Real-world incidence of and risk factors for abemaciclib-induced interstitial lung disease in Japan: a nested case-control study of abemaciclib-induced interstitial lung disease (NOSIDE).
Article in Breast cancer (Tokyo, Japan), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe exact incidence of and risk factors for interstitial lung disease (ILD), a serious side effect of abemaciclib, remain unknown in real-world settings. We examined the incidence of and risk factors for abemaciclib-induced ILD in patients with advanced breast cancer (ABC) in Japan. PATIENTS AND
methodsRetrospective clinical information was collected from charts of patients with ABC who had started abemaciclib treatment at 77 participating institutions between November 30, 2018 and December 31, 2019. The clinical information of patients who developed ILD (including suspected cases) were reviewed by an independent committee of extramural experts to adjudicate abemaciclib-induced ILD. We performed a nested case-control study for efficient identification of ILD risk factors and conducted multivariate Cox regression analysis to identify independent predictors of ILD.
resultsAmong patients taking abemaciclib, the incidence of abemaciclib-induced ILD was 5.0% (n = 59/1189), and the mortality rate was 0.7% (n = 8). The timing of ILD onset varied but occurred most frequently within 180 days of beginning abemaciclib treatment (64.4%). The incidence of abemaciclib-induced ILD was significantly associated with Eastern Cooperative Oncology Group performance status (ECOG PS) ≥ 2 [hazard ratio (HR) 5.03; 95% confidence interval (CI) 2.26-11.11] or a past medical history of interstitial pneumonia (IP) (HR 6.49; 95% CI 3.09-13.70).
conclusionsIn this study, we have for the first time determined the real-world incidence of and risk factors for abemaciclib-induced ILD in Japan. Although abemaciclib-induced ILD is serious in real-world settings, careful patient selection and close monitoring of those with poor ECOG PS and/or a history of IP may minimize ILD risk. This study was registered on the UMIN registry (Date: May 11, 2020/ ID: UMIN000040357).
