FDA Issues Warning to Scope Makers Over Spread of ‘Superbugs’

Companies skipped testing, manufacturing, and reporting requirements

Manufacturers of medical devices linked to recent “superbug” outbreaks at U.S. hospitals skirted a host of testing, manufacturing, and reporting requirements, the FDA said in warning letters to the companies released on August 17, according to a Reuters report.

The letters, sent on August 12, cite Olympus Corp., Pentax Medical, and Fujifilm Holdings Corp. with multiple violations found during inspections of their U.S. and foreign facilities.

Violations range from not properly evaluating cleaning, sterilization, and testing procedures to failure to report infections and other problems. Fujifilm and Pentax were also cited for violations in their marketing applications for the devices (duodenoscopes).

“The FDA takes these violations very seriously and will continue to monitor these firms to ensure they take appropriate corrective action,” the agency said in a statement. “However, currently available information indicates that the benefits of these devices continue to outweigh the risks in appropriately selected patients.”

The FDA first warned of the potential of duodenoscopes to transmit antibiotic-resistant bacteria in 2009. Since then, the devices have been implicated in “superbug” outbreaks at numerous U.S. hospitals, including one last year that may have exposed 179 patients at UCLA's Ronald Reagan Medical Center.

The FDA conducted inspections at all three companies' facilities earlier this year. In addition to testing and reporting violations, the agency found that Pentax and Fujifilm had failed to apply for proper approval of one or more devices.

Fujifilm claimed that its ED-530XT device was very similar to the ED-450XT5, which had been cleared by the FDA. Device makers are not required to file for separate clearance of a device if changes made are minor. But they must explain, in a document kept on file should the FDA ever want to see it, why they did not file for clearance.

In the case of Fujifilm's device, the FDA determined that there were significant differences between the ED-450XT5 and the ED-530XT and that a new 510(k) application was needed to demonstrate that the device was safe and effective and that it was substantially equivalent to a legally marketed device.

The FDA is also examining Pentax's justifications for not filing for 510(k) clearance of its ED-3670TK scope and changes made to its ED-3490TK device.
