The Past, Present and Future of DTC Genetic Testing Regulation
[Editor’s Note: Newsweek science editor Mary Carmichael has a DNA Dilemma. As Carmichael debates whether to take a direct-to-consumer (DTC) genetic test, she is soliciting feedback from the DTC community, from the public and from other commentators, including myself. At the end of the week, she will make her decision.
On Tuesday, Carmichael and five commentators examined what can be learned from a DTC genetic test. Yesterday, the topic was whether DTC genetic tests are trustworthy, and whether the results can be cause for concern. Today’s topic is the regulation of DTC genetic tests. In addition to several short commentaries, including a much shorter version of the piece below, Carmichael has also posted a lengthy interview with two top FDA officials on the subject of DTC genetic testing regulation.
The column below is an expanded version of what appears over at Newsweek. To see all of the commentaries in Carmichael’s series, click here.]
The recent media attention focused on direct-to-consumer (DTC) genetic tests has left companies, investors, consumers and even regulators scrambling to figure out what comes next.
As the situation stands today, companies and their investors live in a climate of unprecedented regulatory uncertainty, causing delays in the introduction of new products and rendering an already inhospitable economic climate – for both fundraising and sales – even more challenging. Commentators and regulators caution consumers that some DTC genetic tests may be unreliable or, worse, harmful, but have yet to provide clear tools and guidelines for evaluating competing tests. And regulators, including the FDA, must balance their mandate to protect the health and safety of the public with that same public’s desire for autonomy, while also recognizing that innovation is a prerequisite for a healthcare system that must continue to improve outcomes while reducing costs.
Clearly, something must change. But what will that change be? And how will the field of DTC genetic testing evolve? Will DTC be able to continue its current business while regulators and companies engage in protracted negotiations? Will oversight weed out the “snake oil salesmen” and permit legitimate companies to flourish? Will it drive all genetic testing (temporarily) out of the hands of consumers?
Or will the field change in a dramatic and completely unexpected way?
While You Were Meeting: FDA Mails Letters to 14 More Genetic Test Providers
Earlier this week the FDA held a widely publicized two-day public meeting to discuss its planned regulation of laboratory developed tests (LDTs) (for more see: Day One Recap and Day Two Recap). Other than Monday morning, when the FDA presented background information on LDTs and some of the considerations that have pushed the Agency to pursue a “risk-based application of oversight to LDTs,” the top Agency officials at the meeting were conspicuously quiet. Elsewhere, however, the FDA was doing plenty of talking.
In letters dated July 19th, the first day of the FDA’s public LDT meeting, the Agency continued its crackdown on direct-to-consumer (DTC) genetic test providers, mailing letters to 14 providers of genetic tests. A list of all 14 companies and tests appears below.
The Conversation Continues: Recap from Day Two of FDA’s Regulatory Meeting
The second and final day of the FDA’s “Public Meeting on Oversight of Laboratory Developed Tests” (LDTs) brought forth many of the same comments and themes as the first. The primary difference was that, whereas the first day began with some comments from the Agency that provided a few hints about what the FDA has in store for LDTs, the second day was notable for the FDA’s near-total silence (although key officials were present and listening). Indeed, perhaps the loudest applause of the day was reserved for Sharon Terry of Genetic Alliance, who remarked that while she was glad the FDA had invited so many comments, “it would be nice [if the Agency] would say something back.”
Something Old, Something New. In addition to a reiteration of yesterday’s themes – especially the need for additional data demonstrating how LDTs are used and what harms, if any, they have inflicted on consumers and patients – a few new areas of discussion emerged over the course of the day. Those included:
