Antidepressant Makers Withhold Data on failed drug trails

As seen in this story in the Washington Post

Makers of popular antidepressants such as Paxil, Zoloft and Effexor have refused to disclose the details of most clinical trials involving depressed children, denying doctors and parents crucial evidence as they weigh fresh fears that such medicines may cause some children to become suicidal.

The companies say the studies are trade secrets. Researchers familiar with the unpublished data said the majority of secret trials show that children taking the medicines did not get any better than children taking dummy pills.

Although the drug industry's practice of suppressing data unfavorable to its products is legal, doctors and advocates say such secrecy distorts the scientific record.

"Conflicts of interest and the company control of the data have thrown out the scientific method," said Vera Hassner Sharav, a critic of the drugs and a patients' rights advocate. "If hundreds of trials don't work out, they don't publish them, they don't talk about them."
