BackgroundThe efficacy and safety of certolizumab pegol (CZP) in moderate-to-severe Crohn's disease were demonstrated in two 26-week double-blind studies (PRECiSE 1 & 2). AimTo report the safety and efficacy outcomes of long-term, CZP therapy from PRECiSE 3, in which patients received treatment up to 7years treatment. MethodsPatients completing PRECiSE 1 or 2 were eligible to enter PRECiSE 3 in which they received CZP 400mg, open-label, every 4weeks (without additional induction therapy) for up to 7years, for up to 91 doses from study start. Safety (adverse events, including infections and malignancies) and efficacy (Harvey-Bradshaw Index, faecal calprotectin, C-reactive protein) were prospectively monitored. Remission was analysed using observed cases, last observation carried forward imputation and nonresponder imputation. ResultsA total of 595 patients entered the study; 117 (20%) completed 7years. Discontinuation rates were 29.2%, 13.6%, 16.1%, 7.9%, 5.0%, 4.5% and 3.9% (years 1-7 respectively). During 1920 patient-years of exposure to CZP, no new safety signals were observed. Incidence rates (new cases/100 patient-years) for serious infections and malignant neoplasms were 4.37 and 1.06 respectively. No lymphoproliferative malignancies were reported. Clinical remission rates were 68% at each year (observed cases); rates by last observation carried forward and nonresponder imputation were 58% and 45% at year 1, 56% and 26% at year 3 and 55% and 13% at year 7 respectively. ConclusionCertolizumab pegol was well tolerated in the long-term treatment of Crohn's disease, with sustained remission in some patients continuing in the study for up to 7years.
