In an op-ed piece in the Wall Street Journal Scott Gottlieb, a former FDA official under George W. Bush, argues that the FDA should cease requiring healthcare device companies to use sham procedures when they test particular new goods. To assistance his argument he utilizes the illustration of renal denervation, a once highly promising new engineering for reducing blood stress. Unfortunately, Gottlieb extracts exactly the wrong lesson from this story, because the renal denervation story is a perfect example of why sham procedures can be each required and far more ethical than any option.
At very first glance it is tough to disagree with Gottlieb. The idea that patients would acquire an invasive surgical process that could do no great appears abhorrent. “Research that introduces harm or danger with no chance for advantage would seem to be to conflict with the ideas governing investigation on humans,” writes Gottlieb.
But the exact same actual phrases could and must be utilized to describe medical gadgets with no established advantage. In such instances, even so, instead of the reasonably modest quantity of patients possibly exposed to harm in clinical scientific studies, the variety of patients exposed to harm in the real world could be larger by many orders of magnitude.
Let’s examine this issue utilizing the exact same instance utilised by Gottlieb: renal denervation. In situation you haven’t been following this story, for the final handful of years renal denervation– the zapping of the renal artery with electric power to reduced blood pressure– has been widely deemed to be a single of the most thrilling and promising new healthcare technologies around. Based mostly on preliminary– and uncontrolled– scientific studies renal denervation was believed to constantly lower blood pressure by an astounding 25-thirty mm Hg and was hailed by several hypertension experts as a potential breakthrough remedy for people who had persistently and dangerously higher blood strain even right after taking a number of blood strain drugs.
Then actuality intruded. Medtronic announced last month that its pivotal trial of renal denervation had not met its main endpoint. It grew to become clear that renal denervation was neither a remedy nor a breakthrough. Although the particulars of the trial have not been revealed, the underlying trigger of the trial’s failure is reasonably nicely understood. Final summer a few skeptical British researchers very carefully examined the underlying science and concluded– contrary to what market and the professionals had been saying– that the correct blood strain decreasing result of renal denervation wold be a lot smaller sized than predicted. And the cause was straightforward: since all the early research had been either uncontrolled or poorly controlled, the firms and the researchers had tremendously overestimated the real result of renal denervation. The Medtronic trial, by contrast, was a lot more rigorous, in element because it integrated the notorious sham procedures decried by Gottlieb.
As Gottlieb notes, renal denervation “is already obtainable in Europe, where regulators authorized it primarily based on classic research.” Gottlieb fails to recognize how this undercuts his stage. Following all, several 1000′s of men and women in Europe have acquired a gadget from which they may possibly have obtained no or minor advantage and may have seasoned harm. But this does not appear to concern Gottlieb. Right here, creating about the impact of effectively-managed trials, is what does concern Gottlieb:
All of this raises development costs—and it encourages firms to skip the U.S. industry and commercialize new items overseas. This can suppress innovation. When a sham trial doesn’t produce positive final results, the organization may possibly have exhausted its assets and have no capital left to refine a excellent idea into a beneficial product.
But, as the renal denervation story demonstrates, the trial did not “suppress innovation.” As an alternative it showed that the so-referred to as “innovation” was, effectively, a sham.
Even though he waves the flag for ethics, it is clear that what truly motivates Gottlieb to stand up and salute is organization revenue. He’s far far more interested in the overall health of businesses than he is in the well being of individuals. If he were in fact interested in the welfare of sufferers he would spend consideration to the medical particulars of his examples. But rather his genuine concern appears to be the overall health the’ bottom line.
This isn’t the first time Gottlieb has baffled ethics and economics. In 2012 he wrote about another new health-related technology, transcatheter aortic valve substitute (TAVR), and argued that the FDA and CMS had prevented the American public from benefiting from the process. As I wrote then, Gottlieb fully ignored the complicated issues of the story, spinning an untrue but compelling tale in which the forces of government were preventing desperately sick folks from getting a new daily life-conserving therapy.
It seems clear that Gottlieb has really small interest in a critical discussion of clinical trials or the best way to check and introduce new medical technological innovation. What he really desires is to offer a basis for campaign slogans that undermine the FDA and government involvement in medicine. It does not matter that sham surgical treatment is a complex issue or that TAVR had as considerably possible danger as advantage. It’s simple to score polemical factors by scaring people, telling them that they will be subject to damaging procedures or that their government is preventing them from acquiring existence-conserving remedies. It’s a lot harder, and less politically advantageous, to take into account the full complexity of these problems.

“Those who can’t don’t forget the past are condemned to repeat it”.
There are several examples the place the “scam” of some gadget-primarily based therapies has been exposed by the “sham” process. How can any person forget the traditional examples of laser TMR (TransMyocardial Revascularization) or Pacemaker for hypertrophic cardiomyopathy, both touted as breakthrough interventions. It would not surprise me a single bit if RF ablation for atrial fibrillation ends up with a similar fate!
