The European Perspective and History on Biosimilars for the Treatment of Inflammatory Bowel Diseases.

ABSTRACT: With the expiration of biologics' patents, biosimilars entered the market as a promising opportunity to reduce health-care costs in the field of inflammatory bowel diseases. Although biosimilars were initially poorly accepted, the growing evidence about their efficacy and safety has changed this situation, resulting in their widespread use. However, there is still an unmet need of improving patients' education about biosimilars to minimize nocebo responses and to accept nonmedical switching. Looking to the future, the use of recently authorized adalimumab biosimilars and the first attempts of adopting different strategies of switching (eg, cross-, multiple-) will fill some residual knowledge gaps.

Project description:BackgroundClinicians are required to assimilate, critically evaluate, and extrapolate information to support appropriate use of biosimilars across indications.ObjectivesThe objective of this study was to systematically collate all published data in order to assess the weight (quantity and quality) of available evidence for each molecule and inform and support healthcare decision-making in chronic inflammatory diseases.MethodsMEDLINE®, EMBASE®, and ISI Web of Science® were searched to September 2015. Selected conference proceedings were searched from 2012 to July 2015. Studies disclosing biosimilars with unique identifiers were categorized by originator, study type, and indication. Risk of bias assessments were performed. Intended copies were differentiated as commercially available agents without evidence of rigorous comparative biosimilarity evaluations.ResultsProposed biosimilars for adalimumab, etanercept, infliximab, and rituximab are reported in the published literature. Across indications, approved biosimilars infliximab CT-P13, SB2, and etanercept SB4 have published studies involving the largest number of patients or healthy subjects (n = 1405, 743, and 734, respectively), mostly in rheumatoid arthritis. At data cut-off, only CT-P13 had published data in ankylosing spondylitis (n = 250; randomized control trial) and ulcerative colitis/Crohn's disease (n = 336; observational studies). Published data were not available for ongoing studies in psoriasis patients. Four intended copies were identified in published studies (total: n = 1430; n = 1372 in observational studies). Thematic analysis of non-empirical publications showed that indication extrapolation remains an issue, particularly for gastroenterologists.ConclusionsWhile most agents display a moderate to high degree of similarity to their originator in the published studies identified, large discrepancies persist in the overall amount and type of data available in the public domain. Significant gaps exist particularly for intended copies, reinforcing the need to maintain a clear differentiation between these molecules and true biosimilars.
