Summary of Research: Effects of Adalimumab-adbm Versus Adalimumab Reference Product on Patient-Reported Outcomes in Rheumatoid Arthritis: Results from VOLTAIRE-RA

This Summary of Research overviews the results of a study that looked at patient-reported outcomes in the VOLTAIRE-RA trial (NCT02137226), originally published in Rheumatology and Therapy. A biosimilar is a biologic medicine made to be very similar to the original biologic medicine (also known as the reference product). The VOLTAIRE-RA trial compared the efficacy and safety of an adalimumab biosimilar (Cyltezo (R), adalimumab-admb) with the adalimumab reference product, Humira (R), in people with rheumatoid arthritis. As part of the VOLTAIRE-RA study, participants took either adalimumab-adbm or adalimumab reference product for 24 weeks. Patient-reported outcomes were captured after 12 weeks and after 24 weeks of treatment to assess the effects of treatment on each participant's health-related quality of life. People with rheumatoid arthritis who were given adalimumab-adbm or adalimumab reference product experienced similar clinically meaningful improvements in their health-related quality of life after 12 weeks of treatment. A high proportion of people in this trial who were given adalimumab-adbm or adalimumab reference product reported greater improvement versus a reference US population matched by age and sex. This is notable, as it represents a treatment goal that was difficult to achieve in earlier rheumatoid arthritis trials of non-biologic treatments.
