So, a few points (I didn't downvote you).

1) First, FDA fast-tracks many bad things. Hundreds of millions of people were irradiated by scanners that FDA waved on through because a fellow .gov agency (TSA) sponsored them. So: even the risk-averse can't trust a single centralized regulator to be "risk-averse" rather than "pro-government". We need multiple regulators (see my posts elsewhere in the thread), where you can use things approved by the slower/expensive/safest one while I can use items approved by the faster/cheaper/riskier ones.

  Dr. Holdren passed the letter on to the Food and Drug 
  Administration for review. But, in the FDA's response, the 
  agency gave the issues little more than a data-driven brush 
  off. They cite five studies in response to the professors' 
  request for independent verification of the safety of these 
  X-rays; however, three are more than a decade old, and none 
  of them deal specifically with the low-energy X-rays the 
  professors are concerned about. The letter also doesn't 
  mention the FDA's own classification of X-rays as 
  carcinogens in 2005.
2) Second, the formal IND fast-track program you mention is very political to get into (on the device side there's something similar called Pathway to Innovation). Moreover, FDA doesn't count days like you and I count days. It's like an NFL game which is 60 minutes but actually takes three hours; every time they email you back, it stops their clock. And they can email you back to ask for data that takes months to gather. This is from a device consultant but the principle is the same for drugs:

  By law, FDA must respond to your 510(k) within 90 days, and 
  typically they do. The thing you have to understand is that 
  FDA measures 90 days about the same way the NFL measures 
  the 60 minutes in a football game. It's not unusual for the 
  clock to spend more time stopped than running.
3) Third, regarding thalidomide, as you probably know there were three major catastrophes that increased FDA power (1906 publication of the Jungle which birthed proto-FDA, 1938 elixir of sulfalinamide, and 1962 thalidomide) and another major catastrophe in the early 90s that reduced FDA power (FDA delays on AZT and slowdown of AIDS drugs).

Thalidomide in particular is to the FDA what 9/11 is to the TSA, it's the justification for everything they do. If you get into the history books you'll see that Frances Kelsey never actually suspected teratogenic effects; she suspected neurological issues. Moreover, thalidomide was actually a very efficacious drug for morning sickness, it was just unsafe. Yet the 1962 revision to the FD&C act added efficacy testing on top of safety testing.

That's weird. The thing is, toxicological/safety testing, even aggressive safety testing is "only" in the tens of millions, not billions. It's efficacy testing (and then comparative effectiveness) that really piles on the dollars. If the lesson of thalidomide was that we should do aggressive safety testing, then no one got the message, because Kefauver & Harris' 1962 amendments to FD&C meant we ended up spending several hundred billion dollars on efficacy instead.

Perhaps then the lesson from thalidomide might be that pregnant mothers should be much more risk-averse in what drugs they take. It's not really a lesson that says "we need to delay all drugs more", because due to pharmacogenomics some side effects are only going to be apparent when you introduce them into humans on a large scale anyway.

Moreover, risk can't be eliminated, and different people will have different risk profiles. What if a 70 year old man with terminal cancer wants to take an experimental, non-FDA approved drug? Do you sue like the FDA did in Cowan vs. US to prevent him from doing so?

For that matter, what if a 25 year old pregnant woman wants to take a new drug? Do we prevent her from doing so? Maybe we should, but we currently don't stop pregnant women from drinking alcohol or smoking cigarettes.

One has to think very carefully about whether every tragedy means one must ban or mandate something with a federal law.




While I don't disagree with most of your points here, I want to know more about your opinions on efficacy testing. It is definitely a strange corner of the FDA mandate and seems most justified by their marketing restriction power---the principle that marketing medical claims should be done from a position of earned, valid authority.

But it's definitely the most expensive and difficult to test component of FDA regulation. It's also awkwardly theoretical do to the sterility and white coatedness of the testing procedures (you and I both have something to say against RCTs). But at the same time, a market inundated with false claims to efficacy would be terrible. The current mobile health market is a fair comparison---many of them are efficacious, all of them would love to claim it, but nobody knows which ones.


So, regarding efficacy testing, I think the costs/benefits have to be assessed in full context. If you go back to the time before the FDA, it was a time of incredible wonder drugs and useless patent medicines. Kind of like the Internet: the price of being able to put up a domain name in 10 minutes with no centralized check for accuracy means information proliferates and the web/market/search sorts it out.

And we kind of know what a safe-but-not-necessarily-effective market for drugs will look like: the supplement industry. Supplements are cheap, they vary in effectiveness on a per person basis, and they have undoubtedly produced some really great things (creatine, omega 3). Take a look at this awesome graphic:

http://www.informationisbeautiful.net/play/snake-oil-supplem...

The thing is, with centralized regulation for efficacy two things happen. First, many of the bubbles on that graph never appear in the first place. Second, because they never appear, they never accumulate enough evidence/market size to rise up the list. We are choking the channel if centralized regulators require our minimum viable products to be not just safe, but highly efficacious.

The best way to see this is that centralized regulation kills iteration. Talk to anyone in the drug space: they'd love to be able to change their dosing methodology (altering dosage amount, frequency, formulation) or otherwise take advantage of serendipitous post-market findings. Viagra, famously, was initially intended to medicate blood pressure[1].

But right now they can't even change the labels on their drugs without the FDA's approval, which is why the average layman gets a folded-up chemistry textbook[2] rather than a user-friendly instruction manual, let alone a website which totes up other people's experiences with the drug. To get a sense of how much that could contribute to the patient user experience, see Help Remedies[3], which can get away with better UI/UX because they're dealing in generics.

Anyway, on net, I think something like a pharmacogenomic erowid.org [4,5] is the best way to establish efficacy. That would be distributed and the data would be public and constantly updated, with sample sizes far in excess of the current FDA process. Patients would get accounts and link their genomic information with the site after buying any new drug, and input their own survey data in order to see other people's (aggregated, anonymized) experiences. This would mean that you can launch safe drugs of unproven efficacy, and then collect efficacy data at a far larger scale than we do today. But this kind of innovation will only be possible in a jurisdiction outside the FDA's thumb.

To take the internet domain registration metaphor further, it also requires a centralized value authority (google) in order to be navigable. In some sense, Google's primary task is spam filtering---analogous to efficacy guarantees---which enable efficient information gathering.

I don't argue that the FDA is an efficient structure for doing efficacy testing, I just think punting the value discovery/marketing process to vague distributed processes isn't a good answer.

I think the supplement market is a great example as well. Many low value treatments saturate the market and the responsibility for making decisions is democratized and difficult. Canonical sources of efficacy information might not be needed as barriers to entry, but reputation, trust, and canonization are valuable heuristics in decision making processes and this leads to power.

If Google doesn't link you, you die.
