Companies that buy other companies know perfectly well that they may acquire a few headaches in the process, but recent enforcement trends are making the acquiring companies more careful about acquisitions. Regulatory attorney Jennifer Bragg told an audience at this year’s meeting of the Medical Device Manufacturers Association (MDMA) that the smarter companies are doing their due diligence before approaching the target company, an exercise that could ultimately dissuade the would-be acquirer of the wisdom of the transaction.

While the U.S. FDA’s final rule for regulation of lab-developed tests (LDTs) has yet to emerge, there is some reason to expect the rule will be met with litigation from clinical lab associations. The FDA’s Jeff Shuren said in remarks to this year’s meeting of the Medical Device Manufacturers Association that there is a legitimate problem with the accuracy of many LDTs, adding that while stakeholders are at liberty to question the FDA’s rulemaking, the agency’s experience in this area indicates that the question of LDT reliability is not up for debate.

One of the problems with the European Union’s Artificial Intelligence Act is that it spans all sectors of the E.U. economy, an approach that Sen. Bill Cassidy (R-La.) suggested is less than optimal in remarks to this year’s meeting of the Medical Device Manufacturers Association.
