Pfizer’s manipulation of Neurontin studies – we’ve got the documents right here
A major story broke today in the New York Times, Wall Street Journal and Boston Globeabout Pfizer’s (NYSE:PFE) alleged manipulation of studies of its epilepsy drug Neurontin:

The studies examined whether Neurontin was effective for conditions other than epilepsy. As the NY Times article describes,
Pfizer’s tactics included delaying the publication of studies that had found no evidence the drug worked for some other disorders, “spinning” negative data to place it in a more positive light, and bundling negative findings with positive studies to neutralize the results, according to written reports by the experts, who analyzed the documents at the request of the plaintiffs’ lawyers.
Neurontin has been an extraordinarily profitable drug for Pfizer, and most of the prescriptions written for it were not for epilepsy, but were “off-label” (prescribed for a use not approved by the FDA). In 2004, Pfizer paid $430 million to settle a criminal and civil case brought by federal prosecutors that charged that Warner-Lambert, which Pfizer acquired in 2000, had illegally promoted Neurontin for “off label” purposes in the 90s.
That $430 million settlement reimbursed state and federal health care programs (like Medicaid) that had paid for off-label prescriptions of Neurontin, but did not compensate consumers or “third party payors” (health plans, union benefit funds and others) that had also paid for such prescriptions. A number of class action lawsuits were brought against Pfizer, and they were consolidated in the U.S. District Court for the District of Massachusetts. The ongoing lawsuit is In re Neurontin Marketing and Sales Practices Litigation, MDL #1629, Docket #04-10981.
That case has been pending for several years, with the parties exchanging documents and arguing before the Court about whether a national class of consumers and third party payors can be “certified,” which is the prerequisite to the case going forward as a class action.
The documents that were recently released were part of “expert reports” submitted by the lawyers for the plaintiffs in the case. The reports both contain and analyze documents from Pfizer about its alleged illegal offlabel promotion of Neurontin.
Now that the reports and documents have been filed with the Court, they are a matter of public record. We here at Prescription Access Litigation subscribe to the maxim that “sunlight is the best disinfectant.” We are posting these reports and documents in their entirety so that the public can see them for themselves. They paint an interesting picture.
