Pharamaceutical FUD (PHUD)

Category: Politics — @ 6:14 am

A few weeks ago I, one stormy night, I went to the theatre to see Serenity. I canít say I am a huge Joss Whedon fan because, well I have never watched a Buffy Episode in my life. But a number of the Firefly episodes landed on my computer and even since I became hooked. I liked the characters and a sci-fi with a Western twist added an extra layer of grit to an already compelling plot.

The night I went to see the movie, I was working on a conference paper on psychiatry and the pharmaceutical industry. As is typical with me, I felt a little guilty that I was slumped in a big cushy movie theatre chair, stuffing myself with popcorn, and not hunched over my computer. So when the movie turned to the issue of pharmaceuticals, my guilt vanished as I felt this movie was part and parcel on my paper: the nature of public critique and debate over the authority psychiatric pharmaceuticals.

For those who have seen the movie, the reference to the dangers of some current psychiatric pharmaceuticals was quite obvious. At the end of the movie, the crew of Serenity finds themselves on some remote planet, past the really icky and creepy reevers. There they find a deserted planet. But actually on closer inspection, it is deserted only because it is filled with dead people. They discover some video projected computer program that reveals everyone has died of extreme apathy and complacency, which was a result of a drug, Pax that was, if I remember correctly, put in the water. People were so chilled out on the stuff, they basically stopped doing everything and died. But if Pax killed people by transforming them as totally passionless, one class of folks, however, reacted quite differently to Pax. They became insanely violent and like to eat people: yes the reevers.

The reference to Paxil is far from subtle. The drug has been mired in controversy in the last number of years. In fact, so much so, that among other lawsuits, investors alsosued claiming that Glaxo concealed the suicide risks Paxil carries.

This comes at the heels of other revelations that Big Pharma has concealed important data, the most famous being the cardiac dangers of a class of painkillers like Vioxx. To me, it seemed due to these events, there is a more critical stance toward pharma, and that perhaps the FDA would be a little more stringent in overseeing the drug approval process.

Apparently not.

So this article from the Washington Post
U.S. Alters Test Policy On Psychiatric Drugs: FDA Won’t Require 6-Month Studies
, actually came as a great surprise. And if you donít believe me, read the article yourself: the logic is often backwards and filled with FUD. The Pharma version of FUD (PHUD) is served straight up in the article:

They also warned that the policy would cause drug companies to scale back on developing new drugs because of the potential increase in expense and risk.

Now I don’t toe a Scientology-like position where all psychiatric drugs are evil. There is a place for them, and there is a need to develop better drugs, especially given the side-efffects of so man y of them But what is clear, given these drugs, many of which are used on younger and younger kids, more caution and regulation would seem like the more prudent thing to do.

The government will back down from a plan to require long-term studies of new psychiatric drugs before allowing them on the market, regulators said yesterday.

The reversal of the recently adopted policy came after a panel of experts unanimously recommended against requiring such studies as a condition of approval. While such studies are needed, the experts said, delaying decisions on new medications would hurt patients.

The panel’s vote came after it heard a barrage of complaints from industry executives, academic researchers and patient advocates. All the critics predicted that the policy would lead to delays in bringing new drugs to market while providing little new information that may not apply to most patients. They also warned that the policy would cause drug companies to scale back on developing new drugs because of the potential increase in expense and risk.

The new plan, which the Food and Drug Administration had begun to implement over the past six months, called for companies to conduct studies for as long as half a year before seeking approval of new drugs. Like many other medications, psychiatric drugs are typically approved on the basis of positive results from two short-term studies, each of which may last only eight weeks.

Because physicians routinely prescribe psychiatric drugs for much longer periods, the FDA had started demanding longer-term data, as do regulators in the European Union, said Thomas P. Laughren, director of FDA’s Division of Psychiatry Products. After the emphatic rejection by the panel yesterday, Laughren said regulators will “back off.”

Criticism of the plan was voiced in all 15 presentations made at the panel meeting yesterday, prompting the chairman of the advisory panel, University of Florida psychiatrist Wayne Goodman, to implore his fellow scientists to mount an argument in favor of the requirement, if only to play “devil’s advocate.” But all the panelists agreed with the academic researchers, patient advocates and industry executives from Merck and Co., Wyeth Pharmaceuticals, Eli Lilly & Co. and other companies in stressing that the new federal requirement would have adverse consequences.

In the real world, as many as half of all psychiatric patients switch medications after three months of treatment, and as many as 70 percent switch after six months, said David Michelson, executive director for neuroscience medical research at Eli Lilly, which makes Prozac and other psychiatric drugs.

Asking companies to conduct trials that show that medications work for six months or longer will lead to trials that focus on the small subset of patients who do well for such long periods, rather than on the majority that do not, Michelson and others said.

As a result, added Gary Sachs, a Harvard University researcher who testified at the meeting, such data will be of little help to clinicians in the real world who usually have to deal with less predictable cases.

“I believe the public interest is not served by this requirement, and it could cause a lot more harm and confusion than benefit,” Sachs told the panel. “It would be telling someone with a heart attack that we have a drug that we know works, but we can’t give it because we don’t yet know whether it would prevent further heart attacks.”

Sachs and other experts said “effectiveness studies” that can guide clinicians about which drug to try first, and when patients should stop taking a medication, are very valuable — but their complex design and requirements mean they are best conducted at public expense by research institutions such as the National Institute of Mental Health.

While that institute does fund such studies, Sachs said, “their commitment to do that is substantially less than we would wish.”
