0 Cost-Effectiveness of Fractional Flow Reserve-Guided Percutaneous Coronary Intervention in Patients with Stable Coronary Disease: Results from the FAME 2 trial William Fearon, Bernard De Bruyne, Nico Pijls, David Shilane, Derek Boothroyd, Pim Tonino, Emmanuele Barbato, Peter Juni, and Mark Hlatky on behalf of the FAME 2 Trial Investigators

1 Disclosure Statement of Financial Interest
Within the past 12 months, I or my spouse/partner have had a financial interest/arrangement or affiliation with the organization(s) listed below. Affiliation/Financial Relationship Company Grant/Research Support Consulting Fees/Honoraria Major Stock Shareholder/Equity Royalty Income Ownership/Founder Intellectual Property Rights Other Financial Benefit St. Jude Medical, NIH HeartFlow These are my conflicts of interest. The FAME 2 Trial was sponsored by St Jude Medical. FAME 2 was sponsored by St. Jude Medical 1

2 Fractional Flow Reserve
Proximal Pressure (Pa) Distal Pressure (Pd) FFR = Pd / Pa during maximal flow Pa Pd / Pa = 60 / 100 FFR = 0.60 Pd

3 FAME 2 Trial Stable patients with 1, 2, or 3 vessel CAD evaluated for PCI with DES n=1220 FFR in all target lesions Randomized Trial Registry At least 1 stenosis with FFR ≤ 0.80 (n=888) All FFR > 0.80 (n=322) Randomization 1:1 The FAME 2 trial included stable patients with single, double or triple vessel coronary disease being evaluated for PCI with DES. This study was different from previous trials evaluating PCI in patients with stable CAD in that FFR was first measured across all lesions. By doing this, patients with angiographically significant CAD, but not hemodynamically significant (and therefore unlikely to be responsible for symptoms or to cause a future event) were not included in the randomized study. On the other hand, patients who did have at least one lesion in a major epicardial vessel with an FFR ≤0.80 were included, ensuring a significant ischemic burden in those randomized to FFR-Guided PCI or to MT. The primary endpoint was D, MI, or urgent revasc at 2 years. PCI + MT MT MT 50% randomly assigned to follow-up Primary Endpoint: Death, MI, Urgent Revascularization at 2 years

This resulted in a significantly greater change in utility from baseline to one month in the FFR-Guided PCI arm of compared to essentially no improvement (0.003) in the MT arm.

7 FFR-Guided PCI Cost-Effectiveness
In-trial results $2,500 / QALY = $53,000 / QALY Three Year Projection $2,500 / QALY = $32,000 / QALY

8 Cost-Effectiveness CE Benchmarks: Hemodialysis ≈ $50,000 / QALY
WHO GDP std ≈ $150,000 / QALY >$150,000 / QALY $50K-150K / QALY <$50,000 / QALY Study Comparators CE Ratio COURAGE Angio-Guided PCI vs Medical Therapy ≥ $168,000 / QALY FAME 1 Angio-Guided PCI vs FFR-Guided PCI FFR-Guided PCI is Dominant (↓$ / ↑QALY) FAME 2 FFR-Guided PCI vs Medical Therapy $32,000 / QALY To provide some context for our findings, shown on this slide is the traditionally accepted cutoff of $50,000 per QALY based on hemodialysis. Some have argued that this number is outdated and that a more appropriate cutoff would be the one proposed by the WHO for the US of $150,000 per QALY. Using these thresholds, one can conclude that any strategy falling above $150,000 per QALY is not likely to be accepted as CE, any strategy between $150,000 and $50,000 per QALY is likely to be considered CE and a strategy falling below $50,000 per QALY can be considered CE. The COURAGE trial, which compared an angio-guided PCI strategy to MT, found that the CE ratio was at least $168K/QALY if not higher, and therefore not CE. In the FAME 1 trial, we compared an angio-guide PCI strategy to an FFR-guided one and found that the FFR-Guided strategy was “dominant”, meaning it cost less money and improved outcomes. Now in FAME 2 we have shown that the cost-effectiveness ratio of an FFR-guided PCI strategy compared to MT is favorable at $32,000/QALY

9 Conclusion: FFR-Guided PCI has higher initial cost than medical therapy. The cost gap narrows >50% by one year. Angina and quality of life are significantly improved by PCI. FFR-Guided PCI appears to be economically attractive in cost-effectiveness analysis
