The controversy over Xarelto approval by the FDA and alleged
irregularities in the conduct of the ROCKET-AF clinical trial continue
to hang over the heads of Bayer and Janssen (a division of Johnson &
Johnson), the manufacturers and marketers of Xarelto, in the national
MDL litigation. Since the inception of the Xarelto MDL proceedings
before Judge Fallon in New Orleans, the plaintiffs have contended that
there were irregularities in the ROCKET-AF clinical study, which served
as the basis for approval of the drug in the United States several years
ago. The plaintiffs contend that irregularities in the conduct of that
study underestimate the risks of serious
Xarelto bleeding events (GI bleed,
cardiac tamponade, intracranial hemorrhage, etc.) associated with
Xarelto while overstating the benefits of the drug in preventing strokes
when compared with warfarin (also known as Coumadin).
Over the past few months, there have been a number of motions filed in
the MDL federal court proceedings seeking to unseal a number of
documents that may help to shed light on this issue. In February of
2016, the New York Times wrote an investigative report on irregularities that may have occurred during the clinical study.
On March 16, 2016, the Editor in Chief of the British Medical Journal sent a letter to Judge Fallon
requesting that confidential information that has been uncovered during
the course of the litigation be released to the public “so that
appropriate review and scrutiny may take place. The documents at issue
here are not a trivial matter: they relate directly to ongoing
regulatory investigations and question the safety of a medicine that is
being taken by millions of patients around the world.” The BMJ Editor’s
request specifically noted the need for release of sealed documents that
relate to, among other things, “that the sponsor, Janssen, was aware of
a malfunctioning device during the ROCKET-AF trial” and “evidence of
possible misconduct during the peer review process of Duke Clinical
Research Institute’s reanalysis of ROCKET-AF data, which was published
in the New England Journal of Medicine.” On February 3, 2016, the British Medical Journal published an article entitled “Rivaroxaban: can we trust the evidence?” which shed light into the possible use of a faulty device during the ROCKET-AF trial.
On March 15, 2016, the Project on Government Oversight (“POGO”),
a nonprofit watchdog organization, also wrote to Judge Fallon seeking
release of the sealed Xarelto documents that are included in the MDL
discovery production. This group is particularly interested in the
details regarding the ROCKET-AF clinical trial, oversight of Xarelto by
the FDA and the European Medicines Agency, and the involvement of Dr.
Robert Califf (who is now the Commissioner of the FDA) in the clinical
trial that led to the FDA’s approval of Xarelto.
In its letter, POGO noted to Judge Fallon: “In the litigation before
you, plaintiffs and defendants have given sharply divergent accounts of
evidence that remains under seal, leaving all others to wonder which
account if either is accurate. The press and the public should be
permitted to see the evidence in this case and assess it for
themselves.” The letter to the judge closed by saying: “All too often,
class action lawsuits and the like raise important questions involving
the public interest and are then resolved on terms that forever bury the
answers. Please do not allow that to happen in this case. Please unseal
the evidence as complete and expeditiously as possible.”
The judge’s order does not directly address these requests other than
to make the letters part of the MDL record. Judge Fallon did, however,
enter orders relating to the Plaintiffs’ Motion to Challenge
Confidentiality Designations and directed that certain exhibits be
delivered to the Food & Drug Administration. Also, it appears that
there are a number of investigations ongoing by these watchdog
organizations, regulatory agencies, and medical journals with regard to
these troubling issues.
