Role of biosimilar introduction on insulin glargine prices: a retrospective analysis in 28 European countries.
Article in BMJ open, 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
objectiveQuantify insulin glargine prices following the market introduction of biosimilars. Examine price levels and price changes for originator and biosimilars, by country.
methodsRetrospective quantitative analysis using insulin glargine pricing data, both of the originator product and its biosimilars. Segmented regression analysis using a dual-model approach: pooled and country-specific.
setting28 European countries using data from the European Medicine Price Database for the period 2013-2023.
main outcome measuresPrice variations between countries were analysed to assess trends and correlations before and after biosimilar market entry.
resultsIn the 28 countries studied, cost of insulin glargine underwent a median 21.6% decrease overall in the last decade (p<0.001). In 2022, the median price was €9.0 for the originator (first to market) Lantus (IQR €8.1-€10.4), €8.9 for the biosimilar Abasaglar (IQR €7.6-€10.1) and €7.0 for the biosimilar Semglee (median €7.0; IQR €6.8-€7.5). The originator price was higher than biosimilars (p=0.009). Biosimilar market entry was associated with an overall significant price reduction of the originator, both immediately after entry (p<0.001) and in the long-term postentry (p<0.001). No significant correlation was observed between the price of insulin and the countries' economic indicators.
conclusionThis is the first study to show the price trend of insulin glargine and its correlation with the introduction of biosimilars, in Europe. A significant price reduction of the originator was observed after biosimilars entered the market. The median cost of biosimilars was lower than the originator, although with substantial differences between individual countries and producers.
