Printedonacid-freepaper SpringerispartofSpringerScienceþBusinessMedia(www.springer.com) Preface During the seven years following the inaugural publication of Simulation for Designing Clinical Trials: A Pharmacokinetic-Pharmacodynamic Modeling Per- spective, acceptance and application of clinical trials modeling and simulation (M&S)indrugdevelopmentandregulationhavegreatlyexpanded.Biopharmaceu- ticalcompanieshaveemployedM&Sinallphasesofdrugdevelopmenttoachieve greater efficiency and dosage optimization. The food and Drug Administration’s (FDA)visionary2004CriticalPathInitiativehighlightedclinicaltrialsimulations (CTS) in “model based drug development” to facilitate efficient development. In the meantime,FDA and the EuropeanMedicines Agencyhave encouraged use of CTSviaregulatoryguidances,andhaveemployedM&Sforlabelingandapproval decisions.Onthebackdropofthesedevelopments,thetitleofthiseditionhasbeen chosentoreflecthowCTSisbeingemployedindrugdevelopmentandregulation, andtrendsforexpandedapplicationsinthefuture. Thiseditionincludesupdates,newuses,andissuesconcerningCTS,alongwith casestudiesonhowclinicaltrialsimulationsarebeingappliedinvarioustherapeutic andapplicationareas.Importantly,thebookexpandsontheuseofCTSforinforming decisionsduringdrugdevelopmentandregulatoryreview.Eachchapterauthorwas selectedonthebasisofdemonstratedexpertiseinstate-of-the-artapplicationofCTS. Editors’opinionsonadvancesandimpactfultrendsofCTSinmodel-baseddrug development and regulation are introduced (Chap. 1). Regulatory agencies have been proactive in promotinguse of CTS, and Chaps. 2 and 3 present the perspec- tives and experiences of FDA and European regulatory agencies by the authors workingintheseagencies. Methods to facilitate decision making in drug development are discussed by pointingouttheimportanceofassessinguncertaintyofpredictedtrialperformance andoutcomesinplanningofprospectivetrials(Chap.4).Forquantitativedecision- making,constructingclinicalutilitycurves(Chap.5)canbeuseful.Adaptivetrial design has gained attention as a method for more efficient and informative drug development,anditscurrentstatusisreviewedinChap.6.Chapter7illustratesan M&S application case where personnel from biostatistics, clinical research and clinicalPK-PDcouldcollaboratetomakebetterinformeddecisionsontrialdesigns v vi Preface throughoutaclinicaldevelopment.Chapter8illustrateshowpreclinicaldatacanbe integrated in a model-based drug development program to optimize early stage development,usingCTStosimulateafirst-in-humanstudy. Many successful cases employing CTS in guiding drug development decisions havebeenpublishedintheliteratureandpresentedatconferences.Representative casesinselectedtherapeuticareasprovideageneralbackgroundonhowtobenefi- ciallyemployCTS, followed bythe authors’ experiences.Applications ofCTSin eight therapeutic areas (Chaps. 9–16) are covered: diabetes, cardiovascular dis- eases, viral infections, antimicrobial chemotherapy, cancer, hematology, anxiety disorder,andepilepsy. Chapter 17 discusses how CTS can be used in therapeutic biologics develop- ment. Designing ethical and informative pediatric studies requires integrating all available information, while gaining pediatric specific knowledge from a limited numberofobservations.ThefactorstoconsiderinusingCTSforpediatricsstudies aredescribedinChap.18. Thefinalsectionofthebookincludeschaptersthatdescribeevolvingmethodol- ogiesinCTS.Theimportanceofincorporationofdiseaseprogressionelementsin CTSmodelsisemphasized,especiallywhentheevolutionofdiseaseduringatrial is considered in evaluating treatment effects attributable to the drug (Chap. 19). The systems biology approach incorporates high resolution mechanistic models, involving fundamental dynamics of cells and biological signaling systems. Using suchmodels,predictionsofclinicalresponsesmayultimatelybemadebysimula- tions (Chap. 20). Recent advances in in vitro, ex vivo, and in silico methods to provideinputvariableinformationhavesignificantlyincreasedtheapplicabilityof thetraditionalwhole-bodyphysiology-basedpharmacokineticmodelingapproach, and its practical implementation is reviewed in the Chap. 21. Simulating drug responses in a virtual patient population and how to collect and utilize datasets forconstructionofcovariatedistributionmodelsarepresented(Chap.22).
