According to the FDA’s Center for Devices and Radiological Health (CDRH), the changes were prompted by an increasing number of medical device advisory panel meetings in recent years. In 2008, there were 10 panel meetings covering 14 major topics. In 2009, there were 17 meetings on 20 topics, and 2010 is on track to surpass those numbers.
The FDA said that the increased activity has created challenges for CDRH and the way it operates panel meetings. In accord with current agency policy and guidance for advisory committees, the changes address staffing issues, voting procedures, and other items related to information presentation and flow of discussion.
In the past, panel discussions have not always reflected a panel’s final vote on approvability. Currently, instead of voting on the approvability of premarket approval applications, including conditions of approval, the panel will vote on the safety and effectiveness of a device and the device’s risk versus its benefit.
There are many issues involved in the FDA’s review of a medical device. Historically, the FDA’s presentations to panels included comments on approvability. With the changes, the FDA’s presentations will continue to include reviews of the agency’s data analysis, but will no longer include comments on approvability.
Before the changes, the agency medical device reviewers presented a unified, consensus analysis of supporting data. The reviewers will present together with data and analysis, the range of scientific opinion in the group. This move will allow more in-depth discussion on safety and effectiveness and risk versus benefit of the device under consideration. The FDA and CDRH will continue to evaluate panel procedures and make changes when necessary.
Jeffrey Shuren, CDRH director, said: “These changes are expected to empower the agency to make more effective decisions that are informed by more clear and focused discussion by panel experts.
“By making this change in voting procedure, panel members will address key scientific issues during their discussions, which will be reflected in their votes. The change also will allow panel members to address issues related to their area of expertise instead of regulatory issues that may be unfamiliar to them.”
