Immunogenicity, efficacy and adverse events of adalimumab in RA patients.

To assess the immunogenicity of adalimumab, a human anti-TNF-alpha mAb, we evaluated the formation of antibodies to adalimumab, efficacy and adverse events among 15 patients with highly active rheumatoid arthritis. Four patients were treated with adalimumab as monotherapy, and 11 patients with concomitant DMARDs. Disease activity was measured by DAS28.
