Poster abstracts events (AEs) in Period A were reported by 55.6% PBO vs 56.9% ADA (with PsA: 56.3% PBO vs 56.7% ADA; without PsA: 55.3% PBO vs 57.0% ADA without PsA); serious AEs by 4.6% PBO vs 7.3% ADA (with PsA: 9.4% PBO vs 10.0% ADA; without PsA: 2.6% PBO vs 6.3% ADA). Conclusions: The results demonstrated that in this population, ADA was more effective than PBO for the treatment of fingernail Ps, and significantly improved signs and symptoms, both overall and regardless of the presence or abscense of PsA; no new safety risks were identified with ADA eow treatment for 26 weeks.

[1,2] Objectives: To assess the efficacy of CZP to 48 weeks across patient (pt) demographic and baseline disease characteristic sub- groups in phase 3 trials. Methods: In this prespecified, pooled subgroup analysis, data were pooled from CIMPASI-1 (NCT02326298) and CIMPASI-2 (NCT02326272), ongoing phase 3 trials in adults with moderate to severe PSO ≥6 months (psoriasis area and severity index [PASI] ≥12, affected body surface area [BSA] ≥10%, physician’s global assessment [PGA] ≥3/5). Pts were randomized 2:2:1 to CZP 400 mg every 2 weeks (Q2W), 200 mg Q2W (400 mg loading dose at Weeks 0/2/4), or placebo (PBO). At Week 16, PASI 50 responders receiving CZP continued the same dose through the maintenance period to Week 48. PASI 50 nonresponders at Weeks 32/40/48 were classed as nonresponders at subsequent time points. Subgroups included age, weight, body mass index (BMI), baseline PASI, BSA and PSO duration. PASI 75, PGA 0/1, and PASI 90 responder rates were summarized at Week 16 using a logistic regression model with multiple imputation (overall population) and descriptively at Week 48 based on nonresponse imputation (subgroups). Results: 175/186/100 pts received CZP 400 mg Q2W/CZP 200 mg Q2W/PBO. Efficacy was observed across all subgroups for both CZP 400 mg Q2W and 200 mg Q2W, with higher Week 48 PASI 75 responder rates in CZP 400 mg Q2W vs CZP 200 mg Q2W treated pts (Table). Similar trends were observed for PGA 0/1 and PASI 90. Conclusions: Treatment with either dose of CZP resulted in clinically meaningful improvements in signs and symptoms of PSO at Week 16 maintained at Week 48. Similar to the overall population, PASI 75, PGA 0/1, and PASI 90 responder rates were greater for CZP 400 mg Q2W versus 200 mg Q2W across most subgroups at Week 48. References: 1. Reich K (2017).

Biologic treatment have been very successful in controlling mode- rate to severe psoriasis, however they are quite expensive and not all treatments work for all patients. This study looks to understand the demographics, treatment patterns, treatment failures, number of therapies and time to switching. A cohort of 459 patients treated with biologics was examined Objectives: 1. To understand the demographics, treatment patterns, treatment failures, number of therapies and time to switching. 2. To decipher patterns in biologic use in order to prescribe more efficiently and optimize health care resources. Methods: This was a retrospective cohort of all patients exposed to biologic or PD-4 inhibitors within a single Dermatologist’s private practice. A simple summary of patient demographics including gender, treatment patterns, reasons and length of time before discontinuation was compiled. Reasons for discontinuation included lack of efficacy (primary or secondary), adverse events (AEs), patient choice or other. Results: There were 189 females (41.2%) and 270 males (58.8%) with 914 incidences of biologic or PD-4 inhibitor treatment. The mean age was 53.48 ± 12.6 and the mean treatment duration was 37.3 months ± 39.5 (approx. 3000 treatment years). 39.2% of patients (180) remained on the first biologic (range 0.5 to 15 years). The mean number of therapies was 1.99 (range 1–8), but increased to 2.63 if patients were not biologic naive. More male patients stayed on their first biologic (74.2% in ustekinumab-treated patients and in the Apremilast group 32.3%). Reasons for discontinuation: AEs (14.69%) and non-response (30%); highest rates were in etanercept (78.0%), and infliximab (75.4%); lowest rates was in etanercept 12.8% (14 of 109 patients), highest in infliximab 34.9%, (44 of 126 patients. Conclusions: The most common cause for discontinuation of biologics was an AE and non-responsiveness (45.69%). Women Acta Derm Venereol 2018
