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 Times reporter that the FDA finally announced the diabetes drug was being withdrawn from the U.S. market.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.

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.

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.

Rezulin Recall

The Rezulin recall took place on March 21, 2000, nearly two years after Public Citizen consumer group petitioned the FDA for the immediate removal of the diabetes drug and after two million people used the drug. Public Citizen petitioned for the Rezulin recall in July 1998 after reports of liver damage. When the FDA finally announced the Rezulin recall, there were 90 cases of liver failure reported from diabetes patients taking the drug, including 63 deaths.
