AN UPCOMING REPORT by the Federal Trade Commission shows that brand-name pharmaceutical makers continue to cut questionable deals with generic manufacturers that delay the introduction of cheaper drugs onto the market.

Such pay-for-delay arrangements hurt consumers and increase costs for federal programs such as Medicare and Medicaid, according to the report, a copy of which was obtained by the editorial board. These deals are not illegal, but they should be.

Pharmaceutical companies rightly enjoy strong protections for products that often take years and billions of dollars to develop. These protections were so strong at one point that they discouraged would-be competitors from jumping in. The Hatch-Waxman Act of 1984 meant to address this problem by allowing generics to market “bio-equivalent” drugs as long as they did not infringe on the brand-name drug’s patent; the generic could also proceed if it proved the brand-name patent was invalid. The goal was to enhance competition and lower drug prices. That goal is thwarted when brand-name manufacturers engage in the popular practice of paying generic-drug makers to keep their products off the market.

In 2004, the FTC did not identify a single settlement in a patent litigation matter involving drug makers that raised pay-for-delay concerns. In its new report, the agency points to 28 cases that bear the telltale signs of pay-for-delay, including “compensation to the generic manufacturer and a restriction on the generic manufacturer’s ability to market its product.”

Sens. Charles E. Grassley (R-Iowa) and Herb Kohl (D-Wis.) have introduced the Preserve Access to Affordable Generics Act to close the pay-for-delay loophole. The bill would make such schemes presumptively illegal and empower the FTC to challenge suspicious arrangements in federal court. The most recent version gives companies a chance to preserve certain deals if “clear and convincing evidence” proves that their “pro-competitive benefits outweigh the anti-competitive harms.” The Obama administration estimates that eliminating pay-for-delay could save the government $8.8 billion over 10 years; the Congressional Budget Office offers a dramatically more conservative savings estimate of roughly $3 billion over the same period.

The legislation should appeal to the deficit-reduction “supercommittee,” which has been tasked with identifying ways to cut the federal deficit.
