FDA Clearance for Impella ® 2.5 (K063723) 5 Supporting Clinical Data • Total of 129 patients • 100% from patients provided partial circulatory support ( < 6 hrs) during high risk PCI procedures (n=20 from FDA Safety Study 1 , n=109 from EU registry) • 510(k) Summary for K063723: “Abiomed provided a detailed analysis based on clinical data from a combination of 109 OUS and 20 US patients to address patient safety” 1. Dixon, et al., JACC, 2009 |
6 Since its 510(k) clearance in 2008, > 15,000 implants have been performed, ~12,000 in the U.S. Impella ® Device |
Impella ® Use in United States Since Clearance For use up to 6 hours, 90% of Impella use is for temporary ventricular support in the setting of HRPCI • Median duration of support during HRPCI is 60-80mins 1,2 • Majority of patients are surgical turn-downs 3 7 1. 60 mins median support duration, US Registry (Maini et al., CCI, 2012) 2. 78 mins median support duration, PROTECT II Study (O’Neill et al., Circulation, 2012) 3. 64% deemed inoperable by site surgical consultants in PROTECT II (O’Neill et al., Circulation, 2012) |

33 Summary Summary • Safety concerns mitigated with review of all available clinical evidence associated with the use of the Impella 2.5 • Substantial improvements in hemodynamics have been demonstrated with Impella 2.5 v. IABP • Examination of the totality of the clinical evidence associated with the use of the Impella 2.5 v. IABP support efficacy in defined patient populations |
34 Conclusion Conclusion • Comprehensive review of the totality of clinical evidence associated with the use of the Impella 2.5 device for its labeled “< 6 hour” indication supports the safety and efficacy of this device, particularly in patients undergoing high-risk PCI • Ongoing surveillance with a comprehensive National Registry is recommended to understand patient outcomes for these and other indications when applied beyond a randomized study |

• Abiomed Recommendation: Establish an inclusive Prospective National Registry of Percutaneous Circulatory Support • Leveraging current infrastructure of the Impella Registry • On-going registry, in cooperation with FDA and the appropriate professional society, would enhance the current risk mitigation controls for class II regulation of these devices • Combined with existing data, can potentially support future PMA indications 39 Recommendation to Expand US Impella ® Registry |
Impella ® Safety Record Supports Effectiveness of Current Controls • Since 2008, Impella has been used over 15,000 times worldwide and has had no recalls in the United States and 1 recall outside the US which effected a total of 4 units • There have been a total of 49 MDR’s since its introduction for an overall MDR rate of 0.32% • Only 16 of these MDR’s were associated with Adverse Events, for an MDR with AE rate of 0.11% 40 |
Conclusion 41 |
For temporary ventricular support up to 6 hours, including support provided during HRPCI, Impella meets the requirements for a class II designation 42 Conclusion Further, we recommend the establishment of a prospective national registry of percutaneous circulatory support as an added special control for class II regulation of current and future devices Sufficient information (valid scientific evidence) exists to identify risks and benefits The risks to health have been identified and quantified Special controls have been currently implemented to mitigate these risks Impella safety record supports effectiveness of current controls |
