The research and development costs of 68 randomly selected new drugs were obtained from a survey of 10 pharmaceutical firms. These data were used to estimate the average pre-tax cost of new drug development. The costs of compounds abandoned during testing were linked to the costs of compounds that obtained marketing approval. The estimated average out-of-pocket cost per new drug is 403 million US dollars (2000 dollars). Capitalizing out-of-pocket costs to the point of marketing approval at a real discount rate of 11% yields a total pre-approval cost estimate of 802 million US dollars (2000 dollars). When compared to the results of an earlier study with a similar methodology, total capitalized costs were shown to have increased at an annual rate of 7.4% above general price inflation.
从对10家制药公司的调查中获取了68种随机选择的新药的研发成本。这些数据用于估算新药研发的平均税前成本。测试期间被放弃的化合物成本与获得上市批准的化合物成本相关联。估计每种新药的平均自付成本为4.03亿美元(2000年美元)。以11%的实际贴现率将自付成本资本化至上市批准时,得出的批准前总成本估计为8.02亿美元(2000年美元)。与早期采用类似方法的研究结果相比,总资本化成本显示以高于一般物价通胀率7.4%的年增长率增长。
