Protocol Overdue - FDA has not approved the study protocol, and it has been 6 months or more since issuance of the order.
Protocol Pending - FDA has not approved the study protocol, and it has been less than 6 months since issuance of the order.
Study Pending - This category is used from the time the protocol has been approved to the review of the first report.
Progress Adequate - The study has begun, and the study progress is consistent with the protocol (e.g., meeting enrollment schedule, follow-up rates, endpoints evaluated).
Progress Inadequate - The study has begun, but the study progress is inconsistent with the protocol (e.g., not meeting enrollment schedule, missing time point evaluations, poor follow-up rates, not all endpoints evaluated).
Completed - The sponsor has fulfilled the condition of approval, and FDA has closed the study. This is a final study status.
Terminated - The sponsor has not fulfilled or cannot fulfill the condition of approval (device is not currently being sold because the device technology is obsolete, study questions are no longer relevant, sponsor withdraws PMA, study cannot answer post-approval study question), all appropriate efforts to fulfill the condition of approval have been exhausted, FDA has terminated the study. This is a final study status.
Revised/Replaced - The sponsor has not fulfilled or cannot fulfill the condition of approval due to a failed study. All appropriate efforts to fulfill the condition of approval have been exhausted, and FDA has agreed to revise and or replace the original study design with a new design to fulfill the condition of approval requirement. The new design supersedes the failed study design.
Other - This is used when the study status does not fit another category (e.g., sponsor not marketing the device and has no plans to market the device; change in ownership underway; sponsor redesigning device and needs PMA approval prior to use in a PAS; pending separate study being used to address condition of approval). This is an interim study status.
See PAS guidance document entitled, "Procedures for Handling Post-Approval Studies Imposed by PMA Order."
Report on Time - FDA has received the scheduled Interim or Final Post-Approval Study Status Report by the due date set in the agreed-upon schedule.
Report Overdue - FDA has not received the Interim or Final Post-Approval Study Status Report by the due date set in the agreed-upon schedule.
Report Overdue/Received - FDA has received the Interim or Final Post-Approval Study Status Report, although receipt was after the due date set in the agreed-upon schedule.
Yes, there can be more than one PAS imposed by a PMA, PDP, or HDE application.
FDA launched the Medical Device Epidemiology Network (MDEpiNet) Initiative in 2010, to develop national/international infrastructure and innovative methodological approaches for conducting robust studies and surveillance, to improve the understanding of medical device safety and effectiveness throughout the device life cycle, through a Public-Private Partnership (PPP) with academia and other stakeholders (www.mdepinet.org). Aligned with these national, international, and MDEpiNet PPP efforts, FDA has been rethinking approaches for mandated studies imposed at the time of device approval.
Consistent with CDRH'S vision for a National Evaluation System, when appropriate, FDA has begun replacing traditional PAS requirements with surveillance based requirements where postmarket infrastructure is in place to support it. Under this model, the manufacturer agrees to support a national/international registry and ensures their device data is captured (e.g. registries, claims). These requirements are indicated in the PAS database as: "Comprehensive/Linked-Registry Based Surveillance".
Registry-based comprehensive surveillance leverages the national and international registry infrastructure that is linked with other data sources (e.g., claims data) for longitudinal assessment of device performance. This type of surveillance is relies on data collection within existing health care delivery systems. It generally involves shared responsibilities amongst multiple stakeholders, including professional societies running the registries, FDA epidemiologists performing the surveillance analysis, payers assisting with linking to administrative data, and industry supporting the registries).
Under Comprehensive/Linked-Registry Based Surveillance, manufacturers would actively participate as a stakeholder and support a registry to ensure that FDA surveillance can occur for the approved device over a specified period of time. Manufacturers may not need to submit any progress reports for the surveillance activity if FDA has access to the data and can conduct the analyses for the purpose of surveillance, as well as engage in quarterly discussions with the manufacturer and registry to discuss the findings.
The approval letters, as well as the Summary of Safety and Effectiveness Data (SSED), are posted on CDRH's PMA Approvals webpage.
Protocols and final study reports can be requested either directly from the applicant or from FDA under the Freedom of Information Act (5 U.S.C. 552) (FOIA). The FDA will comply with the requirements of 21 CFR Part 20 on the disclosure of information.
