Budget Impact Analysis of the Introduction of a Trastuzumab Biosimilar for HER2-Positive Breast Cancer in China.
Article in Clinical drug investigation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 of them syntheses that pooled it.
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
BACKGROUND AND
objectiveBiosimilars provide the possibility to reduce the high expenditure on biologic drugs and expand access to effective but less expensive treatments. Biosimilars of trastuzumab showed significant cost savings from the payer's perspective in the USA and Europe. After 2020, with the first approval of a trastuzumab biosimilar in China, it became feasible for biosimilar switching for trastuzumab. However, the economic impact of switching to a trastuzumab biosimilar was not evaluated. A budget impact model was constructed from a payer's perspective of China to demonstrate the economic impact of the introduction of a biosimilar trastuzumab in the treatment of human epidermal growth factor receptor 2-positive breast cancer.
methodsThis budget impact model was based on disease incidence to estimate the net budget impact using epidemiological data from the literature, financial reports from manufacturers on the market shares of originator trastuzumab (Herceptin
resultsAnalyses of the base-case and scenario results implied that adoption of a trastuzumab biosimilar would lead to an expenditure decrease. The average total cost savings over 5 years was estimated to be US$46,651,348, with a range from $10,306,611 in year 1 to $60,821,822 in year 5. The cost savings could benefit an additional 654-3858 patients with breast cancer. If utilizing costs from real-world practice, the introduction of a trastuzumab biosimilar could help an additional 2237-13,203 patients get access to human epidermal growth factor receptor 2-positive targeted therapy. When volume-based procurement was carried out after year 4, $672,366,180 could be saved annually.
conclusionsThis budget impact analysis emphasized the positive effects of adopting a trastuzumab biosimilar in the healthcare system of China. However, cost savings still have a large potential to decrease by regulating pricing and by the procurement policy of biosimilars.
