|How Glaxo recruited 7-17 year old children for their Japanese Paxil study|
Back in 2009 I reported on how GlaxoSmithKline Japan were trialing out Paxil/Seroxat in children and adolescents. Over the following months I sought to find out why such a study was taking place, it seemed odd, to say the least, that GlaxoSmithKline were trying to prove their drug was safe in children and adolescents when it was blatantly obvious that it was not safe and effective.
The clinical trial, aimed at 7-17 year olds, went ahead, an 8 week trial which, it appears, was for the sole purpose of trying to prove one thing, at least that's the impression I get when reading the results.
What did Glaxo wish to push the boat out for? Well, my assumption, because I'm allowed to assume, is that Glaxo will use the results of this study to spin the suicidal ideation in kids claims that they hid in the earlier Paxil 329 study.
The 2009 study, which was completed earlier this year, shows a quite remarkable change.
You've guessed it folks.
Take a look at the following table:
You will note that the psychiatric disorders shows there were 3 reports on placebo whilst none were reported for Paxil. I't's hardly convincing seeing as there were only 29 subjects taking Paxil but I'm sure GlaxoSmithKline will use this to their advantage.
However, it would appear that the study proves nothing. Paxil was only slightly superior compared to placebo but it's all irrelevant anyhow.
Personally, I feel the only reason this study took place was to highlight the suicidal thoughts or lack of - Glaxo will no doubt spin this in future medical journals...or rather key opinion leaders handpicked by Glaxo will.
With just 29 subjects on Paxil they would have been lucky to pick up just one (3 per hundred is about 1 per 33). The low number of participants in the active treatment group pretty well ensured they most likely would not see emergent drug induced suicidality.
The study, like 329, has been manipulated, that's my opinion anyway, I'm still allowed an opinion aren't I?
If you look at the original exclusion criteria for this study you will see that it is not based on real-world prescribing. Remember just 1 subject in a hundred becoming suicidal because of the drug equates to 1000 subjects per million. And nobody knows for certain how many of those will go on to kill themselves - we do know that there have been many.
Each subject in this trial were asked a series of questions to determine if they were experiencing adverse reactions, the questions were, it appears, based on the CDRS-R rating scale
The CDRS-R is a brief rating scale based on a semi-structured interview with the child (or an adult informant who knows the child well). Designed for 6- to 12-year olds, and successfully used with adolescents, it can be administered in just 15 to 20 minutes and easily scored in a few minutes more. The interviewer rates 17 symptom areas (including those that serve as DSM-IV criteria for a diagnosis of depression): [SOURCE]
Difficulty Having Fun
Depressed Facial Affect
Most of these symptom areas are rated on a 7-point scale so the CDRS-R can capture slight but notable changes in a child's symptoms. This makes the scale ideal for monitoring symptoms during illness or remission. Other additions to the scale include suggested interview prompts and guidelines for integrating information from multiple informants.
Japanese Medwatch were concerned about this particular study, so concerned that they wrote the following to GSK Japan:

The results of the trial have now been published online and can be viewed HERE
I anticipate they will appear [polished and spun] in medical journals soon.
