摘要

简介在临床研究中，伊伐卡夫托（IVA）通过减缓肺功能下降的速度，改变了囊性纤维化（CF）疾病的发展轨迹。长期实际数据有助于证实这种反应的持久性：这项非干预性纵向研究利用美国CF基金会患者登记处的数据，描述了接受IVA治疗的CF患者肺功能的年变化率。接受IVA治疗的队列包括年龄≥6岁、CF跨膜传导调节器（CFTR）-门控突变≥1个且在2012年1月31日至2018年12月31日期间开始接受IVA治疗的CF患者。年龄匹配的参照队列包括杂合子F508del-CFTR突变和最小功能突变（R117H除外）且未接受过CFTR调节剂治疗的CF患者。根据估计的倾向评分计算出的标准化死亡率 (SMR) 权重平衡了基线特征。我们估算了5年中1 s内用力呼气容积预测值百分比（ppFEV1）的年化变化率，并以此计算了IVA治疗组与对照组的肺功能相对年化变化率：结果：在为期5年的随访中，经过SMR加权后，IVA治疗组有548人，对照组有541人。5年间，IVA治疗组和对照组的ppFEV1年化变化率分别为-1.23（95% CI -1.45, -1.03）和-2.03（-2.16, -1.90）个百分点。5年中，IVA治疗组与对照组相比，肺功能下降率降低了39%（95% CI：28，50）。这些结果与较短随访期的结果基本一致：IVA可在5年内减缓肺功能下降的速度，从而显示出持久的临床益处。结果表明，IVA对CF患者的肺功能轨迹具有持续、一致的影响。字数：300（字数限制：300字）。

A Retrospective, Longitudinal Registry Study on the Long-Term Durability of Ivacaftor Treatment in People with Cystic Fibrosis.

Introduction: Ivacaftor (IVA) has been shown to change the trajectory of cystic fibrosis (CF) disease progression by slowing the rate of lung function decline in clinical studies. Long-term real-world data help to confirm the durability of this response.

Methods: This non-interventional, longitudinal study used data from the US CF Foundation Patient Registry to describe the annualized rate of change in lung function in people with CF receiving IVA. The IVA-treated cohort included people with CF aged ≥ 6 years who had ≥ 1 CF transmembrane conductance regulator (CFTR)-gating mutation and initiated IVA between 31 January 2012 and 31 December 2018. An age-matched comparator cohort included people with CF heterozygous for the F508del-CFTR mutation and a minimal function mutation (R117H excluded) and had not received CFTR modulator therapy. Baseline characteristics were balanced using standardized mortality ratio (SMR) weights computed from estimated propensity scores. The annualized rate of change in percent predicted forced expiratory volume in 1 s (ppFEV₁) was estimated over 5 years and used to calculate the relative annualized rate of change in lung function in the IVA-treated versus comparator cohorts.

Results: In the 5-year follow-up period, 548 people were in the IVA-treated and 541 in the comparator cohorts after SMR weighting. The annualized rate of change in ppFEV₁ over 5 years was -1.23 (95% CI -1.45, -1.03) and -2.03 (-2.16, -1.90) percentage points in the IVA-treated and comparator cohorts, respectively. There was a 39% reduction (95% CI: 28, 50) in the rate of lung function decline in the IVA-treated versus comparator cohort over 5 years. Findings were generally consistent with those of shorter follow-up periods.

Conclusion: IVA showed a durable clinical benefit by slowing the rate of lung function decline over 5 years. Results support a sustained and consistent impact of IVA on lung function trajectory in people with CF. Word count: 300 (limit: 300 words).

期刊介绍： Aims and Scope Pulmonary Therapy is an international, open access, peer-reviewed (single-blind), and rapid publication journal. The scope of the journal is broad and will consider all scientifically sound research from pre-clinical, clinical (all phases), observational, real-world, and health outcomes research around the use of pulmonary therapies, devices, and surgical techniques. Areas of focus include, but are not limited to: asthma; chronic obstructive pulmonary disease; idiopathic pulmonary fibrosis; pulmonary hypertension; cystic fibrosis; lung cancer; respiratory tract disorders; allergic rhinitis and other respiratory allergies; influenza, pneumococcal infection, respiratory syncytial virus and other respiratory infections; and inhalers and other device therapies. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/series, trial protocols and short communications such as commentaries and editorials. Pulmonary Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. Rapid Publication The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of pulmonary therapies. Open Access All articles published by Pulmonary Therapy are open access. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. Digital Features and Plain Language Summaries Pulmonary Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of an article, authors will be required to pay the mandatory Rapid Service Fee of €4500/ $5100/ £3650. The journal will consider fee discounts and waivers for developing countries and this is decided on a case by case basis. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials, and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case-by-case basis and should be sent to the journal editor. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the manuscript is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
