Abstract
Introduction: Real-world data on ixekizumab utilization in axial spondyloarthritis (axSpA) are limited. We evaluated ixekizumab treatment patterns and health care resource utilization (HCRU) in patients with axSpA using United States Merative L.P. MarketScan® Claims Databases.
Methods: This retrospective cohort study included adults with axSpA who initiated ixekizumab during the index period (September 2019-December 2021). Index date was the date of the first ixekizumab claim. All patients had continuous medical and pharmacy enrollment during the 12-month pre-index and follow-up periods. Descriptive statistics were used to assess patient demographics (index date); clinical characteristics (pre-index period); treatment patterns (12-month follow-up period); and HCRU (pre-index and 12-month follow-up periods).
Results: The study included 177 patients (mean age 45.8 years; females 54.8%) with axSpA who initiated ixekizumab. Overall, 79.1% of patients reported prior biologic use; of these, 70.7% received tumor necrosis factor-alpha inhibitors (TNFi) and 49% received secukinumab. The mean (standard deviation [SD]) Charlson Comorbidity Index score was 1.1 (1.3) and ~ 27% of patients reported ≥2 comorbidities. The median (inter-quartile range [IQR]) number of ixekizumab prescription refills was 7 (4-11). The mean (SD) Proportion of Days Covered (PDC) for ixekizumab was 0.6 (0.3) and adherence (PDC ≥80%) was 34.5% (N = 61). Overall, 26.6% (N = 47) of patients switched to a non-index medication and 54.2% (N = 96) of patients discontinued ixekizumab. Among the patients who discontinued ixekizumab (N = 96), 19.8% (N = 19) restarted ixekizumab and 49.0% (N = 47) switched to a non-index medication. The median (IQR) ixekizumab persistence was 268 (120-366) days. Mean axSpA-related outpatient, inpatient, and emergency room visits were similar between the pre-index and follow-up periods. Treatment patterns were largely similar between biologic-experienced patients (N = 140; 79.1%) and the overall population.
Conclusions: Despite high comorbidity burden and majority of the patients being biologic-experienced, patients initiating ixekizumab for axSpA showed favorable persistence profiles during the 12-month follow-up period.
轴性脊柱关节炎患者的伊昔单抗治疗模式与医疗资源利用：美国索赔数据库回顾性研究》。
导言：轴性脊柱关节炎（axSpA）患者使用ixekizumab的实际数据非常有限。我们利用美国 Merative L.P. MarketScan® 索偿数据库评估了 axSpA 患者的 ixekizumab 治疗模式和医疗资源利用率（HCRU）：这项回顾性队列研究纳入了在指数期（2019 年 9 月至 2021 年 12 月）开始使用 ixekizumab 的 axSpA 成人患者。指数日期为首次报销 ixekizumab 的日期。所有患者均在 12 个月的指数前和随访期间连续进行了医疗和药学注册。研究采用描述性统计方法评估患者人口统计学特征（指数日期）、临床特征（指数前）、治疗模式（12 个月随访期）和 HCRU（指数前和 12 个月随访期）：研究共纳入了 177 名开始使用 ixekizumab 的 axSpA 患者（平均年龄 45.8 岁，女性占 54.8%）。总体而言，79.1%的患者报告曾使用过生物制剂；其中70.7%曾使用肿瘤坏死因子-α抑制剂（TNFi），49%曾使用secukinumab。Charlson合并症指数平均值（标准差[SD]）为1.1（1.3），约27%的患者合并症≥2种。ixekizumab处方重配次数的中位数（四分位间距 [IQR]）为7（4-11）次。ixekizumab的平均（标度）覆盖天数（PDC）为0.6（0.3），依从性（PDC ≥80%）为34.5%（N = 61）。总体而言，26.6%的患者（N = 47）改用了非指标药物，54.2%的患者（N = 96）停用了ixekizumab。在停用 ixekizumab 的患者中（N = 96），19.8%（N = 19）重新开始使用 ixekizumab，49.0%（N = 47）改用非指标药物。ixekizumab持续治疗的中位数（IQR）为268（120-366）天。索引前和随访期间与 axSpA 相关的平均门诊、住院和急诊就诊次数相似。有生物治疗经验的患者（N = 140；79.1%）与总体人群的治疗模式基本相似：尽管合并症负担很重，而且大多数患者都有生物治疗经验，但开始使用ixekizumab治疗axSpA的患者在12个月的随访期间表现出了良好的持续性。

期刊介绍：
Aims and Scope
Rheumatology and Therapy is an international, open access, peer reviewed, rapid publication journal dedicated to the publication of high-quality clinical (all phases), observational, real-world and health outcomes research around the discovery, development, and use of rheumatologic therapies. Studies relating to diagnosis, pharmacoeconomics, public health, quality of life, and patient care, management, and education are also welcomed.
Areas of focus include, but are not limited to, rheumatoid arthritis, gout, gouty arthritis, psoriatic arthritis, osteoarthritis, juvenile idiopathic/rheumatoid arthritis, systemic lupus erythematosus, axial spondyloarthritis, Pompe’s disease, inflammatory joint conditions, musculoskeletal conditions, systemic sclerosis, and fibromyalgia.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, case reports, trial protocols, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Rheumatology and 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 all scientifically and ethically sound research.
Ethics and Disclosures
The journal is a member of the Committee on Publication Ethics (COPE) and subscribes to its principles on how to deal with acts of misconduct thereby committing to investigate allegations of misconduct in order to ensure the integrity of research. Content in this journal is peer-reviewed (Single-blind). For more information on our publishing ethics policies, please see here: https://www.springer.com/gp/editorial-policies
Rapid Publication
The journal’s rapid publication timelines aim for a peer review decision within 2 weeks of submission. If an article is accepted it will be published online 3-4 weeks from acceptance. These rapid timelines are achieved through the combination of a dedicated in-house editorial team, who closely manage article workflow, and an extensive Editorial and Advisory Board who assist with rapid 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 and efficient communication of the latest research and reviews, allowing the advancement of rheumatologic therapies.
Personal Service
The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning that authors will always have a personal point of 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. We also encourage pre-submission enquiries and are always happy to provide a confidential assessment of manuscripts.
Digital Features
Rheumatology and 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’.

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 the journal. 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.

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. 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, and authors are welcome to make rebuttals against individual reviewer comments if appropriate.
Considering the time and effort required for a detailed peer review we reward our regular reviewers with the opportunity to publish without publication fees (pending peer review) for every three reviews completed per calendar year.
