Vioxx Reactions – Statements from the Medical Community
Did you know?
VIOXX ® Worldwide sales in 2003 were $2.5 billion.
Shares of Merck & Co. plunged nearly 27 percent. Investors erased a stunning $26.8 billion from Merck's market capitalization and sent its shares down $12.07 to close at $33. The Whitehouse Station , N.J. , company was immediately hit with litigation which claimed the claimed the drug is defective and Merck failed to warn of health risks associated with VIOXX ® .
"Some of us in the medical profession have seen this coming and have been discussing this with patients," said Dr. Calvin Brown, an associate professor of rheumatology at Rush University Medical Center in Chicago . "Doctors phones across the city are ringing off the hook. I don't think Merck hid anything, but they saw the glass as half full. But many of us in the medical profession saw it as half empty."
"Today's announcement by Merck is the latest evidence that this family of drugs, the Cox-2 inhibitors, once referred to as super aspirins are turning out to be super disasters," said Dr. Sidney Wolfe, director of Public Citizen's Health Research Group. "In trying to be a good citizen, Merck ignores its checkered history with VIOXX ® ."
"While the cause of these results is uncertain at this time, they suggest an increased risk of confirmed cardiovascular events," Peter S. Kim, president of Merck Research Laboratories, said in a prepared statement. He added that "while we recognize that VIOXX ® benefited many patients, we believe this action is appropriate."
In the first 18 months of their study, Merck said there was no difference in the risk of heart attack or stroke in patients taking either VIOXX ® or a placebo.
"Beginning after 18 months, however, the risk of cardiovascular event did increase among those on VIOXX ® ," said Merck chairman and chief executive officer Raymond Gilmartin. "Accordingly, we are withdrawing VIOXX ® effective today. We are taking this action because we believe it best serves the interest of patients."
"Patients who are currently taking VIOXX ® should contact their health care providers to discuss discontinuing use of VIOXX ® and possible alternative treatments," Merck said.
"In this study, there was an increased relative risk for confirmed cardiovascular events, such as heart attack and stroke, beginning after 18 months of treatment in the patients taking VIOXX ® compared to those taking placebo," Merck said in a press release.
"Given the availability of alternative therapies, and the questions raised by the data, we concluded that a voluntary withdrawal (of VIOXX ® ) is the responsible course to take," Merck chief Gilmartin said.
"This is a very significant negative for Merck. Not only is this a nearly $3 billion drug, but it calls into question the future of one the key drugs in its pipeline, Arcoxia," said Scott Henry, an analyst at Oppenheimer & Co.
"Merck did the right thing by promptly reporting these findings to FDA and voluntarily withdrawing the product from the market," Acting FDA Commissioner Dr. Lester M. Crawford said in a statement.
"Although the risk that an individual patient would have a heart attack or stroke related to VIOXX ® is very small, the study that was halted suggests that, overall, patients taking the drug chronically face twice the risk of a heart attack compared to patients receiving a placebo."
