Challenges today: Targeting innovative therapies at appropriate patients Post-approval ‘market’ population Complexity & comorbidities • Patient populations vary greatly within disease groups, and this diversity is not always reflected in controlled clinical trials • Innovative therapies should be assessed in representative sub-groups before implementation in diverse populations • Understanding and targeting patients at greatest risk is necessary to reduce overall burden of disease most efficiently www. tri-london. ac. uk Pre-market population Disease specificity

Challenges today: Understanding the patient perspective and its rise up the agenda • Systematically recording and evaluating patient experiences is key when assessing quality of healthcare – Patients views of their own health measured using PROMs are important treatment effects and complement conventional clinical endpoints • Internet and other media have increased number of information sources for patients – Patients are aware of competing anticoagulant therapies and look beyond clinical trials for information • The patient ‘vote’ is increasingly important – Their views and views of their representatives (patient groups) need to be listened to PROM = Patient-reported outcome measure www. tri-london. ac. uk

Challenges today: Reducing disease burden whilst ensuring innovations represent value • Contemporary drug approvals

Challenges today: Reducing disease burden whilst ensuring innovations represent value • Contemporary drug approvals conditional upon validation of cost-effectiveness and budget impact models • Set the goal as value for patients, not equity, volume, convenience, or cost containment Outcomes × Safety × Experience Value = Cost • Outcomes are the full set of patient health outcomes over the care cycle • Costs are total costs for the care of the patient’s condition, not just the costs borne by a single provider www. tri-london. ac. uk Porter ME.
