The U.S. FDA’s draft rule for regulation of lab-developed tests (LDTs) was a long time in coming, much longer than any legislative proposals to overhaul the agency’s regulatory mechanisms for these tests. Nonetheless, Scott Whitaker, president and CEO of the Advanced Medical Technology Association (Advamed), believes that the FDA draft rule is likely to prompt Congress to pass the Verifying Accurate, Leading-edge IVCT development (VALID) Act, a development that would truncate an FDA final rule that would almost certainly face litigation.

The U.S. FDA’s draft rule for regulation of lab-developed tests (LDTs) carries an exceptionally ambitious timeline of completion and enactment by the time the next user fee agreement kicks in, and some see big problems with the timeline laid out by the agency. However, the FDA’s Elizabeth Hillebrenner said that Congress can tweak user fee legislation such that a specific set of user fee sources kicks in off schedule, thus giving the agency a little more leeway in completing any activity related to the proposed rule.
