510(k)s Are on the Hot Seat!

FDA is in the cross-hairs again. Expect new legislation from Congress in the upcoming administration, and perhaps a complete overhaul of the device review process but until this is sorted out, expect more delays while FDA tries to fight off allegations, clean up internally and make case-by-case decisions as to which devices are “high risk” and require more clinical data.

A recent article in the NYTimes cited that nine FDA scientists expressed complaints about the device review process last May to the then commissioner, Andrew von Eschenbach. Displeased with the progress and results within the Agency, they then wrote a letter to Congress in October, pleading for an investigation. In November, the House Committee on Energy and Commerce announced it would begin an investigation. A similar letter was written to the President Obama’s transition team.

The scientists criticize the lack of extensive testing for some devices and allege that an FDA official overruled agency scientists and approved the iCAD SecondLook Digital Computer-Aided Detection System for Mammography, used with screening equipment made by Fujifilm Medical Systems after receiving a phone call from Connecticut congressman, Christopher Shay (R). Mr. Shay lost in re-election in November.

The focus of this and another recent NYTimes article criticize what they refer to as the “abbreviated” process or with minimal oversight, actually the 510(k) process for devices that were classified as Class III but for which a PMA would be required if called for by FDA. The FDA scientists say some of the devices are “so complex or novel that extensive clinical trials should be required”.

The Food, Drug and Cosmetic Act was amended in 1976 to add the Medical Device Amendments. FDA classified all devices in existence at the time to one of three Classes depending on risk. Class I devices are lower risk and are mostly exempt from premarket review but are subject to other controls. Class II devices must demonstrate substantial equivalence with devices that were on the marketed prior to 1976, via a 510(k) (named after the section number of the FDCAct that describes them). In order to be cleared, there must be no new questions of safety or effectiveness as compared to the predicate Class II device. Class III devices that were on the market before this date could be reviewed via 510(k) until FDA called for a Premarket Approval Application (PMA), At the time the PMA is called, there is an opportunity to petition for downclassification to Class II. PMAs, for the most part, require clinical data to support safety and effectiveness, as well as other detailed information to support approval. In 1990, Congress enacted additional laws that directed the Agency to set deadlines for when all Class III devices would be required to have PMAs. Despite plans, most of these devices are still allowed via 510(k). All new devices, for which there is no predicate, and combination products that have the device as the primary mode of action require a PMA.

A good strategy is to have early communication with FDA about your planned projects. Prepare clear preclinical and, if necessary, clinical plans to present to the Agency. There are no guarantees that FDA won’t require additional data but early and continuous communication can help keep things on track. Identification of FDA concerns up front can help companies make better business decisions regarding projects given the expected regulatory hurdles.
