THU0224 Renacer study: efficacy and safety assessment of czp therapy in the treatment of 501 patients with rheumatoid arthritis(RA) among spanish population in clinical practice
2018
Background Certolizumab PEGol (CZP) differs from other anti-TNFs in that it is monovalent and it lacks the Fc region found in monoclonal antibodies. CZP is also PEGylated. Its efficacy in patients with rheumatoid arthritis (RA) has been evaluated in previous clinical trials. Objectives The purpose of the current study is to assess effectiveness, safety and survival rate in patients with RA after 12 months of treatment and also within specific subgroups, in clinical practice settings. Methods Observational longitudinal prospective study of RA patients from 40 sites in Spain. Variables (baseline, 3- and 12 month assessment): socio-demographics, smoking status, previous synthetic DMARD (sDMARD) and biological DMARD (bDMARD) use; TJC, SJC, ESR, CRP, DAS28. Response variables EULAR Moderate/Good Response and DAS28 remission and Safety were assessed. Descriptive, comparative and Logistic regression analyses were performed. Kaplan-Meier survival curve was performed. Results A total of 501 patients were included: 78.6% women, mean age 53.6 year (±13.2 SD) and 77% were aged Baseline predictors of response: lower prior number sDMARD; low number prior bDMARD; higher CRP, ESR, TJC, SJC and DAS28 (p Patients CZP survival rates are shown in Figures 1 and 2. Adverse effects from treatment were reported in 65 patients (13%), mostly mild. Conclusions CZP showed benefit in active RA patients, with clear improvement in all clinical parameters, mostly in Reference [1] Torrente-Segarra V, et al; (RENACER StudyGroup).
