In Praise of Extreme Medicine

This Buzzfeed article on unauthorized poop transplants has much of interest:

A spate of studies over the last decade have convinced microbiologists and doctors that “fecal microbiota transplantation,” or FMT, works for at least one disease: a deadly bacterial infection in the gut known as Clostridium difficile, or C. diff. No one knows whether the procedures work on other conditions, though dozens of clinical trials are testing them on people with irritable bowel syndromeCrohn’s diseaseobesitydiabetesepilepsyautism, and even HIV.

The science is advancing rapidly, with more and more scientists excited about the potential and potency of fecal matter and the microbes in it. The FDA regulations on these procedures, however, keep them out of reach for most patients: Since 2013, the agency has banned doctors from doing fecal transplants on anything except C. diff.

A rogue clinic in Tampa, however, provides the carefully sourced material and explains to patients how the procedure is done. Since the procedure is simple, lots of experimentation is going on which upsets some people.

Poop from an unscreened stranger could carry serious infections, like hepatitis or gonorrhea, or dormant viruses.

No doubt–this is why we also ban sex and french kissing.

I suspect that many of the so-called treatments are crazy but people do a lot of crazy things. It’s odd that we allow some crazy things and ban others—even more that the crazy things we allow are sometimes socially useless while the crazy things that we ban are sometimes socially valuable.

The case for banning extreme sports, for example, is much stronger than the case for banning extreme medicine. Extreme sports don’t provide much benefit to the rest of humanity, other than some entertainment of questionable social value. Extreme medicine, on the other hand, has the potential to improve all our lives and at the very least is a useful warning about what not to do. Yet, extreme sports are lauded, or at least treated as mostly your own business (we do put some regulations on boxing and race car driving), while extreme medicine is heavily regulated and socially frowned upon.

My attitude is the reverse. You want to risk your life climbing without ropes? Knock yourself out–but don’t expect any support from me. I won’t even watch Alex Honnold because I think that what he does is Russian roulette and I do not approve. But, you want to risk your life trying an unapproved medical treatment? Sir, I salute you. Give that man a Nobel prize.

Pharmaceutical Reciprocity for Canada

If pharmaceutical reciprocity is a good idea for the United States, it’s a great idea for smaller countries. Indeed, this is mostly what happens in practice, even if not by law, since smaller countries can’t afford or justify the expensive US process. Fred Roeder of the Montreal Economic Institute makes the case for reciprocity in Canada:

…reciprocal recognition of drug approval authorities on both sides of the Atlantic would incentivize Canadian, European and American authorities to spend less time and money conducting parallel reviews. If the HPFB, the FDA or the EMA approved a drug, patients in Canada, Europe and America would have immediate access to it — increasing consumers’ choice as new drugs are offered to patients faster and more affordably, with less red tape driving up costs.

A reduction in approval time can be a win-win for patients and firms because a decrease in approval time is an increase in effective patent length without an actual increase in patent length. The numbers below are optimistic, but the idea that streamlining approval can increase profits and stimulate investment is correct:

These market-oriented reforms would not benefit not only consumers, but the pharmaceutical companies as well, expanding the timespan of the patents. On average, new drugs have a mere 10 to 14 years of patent protection remaining by the time they are sold to consumers after they have successfully jumped over all the government hurdles. Streamlining the drug approval process would increase the timespan of patented drugs on the market by 50 to 70 per cent.

Roeder also mentions Bart Madden’s important book Free to Choose Medicine. (For those who don’t know, I am proud to be the Bartley J. Madden chair in economics at Mercatus at GMU.)

Apple Watch can detect an early sign of heart disease

MacWorld: Developers of the Apple Watch app Cardiogram worked with researchers leading the University of California San Francisco’s Health eHeart study to develop a ResearchKit-based study of their own called mRhythm. On Thursday, Cardiogram and UCSF’s cardiology division are presenting the results of that 14-month study, which collected more than 100 million heart rate data points from more than 6,000 Apple Watch users. Cardiogram developed a machine learning-powered algorithm that can detect atrial fibrillation, which is often asymptomatic.

Cardiogram’s algorithm was tested against an in-hospital test called cardioversion. Patients experiencing atrial fibrillation, which affects one in four people in their lifetime and causes 25 percent of all strokes, wore an Apple Watch while undergoing cardioversion to compare outcomes. Both segments, the cardioversion test and the Apple Watch’s heart rate data, were blinded against whether the patients’ heart rates were normal or abnormal, then sent to Cardiogram’s algorithm. The results: the Apple Watch data detected atrial fibrillation 97 percent of the time.

Apple has been communicating privately with the FDA for years about medical devices and so far the FDA has taken a light touch to Apple but these issues are coming to a head. As with the regulation of DNA tests, the regulation of these devices is going to raise important free speech issues. It’s one thing to ensure that the devices do what they say they do at reasonable accuracy (measure heart rate, identify genes etc.) but regulating what advice may be given on the basis of such readings is problematic. Can the FDA regulate a website that says go see your doctor if your heart rate monitor exhibits these particular readings? Why is an app that tells you the same thing any different?

China Creates SEZ for Medical Tourism

The Chinese government have set up a special economic zone for medical tourism.

Hainan Boao Lecheng international medical tourism pilot zone, the first of its kind in the country, was approved by the State Council in 2013. It enjoys nine preferential polices, including special permission for medical talent, technology, devices and drugs, and an allowance for entrance of foreign capital and international communications.

The pilot zone also has permission to carry out leading-edge medical technology research, such as stem cell clinical research.

The zone, for example, offers a way to skirt the slow Chinese FDA (and presumably the slow US FDA as well).

Established in 2013, the Hainan program will open up new treatments–including Keytruda–to affluent Chinese residents who can afford the travel and medical costs, while other patients will have to wait for regulators to approve them. In recent years, mainland Chinese patients have increasingly traveled to Hong Kong or elsewhere in the face of lagging drug approvals by the China FDA and high treatment costs.

The zone is too small to have a significant impact on worldwide R&D but China’s original SEZs soon expanded. The SEZ could also encourage some interesting experiments. Keep an eye out for billionaires who travel to the island for a holiday and emerging looking younger and healthier.

Supply Side Health Care Reform

We fight over health care policy because we focus on demand and redistribution. We could reach greater agreement if we focused on supply and innovation. What are the key areas where agreement is likely?

1) Cancer kills both Republicans and Democrats so more spending on medical research is likely to reach broad agreement.  As I said in Launching:

Looking at the future, if medical research could reduce cancer mortality by just 10 percent, that would be worth $5 trillion to U.S. citizens (and even more taking into account the rest of the world). The net gain would be especially large if we could reduce cancer mortality with new drugs, which are typically cheap to make once discovered. A reduction in cancer mortality of this size does not seem beyond reach, and the value of such a reduction in mortality far exceeds that of spending more on medical care today. Yet because the innovation vision is not central to our thinking, we overlook potentially huge improvements in human welfare.

By greater spending on medical research, I mean not only greater spending through the NIH but also a commitment to innovation policy more broadly. We know, for example, that price controls kill medical research so no price controls. We can also improve the FDA. I would favor less regulation but there are other methods to speed up the approval process which could command bipartisan support such as greater funding of the FDA. The FDA is also not monolithic, some departments are better than others, so we can reform the FDA by making it more like the better parts of itself.

In thinking about pharmaceutical regulation we also need to remember that 80-90% of prescriptions are for generic drugs and due to intense competition, generic drug prices are low and falling–so lets build on the parts of the US health care system that work well by keeping the entry barriers to entry in the generics market low.

2) Increase the supply of physicians. Despite an aging population and greater demand, the number of MDs per person has been trending downwards! Increasing physician supply could involve a combination of increased immigration of foreign physicians (skilled immigration is really a non-brainer that receives widespread support), increased slots at medical schools and in residency programs (via Medicaid), increased support for allowing nurse practitioners, dental hygienists and so forth and making occupational licenses portable across states. (In addition to making it easier for foreign physicians to come to US patients we should also make it easier for US patients to travel to foreign physicians–patients without borders). None of these things are easy to do, of course, but neither are they riven by ideological differences.

3) Demand price transparency from hospitals and other health care providers. In real markets, a price is a signal wrapped up in an incentive. With few exceptions, we don’t have real markets in health care and so “prices” neither signal nor incentivize. Thus, I don’t expect miracles from “price” transparency and this is a policy that could go wrong but transparency would still allow for some standardization, comparison, and computation of tradeoffs. Price transparency would also limit some of the worst forms of bill abuse. Even the Soviets found prices to be useful for these purposes.

Other supply side reforms that could find bipartisan support?

Reciprocity and Muscular Dystrophy

For years, muscular dystrophy patients in the United States have been purchasing the drug deflazacort — used to stabilize muscle strength and keep patients mobile for a period of time — from companies in the United Kingdom at a manageable price of $1,600 a year.

But because an American company just got approval from the Food and Drug Administration to sell the drug in the United States, the price of the drug will soar to a staggering $89,000 annually, the Wall Street Journal reported last week.

Because the FDA restricts the importing of drugs from overseas if a version is available domestically, patients are stuck with the new, expensive version. This makes deflazacort the perfect case for advocates of international drug reciprocity — a reform that would make it easier for consumers to buy drugs that have been approved in other developed countries.

That is the introduction to an interview with yours truly in the Washington Post. I discuss thalidomide and the race to the bottom argument. Here is one other bit:

IT: Do you have any thoughts about the potential for FDA reform under this new administration and Congress?

AT: Peter Thiel’s speech at the Republican National Convention reminded us that we used to take big, bold risks — like going to the moon. Today, to say a project is a “moon shot” is almost a put-down, as if going to the moon never happened. We have become risk-averse and complacent, to borrow a term from my colleague Tyler Cowen. The result of the incessant focus on safety is playgrounds without teeter totters, armed guards at our schools and national monuments, infrastructure projects that no longer get built, and pharmaceutical breakthroughs that never happen.

The new administration is unpredictable, but when it comes to the FDA, unpredictable is better than business as usual.

The administration has yet to appoint a great FDA commissioner. Early names floated included Balaji Srinivasan, Jim O’Neill, Joseph Gulfo, and Scott Gottlieb but Srinivasan seems to have removed himself from the running. O’Neill would be great but I don’t think the US is ready, so that leaves Gulfo and Gottlieb. My suspicion is that Trump will like Gulfo because of Gulfo’s entrepreneurial experience but, as I said, the new administration is unpredictable.

Frances Kelsey Syndrome

Occasionally I have been told that FDA reform is something that only a few libertarian economists support. But in fact, there is strong support for reform in much of the medical community. See, for example, the survey that Dan Klein and I did on off-label prescribing and FDA reform or the many surveys of physicians done by CEI.

I mentioned Dr. Vincent DeVita in my post, Will Trump Appoint a Great FDA Commissioner? It’s worthwhile exploring DeVita’s views at greater length because he is a prominent figure in the field of oncology. Here, from Wikipedia, is some background on DeVita:

Vincent Theodore DeVita, Jr., MD is an internationally recognized pioneer physician in the field of oncology. DeVita spent the early part of his career at the National Cancer Institute (NCI). In 1980, the president of the United States appointed him as director of the NCI and the National Cancer Program, a position he held until 1988. While at the NCI, he was instrumental in developing combination chemotherapy programs that ultimately led to an effective regimen of curative chemotherapy for Hodgkin’s disease and diffuse large cell lymphomas. Along with colleagues at the NCI, he developed the four-drug combination, known by the acronym MOPP, which increased the cure rate for patients with advanced Hodgkin’s disease from nearly zero to over 70%.

DeVita was the Director of Yale Cancer Center from 1993 to 2003. He is currently the chair of the Yale Cancer Center advisory board and is professor of internal medicine and of epidemiology and public health at Yale’s medical school.

DeVita currently serves on the editorial boards of numerous scientific journals and is the author or co-author of more than 450 scientific articles. He is one of the three editors of the popular textbook (also available online) Cancer: Principles and Practice of Oncology and serves as the editor-in-chief of The Cancer Journal.

In his book, The Death of Cancer, DeVita has a chapter on the FDA. The title of that chapter? Frances Kelsey Syndrome. He writes:

The thalidomide episode sent the message to those who worked at the FDA that the way to do right by people was to say no. Saying yes would prove perilous–not only to patients, but to the careers of a reviewer. As a result, the agency tends to reward those who say no, not yes. (In fact, there’s an annual Frances Kelsey award. But there are no awards for getting a good drug quickly into the public domain.)

Exactly right. Later he discusses another problem that he sees with FDA evaluation procedures:

We are approaching what we might have considered nirvana years ago. We can design drugs that will hit a specific target, and by being so specific, they have fewer side effects. But because effective treatments almost always require hitting more than one target at the same time, some very good and relatively safe cancer drugs show no evidence of effectiveness when used alone.

What a dilemma. After spending millions of dollars developing a drug, a company may be forced to abandon it for lack of efficacy, when, if approved, it would be another exciting tool for clinical investigators who want to explore combinations of targeted therapies in post-market research trials. Compound that with the FDA’s insistence on testing them first on patients with very advanced, resistant disease, and many potentially useful drugs don’t look so good. As a result, drug companies are reluctant to invest money in new cancer drugs, because they might never make it past the FDA’s hurdles.

DeVita may be wrong but he’s certainly not uninformed.

DIY Gene Therapy

As I noted in yesterday’s post, Will Trump Appoint a Great FDA Commissioner?, personalized medicine is a challenge to the FDA. Technology Review has an excellent piece on an extreme version of personalized medicine, DIY gene therapy:

Hanley, 60, is the founder of a one-man company called Butterfly Sciences, also in Davis. After encountering little interest from investors for his ideas about using DNA injections to help strengthen AIDS patients, he determined that he should be the first to try it. “I wanted to prove it, I wanted to do it for myself, and I wanted to make progress,” says Hanley.

Most gene therapy involves high-tech, multimillion-dollar experiments carried out by large teams at top medical centers, with an eye to correcting rare illnesses like hemophilia. But Hanley showed that gene therapy can be also carried out on the cheap in the same setting as liposuction or a nose job, and might one day be easily accessed by anyone.

…Hanley opted instead for a simpler method called electroporation. In this procedure, circular rings of DNA, called plasmids, are passed into cells using an electrical current. Once inside, they don’t become a permanent part of person’s chromosomes. Instead, they float inside the nucleus. And if a gene is coded into the plasmid, it will start to manufacture proteins. The effect of plasmids is temporary, lasting weeks to a few months.

Hanley’s method is painful and doesn’t last long but it’s remarkable that it can be done at all.

At least one additional person who underwent self-administered gene therapy is a U.S. biotech executive who did not want his experience publicly known because he is dealing with the U.S. Food and Drug Administration on other matters.

Hanley says he did not secure the approval of the FDA before carrying out his experiment either. The agency requires companies to seek an authorization called an investigational new drug application, or IND, before administering any novel drug or gene therapy to people. “They said ‘You need an IND’ and I said, ‘No, I don’t,’” recalls Hanley, who traded e-mails with officials at the federal agency. He argued that self-experiments should be exempt, in part because they don’t pose any risk to the public.

Drug Reciprocity with Europe Gains Support

As loyal readers know, I’ve long been in favor of a system where a drug approved in another major, developed country is also approved here. For a long time it seemed as if I was shouting in the wilderness but in the last few years support for the idea has grown, as the Cruz-Lee Reciprocity bill indicates. In A Cure for Swelling Drug Prices: Competition, Greg Ip at the WSJ notes another new development:

Mr. Tabarrok says the FDA should also offer reciprocal approval of drugs that regulators in other advanced countries have already cleared. Imports of generics from countries with government-negotiated prices ought not to be as controversial as patent-protected drugs because they involve far less expensive and risky research. Indeed, the Generic Pharmaceutical Association and its European equivalent, Medicines for Europe, have proposed a “single development pathway” under which approval in one jurisdiction would automatically confer approval in the other.

The proposed plan is for generics only where the issues are simpler but Greg is right to conclude more generally:

The FDA has long insisted, for safety reasons, that it approve all drugs regardless of whether they have been approved overseas. But if the FDA was once a better regulator than its overseas peers, it isn’t now. Ken Kaitin, a professor of medicine at Tufts University who has studied drug regulation around the world, says there is “absolutely no evidence” the U.S. drug supply is safer than in Britain, Canada or Europe.

Thus, the FDA wouldn’t be compromising safety by harmonizing its approvals with foreign regulators. Indeed, by making more drugs available at lower cost, it could ultimately make Americans healthier.

Two “The Rest of the Story” Stories

The rest of the story” stories have a punch line that twists everything that came before into an entirely new and deeper perspective. My favorite such story is about John Nestor.

Nestor became a minor if hated celebrity in the mid-1980s in Washington, DC for his policy of driving on the beltway in the left hand lane at 55 mph, not a mile faster, the rest of the traffic be damned. Nestor believed that the 55 mph speed limit saved lives and he was going to help other people by slowing them down regardless of the exasperation, raised fingers, or honking. He knew better than other people.

The truth, of course, is that it’s actually variance in speed that kills so by driving more slowly than everyone else Nestor was increasing risk not lowering it. But that’s not the punch line. The punch line? John Nestor was an FDA bureaucrat so obstinate that even the overly cautious FDA thought he was a menace and they pulled him from his job in the renal section for not approving a single new drug in more than four years. On the roads or at the FDA, John Nestor illustrated why I say caution can be deadly.

My second favorite story like this comes from a recent article on land use policy by Mark Gimein at the New Yorker:

In 1948, a federal housing bureaucrat named Paul Oppermann, trying to come to terms with the perils of the nuclear age, proposed a solution to the problem of protecting America’s cities from the bomb: empty them out preëmptively by encouraging the population to move to suburbs and small towns of fifty thousand or fewer. “No power in the world could afford to drop an atomic bomb on a city of 50,000 or less” is how the San Francisco Chronicle summarized the talk that Oppermann gave to a local planning organization. Plus, Oppermann explained, you get slum clearance into the bargain.

The punch line? “The next year, Oppermann assumed office as San Francisco’s planning director.” As Gimein notes Oppermann wasn’t able to move people out of San Francisco but he was able to “[cripple] growth with arcane lot-size rules and off-street-parking-space minimums.”

So now you know the rest of the stories.

The Right to Try

Right to Try legislation permits patients fighting a terminal illness to get access to not-yet-FDA-approved drugs. Thirty-one states have passed Right to Try legislation with massive shows of support but so far these laws are untested by the courts so it’s not clear whether they are anything but expressive. The massive support for Right to Try laws, however, suggests that there is demand for a better FDA as Bartley Madden writes:

Freedom is a powerful rallying call and 31 states have now passed Right To Try legislation with sky-high approval ratings by citizens.

…[But] the states do not have the legal authority to circumvent the FDA. Moreover, drug developers have a major disincentive to participate because, to survive, drug developers need to secure FDA approvals for their new drugs. And circumventing the FDA by providing not-yet-approved drugs to terminally-ill patients could easily slow or prevent FDA approvals.

…A better solution is Free To Choose Medicine (FTCM). It would solve the dilemma facing politicians who are pulled in one direction by citizens’ demands for more freedom and in the opposite direction by FDA proponents with demands for a highly-controlled process. A clear, brief explanation of FTCM is available on the Internet in the PowerPoint presentation, “Free To Choose Medicine and Right To Try.” It explains how we will all benefit from more freedom of choice.

First, the Free To Choose track (separate from the FDA’s conventional clinical testing track) enables patients and their doctors to make informed decisions about the use of FDA-approved drugs or not-yet-FDA-approved drugs. Patients, under the guidance of their doctors, would learn about initial safety results and up-to-date treatment results of FTCM drugs. FTCM drugs for a wide range of illnesses (not just terminal illnesses addressed by Right To Try) would be available up to seven years before conventional FDA approval.

Second, FTCM legislation would provide for government oversight of an open-access, Internet-accessible database. It provides up-to-date information for patients and doctors about a FTCM’s drug’s potential benefits and risks before they choose to use it. This is a self-adjusting system wherein more patients use FTCM drugs that work well and vice versa.

The open-access database would contain treatment results of FTCM patients including their genetic makeup and relevant biomarkers. This database (not part of Right To Try legislation) would reveal subpopulations of patients who do extremely well or poorly with the new drug. Pinpointing such groups of patients is a huge benefit to, not only patients, but to biopharmaceutical researchers working on new breakthroughs in medicine.

Third, FTCM federal legislation needs to provide a new type of drug approval – Observational Approval – based on treatment results for real-world patients who receive the FTCM drugs. This would motivate drug developers to participate as well as expedite insurance reimbursement for patients.

Naturally, I agree with Bart on the need for FDA reform.
