We present the outcomes of a ­service evaluation of switching rheumatic patients established on originator etanercept (Enbrel) to biosimilar Benepali, using a managed switching programme funded through a novel fixed price incentivisation model.Methods Evaluation outcomes included savings in drug acquisition costs, patient-reported side effects, adverse events, patient outcomes and patient experience.Results A total of 154 patients on Enbrel were identified for switching. A total of 113 patients (43 had rheumatoid arthritis, 43 had axial spondyloarthritis and 27 had psoriatic arthritis) were switched from originator etanercept to Benepali from August 2016 to March 2017. The Royal Berkshire NHS Foundation Trust had the highest percentage of switches in the Thames Valley in this period. There was no increased incidence of side effects before and after switch. Drug acquisition costs were decreased by £95,000 with an overall reduction in prescribing costs of £186,000 for the local health economy.Conclusions A managed switching programme from originator etanercept to biosimilar Benepali, using a novel fixed price model, delivers significant cost savings and investment in clinical services while maintaining similar patient-reported outcomes and good patient experience.
