Drug Approval

药物批准
  • 文章类型: Journal Article
    研究表明药物研究与疾病负担之间存在不匹配。在欧盟进行的一项研究发现,新药开发仅限于某些疾病。印度一项关于生物类似药批准的研究发现,87%的药物用于治疗非传染性疾病。这项研究旨在确定2017年至2021年在印度批准的新药以及发病率和死亡率的十大原因,并检测两者之间是否存在任何不一致。
    使用从中央药物标准控制组织网站访问的新药批准数据进行了描述性研究。从全球疾病负担数据库中确定了2015年至2019年印度十大死亡和发病原因。描述性统计用于比较药物批准和主要疾病。
    在研究期间批准了126种药物。抗肿瘤药物占批准的19.84%,抗菌药物18.25%,和心血管药物9.52%。缺血性心脏病和慢性阻塞性肺疾病是发病率和死亡率的两个主要原因。腹泻病,下呼吸道感染,药物敏感结核病是十大原因之一。十种抗菌药物,包括四种抗结核药物,在此期间获得批准。两种药物被批准用于罕见疾病。
    我们的研究表明,批准的药物在很大程度上符合普遍的疾病负担,并且没有观察到明显的不一致。一些疾病,如缺血性卒中/颅内出血,需要进一步努力提出新的药物治疗方案。
    UNASSIGNED: Studies show the presence of a mismatch between drug research and disease burden. A study conducted in the European Union found that new drug development was restricted to certain diseases. A study of biosimilar approvals in India found that 87% of drugs were for treating noncommunicable diseases. This study aimed to determine the new drugs approved in India from 2017 to 2021 and the top ten causes of morbidity and mortality and detect the presence of any discordance between these.
    UNASSIGNED: A descriptive study was conducted using data on new drug approvals accessed from the Central Drugs Standard Control Organization website. The top ten causes of mortality and morbidity in India from 2015 to 2019 were identified from the Global Burden of Diseases database. Descriptive statistics were used to compare the drug approvals and the leading diseases.
    UNASSIGNED: One hundred twenty-six drugs were approved during the study period. Antineoplastic drugs constituted 19.84% of the approvals, antimicrobials 18.25%, and cardiovascular drugs 9.52%. Ischemic heart disease and chronic obstructive pulmonary disease were the two leading causes of morbidity and mortality. Diarrheal diseases, lower respiratory tract infection, and drug-susceptible tuberculosis were among the top ten causes. Ten antibacterials, including four antitubercular drugs, were approved during this period. Two drugs were approved for rare diseases.
    UNASSIGNED: Our study showed that the drugs approved were largely in line with the prevalent disease burden, and there was no significant discordance observed. Some diseases, such as ischemic stroke/intracranial hemorrhage, require further efforts in bringing forth newer pharmacotherapy options.

    本文介绍了药物输送装置开发商(DDDD)采用的策略,以支持药物-装置组合产品的缩写新药申请(ANDA)提交。根据FDA相关指南,应编制阈值分析。如果确定了参考上市药物(RLD)和通用药物器械之间的“其他差异”,可能需要进行比较使用人为因素(CUHF)研究。
    DDDD进行了任务分析和物理比较,以评估笔式注射器设计的差异。然后,我们进行了一项形成性CUHF研究,其中25名参与者使用RLD和通用笔式注射器模拟注射.
    每位参与者完成四次模拟注射后,在RLD(0.70)和通用(0.68)笔式注射器之间观察到相似的类型和使用错误率.
    DDDD可以通过启动设备的比较任务分析和物理比较作为阈值分析的输入,支持制药公司在其药物-设备组合产品的ANDA提交策略中。如果识别出\'其他差异\',可以进行形成性CUHF研究。如我们的案例研究所示,这种方法可用于支持最终组合产品的CUHF研究的样本量计算和非劣效性确定.
    UNASSIGNED: This article presents a strategy that a Drug Delivery Device Developer (DDDD) has adopted to support Abbreviated New Drug Application (ANDA) submissions of drug-device combination products. As per the related FDA guidance, a threshold analysis should be compiled. If \'other differences\' between the Reference Listed Drug (RLD) and the generic drug devices are identified, a Comparative Use Human Factors (CUHF) study may be requested.
    UNASSIGNED: The DDDD performed task analysis and physical comparison to assess the pen injector design differences. Then, a formative CUHF study with 25 participants simulating injections using both RLD and the generic pen injectors was conducted.
    UNASSIGNED: After each participant completed four simulated injections, similar type and rates of use error between the RLD (0.70) and generic (0.68) pen injectors were observed.
    UNASSIGNED: DDDDs can support pharmaceutical companies in the ANDA submission strategy of their drug-device combination product by initiating comparative task analysis and physical comparison of the device as inputs for the threshold analysis. If \'other differences\' are identified, a formative CUHF study can be performed. As shown in our case study, this approach can be leveraged to support the sample size calculation and non-inferiority margin determination for a CUHF study with the final combination product.

    美国抗生素市场失灵已经威胁到未来的创新和供应。了解临床医生何时以及为何未充分利用最近批准的革兰氏阴性抗生素可能有助于在未来的抗生素开发和潜在的市场进入奖励中优先考虑患者。
    为了确定最近美国食品和药物管理局(FDA)批准的革兰氏阴性抗生素(头孢他啶-阿维巴坦,头孢洛赞-他唑巴坦,美罗培南-瓦巴坦,plazomicin,eravacycline,亚胺培南-来巴坦-西司他丁,和头孢地洛),并确定与它们的优先使用相关的因素(相对于传统的仿制药)在革兰氏阴性感染患者中表现出难以治疗的耐药性(DTR;也就是说,对所有一线抗生素的耐药性)。
    回顾性队列。
    619家美国医院。
    成人住院患者。
    使用加权线性回归计算抗生素使用的季度百分比变化。机器学习选择的候选变量,和混合模型确定了与新(vs.传统)抗生素在DTR感染中的使用。
    在2016年第1季度至2021年第2季度之间,头孢特洛扎-他唑巴坦(2014年批准)和头孢他啶-阿维巴坦(2015年)主导了新的抗生素使用,而随后批准的革兰氏阴性抗生素的吸收相对缓慢。在革兰氏阴性感染住院患者中,0.7%(2551[2631发作],共362142次)显示DTR病原体。在2631例DTR发作中,有1091例患者仅使用传统药物治疗(41.5%),包括“储备”抗生素,如多粘菌素,氨基糖苷类,和替加环素在1091例发作中的865例(79.3%)。有菌血症和慢性疾病的患者有更大的调整概率和那些没有复苏状态的患者,急性肝功能衰竭,和鲍曼不动杆菌复合体和其他非假性非发酵罐病原体接受更新的调整概率较低(与传统的)用于DTR感染的抗生素,分别。新抗生素药敏试验的可用性增加了使用的可能性。
    残余混杂。
    尽管FDA在2014年至2019年之间批准了7种下一代革兰氏阴性抗生素,但临床医生仍经常使用老年人治疗耐药革兰氏阴性感染,安全性-疗效欠佳的通用抗生素。未来抗生素具有针对未开发病原体生态位的创新机制,广泛可用的敏感性测试,证明耐药感染结局改善的证据可能会提高利用率。

    UNASSIGNED: The U.S. antibiotic market failure has threatened future innovation and supply. Understanding when and why clinicians underutilize recently approved gram-negative antibiotics might help prioritize the patient in future antibiotic development and potential market entry rewards.
    UNASSIGNED: To determine use patterns of recently U.S. Food and Drug Administration (FDA)-approved gram-negative antibiotics (ceftazidime-avibactam, ceftolozane-tazobactam, meropenem-vaborbactam, plazomicin, eravacycline, imipenem-relebactam-cilastatin, and cefiderocol) and identify factors associated with their preferential use (over traditional generic agents) in patients with gram-negative infections due to pathogens displaying difficult-to-treat resistance (DTR; that is, resistance to all first-line antibiotics).
    UNASSIGNED: Retrospective cohort.
    UNASSIGNED: 619 U.S. hospitals.
    UNASSIGNED: Adult inpatients.
    UNASSIGNED: Quarterly percentage change in antibiotic use was calculated using weighted linear regression. Machine learning selected candidate variables, and mixed models identified factors associated with new (vs. traditional) antibiotic use in DTR infections.
    UNASSIGNED: Between quarter 1 of 2016 and quarter 2 of 2021, ceftolozane-tazobactam (approved 2014) and ceftazidime-avibactam (2015) predominated new antibiotic usage whereas subsequently approved gram-negative antibiotics saw relatively sluggish uptake. Among gram-negative infection hospitalizations, 0.7% (2551 [2631 episodes] of 362 142) displayed DTR pathogens. Patients were treated exclusively using traditional agents in 1091 of 2631 DTR episodes (41.5%), including \"reserve\" antibiotics such as polymyxins, aminoglycosides, and tigecycline in 865 of 1091 episodes (79.3%). Patients with bacteremia and chronic diseases had greater adjusted probabilities and those with do-not-resuscitate status, acute liver failure, and Acinetobacter baumannii complex and other nonpseudomonal nonfermenter pathogens had lower adjusted probabilities of receiving newer (vs. traditional) antibiotics for DTR infections, respectively. Availability of susceptibility testing for new antibiotics increased probability of usage.
    UNASSIGNED: Residual confounding.
    UNASSIGNED: Despite FDA approval of 7 next-generation gram-negative antibiotics between 2014 and 2019, clinicians still frequently treat resistant gram-negative infections with older, generic antibiotics with suboptimal safety-efficacy profiles. Future antibiotics with innovative mechanisms targeting untapped pathogen niches, widely available susceptibility testing, and evidence demonstrating improved outcomes in resistant infections might enhance utilization.

    FDA于1992年启动,加速批准计划授予在罕见/危及生命的疾病中表明的药物以比传统轨道更快的速度销售的能力。每家制造公司都向FDA提交其药物,并在60天内确定该药物是否符合此路径。许多最初通过这种途径获得批准的药物,随后未证明其临床获益.癌症是导致死亡的主要原因,绝大多数已被批准/退出该途径的药物都在肿瘤学范围内。有各种各样的癌症亚型和治疗靶位点,这些药物已经被评估。在这里,是17种肿瘤药物的概述,跨越22个癌症相关的适应症,已在加速路线内获得批准,随后撤回。
    Launched in 1992, the FDA accelerated approval program grants drugs indicated in rare/life threatening diseases the ability to be marketed at a faster pace than through the traditional track. Each manufacturing company presents its drug to the FDA, and within 60 days it will determine if the drug is eligible for this path. Many drugs that were initially approved through this route, subsequently did not demonstrate their clinical benefits. With cancer being a leading cause of death, a vast majority of drugs that have been approved/withdrawn from this pathway are indicated within oncology. There are a wide variety of cancer subtypes and therapeutic target sites that these drugs have been evaluated for. Herein, is an overview of the 17 oncology drugs, spanning 22 cancer-related indications, that had been approved within the accelerated route and subsequently withdrawn.

    目的:评估肿瘤药物的附加效益和收入,探索他们的联系,并调查欧洲药品管理局(EMA)不同批准途径的附加收益和收入之间的潜在差异。
    方法:回顾性队列研究。
    方法:1995年至2020年EMA批准的肿瘤学药物及其适应症。
    方法:使用七个组织发布的评级来评估增加的益处:来自美国的卫生技术评估机构,法国,德国,意大利,两个医学肿瘤学会,还有一份药物公告.所有检索到的评级都使用四点排名量表重新分类,以指示负面或不可量化,未成年人,实质性的,或主要的额外好处。收入数据是从公开的财务报告中提取的,并与公开的研发(R&D)成本估算进行比较。最后,评估了附加收益与收入之间的关联。所有分析均在整个研究队列中进行,并在基于EMA批准途径的子组中:标准营销授权,有条件的营销授权,特殊情况下的授权。
    结果:至少一个组织在规定的时间范围内评估了131种具有166种适应症的肿瘤药物的额外益处。共产生458个附加获益评级;189个(41%)为阴性或不可量化.抵消研发成本中位数的时间中位数(6.84亿美元,5.35亿英镑,€60200万,调整到2020年值)为三年;55种药物中有50种(91%)在八年内收回了这些成本。具有较高附加效益评级的药物通常具有更大的收入。在特殊情况下,有条件的营销授权和授权的负面或不可量化的附加收益评级比标准的营销授权更为频繁(相对风险1.53,95%置信区间1.23至1.89)。与标准营销授权相比,有条件的营销授权产生的收入较低,抵消研发成本所需的时间更长(四年比三年)。
    结论:虽然收入似乎与附加收益一致,大多数肿瘤药物在几年内恢复研发成本,尽管几乎没有额外的好处。对于通过有条件上市许可批准的药物尤其如此,这本身似乎缺乏全面的证据。政策制定者应评估当前的监管和报销激励措施是否有效地促进为需求最大的患者开发最有效的药物。
    To evaluate the added benefit and revenues of oncology drugs, explore their association, and investigate potential discrepancies between added benefit and revenues across different approval pathways of the European Medicines Agency (EMA).
    Retrospective cohort study.
    Oncology drugs and their indications approved by the EMA between 1995 and 2020.
    Added benefit was evaluated using ratings published by seven organisations: health technology assessment agencies from the United States, France, Germany, and Italy, two medical oncology societies, and a drug bulletin. All retrieved ratings were recategorised using a four point ranking scale to indicate negative or non-quantifiable, minor, substantial, or major added benefit. Revenue data were extracted from publicly available financial reports and compared with published estimates of research and development (R&D) costs. Finally, the association between added benefit and revenue was evaluated. All analyses were performed within the overall study cohort, and within subgroups based on the EMA approval pathway: standard marketing authorisation, conditional marketing authorisation, and authorisation under exceptional circumstances.
    131 oncology drugs with 166 indications were evaluated for their added benefit by at least one organisation within the required timeframe, yielding a total of 458 added benefit ratings; 189 (41%) were negative or non-quantifiable. The median time to offset the median R&D costs ($684m, £535m, €602m, adjusted to 2020 values) was three years; 50 of 55 (91%) drugs recovered these costs within eight years. Drugs with higher added benefit ratings generally had greater revenues. Negative or non-quantifiable added benefit ratings were more frequent for conditional marketing authorisations and authorisations under exceptional circumstances than for standard marketing authorisations (relative risk 1.53, 95% confidence interval 1.23 to 1.89). Conditional marketing authorisations generated lower revenues and took longer to offset R&D costs than standard marketing authorisations (four years compared with three years).
    While revenues seem to align with added benefit, most oncology drugs recover R&D costs within a few years despite providing little added benefit. This is particularly true for drugs approved through conditional marketing authorisations, which inherently appear to lack comprehensive evidence. Policy makers should evaluate whether current regulatory and reimbursement incentives effectively promote development of the most effective drugs for patients with the greatest needs.

    目的:临床研究报告(CSR)是非常详细的文件,在药物审批过程中起着关键作用。虽然历史上没有公开,近年来,包括欧洲药品管理局(EMA)在内的主要实体,加拿大卫生部,美国食品和药物管理局(FDA)强调了企业社会责任可及性的重要性。本文的主要目标是确定支持可供公开下载的药物批准的CSR的比例以及通过研究赞助者有资格获得独立研究人员请求的比例。
    方法:这项横断面研究检查了行业赞助的临床试验中CSR的可及性,这些临床试验的结果已在FDA授权的2021年收入最高的30种药物的药品标签中报告。我们确定1)CSR是否可从公共存储库下载,以及2)根据试验赞助者的数据共享政策,CSR是否符合独立研究者的要求.
    结果:共有316项行业赞助的临床试验,其结果在30种样本药物的FDA授权药物标签中呈现。在这些试验中,CSR可从70(22%)公开下载,其中37种可在EMA获得,40种可在加拿大卫生部存储库获得。虽然制药公司平台没有提供CSR的直接下载,通过提交研究提案,研究者确认316项临床试验中183项(58%)的CSR符合独立研究者的要求.总的来说,218(69%)的样本临床试验具有可供公开下载的CSR和/或符合试验赞助商的要求。
    结论:CSR可从69%的临床试验中获得,这些临床试验支持30种药物的监管部门批准。然而,只有22%的CSR可以直接从监管机构下载,其余的需要一个正式的申请程序,以请求研究申办方访问CSR.
    OBJECTIVE: Clinical study reports (CSRs) are highly detailed documents that play a pivotal role in medicine approval processes. Though not historically publicly available, in recent years, major entities including the European Medicines Agency (EMA), Health Canada, and the US Food and Drug Administration (FDA) have highlighted the importance of CSR accessibility. The primary objective herein was to determine the proportion of CSRs that support medicine approvals available for public download as well as the proportion eligible for independent researcher request via the study sponsor.
    METHODS: This cross-sectional study examined the accessibility of CSRs from industry-sponsored clinical trials whose results were reported in the FDA-authorized drug labels of the top 30 highest-revenue medicines of 2021. We determined (1) whether the CSRs were available for download from a public repository, and (2) whether the CSRs were eligible for request by independent researchers based on trial sponsors\' data sharing policies.
    RESULTS: There were 316 industry-sponsored clinical trials with results presented in the FDA-authorized drug labels of the 30 sampled medicines. Of these trials, CSRs were available for public download from 70 (22%), with 37 available at EMA and 40 at Health Canada repositories. While pharmaceutical company platforms offered no direct downloads of CSRs, sponsors confirmed that CSRs from 183 (58%) of the 316 clinical trials were eligible for independent researcher request via the submission of a research proposal. Overall, 218 (69%) of the sampled clinical trials had CSRs available for public download and/or were eligible for request from the trial sponsor.
    CONCLUSIONS: CSRs were available from 69% of the clinical trials supporting regulatory approval of the 30 medicines sampled. However, only 22% of the CSRs were directly downloadable from regulatory agencies, the remaining required a formal application process to request access to the CSR from the study sponsor.
