Proposed Rule: Medical Device De Novo Classification Process

  • 1.  Proposed Rule: Medical Device De Novo Classification Process

    Posted 12-Feb-2019 15:59
    Is anyone aware of an industry group collecting comments on the proposed regulations for De Novo? The comment period closes on March 7th, and at this point there is only one substantial comment, and that only focused on FDA's right to conduct pre-approval inspections. I realize the comment period is frequently extended, but was just wondering if AdvaMed or any other group is aggregating comments.

    For those who have not reviewed the proposal, it's worth a look. Essentially the new regulations carry about 90% of the PMA submission requirements from 814.20 into the new De Novo requirements. With the exception of manufacturing information, De Novo requests will have the same content, same evidentiary standards, and same requirement to demonstrate clinical benefit as a PMA. Given the push underway to redefine the 510k program in such a way that an increasing number of submissions will be NSE, I find this a bit concerning. I agree we need more codification of the content and expectations for De Novo, but if the requirements are essentially identical to those for a PMA, one wonders at it's value. It seems less a de novo classification than a PMA approval with concurrent downclassification.

    I'd be interested in contributing to any ongoing effort to comment on this docket.

    Thanks,

    Sean

    ​I would be very surprised if additional comments are not posted.  I'm guessing they are taking what time is available to them to review the Proposed Rule thoroughly.

    I haven't looked at it yet, but I'm planning to review it and most likely comment.  I'm hoping for a "mini-PMA," with the basic requirements the same as a PMA, but the amount of data needed to meet the requirements scaled back.  I've been working forever on an analysis of the De novos that have been granted.  My information is no longer up to date, but the clinical data seemed to be scaled back from what you would expect to see in a PMA. 

    I think I'd rather see classification addressed early on, separately from safety and effectiveness.  I think it would be helpful if companies could resolve classification concurrently with collecting the data needed to support safety and effectiveness.

    I am unhappy that a newly classified De novo device would be immediately available to serve as a predicate.

    You can always submit comments on your own, but groups like Advamed are also probably commenting.  I view De Novo as Julie said a mini-PMA or a 510(k) on steroids, so it does not surprise me most of the requirements from 814 are in there now.  However, this is commensurate with the expected classification of the device, because remember there are still possibilities that a device going through De Novo could end up even as a Class I ... very slim possibility I know, but still possible.  There are other processes in FDA to deal with that such as 513(g) and Q-Submission, but personally I think the De Novo being moved the way it has fills a gap for those new and novel devices that were always automatically Class III.

    Julie, have to agree after working on a couple De Novo and also one from the other side ... let one company do all the hard work and then you can submit a 510(k) the day after.  I literally did that with one product.  I had someone in Europe ask me if there was any protection or orphan status that could be used as part of De Novo and told them no, you could submit a 510(k) against the predicate right away.  They were quite shocked and said hopefully the company has good patent protection !

    While I agree for subsequent 510k users, De Novo puts a structure and format in place for a novel device that didn't exist before, I wonder how much information is really available other than labelling  and a general summary to leverage, when the de novo predicate is another manufacturer's. Demonstrating SE in a 510k isn't exactly a cake walk these days.

    Hi Vidyalakshmi,

    Once the full decision summary is released, there is quite a bit of information about the testing that formed the basis for the decision - related specifically to the special controls FDA adopts for the device. It's quite a bit more comprehensive that a 510k summary. To Ginger's point, if novel studies are required this could cause a significant delay in order to construct a trial that demonstrates substantial equivalence.

    Yes, the clinical data requirement is seen by some legitimate smaller and mid-size companies companies as making a PMA more worth ​pursing than a 510(k) device, because they actually want to sell the device, rather than the company.  If these companies go 510(k), and the device looks like it will pick up any appreciable market share, I've been told that one of the behemoths can roll-out a cheaper version in as little as one year from date of clearance.  I don't think the behemoths will find a little bit of clinical data to be much of a bar for them, but maybe I'm overestimating them.

    The VC-driven startups prefer 510(k) devices as being better for getting rich quicker, and because they don't care what happens to the device after they get their ROI.

    So, again, it depends on your perspective.  My own is that I want to flush all of the clueless, resource-wasting, VC-driven medical device startups out of the medical device industry, if not off the face of the earth.  If there are any that are not clueless, they can stay.  I don't care who develops medical devices that offer real value to the market, I just want that to happen.

    My worst vision for the De novo is that it becomes a "De novo 510(k)," which I have taken to calling "starter dough."   A path for not very innovative devices that would have gone 510(k) in the good old days, when an artillery tank could have been cleared as SE to a bicycle, because they are both made of metal and rubber and are intended for use in transportation.  Put 'em through De novo, establish them as a new predicate, and then go right back to tweaking.

    My best vision is that the De novo becomes a path for truly novel devices that offer real value to patients, not just more "new and improved" devices that fall just a tad short of SE.  To the extent that the development of these devices represents greater business risk (not to be confused with clinical risk, which is what determines regulatory classification), then greater reward will be needed.  IMO.

    Hi Richard,

    I'd be fine with a "PMA-Lite", my concern is that I don't see that in the proposed regulations. Apologies in advance for the length of this post, but I think the implications of what FDA is proposing are getting buried in the language of the proposed rule.

    The only appreciable differences in the requirements as written in the proposed regulation are:
    • Clinical and nonclinical volumes are not required to be separate
    • A detailed summary is not required
    • Marketing history does not need to be supplied
    • Manufacturing information is not required (through pre-approval inspections - both BIMO and QSIT - are still on the table)
    • Environmental assessments are not required
    • Pediatric sub-populations are not required to be described
    • Color additives don't need to be FD&C or rationalized
    The criteria by which they will be evaluated are identical:

    860.289(d) FDA will use the criteria specified in § 860.7 to determine the safety and effectiveness of a device in deciding whether to grant or decline a De Novo request. FDA may use information other than that submitted by the requester in making such determination.

    814.45(c) FDA will use the criteria specified in 860.7 to determine the safety and effectiveness of a device in deciding whether to approve or deny approval of a PMA. FDA may use information other than that submitted by the applicant in making such determination.

    Of the differences outlined above, only the change that is substantive is the exclusion of the manufacturing volume. Issues with the manufacturing volume are rarely definitive in PMA approval processes.

    I think almost everyone is in agreement that the 510k system is broken, and needs to be addressed. What concerns me is that the regulation as proposed is essentially a PMA with a lower user fee and a 30-day shorter review. It's not PMA-Lite as it is written. 860.7 sets randomized controlled clinical trials as the de-facto standard by which De Novo applications will be judged. For certain devices, this is absolutely appropriate. The De Novo approach exists to acknowledge that there are devices that should not be subjected to the same standard. Maybe I'm missing it, but do not see a single place in the proposed regulation where this is acknowledged or addressed for the device that is under review. This is why I referred to it as PMA approval and immediate downclassification. A lower standard is set for follow-on devices, but the device that is the subject of the De Novo appears to be held to the same standards for approval as it would be if it were a PMA device. I'm not sure that this standard would be appropriate for, say, a little shocky-thing that makes mosquito bites itch less (ZapIt ) - no disparagement to the ZapIt device implied or intended.

    This is why I'm concerned about the lack of comment on the proposed rule. Either I'm losing my mind, or the proposed regulations are not PMA-Lite, as has been advertised. I will comment independently if I can't find a way to tag along with the 510k working group (we're one of those evil VC-funded companies, not full AdvaMed members), but having seen little substantive discussion of the rule in this forum, wanted to bring it to the attention of the RAPS community at large.

    Off soapbox now...

    Thanks,

    Sean

    No, it is not "PMA-Lite" as written.  But neither is it "PMA-heavy."

    I would love to do a YouTube video about the De novo (and really it would apply to PMAs too), set to the tune of ​Meghan Trainor's "All About That Bass," only with the lyrics "It's all about the risk."

    The keys here (not musical) are risk and valid scientific evidence.  There is a lot of flexibility in the latter, and it has always been FDA's judgment call, how much evidence is needed, even with PMAs, for "reasonable assurance that the device is safe and effective."  THAT is the standard, and I would expect/hope it to be the same for a De novo as for a PMA.  The "lite" and the "heavy" are in the EVIDENCE that is needed to reasonably assure FDA, not in the written "standard."  How much evidence FDA will need to be reasonably assured, I would expect to be determined by the level of clinical risk it thinks is associated with use of the device, which is, of course, reflected in its classification.

    Put in statistical terms, think p < .10 for De novo Class I, p < .01 for De novo Class II, p < .001 for PMA.  All are scientifically valid, but each one offers a different level of "assurance."  And each can be attained with different sample sizes.

    Yes Julie, I think (more or less) that is the way the process works now. But Sean's point, and it is a good one, is that no where in this regulations does it say that. Or even utter the words "risk based." Thus, 10 years from now, there would be nothing in the regulations to keep this from becoming a PMA but with a resulting Class II/510(k) route for changes, updates, and competitors. This could become a very real problem for all types of companies in the future if Class 1/2 devices start to be held to a Class 3 standard.

    g-

    ps - in defense of my "venture funded company" - our management team consists of all execs with over 20 years experience in what I suspect even Julie would consider "real companies" - so I doubt a good argument could be made that we don't know what we are doing or are trying to get away with anything.....Not all (probably not even most) "venture" companies are two guys who had an idea and have never done anything in the industry before....

    As far as risk-based, yes, that is the way the process works now, and, yes, that could change.  I don't see the other way the process works now, and has always worked...it's all really just a judgment call by FDA...changing without major legislation that would essentially revisit the regulatory framework established in the '76 amendments.

    PS  A far-from-clueless one, at the very least!  I should think the real companies would also be pretty fed up with the clueless, which have just been soaking up capital that the real companies could have put to much better use?

    My view is definitely skewed toward the clueless, typically of the academic variety, and therefore a lot of "two PhDs and a tech" types of startups, plus we have a large medical research community, so also "one MD and a tech."  Both frustrating and painful to watch sometimes.  Fairly recently, I've developed one consulting niche that basically aims to persuade them to give up before they hurt themselves.
     
    That said, you are in an industry stronghold, arguably THE industry stronghold, so your view is probably skewed the other way...

    Hi Julie

    I agree in part with that unhappiness of immediately available, but hopefully the fast followers would be somewhat dissuaded by any additional Special Controls (such as clinicals). De Novo manufacturer gets to help set then.

    Ginger and Richard, it depends on ​which of many perspectives you are looking at this from. 

    There is the perspective of the behemoths, which bring to the table the perspective of potential legitimate acquirer, potential rip-off artist, and internal developer. There is that of the legitimate small to mid-size device company and of the startup masquerading as a small to mid-size device company. There are the perspectives of inventors, VCs, owners of the privately held companies, corporate shareholders, speculative investors, insurers, providers, CROs, consultants, American employees, and, invariably last instead of first, of the hapless patient, not to be confused with patient advocacy groups, which have their own perspectives on everything.  Up in the bleachers, there is also the politicians.  And then, for me by far the most intriguing of the lot, there is CDRH's own perspective on all of this. I would kill to know.

    In this fractionated environment, what is good for the one is not necessarily good for the other, and not infrequently, quite the opposite.  I have my own perspective, but of equal or more interest to me is who wanted all of this in the first place?  Has it played out the way they thought it would?  Or is it another example of getting something imprudently wished for?  Or perhaps in the end, just much ado about nothing, after all this.

    If memory serves, some of this is related to the fact that De Novo is now part of the MDUFA commitments and has related FDA timing commitments around it....

    ​Yes, which is another way of saying "skewed heavily toward the interests of the behemoths," IMO.

    For me the missing piece here is how the behemoths now see the VC-driven startups.  I think Medtronic probably never saw them as much of anything other than an opportunity to increase its market valuation throughout most of the feeding frenzy of the 90s and 2000s.  By the late 2000s, I think it started to lose interest in little fish and decided it was "ready for some real food," eg, Covidien.

    As far as what happened with the 510(k), De novo, FDASIA...at the time, I think Medtronic may have been too busy "thinking strategic" to consider how their change in strategy (from little fish to real food) might affect their perspective on startups.  I don't think startups should have much interest to Medtronic now, not as food for market valuation.  This leaves the odd idea that startups might actually be of value for their innovative devices.  The problem here, as I see it, is that the market valuation feeding frenzy was a disaster for innovative devices, with many VC-driven startups destroying more than they developed ("9 out of 10...")

    Now I think (hope?) that we are at a point where there will be no room for clueless VC-driven startups.  I think there may be a place for the not-clueless, but that depends on their exit strategy.  If it involves acquisition, will the behemoths still want to acquire?

    Which brings me to my other missing piece.  In some quarters, it's very popular to say that the behemoths are "terrible at innovation."   I don't know that this is true, or at least that they are appreciably more terrible than many of the VC startups that parted fools from their money during the feeding frenzy.  I may have come up with a way to find out...will let you know.  In the meantime, I have been told that Medtronic is "very good" at me-too'ing.  Since this has been commonly accepted as "innovation" for decades, I don't see how that fits with "terrible."  Maybe not the kind of innovation I want to see, but still.

    I think the model Richard describes, "let one company do all the work" and perhaps more to the point, take all the risk, could work well for the behemoths...if they don't want to take on the risk and are ready to start acquiring innovative devices instead of market valuations.

    But what do I know. All I've got to go on are a few little clues I find here in my little tidepool, and a few more I manage to scavenge now and then, on my expeditions inside the bubble.

    This still leaves me wondering who started this, as opposed to who got on board later on.  Anything that results in legislation tends to have a long, if not always very visible, history.

    It's the docket itself on Regulations.gov that has only 3 comments. One is a compliment to a pharmacist in Missouri, one is a complaint about remote monitoring and how it impacts patient billing, and the final one is actually a substantive comment related to pre-approval inspection authority.
