Background:
Certolizumab pegol (CZP) is an Fc-free, PEGylated anti-tumor necrosis factor biologic.

Objectives:
To report three-year outcomes from the CIMPACT (NCT02346240) phase 3, CZP in moderate to severe plaque psoriasis, randomized controlled trial.

Methods:
Adults were randomized 3:3:3:1 to CZP 200 mg every other week (Q2W), CZP 400 mg Q2W, etanercept biweekly, or placebo. At Week 16, CZP- and etanercept-treated PASI 75 responders were re-randomized to CZP 200 mg Q2W, CZP 400 mg Q4W, CZP 400 mg Q2W, or placebo for maintenance treatment; PASI 75 non-responders entered an open-label escape CZP 400 mg Q2W arm. Patients entering the open-label extension (OLE; Weeks 48-144) from blinded treatment received CZP 200 mg Q2W.

Results:
Double-blinded results have been reported previously. 261 patients received 200 mg Q2W upon OLE entry. PASI 75 response was maintained in patients continuing 200 mg Q2W treatment through Weeks 16-144 (Week 144: 96.2%). In patients dosed down at Week 48 (double-blinded 400 to 200 mg Q2W), PASI 75 decreased (Week 48: 98.7%; Week 144: 85.9%). In patients who received placebo through Weeks 16-48, PASI 75 response decreased (Week 48: 60.4%), then increased following Week 48 switch to 200 mg Q2W (Week 144: 95.1%). 48 and 36 patients initially randomized to 200 and 400 mg Q2W, respectively, were Week 16 PASI 75 non-responders and entered the escape arm; at Week 144, 71.8% and 78.2% achieved PASI 75. No new safety signals were identified.

Conclusions:
Response to CZP was durable over three years; no new safety signals were identified.
