Abatacept, which suppresses T cells by binding with CD80/CD86 of antigen-presenting cells, was newly developed and approved in Japan for treatment of rheumatoid arthritis (RA) in September 2010. Some clinical trials implemented in Western countries and Japan suggested that the efficacy and safety of abatacept were equivalent to other existing biologic agents and the incidence of serious adverse events was relatively low. However, evidence of effectiveness and safety of abatacept in Japanese patients in the real world has not sufficiently proved yet and remains to be established. Therefore, we planned this study to clarify effectiveness and safety of abatacept in Japanese patients with RA and to find predictive factors for effectiveness. In addition, we also analyze comprehensive gene expression information from blood samples obtained at the initiation of and 6 months after the therapy with clinical information to find candidate genes associated with the effectiveness and safety of abatacept.
Efficacy
Confirmatory
Pragmatic
Not applicable
Effectiveness of abatacept: EULAR response rate at month 6; ACR/EULAR remission rate at month 6
Safety of abatacept: incidence of serious adverse drug reactions; incidence of serious infection during 1 year
Effectiveness of abatacept: changes of joint scores, acute inflammatory response, and visual analogue scales over time; changes of Total Sharp Score at year 1; percentages of patients with delta Total Sharp Score <0.5; changes of physical function over time (HAQ, EQ-5D).
Safety of abatacept: incidence of adverse events and adverse drug reactions during 1 year; incidence of infection during 1 year
Other outcomes: analysis of mRNA expression with clinical information
