Comparing safety information of biosimilars with their originators: a cross-sectional analysis of European risk management plans.
Article in British journal of clinical pharmacology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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
aimsBiosimilars have been available in the European Union (EU) since 2006. However, their uptake in routine care is heterogeneous across countries. The aim of the present study was to compare the safety information of biosimilars and their originators based on the information in the European risk management plan (RMP).
methodsA cross-sectional analysis on publicly available regulatory documents (RMPs and Summaries of Product Characteristics) of biosimilars and corresponding originators up to 1 November 2015 was performed. The safety concerns were extracted and merged into general safety concerns, and clinical relevance was assessed. The frequency of safety concerns and the representation of these safety concerns per general safety concern were assessed by either comparing RMPs of biosimilars and originators (if available for both) or comparing RMPs with the Summary of Product Characteristics of the originator.
resultsNineteen biosimilars and six originators were included. Overall, 55 general safety concerns (12 low, 21 medium and 22 highly clinically relevant) were identified. For all active substances, except for infliximab, no or only one difference was found in the listed general safety concerns. Comparison of regulatory documents for infliximab identified three medium clinically relevant general safety concerns more for infliximab biosimilars and two general safety concerns more for its originator.
conclusionBased on publicly available information filed for regulatory purposes, no substantial differences were observed in the reporting of safety information for biosimilars and related originators. A direct comparison between biosimilars and related originators through formal postmarketing studies is needed to evaluate specific safety issues emerging during the products' life cycle.
