Poster presented at the 36th Fall Clinical Dermatology Conference | Las Vegas, NV | October 12-15, 2017 Certolizumab Pegol for the Treatment of Chronic Plaque Psoriasis: DLQI and WPAI Patient-Reported Outcomes From an Ongoing Phase 3, Multicenter, Randomized, Active- and Placebo-Controlled Study (CIMPACT) Vincent Piguet,1 Andrew Blauvelt,2 Daniel Burge,3 Luke Peterson,4 Janice Drew,3 Robert Rolleri,4 Jolanta Węgłowska5 1Cardiff University and University Hospital of Wales, Cardiff, UK; 2Oregon Medical Research Center, Portland, OR; 3Dermira, Inc., Menlo Park, CA; 4UCB BioSciences, Inc., Raleigh, NC; 5Niepubliczny Zakład Opieki Zdrowotnej multiMedica, Wrocław, Poland INTRODUCTION • Psoriasis affects ~3% of adults in the US1,2 and ~2-6% of adults in Europe3; onset can begin at any age, though most patients develop the disease in the third decade of life4 • Psoriasis can have a significant negative impact on the physical, emotional, psychosocial, and economic well‑being of affected patients5,6 – In the US, over 80% of psoriasis patients report that the disease negatively affects their emotional state and their enjoyment of life6 – Over 90% of unemployed US psoriasis patients report not working solely due to psoriasis or psoriatic arthritis, and almost half of working psoriasis patients regularly miss work due to the disease6 – Quality of life instruments for psoriasis have been useful to assess the impact of psoriasis on patients lives and well‑being7,8 • Certolizumab pegol (CZP) is the only PEGylated, Fc-free, anti-TNF biologic and is currently under investigation for the treatment of moderate-to-severe chronic plaque psoriasis • Previously presented data through Week 16 of 3 ongoing, randomized, double-blind, placebo‑controlled trials have demonstrated clinically meaningful efficacy and a safety profile consistent with anti‑TNF therapy9,10 • CIMPACT (NCT02346240) is designed to assess the efficacy and safety of treatment with CZP compared with placebo and etanercept (ETN) in adult patients with moderate-to-severe chronic plaque psoriasis; results of patient-reported outcomes through Week 16 for all patients and results through Week 48 for patients initially treated with CZP are presented here METHODS Study Design • CIMPACT is an ongoing phase 3, randomized, multinational, parallel-group, placebo- and active-controlled trial • Patients were randomized 3:3:1:3 to CZP 400 mg every 2 weeks (Q2W), CZP 200 mg Q2W (after an initial loading dose of 400 mg at Weeks 0, 2 and 4), or placebo Q2W for 16 weeks or ETN twice weekly for 12 weeks (Figure 1) • At Week 16, CZP‑ and ETN‑treated PASI 75 responders were re‑randomized and continued for 32 weeks of maintenance treatment: – From CZP 400 mg Q2W to 400 mg Q2W, 200 mg Q2W, or placebo Q2W – From CZP 200 mg Q2W to 400 mg every 4 weeks (Q4W), 200 mg Q2W, or placebo Q2W – From ETN to CZP 200 mg Q2W (after loading dose) or placebo Q2W • At Week 16, placebo‑treated PASI 75 responders continued placebo Q2W for 32 weeks of maintenance treatment • At Week 16, PASI 75 nonresponders entered an Escape Arm for treatment with CZP 400 mg Q2W Figure 1.

Absenteeism (work time missed) 2. Presenteeism (reduced on‑the‑job effectiveness) 3. Work productivity loss (overall work impairment) 4. Activity impairment (impairment performing regular daily activities) – Questions related to the first 3 domains were to be completed only by patients who were employed at the time of the assessment; questions related to the last domain were to be completed by all patients – WPAI domain scores are impairment percentages; higher numbers indicate greater impairment and less productivity • Assessments at Weeks 16 and 48 – Change from Baseline (CfB) in DLQI – DLQI minimal clinically important difference (MCID; ≥4‑point reduction7) responder rate – DLQI 0/1 (absolute score ≤1) responder rate – CfB in WPAI Statistical Analysis • Efficacy analyses at Week 16 were performed on the Randomized Set (all randomized patients) • Efficacy analyses at Week 48 were performed on the Maintenance Set (patients completing the Week 16 visit with ≥1 efficacy measurement during the Maintenance Period) • Inferential statistics for CfB in DLQI and WPAI at Week 16 were based on analysis of covariance (ANCOVA) • Mean CfB values are presented for continuous variables, and percentages are presented for responder variables • Last observation carried forward (LOCF) imputation was used to impute data for CfB in DLQI (Week 16 and 48) and WPAI (Week 16) • Nonresponse imputation was used for DLQI MCID and DLQI 0/1 analyses • Week 48 WPAI data was assessed based on observed cases RESULTS Patient Disposition, Demographics, and Baseline Characteristics • A total of 167, 165, and 57 patients were randomized to CZP 400 mg Q2W, CZP 200 mg Q2W, or placebo, respectively (Figure 2) • Patient demographics and Baseline characteristics were similar between groups (Table 1) Figure 2.
