, e6 / 2: e38] • White Paper: Landscape on Technical and Conceptual Requirements and Competence Framework in Drug/Disease Modeling and Simulation [CPT: PSP. (2013) 2: e40]
(iii) An update to the current regulatory guidance on dose ranging/finding (see also BOS2 paper) will be debated. (iv) M&S methodology and reporting standards and good practice documents are required (see also BOS4 paper). This will be an industry-led initiative in the first instance, though regulators wish to be involved early in the discussion with the ultimate objective to develop guidance documents.
