Drug research, even from clinical trials sponsored by the federal government, is routinely suppressed, according to a new study in the British Medical Journal (BMJ), an international peer-reviewed medical publication. The study found that less than half of all NIH-funded clinical drug trials were published in a medical journal within two and a half years of the trial’s completion—with fully one-third of trial results remaining unpublished even four years after the trial. Why? Because the drug manufacturers didn’t like the data.
One example cited in the study was the FDA-approved diabetes drug Avandia, which in 2007 was found to increase heart attacks and cardiovascular deaths—even though the drug’s maker, GlaxoSmithKline, had known about the risk before the drug was approved. The BMJ study found that 35 of the drug’s 42 clinical studies had never been published, and were obtained only because a court case required the pharmaceutical company to turn over the data.
