Updating the DTC Debate: Trial by Press Release, More FDA Letters, the Problem of Pleiotropy and New RUO Guidance
Later today I will join several colleagues here in Chicago, IL at the American Society of Clinical Oncology (ASCO) annual meeting for a panel discussion on Direct-to-Consumer Genetic Testing for Cancer: What Physicians Need to Know (pdf). (Daniel MacArthur and Misha Angrist will not be on the panel, although each joined us in authoring the pre-conference paper.)
This will, I believe, mark direct-to-consumer (DTC) genetic testing’s formal debut at ASCO. It should also serve as another reminder that, despite its relatively small numbers (both in terms of dollars and customers), DTC genetic testing continues to exert an outsized influence when it comes to conversations about the future of genomic medicine. This is particularly true when the discussion turns to appropriate policy and regulatory oversight.
In advance of ASCO, here are several items of interest from the past few weeks in DTC genetic testing.
New Diagnostic Guidelines and DTC Testing for Alzheimer’s Disease
Last month, the National Institute on Aging and the Alzheimer’s Association issued new diagnostic guidelines that divide Alzheimer’s disease into three distinct stages, reflecting recent evidence that the disease begins to affect the brain years before symptoms become evident. The expanded definition of Alzheimer’s includes two new phases of the disease:
(1) presymptomatic and (2) mildly symptomatic but pre-dementia, along with (3) dementia caused by Alzheimer’s. This reflects current thinking that Alzheimer’s begins creating distinct and measurable changes in the brains of affected people years, perhaps decades, before memory and thinking symptoms are noticeable.
At least for the moment, the new guidelines are intended to be used only with patients enrolled in clinical trials, making them more of a work in progress and not a standardized method of determining disease onset in Alzheimer’s patients.
Federal Alzheimer’s Activity. The revisions to the diagnostic guidelines – the first in nearly three decades – indicate how far scientists have come in understanding the disease and are reflected in new legislation introduced in both the Senate (S.738) and the House (H.R.1386) that would expand Medicare coverage of Alzheimer’s to cover “comprehensive Alzheimer’s disease diagnosis and services,” including for individuals who fall under stage (1) or (2) of the new guidelines.
Closer Scrutiny Ahead for DTC Genetic Testing Claims
The FDA’s public meeting on the future of clinical direct-to-consumer (DTC) genetic testing (which we have covered here, here and here) is continuing to draw significant attention from the media and other commentators. Most of the coverage, especially over the past 7-10 days, has added little that is new in the way of either reporting or analysis. One exception, however, comes from Robert VerBruggen of National Review in his column on “The FDA’s Genetic Paternalism.”
What’s new and interesting here is not the substance of VerBruggen’s analysis. Whether or not you agree with Verbruggen’s particular formulation, the “paternalism” critique of proposed FDA regulation of DTC genetic testing is not new. What caught our eye is a comment from deCODE genetics’ CEO Kári Stefánsson. When questioned by VerBruggen about his company’s marketing of its DTC genetic test offering, deCODEme (see screenshot) – which includes statements such as “your genes are a road-map to better health” – here is how Stefánsson responded:
“I think that is both cheesy and somewhat incorrect. I don’t know who came up with that, but whoever it is, is going to be duly punished,” [Stefánsson] said. “I think it’s safe to say we’ll probably be removing that statement and putting up something that at least sounds better.”
After its well-publicized 2009 bankruptcy, deCODE emerged in 2010 as a privately-held company and so it is unlikely the public will know whether Stefánsson follows through with his promise to “duly punish” the source of the “road-map” statement. On the other hand, whether and how deCODE follows through with Stefánsson’s not-quite-a-promise to change deCODEme’s marketing and claims is something that will happen in full view of the public.
2011 Personal Genomics Preview: It’s Déjà Vu…
Last January we kicked off the new year by posing “Five Questions for Personal Genomics in 2010.” Here were the five questions we asked:
1. Will the $1,000 genome live up to the hype?
2. Will personal genomics stay DTC?
3. How will the ongoing gene patent debate affect the progress of personalized medicine?
4. When and where will the next regulatory shoe fall?
5. Who will control the data?
A year later the question that comes first to mind is, has anything really changed?
The short answer is no, not fundamentally, although that is not meant to imply that nothing of note happened in 2010. Far from it, as significant legal, regulatory, policy and technological developments continued to reshape the personal genomics landscape.
With that in mind, we welcome 2011 with a look back at the year that was, and a look ahead at what to expect from 2011 and beyond.
Surreptitious Genetic Testing: WikiLeaks Highlights Gap in Genetic Privacy Law
The top news story the past two weeks: the release of hundreds of thousands of confidential American diplomatic cables by WikiLeaks. While dissecting diplomatic maneuvering is not a traditional area of expertise for the Genomics Law Report, a pair of cables did catch our eye.
The first is primarily a curiosity: the allegation that Chinese authorities are spying on deCode Genetics, Iceland’s most prominent genetic research company and provider of the direct-to-consumer genetic testing service, deCODEme. Nobody seems to know exactly what China is looking to gain by clandestinely exploring Iceland’s genetic genealogy. You are welcome to speculate in the comments.
The second raises broader issues: the revelation that the State Department’s ongoing human intelligence collection directives include requests for “biometric information” on key world leaders, including United Nations arms inspectors, the Director General of the World Health Organization (WHO) and key advisors and aides to United Nations Secretary General Ban Ki-moon. A separate cable detailing intelligence collection priorities in Africa’s Great Lakes region clarifies that “biometric information” includes “health [data]…fingerprints, facial images, DNA, and iris scans.”
Not disclosed in the WikiLeaked cables: why the State Department wants the biometric data or whether any have been successfully obtained.
Surreptitious Testing: An Overview. The cables are, however, a reminder that the law surrounding the surreptitious collection and testing of biometric data, including DNA, remains extremely murky.
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.
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.
FDA Puts the Brakes on Pathway-Walgreens Pairing; What’s Next for DTC?
Well that was quick. On Tuesday, Pathway Genomics and Walgreens announced a partnership to sell a saliva collection kit for Pathway Genomics’ direct-to-consumer (DTC) genetic tests in Walgreens’ thousands of drugstores nationwide. Less than forty-eight hours later, after the FDA repeatedly voiced its concerns about the arrangement, Walgreens has hit the brakes.
According to an MSNBC story, the FDA sent a letter to Pathway “asking the test maker to show it has regulatory approval, or prove why [the test] should be sold without the agency’s blessing.” In response, Walgreens is “elect[ing] not to move forward with offering the Pathway product to our customers until we have further clarity on this matter.”
Back to the Drawing Board. Despite its obvious significance, it is hard to be surprised by this latest development. When the Director of the FDA’s Office of In Vitro Diagnostic Device Evaluation and Safety (OIVD) tells The Washington Post that you would be selling an “illegally marketed device” if you proceed as intended, you should know the letter is already in the mail and retreat to the drawing board as quickly as possible.
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.
