Abstract
Introduction: Clinical trials have demonstrated prolonged survival associated with niraparib first-line maintenance (1LM) therapy, compared with placebo, for patients with ovarian cancer (OC). However, data are limited on real-world 1LM niraparib monotherapy use, particularly as switch 1LM, following first-line (1L) combination chemotherapy plus bevacizumab. This real-world study aimed to describe patient demographics, clinical characteristics, and clinical outcomes of patients with OC receiving 1LM niraparib monotherapy following 1L combination chemotherapy plus bevacizumab.
Methods: This retrospective observational study used data from a US-based nationwide database of deidentified, electronic health record-derived data. Patients diagnosed with OC during the study period (1 January 2011-30 November 2022, inclusive) were eligible if they received 1L chemotherapy plus bevacizumab treatment followed by 1LM niraparib monotherapy, initiated between 1 January 2017 (inclusive) and 2 September 2022. Patients were followed from index date (initiation of niraparib 1LM) until the first occurrence of death, end of follow-up, or end of study. Clinical outcomes were time to treatment discontinuation (TTD) and time to next treatment (TTNT). Kaplan-Meier curves were used to estimate TTD, TTNT, and 95% confidence intervals (CIs).
Results: Among 93 patients selected, median age at index was 67 years (interquartile range [IQR] 60-72 years). Most patients had BRCA wild-type/homologous recombination (HR)-proficient or BRCA wild-type/HR unknown disease (75.3%). In all, 18 (19.4%) patients had HR-deficient disease. Five (5.4%) patients had unknown test results for both BRCA and HR deficiency status. Median follow-up time was 16.3 months (IQR 8.7-25.4 months), and median time from end of 1L therapy to 1LM initiation was 35.0 days (IQR 25.0-53.9 days). Median TTD was 9.3 months (95% CI 6.1-11.3 months). Median TTNT was 12.9 months (95% CI 11.5-19.0 months).
Conclusions: This real-world study provided insights into switch maintenance with 1LM niraparib monotherapy, which may be a viable treatment option for patients with advanced OC.

Aims and Scope
Oncology and Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality pre-clinical, clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Oncology 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.
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 clinical 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 and plain language summaries
Oncology 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.
Please see here for further information on preprint sharing: https://www.springer.com/gp/authors-editors/journal-author/journal-author-helpdesk/submission/1302#c16721550
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.
