“The FDA should develop a comprehensive medical device postmarket surveillance strategy to collect, analyze and act on medical device postmarket performance information” The FDA 510(k) Clearance at 35 Years IOM July, 2011
JAMA, Nov. 2011; 306
National Coverage Determination TAVR is covered for treatment of symptomatic AS when furnished according to an FDA approved indication System has received FDA PMA for an approved indication 2 cardiac surgeons have independently examined and evaluated suitability Heart team
National Coverage Determination “TAVR is covered for uses that are not expressly listed as an FDA approved indication when performed within a clinical study that fulfills all the following.”
Post Market Surveillance Device performance in the wider community What Happens Next? Post Approval Studies Post Market Surveillance Designed to assure continued safety and efficacy addressing specific questions Device performance in the wider community
Post Approval Studies Vary in design and scope Assessment of device performance and risk benefit ratio through PLC Study specific endpoints of concern – stroke Identify unexpected serious risks – e.g. device failure May focus on population used for approval or expand to other populations Track real world introduction including selection creep, device iteration
Post-market Surveillance: Goals The numerator and denominator of patients receiving a device are both crucial Primary goals are the assessment of effectiveness and safety when applied in clinical practice for ALL patients who receive the device, not a subset Use existing infrastructure of national clinical data repositories to capture ALL patients undergoing device placement: ACC/NCDR and STS
IDE Traditionally corporate sponsor Selected sites Data resides with corporate sponsor Issues of full access/full reporting Adverse events reporting
Alternative Access Background FDA approved in November 2011 Inoperable patients Femoral access Problem Many patients not suitable for TF procedures
Alternative Access IDE and protocol approved Jan. 17, 2013 Research study using TVT Registry as data collection platform Approaches Transapical Transaortic Trans-subclavian/axillary Trans-iliac
Alternative Access Prospective study 1000 patients until Dec. 31, 2018 CMS reimbursement anticipated for eligible patients enrolled in this research study Local consent form approved by local IRB sufficient provided that there is documentation of discussion about AA

Establishing the Registry February 2011 Discussions between FDA, ACC and STS July 2011 TVT Registry proposed at the FDA Advisory Panel for Edwards Sapien Valve November 2011 Edwards Sapien THV approved in U.S. Dec 2011 STS/ACC TVT Registry launched May 2012 CMS issued a NCD for transcatheter valves mandating participation in a national registry as a requisite for reimbursement July 2012 TVT Registry v1.1 launched
Current Status 150 sites enrolled 1500 patient records Nested registry for PAS 2 for Edwards Sapien Valve
Regulatory Issues Industry Training, credentialing, ? policing One hurdle after another Long delays, pre IDE studies, PAS, PMS Changing regulatory climate Changing endpoint analyses Lengthy expensive – PAS, PMS, IDE Non-approved indications Support new and old technology Adverse event reporting
Is regulatory process too lax? Conclusion: Premarket approval of cardio- vascular devices by the FDA is often based on studies that lack adequate strength and may be prone to bias
UDI system incorporated into EHR National and international device registries Modernize adverse event reporting New methods for evidence generation, synthesis and appraisal
Post-market Surveillance: What is Involved Infrastructure, well-designed data forms to allow seamless collection of data for: New iterations of the device(s) New adjunctive strategies (embolic protection, etc.) Changes in approach (transapical, subclavian, transfemoral) Changes in patient selection criteria and outcome over time
National Coverage Determination TAVR is covered for treatment of symptomatic AS when furnished according to an FDA approved indication System has received FDA PMA for an approved indication 2 cardiac surgeons have independently examined and evaluated suitability Heart team
Clinical Research Study Outcome measures defined Principal purpose is to test whether a particular intervention improves outcome Does not duplicate existing studies Scientific integrity http://www.icmje.org Registered on clinical trials.gov Protocol approval by CMS Public reporting of data, monitoring prespecified
IDE Facilitate reimbursement by CMS Foster study in broader patient groups, e.g. PTCA Empower unbiased scientific study and reporting Result in expanded approved indications
IDE Elements Written protocol: methodology Investigator certification Local IRB approval Informed consent All data forms Device manufacturing details Prior investigations Written monitoring procedures Detailed Description Monitoring and reporting SAE Annual progress reports
IDE Issues Site selection, IRB involvement Protocol development Informed consent Monitoring Adverse event reporting Funding Who will do the work and hold the IDE

Post Approval Studies History Typically FDA mandated, industry supported Little harmonization of definitions or data specifications Specific patient populations – numerator known but no denominator Do not track device iterations Conflict of interest Typically no blend of clinical and administrative data
Societal Registries What could they offer? Harmonized objective audited data Sophisticated analytics without COI Blend clinical and administrative data Capture all procedures – numerator + denominator Capture medically treated patients Track device iterations and changes in patient selection Serve as FDA, CMS mandated studies
STS/ACC TVT Registry New outcomes registry of TAVR, approved in the U.S. November 2011 >400 data elements Web based data entry Standardized data elements – VARC definitions 30 day risk adjusted clinical outcomes Linked to CMS claims data for long term outcomes Will be harmonized with STS database for surgical AVR

TVT Registry Challenges Start up and ongoing costs Compliance/participation Burden of data collection/entry Completeness of data collection Auditing/data accuracy Linking of TVT registry with CMS data Research questions
Outcome Report Metrics In hospital Mortality & adverse events Procedure success Acute kidney injury 30-day and 1-year outcomes All cause mortality Stroke MI Bleeding events Valve performance Quality of life (KCCQ)
Data Quality Site training and support Data integrity checks Data audits Adjudication of selected events Stroke TIA Aortic valve re-intervention
Innovative Aspects of TVT Registry Capture of all devices (mandated for reimbursement) Will incorporate UDIs Immediate focus on critical issues Short-term risk adjusted clinical outcomes Long-term outcomes by linkage with CMS claims data Quality of life outcome data Risk prediction algorithm will be developed Appropriateness of use assessment Expansion of FDA “label” indications Nested PAS studies
TVT Registry Funding Initial start-up expense borne by the professional societies Ongoing expense funded by site initiation and annual participation fees Funding received from Edwards Lifesciences for PAS study
Development of the TVT Registry “The Good” New collaboration between many partners Capability for robust post market surveillance Expansion of the role of registries
Development of the TVT Registry “The Bad” Burdensome data collection for sites Initial and annual expense for sites Site agreements, contracts, informed consent Communication between all stakeholders is a constant challenge in “uncharted waters”
Development of the TVT Registry “The Yet to be Determined” Different stakeholders have different goals FDA “Safe and effective” CMS “Reasonable and necessary” Professional Societies “Appropriate use”, guidelines
TVT Registry Next Steps Annual reports at society annual meetings Linkage with CMS database for long-term outcomes Develop TAVR risk model Global harmonization of this registry with OUS databases/studies based on VARC common definitions Extension to pre-market use Link with STS Adult Cardiac database for comparative effectiveness with surgical AVR
