INFORMATION PLEASE

One response is for manufacturers to inform FDA in advance of supply problems. The agency reports that early warnings helped it head off 38 potential shortages in 2010 and 99 so far this year. When FDA knows of a looming supply interruption, its staff can expedite the review and approval of supplements for new suppliers, alternative production sites and changes in specifications—actions responsible for most (84) shortage preventions this year. Sometimes, FDA can bend the rules to permit continued marketing of a violative product with some corrective action. And the agency has had some success in encouraging other firms to ramp up production or to enter a market through speedy regulatory actions.

FDA also has approved temporary importation of unapproved sources to fill supply gaps, a strategy that helped alleviate shortages this year in several cancer drugs. APP Pharmaceuticals worked with FDA to reduce a shortage of the widely used anesthetic propofol by importing the product from Germany.

Unfortunately, FDA often lacks information on looming shortages because, under current law, only sole-source manufacturers of critical medicines have to notify FDA of plans to discontinue production. Some companies voluntarily inform FDA of problems likely to lead to short supplies, but most do not, and often the information comes in too late for timely resolution.

To remedy this limitation, Congress is looking to enact legislation that would require six-months advance notification of production changes for a broad range of prescription drugs. Rep. Diana DeGette (D-CO) has bipartisan support for legislation in the House, and Sens. Amy Klobuchar (D-MN), and Robert Casey (D-PA) lead the early-notification campaign in the Senate. They propose leeway for manufacturers who show that a manufacturing problem could not be anticipated, as well as penalties for failure to comply. A related proposal requires manufacturers to inform FDA of situations that make a product vulnerable to shortages, such as a single API source, to highlight the need for back-up emergency sources.

Although advance notification may help FDA head off some shortages, the danger is that wider release of such information could lead to hoarding and price gouging. Gray-market profiteers are inundating health professionals with faxes and phone calls offering scarce drugs at huge markups. Rep. Elijah Cummings of Maryland, top Democrat on the House Oversight and Government Reform Committee, launched an investigation of secondary distributors last month, seeking information on sources and profits for certain drugs. His targets include high-priced offers of leukemia treatment cytarabine by Allied Medical Supply (Florida); Superior Medical Supply (Colorado) offers for paclitaxel; Premium Health Services (Maryland) sales of leucovorin; fluorouracil offers from PRN Pharmaceuticals (Maryland); and Reliance Wholesale (Florida) marketing of magnesium sulfate.

To avoid profiteering, FDA wants to be informed by manufacturers of possible shortage situations, but doesn't necessarily want to make that information public right away, noted Sandra Kweder, deputy director of CDER's Office of New Drugs at the House hearing. The agency first wants to assess if the problem is real, its likely impact, and what actions can be taken to mitigate difficulties. "Early notification to FDA is a very useful tool," said Kweder, "but it's different from early publication."

Advance notification is not always possible. FDA officials concede that many manufacturing problems cannot be anticipated (e.g., equipment breakdowns and plant fires, and earthquakes, volcanoes, and other natural disasters)can suddenly disrupt supplies and material transport.
