1 Canada s Rare Disease Strategy: Pathway to Timely Sustainable Access CADTH Conference Durhane Wong-Rieger, PhD Canadian Organization for Rare Disorders President & CEO

2 Getting to Sustainable Access What is current status of access to drugs for rare diseases in Canada? What is desirable for patients, prescribers, payers, and producers? What are emerging international best practices? What are the opportunities with Health Canada, CADTH, pcpa, private and public payers? What are the obstacles? What is a sustainable and workable way forward for Canada? 2

3 Rare Diseases: Unaddressed Public Health Issue But Canada s federation makes national approach a challenge!

4 # Canadians with Common vs. Rare Diseases 3.5 Milions Affected M 2.4 M 1.4 M 2.8 M Cancer Diabetes Heart disease Rare Diseases

5 5 Key Goals of Canada s Rare Disease Strategy 1. Improving early detection and prevention 2. Providing timely, equitable and evidence-informed care 3. Enhancing community support 4. Providing sustainable access to promising therapies 5. Promoting innovative research Canada Rare Disease Strategy Opportunities for Access Feb 2016

6 Rare Disease Strategy Supports Transforming Therapies into Improved Care Studies designed to promote understanding of effectiveness of interventions in real-world systems of care Range of therapies and health services as co-interventions, such as diet therapy, physiotherapy, family support and counseling, telehealth, and interdisciplinary team care, specialized treatment centers, and care coordination Identify long-term impacts of care, including potential adverse effects Determine how real patients and disease characteristics influences treatment effectiveness; account for clinical heterogeneity 6

7 7 Traditional HTA Limits Orphan Drug Access HTA OFTEN same as for common drugs RCTs = small samples, short timeframes, surrogate markers High $ development, small population = High $/patient Cost-utility: $/QALY below theoretical $50k threshold Small # = Low budget impact HTA recommends no to most drugs for rare disorders Private drugs plans usually cover (but some do not) Public drug plans usually adopt HTA recommendations HTA limits access in some European countries Half of all orphan drugs evaluated have been rejected by one or more HTA bodies in the UK. Where Cost-Effectiveness NOT norm, reimbursement varies; best = 80% to 100% funding

12 Evidence about drug Balancing Timely Access and Certainty of Benefits/Risks We want certainty about safety and benefits of drugs We need timely access to drugs for unmet & urgent needs Time 12

13 Increasing Number of Patients Adaptive pathways Aim to provide timely access to new medicines by balancing medical need with evolving information on the benefit risk FULL APPROVAL Intensive monitoring of patients Additional indication(s) Intensive monitoring of patients Initial approval of niche indication Time 13

14 Key Obstacles MAPPs: perception that earlier access for (some) patients with limited data could lead to safety problems and undermine public trust More drugs for smaller patient subpopulations => not sustainable; unwillingness to pay for early access with limited data Need tools to limit access to approved subset (avoid off- label use) Practicalities and cost of implementing flexible or outcome based reimbursement strategies Extra work for regulators, HTA bodies, and payer due to repeat cycles of assessment and negotiations with sponsors Need capacity building and support for all stakeholders in order to fully integrate contribution of patients and patient organizations across drug life cycle

15 The real challenges seem to be more associated with efficacy than with safety Major reasons for late-stage failures (n = 73) Comment Efficacy (vs. placebo) 50% 50% Efficacy is the most frequent reason for failures in late-stage development This is not related to limited Safety (vs. placebo) Confirmation of early safety concerns Non classifiable 8% 23% 31% as 22 examples of top-10 pharmacos reveal Efficacy failures are largely influenced/ enhanced by Novelty of mechanism of action (MoA) Lack of differentiation Efficacy Safety 3% 16% 19% Objectivity of clinical trial endpoint Modality Novel MoA bears double failure risk Less objective endpoints (e.g. PROs) on average lead to ~10% increased failure risk 15

16 Lifecycle Approach with Patient Input & Post-Market/Real World Data Payer: Budget Impact; Access Criteria; R-W Data Collection Researcher/Clini cian: Disease Knowledge; Drug Discovery; Treatment Guidelines Patient Input HTA: Comparison Benefits, Risks, Cost w/alternatives; Place in Therapy Company: Clinical Trials & Outcome Measures; biomedical, clinical, PROs, Real-World Impact Regulator: Approval on Benefits-Risks- Uncertainties; Use & Real- World Monitoring 16
