The pharmaceutical industry is facing substantial criticism from many directions, including financial barriers to access to drugs in both developed and developing countries, high profits, spending on advertising and marketing, and other issues. Underlying these criticisms are fundamental questions about the value of the current patent-based drug development system. Six major problems with the patent system are (1) recovery of research costs by patent monopoly reduces access to drugs; (2) market demand rather than health needs determines research priorities; (3) resources between research and marketing are misallocated; (4) the market for drugs has inherent market failures; (5) overall investment in drug research and development is too low, compared with profits; and (6) the existing system discriminates against US patients. Potential solutions fall into 3 categories: change in drug pricing through either price controls or tiered pricing; change in drug industry structure through a "buy-out" pricing system or with the public sector acting as exclusive research funder; and change in development incentives through a disease burden incentive system, orphan drug approaches, or requiring new drugs to demonstrate improvement over existing products prior to US Food and Drug Administration approval. We recommend 4 complementary reforms: (1) having no requirement to test new drug products against existing products prior to approval but requiring rigorous comparative postapproval testing; (2) international tiered pricing and systematic safeguards to prevent flow-back; (3) increased government-funded research and buy-out for select conditions; and (4) targeted experiments using other approaches for health conditions in which there has been little progress and innovation over the last few decades.
制药行业正面临来自多方面的严厉批评,包括发达国家和发展中国家在获取药物方面存在的经济障碍、高额利润、广告和营销支出以及其他问题。这些批评背后存在着关于当前基于专利的药物研发体系价值的根本性问题。专利体系存在的六个主要问题是:(1)通过专利垄断收回研究成本会减少药物可及性;(2)市场需求而非健康需求决定研究重点;(3)研究与营销之间的资源分配不当;(4)药品市场存在内在的市场失灵;(5)与利润相比,药物研发的总体投资过低;(6)现有体系歧视美国患者。潜在的解决方案可分为三类:通过价格管制或分层定价改变药品定价;通过“买断”定价体系或让公共部门作为唯一研究资助者改变制药行业结构;通过疾病负担激励体系、孤儿药方法或要求新药在美国食品药品监督管理局批准前证明优于现有产品来改变研发激励措施。我们建议进行四项互补性改革:(1)在批准前不要求将新药产品与现有产品进行对比测试,但要求进行严格的批准后对比测试;(2)实行国际分层定价并建立系统性保障措施以防止回流;(3)增加政府资助的研究并针对特定病症进行买断;(4)针对过去几十年进展甚微且缺乏创新的健康状况,采用其他方法进行有针对性的试验。
