Lambasting the Times for a Naive Front Page Article
Here is a letter I wrote to Gardiner Harris in response to a disappointing article that appeared on the front page of the New York Times:
I was not able to respond to your article on the effectiveness of antidepressants in adolescents in a timely manner because I was attending my surviving daughter’s graduation at Princeton. I also wanted to do further research on the Emslie-March study, which I have now completed.
The exuberant tone of your article surprised me given the caution you have demonstrated in previous coverage of this issue. Why do you say “Antidepressants seen as effective” in your headline when only one – Prozac -- is being studied in the trial? You label the study a “landmark” event in the debate and state that Prozac is “far” better than talk therapy. How carefully did you really examine the design and the premature conclusions of this study before rushing to judgment and putting this on the front page of the paper? Why do you use the past tense when you say the study “was” the first to compare psychotherapy and drug treatment? It is still going on and will not be finished until 2006. There is a long way to go before asserting that Prozac is better than Cognitive Behavioral Therapy (CBT). Only the short term comparison has been completed and it is quite possible that the 12 week window is exactly the point at which antidepressant treatment may be at its most beneficial after the short term adverse effects are over and before the long term ones set in; it also may be too soon to measure the full benefit of CBT. Let’s remember that another study was published recently which showed that relapse in the year following treatment is higher in those on antidepressant medication than it is in those who had talk therapy.
Yes, the study is government rather than industry financed but that still does not mean it is being conducted objectively. Graham Emslie and John March both have extensive ties to the pharmaceutical industry as consultants. Graham Emslie, in particular, was responsible for the principle trial that purported to demonstrate Prozac’s effectiveness in adolescents and thus allowed it to be approved for use in children by the FDA. His reputation might be at stake if effectiveness is disproved now, hardly making him an independent researcher in this new study. His initial trial took place in 1997, involving 96 patients, half of which were on placebo and half on Prozac, and only lasted 8 weeks. 36 (37.5%) patients dropped out before the study was completed – 19 (39.6%) of those on placebo and 7 (14.6%) on Prozac. Except for one patient complaining of side effects, all those on placebo dropped out because of “non response”; on Prozac, however, only 3 dropped out for non response. 3 others (6.3% of the total on Prozac) dropped out because of the onset of manic symptoms and 1 for a severe rash. Despite this alarming development (3 out of 48 becoming manic) the drug was still approved for use in adolescents because of its reputed effectiveness in the rest of the group, yet at the conclusion of the study only 15 of the original 48 on Prozac actually had “minimal” symptoms of depression compared to 11 of the placebo group. The rest felt better but still met the criteria for a diagnosis of major depression. (Archives of General Psychiatry. 1997;54:1031-1037). This is the trial that allowed Prozac to go on to be prescribed “legitimately” to millions of children. Would you let your child take Prozac after understanding the details of how the numbers are used so selectively? The approval process depends on percentages, but the specific line data seems to tell a different story than the authors have really portrayed. Sadly, this is often the case in clinical trial reporting.
You do acknowledge that even if overall benefit is demonstrated there still may be a subgroup that is vulnerable and this is a step forward. Acknowledgement of a group that gets worse is long overdue. The question of how much worse needs to be addressed. Why is it not a shocking revelation that 5 adolescents attempted suicide on Prozac and only 1 on placebo? (And yet every effort was made to exclude anyone with a previous history of suicidality from participation.) At least you report this finding but seem to brush over it as nothing particularly important. You even quote John March as saying “The take-home message is that these adverse events are extremely rare.” Probably less than 200 adolescents were taking Prozac. At least 2.5% of those tried to commit suicide. I don’t call this “extremely rare” given the seriousness of what we’re talking about. Why did 61 out of 439 (that’s 1 out of 7 or 13%) drop out? How many of those dropped out because of adverse reactions to Prozac and exactly what were the adverse reactions? Exactly what does “non response” to Prozac consist of? And in practice these drugs are consistently being given to patients with a history of suicidality. What would happen to the number of suicide attempts if such patients were included in the trial?
As a reporter covering this important issue I wish you were asking these critical questions. Many medical professionals are bemoaning the controversy surrounding antidepressants and reiterating the threat of suicide in untreated depression. As a “suicide survivor” I want to remind everyone that the risk of suicide in antidepressant treated depression may actually be higher than in untreated depression. No one knows for sure. It is shameful that statistics comparing the number of suicides in treated and untreated patients are not readily available, but at the moment no one is tracking the number of completed suicides which occur in those on antidepressants or investigating them in detail.
It was fortuitous that Eliot Spitzer filed his suit on the very day you reported the preliminary Prozac trial results announced in Phoenix. It provided a much needed antidote to your exuberance. I hope that the next time there is a laudatory announcement about antidepressants you will approach it with the critical eye it deserves.

ANTIDEPRESSANTS SEEN AS EFFECTIVE FOR ADOLESCENTS
By GARDINER HARRIS
In the midst of a worldwide debate on whether depressed children should be treated with antidepressant drugs like Prozac, a landmark government-financed study has found that Prozac helps teenagers overcome depression far better than talk therapy. But a combination of the two treatments, the study found, produced the best result.
The study, sponsored by the National Institute of Mental Health, was the first to compare psychotherapy and drug treatment for depressed adolescents. Statistically, the researchers found, talk therapy -- in which a patient discusses problems with a therapist -- was by itself no more effective in reducing the depression than treatment with placebos. But when combined with drug treatment, psychotherapy appeared to provide added benefit and to reduce the risk of suicide.
The findings are likely to reassure psychiatrists, pediatricians and others who increasingly prescribe antidepressants to teenagers and children. Millions of young people take the drugs.
Experts said that the study was notable for its size and for the fact that it was carried out without financing by drug manufacturers. Data on the effects of antidepressants in adolescents is in short supply. Most studies of the question have been small trials sponsored by pharmaceutical companies and have failed to show that the drugs are effective for depressed teenagers.
''This study should put to rest doubts about whether these drugs work in teenagers with severe depression,'' said Dr. Graham Emslie, a professor of psychiatry at the University of Texas Southwestern Medical Center and an author of the study, which was presented here on Tuesday at a meeting of psychiatric drug researchers.
Still, the findings are unlikely to resolve the controversy over whether Prozac and similar drugs lead a small number of teenagers and children to become suicidal.
Such concerns led the Food and Drug Administration to warn earlier this year that patients taking the drugs should be watched closely for signs of suicide or other harmful behavior in the first weeks of therapy. The agency is reanalyzing suicidal events that occurred during drug-company trials of antidepressants in children and teenagers. British drug regulators have banned the use of all but Prozac in those younger than 18.
The government study, called the Treatment for Adolescents with Depression Study, involved 439 youths ages 12 to 17 who were suffering from moderate to severe depression.
The adolescents were randomly assigned to be treated for a period of 36 weeks with either Prozac, the antidepressant drug made by Eli Lilly & Company; a form of talk therapy known as cognitive behavioral therapy; placebo pills; or a combination of Prozac and talk therapy.
The researchers collected data on the subjects for a year, but have only analyzed information from the first 12 weeks so far. Of the youths recruited for the study, 378 completed the first 12 weeks of treatment. Their mean age was 15. Depression levels were measured using several common psychological scales.
Using one measurement scale, the researchers found that after 12 weeks, 71 percent of the subjects who received Prozac and talk therapy responded well to treatment, compared with 61 percent of those who received Prozac alone, 43 percent of who received talk therapy alone and 35 percent of those who received a placebo treatment. By another measure, talk therapy alone fared no better than treatment with placebos.
The researchers also found that patients became significantly less suicidal, no matter which treatment they were given. No patient committed suicide during the trial. But the risk of a suicide attempt among the patients given Prozac was twice that of those who were not, the study found. There were five suicide attempts among those given Prozac and just one among other patients.
Dr. John March, a professor of psychiatry at Duke University and the study's lead investigator, said that the findings showed Prozac's benefits for depressed teenagers and children far outweighed its risks. ''The take-home message is that these adverse events are extremely rare,'' Dr. March said.
He acknowledged, however, that the controversy about suicide and antidepressant therapy was far from resolved. ''We're all holding our breath to see what the F.D.A. is going to do,'' Dr. March said.
Psychologists, who are often the providers of talk therapy and who cannot prescribe drugs, are likely to be disappointed in the finding that cognitive behavioral therapy was found to be little better than a sugar pill. A recent major trial comparing drugs with talk therapy in children with attention-deficit disorder also showed that the drugs worked better.
But the findings of another study presented on Tuesday suggest that for some conditions, talk therapy may be more effective than antidepressants. That study compared cognitive behavioral therapy with Zoloft, an antidepressant made by Pfizer that is similar to Prozac, in teenagers who suffered from obsessive compulsive disorder. Those who received the talk therapy, the study found, improved more than those who were treated with the drug.
Dr. Thomas Insel, director of the National Institute of Mental Health, said he was pleased the results of the depression study were so clear. The institute spent $17 million over six years financing the trial. ''The most striking thing about the study is that, in all groups, there was a dramatic decrease in the amount of suicidal thinking,'' he said, suggesting that all the therapies were protective.
Dr. David Brent, a professor of psychiatry at the University of Pittsburgh not involved with the study, suggested that another form of talk therapy called interpersonal therapy might have fared better than cognitive behavioral therapy.
In interpersonal therapy, clinicians focus on a patient's relationships with peers and family members and the way they see themselves. In cognitive behavioral therapy, clinicians teach patients to try to think more positively and do things that make them happy.
Dr. Brent said it was good news that drugs produced better results than talk therapy ''because it's hard to get people into cognitive therapy anymore. They just don't want to take the time.''
The researchers said they planned to publish the preliminary results of the study this summer, with further analyses later.
Dr. Insel said that the most useful information from the study is yet to come. ''We need to know which treatments work best for what kinds of kids and who may be the most vulnerable to the side effects,'' he said. Those sorts of answers would come from more data analysis, he said.
''We're going to get a lot out of this study that the public really needs to know right now,'' Dr. Insel said.
