Safety and efficacy of certolizumab pegol in a real-life cohort of patients with psoriasis and psoriatic arthritis.

The aim of this observational study was to assess safety and efficacy of certolizumab pegol (CZP) in a real-life cohort of patients affected by psoriasis (PsO) and psoriatic arthritis (PsA), who had an inadequate response to previous systemic immunosuppressive treatments, with a follow-up of 24 weeks. Twelve patients with PsO and PsA, referring to our Dermatology/Rheumatology combined outpatient clinic, were enrolled. Primary endpoints were safety and efficacy of CZP, defined as statistically significant improvement of DAPSA, clinical DAPSA and PASI. Secondary endpoints validated clinical and laboratory measures and patient-reported outcomes. CZP injections were well-tolerated. We observed a rapid and significant improvement in all primary endpoints, in the 24-week treatment period of the study. We described positive effects of CZP in several domains, including joint and skin involvement, pain, patient and physician global assessment, physical function, and health-related quality of life. CZP was effective and safe in patients who were either naïve or previously unresponsive to other anti-TNFα. No difference was found in terms of efficacy and safety between patients treated with CZP monotherapy and patients in combination therapy with methotrexate. CZP was safe and effective in a real-life cohort of patients affected by PsO and PsA, who have had an inadequate response to previous systemic treatments.
