Certolizumab Pegol for the Treatment of Moderate to Severe Plaque Psoriasis: 16-Week Results from a Phase 2/3 Japanese Study

Current Treatments for Generalized Pustular Psoriasis: A Narrative Summary of a Systematic Literature Search

Generalized pustular psoriasis (GPP) is a rare, chronic and potentially life-threatening autoinflammatory skin disease characterized by widespread eruption of sterile pustules, with or without systemic inflammation. GPP can significantly reduce patients' quality of life (QoL). Several therapeutic approaches have been described in the literature, but there is no consensus on optimal treatment. In this review, we summarize published literature on efficacy, safety and QoL outcomes associated with current treatment of GPP with both approved and non-approved products. Embase and MEDLINE databases were searched (1980-September 2023). A search protocol was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered on the PROSPERO database (CRD42021215437). Details on publication, population, intervention, efficacy, safety and QoL were captured and checked by independent reviewers. In total, 118 publications were included, with only 19% of publications reporting on the results of clinical trials. Treatment modalities reported for GPP included non-biologic systemic therapies such as retinoids, cyclosporine and methotrexate, topical agents, biologics and small molecules, among others. Results were highly heterogeneous and methodological quality was very low, with only the interleukin-36R inhibitor spesolimab reporting results from placebo-controlled randomized trials; based on this, spesolimab is now approved for GPP treatment in regions including the USA, Japan, China, the EU and several other countries. Some other biologics are approved exclusively in Japan and Taiwan for the treatment of GPP based on open-label studies with small patient numbers in lieu of double-blind studies. Non-standardization of clinical outcomes across studies remains a major hurdle in reaching a consensus on optimal treatment. However, recently trials have been conducted using well-defined, disease-specific endpoints to evaluate GPP-targeted treatments, which will hopefully advance patient care. In conclusion, this review highlights the need for prospective randomized studies with GPP-specific endpoints to determine the optimal treatment strategy.

A systematic review of 454 randomized controlled trials using the Dermatology Life Quality Index: experience in 69 diseases and 43 countries

BACKGROUND

Over 29 years of clinical application, the Dermatology Life Quality Index (DLQI) has remained the most used patient-reported outcome (PRO) in dermatology due to its robustness, simplicity and ease of use.

OBJECTIVES

To generate further evidence of the DLQI's utility in randomized controlled trials (RCTs) and to cover all diseases and interventions.

METHODS

The methodology followed PRISMA guidelines and included seven bibliographical databases, searching articles published from 1 January 1994 until 16 November 2021. Articles were reviewed independently by two assessors, and an adjudicator resolved any opinion differences.

RESULTS

Of 3220 screened publications, 454 articles meeting the eligibility criteria for inclusion, describing research on 198 190 patients, were analysed. DLQI scores were primary endpoints in 24 (5.3%) of studies. Most studies were of psoriasis (54.1%), although 69 different diseases were studied. Most study drugs were systemic (85.1%), with biologics comprising 55.9% of all pharmacological interventions. Topical treatments comprised 17.0% of total pharmacological interventions. Nonpharmacological interventions, mainly laser therapy and ultraviolet radiation treatment, comprised 12.2% of the total number of interventions. The majority of studies (63.7%) were multicentric, with trials conducted in at least 42 different countries; 40.2% were conducted in multiple countries. The minimal clinically importance difference (MCID) was reported in the analysis of 15.0% of studies, but only 1.3% considered full score meaning banding of the DLQI. Forty-seven (10.4%) of the studies investigated statistical correlation of the DLQI with clinical severity assessment or other PRO/quality of life tools; and 61-86% of studies had within-group scores differences greater than the MCID in 'active treatment arms'. The Jadad risk-of-bias scale showed that bias was generally low, as 91.8% of the studies had Jadad scores of ≥ 3; only 0.4% of studies showed a high risk of bias from randomization. Thirteen per cent had a high risk of bias from blinding and 10.1% had a high risk of bias from unknown outcomes of all participants in the studies. In 18.5% of the studies the authors declared that they followed an intention-to-treat protocol; imputation for missing DLQI data was used in 34.4% of studies.

CONCLUSIONS

This systematic review provides a wealth of evidence of the use of the DLQI in clinical trials to inform researchers' and -clinicians' decisions for its further use. Recommendations are also made for improving the reporting of data from future RCTs using the DLQI.

A systematic review investigating at what proportion clinical images are shared in prospective randomized controlled trials involving patients with psoriasis and biological agents

For many patients including those with psoriasis, scientific manuscripts comprising clinical outcomes including psoriasis area severity index (PASI) and/or physician global assessment (PGA) may be difficult to understand. However, most patients can relate to images at baseline and follow-up, particularly for dermatological diseases. This study aimed to assess the proportion of shared clinical images in psoriasis trials. A systematic review adhering to the PRISMA guidelines was performed. The review was limited to randomized controlled trials, and among these, only investigations involving biological agents for treatment of psoriasis were included. The Embase, MEDLINE and Scopus databases were searched for eligible studies published from inception to October 26, 2021. In total, 152 studies were included. When combining these, 62,871 patients were randomized. Overall, 203 images were shared depicting 60 patients in the manuscripts yielding an overall sharing rate of 0.1%. Patient images are seldom incorporated in clinical trial manuscripts which impairs interpretation for patients. Inclusion of image material would strengthen the patients' perspective and understanding on what treatment effects that can be expected. As such, this systematic review should be an invitation to the pharmaceutical industry, other sponsors, and editorial offices to improve easy transfer of information to patients using image data.

Short-, Mid-, and Long-Term Efficacy of Deucravacitinib Versus Biologics and Nonbiologics for Plaque Psoriasis: A Network Meta-Analysis

INTRODUCTION

Deucravacitinib, a newly approved oral medication for the treatment of patients with moderate to severe plaque psoriasis, demonstrated efficacy versus apremilast and placebo in two phase 3 randomized controlled trials (RCTs). A systematic review and network meta-analysis (NMA) indirectly compared deucravacitinib with other relevant systemic biologic/nonbiologic treatments.

METHODS

Online databases were searched for RCTs published through October 2021. Eligible studies were head-to-head comparisons between systemic therapies and/or placebo reporting 50%, 75%, 90%, or 100% improvement in Psoriasis Area and Severity Index (PASI) from baseline in adults with moderate to severe plaque psoriasis. Comparisons included tumor necrosis factor inhibitors, interleukin (IL)-17, IL-23, and IL 12/23 inhibitors, and systemic nonbiologics. A multinomial Bayesian NMA was used to derive estimates of the relative efficacy of deucravacitinib and other systemic therapies. Response probabilities for each treatment and corresponding 95% credible intervals (CrIs) for achieving a PASI response were calculated over short-, mid-, and long-term follow-up (weeks 10-16, 24-28, and 44-60).

RESULTS

The NMA included 47 RCTs. Deucravacitinib showed the highest PASI 75 response rates among nonbiologic systemic therapies across time points. Deucravacitinib PASI 75 response rate (95% CrI) over short-term follow-up was 54.1% (46.5-61.6), within the range of first-generation biologics (etanercept, 39.7% [31.6-48.3]; infliximab, 79.0% [74.0-83.5]). At mid-term follow-up, deucravacitinib PASI 75 increased to 63.3% (58.0-68.4). At long-term follow-up, deucravacitinib PASI 75 was 65.9% (58.0-73.4), comparable to first-generation biologics adalimumab (62.8%; 55.3-69.6) and ustekinumab (68.0%; 64.6-71.5).

CONCLUSIONS

Patients receiving deucravacitinib were more likely to achieve PASI 75 response versus apremilast and methotrexate across all time points. The long-term PASI 75 response rate for deucravacitinib was similar to those of adalimumab and ustekinumab. The approval of deucravacitinib offers patients the choice of an oral therapy with long-term efficacy similar to that of some biologics.

Systemic pharmacological treatments for chronic plaque psoriasis: a network meta-analysis

BACKGROUND

Psoriasis is an immune-mediated disease with either skin or joints manifestations, or both, and it has a major impact on quality of life. Although there is currently no cure for psoriasis, various treatment strategies allow sustained control of disease signs and symptoms. The relative benefit of these treatments remains unclear due to the limited number of trials comparing them directly head-to-head, which is why we chose to conduct a network meta-analysis.

OBJECTIVES

To compare the benefits and harms of non-biological systemic agents, small molecules, and biologics for people with moderate-to-severe psoriasis using a network meta-analysis, and to provide a ranking of these treatments according to their benefits and harms.

SEARCH METHODS

For this update of the living systematic review, we updated our searches of the following databases monthly to October 2022: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of systemic treatments in adults over 18 years with moderate-to-severe plaque psoriasis, at any stage of treatment, compared to placebo or another active agent. The primary outcomes were: proportion of participants who achieved clear or almost clear skin, that is, at least Psoriasis Area and Severity Index (PASI) 90; proportion of participants with serious adverse events (SAEs) at induction phase (8 to 24 weeks after randomisation).

DATA COLLECTION AND ANALYSIS

We conducted duplicate study selection, data extraction, risk of bias assessment, and analyses. We synthesised data using pairwise and network meta-analysis (NMA) to compare treatments and rank them according to effectiveness (PASI 90 score) and acceptability (inverse of SAEs). We assessed the certainty of NMA evidence for the two primary outcomes and all comparisons using CINeMA, as very low, low, moderate, or high. We contacted study authors when data were unclear or missing. We used the surface under the cumulative ranking curve (SUCRA) to infer treatment hierarchy, from 0% (worst for effectiveness or safety) to 100% (best for effectiveness or safety).

MAIN RESULTS

This update includes an additional 12 studies, taking the total number of included studies to 179, and randomised participants to 62,339, 67.1% men, mainly recruited from hospitals. Average age was 44.6 years, mean PASI score at baseline was 20.4 (range: 9.5 to 39). Most studies were placebo-controlled (56%). We assessed a total of 20 treatments. Most (152) trials were multicentric (two to 231 centres). One-third of the studies (65/179) had high risk of bias, 24 unclear risk, and most (90) low risk. Most studies (138/179) declared funding by a pharmaceutical company, and 24 studies did not report a funding source. Network meta-analysis at class level showed that all interventions (non-biological systemic agents, small molecules, and biological treatments) showed a higher proportion of patients reaching PASI 90 than placebo. Anti-IL17 treatment showed a higher proportion of patients reaching PASI 90 compared to all the interventions. Biologic treatments anti-IL17, anti-IL12/23, anti-IL23, and anti-TNF alpha showed a higher proportion of patients reaching PASI 90 than the non-biological systemic agents. For reaching PASI 90, the most effective drugs when compared to placebo were (SUCRA rank order, all high-certainty evidence): infliximab (risk ratio (RR) 49.16, 95% CI 20.49 to 117.95), bimekizumab (RR 27.86, 95% CI 23.56 to 32.94), ixekizumab (RR 27.35, 95% CI 23.15 to 32.29), risankizumab (RR 26.16, 95% CI 22.03 to 31.07). Clinical effectiveness of these drugs was similar when compared against each other. Bimekizumab and ixekizumab were significantly more likely to reach PASI 90 than secukinumab. Bimekizumab, ixekizumab, and risankizumab were significantly more likely to reach PASI 90 than brodalumab and guselkumab. Infliximab, anti-IL17 drugs (bimekizumab, ixekizumab, secukinumab, and brodalumab), and anti-IL23 drugs except tildrakizumab were significantly more likely to reach PASI 90 than ustekinumab, three anti-TNF alpha agents, and deucravacitinib. Ustekinumab was superior to certolizumab. Adalimumab, tildrakizumab, and ustekinumab were superior to etanercept. No significant difference was shown between apremilast and two non-biological drugs: ciclosporin and methotrexate. We found no significant difference between any of the interventions and the placebo for the risk of SAEs. The risk of SAEs was significantly lower for participants on methotrexate compared with most of the interventions. Nevertheless, the SAE analyses were based on a very low number of events with very low- to moderate-certainty evidence for all the comparisons. The findings therefore have to be viewed with caution. For other efficacy outcomes (PASI 75 and Physician Global Assessment (PGA) 0/1), the results were similar to the results for PASI 90. Information on quality of life was often poorly reported and was absent for several of the interventions.

AUTHORS' CONCLUSIONS

Our review shows that, compared to placebo, the biologics infliximab, bimekizumab, ixekizumab, and risankizumab were the most effective treatments for achieving PASI 90 in people with moderate-to-severe psoriasis on the basis of high-certainty evidence. This NMA evidence is limited to induction therapy (outcomes measured from 8 to 24 weeks after randomisation), and is not sufficient for evaluating longer-term outcomes in this chronic disease. Moreover, we found low numbers of studies for some of the interventions, and the young age (mean 44.6 years) and high level of disease severity (PASI 20.4 at baseline) may not be typical of patients seen in daily clinical practice. We found no significant difference in the assessed interventions and placebo in terms of SAEs, and the safety evidence for most interventions was very low to moderate quality. More randomised trials directly comparing active agents are needed, and these should include systematic subgroup analyses (sex, age, ethnicity, comorbidities, psoriatic arthritis). To provide long-term information on the safety of treatments included in this review, an evaluation of non-randomised studies is needed. Editorial note: This is a living systematic review. Living systematic reviews offer a new approach to review updating, in which the review is continually updated, incorporating relevant new evidence as it becomes available.

Impact of targeted therapies on the risk of cardiovascular events in patients with psoriasis and psoriatic arthritis: A systematic review and aggregate data meta-analysis of randomized controlled trials

OBJECTIVE

We aimed to investigate the effect of targeted therapies on cardiovascular risk in psoriasis (PsO) and psoriatic arthritis (PsA) via a meta-analysis of randomized controlled trials (RCTs).

METHODS

Pubmed, Embase, Cochrane Library, and Scopus were searched for RCTs reporting targeted therapies in patients with PsO/PsA published until 28 October 2021. The primary and secondary outcomes included the relationship between targeted therapies and all cardiovascular events (CVEs), major adverse cardiovascular events (MACEs), myocardial infarction (MI), heart failure, and stroke in PsO/PsA. The outcome risk ratios (RRs) were calculated using the Mantel-Haenszel fixed-effect method.

RESULTS

A total of 81 articles involving 88 RCTs were included. There was no statistically significant difference regarding the occurrence of all CVEs for all targeted therapies (RR = 1.03, 95% CI 0.74-1.43, P = .85) compared to placebo in PsO/PsA. No statistically significant difference existed between drugs and placebo in patients with PsA on all CVEs (RR = 0.81, 95% CI 0.48-1.36, P = .43). Surprisingly, the incidence of all CVEs was higher in the low dosage group compared to the high dosage group of all targeted therapies (RR = 1.97, 95% CI 1.19-3.27, P = .008) and prominently anti-interleukin-17 agent (RR = 2.20, 95% CI 1.05-4.58, P = .04).

CONCLUSION

Current targeted therapies are not associated with the risk of CVEs. Based on the existing evidence, we reported here that a dosage reduction of targeted therapies was not recommended.

Infection risk in psoriatic patients receiving tumour necrosis factor inhibitors: a 20-year systematic review and meta-analysis of randomized controlled trials

Tumour necrosis factor inhibitors (TNFis) are commonly used for treating psoriatic diseases; however, the risk of infection while receiving TNFis remains uncertain. The aim of this study was to investigate the infection risk in patients with psoriatic disease receiving TNFis. A prospectively registered systematic literature search was conducted in Medline (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and the ClinicalTrials.gov databases from inception to December 31, 2021. We included double-blind randomized controlled trials that compared TNFis or other biologics with placebo in adults with psoriasis or psoriatic arthritis. The primary outcomes included overall and serious infection risks, and secondary outcomes included upper respiratory infections and nasopharyngitis risks. The risk ratio of the dichotomous outcome was calculated using the Mantel-Haenszel method with random effects, and heterogeneity was assessed using Cochran's Q statistic and quantified using the I-squared statistic. A total of 48 studies with 15 464 patients with psoriatic diseases were included. The meta-analysis demonstrated a slightly increased overall infection risk (risk ratio = 1.09; 95% confidence interval, 1.02-1.15) but not serious infection risk (risk ratio = 0.95; 95% confidence interval, 0.61-1.49) among patients receiving TNFis. There were also no increased risks of upper respiratory infections (risk ratio = 1.10; 95% confidence interval, 0.94-1.28) or nasopharyngitis (risk ratio = 1.14; 95% confidence interval, 1.00-1.30). In subgroup analyses using the fixed effects model, only etanercept and certolizumab pegol were, respectively, associated with an increased risk of overall infection (RR = 1.14, 95% CI, 1.03-1.27) and upper respiratory infections (RR = 1.42, 95% CI, 1.02-1.98). In conclusion, evidence to date suggests an increased overall infection risk that is generally tolerable in patients with psoriatic diseases receiving TNFis. There are no increased risks of serious infections, upper respiratory infections or nasopharyngitis.

Efficacy and Safety of Certolizumab Pegol in Japanese Patients with Generalized Pustular Psoriasis and Erythrodermic Psoriasis: 52-Week Results

Introduction

We report an exploratory analysis of the efficacy and safety of certolizumab pegol (CZP) in Japanese patients with generalized pustular psoriasis (GPP) and erythrodermic psoriasis (EP) (NCT03051217).

Methods

Patients ≥ 20 years with GPP or EP were randomized 1:1 to open-label CZP 400 mg every 2 weeks (Q2W) or 200 mg Q2W (400 mg weeks 0/2/4) for 16 weeks; patients who achieved “much improved” or “very much improved” on the Global Improvement Score (GIS; for GPP) or a PASI 50 response (≥ 50% reduction from baseline Psoriasis Area and Severity Index; for EP) continued to week 52. Efficacy outcomes assessed included Clinical Global Impression of Improvement (CGI-I), Dermatology Life Quality Index (DLQI 0/1), and Itch Numeric Rating Scale (INRS 0). GIS and Japanese Dermatological Association (JDA) severity index were assessed in patients with GPP, and PASI and Physician’s Global Assessment (PGA) in patients with EP. Treatment-emergent adverse events (TEAEs) were evaluated through weeks 0–52.

Results

Of 22 patients randomized, 19 completed week 52. At week 16, all reported outcomes improved with both CZP doses and were generally maintained through week 52. At week 52, 6/7 GPP and 12/12 EP patients achieved CGI-I response (“improved” or “remission”). Also, 4/7 GPP and 7/12 EP patients achieved DLQI 0/1; 2/7 GPP and 2/12 EP patients achieved INRS 0. Meanwhile, 6/7 patients with GPP achieved GIS response, and JDA severity index was reduced from baseline. We found that 9/12 and 5/12 patients with EP achieved PASI 90 and PGA 0/1, respectively. Overall, three serious TEAEs were reported in three CZP 400 mg Q2W-treated patients.

Conclusion

CZP treatment over 16 weeks improved the signs and symptoms of GPP and EP, and improvements were maintained through week 52. No new safety signals were identified.

Systemic pharmacological treatments for chronic plaque psoriasis: a network meta-analysis

BACKGROUND

Psoriasis is an immune-mediated disease with either skin or joints manifestations, or both, and it has a major impact on quality of life. Although there is currently no cure for psoriasis, various treatment strategies allow sustained control of disease signs and symptoms. The relative benefit of these treatments remains unclear due to the limited number of trials comparing them directly head-to-head, which is why we chose to conduct a network meta-analysis.

OBJECTIVES

To compare the efficacy and safety of non-biological systemic agents, small molecules, and biologics for people with moderate-to-severe psoriasis using a network meta-analysis, and to provide a ranking of these treatments according to their efficacy and safety.

SEARCH METHODS

For this update of the living systematic review, we updated our searches of the following databases monthly to October 2021: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase.

SELECTION CRITERIA

Randomised controlled trials (RCTs) of systemic treatments in adults over 18 years with moderate-to-severe plaque psoriasis, at any stage of treatment, compared to placebo or another active agent. The primary outcomes were: proportion of participants who achieved clear or almost clear skin, that is, at least Psoriasis Area and Severity Index (PASI) 90; proportion of participants with serious adverse events (SAEs) at induction phase (8 to 24 weeks after randomisation).

We conducted duplicate study selection, data extraction, risk of bias assessment and analyses. We synthesised data using pairwise and network meta-analysis (NMA) to compare treatments and rank them according to effectiveness (PASI 90 score) and acceptability (inverse of SAEs). We assessed the certainty of NMA evidence for the two primary outcomes and all comparisons using CINeMA, as very low, low, moderate, or high. We contacted study authors when data were unclear or missing. We used the surface under the cumulative ranking curve (SUCRA) to infer treatment hierarchy, from 0% (worst for effectiveness or safety) to 100% (best for effectiveness or safety).

MAIN RESULTS

This update includes an additional 19 studies, taking the total number of included studies to 167, and randomised participants to 58,912, 67.2% men, mainly recruited from hospitals. Average age was 44.5 years, mean PASI score at baseline was 20.4 (range: 9.5 to 39). Most studies were placebo-controlled (57%). We assessed a total of 20 treatments. Most (140) trials were multicentric (two to 231 centres). One-third of the studies (57/167) had high risk of bias; 23 unclear risk, and most (87) low risk. Most studies (127/167) declared funding by a pharmaceutical company, and 24 studies did not report a funding source. Network meta-analysis at class level showed that all interventions (non-biological systemic agents, small molecules, and biological treatments) showed a higher proportion of patients reaching PASI 90 than placebo. Anti-IL17 treatment showed a higher proportion of patients reaching PASI 90 compared to all the interventions, except anti-IL23. Biologic treatments anti-IL17, anti-IL12/23, anti-IL23 and anti-TNF alpha showed a higher proportion of patients reaching PASI 90 than the non-biological systemic agents. For reaching PASI 90, the most effective drugs when compared to placebo were (SUCRA rank order, all high-certainty evidence): infliximab (risk ratio (RR) 50.19, 95% CI 20.92 to 120.45), bimekizumab (RR 30.27, 95% CI 25.45 to 36.01), ixekizumab (RR 30.19, 95% CI 25.38 to 35.93), risankizumab (RR 28.75, 95% CI 24.03 to 34.39). Clinical effectiveness of these drugs was similar when compared against each other. Bimekizumab, ixekizumab and risankizumab showed a higher proportion of patients reaching PASI 90 than other anti-IL17 drugs (secukinumab and brodalumab) and guselkumab. Infliximab, anti-IL17 drugs (bimekizumab, ixekizumab, secukinumab and brodalumab) and anti-IL23 drugs (risankizumab and guselkumab) except tildrakizumab showed a higher proportion of patients reaching PASI 90 than ustekinumab and three anti-TNF alpha agents (adalimumab, certolizumab and etanercept). Ustekinumab was superior to certolizumab; adalimumab and ustekinumab were superior to etanercept. No significant difference was shown between apremilast and two non-biological drugs: ciclosporin and methotrexate. We found no significant difference between any of the interventions and the placebo for the risk of SAEs. The risk of SAEs was significantly lower for participants on methotrexate compared with most of the interventions. Nevertheless, the SAE analyses were based on a very low number of events with low- to moderate-certainty for all the comparisons (except methotrexate versus placebo, which was high-certainty). The findings therefore have to be viewed with caution. For other efficacy outcomes (PASI 75 and Physician Global Assessment (PGA) 0/1), the results were similar to the results for PASI 90. Information on quality of life was often poorly reported and was absent for several of the interventions.

AUTHORS' CONCLUSIONS

Our review shows that, compared to placebo, the biologics infliximab, bimekizumab, ixekizumab, and risankizumab were the most effective treatments for achieving PASI 90 in people with moderate-to-severe psoriasis on the basis of high-certainty evidence. This NMA evidence is limited to induction therapy (outcomes measured from 8 to 24 weeks after randomisation), and is not sufficient for evaluating longer-term outcomes in this chronic disease. Moreover, we found low numbers of studies for some of the interventions, and the young age (mean 44.5 years) and high level of disease severity (PASI 20.4 at baseline) may not be typical of patients seen in daily clinical practice. We found no significant difference in the assessed interventions and placebo in terms of SAEs, and the safety evidence for most interventions was low to moderate quality. More randomised trials directly comparing active agents are needed, and these should include systematic subgroup analyses (sex, age, ethnicity, comorbidities, psoriatic arthritis). To provide long-term information on the safety of treatments included in this review, an evaluation of non-randomised studies and postmarketing reports from regulatory agencies is needed.

Can Performance and Gentleness Be Reconciled? A Skin Care Approach for Sensitive Skin

People with self-reported sensitive skin may reluctantly use performing anti-ageing skin care products as it could elicit skin discomfort. We thus aimed to design and test an anti-ageing skin care routine that is suitable for people reporting sensitive skin. Key principles for developing products for sensitive skin were applied and formulas were screened for their mildness in vitro using the Reconstructed Human Epidermis ET50 method. Anti-ageing efficacy and mildness was evaluated during a clinical study in China, with 33 female volunteers aged 40–65 years, with sensitive skin. The anti-ageing benefits were measured using Primos 3D, the cutometer and clinical evaluation. Hallmarks for sensitive skin such as skin hydration, skin barrier, skin redness and response to lactic acid were also measured. The ET50 method yielded values suggesting moderate to mild expected irritancy effect in vivo for most of them, and non-irritating effect for the serum. During the clinical study, no physical or functional signs of discomfort were reported with twice-daily usage of the routine. Instrumental evaluation of Wrinkle depth, skin elasticity/firmness, skin hydration, skin barrier and skin redness revealed improvement at 4 and 8 weeks. Clinical evaluation evidenced skin smoothness, skin suppleness and radiance improvements. The skin was less reactive to lactic acid stimuli, while the sensitive skin burden was lowered according to the dermatological quality of life index. Lastly, a separate investigation suggested the potential relief aspect of such routines to alleviate discomforts from mask wearing. With the right formulation design, the benefits of layering products from a routine can be made accessible to people with sensitive skin while simultaneously alleviating the burden of sensitive skin.

Certolizumab Pegol in Japanese Patients with Moderate to Severe Plaque Psoriasis: Effect of Demographics and Baseline Disease Characteristics on Efficacy

Introduction

We 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).

Methods

Patients 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.

Results

Of 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.

Conclusion

Clinically 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.

Efficacy and Safety of Certolizumab Pegol in Japanese Patients with Moderate to Severe Plaque Psoriasis: 52-Week Results

Introduction

Certolizumab 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.

Methods

Patients ≥ 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.

Results

Of 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.

Conclusion

CZP 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.
