DTC Genetic Testing and the FDA: is there an end in sight to the regulatory uncertainty?
Editor’s Note: This was first published at Genomes Unzipped and was co-authored by Daniel MacArthur and Luke Jostins. Genomes Unzipped received 12 free kits from Lumigenix for review purposes, and Dan Vorhaus has provided legal advice to the company. Genomes Unzipped plans to release a full review of the Lumigenix service in early July.
Last month three direct-to-consumer (DTC) genetic testing companies opened their mailboxes to find a slightly ominous but entirely expected letter from the FDA. The three recipients (Lumigenix, American International Biotechnology Services and Precision Quality DNA) received substantively equivalent letters, with the FDA warning each company that its genetic testing service “appears to meet the definition of a device as that term is defined in section 201(h) of the Federal Food Drug and Cosmetic Act,” and that the agency would like to meet with company representatives “to discuss whether the service [they] are promoting requires review by FDA and what information [they] would need to submit in order for [their] product to be legally marketed.”
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.
Weekly Roundup: FDA Regulations, Science Funding and Newborn Screening
With so many developments at the intersection of genomics and the law, there is often a variety of interesting stories that, for one reason or another, don’t find their way into a full-length posting on the Genomics Law Report. In this post we recap several recent key developments and, at bottom, round up all of the recent tweets from @genomicslawyer.
Continuing Uncertainty Over FDA’s 510(k) Overhaul. As we have discussed previously, in addition to overhauling the approval process for direct-to-consumer (DTC) and laboratory developed tests (LDTs), the FDA is also in the midst of a comprehensive review of its 510(k) clearance process for medical devices.
Weekly Roundup: Science Funding, DTC and Medical Device Caucusing
With so many developments at the intersection of genomics and the law, there are often a variety of interesting stories that, for one reason or another, don’t find their way into a full-length posting on the Genomics Law Report. Here we recap several recent key developments and, at bottom, round up all of the recent tweets from @genomicslawyer.
The Continuing Threat of Decreased Science Funding. At least for the moment, the two houses of Congress appear, finally, to be edging toward a budget compromise that would bridge the $51 billion gap between the House bill (which passed at the beginning of March) and the most recent Senate proposal. That’s a good thing, given that the current continuing resolution is set to expire on April 8.
Nevertheless, it seems increasingly clear that federal science funding is unlikely to increase from its fiscal year 2010 levels, and funding almost certainly will not meet the targets President Obama set in his FY 2012 budget proposal.
The FDA and DTC: Time to Set the Record Straight
Earlier this month an FDA advisory panel met for two days to consider a range of issues pertaining to clinical direct-to-consumer (DTC) genetic testing. The non-voting advisory panel’s discussion (pdf), including whether certain genetic tests or categories of tests should be made available only through qualified healthcare professionals, sparked considerable controversy (see here for a collection of links) and confusion.
In response, the FDA agreed to reopen the public docket in order to receive additional public input on scientific issues concerning DTC genetic tests. The docket will reopen tomorrow and will remain open through May 2nd (pdf).
For those with an interest in the FDA’s oversight of DTC genetic testing, this is the first of several opportunities to be heard. In addition to the newly reopened public docket, the FDA has also announced its next “town hall discussion” with top officials from the Center for Devices and Radiological Health (CDRH), the FDA center responsible for the regulation of medical devices, including genetic tests. Both CDRH director Jeffrey Shuren and OIVD Director Alberto Gutierrez are scheduled to participate in a public question-and-answer session on May 5th in Orlando, FL. An additional town hall discussion is slated for San Francisco, CA later in the year. The Genomics Law Report will post additional details for that meeting as they are made available.
Twitter Roundup: FDA DTC Edition (and a new format)
Beginning this week, we are unveiling a new format for the Genomics Law Report’s regular Twitter Roundup. In addition to cataloging Dan’s @genomicslawyer tweets, we will also be offering short summaries of several key developments pulled from those tweets which, for one reason or another, did not find their way into a full-length post. Think of this as a combination between the always informative Friday Links posts at Genomes Unzipped and The Cross-Border Biotech Blog’s semi-regular feature “This Week in the Twitterverse,” which was the original inspiration for the GLR’s Twitter Roundup.
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.
Considering the Impact of Yet Another Proposal for Genetic Legislation
Last month we examined Massachusetts’ proposed Genetic Bill of Rights. Last week, we looked at a similar proposal to expand individuals’ property and privacy rights in genetic information proposed in the Vermont legislature. Today, we head west to California to examine another piece of recently introduced genetic legislation.
A New Padilla Proposal. The California proposal comes from state Senator Alex Padilla. If Padilla’s name sounds familiar, it is likely because he is the same Senator Padilla who introduced a widely discussed “bioinformatics bill” to the California legislature two years ago. That bill (S.B. 482) was drafted with the close participation of direct-to-consumer (DTC) genetic testing company 23andMe, and 23andMe and Senator Padilla later co-sponsored a policy forum in San Francisco on “genomics and the consumer” (at which I presented).
Unlike Padilla’s earlier effort, which would have significantly altered the regulatory environment for so-called “post-CLIA bioinformatics services” (basically, genetic interpretation performed after the generation of genetic genotype or sequence data in a CLIA environment), 2011’s effort (S.B. 559 (pdf)) will almost certainly be viewed as a much less controversial proposal.
The FDA and DTC Genetic Testing: Setting the Record Straight
Earlier this week, I attended a public two-day meeting of the FDA’s Molecular and Clinical Genetics Panel (“MCGP”) in Gaithersburg, MD. The meeting was not particularly well attended (approximately 100 people were in the room) but the topic of the panel’s deliberations – how to appropriately regulate direct-to-consumer (DTC) genetic tests – has sparked intense and ongoing public debate.
Numerous private and public conversations following the meeting indicate that there is considerable confusion about what actually happened at the meeting, including what the MCGP “recommended” to the FDA and what the FDA is likely to do with those recommendations. With that in mind, I followed up today with Dr. Alberto Gutierrez and Dr. Elizabeth Mansfield of the FDA’s Office of In Vitro Diagnostic Evaluation and Safety (OIVD) to seek clarification.
