CONFIDENTIAL Accelerating Drug Development through Drug & Companion Diagnostic Co-Development Mark Roberts PhD Director, Diagnostics Development Covance Central Laboratory Services

CONFIDENTIAL 22 Our Environment Today Pressured Cycle of Dependencies The pressures are the same across the marketplace… why are some companies succeeding while others continue to struggle?

CONFIDENTIAL 3 Drugs Don’t Work for all Patients Antidepressants Cancer Drugs Diabetes Drugs Arthritis Drugs Asthma Drugs Source : Personalized Medicine Coalition Estimated $350 billion wasted in 2011

CONFIDENTIAL 44 The Future Is ……… Personalized Medicine Providing  the right treatment  for the right person  at the right time  in the right dose

CONFIDENTIAL The New Drug Development Paradigm Personalized Medicine Companion Diagnostics are integral to the new Personalized Medicine paradigm Personalized Medicine Targeted Therapeutic Biomarker An “in vitro” device that provides information that is essential for the safe and effective use of a corresponding therapeutic product” Source : US Food & Drug Administration

CONFIDENTIAL 6 Many ‘Companion’ Diagnostics developed after a drug is on market Retrospective validation using banked samples: potential IRB / informed consent issues / new trial Drug manufacturer unlikely to change labeling unless required to do so by FDA : may consider extra testing / expense to be a detriment to clinical use 6 CDx: Historical Perspective

CONFIDENTIAL 7 Better understanding of the genetic and polypharmacy causes of adverse reaction Increasing utility of pre-dosing patient stratification through understanding of ‘pathway’ targets Targeted therapy improves clinical outcome –Enhanced safety profile : and reduced liability claims? –Enhanced therapeutic efficacy Enhanced healthcare economics 7 CDx: A New Perspective

CONFIDENTIAL 8 FDA :Drug & CDx Co-Development “In most circumstances, if use of an in vitro companion diagnostic device is essential for the safe and effective use of a therapeutic product, the IVD companion diagnostic device and therapeutic product should be approved or cleared contemporaneously by FDA for the use indicated in the therapeutic product labeling,”

CONFIDENTIAL Drug / CDx co-development successes Targets ALK mutation in NSCLC Occurs in 4% - 5% of patients Tumor shrinkage in 83% of ALK +ve patients (4-5% of NSCLC) Drug and CDx (Abbott) launched in 2011 Targets V600E mutated BRAF in advanced melanoma Occurs is ca. 60% of mm patients Drug and device approved together in 2011

CONFIDENTIAL 10 QUESTION: What role do you see CROs playing in the development of companion diagnostics over the coming years? Voice of the Client Survey : 2011

CONFIDENTIAL 11 Clients had not considered CROs role – Dx focused Clients continue to define their needs (lack clarity) Clients voiced the need for : –Capabilities: Fill the gap where clients lack ability or expertise –Flexibility: Resource flexibility under an outsource model –Integration: Providers able to integrate services are valuable –CDx vision & direction: Clients are struggling and need a partner with vision AND capabilities to guide their path forward Summary of VOC Feedback

CONFIDENTIAL TodayYesterday 12 Charting a New Model Diagnostic Devices CONFIDENTIAL Drugs & Biologics Diagnostic Devices The future of Healthcare will require a new mindset: Products and industries once considered separate and distinct move to integration Drugs & Biologics Integrated with Diagnostics

CONFIDENTIAL 13 Why Rx / CDx Co-Development? Potential to: enhance therapeutic efficacy increase safety & reduce risk Speed-up development process improve trial design increase commercial success improve trial design enhance safety profile enhance therapeutic efficacy accelerate trial outcome Increase commercial success

CONFIDENTIAL 14 Hurdles Under the New Model 14 Success Begins with the Right Partners

CONFIDENTIAL Global Diagnostics Market $ 44 billion in 2011 > 5% CAGR to $62 billion in 2016 Largest Players –Roche$ 7.4 billion –Siemens $ 5.2 billion –Danaher$ 4.4 billion –Abbott $ 4.3 billion

CONFIDENTIAL 16 Companion Diagnostics Market World Companion Diagnostics Market ($Billions) (incl. the sales of testing kits and testing service revenues). “Companion Diagnostics World Market ”, VisionGain (2011) CAGR 21.6%

CONFIDENTIAL Nature of Diagnostic Target (biomarker) Required Turn around Time of Result Channel to Market Economics 17 Considerations in Choice of Commercial Partner

CONFIDENTIAL Rx / CDx Co-Development Value for Stakeholders 18 Stake HolderBenefit BioPharma Companies Reduced Drug Development Costs Improved safety-efficacy profile of drug Increased cost effectiveness of drug Accelerated regulatory approval Competitive advantage (differentiated therapeutic) Rescued drugs Premium pricing for “targeted” drug Dx Companies New market opportunities Develop new partnership with Pharma companies Premium pricing for CDx Increase distribution of their product
