The New England Journal of Medicine has revealed in an editorial that Vioxx manufacturer Merck & Co. concealed heart attacks suffered by three patients during a clinical study of the painkiller published in the NEJM in 2000.
The editorial, written by the journal's editor in chief, executive editor, and a third doctor, also alleges that Merck deleted other relevant data before submitting their article for publication.
The study in question has been a key part of testimony in the product liability trials over the drug.
The journals editors said they discovered the apparent deletions as part of preparations for a deposition in connection with the Vioxx lawsuits. When they reviewed the study, they found that the printed copy of the study and the version submitted on a disk didn't match: The negative cardiovascular data had been deleted from the paper copy the Journal used.
Merck faces roughly 7,000 lawsuits over Vioxx.
