Abstract
Objective. To report on the 5-year efficacy and safety results of the AMBITION (Actemra versus Methotrexate double-Blind Investigative Trial In mONotherapy) monotherapy study (ClinicalTrials.gov: NCT00109408, NCT00720798).
Methods. Patients with rheumatoid arthritis for whom biologics had not failed or who did not discontinue methotrexate because of lack of efficacy or tolerability were followed up for 5 years to assess the efficacy and serious adverse events (SAE) of tocilizumab (TCZ) monotherapy.
Results. Longterm efficacy results showed that efficacy was maintained or improved for up to 264 weeks in patients receiving TCZ monotherapy. Serious infection was the most frequent SAE; no new safety signals were reported.
Conclusion. Longterm monotherapy with TCZ demonstrated continuing efficacy and safety.
