Documents on Seroquel show drugmaker knew of risks

Internal AstraZeneca reports and e-mails written by company officials show they knew a decade ago that their psychiatric drug Seroquel caused diabetes and major weight gain, plaintiffs’ lawyers said Friday after releasing dozens of the previously sealed documents.

“They not only failed to warn about the risk of diabetes, but they marketed it as not having that risk,” said Houston attorney Ed Blizzard, one of the lead attorneys representing roughly 15,000 plaintiffs suing the British drugmaker.

The plaintiffs claim Seroquel, approved for treating schizophrenia and bipolar disorder, caused diabetes, weight gain and related health problems, from kidney failure and heart attacks to amputations and damage to the pancreas, which makes insulin.

AstraZeneca spokesman Tony Jewell said plaintiffs’ lawyers are “mischaracterizing that we knew that it caused diabetes.” He said it remains unresolved whether Seroquel causes diabetes, and that AstraZeneca PLC has shared all relevant and required data with the Food and Drug Administration, both before and after the FDA approved Seroquel as safe and effective in 1997.

“AstraZeneca believes that the Seroquel (detailed package insert) has always provided adequate and appropriate information and warnings based on available data,” Jewell said.

Blizzard claims that the company knew as early as 1997 that Seroquel caused significant weight gain – a problem linked to the surge in new cases of Type 2 diabetes – and knew by 2000 that it caused diabetes in some patients.

“Our position was that the public has the right to know” what the documents contain, Blizzard told reporters during a Friday afternoon teleconference.

Among the hundreds of pages released Friday were a 1997 e-mail written by Lisa Arvanitis, then the AstraZeneca project physician for Seroquel, stating, “I was really struck by how consistent the data was” from multiple patient studies showing weight gain “is more rapid initially,” but continues for at least a year.

“It doesn’t stop,” she wrote. “The other issue of what we tell the sales force is more problematic.”

Meanwhile, a memo a few months earlier from an AstraZeneca “commercial strategist,” Richard Lawrence, discusses one patient study presented at a meeting of doctors and states, “Lisa has done a great ‘smoke-and-mirrors’ job!”

The company “could put a positive spin (in terms of safety) on this cursed study,” Lawrence adds.

Plaintiffs’ lawyers say that until very recently, the company’s warnings were buried far down in the lengthy package insert, rather than being put prominently at the top of it.

Thousands of Seroquel lawsuits filed in federal courts have been consolidated under one judge in Orlando, Fla. Others are filed in state courts in New York, New Jersey and Delaware, where AstraZeneca has its U.S. headquarters.

Blizzard and his colleagues, after obtaining the documents in the course of the litigation, have been seeking since August 2007 to get them released, but AstraZeneca officials had argued they were confidential.

On Thursday, just before a hearing at which the company’s lawyers were to have to prove to a federal judge why 111 different documents should not be released, AstraZeneca agreed to release 102 of them, Blizzard said.

Some of the unsealed documents indicate a further problem for AstraZeneca’s sales representatives: Study after study showed Seroquel was not as effective as competing drugs in the same class, including Eli Lilly & Co.’s Zyprexa.

Meanwhile, AstraZeneca said Friday that the FDA has asked for additional information about the safety and effectiveness of a newer version of the drug, Seroquel XR extended release tablets. That version is proved for schizophrenia and bipolar disorder, but the company is seeking approval to market it for anxiety and major depression.

  1. A very horrific side- affect, very visable.
    Too bad many other horrible, life altering side -affects are not seen for many years, sometimes too late. And lets not forget, suicide “ideaogly”.
    This crap is too far gone, and we must fight to reverse the widespread use and acceptance of it.

  2. Terry Walker

    My sister Debbie Walker (deceased) and I had the same toxic reaction to paroxetine (malignant neoplasms of the brain). Debbie had been put on oxycontin to deal with the pain and discontinued it on her own seeing how I was able to get by having refused all medications offered by various doctors. Debbie ended up at East General hopital trying to get help; (she told me that she was put in a room her clothes were stripped from her body). She requested that I go and talk to the doctors about this disorder paxil induced in us. I went and discussed how Debbie should have the same test that I had been given while at Baycrest Hopital; they told my sister I did not know what I was talking about. Debbie was put on a mood stabilizers and seroquel, she gain 40-50 pounds.
    Everything I know is on reputable internet sites. Our problem is Doctors and Government with their lawyers refuse to educate themselves and live in pre internet era.
