Manufacturer Tells Doctor to Stop Talking About Avandia Risks
A November 20, 2008, Philadelphia Inquirer article discusses how a Maryland doctor said she felt “threatened and disappointed” after GlaxoSmithKline P.L.C. urged her to stop discussing her concerns that the company’s diabetes drug, Avandia, caused heart problems.
The doctor’s claim marks the second time that GlaxoSmithKline has been accused of trying to intimidate a researcher who pointed out problems associated with Avandia, which before its side effects became well-known was the top-selling diabetes drug. In 2007, University of North Carolina researcher John Buse testified before Congress that GlaxoSmithKline had called him a liar and suggested it might sue him if his comments about Avandia’s potential safety problems caused the company’s stock to drop.
On November 19, 2008, GlaxoSmithKline, a London company that has large operations in the Philadelphia area, said it had taken appropriate action when Mary Money, an internist in Hagerstown, Md., told the company of repeated instances of congestive heart failure and dangerous fluid retention in patients taking Avandia.
“GSK did not dispute the occurrence of adverse events observed by this physician. In fact, GSK promptly shared the information with the Food and Drug Administration and conducted its own scientific analyses,” the company said in a statement.
The company also said its label at the time Money had raised her concerns included warnings about the risk of congestive heart failure. Those warnings were strengthened in later years as more evidence emerged about heart problems. The drug’s label now includes a black-box warning, the FDA’s strongest.
The new assertions were first reported in the November 19, 2008, Wall Street Journal.
Money and Stephen Lippman, a doctor she worked with who also was head of the diabetes program at the local hospital, Washington County Hospital, said in interviews that the company had failed to take their concerns seriously.
Money said her concerns began in the fall of 1999, after a patient she had put on Avandia developed congestive heart failure and “massive fluid retention. I was just barely able to keep her out of the hospital.”
The patient’s problems disappeared when Money took her off Avandia. Soon, more patients developed the same problems after they started taking Avandia.
She took her concerns to Lippman, who found additional patients with the same side effects after starting Avandia. Together, they collected data on 85 patients, about half of whom had significant edema, or fluid retention and swelling. Edema can indicate heart problems.
In April 2000, Money and Lippman met with GlaxoSmithKline representatives. She said a GlaxoSmithKline physician she identified as Daniel Everitt, who now works for Centocor Inc., of Horsham, attended in person. A Centocor spokesman said yesterday that Everitt declined to comment.
Money also said Martin St. John Sutton, a cardiologist at the University of Pennsylvania, had participated in the meeting by phone. Sutton did not return a call seeking comment.
After the meeting, GlaxoSmithKline asked the hospital’s chief of staff, in a letter, to make sure his doctors did not disseminate “unsubstantiated” information about Avandia.
Money said she expected to hear back directly from GlaxoSmithKline after the meeting, but did not until the hospital’s chief of staff told her about the letter from the company.
Mary Anne Rhyne, a spokeswoman for GlaxoSmithKline, said in a statement that the letter was necessary. “When GSK learns about statements by physicians that are inconsistent with the scientific data on its medicines, we have the responsibility to do what we can to correct these inaccuracies for the benefit of physicians, patients and scientific discourse,” the statement said.
“After first discussing these issues in great detail with Dr. Money, GSK wrote a letter to Washington County Hospital because Dr. Money’s unsubstantiated theory had been shared with all of the departments and medical staff at the hospital.”
Money said she interpreted the letter as an effort to silence her and Lippman.
“I guess I was quite naive,” she said. “I thought that the drug company would want to know that their drug was at risk of harming patients.”
She said she felt vindicated last year when Steven Nissen of the Cleveland Clinic published research in the New England Journal of Medicine saying that Avandia could increase the risk of heart attack 43%.
Nissen said that GlaxoSmithKline had always treated him respectfully, even when it disagreed with him. Nissen has consulted for several drug companies, including GlaxoSmithKline.
Lippman said the meeting with GlaxoSmithKline representatives and subsequent letter had disturbed him.
“The problem with [the] drug system is that if people on the front line feel that they’re going to get humiliated for bringing up questions, they’re not going to report things and they are not going to be the canary in the coal mine,” Lippman said. “The issue is that whatever the 800-pound gorilla thought they were doing, it was intimidating.”
Sen. Charles Grassley (R., Iowa) is expected in the next few weeks to release results of an investigation into GlaxoSmithKline’s handling of Avandia.
Avandia has attracted many critics, including the consumer group Public Citizen, which has asked the FDA to take the drug off the market. This week, John Jenkins, director of the FDA’s Office of New Drugs, told Reuters that his agency was looking more carefully at the rise of heart risks related to drugs, including Avandia, that treat chronic conditions.
Some doctors say they believe Avandia helps some patients and should remain on the market.
Zachary T. Bloomgarden, an endocrinologist at Mount Sinai Medical Center in New York, said Avandia could help reduce serious health problems in diabetic patients who do not respond as well to other treatments. He also has received grants and fees from many drug companies, including GlaxoSmithKline.
