FDA shuts down 23andMe

November 25, 2013

Wow!

The Food and Drug Administration has ordered DNA testing company 23andMe to stop marketing its over-the-counter genetic test, saying it’s being sold illegally to diagnose diseases, and with no proof it actually works.

I did not see this coming at all. Guess I was too focused on thinking about informed consent issues.

  1. I generally like regulation and wish the FDA would get on the case of mystics selling Chinese and Indian “traditional” cures — those can actually poison people. But instead they want to interfere with people’s right to know their genetic sequence — that’s not cool at all. Follow the money on this one — who is profiting?

    Seems like a reasonable thing to me. The letter states plainly that 23&me didn’t adequately respond to previous FDA issues.

    They’re dealing with a test that is unambiguously designed to diagnose. Oversight is warranted. They didn’t properly secure it. There’s no controversy here.

  4. Are they going to shut down genetic counseling? It’s exactly the same issue. Yes, I know the argument is “well, those are trained professionals”. But *they* can collect your saliva and send it off to a similar service and change thousands for it rather than a $100-$200? Bullshit.

    No, it isn’t “unambiguously designed to diagnose” anything. It just tells you what SNPs you have and if they are associated with anything. They make it quite clear that correlation isn’t causation. Anyway, they are a lot more interesting reasons to look at your SNPs than disease — looking at your ethnic makeup and where your ancestors is actually why I did it, for example.

    23andMe and other PGS are an important leap in personal consumer health information. I think the FDA recognizes this, but is under strong pressure to set precedence of how these services are regulated. 23andMe is going to be central to these regulatory decisions.

    As you mentioned DM, and the FDA outlined in their letter, the consequences of false positives or negatives could be huge. Without oversight, consumers are left in the dark as to the accuracy of the tests. This company might have the highest accuracy testing and the utmost ethical company standard, but without regulation, the door is open to the inevitable “me too” companies that possibly won’t. The FDA’s hand is forced on this one.

    My thought is that if you took your 23&me sequence to your PCP and demanded treatment, they’d do whatever test they’d normally do if you had the symptoms of whatever the SNP says you’d have a proclivity for. Should the FDA regulate this? Probably not, it’s not a basis for treatment. It’s like the FDA having to regulate every microscope in every lab (not just the ones used for diagnostics).

    They are a tech/entertainment company moving into medical diagnosis and research and in doing so, they’ve ignored the ethics and regulation of those fields. If Genentech markets a genetic test, they have a clear idea of the FDA rules they have to follow and know they are a highly regulated industry. A geneticist doing research at a university goes through all kinds of hoops in order to get their study approved.

    23 and me is the reality show equivalent of psychology research and crossed into the zone that the FDA regulates and didn’t take the FDA seriously. Glad to see that the FDA used its power to regulate. I think 23 and me will loose this one unless they get with the program and hire the same expensive lawyers companies like Genentech use.

    Because that is done by – yes – trained medical professionals, which have a state issued license and send it to a facility / lab that uses FDA-approved tests and equippment (which is why the stuff is more expensive). They can still sell their stuff for ancestral tracing but not to give you information about medical conditions.

    Will they have to mask SNPs that are correlated with disease? That’s kind of the issue here — its all about information access, not about anything requiring special medical-grade equipment or training. As a genomicist myself, I’d consider “medical professionals” as laymen regarding anything genomic anyway. Personally what I liked about 23andMe is that you could download the data yourself and run third-party analysis tools or brew your own if you are bioinformatically inclined.

    There was a good Radiolab sequence (#509) on the “written word and its consequences” where a family wrestles with a medical test (genomic screening for a disease) that has a very clear, but meaningful diagnosis – Chorea. I think it is important to receive test results like these in the presence of an expert who can provide counseling right there and then. Now, I am not sure if 23anMe did those tests but in general genomic information with a wide array of consequences should be ]handled responsible, approved tests that are verified are one part of it.

    I’m guessing where they really ran afoul is in the marketing — not simply providing the SNPs, but arguing that those SNPs would give useful information about health outcomes.

    They want to market themselves for health outcomes, and argued to the FDA that they would provide acceptable scientific evidence at some time in the future, that the studies were ongoing. They haven’t done so, by the scientific standards acceptable to the FDA.

    So, now, they can try to provide that evidence (a big undertaking), or change their marketing materials. I don’t think they’d be required to mask the disease SNPs, but, presumably, the buyer would have to go find their own information about the SNPs, rather than get a poorly evidenced list of correlations from the company.

    Pretty clear that 23andme is not acting in ignorance at this point but has been fighting/refusing the FDA.

    FDA has spent significant time evaluating the intended uses of the PGS to determine whether certain uses might be appropriately classified into class II, thus requiring only 510(k) clearance or de novo classification and not PMA approval, and we have proposed modifications to the device’s labeling that could mitigate risks and render certain intended uses appropriate for de novo classification. Further, we provided ample detailed feedback to 23andMe regarding the types of data it needs to submit for the intended uses of the PGS. As part of our interactions with you, including more than 14 face-to-face and teleconference meetings, hundreds of email exchanges, and dozens of written communications, we provided you with specific feedback on study protocols and clinical and analytical validation requirements, discussed potential classifications and regulatory pathways (including reasonable submission timelines), provided statistical advice, and discussed potential risk mitigation strategies. As discussed above, FDA is concerned about the public health consequences of inaccurate results from the PGS device; the main purpose of compliance with FDA’s regulatory requirements is to ensure that the tests work.

    However, even after these many interactions with 23andMe, we still do not have any assurance that the firm has analytically or clinically validated the PGS for its intended uses, which have expanded from the uses that the firm identified in its submissions.

    The biggest problem for SNP-based “testing” is that assigning ANY kind of causality is impossible. We don’t even understand what these (mostly) intronic and non-coding SNPs represent – are they simply markers or flagposts? Are they acting on cis or trans genes? Are they functional in any significant way? The basis for their association with diseases, especially complex polygenic disorders that we are primarily talking about here, is purely statistical in most cases. This was the promise and failure of GWAS studies.

    So it was always premature for these companies to be offering these tests and I am happy they have been shutdown. The science is just not there yet.

    Genetic counseling is a lot different. Often we are talking about non-synonymous mutations which are known to be causal and so testing is valid and the results are more interpretable.

    Has anyone here used 23andMe’s services? Do they tell you the data behind the various SNPs that they call out ask risk factors, etc? I currently work in patient/risk stratification and to say it’s not that easy to predict disease course or drug response is a *serious* understatement.

    My read of it (after 20 years in pharma, medical device, and 5 years associated with a personalized medicine company):

    Technology innovators came up with a cool information-based product and sold it at first as a novelty. FDA was fine with the “for entertainment purposes only” nature of the information provided. Entrepreneurs enhanced their product in the last year to provide data that was truly diagnostic or related to therapeutic guidance (BRCA1, CYP processing) and started pushing this information out. FDA was not pleased with the validation studies that had been done on that information and said it needed to hit 510k qualifications. Management had an experienced Reg Affairs Director (from xDx who faced similar challenges ?) but decided to play tough. Why play tough? My speculation would be that the validation testing would swamp the company or they thought they were too big/popular/cutting edge for the FDA to stop them. Having worked at a company with multiple warning letters from the FDA that ended with a consent decree stopping sales for 1.5 years, I would say popularity does not work. If the FDA perceives the risk to patient safety, it is up to the company to PROVE it is safe rather than for the FDA to show evidence of the harm done. I am curious to see how the next chapter reveals itself.

    Yes. They actually give you your SNP data as a downloadable text file. That’s what is awesome about it. And they give references to the studies linking SNPs to phenotypes so you can check *yourself* how solid the correlation is. SNP analysis is *science* not mere medicine.

    The top hit in my “health” section is for a trait that occurs in 11.4% of my subpopulation. It assesses my my risk at 1.98x this average. There is a lengthy description of the symptoms and treatment.

    It is immediately caveated that this assessment is based only on published associations with variants that are represented on their chip. For each SNP, the effect size is shown, with an explanation of what this means.

    It then gives a twin study heritability estimate for the disorder (66-80%) along with a list of environmental/lifestyle factors shown to affect risk (with links to articles).

    Next, there is a timeline for the condition that starts with it’s first recorded description (Hippocrates), includes the twin studies in the 1970s, and links to every association study for the variants on their chip.

    At the bottom of the page, it says that the test is not FDA approved and is not for diagnostic purposes.

    On the discussion for this trait, people discuss their symptoms and various remedies. There are 2 comments (out of 18) that present wingnut theories. There are a few naive questions (how can my risk be decreased if my dad had it?) which are accurately answered by others.

    Overall, I am underwhelmed by the potential risks presented by the type of information 23andMe presents and the way they present it. I believe those who say their advertising and marketing information might be misleading….I have never seen any of it. Seems like an easy fix.

    It does not seem to be recognized by most people in this thread that 23andme not only looks at SNPs associated with various health risks, but also tests a few dozen SNPs that are directly associated with inherited conditions/diseases. For instance I discovered that I had a rare condition with variable penetrance for developing Emphysema. I went to see my regular doctor to have it confirmed. Fortunately, it is not a problem now, but would likely become one as I get older if I did not know about it. With that information in hand, I have made appropriate lifestyle changes and can get treated, if necessary, before it is too late. All the other the other SNP-associated health risks generally range between two-fold higher and two-fold lower than the general population. Mildly interesting, but so what.

    I agree with JB. The FDA has their head up their ass on this. Quoting from the story above, the FDA said: “For instance, if the BRCA-related risk assessment for breast or ovarian cancer reports a false positive, it could lead a patient to undergo prophylactic surgery, chemoprevention, intensive screening, or other morbidity-inducing actions…” Yeah, that sounds plausible. A woman finds she has one of the bad BRCA genes and immediately runs out to have her breasts removed before confirming the condition. That would also require a doctor willing to do the surgery based only on the 23andme results.
