Rezulin Recall
Rezulin Recall History
The L.A. Times was very involved with the Rezulin
recall. It was not until after a whistleblower showed internal
FDA email messages to an LA. Times reporter that the FDA
finally announced the diabetes drug was being withdrawn from the
U.S. market. Following this announcement, the L.A. Times
reported on the history of the Rezulin recall, outlining notable
events from the development of Rezulin until the recall. These are
the events that The Times published.
If you have taken Rezulin and would like more information regarding
the Rezulin recall, contact us
to speak with a Rezulin attorney. You may be entitled to a large
compensation for the damages and suffering that have resulted from
taking the diabetes drug.
June 11, 1996
The National Institutes of Health chooses Rezulin to use in a $150
million diabetes study, run by Richard Eastman, the government's
top diabetes doctor. Eastman was hired by Rezulin manufacturer Warner-Lambert
as a consultant to launch Rezulin. After the study Warner-Lambert
issues a press release saying that Eastman found Rezulin to correct
underlying causes of diabetes.
July 31, 1996
Rezulin manufacturer applies for the FDA approval of the diabetes
drug under the "fast-track" procedures, which had pretty
recently been enacted.
October 9, 1996
FDA scientists become concerned with Rezulin's potential for liver
damage and heart in animal studies. The first FDA doctor to look
at Rezulin was Dr. John Gueriguian who was opposed to the drug's
approval.
November 4, 1996
Warner-Lambert has Dr. Gueriguian removed from the Rezulin evaluation
after the manufacturer complains about his intemperate language.
His removal also dismisses his Rezulin review from the FDA files.

December 11, 1996
Rezulin is presented by Warner-Lambert to an FDA advisory committee
in order to get approval and states that their diabetes drug does
not increase cardiac mass or impair cardiac function.
January 1997
Rezulin received FDA approval through the "fast track"
approval procedure that cut the time it took to be approved in half
the normal time. There is no liver testing required.
February 24, 1997
The FDA states that Warner-Lambert made "false and misleading"
claims about Rezulin in a press release, recommending the news release
be immediately discontinued, as well as any other piece of information
containing similar claims.
May 1, 1997
Warner-Lambert's clinical studies indicated that Rezulin users were
3.6 times more likely to suffer liver injury than patients taking
placebos, but the company runs a full-page, color magazine ad describing
Rezulin as having side effect comparable to placebo.
May 5, 1997
The CEO of Warner-Lambert tells investors that Rezulin holds the
potential to be a billion dollar blockbuster.
September 30, 1997
The FDA Diabetes Group Leader, Dr. Alexander Fleming, finds it "hard
to believe that patients with cardiac, liver, or renal disease would
not be adversely affected by the drug."

October 10, 1997
The FDA receives two reports of Rezulin liver failure.
November 3, 1997
The
FDA requires the Rezulin label be changed to recommend liver
enzyme tests within the first one to two months and then every three
months during the first year of Rezulin therapy and then periodically
after that. Symptoms of Rezulin liver
dysfunction including, nausea, vomiting, abdominal pain, fatigue,
loss of appetite,
or dark urine should get liver function tests performed. Any Rezulin
patient who develops a liver injury should immediately discontinue
the use of the drug. Clinical trials showed approximately 2% of
Rezulin patients should be expected to stop taking the drug due
to an elevated level of liver enzymes.
November 12, 1997
Dr. Robert I. Misbin, an FDA diabetes specialist that supported
the Rezulin approval, sent an internal report to FDA supervisors
stating that 21 patients treated with Rezulin prior to FDA approval
had to discontinue the drug due to Rezulin liver injury, 13 patients
had markers of Rezulin liver injury 10 to 30 times above normal
which can threaten the lives of patients, and an estimated 2% or
12,350 of the 650,000 patients using Rezulin would experience some
degree of liver injury.

December 1, 1997
England prohibits sales of Rezulin due to concerns about liver damage
to patients in the U.S. The FDA
announces a label change to require more frequent Rezulin liver
testing. The new label recommends liver enzyme tests before starting
Rezulin, monthly for the first six months of treatment, every other
month for the next six months, and periodically thereafter.
May 17, 1998
A 55 tear old woman in good health dies of Rezulin
liver failure while participating in the National Institutes
of Health diabetes study. The panel of specialists hired by NIH
concluded that her liver failure was probably due to the use of
Rezulin diabetes drug.
June 4, 1998
The NIH study drops Rezulin due to the risk of liver damage in the
remaining participants.
June 5, 1998
A press release by Warner-Lambert denies Rezulin killed the woman
and instead claimed her death was the result of complications unrelated
to the study or the diabetes medication. The FDA had then received
21 reports of Rezulin liver failures resulting in death and three
Rezulin liver transplant patients.
July 27, 1998
The consumer group Public Citizen filed a petition for the immediate
ban of Rezulin. At this point the FDA had received 26 reports of
Rezulin liver failure deaths.
top
July 28, 1998
The FDA
required another Rezulin label change to increase the frequency
of liver testing. The recommendation then stated a Rezulin patient
be tested before using Rezulin, monthly for the following 8 months
and every two months for the rest of the year and periodically after
that.
January 1999
The FDA Commissioner orders a reevaluation of Rezulin after the
series of articles by the Los Angeles Times investigated the "fast
track" drug Rezulin tied to 33 Rezulin liver failure deaths.
March 26, 1999
After two months of FDA research the findings are present to an
FDA advisory panel. The report found that an estimated 430 or more
Rezulin patients have suffered a liver failure, Rezulin patients
incur 1,200 times more risk of liver failure, one out of every 1,800
Rezulin patients can expect t suffer a liver failure, and liver
function tests do not provide enough protection due to the rapid
and unpredictable way Rezulin can affect the liver. In addition,
Rezulin patients did not follow the recommended liver function tests
after more than 4 months on the drug.

March 29, 1999
A Rezulin patient undergoing monthly monitoring in a Warner-Lambert
clinical trial dies of liver failure.
June 16, 1999
The FDA
requires the Rezulin label be changed for the fourth time now,
increasing the frequency once again for liver tests. The new label
recommended Rezulin patients get monthly liver monitoring for the
first year on the diabetes drug.
December 15, 1999
The Los Angeles Times reports 21 Rezulin patients have died of liver
failure since the March 26, 1999 report by Dr. Graham to the FDA
Advisory Panel. Graham begins a new analysis of Rezulin despite
his supervisors having no knowledge of his actions.
March 3, 2000
Dr. Graham sends an email to 14 FDA officials with the opinion that
Rezulin is unsafe and should be stopped due to the liver failure
problems occurring. Graham stated there was no existing data to
support the idea that monitoring can prevent the Rezulin liver failures
from occurring.

March 2000
The
FDA diabetes specialist who had analyzed the first cases of liver
failure in October to November 1997 sends eight members of Congress
internal FDA emails discussing Rezulin liver toxicity. Included
in the email was the correspondence he had received from Dr. Janet
B. McGill who had conducted early research on Rezulin for Warner-Lambert
saying the company "deliberately omitted reports of liver toxicity
and misrepresented serious adverse events experienced by Rezulin
patients in their clinical studies." The FDA opens an internal-affairs
investigation after Warner-Lambert complains about the leaks.
March 21, 2000
The FDA
withdraws Rezulin from the U.S. market after finding the benefits
of other diabetes drugs offer the same benefits Rezulin did without
the same risks. Up to this point Warner-Lambert had grossed $2.1
billion in Rezulin sales. The FDA had reports of 63 Rezulin liver
failure deaths.
August 16, 2000
The L.A. Times reports about the Federal prosecutors examining the
FDA's quick approval method and the delayed withdrawal of Rezulin.
It was reported that both the FDA and Warner-Lambert's actions were
being examined.
