Methotrexate reduces immunogenicity in adalimumab treated rheumatoid arthritis patients in a dose dependent manner

Immunogenicity of adalimumab could impair important treatment outcome parameters in patients with rheumatoid arthritis (RA). Patients who developed antiadalimumab antibodies (AAA) during a 3 year time period achieved less often minimal disease activity or remission and treatment failure occurred more often compared with patients without AAA.1 There were remarkable baseline differences: patients developing AAA had more long-standing, severe...
