How Pharmaceutical Innovation Is Affected By Data Exclusivity Periods

Pharmaceutical companies and generic drug manufacturers have long been at odds over regulations about "data exclusivity," the period of time before generic manufacturers can make use of valuable clinical trial data.

A new study in the January 2011 issue of Health Affairs is the first to calculate the financial and social costs of limiting access to trial data - and finds that extending the term of exclusive access will lead to higher drug costs in the short term but also to more than 200 extra drug approvals and to greater life expectancy in the next several decades.

"Elected officials are unlikely to embrace legislation that would result in higher drug prices, but our research suggests that legislation to extend data exclusivity would spur innovation that would benefit future generations," explained Dana Goldman, lead author, director of the Schaeffer Center for Health Policy and Economics at USC and Norman Topping Chair in Medicine and Public Policy at USC.
