Certolizumab Pegol for the Treatment of Plaque Psoriasis in Routine Clinical Practice: One-Year Results from the CIMREAL Study.

ABSTRACT:

Introduction

Certolizumab pegol (CZP) is an anti-tumor necrosis factor alpha (TNFα) approved for the treatment of moderate to severe plaque psoriasis (PSO). However, data on its real-world use is currently limited. The objective of this study was to describe the 1-year real-world effectiveness of CZP, its impact on health-related quality of life (HRQoL), and safety outcomes in patients with moderate to severe PSO in multi-country settings.

Methods

CIMREAL, a prospective, noninterventional study, was conducted across Europe and Canada from August 2019 to December 2022. Patients were followed for 1-year, receiving CZP 400 mg initial doses at weeks 0, 2, and 4, followed by CZP 200 mg every 2 weeks (Q2W) or CZP 400 mg Q2W maintenance dosing. Effectiveness was assessed using the Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI). Safety was also evaluated.

Results

Overall, 399 patients with moderate to severe PSO were included. Of these, 93.7% (374/399) and 77.9% (311/399) completed months 3 and 12, respectively. Mean age (± standard deviation) was 42.9 ± 13.5 years and body mass index was 28.5 ± 6.8 kg/m², with the majority of patients being female (68.2%). At 12 months, CZP showed substantial effectiveness, achieving PASI 75 and PASI 90 response rates (≥ 75% and ≥ 90% improvement from baseline, respectively) of 77% and 56.5%, respectively. Patients with PASI score of ≤ 3 and ≤ 2 experienced improvement from 3 months (49.8% and 41.1%, respectively) to 12 months (82.0% and 75.3%, respectively). HRQoL considerably improved, with mean DLQI scores decreasing from 12.4 to 2.3 after 12 months of treatment, and the proportion of patients with DLQI 0/1 increased from 28.6% at 3 months to 59.4% at 12 months. The 1-year probability of persistence was approximately 85%. Overall, 30.6% of the patients experienced any adverse events and 9.3% had serious adverse events.

Conclusion

In routine clinical practice, CZP exhibited consistent effectiveness, positively impacting both skin psoriasis activity and HRQoL. The 1-year persistence of CZP was high, and no new safety signals were identified.

Project description:IntroductionCertolizumab pegol (CZP), the Fc-free, PEGylated anti-tumor necrosis factor, is approved for the treatment of moderate to severe plaque psoriasis (PSO) in Western countries and in Japan, among other indications.MethodsWe report results from the first 16 weeks of a 52-week phase 2/3 trial of CZP in Japanese patients with PSO. Patients ≥ 20 years with PSO ≥ 6 months (Psoriasis Area and Severity Index [PASI] ≥ 12, body surface area affected ≥ 10%, and Physician's Global Assessment [PGA] ≥ 3 on a 5-point scale) were randomized 2:2:1 to CZP 400 mg every 2 weeks (Q2W), CZP 200 mg Q2W (400 mg weeks 0/2/4), or placebo Q2W. Outcomes assessed to week 16: PASI 75, PASI 90, PGA 0/1 (Markov chain Monte Carlo), Dermatology Life Quality Index (DLQI 0/1) and Itch Numeric Rating Scale (INRS 0) (non-responder imputation), and DLQI and INRS change from baseline (last observation carried forward). Safety data were reported for patients receiving ≥ 1 dose of study medication through weeks 0-16; adverse events were evaluated using Medical Dictionary for Regulatory Activities version 18.1.ResultsA total of 127 patients were randomized to CZP 400 mg Q2W (N = 53), CZP 200 mg Q2W (N = 48), placebo (N = 26). Week 16 responder rates for CZP 400 mg/200 mg Q2W versus placebo were 87.1%/73.0% versus 7.9% for PASI 75; 75.7%/53.8% versus 0.2% for PASI 90; 66.7%/52.7% versus 0.0% for PGA 0/1 (all p < 0.0001 for both CZP doses versus placebo). Significant improvements in DLQI and INRS were reported at week 16 by patients receiving both CZP doses compared with placebo (p < 0.0001). Incidence of treatment-emergent adverse events within the CZP 400 mg Q2W, CZP 200 mg Q2W, and placebo groups were 326.1, 404.9, and 682.4 per 100 patient-years. No new safety signals were identified compared to previously reported data.ConclusionCZP dosed at 400 mg or 200 mg Q2W was associated with improved PSO signs and symptoms.Trial registrationClinicalTrials.gov identifier, NCT03051217.

Project description:IntroductionCertolizumab pegol (CZP), an Fc-free, PEGylated anti-tumour necrosis factor biologic, dosed at 400 mg every 2 weeks (Q2W) and 200 mg Q2W over 16 weeks, resulted in improvements in Japanese patients with moderate to severe plaque psoriasis (PSO); no new safety signals were identified. We present 52-week efficacy and safety results.MethodsPatients ≥ 20 years with PSO ≥ 6 months [Psoriasis Area and Severity Index (PASI) ≥ 12, body surface area ≥ 10%, Physician's Global Assessment (PGA) ≥ 3] were randomised 1:2:2 to placebo Q2W, CZP 400 mg Q2W and CZP 200 mg Q2W (400 mg weeks 0/2/4) for 16 weeks. Week 16 PASI 50 responders continued through week 52; CZP 200 mg Q2W-randomised patients were re-randomised 1:1 to CZP 200 mg Q2W or CZP 400 mg Q4W; patients initially randomised to other treatment groups continued in the same group. Outcomes included PASI 75/90/100, PGA 0/1, Dermatology Life Quality Index (DLQI) 0/1, Itch Numeric Rating Scale (INRS) 0, modified Nail Psoriasis Severity Index (mNAPSI), durability of response for week 16 PASI 75/90 responders, and safety.ResultsOf 26/53/48 patients randomised to placebo, CZP 400 mg Q2W and CZP 200 mg Q2W, 2/47/39 completed week 52, respectively. PASI 75/90 responses were generally maintained from weeks 16 to 52 for all CZP doses. Most week 16 PASI 75/90 achievers maintained their response through week 52. PASI 75/90/100 responses at week 52 in the CZP 400 mg Q2W and CZP 200 mg Q2W groups were 83.0/81.1/41.5% and 72.9/60.4/18.8%, respectively; DLQI/INRS remission rates were 64.2/50.9% in CZP 400 mg Q2W and 58.3/27.1% in CZP 200 mg Q2W-treated patients. Reductions in mNAPSI observed for CZP-treated groups were maintained through week 52. No new safety signals were identified.ConclusionCZP treatment resulted in improvements in signs and symptoms of PSO, which were maintained through week 52. The 400 mg Q2W dose could provide additional clinical benefit.Trial registrationNCT03051217.

Project description:BackgroundPsoriasis is a chronic immune-mediated inflammatory systemic disease with skin manifestations characterized by erythematous, scaly, itchy and/or painful plaques resulting from hyperproliferation of keratinocytes. Certolizumab pegol [CZP], a PEGylated antigen binding fragment of a humanized monoclonal antibody against TNF-alpha, is approved for the treatment of moderate-to-severe plaque psoriasis. Patients with psoriasis present clinical and molecular variability, affecting response to treatment. Herein, we utilized an in silico approach to model the effects of CZP in a virtual population (vPop) with moderate-to-severe psoriasis. Our proof-of-concept study aims to assess the performance of our model in generating a vPop and defining CZP response variability based on patient profiles.MethodsWe built a quantitative systems pharmacology (QSP) model of a clinical trial-like vPop with moderate-to-severe psoriasis treated with two dosing schemes of CZP (200 mg and 400 mg, both every two weeks for 16 weeks, starting with a loading dose of CZP 400 mg at weeks 0, 2, and 4). We applied different modelling approaches: (i) an algorithm to generate vPop according to reference population values and comorbidity frequencies in real-world populations; (ii) physiologically based pharmacokinetic (PBPK) models of CZP dosing schemes in each virtual patient; and (iii) systems biology-based models of the mechanism of action (MoA) of the drug.ResultsThe combination of our different modelling approaches yielded a vPop distribution and a PBPK model that aligned with existing literature. Our systems biology and QSP models reproduced known biological and clinical activity, presenting outcomes correlating with clinical efficacy measures. We identified distinct clusters of virtual patients based on their psoriasis-related protein predicted activity when treated with CZP, which could help unravel differences in drug efficacy in diverse subpopulations. Moreover, our models revealed clusters of MoA solutions irrespective of the dosing regimen employed.ConclusionOur study provided patient specific QSP models that reproduced clinical and molecular efficacy features, supporting the use of computational methods as modelling strategy to explore drug response variability. This might shed light on the differences in drug efficacy in diverse subpopulations, especially useful in complex diseases such as psoriasis, through the generation of mechanistically based hypotheses.

Project description:IntroductionWe present certolizumab pegol (CZP) efficacy data across patient demographic and baseline disease characteristic subgroups from a phase 2/3 trial investigating CZP treatment in Japanese patients with moderate to severe plaque psoriasis (PSO; ClinicalTrials.gov identifier: NCT03051217).MethodsPatients were randomised 1:2:2 to placebo once every 2 weeks (Q2W), CZP 400 mg Q2W and CZP 200 mg Q2W (400 mg weeks 0, 2 and 4) for 16 weeks. Patients who achieved ≥ 50% reduction in their baseline Psoriasis Area and Severity Index (PASI 50) score at week 16 continued therapy to week 52. PASI 75/90 (75% and 90% reduction, respectively) and Physician's Global Assessment (PGA) 0/1 responder rates at weeks 16 and 52 were reported for patient demographic and baseline disease characteristic subgroups, including body mass index (BMI), PASI, disease duration and prior biologic use. Non-responder imputation was used.ResultsOf the randomised patients, 2/26 patients in the placebo group, 47/53 patients in the CZP 400 mg Q2W group and and 39/48 patients in the CZP 200 mg Q2W group completed week 52. In the subgroups evaluated, week 16 efficacy was generally maintained through week 52. At week 52, PASI 75 was achieved by 84.2, 85.7 and 80.0% of patients receiving CZP 400 mg Q2W in the low (15.0-23.7 kg/m2)/intermediate (> 23.7-27.4 kg/m2)/high (> 27.4-47.0 kg/m2) BMI subgroups, respectively, and by 77.8, 70.6 and 69.2%, respectively of patients treated with CZP 200 mg Q2W. PASI 75 at week 52 was achieved by 92.9, 75.0 and 84.2% of patients receiving CZP 400 mg Q2W in the low (12.0-18.0)/intermediate (> 18.0-27.0)/high (> 27.0-67.2) baseline PASI subgroups, respectively, and by 85.0, 58.3 and 68.8% of patients receiving CZP 200 mg Q2W, respectively. Similar responses were observed across other subgroups evaluated for both CZP doses in PASI 75/90 and PGA 0/1.ConclusionClinically meaningful improvements in signs and symptoms of PSO were maintained through week 52 for CZP dosed at 400 mg Q2W or 200 mg Q2W, across patient subgroups. In general, a numerically greater response was observed for patients receiving CZP 400 mg Q2W versus those receiving CZP 200 mg Q2W across patient subgroups.Trial registrationClinicalTrials.gov identifier, NCT03051217.
