Barcelona, Spain, 14 June 2007 - 7:00 am CET - New pivotal data (RAPID 1 and RAPID 2) presented at the Annual European Congress of Rheumatology (EULAR) show that CIMZIA(TM) (certolizumab pegol), the first PEGylated, Fc-free anti-TNF, combined with methotrexate therapy has a rapid and significant effect in reducing the signs and symptoms of active rheumatoid arthritis (RA) compared with methotrexate alone. Data from a third study, the 011 trial, presented at the conference also showed that CIMZIA(TM) given every four weeks as monotherapy is significantly more efficacious than placebo in the treatment of patients with active RA who had previously failed disease-modifying anti-rheumatic drug (DMARD) therapy.
