Upadacitinib for moderate-to-severe atopic dermatitis: Stratified analysis from three randomized phase 3 trials by key baseline characteristics.

BACKGROUND: Atopic dermatitis (AD) is a heterogeneous inflammatory skin disease with different clinical phenotypes based on factors such as age, race, comorbidities, and clinical signs and symptoms. The effect of these factors on therapeutic responses in AD has only been scarcely studied and not for upadacitinib. Currently, there is no biomarker predicting response to upadacitinib. OBJECTIVES: Evaluate the efficacy of the oral Janus kinase inhibitor upadacitinib across patient subgroups (baseline demographics, disease characteristics and prior treatment) in patients with moderate-to-severe AD. METHODS: Data from phase 3 studies (Measure Up 1, Measure Up 2 and AD Up) were utilized for this post hoc analysis. Adults and adolescents with moderate-to-severe AD were randomized to receive once daily oral upadacitinib 15 mg, upadacitinib 30 mg or placebo; patients enrolled in the AD Up study received concomitant topical corticosteroids. Data from the Measure Up 1 and Measure Up 2 studies were integrated. RESULTS: A total of 2584 patients were randomized. A consistently greater proportion of patients achieved at least 75% improvement in the Eczema Area and Severity Index, a 0 or 1 on the validated Investigator Global Assessment for Atopic Dermatitis, and improvement in itch (including an achievement of a reduction of ≥4; and score of 0/1 in Worst Pruritus Numerical Rating Scale) with upadacitinib compared with placebo at Week 16, regardless of age, sex, race, body mass index, AD severity, body surface area involvement, history of atopic comorbidities or asthma, or previous exposure to systemic therapy or cyclosporin. CONCLUSIONS: Upadacitinib had consistently high skin clearance rates and itch efficacy across subgroups of patients with moderate-to-severe AD through Week 16. These results support upadacitinib as a suitable treatment option in a variety of patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifiers: NCT03569293 (Measure Up 1), NCT03607422 (Measure Up 2) and NCT03568318 (AD Up).

Expert consensus on the systemic treatment of atopic dermatitis in special populations.

With the increasing number of options for the treatment of moderate-to-severe atopic dermatitis, clinicians need guidance on a practical approach to selecting a systemic agent for specific patient populations. We convened an expert panel consisting of 12 members to conduct a literature review and summarize relevant data related to six scenarios of clinical interest: comorbid asthma, ocular surface disease, history of cancer, past and ongoing infections of interest (including herpes simplex virus, herpes zoster, hepatitis B, and tuberculosis), pregnancy and lactation, and the elderly. We performed a literature search and examined each clinical scenario with respect to three major categories of available systemic agents: traditional systemics (azathioprine, cyclosporine A, methotrexate, and mycophenolate mofetil), Janus kinase inhibitors (abrocitinib, baricitinib, and upadacitinib), and biologics (dupilumab, lebrikizumab, and tralokinumab). The expert panel and steering committee met virtually to review the data and discuss the drafted consensus statements. A modified Delphi process was used to arrive at a set of final consensus statements related to the systemic treatment of AD in these specific patient populations. To provide practical guidance on the choice of systemic therapy for atopic dermatitis in these six topics of clinical interest, 25 expert consensus statements and a summary of the supporting data are presented herein.

Tildrakizumab efficacy and safety in patients with psoriasis and concomitant metabolic syndrome: post hoc analysis of 5-year data from reSURFACE 1 and reSURFACE 2.

BACKGROUND: Limited data are available on long-term efficacy and safety of biologics in patients with psoriasis and metabolic syndrome (MetS), a common comorbidity. OBJECTIVES: This analysis updates tildrakizumab efficacy and safety for up to 5 years in patients with and without MetS. METHODS: This was a post hoc analysis of the double-blind, randomized, placebo-controlled, phase 3 reSURFACE 1 (NCT01722331) and reSURFACE 2 (NCT01729754) trials in adult patients with moderate to severe chronic plaque psoriasis. Analyses included data through Week 244 from patients who continuously received tildrakizumab 100 (TIL100) or 200 mg (TIL200) and entered the extension studies, stratified by baseline MetS status. Efficacy was assessed via Psoriasis Area and Severity Index (PASI) scores. Safety was evaluated from exposure-adjusted incidence rates (EAIRs) of treatment-emergent adverse events (TEAEs). RESULTS: reSURFACE 1 and reSURFACE 2 analyses included 26 and 44 TIL100-treated patients with MetS, 98 and 167 TIL100-treated patients without MetS, 34 and 30 TIL200-treated patients with MetS, and 111 and 130 TIL200-treated patients without MetS, respectively. There were no clinically relevant differences in PASI 75/90/100 response rates at Week 244 between patients with vs without MetS. The proportion of patients with vs without MetS achieving absolute PASI score <3 at Week 244 was 53.8% vs 69.4% and 77.3% vs 80.8% in reSURFACE 1 and 2, respectively, for TIL100-treated patients and 58.8% vs 72.1% and 63.3% vs 72.3%, respectively, for TIL200-treated patients. In both studies, median reduction from baseline PASI score at all time points in patients with vs without MetS was >83% vs >89% for TIL100 and >85% vs >90% for TIL200. Pooled EAIRs of TEAEs, serious TEAEs, and TEAEs of special interest were similar in patients with and without MetS. CONCLUSIONS: Tildrakizumab maintains efficacy and a favorable safety profile over 5 years in patients with psoriasis regardless of MetS status.

High threshold efficacy responses in moderate-to-severe atopic dermatitis are associated with additional quality of life benefits: pooled analyses of abrocitinib monotherapy studies in adults and adolescents.

BACKGROUND: Once-daily abrocitinib treatment provided meaningful improvements in signs and symptoms of moderate-to-severe atopic dermatitis (AD) in randomized controlled studies. OBJECTIVE: To evaluate proportions of patients with responses meeting higher threshold efficacy responses than commonly used efficacy end points and to determine if these responses were associated with quality-of-life (QoL) benefits. METHODS: Data from a phase 2b (NCT02780167) and two phase 3 studies (NCT03349060/JADE MONO-1; NCT03575871/JADE MONO-2) in adult and adolescent patients (N = 942) with moderate-to-severe AD receiving once-daily abrocitinib 200 mg, abrocitinib 100 mg or placebo were pooled. Commonly used (Eczema Area and Severity Index [EASI]-75 and ≥4-point improvement in Pruritus Numerical Rating Scale [PP-NRS4]) and higher threshold efficacy end points (EASI-90 to

Long-term, durable, absolute Psoriasis Area and Severity Index and health-related quality of life improvements with risankizumab treatment: a post hoc integrated analysis of patients with moderate-to-severe plaque psoriasis.

BACKGROUND: Risankizumab has demonstrated durable, high rates of efficacy in patients with moderate-to-severe plaque psoriasis as assessed by the achievement of relative Psoriasis Area and Severity Index (PASI) improvement and Dermatology Life Quality Index (DLQI) 0/1. OBJECTIVES: The aim of this post hoc analysis is to assess the achievement of absolute PASI thresholds and related improvements in health-related quality of life (HRQoL) in patients with moderate-to-severe plaque psoriasis treated with (i) risankizumab compared with ustekinumab, and (ii) long-term (>52 weeks to 172 weeks) risankizumab. METHODS: Data from patients randomised to 150 mg risankizumab or 45 or 90 mg ustekinumab in replicate randomised controlled trials UltIMMa-1 and UltIMMa-2 were analysed for the achievement of absolute PASI thresholds PASI ≤ 3, PASI ≤ 1, and PASI = 0, time to achieve these thresholds, and combined PASI and DLQI endpoints. Data from pat ients initially randomised to risankizumab who continued on risankizumab in the open-label extension study LIMMitless were analysed for the achievement of absolute PASI levels, mean DLQI scores, and DLQI 0/1. RESULTS: Significantly greater proportions of patients treated with risankizumab compared with ustekinumab achieved PASI ≤ 3, PASI ≤ 1, and PASI = 0, as well as combined endpoints for absolute PASI and DLQI [(PASI ≤ 3 and DLQI ≤ 5) or (PASI ≤ 1 and DLQI 0/1)]. The median time to first achieve PASI ≤ 3, PASI ≤ 1, and PASI = 0 was significantly lower for risankizumab-treated patients compared with ustekinumab-treated patients. Among patients treated with long-term risankizumab, more than 90% achieved PASI ≤ 3 though week 172 and more than 80% achieved DLQI 0/1. Low absolute PASI scores corresponded with low mean absolute DLQI scores through week 172 of continuous risankizumab treatment. CONCLUSIONS: Risankizumab treatment demonstrated high rates of rapid and durable efficacy as measured by absolute PASI thresholds and improvements in patient HRQoL.

Quality of life and patient-perceived symptoms in patients with psoriasis undergoing proactive or reactive management with the fixed-dose combination Cal/BD foam: A post-hoc analysis of PSO-LONG.

BACKGROUND: Psoriasis has important physical and psychosocial effects that extend beyond the skin. Understanding the impact of treatment on health-related quality of life (HRQoL) and patient-perceived symptom severity in psoriasis is key to clinical decision-making. OBJECTIVES: This post hoc analysis of the PSO-LONG trial data assessed the impact of long-term proactive or reactive management with fixed-dose combination calcipotriene 50 µg/g and betamethasone dipropionate 0.5 mg/g (Cal/BD) foam on patient-reported outcomes (PROs) in patients with psoriasis vulgaris. METHODS: Five hundred and twenty-one patients from the Phase 3, randomized, double-blind PSO-LONG trial were included. An initial 4-week, open-label phase of fixed-dose combination Cal/BD foam once daily (QD) was followed by a 52-week maintenance phase, at the start of which patients were randomized to a proactive management arm (Cal/BD foam twice weekly) or reactive management arm (vehicle foam twice weekly). Patient-perceived symptom severity and HRQoL were assessed using the Psoriasis Symptom Inventory (PSI), the Dermatology Life Quality Index (DLQI) and the EuroQol-5D for psoriasis (EQ-5D-5L-PSO). RESULTS: Statistically and clinically significant improvements were observed across all PRO measures. The mean difference (standard deviation) from baseline to Week 4 was -8.97 (6.18) for PSI, -6.02 (5.46) for DLQI and 0.11 (0.15) for EQ-5D-5L-PSO scores. During maintenance, patients receiving reactive management had significantly higher DLQI (15% [p = 0.007]) and PSI (15% [p = 0.0128]) and a numerically lower EQ-5D-5L-PSO mean area under the curve score than patients receiving proactive management (1% [p = 0.0842]). CONCLUSIONS: Cal/BD foam significantly improved DLQI, EQ-5D-5L-PSO and PSI scores during the open-label and maintenance phases. Patients assigned to proactive management had significantly better DLQI and PSI scores and numerically better EQ-5D-5L-PSO versus reactive management. Additionally, baseline flare was associated with worse PROs than the start of a relapse, and patients starting a relapse also had worse PROs than patients in remission.

Real-world effectiveness of adalimumab in patients with moderate-to-severe hidradenitis suppurativa: the 1-year SOLACE study.

BACKGROUND: Long-term, real-word data are needed to help manage patients with hidradenitis suppurativa (HS) through this recurrent, painful and debilitating disease. OBJECTIVES: To primarily measure real-world effectiveness of adalimumab in HS and to secondarily observe clinical course of HS in the light of patients' response. METHODS: In SOLACE, adults with moderate-to-severe HS in need for change in ongoing therapy were treated with adalimumab for up to 52 weeks as per physician's medical practice. Treatment effectiveness was measured by Hidradenitis Suppurativa Clinical Response (HiSCR). Inflammatory nodules, abscesses and draining fistulas were counted, Hurley stage was assessed, and disease severity was rated using the International HS Severity Scoring System (IHS4). A post hoc analysis further explored the HiSCR response by abscess and inflammatory nodule (AN) count at baseline (low, medium and high) and gender. Spontaneously reported safety events were collected. RESULTS: From 23 Canadian centres, 69% of the 138 patients achieved HiSCR at week 24, which increased to 82% and 75% at week 52 in patients with medium and high AN counts, respectively. Gender (4 times the odds for female) and age at HS onset (5% decrease with each additional year) had an effect on achieving HiSCR. Treatment with adalimumab led to an important decrease in number of lesions in responders, with most gains observed in inflammatory nodules, more frequently in the lower body area of patients in the high AN count group. The IHS4 scores of responders were substantially lowered, with a larger decrease in patients of the high AN count group. No new safety signal was detected. CONCLUSIONS: The effectiveness of adalimumab was maintained during this 1-year period, and an optimal gain was documented for patients with medium and high AN counts. These real-world data support a prompt treatment of HS patients and the use of IHS4 to monitor treatment.

Position statement for a pragmatic approach to immunotherapeutics in patients with inflammatory skin diseases during the coronavirus disease 2019 pandemic and beyond.

Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2, a novel RNA virus that was declared a global pandemic on 11 March 2020. The efficiency of infection with SARS-CoV-2 is reflected by its rapid global spread. The SARS-CoV-2 pandemic has implications for patients with inflammatory skin diseases on systemic immunotherapy who may be at increased risk of infection or more severe infection. This position paper is a focused examination of current evidence considering the mechanisms of action of immunotherapeutic drugs in relation to immune response to SARS-CoV-2. We aim to provide practical guidance for dermatologists managing patients with inflammatory skin conditions on systemic therapies during the current pandemic and beyond. Considering the limited and rapidly evolving evidence, mechanisms of action of therapies, and current knowledge of SARS-CoV-2 infection, we propose that systemic immunotherapy can be continued, with special considerations for at risk patients or those presenting with symptoms.

Pooled safety analysis of baricitinib in adult patients with atopic dermatitis from 8 randomized clinical trials.

BACKGROUND: Janus kinase (JAK) inhibition is a new mode of action in atopic dermatitis (AD); clarity about drug class safety considerations in the context of AD is important. Baricitinib, an oral, reversible, selective inhibitor of JAK1/JAK2, is in late-stage development for adult patients with moderate-to-severe AD. OBJECTIVE: To report pooled safety data for baricitinib in patients with moderate-to-severe AD in the clinical development program including long-term extension (LTE) studies. METHODS: This analysis included patient-level safety data from six double-blinded, randomized, placebo-controlled studies (one phase 2 and five phase 3), one double-blinded, randomized, LTE study and one open-label LTE study, reported in three data sets: placebo-controlled, 2-mg - 4-mg extended and All-bari AD. Safety outcomes include treatment-emergent adverse events, adverse events of special interest and abnormal laboratory changes. Proportions of patients with events and incidence rates were calculated. RESULTS: Data were collected for 2531 patients who were given baricitinib for 2247 patient-years (median duration 310 days). The frequency of serious infections, opportunistic infections and conjunctival disorders was low and similar between treatment groups in the placebo-controlled period. The most common serious infections were eczema herpeticum [n = 11, incidence rates (IR) = 0.5], cellulitis (n = 6, IR = 0.3) and pneumonia (n = 3, IR = 0.1). There were four opportunistic infections (IR = 0.2). No malignancies, gastrointestinal perforations, positively adjudicated cardiovascular events or tuberculosis were reported in the placebo-controlled period in baricitinib-treated patients. Frequency of herpes simplex was higher in the 4-mg group (6.1%) vs. the 2-mg (3.6%) and placebo group (2.7%); IRs in the extended data set (2-mg IR = 9.6; 4-mg IR = 14.5) were lower vs. the placebo-controlled data set (2-mg IR = 12.4; 4-mg IR = 21.3). In the All-bari AD data set, there were two positively adjudicated major adverse cardiovascular events (2-mg group): two venous thrombosis events (4-mg group) and one death. CONCLUSION: This integrated safety analysis in patients with moderate-to-severe AD confirms the established safety profile of baricitinib.

A head-to-head comparison of ixekizumab vs. guselkumab in patients with moderate-to-severe plaque psoriasis: 24-week efficacy and safety results from a randomized, double-blinded trial.

BACKGROUND: Significantly more patients with moderate-to-severe plaque psoriasis treated with the interleukin (IL)-17A inhibitor ixekizumab vs. the IL-23p19 inhibitor guselkumab in the IXORA-R head-to-head trial achieved 100% improvement in Psoriasis Area and Severity Index (PASI 100) at week 12. OBJECTIVES: To compare skin and nail clearance and patient-reported outcomes for ixekizumab vs. guselkumab, up to week 24. METHODS: IXORA-R enrolled adults with moderate-to-severe plaque psoriasis, defined as static Physician's Global Assessment ≥ 3, PASI ≥ 12 and involved body surface area ≥ 10%. Statistical comparisons were performed using the Cochran-Mantel-Haenszel test stratified by pooled site. Time-to-first-event comparisons were performed using Kaplan-Meier analysis, and P-values were generated using adjusted log-rank tests stratified by treatment group. Cumulative days at clinical and patient-reported responses were compared by ancova. The trial was registered with ClinicalTrials.gov (NCT03573323). RESULTS: Of the 1027 patients randomly assigned, 90% completed the trial (465 of 520 ixekizumab and 459 of 507 guselkumab). As early as week 2 and through week 16, more patients on ixekizumab achieved PASI 100 (P < 0·01). At week 24, ixekizumab was noninferior to guselkumab (50% vs. 52%, difference -2·3%), with no statistically significant difference in PASI 100 (P = 0·41). More patients receiving ixekizumab showed completely clear nails at week 24 (52% vs. 31%, P = 0·007). The median time to first PASI 50/75/90 and PASI 100 were 2 and 7·5 weeks shorter, respectively, for patients on ixekizumab vs. guselkumab (P < 0·001). Patients on ixekizumab also had a greater cumulative benefit, with more days at PASI 90 and 100, with Dermatology Life Quality Index of 0 or 1, and itch free (P < 0·05). The frequency of serious adverse events was 3% for each group, with no new safety signals. CONCLUSIONS: Ixekizumab was noninferior to guselkumab in complete skin clearance and superior in clearing nails at week 24. Ixekizumab cleared skin more rapidly in patients with moderate-to-severe plaque psoriasis, with a greater cumulative benefit, than guselkumab. Overall, the safety findings were consistent with the known safety profile for ixekizumab.

Safety in moderate-to-severe plaque psoriasis patients with latent tuberculosis treated with guselkumab and anti-tuberculosis treatments concomitantly: results from pooled phase 3 VOYAGE 1 & VOYAGE 2 trials.

BACKGROUND: Patients treated with tumour necrosis factor (TNF) inhibitors are at risk of new-onset tuberculosis (TB) or reactivation of latent tuberculosis infection (LTBI). Association between TB/LTBI and interleukin (IL)-23 inhibitors for psoriasis is unclear. Patients with LTBI typically initiate LTBI therapy before receiving biologics. OBJECTIVES: Safety in moderate-to-severe psoriasis patients with LTBI treated with guselkumab (IL-23 inhibitor) and LTBI treatment was evaluated. METHODS: In the VOYAGE 1 & VOYAGE 2 studies, patients screened for LTBI were randomized to guselkumab, placebo, or adalimumab (TNF inhibitor) at baseline. Placebo â†’ guselkumab crossover occurred at week 16 and adalimumab â†’ guselkumab at week 52 (VOYAGE 1), or at week 28 or later (VOYAGE 2). Incidence of active TB, adverse events (AEs), serious AEs (SAEs), and markedly abnormal liver function tests [alanine aminotransferase test (ALT); aspartate aminotransferase test (AST)] were evaluated using pooled data through week 100 in guselkumab-treated patients receiving and not receiving LTBI treatment. RESULTS: At baseline, 130 randomized patients (guselkumab: n = 69; adalimumab: n = 36; placebo: n = 25) tested positive for LTBI and received concomitant LTBI treatments (LTBI+). No active TB was reported among guselkumab-treated patients without LTBI (LTBI-) through week 100. Two cases of active TB occurred in LTBI- patients treated with adalimumab. Through week 16, across all treatment groups, greater proportions of LTBI+ patients reported ALT and AST elevations compared with LTBI- patients. Through week 100, proportions of patients experiencing AEs and SAEs were comparable between LTBI+ and LTBI- patients. CONCLUSIONS: No cases of active TB, including reactivation of LTBI, were reported in patients with or without LTBI treated with guselkumab through up to 2 years. LTBI treatment was effective across all treatment groups in preventing reactivation of LTBI. Long-term treatment with guselkumab was generally well-tolerated through up to 2 years in patients receiving LTBI medications.

An indirect comparison of long-term efficacy of every-2-week dosing vs. recommended dosing of ixekizumab in patients who had static Physician's Global Assessment > 1 at week 12.

BACKGROUND: Long-term efficacy and safety of ixekizumab [160 mg at week 0, then 80 mg every 2 weeks (Q2W) for 12 weeks, followed by every 4 weeks (Q4W) thereafter (i.e. Q2W/Q4W), which is the labelled psoriasis dosing where approved, except in Japan] have been established for the treatment of adults with moderate-to-severe plaque psoriasis. However, some patients may benefit from remaining on Q2W dosing beyond 12 weeks. METHODS: Among patients who had static Physician's Global Assessment (sPGA) > 1 at week 12, efficacy through week 52 of continuous Q2W dosing in the IXORA-P study was compared indirectly with Q2W/Q4W in the integrated data from the UNCOVER-1, UNCOVER-2 and UNCOVER-3 studies. The continuous Q4W dose group, which had comparable results across studies, was used as the common comparator. RESULTS: In the IXORA-P study, among patients with sPGA > 1 at week 12, 64% of patients in the continuous Q2W group achieved sPGA ≤ 1 at week 52, which was statistically significantly higher than the 36% of patients with sPGA > 1 in the Q2W/Q4W group based on the integrated data from the UNCOVER studies (P = 0·0007). There were no clinically meaningful differences in frequencies of safety events between patients with sPGA ≤ 1 and patients with sPGA > 1 at week 12 in the IXORA-P study. CONCLUSIONS: Among patients who did not have clear or almost clear skin at week 12, nearly 30% more patients who were treated continuously with ixekizumab Q2W in IXORA-P had clear or almost clear skin at week 52 when compared indirectly with those who were treated using the labelled psoriasis dosing in integrated UNCOVER studies. What's already known about this topic? Most patients with moderate-to-severe psoriasis who were given the labelled psoriasis dosing of ixekizumab [160-mg loading dose at week 0, 80 mg every 2 weeks (Q2W) through week 12, and 80 mg every 4 weeks (QW4) thereafter] respond quickly with a high percentage of skin clearance. Additionally, patients who achieve static Physician's Global Assessment (sPGA) ≤ 1 by week 12 tend to maintain this response, even after switching to Q4W. What does this study add? Here, we assessed whether patients with sPGA > 1 at week 12 benefited from receiving more frequent dosing beyond the first 12 weeks. The results showed that Q2W dosing beyond 12 weeks resulted in more patients achieving sPGA ≤ 1 by week 52 than the labelled psoriasis dosing among patients with sPGA > 1 at week 12.

Efficacy and safety of tildrakizumab for plaque psoriasis with continuous dosing, treatment interruption, dose adjustments and switching from etanercept: results from phase III studies.

BACKGROUND: Chronic psoriasis may require medication adjustments over time. OBJECTIVES: To evaluate the efficacy/safety of tildrakizumab in subgroups from the reSURFACE studies (N = 1862) that received continuous dosing, higher/lower dosing, treatment interruption/reinitiation and initiation. METHODS: Responders [Psoriasis Area and Severity Index (PASI) ≥ 75%] and partial responders (PASI ≥ 50% to < 75%) in Part 3 of the reSURFACE studies (weeks 28-52 or week 64) who received tildrakizumab 200 mg or 100 mg were rerandomized to the same dosage (T100/T100 or T200/T200), a higher/lower dosage (T100/T200 or T200/T100) or placebo (PBO) (T100/PBO or T200/PBO). Patients receiving PBO who relapsed were reinitiated to tildrakizumab. Etanercept (ETN) week-28 partial responders and nonresponders (PASI < 50%) received tildrakizumab 200 mg (ETN/T200). RESULTS: Among T100/T100 and T200/T200 week-28 partial responders, the proportion of patients who achieved as-observed PASI 75 responses increased over time. Among T100/T200 week-28 partial responders, PASI 75 responses increased from week 32 (38·5%) to week 52 (63·2%) and remained consistent in T200/T100 week-28 responders. Among patients who relapsed in the T100/PBO and T200/PBO groups, 86% and 83% of those who reinitiated tildrakizumab achieved PASI 75 by week 64, respectively. Among ETN/T200 week-28 partial responders, PASI 75 responses (nonresponder imputation) increased from week 32 (24·1%) to week 52 (74·7%). PASI 90, PASI 100 and Physician's Global Assessment responses were consistent with PASI 75 results. Treatment was well tolerated. CONCLUSIONS: Patients generally fared well with tildrakizumab maintenance, reinitiation, dose adjustment or initiation. What's already known about this topic? Tildrakizumab demonstrated significant efficacy vs. placebo with a positive safety profile during the first 28 weeks of treatment in two randomized double-blind trials. What does this study add? Treatment scenarios with tildrakizumab, such as long-term continuous dosing (up to 64 weeks), treatment interruption/reinitiation and switching from another biologic, can be part of the management of plaque psoriasis with a reasonable expectation of efficacy and tolerability.

Tildrakizumab efficacy and impact on quality of life up to 52 weeks in patients with moderate-to-severe psoriasis: a pooled analysis of two randomized controlled trials.

BACKGROUND: Two randomized controlled trials (reSURFACE 1 and 2) have demonstrated the effectiveness of tildrakizumab, a high-affinity, humanized, IgG1κ, anti-interleukin-23 monoclonal antibody, for treating moderate-to-severe plaque psoriasis in the first 28 weeks. OBJECTIVES: To examine the efficacy of tildrakizumab and its impact on quality of life (QoL) in patients with different levels of week-28 Psoriasis Area and Severity Index (PASI) improvement. METHODS: Patients treated with tildrakizumab 100 mg or 200 mg from baseline to week 28 were pooled from reSURFACE 1 and reSURFACE 2 and classified into five mutually exclusive week-28 PASI improvement groups for each dose: PASI 0-49, 50-74, 75-89, 90-99 and 100. Mean PASI improvement and Dermatology Life Quality Index (DLQI) 0/1 over time were examined for each group. RESULTS: Of 1156 patients, 575 were in the 100-mg and 578 in the 200-mg cohorts, respectively. At week 28, 8.3%, 14.3%, 23.8%, 30.4% and 23.1% in the 100-mg and 4.0%, 18.1%, 19.6%, 29.1% and 29.3% in the 200-mg cohort achieved PASI < 50, 50-74, 75-89, 90-99 and 100, respectively. Patients with PASI < 50 at week 28 could be identified as early as week 8, and those with week-28 PASI ≥ 90 had approximately 50% PASI improvement by week 4. Among patients achieving PASI > 50 at week 28 who continued the same dose of tildrakizumab to week 52, mean PASI improvement was maintained or improved over time. Similar results were observed for both doses. Higher proportions of patients achieved DLQI 0/1 in higher week-28 PASI groups, and DLQI 0/1 was maintained or improved to week 52. However, not all patients with PASI 100 had DLQI 0/1. CONCLUSION: Patients unlikely to respond to tildrakizumab could be identified by week 8, and those likely to achieve a PASI ≥ 90 response could be identified as early as week 4. Week-28 PASI improvement level correlated with QoL improvement.

Efficacy of tildrakizumab for moderate-to-severe plaque psoriasis: pooled analysis of three randomized controlled trials at weeks 12 and 28.

BACKGROUND: Efficacy of tildrakizumab for plaque psoriasis was demonstrated in randomized, placebo-controlled trials. OBJECTIVE: To consolidate tildrakizumab efficacy results by pooling data. METHODS: Data (N = 2081) from tildrakizumab 100 mg, tildrakizumab 200 mg and placebo groups in three trials were pooled. RESULTS: Proportions of Psoriasis Area and Severity Index (PASI) 75 responders at week 12 were better with tildrakizumab 100 mg (62.3%) and tildrakizumab 200 mg (64.8%) vs. placebo (5.6%; P < 0.0001) and for PASI 90, PASI 100 and Physician's Global Assessment (PGA) 'clear' or 'minimal' vs. placebo (P < 0.0001). Responses increased from weeks 12 to 28. Week 12 PASI and PGA responses to tildrakizumab vs. placebo were numerically greater in patients with lower vs. higher bodyweight and were better with tildrakizumab 200 mg than tildrakizumab 100 mg for patients with higher bodyweight. Week 12 PASI 75 responses vs. placebo with tildrakizumab 100 mg were similar between patients with (55.0%) or without (56.7%) prior biologics. PASI 90, PASI 100 and PGA responses were generally higher in patients without prior biologics. Week 8 PASI 50 response predicted PASI 90 response. CONCLUSION: Pooled data confirmed the efficacy of tildrakizumab for moderate-to-severe plaque psoriasis.
