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?
“From Gulf Oil to Snake Oil”: Congress Takes Aim at DTC Genetic Testing
It has been a busy week in Washington for direct-to-consumer (DTC) genetic testing companies. Following public FDA meetings and a new round of FDA device notification letters earlier in the week, representatives from three major DTC genetic testing companies (23andMe, Navigenics and Pathway Genomics) were hauled in front of Congress today to defend their companies, their industry and the practice of DTC genetic testing.
The hearing on “Direct-To-Consumer Genetic Testing and the Consequences to Public Health” was conducted by the House Committee on Energy and Commerce Subcommittee on Oversight and Investigations. The meeting was chaired by Representative Bart Stupak of Michigan. Materials from the hearing, including a briefing memorandum, opening statements from Stupak and Representative Henry Waxman of California and witness testimony are available on the Committee’s website. Also available are materials from the Government Accountability Office (GAO) investigation into DTC genetic tests. These materials include the report the GAO submitted to Congress – “Direct-to-Consumer Genetic Tests: Misleading Test Results Are Further Complicated by Deceptive Marketing and Other Questionable Practices” (pdf) – as well as a YouTube video featuring excerpts from undercover phone calls made by the GAO to DTC companies as part of their investigation (both of which are discussed in detail 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:
Personal Genomics Goes to Washington
Next week, the eyes of the personal genomics world will be focused on Washington, D.C., where the FDA and Congress will be meeting separately to consider the industry’s future. First, the FDA will convene a highly-anticipated public meeting (July 19th and 20th) to “discuss how the agency will oversee laboratory-developed tests (LDTs).” The FDA announced last month a proposal to develop a “risk-based” approach to oversight of all LDTs – a broad category that includes the vast majority of genetic tests, including high-complexity diagnostic tests (IVDMIAs) and direct-to-consumer (DTC) genetic tests. Hot on the heels of the FDA meeting, on July 22nd, the House of Representatives Committee on Energy and Commerce – which two months ago launched its own investigation into the personal genomics industry – will hold a subcommittee hearing on “Direct-to-Consumer Genetic Testing and the Consequences to the Public Health.”1
While the genomics and personalized medicine communities anxiously await the upcoming FDA and Congressional meetings, yesterday the future of personal genomics was being debated on the opposite coast, at a policy forum in San Francisco entitled “Genomics and the Consumer: The Present and Future of Personalized Medicine” (pdf). The forum, which was hosted by California State Senator Alex Padilla (sponsor of S.B. 482, the so-called “bioinformatics bill”) and personal genomics company 23andMe, was filled with speculation from personal genomics investors, providers, customers and commentators about what the FDA and Congress might have in store for the field.
Myriad Gene Patent Litigation Goes Down Under
On Tuesday, June 9, 2010, several plaintiffs, including a breast cancer patient and a cancer advocacy group, sued in a Sydney, Australia federal court to invalidate Myriad Genetics’ patents on the breast cancer susceptibility genes BRCA-1 and 2. According to published reports and comments by Australian patent law experts, the suit substantially tracks the much-publicized one filed in New York by the American Civil Liberties Union. In particular, this suit is also a frontal attack on the Myriad patents, seeking a judgment that genes in isolation from the body are products of nature and thus not patentable inventions.
The factual background in Australia seems a bit different. Myriad has granted an exclusive license to perform BRCA gene tests to a Melbourne company called Genetic Technologies Limited, which is a co-defendant in the case. But GTL has been reported to have “gifted” its patent rights to health care institutions, and not to charge royalties. Nonetheless, the plaintiffs’ lawyers have expressed concern about the possibility of GTL exploiting their monopoly as in the U.S., where the tests cost over $3,000. They note that on two earlier occasions GTL sent letters to hospitals telling them to stop testing. A number of Australian sources have also worried aloud about the implications of the patents for medical research.
Breaking: FDA Moves to Broadly Regulate LDTs
Earlier today, the U.S. Food and Drug Administration (FDA) announced that it will hold a public meeting July 19-20 to “discuss how the agency will oversee laboratory-developed tests (LDTs).” The FDA has made several high-profile announcements over the past month – particularly in the area of direct-to-consumer (DTC) genetic testing – but today’s development, despite its not receiving the same degree of media attention, is likely the most significant development to date.
Why? Until today, the FDA’s recent announcements have involved a series of letters to DTC genetic testing companies, beginning last month with Pathway Genomics and continuing last week with letters to five other prominent DTC companies. Despite all of the attention paid to these letters, the sum total of the FDA’s regulatory focus amounted to only a handful of products. Today’s announcement, on the other hand, declares the FDA’s intent to much more aggressively regulate the entire field of LDTs. While an exact count of the number of LDTs available is impossible, GeneTests.org lists more than 2,000 genetic tests from nearly 600 laboratories, numbers which do not even include genetic tests and other diagnostic products offered DTC. After having been criticized for a policy of case-by-case regulation, the FDA has answered with a move to regulate the entire field of laboratory-based testing.

What Five FDA Letters Mean for the Future of DTC Genetic Testing
The FDA has published online letters sent to five personal genomics companies – 23andMe, Navigenics, deCODE Genetics, Knome and Illumina – informing the companies that they are manufacturing and selling medical devices without appropriate FDA premarket review and approval. No surprise that the news that the FDA has sent out letters to some of the most well-known providers of DTC genetic testing products is already making waves. (Daniel MacArthur was the first to point me to the AP story, and Mary Carmichael of Newsweek and Andrew Pollack of The New York Times were among the first to dive into the substance of the letters.)
Below, we will discuss the immediate and long-term implications of the FDA’s most recent regulatory actions for the five companies receiving letters, as well as for the DTC genetic testing industry. First, however, a review of the letters themselves is required. Each of the five two-page letters is signed by Alberto Gutierrez, Director of the FDA’s Office of In Vitro Diagnostic Device Evaluation and Safety (OIVD), and follows a similar format throughout. To gauge the impact of these letters we will take them paragraph by paragraph.
More on Pathway and Walgreens: The Price of Visibility and Adding the FTC to the Regulatory Mix
Yesterday, direct-to-consumer (DTC) genetic test provider Pathway Genomics and drugstore giant Walgreens announced a partnership that will place Pathway’s tests on the shelves of thousands of Walgreens stores across the country. Earlier coverage from the GLR reviewed the announcement in detail, and examined whether the Pathway/Walgreens partnership might prove to be the catalyst for increased FDA regulation of DTC genetic tests.
Introducing the FDA to Pathway, but not to genetic testing. Continuing national media coverage has focused on comments from the FDA that the agency was unaware of Pathway’s genetic test and that it has opened an investigation into its legality. Yesterday, Office of In Vitro Diagnostic Device Evaluation and Safety (OIVD) Director Alberto Gutierrez told The Washington Post that he thought Pathway’s genetic test “would be an illegally marketed device” if the company proceeded with the announced Walgreens partnership. Gutierrez was also widely quoted as saying that the FDA was not aware of the test previously and that the agency was “in the process of investigating the test.”
Personal Genomics Follows Pathway to Corner Drugstore; Is Regulation Next?
The direct-to-consumer (DTC) genetic testing marketplace is on the move again. Just last week, in Mapping the Personal Genomics Landscape, I wrote that “predicting precisely which consumer services will be offered and how, if at all, they will be regulated, is impossible. All we know is that personal genomics consumers ten years from now are certain to have many, many more options than they do today.”
Turns out we only needed to wait a week – not a decade – for the landscape to shift again. Earlier today, DTC provider Pathway Genomics announced that it was partnering with drugstore giant Walgreens to offer its genetic testing service through most of that chain’s 7,500 stores.
Is Walgreens the Tipping Point for Personal Genomics Regulation? At first blush, this might appear to be nothing more than a creative product partnership between a fledgling personal genomics company and a giant drugstore chain. As it turns out, there are early indications that the Pathway/Walgreens partnership could turn out to be a tipping point in the regulation of personal genomics.
Genomic Privacy and Re-Identification Redux
New research published this week in the Proceedings of the National Academy of Sciences from Loukides et al. offers up a new method for preserving individual privacy while linking genomic and healthcare data. (“Anonymization of electronic medical records for validating genome-wide association studies.”) Daniel Cressey of Nature News and Katharine Gammon of Technology Review have concise (and free) summaries.
As we’ve written earlier (“Back to the Future: NIH to Revisit Genomic Data-Sharing Policy”), the ability to link – and to share – genotype and phenotype data (including medical records, particularly treatment and outcome data) will be essential to the development of the next generation of genomic research. One of the most common ways to link genotype and phenotype data is to combine genomic data with electronic medical records (EMRs). A particular patient’s EMR may contain everything from basic biographical information to family medical history to current diagnoses, including ICD codes. When it comes to associating genes with medical conditions, researchers rely on International Classification of Disease (ICD) codes to categorize individual patients by disease type and search for shared genetic variations that might play a causal role.
Cracking the Codes. Obviously identifying information (e.g., biographical information) is generally required to be removed pursuant to HIPAA regulations. ICD codes, however, are sometimes retained for purposes of genetic association research and, in some circumstances, a set of otherwise anonymous ICD codes pulled from an EMR can be traced backwards to identify the specific individual supplying the codes.
