5. Zoloft had an overall higher response rate than placebo (48.6 % Zoloft vs 43.1 % Placebo).
Yeah, on "second measures". Though I don't know if we're talking abbout the same study.
http://www.eurekalert.org/pub_releases/2002-04/du-sjw040402.php
Davidson said something stupid. He said that taking SJW was like playing russian Roulette with your health. Though, this study suggests that taking zoloft is more of a risk.
He also said. "It is very important to treat it early and effectively,". But the study doesn't offer any concrete answers on how one should go about doing that.
The problem is that news stations only broadcasted that "SJW is no more effective than placebo", instead of saying that "SJW and Zoloft are no more effective than placebo"

The placebo dose could have been increased, that can work too!Personally I am not interested in the SJW aspect of the study (since I've never much subscribed to alternative modalities). Rather, I am concerned over the apparent sub-placebo efficacy of Zoloft. The fact remains - and there is no way to maneuver around this - that the dose of Zoloft used was relatively low.

> In some ways that is a perpetuated myth that people base a lot of assumptions on. It essentially is not true. The only real way to get an accurate idea of serotonergic functioning is post mortem. Those with suicidal "ideation" are not yet dead. In addition, no consistant findings regarding typtophan depletion tests, tryptophan hydroxylase genes, or serotonin transporter genes have ever been made in suicidal patients. Altered serotonergic binding has been noted, but that is not necessarily due to "low serotoniergic function". Some have suggested too that "low serotonin" is really just a marker of impulsivity, rather than depression at all. Then there is the recent discovery that serotonergic drugs can often make people suicidal. It all throws a kink in the theories.
>I read somewhere - though I cannot back this up with any references - that biopsies of the brains of suicide victims tend to show low serotonin levels.
Anyway, this particular study was skewed in favour of nonsuicidal patients, and as SLS points out in his cogent analysis of placebo efficacy, had those patients been included, the results of the Zoloft arm may well have been different.

>Placebo should be mandatory when testing absolute efficacy of a drug, I agree. But as others have pointed out already, the STAR*D study was designed to *compare* algorithm success rates, not to test whether the drugs actually work. Besides, from the "real-world" setting of the study, placebo would have been impractical. The study was conducted on patients actively seeking treatment rather than patients consenting to participate in research.

You guys are speculating. I think you are both wrong. I think the degree of placebo response is dependent on the selection criteria. I have already cited a paper regarding this issue.
> In addition, there aren't too many studies that follow these individuals to see if their treatments actually continue to work down the road.How long do you think they should be followed for? Is the STAR*D design sufficient?
This is usually the ultimate test. Its easy to get a response with all the bells a whistles, but when the support leaves, and all you've got is a drug, relapse rates are high.
Is this speculation? What are the statistics?
Certainly psychotherapy will enhance one's chances of getting well and remaining well. There are numbers on this. However, I have not seen the numbers on relapse rates once supportive psychotherapy is withdrawn. Let's see them.
> I relapsed within 2 weeks of leaving the hospital on a high dose of zoloft.
That would be considered a placebo effect if you began to "respond" during the first two weeks according to some researchers. You might not really have been responding to the drug. Placebo responders do not remain in remission for very long compared to true responders. You can look at the work of Frederick Quitkin regarding this.
> I wasn't quite sure if I got better because of the zoloft, or the fact that the hospital cafeteria served really good bacon.
It was likely neither.
> It is easy enough to ramp people up to a high dose of antidepressants to get some initial responses, but with the growing information bank regarding AD poop out we could add to the statistics.What exactly is that bank? Where can we find these statistics?
> I read some statistic stating that ~30% of AD responces end up pooping. So maybe only 35% of people actually get any long term benifit.
Cite it. Let us see if they separate out placebo responders first. If they don't, the statistics are worthless.

>
> Why should this be so? Most clinical studies seem to show similar or worse statistics. I don't know of too many trials that show better statistics.I believe I've already addressed this issue in previous posts. I have seen other abstracts on Medline and elsewhere reporting that clinical trials of antidepressants using rigid criteria allowing only the more severe cases of MDD demonstrate lower placebo response rates and greater superiority for putative antidepressants.
The following paper describes the failure of trials with high placebo response rates to demonstrate superiority of antidepressants, but not those with low placebo response rates. It is my contention that high placebo response rates are indicative of poorly designed inclusion criteria that allow people who do not have true MDD to enter the studies. I feel that this is more of a problem today than it was 20 years ago. I believe this is due to the increase in monetary pressure to produce subjects for clinical trials. This is born out by the steadily increasing rate of placebo response observed in these studies over the years. It is indeed ironic that the drug companies, in their haste and zeal, have cost themselves dearly in time and money by applying this pressure.

Just one more from Google:
Severity of Depression and Response to Antidepressants and Placebo: An Analysis of the Food and Drug Administration Database.Articles
Journal of Clinical Psychopharmacology. 22(1):40-45, February 2002.
Khan, Arif MD *+; Leventhal, Robyn M. BA *; Khan, Shirin R. *; Brown, Walter A. MD ++Abstract:
Some studies suggest that more severely ill patients with depression respond well to antidepressants and poorly to placebo, whereas those who are mildly ill respond equally well to antidepressants and placebo. This notion has implications for the design of clinical trials. To further assess and substantiate these putative predictors of antidepressant and placebo response, we assessed the Food and Drug Administration database of 45 phase II and III antidepressant clinical trials. The frequency of statistically significant differences between antidepressants and placebo was higher in the trials that included patients with more severe depression. In the antidepressant-treated groups, the magnitude of symptom reduction was signif-icantly related to mean initial Hamilton Rating Scale for Depression (HAM-D) score; the higher the mean initial HAM-D score, the larger the change. With placebo treatment, however, the higher the mean initial HAM-D score, the smaller the change. Early discontinuation was more frequent among patients whose mean initial HAM-D scores were higher. These data may help inform the design of future antidepressant clinical trials.

Nobody was stopping them from using higher doses. Higher doses do not always equate to higher efficacy.

May have. Its easy in hindsight to speculate, but designing a clinical trial to show these drugs are significantly better than placebo is hard.

It was my understanding, (I will look for a reference), that the areas in which zoloft performed better than placebo, were selected after the study was done. Ie, we set out to show it was better on these measures, which it wasn't, so we will select the areas which it did perform better on, and pertend as if those measures are the ones that matter.

Everybody here has been speculating. You sited a paper that *suggests* this *could* be a reason why placebo responces is high. To proove that this is true is much harder.
>How long do you think they should be followed >for? Is the STAR*D design sufficient?I'd say that a drug needs to work for a full year to be considered effective, but hey, thats just me.

Thats a good question. It is my understanding that depression has a high relapse rate.

I'd have to look. I guess my best counterargument at this point would be the lack of data showing that antdiepressants work long term.

People can relapse too if psychosocial stressors rise above the power of the AD. Perhaps this was the case with me leaving the hospital, and return to a high level of psychosocial stress.
>It was likely neither.
My money is on the bacon.
> It is easy enough to ramp people up to a high dose of antidepressants to get some initial responses, but with the growing information bank regarding AD poop out we could add to the statistics.
>What exactly is that bank? Where can we find >these statistics?
The bank I am referring to, is the increase in awareness that antidepressants can loose their effectiveness over time. Simply typing in "antidepressnant + poop out" in a search engine will return dozens of results. Doctors have been forced to confront the issue, such as in the article below, but I don't know if studies have been conducted. Poop out is a well known phenomina.
>Cite it. Let us see if they separate out placebo >responders first. If they don't, the statistics >are worthless.
Good point! I would imagine that studies about the issue would be in the works. The problem with things such as this is funding. Drug companies in general, do not want to pay for a study to determine the poop out rate of their drug. In addition, they have no requirement to proove that their drug works long term.

Clearly

When you're faced with the fact that overall the antidepressant effect vs. placebo is weak, it becomes natural to want to try and come up with reasons why.

Show me data to suggest that increased sevarity of depression has a higher ratio of active treatment to placebo response.

That study does support your claim, but it is numberless, and difficult to quantify the exact magnitude of discussed claim.
It may be clear that severe depression responds more poorly to placebo but it would be nice to know exactly how significantly the ratio of placebo to active drug changes with increasing sevarity of depression.
I am looking for more studies on this topic.

"the placebo response overall appears to have increased over time"
Curr Top Med Chem. 2005;5(11):1077-86.Is there a placebo problem in antidepressant trials?
Yang H, Cusin C, Fava M.
Depression Clinical and Research Program, Massachusetts General Hospital, Harvard Medical School, Boston, MA, USA.
In psychiatry, particularly in antidepressant clinical studies, placebo-controlled trials often yield results that are very difficult to interpret because of robust placebo responses. Meta-analyses of trials in major depressive disorder (MDD) suggest that drug-placebo differences in response rates range from 11% to 18%. However, in trials of marketed antidepressants present in the FDA databases, antidepressant drugs were superior to placebo in only 45 out of 93 RCTs (48%), and the placebo response overall appears to have increased over time. This gradual increase in placebo response rates may lead to delays in bringing new antidepressant treatments to the market, increased costs of antidepressant drug development and, in some cases, decisions to stop the development of certain compounds, or FDA decisions to not approve new treatments. A number of possible contributing factors to this significant placebo response in MDD have been identified, but further studies are needed. Many of the remedies used by researchers to minimize the placebo response, such as lead-in periods or shortening the duration of study visits, have failed to show consistent benefits. From our analysis of published studies, it appears that expectations about the speed of response may be shaped by the duration of the trial and that most of the placebo response occurs in the first half of the trial, regardless of its duration. These observations have led us to develop a novel approach to the placebo response problem called the Sequential Parallel Comparison Design.

"and the placebo response overall appears to have increased over time"
Perhaps, but what magnitide are we talking about. There are no numbers. It could have increased an average of 2% for all I know.
In one sense I can see drug responces in the past as being stronger since the TCA's are more effective drugs.
I would need some numbers that show how the placebo response has increased significantly.
Placebo response could have been lower in the past too due the the weaker "establishement" of AD's in the past.

The numbers are all there. All you have to do is go to the library and pull out the journals. I started doing that in 1982. That's how I knew the numbers had changed even before I encountered the literature I cited along this thread. I witnessed the changes in placebo response over a 25 year period. It has been far more than 2 percent.Currently marketed antidepressants work significantly better than our most recent clinical trials indicate.

I know this is going to come as terrible news to you, but there are still doctors who believe that 85% of sufferers of MDD can reach full remission by cleverly using all of the treatments currently available.
