Clinical Psychology and Psychiatry: A Closer Look

New American Psychiatric Association Prez: We Want Money

2009-06-19T10:59:00.000-07:00

In a recent speech, incoming American Psychiatric Association president Alan Schatzberg was quoted as saying:

"As the recent attacks on APA and leaders of the profession have occurred, it has struck me that some of the detractors in the press have voiced concern that some folks have earned too good a living, often by doing presentations," he said. "I have heard from colleagues and directly from one reporter asking me about one of my colleagues having too high an annual income. I can assure you these detractors would not ask the same question of a surgeon or radiologist earning 10 times the amount paid our colleagues. None of us do what we do for money. Yet, it is also time for us to realize that our members and residents have never taken vows of poverty, and the complexity of the work deserves to be recognized. We need to ask ourselves how we have contributed to our own devaluation with which others seem to resonate, and we need to reverse the course. The rewards for our dedication should not be limited to a sense of pride, but we are also entitled to be paid commensurate to the challenge.

So Schatzberg must be diving into dumpsters, begging at interstate off-ramps, and the like. Oh, wait a minute. This is the same Alan Schatzberg who in 2007 owned close to 5 million shares of Corcept (which translates into roughly 5 million dollars). I have no idea how many shares he owns currently. Corcept, in case you missed it, has shown its drug mifepristone (aka RU-486: "The Abortion Pill") is ineffective in relieving depression among patients with psychotic depression. Schatzberg, at one time, was the chief scientific officer of Corcept and was also the cofounder of the company. According to Corcept's website, he is still a scientific advisor. Despite the stuides of mifepristone showing negative results, the results were spun in a manner to make them sound as if they were positive (1, 2, 3, 4). In a press release, Schatzberg was quoted as saying that mifepristone "may be the equivalent of shock treatments in a pill." Right, with all of the negative studies, it's definitely shock treatment, meditation, and running a marathon all wrapped together in a capsule. Should he be paid "commensutate to the challenge" of trying to weave positive findings from negative results? I don't know what role, if any, he played in the misleading publications surrounding mifepristone. But in his role as chief of the scientific advisory board, I'd venture a guess that he had some involvement. But worry not, the negative results were not spun into positive findings for the sake of money, but for an altruistic love of patients with depression. I'm touched.

Schatzberg was also busted by yours truly putting his name on a duplicate publication that pimped Cymbalta, Lilly's antidepressant. The study presented data from the same set of patients who were involved in a previously published Cymbalta study. Scientific results are not meant to be published in nearly identical form in two different journals. But that didn't stop Schatzberg and his coauthors. If you've not read the lengthy post on this topic, please feel free to check it out in order to understand my cynicism regarding his recent speech.

Another quote from his talk:

We need to sit down with industry and come up with ways of interacting that are acceptable to both sides and fit with future guidelines. I have pledged to follow up on recent initiatives and work with Dr. Scully [APA's medical director] and our Board of Trustees to effect a new partnership—a partnership we can be proud of for what it contributes to the well-being of our patients and our profession.

I can only wonder what type of mutually agreeable interactions would meet Schatzberg's standards. Duplicate publication, serving as a scientific advisor for a company that writes scientifically dubious papers? And it appears that he's encouraging psychiatrists to be greedy -- take the money and don't feel bad about it. Taking industry money is perfectly acceptable in some instances, but it needs to be transparent, and there are plentiful examples of academics getting paid by industry and slanting science in a sponsor-friendly way.

And the clincher:

"The time has come," he said, "to be proud of what we do and to advocate for what we and our patients justly deserve."

Right, psychiatrists deserve to make as much money as possible bending science for corporate sponsors -- and they should be proud of it too. Am I being too cynical? Maybe. But when a guy with Schatzberg's record starts talking about psychiatrists needing to rake in more money from industry, it makes me think I'm living in Bizarro World. Get ready, APA memebers; it's going to be an interesting ride.

Greedy and Ghostly Scientists

2009-06-12T06:09:00.000-07:00

Story one: Zachary Stowe, psychiatrist at Emory University becomes Charles Nemeroff, Jr. Read all about it the Carlat Psychiatry Blog and University Diaries. And check out the WSJ Health Blog as well. The gist is that Stowe apparently did not report all of his external income from his many pharmaceutical industry gigs. Better yet, he was a frequent speaker for GlaxoSmithKline, which had the gall to cancel two of his commercial talks. He then wanted GSK to pay him even though he wasn't going to give the speeches. Read the relevant emails toward the bottom of this document. After reading about Stowe, refresh your memory about Golden Goblet Lifetime Achievement Award Winner, former Chair of Psychiatry at Emory University: Charles Nemeroff. Is there something in the water at Emory? Or is that just how we roll in modern academic psychiatry? Stowe is hereby nominated for a coveted Golden Goblet for his string of emails in which he attempted to shake down GlaxoSmithKline. Sometimes I think that the only thing worse than drug companies are the narcissistic academics who they employ as "key opinion leaders." Not all key opinion leaders are jerks; some are probably even able to reasonably balance their industry cash with being good scientists. But Stowe didn't really portray himself as Mr. Nice Guy in his string of soon to be infamous emails.

Oh, and this little gem:

"Especially disturbing is an email between employees at GSK and a public relations (PR) firm that the GSK hired. The email was titled “For your review/Paxil Breast Milk Press Release” and states:

"[P]lease review the attached press release and forward me any comments/edits.
As you may know, Dr. Stowe is on board for publicity efforts and NAME
REDACTED and I are coordinating time to meet with him next week to arm him
with the key messages for this announcement, which is slated for early February.
We are sending the release for your review at the same time in efforts to secure
distribution on Emory letterhead (as you know, would provide further credibility
to data for the media)."

In his testimony, Dr. Stowe confirmed that the press release was written by the PR
firm and concerned his research on Paxil and its presence in breast milk. He also
explained that placing the press release on Emory letterhead, as opposed to GSK letterhead, would make the data more credible to the public."

If I have this straight, Stowe was willing to place a press release written by a PR firm hired by GSK on official university letterhead to enhance its credibility. Apparently he wasn't concerned about his own credibility. Read the full document of Senator Charles Grassley's investigation of Dr. Stowe.

Part 2: Enter the Ghostwriters

One snippet, then go to Bloomberg for the rest:

Ensuring that medical journal articles presented Zyprexa study results in a positive light was one way for Lilly to reach its sales goal, company officials said in its plan, according to the documents. To do that, Lilly officials hired ghostwriters to prepare submissions to journals such as Progress in Neurology and Psychiatry, according to the unsealed documents. “The paper for the Progress in Neurology and Psychiatry supplement has been completed and sent to the journal for peer review,” Kerrie Mitchell, an employee of the public relations agency Cohn & Wolfe, wrote in a Feb. 23, 2001, e-mail to Michael Sale, a Lilly marketing official. The message was among the unsealed files. “We ‘ghost’ wrote this article and then worked with author Dr. Haddad to work up the final copy,” Mitchell said in the e- mail. Eric Litchfield, a spokesman for Cohn & Wolfe, didn’t immediately return a call requesting comment.

The Bloomberg story is based on a recently released set of internal Lilly documents. That's right -- more Zyprexa documents are on the loose. And the first round of documents provided some good stuff (1, 2, 3), so I can't wait to see what kind of chicanery will be revealed by the latest round. In one sense, it's not exactly news that Lilly ghostwrote Zyprexa papers. We all know that ghostwriting is rampant. How else do key opinion leaders get their names on dozens of papers per year when they are also flying around the country pimping drugs, holding administrative meetings, and doing all sorts of other tasks? But it's nice to have it officially documented that Lilly was playing the ghostwriting game with Zyprexa.

Abilify for Depression: Patients Give it an Oh-For-Three

2009-06-09T04:17:00.000-07:00

Abilify for depression: you've seen the ads. You've hopefully read this blog (1, 2) and the excellent series in the LA Times from Melissa Healy. The advantage over placebo is nothing to get particularly excited about. Especially from the patients' point of view. As I have mentioned previously, the two studies that were touted by key opinion leaders are supporting the efficacy of Abilify for depression suffered from a number of problems. Most germane to this post, the patient self-report rating scales did not indicate a significant advantage for Abilify in either study.

Well, yet another Abilify for depression study is out in CNS Spectrums and guess what... Still not a significant advantage over placebo according to patients. So in each of three large studies, Abilify has failed to beat a placebo according to patients' self-report. These three trials are the basis for the massive marketing campaign and an FDA approval. Abilify started off as an also-ran antipsychotic. But times have changed. Bristol-Myers Squibb's CEO prophetically stated in 2004 after Abilify's approval as a treatment for bipolar disorder:

This approval underscores our commitment to delivering innovative solutions that address unmet needs for a broad spectrum of patients with mental illness, as well as their families and health care providers.

He could as easily have stated: "This approval underscores our commitment to rebranding our unpopular antipsychotic as a Swiss Army Knife/broad spectrum psychotropic that treats everything under the sun. If I can get the FDA and the public to believe that this akathisia-inducing bottom feeder can treat depression, then I'll be LOADED, BWAAH, HA HA HA HA!!!"

OK, maybe he didn't actually say any of those things, but his "broad spectrum" comment was literally right on the money. Just don't ask those pesky patients what they think; they might tell you it's no better than a damn sugar pill.

Yes, I'm aware that on some other rating scales, Abilify was rated as superior to a placebo, but I'm thinking that if the patient self-report of depression is consistently not favorable for Abilify, then who are we kidding by calling it an antidepressant?

Pseudoscience, Candy, and Lamar Odom: Brought to you by Daniel Amen

2009-06-03T05:56:00.000-07:00

If you follow professional basketball, you've probably noticed that LA Lakers forward Lamar Odom has a well-deserved reputation for inconsistent play. When he's good, he's close to amazing, and when he's bad, he's of little use to his team. So how is this related to mental health? Does he have social anxiety disorder? No, get out of Ricky Williams mode and pay attention...

Odom eats candy. Lots of it. And that's why his play is inconsistent. At least that's the story according to Dr. Daniel Amen, who, according to the Los Angeles Times stated:

Odom freely confesses that he just can't help himself when it comes to the sweet stuff and always keeps a stash on hand of Gummi Bears, Honey Buns, Lifesavers, Hershey's white chocolate, Snickers bars, cookies and more. He eats the sugary snacks morning, noon and night, and even says he sometimes wakes up in the middle of the night, chows down on some treats, then falls back asleep.

This is bad news for the Lakers. I've been telling my patients for years that sugar acts like a drug in the brain. It causes blood sugar levels to spike and then crash, leaving you feeling tired, irritable, foggy and stupid. Eating too much sugar impairs cognitive function, which may explain why Odom doesn't always make the smartest decisions on the court. . . .

As a fan and a physician, it concerns me that our professional sports organizations and players are not more concerned about brain health, which includes nutrition. My advice to Odom and to all sugar addicts is to get your sugar consumption under control. You'll feel so much better and your brain will function better too. And, maybe the Lakers can get their 15th championship and Odom can get his first.

Now, remember that Odom's play is inconsistent, not consistently bad. And if he is eating sugar all the time, shouldn't his play be consistently poor? Oh, and is there any science at all to support the idea that eating sugar impairs athletic performance...? I'll admit to not being a top expert on this, but my brief search of PubMed did not bring up anything to support Dr. Amen's suggestions.

So who is this Amen guy, anyway? He claims that Alzheimer's can be detected early through the use of SPECT brain imaging (single photon emission computed tomography). And he sells vitamins/nutraceuticals on his site which, of course allegedly help to prevent cognitive deterioration. There is sooooooooo much more to read about Amen, and I encourage y'all to head over to Salon to read an excellent debunking of Amen's many pseudoscientific claims.

I've rolled my eyes at this guy for years, but now that he's trying to shoot his witchcraft at the fine sport of basketball, I've hit my breaking point. But what do I know... I mean, Amen apparently wrote that

From the first month that I started to order these (SPECT) scans, I felt that they had a special place in science and that I was led by God to pursue this work

And who am I to argue with a guy who was sent by God to practice medicine. But back to Lamar Odom; he insists that he ate candy for breakfast on the game days in which he played well against the Denver Nuggets. Well, maybe, but I bet a SPECT scan or two would figure out why his performance is inconsistent.

Dr. Amen also has some hot, hot science about the men, sex, and the brain. On The View, of all places. Get ready to cringe.

OK, fine. One more. Dr. Amen can target treatment for ADHD appropriately by... yes, using pricey and unproven brain scans! See below...

Yeah, I know the economy is in very bad shape and possibly getting worse. But for the kind of fantastic investigative journalism we get from the inimitable Philip Dawdy at Furious Seasons, one really should whip out the credit card and make a donation. A summary of his good work is available, and his more recent work on Seroquel is worthy of accolades (1, 2).

Phase V, Abilify, and Vanishing Akathisia

2009-05-07T10:53:00.000-07:00

If you've been reading about Abilify for depression on this site, you've probably noticed that I've been down on Abilify for causing akathisia in a frighteningly high percentage of patients. In two recent trials, akathisia occurred in 25% of Abilify patients compared to 4% of placebo patients. What, exactly, is akathisia? That's still a matter of some debate. Let's turn to a recent Journal of Clinical Psychiatry article on the topic. Entitled "Akathisia: An Updated Review Focusing on Second-Generation Antipsychotics," the paper purports to provide "a review of the literature on the incidence of drug-induced akathisia associated with the use of second-generation antipsychotics (SGAs) and first-generation antipsychotics (FGAs)."

It provides a few different characteristics associated with acute akathisia, including:

"Intense dysphoria
Awareness of restlessness
Complex and semipurposeful motor fidgetiness"

It mentions "...suicidal behavior has been described in patients with akathisia in case reports, both in patients receiving antipsychotic medication and in patients receiving selective serotonin reuptake inhibitors (SSRIs)."A couple of descriptions from another journal:

Increased tenseness, restlessness, insomnia and a feeling of being very uncomfortable
On the first day of treatment he reacted with marked anxiety and weepiness, on the second day felt so terrible with such marked panic at night that the medication was cancelled

So we can all agree that akathisia does not sound like fun.

Now back to the Journal of Clinical Psychiatry review article. What did the authors conclude? "The comparative incidence of akathisia among the newer antipsychotic agents remains poorly characterized." And "...SGAs are generally associated with a lower propensity for movement disorders compared with their FGA counterparts, an emerging body of comparative literature shows that second-generation medications are not completely free from inducing akathisia."

The authors go through a long list of second-generation antipsychotic medications. The drug that receives the least attention is aripiprazole (Abilify). The authors conclude that "in studies comparing aripiprazole with placebo, akathisia rates in the aripiprazole arm were similar in some studies, and higher in others. As with other SGAs, akathisia rates with aripiprazole were lower than those of FGAs." So Abilify causes less akathisia than older medications and it's unclear if it causes more akathisia than placebo. But, wait, wasn't akathisia related to much higher rates of akathisia than placebo in treating depression? Fortunately, the authors had a little trick to erase that inconvenient piece of evidence; they only examined trials trials involving people diagnosed with schizophrenia or bipolar disorder. So the depression studies -- POOF -- vanished, along with their damning data.

Why would the authors want to censor negative data about Abilify? Well, one author is an employee of Otsuka America Pharmaceutical, Inc., and another is an employee of Bristol-Myers Squibb, companies that market Abilify. And the other authors: All but one of them have a financial relationship with Bristol-Myers Squibb. The best part:

Editorial support provided by Maria Soushko, Ph.D., Phase Five Communications, Inc., New York, N.Y., with funding provided by Bristol-Myers Squibb.

So a paper that excludes the most inconvenient evidence regarding akathisia on Abilify had major parts of the writing done by... a medical writer hired by Bristol-Myers Squibb. If one goes to Phase Five's website , the first animation that pops up says "Spinning Your Science Into Gold." I'd say that this article was indeed 24 karat gold. I hereby nominate all authors of the study for a much coveted Golden Goblet Award.

Update: See a related post at the Carlat Psychiatry Blog. A partial quote:

Publishing an article that was carefully crafted to draw attention away from Abilify's main liability was shameful, and is exactly the kind of deceptive editorial practice that we as a society can no longer tolerate.

Abilify Runs Amok, Runs Stealth Safety Campaign in Medical Journal

2009-04-29T05:45:00.000-07:00

Furious Seasons has a rather distressing piece of news from a recent Bristol-Myers Squibb conference call. To sum it up quickly, BMS claims that 10.6% of depressed patients are now receiving atypical antipsychotics. Of those 10.6%, 21.7% are taking Abilify. So that would mean roughly 10-11 in 100 depressed patients are taking antipsychotics and 2 of them are on Abilify. I shudder to think how many are on Seroquel. Or Zyprexa. It made me think of a post I wrote a few weeks ago in which I described the marketing of Abilify for depression. A huge market of depressed people just ripe for the picking.

Going along with this, BMS is pushing back on the issue of akathisa, the side effect that has garnered the drug much bad publicity (at least in the blog world; 1, 2, 3) via a medical journal article that distracts attention from Abilify as an akathisia-inducer. More on that to come soon. Ghostwriters, ignoring contradictory evidence; basically, an attempt to completely obscure the evidence on the topic. It's not the first time BMS has successfully placed a study with major flaws into a medical journal (1, 2). Details will be forthcoming.

David Healy: Marketing, Bipolar, and Biobabble

2009-04-17T05:35:00.000-07:00

In an interview with Chrisopher Lane on Psychology Today's blog, David Healy covers the gamut, including the marketing techniques used to pimp Zyprexa, academic spokespersons/key opinion leaders, and bipolar diagnoses run amok. I've been a fan of Healy's work for a long time, but this interview in particular is captivating. Some will claim that Healy is a "bipolar denialist" -- he states that bipolar is overdiagnosed and that the disorder is entirely misunderstood. The fur will continue to fly on bipolarity for years to come, or at least until drug companies run out of products to push for as "mood stabilizers." In the interest of being fair and balanced, Nassir Ghaemi has a rebuttal to Healy's opinion that is also worth reading.

Though I'm tempted to provide a snippet here, I'll instead direct readers to the interview. After a very interesting interview with Philip Dawdy, and now one with David Healy (and other interesting posts), I am really glad the Psychology Today has Christopher Lane on board. I'm sure some people are not pleased with Lane interviewing two of the more prominent critics of modern psychiatry. Giving both of them an outlet to express their views at length runs the risk of Lane being labeled as a Scientologist, as "antipsychiatry," a pharmascold, and as a general rabble-rouser. Good for him. Nice to see that a fairly mainstream publication is willing to step outside the box.

Abilify Marketing Blitz: Atypical Antipsychotics Gone Wild

2009-04-14T05:49:00.000-07:00

"The results are extremely unimpressive; they just squeak by," says Massachusetts psychiatrist Daniel Carlat, editor of the respected Carlat Psychiatry Report. For a clinician or a patient's family, the difference between those on Abilify and those who took a placebo "would be hard to actually see," he adds.

Dr. Carlat is referring to the comparison between Abilify and placebo in the treatment of depression, a topic I have discussed in depth previously (1 , 2 , 3, 4). The above quote comes from a Melissa Healy piece in the Los Angeles Times that throws a damper on Abilify's parade through depression.

Another Melissa Healy piece from the LA Times starts off as follows:

About a year ago, patients began trooping into the office of UCLA psychiatrist Andrew Leuchter, asking whether an antipsychotic drug called Abilify "might be right for them." Few appeared to be delusional, plagued by hallucinations or suffering fearsome mood swings. Mostly, they were depressed or anxious, and frustrated by the pace of their recovery.

Leuchter wondered what was up: Depressed patients didn't usually seek out drugs used to quell psychiatry's most disturbing symptoms.

What was up, he soon discovered, was spending on a new advertising campaign touting Abilify as an "add-on" treatment for depression. For the first time since the arrival of a new generation of antipsychotic medications -- six drugs called the "atypicals" because they work differently from the earlier generation of antipsychotic drugs -- the makers of one, Abilify, had been granted the legal right to market to a vast new population of patients beyond those with schizophrenia or bipolar disorder.

Here's Bristol-Myers Squibb's advertisement for the drug:

This is classic. BMS notes that two-thirds of depressed patients who take antidepressants will still have symptoms after a course of antidepressants. And they have a point: Antidepressants ain't exactly miracle pills. So the commercial implies that Abilify must be really helpful... But if patients add Abilify to their treatment regimen, then only about 25% of them experience remission of depressive symptoms. Isn't it a bit strange that Abilify is appealing to the two-thirds of patients who still have depressive symptoms after taking an antidepressant and offering them a treatment that will lead to remission for only one-quarter of them? Of course, no studies have compared adding Abilify to adding another antidepressant, adding psychotherapy, adding an exercise routine, or adding anything except a placebo. Oh, and given that Abilify led to remission of symptoms in about 25% of patients, while placebo led to remission in about 15% of patients, um, that's a pretty small difference. And keep in mind that the studies were designed in a manner that was almost sure to find a benefit for Abilify, as I have noted previously.

If Abilify was generally benign, then a relatively small benefit over placebo is acceptable. But, as I mentioned previously, the side effects are troubling. I took issue with a BMS-funded journal article/puff piece that tried to spin side effect data on Abilify:

The authors note that "adjunctive aripiprazole is relatively well-tolerated in patients with MDD." Relatively? Relative to what -- being hit with a baseball bat repeatedly? They note that akathisia occurred in 25% of patients on Abilify compared to 4% of patients on placebo. Restlessness: 12% vs. 2%; insomnia: 8% vs. 3%; fatigue: 8% vs. 4%; blurred vision: 6% vs 1%. The authors report that akathisia resolved in 52% of patients by the end of the study, which would also mean that for 48% of patients with akathisia, they were stuck with it at the end of the study. But don't worry, it's "relatively well-tolerated."

You gotta like any drug that induces akathisia at the same rate that it induces symptom remission. Psychiatrist Doug Bremner had a similar take on Abilify as showing a poor cost-benefit ratio. For a few descriptions of akathisia, see comments at this post on Furious Seasons.

Given the unimpressive scientific data regarding Abilify for depression on one hand and the drug's exploding sales on the other, I was sure glad to see a big paper such as the LA Times note that there really is a controversy here. And if Seroquel receives official FDA approval as an add-on treatment for depression, get ready for the marketing machine to reach a fever pitch. Viva Zyprexa, anyone? Melissa Healy covers the expansion of atypical antipsychotics from schizophrenia and bipolar disorder into depression in an article that y'all simply must read. I'll close with a sad-but-true quote from Yale psychiatry professor Robert Rosenheck:

The story's pretty clear, and pretty embarrassing for the profession of psychiatry, which has allowed itself to be led by marketing," says Robert Rosenheck, a psychiatrist at Yale University who has studied the effectiveness and expanded use of the atypical antipsychotics. "We know now what these companies' strategies are: The number of people with schizophrenia is limited, so the road to profitability goes through soccer moms. They need to market these drugs to ordinary people who have dissatisfactions in life.

Leading Psychiatrist Slammed in Leading Journal

2009-04-03T08:29:00.000-07:00

In the latest American Journal of Psychiatry appears a review of Allison Bass's book Side Effects. As many of my readers undoubtedly recall, the book details the saga of the antidepressant drug paroxetine (Paxil) and the troubled line of "research" used to support its use in children (among other points). The reviewer clearly liked the book, which is not necessarily newsworthy. What is notable is that a book review appearing in perhaps the world's leading psychiatry journal slams a leading member of the psychiatry profession. The reviewer, Dr. Spencer Eth, writes the following:

More recently, psychiatrists have been greeted in the morning with front-page newspaper exposés of huge sums being directed by these same drug companies to the physician leaders of our field. In Side Effects: A Prosecutor, a Whistleblower, and a Bestselling Antidepressant on Trial, journalist Alison Bass has written the powerful story of a leading medication, its manufacturer, and a favored psychiatrist, whose driving force was profit not treatment.

Ouch. Though not naming the psychiatrist directly, it is clearly a reference to Martin Keller, bigwig at Brown University, whose work on one particular study regarding Paxil was the subject of a lengthy prior post. For the collection of my posts related to Dr. Keller, please click here.

Back to the review...

This well-told cautionary lacks the excitement of a novel but instead informs the reader with an actual case study with the real names of psychiatrists we know. We can see exactly how corporate greed, drug-company-sponsored clinical research, and mental health care become a toxic mix that inevitably damages our patients’ well being, our colleagues’ reputations, and our profession’s good name.

It was a refreshing surprise to see Martin Keller's goose get cooked in this review. I don't mean to sound vindictive or meanspirited. Keller has done a lot of work over the course of his career, much of which likely has some redeeming value. That being said, there can be little doubt that some of his "science" is quite dubious. And for a major psychiatry journal to run anything, even a book review, that directly goes after a "key opinion leader" who appears quite culpable in performing bad science -- that's a good sign.

The Vioxx Hit Squad

2009-04-01T05:59:00.000-07:00

"We may need to seek them out and destroy them where they live." The words of a Merck employee regarding people who dared to criticize its bestkilling, er, bestselling painkiller/heart attack inducer Vioxx.

According to The Australian , Merck

...made a hit list of doctors who had to be "neutralised" or discredited because they criticised the anti-arthritis drug the pharmaceutical giant produced. Staff at US company Merck & Co emailed each other about the list of doctors - mainly researchers and academics - who had been negative about the drug Vioxx or Merck and a recommended course of action.

The email, which came out in the Federal Court in Melbourne yesterday as part of a class action against the drug company, included the words "neutralise", "neutralised" or "discredit" against some of the doctors' names.

More about this and similar tales of evil at Before You Take That Pill. You might recall that the superhero team in videos used to train Vioxx sales reps was known as the V-Squad. Perhaps the V-Squad was sent out to "destroy them where they live?" Check out the V-Squad videos here and decide for yourself.

APA Monitor: We Don't Need No Stinking Evidence

2009-03-25T06:02:00.000-07:00

The American Psychological Association publishes two monthly publications for members, the well-regarded journal American Psychologist, and the APA's newspaper, Monitor on Psychology. I've been having issues with The Monitor for as long as I can remember. At times, I think the magazine makes claims that are not at all substantiated by evidence, which really bothers me. Why? Because psychology is supposed to be a science; it is what separates psychologists from life coaches or snake oil salesmen. I usually skim the Monitor for about 30 seconds per month, but when I saw the cover for this month's issue, my intuition told me to look out for voodoo. The title: Brain imaging: New technologies for research and practice.

So I browsed through the glossy pages, looking for something to catch my eye. Then, on page 36, there it was...

A pacemaker for your brain? Electric brain stimulation may give hope to people with unremitting depression

Oooh. Sounded promising, so I gave it my full attention. Keep in mind that this was in the "Science Watch" section. The article begins:

It's about the size of the letter "o" in this sentence and may have the power to lift deep, unrelenting depression.

OK, there's the attention-grabber. It then goes on to describe deep brain stimulation (DBS). Before long, I ran across:

Since 2005, more than 60 people worldwide have received DBS for treatment-resistant mood disorders. For about 60 percent of them, there's a "striking improvement in their symptoms of depression," says Andres Lozano, MD, PhD, a neuroscientist at the University of Toronto who performs DBS surgery.

Well, that practically screams "valid scientific findings," asking a surgeon if his technique works. What was he gonna say, "Nah, I think DBS is a bunch of hooey. I only do it because it pays really well." I'm willing to bet that physicians who practiced bloodletting were also quite confident that the majority of their patients showed "striking improvement," which is why we conduct controlled trials rather than rely on subjective opinion. Later in the article, the author notes that the results from DBS are "dramatic and promising." The author also notes that

A number of other behavioral and mood disorders might also benefit from DBS. Benjamin Greenberg, MD, PhD, a psychiatrist at Brown University in Providence, R.I., is using DBS to treat obsessive-compulsive disorder, with success rates similar to [Helen] Mayberg's and Lozano's. Also similar is Greenberg's claim that OCD people who've had DBS are then able to tolerate and respond to behavioral therapy.

This broad success leads Mayberg to believe that DBS is establishing itself as an important tool for treating disorders that otherwise won't budge.

OK, so Lozano claims that 60% of people make "striking improvement"; what about others? As mentioned above, Helen Mayberg has done some research on this topic. The article describes one of her studies. Here comes the most convincing evidence I've ever witnessed:

The initial trial included six people who met diagnostic criteria for major depressive disorder. The two researchers and their colleagues implanted electrodes in the white matter adjacent to their patients' subgenual cingulate cortexes and fired up their pacemakers. All the patients, who were awake during the procedure, reported a "sudden calmness or lightness," Mayberg and Lozano reported in the paper.
The researchers followed up with the patients by administering monthly depression scales. After six months, four of the six showed significantly fewer depressive symptoms. To make sure they weren't getting a placebo effect, Mayberg and Lozano secretly switched off the electrodes in their best-responding patient. After about two weeks, the patient's scores began to drop. After about a month, his depressive symptoms had returned. The researchers switched it back on and six weeks later he was back up to non-depressive levels.

So the author of the article, based on the subjective opinion of a psychiatrist and a neurosurgeon, along with and an uncontrolled study of six people concludes that DBS:

Has shown "broad success"
"A number of other behavioral and mood disorders might also benefit from DBS"
"May have the power to lift deep, unrelenting depression"
Has shown "dramatic and promising" results

The author threw in a few caveats about side effects (though he essentially gave it a clean bill of health), and also noted that DBS should be reserved for patients with longstanding depression and who have not shown positive results with other treatments. So it stopped short of being a blanket endorsement of DBS, yet it did really make it sound like a fantastic treatment for longstanding depression despite the very meager evidence cited in its support. I often complain about poorly designed studies, suppression of negative data, or misinterpreted results leading to drugs being touted as unrealistically safe and effective. But this article shows that it doesn't necessarily take drug company involvement to pimp a treatment well beyond the scientific evidence.

For all I know, DBS may turn out to be The Holy Grail in treating depression of all shapes and sizes. I cast no aspersions on the researchers mentioned in the article, as searching for ways to treat seemingly intractable cases of depression is doing God's work. But the writer did a horrendous job of overblowing the evidence in favor of DBS. This kind of article feeds the popular notion that psychologists are a bunch of flakes who know nothing about science. The APA Monitor can do much better than this.

Seroquel, Haldol, and The Full Court Media Press

2009-03-20T09:41:00.000-07:00

I was very pleased to have been acknowledged in a recent story in the St. Paul Pioneer Press. The reporter, Jeremy Olson, wrote the following in his story:

An Internet psychiatry blog first raised questions March 2 about the research Schulz presented at the APA conference and why it lacked any of the company's findings."It raises troubling questions when an independent academic author presents results that are in direct opposition to the underlying data," wrote the blogger, an anonymous academic.

He didn't cite my blog by name -- the unwieldy long name which I stupidly chose for the site may be responsible for that -- but I'm nonetheless grateful that my site was acknowledged for its work on this story. He is referencing my post in which I noted that a University of Minnesota psychiatry professor (Charles Schulz) had stated in a press release that Seroquel was "more effective" than Haldol. This was based upon his analysis of data comparing Seroquel to the much older antipsychotic drug Haldol in the treatment of schizophrenia. Yet an internal AstraZeneca analysis found that Haldol was actually more effective than Seroquel. Both the Pioneer Press and the Star Tribune, the two big papers in the Minneapolis-St. Paul area ran stories on the controversy.

When asked about his lavishing of praise on Seroquel in the press release, the Pioneer Press said:

In an interview with the Pioneer Press last week, Schulz defended his research and presentation of Seroquel as accurate and ethical. However, he acknowledged the corporate press release from his APA presentation might have exaggerated in calling Seroquel "significantly superior."
"You know," he said, "I can't disagree with that."

Schulz said the following in the Star Tribune:

In an interview this week, Schulz said the pharmaceutical company never shared its doubts about Seroquel, which went on to become a blockbuster, with annual sales of $4.5 billion today. "I don't recall anybody calling up and saying, oh my goodness, we have this problem," he said. At the same time, Schulz acknowledged that his own study did not really show that Seroquel was more effective than the older drug. "That's a bit of a misunderstanding," he said. "I think the overall message is that it works about the same."

Thanks to a helpful reader, I was able to track down what appears to be Schulz's presentation from 2000. It says "...quetiapine was clearly statistically significantly superior to placebo as well as to haloperidol..." This appears to contradict his statement that Haldol and Seroquel "work about the same." Again, the data from Schulz's presentation don't match AstraZeneca's internal analysis. Schulz is obviously backing away from his earlier praise for Seroquel, for which he deserves some credit. The problem was that Schulz, along with a laundry list of researchers in psychiatry were caught in a tidal wave of unbridled enthusiasm for the atypical antipsychotics, first as wonder drugs for schizophrenia, then as the Next Big Thing in bipolar, then moving into the world of depression and anxiety disorders in the absence of decent supportive evidence.

Interesting sidenote: While Schulz was presenting on the wonders of Seroquel, he was likely quite unaware that AstraZeneca has conducted a study (Study 15) which had found that Seroquel compared unfavorably to Haldol in preventing psychotic relapse among patients with schizophrenia who began the study in full or partial symptom remisison. Furious Seasons has some additional reporting on this study. It is a near certainty that Schulz was not informed about this study's results, as this could have changed his lofty opinion of Seroquel. This points to the problem of researchers relying on data collected by drug companies -- how are researchers to know they are receiving all of the data?

Note to key opinion leaders: If you don't realize it by now, you are pawns. You are being used to place an academic veneer on the marketing of drugs. The drugs that you are marketing as major breakthroughs typically offer little to no benefit over existing treatment and may cause a slew of nasty side effects. Decide if you want to be a scientist or a marketer. Don't try to do both at the same time, because the odds are pretty good that your scientific credentials will end up being tarnished. Just ask this guy. Now that the media are paying much closer attention to the conflicted interests and skewed science that sadly underlie much of psychiatry these days, it would be a good idea to maintain appearances.

Abilify, Depression, and the Memory Hole

2009-03-10T04:46:00.000-07:00

The Primary Care Companion to the Journal of Clinical Psychiatry has a piece on Abilify for depression that illustrates many of psychiatry's woes. Full text of the article is here. The journal published an article titled "Examining the efficacy of adjunctive aripiprazole in major depressive disorder: A pooled analysis of two studies." The paper combines data from two previously published studies which examined the addition of Abilify to existing antidepressant treatment (1, 2). One of psychiatry's big-name academics, Michael Thase, signed on as lead author. I'm hoping that he didn't actually write the paper. Actually, there are eleven authors of the paper, which seems a little ridiculous given that the paper is an analysis of data which had already been collected for two previously published clinical trials. Seven of the authors are employees of Bristol-Myers Squibb (BMS) or Otsuka, which both market Abilify. Wait... If you look closely, you can see my favorite disclosure... In the fine print on the first page...

In case you can't read the fine print: In defense of Thase and the other academic authors, they may have not actually written any of the paper. Much or all of the writing appears to be creditable to Ogilvy Healthworld Medical Education. On their site, they note that they perform:

Clinical Development and Publications Management
Experienced medical writers work closely with authors, editors and publishers to provide our clients with a full range of publishing options.

Whatever BMS/Otsuka paid you for this one simply was not enough. Why? Because whomever wrote this thing did an admirable job of focusing on the positive and completely ignoring the negative.

Erasing the Patient's Opinions: Remember, the article's title states that it examines the efficacy of adjunctive Abilify (adding Abilify to existing antidepressant treatment). So you'd think the article would mention all of the relevant depression data from the two relevant studies. Well, no. In the two stuides which are discussed in the article, patients were assessed on depression using the following measures:

Montgomery Asberg Depression Rating Scale (MADRS)
Inventory of Depressive Symptoms-Self Report Scale (IDS)
Quick Inventory of Depressive Symptoms Self-Report Scale (QIDS)

Using the MADRS, the authors conclude that adding Abilify to antidepressant treatment is more effective than adding placebo to antidepressant treatment. OK, fine, though it's not by a particularly huge margin. Mysteriously, the authors do not even mention that the self-report scales (IDS and its subscale, the QIDS) were used in the two trials. And why would they? In both trials, Abilify was not significantly better than placebo on these measures. A letter to the editor pointed out this glaring weakness in Abilify's claims of efficacy, the response to which was weak:

Noting that Abilify did not outperform placebo on the self-report measure in the trial, he wrote that "this may be due to the lower sensitivity" of the measure. So the drug wasn't the failure -- blame the rating scale instead. The people at BMS picked the scale and when it doesn't give results they like, then suddenly it's a poor measurement of depression. I bet Dr. Berman would not have complained about the instrument had it yielded results in favor of Abilify.

In the publications of each of the two clinical trials, the authors tried to downplay the fact that Abilify was no better than placebo according to patient self-reports. Then, when publishing an analysis that combined the results of the two trials, the authors go a step further by not even mentioning that patients completed a self-report. Right down the memory hole. In my opinion, any reasonable academic author writing about such research would want to note the strengths and limitations of Abilify in treating depression. The lack of benefit on patient-rated measures is a major weakness. Yet several big-time academics signed off on this paper despite its complete scrubbing of negative data. For that, I hereby nominate each author for a coveted Golden Goblet Award. And I credit the ghostwriter at Ogilvy with a fantastic job of serving his/her corporate clients. You, sir or ma'am, deserve kudos for a marketing job well-done.

The instructions for authors who submit to the Primary Care Companion to the Journal of Clinical Psychiatry state: "Conclusions should flow logically from the data presented, and methodological flaws and limitations should be acknowledged." Um, does completely scrubbing negative data count as failing to acknowledge limitations? I can see that the peer reviewers and/or editor really paid close attention to this paper.

Safety: The authors note that "adjunctive aripiprazole is relatively well-tolerated in patients with MDD." Relatively? Relative to what -- being hit with a baseball bat repeatedly? They note that akathisia occurred in 25% of patients on Abilify compared to 4% of patients on placebo. Restlessness: 12% vs. 2%; insomnia: 8% vs. 3%; fatigue: 8% vs. 4%; blurred vision: 6% vs 1%. The authors report that akathisia resolved in 52% of patients by the end of the study, which would also mean that for 48% of patients with akathisia, they were stuck with it at the end of the study. But don't worry, it's "relatively well-tolerated."

Overall, another example of a "research" publication being little more than a puff piece in favor of a drug. With big-name academics signed on as authors to add credibilty and just a fine print mention of a ghostwriter.

I thank an anonymous reader for alerting me to this study.

Seroquel, Weight Gain, And the Pursuit of GAD and Depression Indications

2009-03-06T10:33:00.000-08:00

Jim Edwards at BNET dug through the Seroquel documents and found many instances of AZ employees noting that Seroquel causes weight gain. Yet the company seemed bent on keeping this information hidden. As I mentioned last week, this sure seems a lot like Zyprexa redux, except with more sex scandals and perhaps more buried data. I suggest that everyone head over to BNET and see the details.

Despite all the bad news, AZ is pressing onward with its application for FDA approval for Seroquel in both generalized anxiety disorder and depression. Yikes. I broke the story earlier this week about the "scientific literature" claiming that Seroquel worked better than Haldol in the treatment of schizophrenia, yet internal company data showed Haldol as superior to Seroquel in reducing schizophrenia symptoms. Between discrepant data, the apparent hiding of negative clinical trials and trying to keep doctors distracted from data indicating that Seroquel caused weight gain, I think that Seroquel's luck may have ran out -- my bet is that the FDA won't approve the drug for depression or GAD. But I've been wrong before; the FDA did approve Abilify as an add-on treatment for depression based on pretty flimsy evidence.

Internal Documents Suggest that Seroquel Data Were Not Presented Accurately

2009-03-02T08:23:00.000-08:00

A document dated March 9, 2000 titled "BPRS meta-analysis" shows that AstraZeneca, maker of the antipsychotic drug quetiapine (Seroquel), knew fully that its drug did not relieve schizophrenia symptoms to the same extent as its older, generic competitor haloperidol (Haldol). The document provides results of a meta-analysis, a statistical analysis that combines the results of several individual studies. The authors used the Brief Psychiatric Rating Scale (BPRS) as their main measure of efficacy. The BPRS rates a variety of psychiatric symptoms relevant to schizophrenia. More details on the BPRS can be seen here. A total of ten clinical trials were included in the meta-analysis, which variously compared Seroquel to placebo, Haldol, and several other antipsychotic medications. Four trials compared Seroquel to Haldol. Several subscales of the BPRS were included in the analysis.

When examining the amount of change on the BPRS, Seroquel consistently outperformed placebo, both on the BPRS total score and on several of the BPRS subscales. However, in several analyses, Seroquel was outperformed by Haldol and by risperidone (Risperdal; Janssen's antipsychotic). The document states: "Against 'all doses' of Seroquel, each of the three significant p-values generated was in favour of Haloperidol (Total BPRS, Factor V, and Hostility Cluster). There was no evidence of significant differences between the treatments when Haloperidol was compared to high-dose Seroquel." This is a plain admission that Haldol outperformed Seroquel on several outcomes, but that high dose Seroquel yielded approximately equivalent results to Haldol. Only one trial compared risperidone to quetiapine and the results clearly favored risperidone. The document stated: "Comparisons against Risperidone using all doses of Seroquel showed significant improvements for Risperidone on total BPRS, Factor V scores, and the Hostility Cluster. Against high-dose Seroquel only, the Anxiety item, Factor I, and Mood cluster scores were also significantly in favor of Risperidone." Risperidone beat Seroquel, and did so by a wider margin when a high doses of Seroquel was used.

The author of the document, Rob Hemmings, summarizes the results in a table, which appears below. It is described as such: "The following table is an attempt to simplify the claims that could be obtained from these results. A ✔ is entered for those comparisons where we have a statistically significant benefit, be it with 'all doses' or with high dose Seroquel... A x marks those comparisons where a comparator has demonstrated significant superiority compared to Seroquel."

The table demonstrates that according to an analysis by AstraZeneca employees, Seroquel is only shown to outperform placebo, whereas Seroquel is shown to demonstrate poorer efficacy than several other medications.

Under the heading "Conclusions," the document states, in part:

In terms of generating positive claims for Seroquel, these analyses seem somewhat disappointing. Although some trends in favour of Seroquel were observed in the Factor I and Mood cluster items, there was no evidence in these analyses of a significant benefit for using Seroquel over any of the active agents assessed."

The internal analysis clearly indicates that, based on several clinical trials, Seroquel offered no benefits over the competition in terms of reducing schizophrenia symptoms. Indeed, other drugs tended to outperform Seroquel.

How Can These Data be Managed? Shortly after the internal meta-analysis was completed, AstraZeneca employees discussed how to handle the negative results. An AstraZeneca publications manager, John Tumas, wrote in an email

The data don't look good. I don't know how we can get a paper out of this. My guess is that we all (including Schulz) saw the good stuff, ie the meta-analysis of responder rates that showed we were superior to placebo and haloperidol and then thought further analyses would be supportive and that a paper was in order. What seems to be the case is that we were only highlighting the good stuff and that our own analysis support the "view out there" that we are less effective than haloperidol and our competitors.

It would appear that an earlier analysis provided positive results which did not hold up during the internal meta-analysis. "Schulz" almost certainly refers to Dr. Charles Schulz, a psychiatrist at the University of Minnesota. In a press release from the year 2000, Dr. Schulz was quoted:

I hope that our findings help physicians better understand the dramatic benefits of newer medications like SEROQUEL because, if they do, we may be able to help ensure patients receive these medications first. The data suggest that SEROQUEL is an effective first- choice antipsychotic.

This press release was based on Schulz's presentation at the American Psychiatric Association convention in May 2000. The email from John Tumas discussed earlier noted that a group at AstraZeneca needed to meet soon "because Schulz needs to get a draft ready for APA and he needs any additional analyses we can give him well before then." It is unclear if Schulz ever received the analyses that showed Seroquel was less effective than Haldol. Regardless, in the press release, he was also quoted as saying: "Almost 50 years later, however, many patients are still taking these medications [such as Haldol], even though more effective treatments like Seroquel exist." While he was stumping for Seroquel in a press release, AstraZeneca's internal data painted a completely different picture.

Schulz, in his role as primary author, would typically be expected to demonstrate a solid understanding of the data underlying his presentation. It raises troubling questions when an independent academic author presents results that are in direct opposition to the underlying data. Such issues have been mentioned previously on this site.

The documents regarding Seroquel are available at Furious Seasons. Reporting on other facets of the documents can be found at the St. Petersburg Times, Bloomberg, New York Times, and the Wall Street Journal.

Seroquel Becomes Zyprexa, Part 2. But With More Sex.

2009-02-27T08:36:00.000-08:00

I had a big post on Abilify ready to go for today, but I'll sit on it for a few days because Seroquel is the new Zyprexa, and that is the big news of the week. Well, that and Forest getting probed for allegedly marketing Celexa and Lexapro off-label for depression in kids. But more on that later. In the meantime, check out Jim Edwards' nice piece on the emerging scandal.

Back to the 'Quel. First off, a big-time round of applause for Philip Dawdy at Furious Seasons. He's been covering the unfolding Seroquel mess like a hawk, which is exactly what he did during the days of the Zyprexa documents scandal, which is still costing the admittedly criminal corporation of Lilly billions. According to legal documents, Wayne Macfadden, former U.S. Medical Director for Seroquel, admits to being engaged in sexual relationships with a British researcher at the Institute of Psychiatry (IOP) who participated in Seroquel research. Incredibly, Macfadden was also apparently entangled in a sexual relationship with a ghostwriter who wrote up results of Seroquel studies. The attorneys who are suing AstraZeneca claim that: "The IOP researcher suggested that Macfadden would punish her if she even looked at studies that were favorable to Seroquel's competitors." Better yet, Macfadden was alleged to have "promised sexual favors in exchange for intelliegence on AstraZeneca's competitors." It would seem a relevant conflict of interest to note that one was engaged in sexual relations with the Seroquel Medical Director, wouldn't it? I don't typically care about people's sex lives and am in favor of respecting people's privacy. Except when it is potentially related to poor science and/or poor care of patients.

So that's a little weird. And then... according to the Wall Street Journal, internal documents from AstraZeneca suggest that AZ hid concerns that the drug caused diabetes. Gee, that sounds like a page from the Zyprexa playbook. AZ sales reps were instructed to inform physicians that there was no causal link between Seroquel and diabetes. However, according to the WSJ, "In a 2000 position paper about the safety of Seroquel sent to Dutch regulatory authorities, an AstraZeneca doctor named Wayne Geller wrote that there was a relationship between the drug and diabetes. 'There is reasonable evidence to suggest that Seroquel therapy can cause impaired glucose regulation including diabetes melliutus in certain individuals,' Dr. Geller wrote." Expect a few more stories to appear in the mainstream press followed by AZ doling out decent chunks of change to settle lawsuits. This may kill Seroquel's chances of FDA approval for depression, generalized anxiety disorder, and the common cold (OK, I made that one up). Let's hope the documents make their way to the internet so that bloggers such as myself and Philip Dawdy can dig through and go into more depth than the mainstream press. Just like we did with Zyprexa (1, 2, 3).

Can we call this the Sex-o-quel scandal or is that too cheesy?

By the way, Furious Seasons is currently running a fundraiser. I will be making my donation today, and you should do the same if you are in favor of mental health journalism that breaks important stories and is bold enough to cover a wide variety of important issues, regardless of their level of controversy.

What's Next for Schatzberg?

2009-02-13T11:04:00.000-08:00

An advertisement in the Psychiatric Times (page 34 of .pdf) calls for applicants for the Chair of the Department of Psychiatry and Behavioral Sciences at Stanford University, a position now filled by Dr. Alan Schatzberg. The Stanford Psychiatry Department webpage currently states, in part:

Under the direction of the Chairman and Chief Alan F. Schatzberg, M.D., the Stanford University Department of Psychiatry and Behavioral Sciences, a center for the advancement of psychiatric practice, research and education, has three goals:

To advance the understanding of the etiologies of psychiatric or sleep disorders and to lay the foundation for new treatment development.
To develop innovative treatments and to deliver comprehensive services on a continuum of care to patients in a high quality efficient and compassionate manner.
To train medical students, residents and clinical and research fellows in the science and practice of psychiatry and sleep medicine.

Looks like Schatz is out. I have noted previously that Schatzberg was deeply involved with a duplicate publication that pimped Cymbalta. Schatzberg's close involvement with Corcept, maker of mifepristone (Corlux), has also raised eyebrows. Mifepristone has been an utter failure in clinical trials, but the manufacturer has attempted to spin the data in ways that should be obvious to anyone with a smidgen of critical thinking skills. Charles Grassley has hit Schatzberg as part of the investigation into the tangled web of conflicted interests involving psychiatrists and drugmakers. There is also some evidence that Schatz was involved in the launch of Zyprexa for bipolar disorder.

Schatz is apparently out as department chair. I wonder who will take his place...

Thanks to an alert reader for the tip.

Abilify For Depression: I'm Not the Only Skeptic

2009-01-27T05:52:00.000-08:00

In April 2008, findings were published in the Journal of Clinical Psychopharmacology which claimed that the atypical antipsychotic aripiprazole (Abilify) was an effective add-on treatment for depression. I heartily disagreed with the study's conclusions, noting that the patient-rated depression measure did not demonstrate an advantage over placebo, an inconvenient result that the authors tried to explain away as if was unimportant. I also pointed out that the study design was biased in favor of Abilify:

Study Design. Patients were initially assigned to receive an antidepressant plus a placebo for eight weeks. Those who failed to respond to treatment were assigned to Abilify + antidepressant or placebo + antidepressant. Those who responded during the initial 8 weeks were then eliminated from the study. So we've already established that antidepressant + placebo didn't work for these people -- yet they were then assigned to treatment for 6 weeks with the same treatment (!) and compared to those who were assigned antidepressant + Abilify. So the antidepressant + placebo group started at a huge disadvantage because it was already established that they did not respond well to such a treatment regimen. No wonder Abilify came out on top (albeit by a modest margin).

Here's an analogy. A group of 100 students is assigned to be tutored by Tutor A regarding math. The students are all tutored for 8 weeks. The 50 students whose math skills improve are sent on their merry way. That leaves 50 students who did not improve under Tutor A's tutelage. So Tutor B comes along to tutor 25 of these students, while Tutor A sticks with 25 of them. Tutor B's students do somewhat better than Tutor A's students on a math test 6 weeks later. Is Tutor B better than tutor A? Not really a fair comparison between Tutor A and Tutor B, is it?

Some commenters agreed with my take on the matter while others did not. Two letters to the editor published in the latest Journal of Clinical Psychopharmacology raised concerns about the study. Alexander Tsai, from UCLA, wrote that he was concerned that the advantage for Abilify was small (2.8 points on the Montgomery-Asberg Depression Rating Scale ) and that the study design was biased in favor of Abilify (agreeing with my earlier point).

Dr. Bernard Carroll, wrote in his letter that:

The advantage of Abilify over placebo was small
There was no advantage on the patient-rated measure
Due to the notable side effect profile of Abilify, clinical raters could likely distinguish patients who were taking Abilify from those who were taking placebo, which could have biased their ratings. Thus, he questions if the study was truly double-blind.
The authors did not report whether the occurrence of several side effects were more common on Abilify than placebo. Dr. Carroll calculated that akathisia, fatigue, restlessness, and insomnia were all significantly more common on Abilify and wondered why the authors did not include such data in their report.
The authors did not note the relationship between akathisia (severe restlessness/tension) and suicide, which is concerning given that Abilify produces akathisia in droves.

The Defense: Robert Berman from Bristol-Myers Squibb wrote back to defend the study. His points were not impressive. Noting that Abilify did not outperform placebo on the self-report measure in the trial, he wrote that "this may be due to the lower sensitivity" of the measure. So the drug wasn't the failure -- blame the rating scale instead. The people at BMS picked the scale and when it doesn't give results they like, then suddenly it's a poor measurement of depression. I bet Dr. Berman would not have complained about the instrument had it yielded results in favor of Abilify.

Adverse Events: As for not reporting adverse events, well, there's a perfectly good explanation hidden somewhere in here...

...we have clearly reported rates of spontaneously reported treatment-emergent events that occurred at a rate of 5% or greater in any treatment group. As this study is not designed to collect adverse events in a systematic manner, statistical comparison between treatment groups is not appropriate.

So let me get this straight. They discussed "spontaneously reported" events, which would refer to the events reported by the patients without much questioning. Everyone knows that spontaneous reports are a joke because most side effects are not spontaneously reported. Based on spontaneous report, the rate of sexual side effects in SSRI's is quite low. But when you bother to ask people taking SSRIs questions about their sexual functioning, the rates of sexual problems increase drastically. So when Dr. Berman goes on to write that no suicide-related adverse events were reported in the study, keep in mind that the study investigators were not asking about such events. So it may be more accurate to say that nobody committed suicide during the study, but nobody was tracking suicidal ideation unless patients reported such problems themselves. Yes, suicidal ideation was covered a little bit by measures used in the study, but a more systematic assessment would have been helpful. To give the authors credit, at least they did include a couple measures of extrpyramidal symptoms, from which we gathered that akathisia happened in 25% of patients. Yikes.

Saying that the study was not designed to collect adverse event data in a systematic manner is frightening. If adverse event collection was not systematic, then the authors writing in the study report that "adverse events were generally mild to moderate" is meaningless. You can't say that adverse event data were not collected in any sort of systematic manner then also say that the study is "safe," as the authors claim in their paper. This is the definition of duplicitous. In any case, the authors should have reported that several adverse events were significantly more likely to occur on Abilify than placebo rather than making the ridiculous claim that comparing adverse event rates between treatment and placebo is not appropriate.

Dr. Berman does not address the less than 3-point benefit for Abilify over placebo. There is also no real explanation to address the concerns of Dr. Tsai and myself, who noted that the study design was biased in favor of Abilify.

Kudos to Dr. Caroll and Dr. Tsai for taking the time to write excellent letters which addressed quite problematic issues in this study. Every time I see a commercial pimping Abilify for depression, I cringe. It's good to know that some people in the medical community are seeing through the weak research that "supports" the use of Abilify as an antidepressant.

Zyprexa: Lilly Admits Guilt, But Also Blame Physicians

2009-01-16T07:33:00.000-08:00

In February 2007, I wrote a post in which I described evidence that Lilly's antipsychotic olanzapine (Zyprexa) was marketed off-label for dementia. The evidence I discussed was based on documents generously and bravely hosted at Furious Seasons. At the time, I was careful to avoid labeling the practices as illegal -- they were definitely unethical but I couldn't really say for sure what if a law was broken. However, a law firm known to represent Lilly was regularly visiting my website at the time, which made me think that Lilly was seriously concerned about legal troubles. I suppose they had good reason to be worried.

I can now officially say that the off-label marketing of Zyprexa for dementia was criminal. Lilly just admitted to committing a crime in the off-label marketing of the drug for dementia and settled legal charges for a cool $1.4 billion. And there are more cases still on the books.

For a really interesting take on this situation, listen to New York Times reporter Gardiner Harris. You can find his talk embedded in the New York Times story from January 14, 2009, which is linked here. The plea agreement in the latest case is available here.

It is important to remember that pimping Zyprexa for dementia is far from a victimless crime. Antipsychotics, including Zyprexa, have been linked to an increased rate of death in elderly patients and have also been shown to be of little to no more benefit than a placebo in reducing dementia-related symptoms (1, 2). For a disturbing account of the widespread inappropriate use of such medications, read this post and weep.

This is truly a case where lust for profits likely led to the early demise of who-knows-how-many patients. And we're just talking about dementia, not the other cases where Lilly went berzerk with marketing Zyprexa (1, 2).

Blame the Physicians Too: While much of the blame for the overuse of antipsychotics in the elderly can be placed on corporations such as Lilly, it is also true that Lilly does not directly administer the drugs. Physicians need to understand that prescribing drugs which have been found to offer little benefit but are linked to killing patients -- how is that legitimately practicing medicine? First, do no harm?? Yes, I know that dementia is a hell of a difficult condition to handle. But does that mean we should be doling out ineffective and potentially deadly treatments to "manage" persons with dementia. Yes, reps from Lilly (and likely others) wined and dined physicians, "educating" them about the benefits of Zyprexa and other antipsychotics. That's their job -- to positively spin their products. No different than a used car salesperson except that drug reps are typically much better looking.

Doctors need to use critical thinking skills -- you don't just listen to a drug rep or skim a drug-company provided journal article reprint then jump on the Zyprexa bandwagon. How about learning how to evaluate evidence so that junky marketing disguised as science does not persuade you to write inappropriate scripts? Yes, we can be outraged that Lilly and others pimp ineffective and dangerous treatments, but the physicians are the most important link. If they cannot be better educated to understand clinical trial results, and cannot take time to critically review the scientific literature, then this pattern will repeat itself over and over again. It takes tricky pharmaceutical marketing in combination with an audience that is unwilling to think critically for this type of tragedy to occur. And occur again, it will.

Unfortunately, the published scientific literature is quite biased, as negative studies tend to vanish rather than grace the pages of our journals. But it's still a much better idea for prescribers to actually read journals and critically examine their findings, as opposed to relying on marketing alone. Better yet would be for research data on medications (negative and positive) to be available for all to see.

The Budget Crisis, Universities, and Key Opinion Leaders

2009-01-12T05:47:00.000-08:00

Everyone knows that state budgets across the United States are in a crunch. All state-supported universities are looking for sources of income outside of taxpayer funds. As state legislatures look to cut money, many state universities are in for a big budget hit. So if the state is going to pony up less money, how can a university survive...?

Perhaps by seeking to entice industry funding. Set up a few clinical trials and see what happens. There is nothing inherently wrong about university faculty working on industry-sponsored research. In an ideal world, all goes according to plan and all benefit from such collaboration. Universities love industry collaboration because it brings in good money. Researchers like to collaborate with industry for some altruistic motives, such as receiving funding to work on investigating treatments that might hopefully bring about better lives for people struggling with various ailments. Because receiving funding makes the university
administration happy, it also makes life at a university medical center much more pleasant for those who bring in the bucks.

But how do things really work? Sometimes, they go well. But there are also nondisclosure agreements, in which an "independent" academic researcher gives away any right to discuss the data from clinical trials that he/she is working on unless approval is given by industry. As Graham Emslie, key opinion leader in the field of child psychiatry, can attest to, there are certainly many cases where negative results were found for a drug, but the negative data were buried to avoid any untoward publicity. Academics often farm out their writing of joint work with industry to ghostwriters who spin the final product to pimp a product rather than accurately describe the results. As regular readers know, this is just the tip of the iceberg.

If academics are willing to be oversee industry-sponsored research, have substantial input into writing the final presentation of the results, and actually review the data from these joint ventures with industry, then academic-industry collaboration can be fruitful. However, if academics are simply used to recruit patients for clinical trials, stamp their names on papers consisting of data with which they are entirely unfamiliar, and are complicit in hiding negative data, then the current sad state of affairs will continue unabated.

Given the current financial situation, universities will be encouraging faculty very strongly to get external funding for their work, and we can only hope that academics will behave responsibly when such collaborations occur.

Sowing the Seeds of Lexapro

2009-01-07T10:11:00.000-08:00

I'm reading an article with my jaw completely agape and I thought I'd share the pain. The good people at Forest Pharmaceuticals have put together a tragic waste of journal space. The editorial board at the journal Depression and Anxiety should call an emergency meeting to see how this thing got published. Any peer reviewer who put a stamp of approval on this should be forced to listen to Michael Bolton's Greatest Hits at maximum volume for 12 hours straight.

OK, so what am I having a fit about? Here's what happened in this so-called study. 109 primary care doctors were recruited to participate, for which they were doubtlessly paid a decent chunk per patient (not discussed in the manuscript). The lucky depressed patients of these physicians then received escitalopram (Lexapro) for six months. The manuscript mentions that the "investigators" (the primary care docs) "were not required to have previous clinical research experience to be selected for this study." Yeah, no kidding.

There was no control group, and there had already been dozens of studies on the effects of Lexapro in depression, so how are we getting any new info out of this study? Maybe because this is investigating Lexapro in primary care settings; maybe there was no research on that beforehand. Well, no. The manuscript writes that "The efficacy and tolerability of escitalopram in MDD have been extensively evaluated in primary-care settings," citing four relevant studies. So the study is actually not an attempt to answer a scientific question. So what, exactly, is this study?

Looks and smells like a seeding trial, about which Harold Sox and Dummond Rennie wrote:

This practice—a seeding trial—is marketing in the guise of science. The apparent purpose is to test a hypothesis. The true purpose is to get physicians in the habit of prescribing a new drug. Why would a drug company go to the expense and bother of conducting a trial involving hundreds of practitioners— each recruiting a few patients—when a study based at a few large medical centers could accomplish the same scientific purposes much more efficiently? The main point of the seeding trial is not to get high-quality scientific information: It is to change the prescribing habits of large numbers of physicians. A secondary purpose is to transform physicians into advocates for the sponsor’s drug. The company flatters a physician by selecting him because he is “an opinion leader” and incorporates him in the research team with the title of “investigator.” Then, it pays him good money: a consulting fee to advise the company on the drug’s use and another fee for each patient he enrolls. The physician becomes invested in the drug’s future and praises its good features to patients and colleagues. Unwittingly, the physician joins the sponsor’s marketing team. Why do companies pursue this expensive tactic? Because it works.

So these primary care doctors now feel like "researchers," even though their investigation had essentially zero scientific merit. That probably makes these "investigators" feel important -- and the association between feeling important/scientific and Lexapro is a feeling Forest was banking on to increase Lexapro prescriptions in Canada.

Findings: So what did this extremely important piece of seeding, er, research find? Get ready... Lexapro is safe and effective. To quote the authors: "Escitalopram was well tolerated, safe, and efficacious. Escitalopram can be used with confidence to treat patients with MDD in Canadian primary-care settings." And "As adherence to antidepressant treatment is paramount to achieving long-term recovery, the present results suggest that escitalopram should be considered among the first-line choices of antidepressant used in primary care." So with no control group, we can determine that a Lexapro prescription should be among the first things that come to mind when treating depression. This is mind-boggling. This journal often published good work, but this is among the most uninformative pieces of research I have read. Unless one is thinking about marketing, in which case it is very enlightening.

We're All Mentally Disordered: College-Age Edition

2009-01-05T12:46:00.000-08:00

A study in the December 2008 issue of the Archives of General Psychiatry concluded that almost half of college aged Americans suffered from a DSM-IV disorder over a one-year timeframe. Yes, I am behind the curve on this one -- Furious Seasons was all over this last month (1, 2). Rather than rant about the very odd idea that half of young adults are suffering from a mental disorder, I want to start by mentioning one aspect of the study -- perhaps the most important one. Let's look at how the diagnoses were assigned. To quote from the study:

All of the diagnoses were made according to DSM-IV criteria using the National Institute on Alcohol Abuse and Alcoholism Alcohol Use Disorder and Associated Disabilities Interview Schedule–DSM-IV version, a valid and reliable fully structured diagnostic interview designed for use by professional interviewers who are not clinicians.

If the interviewers are not clinicians, on what basis are they trained to understand what makes for truly significant distress that might justify a mental health diagnosis versus someone who is suffering from more mild symptoms that do not comprise a mental disorder? Here's some information from a different study that used a different slice of the same overall dataset on which the December 2008 study was based:

Approximately 1800 lay interviewers from the US Bureau of theCensus administered the NESARC using laptop computer–assistedsoftware that included built-in skip, logic, and consistencychecks. On average, the interviewers had 5 years’ experienceworking on census and other health-related national surveys.The interviewers completed 10 days of training. This was standardizedthrough centralized training sessions under the direction ofNIAAA and census headquarters staff.

So the figures that will be trotted out in the media ad infinitum about the shoddy mental health of American youth are based on laptop-assisted interviews conducted by people who apparently have no formal training in mental health. Maybe mental health and related disability are really so easy to assess that we don't need experienced, formally trained interviewers. If that's the case, maybe we should just have Census Bureau interviewers provide initial mental health assessments in clinical care settings -- after all, if they are such good mental disorder detectors, couldn't we just train a bunch of interviewers rather than spend millions of dollars training and paying mental health professionals? Think of the savings!

I mean no disrespect toward the Census Bureau interviewers. They are performing important work that in many instances helps us to better understand the health of the nation. All I'm saying is that we might want to avoid uncritically accepting judgments of our nation's mental health based on interviewers who lack mental health training and experience.

KOL Continues to Vanish

2009-01-02T16:09:00.001-08:00

Charles Nemeroff, about whom I have written much, continues to disappear. His latest vanishing act: From a psychiatric research gathering in Berlin in late November 2008. Their website now reads: "Dr. Charles B. Nemeroff (Atlanta, the USA) called his participation off in the congress and its scientific contributions." We can only hope that they had another key opinion leader of his stature to replace him.

Back story.

The Incredible Vanishing Key Opinion Leader

2008-12-17T06:17:00.000-08:00

Charles Nemeroff, former chair of psychiatry at Emory University and key opinion leader extraordinaire has vanished. Not quite vanished from the face of the Earth, but from Medscape CME and now from a Georgia mental health commission. Nemeroff was found to have not disclosed a whole boatload of money he received from Big (and little) Pharma according to an investigation by Senator Charles Grassley. For example, it appears that Nemeroff received about $20,000 in cash from GlaxoSmithKline in one month in exchange for promoting GSK products to his peers.

I have previously written about a number of, um, "interesting" behaviors on the part of Nemeroff, which I recommend you read in order to understand that Nemeroff has, on several occasions, engaged in behavior that certainly appears to have placed the causes of his corporate sponsors over science. Not good for an "independent" researcher.

And now, it seems that Chuck Nemeroff is vanishing. Dr. Bernard Carroll noted that Nemeroff's continuing medical education offerings had vanished from Medscape and offered the following:

Well, good for Medscape. They came in for their share of criticism, here and here, a while back. Now they deserve credit for displaying ethical standards. Meanwhile, we are waiting for another company called CME Outfitters to get the message. Dr. Nemeroff is slated to moderate a raft of new programs for this company in the coming weeks, sponsored by corporations like Pfizer, AstraZeneca, and Ortho-McNeil Janssen. CME Outfitters' logo, after all, is Education with Integrity. Sooner or later the pharmaceutical corporations, like the CME companies, will understand that they are not helping themselves by trotting out a shopworn and sleazy KOL figurehead like Nemeroff for their marketing efforts. And other KOLs who up to now were willing to "wet their beaks" in these CME forums controlled by the Boss of Bosses Nemeroff will now be leery of associating with him.

Well, CME Outfitters is still rolling with Nemeroff. For example, he has an upcoming program called "Atypical Antipsychotics in Major Depressive Disorder: When Current Treatments Are Not Enough," which is a scary thought given that he appears to have been pulling data from thin air for a prior CME exercise in which he pimped risperidone as a treatment for refractory depression. Specifically, Nemeroff's presentation claimed that risperidone improved sexual function in a clinical trial, when the published article based on the trial's results said no such thing. In addition, Nemeroff's claim that risperidone had shown efficacy in a short-term study versus placebo for depression was also unsupported. So I'm thinking the upcoming program on antipsychotics for depression might be a fantastic example of marketing beating the crap out of science.

Georgia appointed a commission to address several issues within the public mental health system. They have completed a report. Interestingly...

The final version also does not contain the name of commission member Charles Nemeroff, an Emory psychiatry professor who has been a subject of a U.S. Senate Finance Committee investigation into whether drug company money paid to doctors and academics compromises medical research and scholarship. Nemeroff, an internationally known expert on depression, did not attend recent commission meetings.

But Nemeroff was appointed to the commission with some fanfare. The press release listing Nemeroff's accomplishments is pretty lengthy. The Georgia state legislator who appointed Dr. Nemeroff said, "I am confident that Charles will be an asset to this commission and will serve as a strong advocate for the people of Georgia being served [by] our mental health systems"

Yet Nemeroff was not on the final report. If it weren't for his work on CME Outfitters, I would be worried that we might need to file a missing persons report for Dr. Nemeroff.

Update (12-18-08): The Wall Street Journal Health Blog has two interesting posts on Dr. Nemeroff (1, 2). Read them and feel free to file them under "bizarre."
