FDA Nanotechnology Report Outlines Scientific, Regulatory Challenges

The Task Force reports that nanoscale materials potentially could be used in most product types regulated by FDA and that those materials present challenges similar to those posed by products using other emerging technologies. The challenges, however, may be complicated by the fact that properties relevant to product safety and effectiveness may change as size varies within the nanoscale.

The report also says that the emerging and uncertain nature of nanotechnology and the potentially rapid development of applications for FDA-regulated products highlight the need for ensuring transparent, consistent, and predictable regulatory pathways.

Anticipating the potential for rapid development in the field, the report recommends consideration of agency guidance that would clarify, for example, what information to give FDA about products, and also when the use of nanoscale materials may change the regulatory status of particular products. As with other FDA guidance, draft guidance documents would be made available for public comment prior to being finalized.
