Although increases in the inflation-adjusted prices of ethical drugs and perceived high prices of new drugs have been a con- P cern of congressional committees for over 30 years, the growing Federal role in paying for prescription drugs has increased the concern over the appro- priateness of prices relative to the costs of bringing new drugs to market. Specific policies of U.S. and other governments can alter the delicate balance between costs and returns to pharmaceutical R&D, with ramifications for the future health of Americans, for health care costs, and for the future of the U.S. pharmaceutical industry. OTA’s report focuses mainly on the economic side of the R&D process. Pharmaceutical R&D is an investment, and the principal characteristic of an investment is that money is spent today in the hopes of generating even more money in the future. Pharmaceutical R&D is a risky investment; therefore, high financial returns are necessary to induce companies to invest in researching new chemical entities. Changes in Federal policy that affect the cost, uncertainty and returns of pharmaceutical R&D may have dramatic effects on the investment patterns of the industry. Given this sensitivity to policy changes, careful consid- eration of the effects on R&D is needed. The specific request for this study came from the House Committee on Energy and Commerce and its Subcommittee on Health and the Environment. The Senate Committee on the Judiciary’s Subcommittee on Antitrust, Monopolies, and Business Rights endorsed the study. OTA was assisted in this study by an advisory panel of business, consumer, and academic leaders chaired by Frederick M. Scherer, Ph. D., Professor of Economics, John F.

Below is a brief synopsis of the study’s major conclusions: SUMMARY OF FINDINGS . Pharmaceutical R&D is a costly and risky business, but in recent years the financial rewards from R&D have more than offset its costs and risks. The average aftertax R&D cash outlay for each new drug that reached the market in the 1980s was about $65 million (in 1990 dollars). The R&D process took 12 years on average. The full aftertax cost of these outlays, compounded to their value on the day of market approval, was roughly $194 million (1990 dollars). The cost of bringing a new drug to market is very sensitive to changes in science and technology, shifts in the kinds of drugs under development and changes in the regulatory environment.
