A NEJM editor found out that additional data linking Vioxx to cardiovascular risk was deleted from a major study (VIGOR) published five years ago. Merck researchers deleted the data 2 days before submitting the paper manuscript.The authors underreported the number of heart attacks suffered by Vioxx patients, claiming that there were 17 heart attacks when there were actually 20.
The additional events were disclosed to the FDA in 2000.
NEJM Editor-in-chief Jeffery Drazen says: "There's a difference between the letter of the law and the spirit of the law, and what Merck did conformed with the letter of the law. But in my opinion, it broke the spirit of the law because you're using human subjects, participants in this trial, and you're putting them at risk".
On Dec 8, NEJM released an editorial entitled "Expression of Concern" which asks the VIGOR authors to submit a correction of the manuscript.
"Is this Watergate for Merck?", asks Kevin, M.D.
