Specialty CT manufacturer Xoran Technologies of Ann Arbor, MI, has received a warning letter from the U.S. Food and Drug Administration for documentation issues related to its MiniCAT scanner, a compact CT unit used for imaging of the sinuses, skull base, and temporal bones.
In a letter dated March 25, the FDA stated that MiniCAT is "adulterated" according to the meaning of the Federal Food, Drug, and Cosmetic Act due to a number of violations of Current Good Manufacturing Practices (CGMPs). The warning letter lists 10 specific violations, ranging from failure to maintain complete a device master record (DMR) for the product to failure to document that Xoran personnel are adequately trained according to federal requirements.
The FDA acknowledges that Xoran submitted a response letter to the FDA in December 2007 outlining its intention to comply with observations noted in a previous FDA inspection. However, the agency concluded that the company's response was "inadequate" because "there are no specific steps outlined to correct the violations and prevent their recurrence."
The warning letter advises Xoran to "fully evaluate" its record-keeping system to ensure that future "deviations" do not occur, specifically regarding design history files, device master records, device history records, and product monitoring records. The agency asks Xoran to submit a response within 15 working days of the receipt of the warning letter detailing the steps the company plans to take to address the deficiencies.
A representative of Xoran was not available to comment on the warning letter as of press time.
