More than 1,000 studies haven’t even begun, hundreds more are incomplete, and some of the promised research has been pending for years — or simply cancelled.
As part of their approval for new products, drug makers often agree to perform additional research into safety, dosing and other concerns after the drugs come to market. The research, called a Phase IV trial, is usually voluntary, but frequently is neither officially scheduled, nor is it policed to assure completion by the FDA.
Over the past couple of years, lawmakers began making noises around Washington about the staggering numbers of incomplete studies. And in March, the Government Accountability Office (GAO), spurred by Sen. Charles Grassley (R-IA), launched an investigation into the nature of FDA drug approvals and FDA-ordered post-marketing studies.
In late April, the FDA released figures detailing the status of all the studies on its books, and the statistics are depressing, to say the least, for doctors and patients. The agency’s summary reveals that 1,044, or 62 percent, of incomplete studies for drugs and biotechs had yet to be started as of Sept. 30, 2007. A year earlier, reports Bloomberg News, 1,026, or 63 percent, of unfinished studies hadn’t yet begun. So the situation is actually worsening — we’re 1 percent better, but in total, we’re further behind.
Last September, President Bush signed the Food and Drug Administration Amendments Act (FDAAA) of 2007 into law, which allows the FDA to legally require certain post-approval studies. In fact, under the new law, the agency can fine companies up to $1 million for failing to perform those studies. Grassley argued for higher fines, and in his request to the GAO asked if the FDA needs even more authority to compel the studies.
The Pharmaceutical Research and Manufacturers of America, one of Big Pharma’s lobbying groups in Washington, responded to Bloomberg that studies can “take a long time to begin because of discussions with the FDA over how they should be conducted”, adding that enrolling patients in studies can be difficult, too. Not surprisingly, they didn’t mention that the substantial costs of many Phase IV trials may be the real reason for the delays.
And an FDA spokesperson said it is considering how to “integrate” its new power to require studies with commitments that have been made by drug makers. The FDA’s Susan Cruzan told Bloomberg that “they will work to ensure that previously promised studies are completed in a timely manner.” Just what a “timely manner” might mean is yet to be defined.
It’s been two months since the FDA released the statistics, and 10 months since the Act was signed. Pharmaceutical safety is an immense public issue, and there’s been plenty of time for the agency to start flexing its new muscles. But were still hearing double-speak from Big Pharma and the FDA.
