(1) Worldwide, there are an estimated 6000 to 7000 rare diseases. Patients face special difficulties in obtaining an accurate diagnosis, adequate information about the disease, and access to qualified specialists. (2) Drug companies do not spontaneously conduct research on drugs for rare diseases, mainly because of the limited market for each indication. Only a few dozen of these drugs were available in France before 2000. (3) In 2000 the European Union adopted a Regulation, based on experience in the United States, aimed at promoting the development of drugs for patients suffering from rare diseases, i.e. 'orphan drugs'. (4) In Europe, orphan drug status can be granted when the prevalence of the disease does not exceed 5 cases per 10 000 inhabitants (or when it is more frequent but profitability is likely to be inadequate). (5) Companies that market an orphan drug receive a variety of financial assistance as well as a 10-year marketing monopoly. (6) Between April 2000 and April 2005, 268 medicinal products received European orphan drug status and 22 were granted European marketing authorization. (7) Access to these drugs varies greatly from one European Union Member State to another, mainly because of the high annual treatment costs (up to 300 000 euros per patient). Worldwide sales of the orphan drug imatinib reached more than two thousand million dollars in 2005. (8) Our systematic analyses (see the New Products column of our French edition la revue Prescrire) show that only 5 drugs which received European orphan drug status before May 2005 were for diseases for which there had previously been no treatment. (9) Clinical evaluation of orphan drugs is hindered by the small number of patients available for clinical trials. Some orphan drugs are adequately tested before being brought to market. Others are not compared to existing treatments. In many cases, surrogate criteria are used instead of clinical endpoints. These methodological flaws are in no way limited to orphan drugs. (10) Not all orphan drugs represent therapeutic advances. Clinical research and evaluation should continue after marketing authorization has been granted. (11) More drugs, with better-documented efficacy and safety, are now available for patients who previously had no effective treatment options. Yet there is too much duplication and too little evaluation, and too many drugs are extremely expensive, meaning that patients in many European countries cannot benefit. And many rare diseases are still neglected. 相似文献

With the assignment of the 500th European Union orphan drug designation in 2007, the Regulation on Orphan Medicinal Products truly begins to show its potential for delivering new medicines to patients with rare diseases. Here, we analysed European orphan drug development at a national level and unveil a strong relationship between orphan drug development and pharmaceutical innovation performance in Europe. Moreover, we identify gaps in transition from science into orphan drug development as important bottlenecks that exist in several European countries. Our findings underline the importance of innovation-based policies to enhance the development of orphan drugs in Europe. 相似文献

BackgroundRare diseases are chronic, serious, and life-threatening conditions that have not received sufficient attention from drug developers due to their rarity. Policies have been implemented to encourage research and incentivize the development of orphan drugs. However, the implementation of these policies has been inconsistent worldwide.ObjectiveThe primary aim of this study was to compare orphan drug policies in the United States, Europe, and Saudi Arabia (SA) and assess their impact on the number of approved indications.MethodLists of all drugs granted orphan designations and authorized for marketing in the United States, European Union, and SA were extracted using orphan drug lists available in regulatory body databases. The availability of these drugs, regarding their approval for orphan indication and designation, was assessed and classified using Anatomical Therapeutic Chemical codes.ResultA total of 792 orphan drug designations with at least one authorized indication were identified in this study. Of these, 92% were designated by the Food and Drug Administration (FDA), and 27% were designated by the European Medicine Agency (EMA). The FDA, EMA, and Saudi Food and Drug Authority approved 753, 435, and 253 orphan drugs, respectively.ConclusionFewer orphan drug approvals were found in SA than in the United States and Europe. This highlights the need to focus on rare diseases and orphan drugs and for policies to be created in SA to attract pharmaceutical markets and fulfill unmet orphan drug approval needs. 相似文献

Orphan drugs are intended for diseases with a very low prevalence, and many countries have implemented legislation to support market access of orphan drugs. We argue that it is time to revisit the special market access status of orphan drugs. Indeed, evidence suggests that there is no societal preference for treating rare diseases. Although society appears to assign a greater value to severity of disease, this criterion is equally relevant to many common diseases. Furthermore, the criterion of equity in access to treatment, which underpins orphan drug legislation, puts more value on health improvement in rare diseases than in common diseases and implies that population health is not maximized. Finally, incentives for the development, pricing and reimbursement of orphan drugs have created market failures, including monopolistic prices and the artificial creation of rare diseases. We argue that, instead of awarding special market access status to orphan drugs, there is scope to optimize research and development (R&D) of orphan drugs and to control prices of orphan drugs by means of, for example, patent auctions, advance purchase commitments, pay-as-you-go schemes and dose-modification studies. Governments should consider carefully the right incentive strategy for R&D of orphan drugs in rare diseases. 相似文献

Rare diseases are an important global public health issue. One significant challenge is to ensure the access to orphan drugs for patients with rare disease. This study aims to evaluate the accessibility of orphan drugs in China. Information pertaining to the availability and costs of each orphan drug in each hospital was obtained from the Chinese Medicine Economic Information database during 2011-2017. We measured the accessibility of orphan drugs from 3 aspects: availability, daily costs, and affordability to patients.The market availability rate of orphan drugs in China was 28.8% by June 30, 2017. The median availability rate at the hospital level was less than 15% but was increasing over time. The cost of a defined daily dose of orphan drugs varied significantly with a decreasing trend in all areas. Less than half of all surveyed orphan drugs had a cost of a defined daily dose no more than residents' average daily income.This study reveals the challenges of access to orphan drugs in China. The availability of marketed orphan drugs in China was relatively low and most orphan drugs placed a heavy financial burden on patients with rare disease. It is necessary to develop legislation for orphan drugs and encourage domestic generics. 相似文献

Sustained advocacy efforts driven by patients' organizations to make rare diseases a health priority have led to regulatory and economic incentives for industry to develop drugs for these diseases, known as orphan drugs. These incentives, enacted in regulations first introduced in the United States in 1983 and later in Japan, Europe and elsewhere, have resulted in substantial improvements in the treatment for patients with a range of rare diseases. However, the advent of orphan drug development has also triggered several questions, from the definition of rarity to the pricing of orphan drugs and their impact on health-care systems. This article provides an industry perspective on some of the common questions and misconceptions related to orphan drug development and its regulation, with the aim of facilitating future progress in the field. 相似文献

目的:为建立我国罕见病患者医药保障体系提供建议。方法:通过研究国外罕见病药物(孤儿药)研发政策和罕见病患者医药保障法律,找到我国与其他国家罕见病诊治和保障体系之间的差距和不足,并依照我国国情和医疗现状,提出建立我国罕见病患者保障体系的建议。结果:经过系统数据收集和分析后发现,发达国家和地区都有特定的部门负责制定和执行罕见病法律,罕见病的定义明确,制定了孤儿药研发的鼓励性政策并提供经费支持,罕见病的药物研发取得了极大进展,研发的积极性和研发的速度均得到了很大提高。同时,这些国家和地区的孤儿药支付体系比较健全,建立了国家基金、医疗、社会、商业保险等多重渠道不同比例的报销机制。相对来说,我国罕见病患者生存现状不佳,诊治状况不容乐观,用药不规范、依从性低。造成这些现象的原因包括治疗费用高而报销比例低,未引进相关治疗药物,供药不及时或停止供应,误诊率高等等。结论:建立我国罕见病患者保障体系是一项艰巨的工作,应从3个方面展开:一是明确我国罕见病和罕见病用药的定义、完善罕见病立法;二是将孤儿药,特别是通过药品治疗可以治愈的,以及针对儿童罕见病的药品纳入医疗保险,从而提高孤儿药的可及性;三是建立罕见病诊疗流程,提高罕见病的诊疗水平。 相似文献

Orphan drug development is progressing too slowly 总被引:2,自引:0,他引:2
AIMS: To assess the methodological quality of OMP dossiers and to discuss possible reasons for the small number of products licensed. METHODS: Information about orphan drug designation and approval was obtained from the website of the European Commission-Enterprise and Industry DG and from the European Public Assessment Reports. RESULTS: Out of 255 OMP designations, only 18 were approved (7.1%). Their dossiers often showed methodological limitations such as inappropriate clinical design, lack of active comparator where available and use of surrogate end-points. CONCLUSIONS: The paucity of European incentives for manufacturers and the poor documentation underpinning the applications may have limited the number of new OMP. The over 5000 rare diseases awaiting therapy are an important public health issue. 相似文献

Changes in regulatory policy and legislative incentives to promote the development of drugs for rare diseases - orphan drugs - have led to increases in the number of orphan drug designations, but the rate of such products reaching the market remains frustratingly flat. This article highlights areas in which novel approaches could facilitate regulatory approval and access to treatments for rare diseases. 相似文献

Orphan drug incentives have stimulated research into diseases with significant unmet medical need. Although the targeting of orphan diseases is seen by industry as an attractive strategy, there are limited economic data available to support its use. In this paper we show that the revenue-generating potential of orphan drugs is as great as for non-orphan drugs, even though patient populations for rare diseases are significantly smaller. Moreover, we suggest that orphan drugs have greater profitability when considered in the full context of developmental drivers including government financial incentives, smaller clinical trial sizes, shorter clinical trial times and higher rates of regulatory success. The data support the targeting of rare diseases as an important component of a successful biopharma R&D strategy. 相似文献
