Abstract
Rheumatoid arthritis, ankylosing spondylitis and psoriatic arthritis are common rheumatic diseases leading to irreversible joint damage and increase in mortality. The introduction of highly effective biologic drugs has resulted in substantial benefit in the treatment of these diseases, but these therapies take a high toll on healthcare systems. The recent availability of biosimilars, biologic drugs which are highly similar to their respective originator products, is changing the treatment landscape allowing substantial reduction in costs and potentially larger access to this therapeutic option. In this scenario switching stable patients from originators to biosimilars may represent a reasonable and cost-saving treatment strategy. The safety and efficacy of non-medical switching have been evaluated in randomized controlled and real-world evidence studies, with conflicting results and the nocebo effect is a well-recognized phenomenon. The aim of this review is to evaluate the evidence in this area trying to delineate which might be the best strategy in routine clinical care.
