FDA Orders New Safety Labels for Rosiglitazone (Avandia) and Pioglitazone (Actos)

Jun 12, 2007

The FDA Commissioner Andrew C. von Eschenbach, M.D., told a congressional hearing that the FDA will beef up the cardiovascular warnings on the labels of both rosiglitazone (Avandia) and pioglitazone (Actos). Moreover, the FDA announced it will convene a safety panel on June 30 to review the cardiovascular risks of rosiglitazone.
Rep. Henry Waxman (D-Calif.) convened the hearing to investigate the FDA’s handling of rosiglitazone from its approval in 1999 through recent reports that linked the drug to increased risk of cardiovascular events.

In general, Dr. von Eschenbach defended the FDA’s handling of rosiglitazone, but he conceded that the agency asked for the label changes on May 23-two days after the New England Journal of Medicine published a meta-analysis that found a 43% increase in risk of myocardial infarction among patients taking rosiglitazone.

The lead author of that analysis — Steven E. Nissen, M.D., chairman of cardiovascular medicine at the Cleveland Clinic — was aggressively questioned by Republican members of the committee who accused Dr. Nissen of sensationalizing what they characterized as questionable findings.

The Republicans also grilled Dr. Nissen over his decision to share his concerns about the safety of rosiglitazone with Waxman in February.

Rep. Darrell E. Issa (R-Calif.) was prosecutorial as he repeatedly attempted to limit Dr. Nissen to "yes" or "no" answers. Issa said that if Dr. Nissen had safety concerns about the drug, he should have taken those concerns to the FDA, not to committee staff appointed by Democrats.

Several times Issa and other Republicans pressed Dr. Nissen about whether he had shared his findings with Democrats on the committee before the meta-analysis was published.

Dr. Nissen repeatedly stated that his interest in rosiglitazone was purely that of a physician-scientist, whose goal was to disseminate information to both physicians and patients.

Moncef Slaoui, Ph.D., chairman of research and development for GlaxoSmithKline, presented the company’s case testifying that rosiglitazone had demonstrated superiority over two diabetes drugs — metformin and sulfynurea — and that the company has gone out of its way to confirm the safety of rosiglitazone.

Dr. Slaoui testified that the interim results from the RECORD trial, published online last Thursday by the New England Journal of Medicine, provided reassuring data about the drug’s safety. The study did not find a significant increase in MIs, but found a significant increase in heart failure. But three accompanying editorials pointed out that although the data did not confirm the risk found in the earlier meta-analysis, neither did they refute that finding.

Index ranks U.S. health care 66th out of a possible 100: A majority of Americans say they are worried about their ability to afford health care services and would be willing to pay higher taxes to support universal health coverage, according to a recent national survey. The survey results are part of the first annual “Health Security Index” by Catholic Healthcare West. The index, which ranks Americans’ health security at 66 out of a possible 100, reflects a troubling portrait about issues such as health care affordability, access and prevention.  The survey also found that 65 percent of Americans are concerned about their ability to manage a chronic disease and 71 percent say they are not sure they could afford health insurance if they lost their job.  In addition to affordability being the top concern for Americans when it comes to health care, the study also found that 72 percent said they want universal coverage and 63 percent said universal health coverage is necessary even if it requires tax increases.  Health Care Survey (pdf)
