BackgroundContinuous treatment is recommended for patients with moderate-to-severe psoriasis; however, treatment may need to be interrupted in routine clinical practice.ObjectiveTo assess outcomes in patients continuously treated with ixekizumab versus those who interrupted therapy and were subsequently retreated with ixekizumab (IXE).MethodsThis analysis used data pooled from two phase 3 trials, UNCOVER-1 and UNCOVER-2. Patients were randomized to placebo (PBO), IXE every 4 (Q4W) or IXE every 2 weeks (Q2W) for 12 weeks. Patients with a static Physician's Global Assessment (sPGA) 0, 1 at Week 12 were rerandomized to IXEQ4W, IXE every 12 weeks (not presented) or PBO. We examined outcomes in patients who were continuously treated (IXEQ2W/IXEQ4W; IXEQ4W/IXEQ4W) or withdrawn (IXEQ2W/PBO; IXEQ4W/PBO), and in patients who were withdrawn and retreated with IXEQ4W for 24 weeks after disease relapse (sPGA ≥3).ResultsA total of 1226 treated patients achieved an sPGA 0, 1 at Week 12 and entered the maintenance phase; of these patients, 402 and 416 were rerandomized to PBO and IXEQ4W, respectively. Among patients interrupting treatment, 157 (82.2%) of IXEQ4W/PBO and 176 (83.4%) of IXEQ2W/PBO had an sPGA ≥3 by Week 60; median time to relapse was approximately 20 weeks irrespective of induction dose. At Week 60, continuously treated patients maintained high levels of PASI and sPGA responses (90.0% PASI 75 IXEQ2W/IXEQ4W; 81.9% sPGA 0, 1 IXEQ2W/IXEQ4W, non-responder imputation). After 24 weeks of retreatment with IXEQ4W (IXEQ2W/PBO/IXEQ4W and IXEQ4W/PBO/IXEQ4W), 87.0% (107 of 123) and 95.1% (97 of 102) (observed), respectively, of patients recaptured PASI 75 and 70.7% (104 of 147) and 82.3% (107 of 130) (observed) recaptured an sPGA 0, 1. Overall, adverse events in continuously treated and retreated patients were comparable.ConclusionHigh levels of response were sustained with continuous ixekizumab treatment through 60 weeks. Most patients who were withdrawn experienced disease relapse, and most of those patients recaptured response after 24 weeks of retreatment.

Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this fifth of 6 sections of the guidelines of care for psoriasis, we discuss the use of ultraviolet (UV) light therapy for the treatment of patients with psoriasis. Treatment should be tailored to meet individual patients' needs. We will discuss in detail the efficacy and safety as well as offer recommendations for the use of phototherapy, including narrowband and broadband UVB and photochemotherapy using psoralen plus UVA, alone and in combination with topical and systemic agents. We will also discuss the available data for the use of the excimer laser in the targeted treatment of psoriasis. Finally, where available, we will summarize the available data that compare the safety and efficacy of the different forms of UV light therapy. [ABSTRACT FROM AUTHOR]

Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this first of 5 sections of the guidelines of care for psoriasis, we discuss the classification of psoriasis; associated comorbidities including autoimmune diseases, cardiovascular risk, psychiatric/psychologic issues, and cancer risk; along with assessment tools for skin disease and quality-of-life issues. Finally, we will discuss the safety and efficacy of the biologic treatments used to treat patients with psoriasis. [ABSTRACT FROM AUTHOR]

Background: Psoriasis symptoms have a significant negative impact on health-related quality of life, impairing physical functioning and well-being. Objective: To evaluate the impact of brodalumab, a human anti-interleukin-17R monoclonal antibody, on psoriasis symptom severity as measured by a novel patient-reported outcome measure, the Psoriasis Symptom Inventory, and dermatology-specific health-related quality of life as measured by the Dermatology Life Quality Index (DLQI). Methods: This was a secondary analysis of a phase II, randomized, double-blind, placebo-controlled clinical study of patients with moderate-to-severe psoriasis (n = 198) treated with brodalumab or placebo. This analysis assessed Psoriasis Symptom Inventory scores and DLQI scores over time. Analyses were conducted on all patients who were randomized and received one or more injections of the study drug according to intention to treat using last observation carried forward to impute missing data. Results: At week 12, subjects in the brodalumab groups had significant improvements in mean Psoriasis Symptom Inventory total scores [8·5 (70 mg), 15·8 (140 mg), 16·2 (210 mg) and 12·7 (280 mg)] compared with placebo (4·8). Mean improvements in DLQI were clinically meaningful (≥ 5·7) in the brodalumab groups (6·2, 9·1, 9·6 and 7·1, respectively) and significantly greater than placebo (3·1). Improvements in Psoriasis Symptom Inventory were observed as early as week 2 and in DLQI by week 4. All eight Psoriasis Symptom Inventory item scores improved significantly among the brodalumab groups by week 12. Conclusions: Results were from a single randomized clinical trial and may not generalize to broader patient populations. However, treatment with brodalumab provided significant improvement in psoriasis symptoms in patients with moderate-to-severe psoriasis.

Introduction: Treating plaque psoriasis (PsO) with guselkumab (GUS) promotes skin clearance and is associated with improvements in health-related quality of life (HRQoL), anxiety, and depression. It is unclear whether improvements in patient-reported outcomes are due to resolution of skin symptoms or the direct result of GUS treatment., Methods: Two phase 3, placebo- and active-comparator-controlled studies randomized patients with moderate-to-severe PsO to GUS, placebo (crossing over to GUS at week 16), or adalimumab. Post hoc mediation analyses examined direct and indirect effects of GUS, versus adalimumab, on Dermatology Life Quality Index (DLQI) or Hospital Anxiety and Depression Scale (HADS) after adjusting for indirect effects mediated by skin clearance, evaluated via Psoriasis Area and Severity Index (PASI), to determine the direct effect of GUS on dermatology HRQoL, depression, and anxiety., Results: Compared with adalimumab, the natural direct effect (NDE) of GUS on change in DLQI from baseline was - 2.04 (P < 0.001), using PASI improvement as a mediator, indicating 89.2% of the total treatment effect was due to direct effects of GUS; using PASI 90 as a mediator, NDE of GUS was - 1.43 (P < 0.001), with 62.2% of the total treatment effect attributed to direct effects of GUS. Compared with adalimumab, 25.5% of change in HADS anxiety score was mediated through PASI improvement (NDE - 0.74; P = 0.002), indicating 74.5% of the total effect was independent of PASI improvement. Similarly, 24% of treatment effect was mediated through PASI 90 (NDE - 0.76; P = 0.002). Comparable proportions of the total improvement in HADS depression scores were due to direct and indirect effects of GUS mediated through PASI improvement (direct, 50.2%; indirect, 49.8%) or PASI 90 (direct, 59.5%; indirect, 40.5%)., Conclusions: GUS-mediated improvements in anxiety, depression, and overall HRQoL are not solely mediated by resolution of PsO signs, suggesting GUS use has a potential direct effect on anxiety and depression., (© 2024.

Introduction: Risankizumab has demonstrated a favourable safety profile in patients with psoriatic disease (moderate-to-severe psoriasis [PsO] and psoriatic arthritis [PsA]). We evaluated the long-term safety of risankizumab in psoriatic disease., Methods: Long-term safety was evaluated by analysing data from 20 (phase 1-4) clinical trials for plaque PsO and four (phase 2-3) trials for PsA. Treatment-emergent adverse events (TEAEs) and AEs in areas of special interest were reported among patients receiving ≥ 1 dose of risankizumab. Exposure-adjusted event rates were presented as events (E) per 100 patient-years (PY)., Results: The long-term safety data analyses included 3658 patients with PsO (13,329.3 PY) and 1542 patients with PsA (3803.0 PY). The median (range) treatment duration for patients with PsO and PsA was 4.1 (0.2-8.8) years and 2.8 (0.2-4.0) years, respectively. In the PsO population, rates of TEAEs, serious AEs and AEs leading to discontinuation were 145.5 E/100 PY, 7.4 E/100 PY and 1.9 E/100 PY, respectively; in the PsA population, these rates were 142.6 E/100 PY, 8.6 E/100 PY, and 1.8 E/100 PY, respectively. The rates of serious infections (excluding COVID-19-related infections) in the PsO and PsA populations were 1.2 and 1.4 E/100 PY, respectively. The rates of opportunistic infections (excluding tuberculosis and herpes zoster) were low (< 0.1 E/100 PY) in both populations. The rates of both nonmelanoma skin cancer (NMSC) and malignant tumours excluding NMSC were 0.6 and 0.5 E/100 PY in PsO and PsA, respectively, which are within the benchmarks of prior epidemiological studies. Adjudicated major cardiovascular event rates were 0.5 E/100 PY in PsO and 0.3 E/100 PY in PsA, which are within the epidemiologic reference benchmarks for both indications. No additional safety concerns were identified with this long-term exposure., Conclusions: The results support the favourable safety profile of risankizumab for long-term treatment of psoriatic disease with no new safety concerns and similar safety profiles among both PsO and PsA populations., (© 2024.

With the continued development of biologics for the treatment of psoriasis, some patients have achieved optimal control, but a recommended biologic sequence if a biologic fails to initially improve the skin, termed primary nonresponse, or loses efficacy after initial improvement, termed secondary nonresponse, is still lacking. Primary and secondary nonresponse can occur with any class of biologics, and the type of nonresponse can drive the choice of whether to switch within a biologic class or to a different biologic class. The choice of biologic can also be challenging when managing psoriasis and concomitant psoriatic arthritis, as treatment differs on the basis of the severity of both diseases and further classification of axial and peripheral joint involvement. When choosing a biologic, each patient's comorbidities and preferences are also taken into account to provide the optimal therapy. With this lack of an established biologic sequence after biologic failure, the objective of our review is to define a therapy sequence for the tumor necrosis factor (TNF), interleukin-17 (IL-17), and interleukin-23 (IL-23) inhibitor classes in the treatment of psoriasis and psoriatic arthritis. Our proposed biologic sequence was derived through an analysis of the efficacy of each biologic class, primary and secondary nonresponse rates from clinical trials, and clinical experience with expert opinion., (© 2024.

Introduction: Deucravacitinib, a novel, oral, selective allosteric tyrosine kinase 2 inhibitor, demonstrated superiority versus placebo and apremilast in the POETYK PSO-1 and PSO-2 studies. We describe patient-reported outcomes with deucravacitinib treatment versus placebo and apremilast in these studies., Methods: Two multicenter, global, double-blind, placebo- and active comparator-controlled studies randomized patients with moderate-to-severe plaque psoriasis 1:2:1 to placebo, deucravacitinib 6 mg once daily, or apremilast 30 mg twice daily. Score changes from baseline and meaningful within-patient change responses for Psoriasis Symptoms and Signs Diary (PSSD) and Dermatology Life Quality Index (DLQI) were assessed., Results: In POETYK PSO-1 (n = 666) and PSO-2 (n = 1020), respectively, improvement from baseline in PSSD total score was greater with deucravacitinib (- 27.8 and - 30.1) versus placebo (- 4.4 and - 5.9) and apremilast (- 18.9 and - 22.5) at Week 16 and versus apremilast at Week 24 (deucravacitinib: - 32.8 and - 30.7; apremilast: - 21.6 and - 22.8) (nominal p < 0.0001). Improvement from baseline in DLQI score was also greater with deucravacitinib (- 8.5 and - 7.6) versus placebo (- 3.3 and - 3.0) and apremilast (- 5.9 and - 5.8) at Week 16 and versus apremilast at Week 24 (deucravacitinib: - 8.6 and - 7.5; apremilast: - 5.6 and - 5.5) (nominal p < 0.0001). Achievement of meaningful within-patient change in PSSD total score and in DLQI score occurred more frequently with deucravacitinib than placebo and apremilast at Week 16 and versus apremilast at Week 24., Conclusions: Deucravacitinib demonstrated meaningful improvements in patient-reported outcomes in patients with moderate-to-severe plaque psoriasis compared with apremilast and placebo., Clinical Trial Registration: NCT03624127, NCT03611751., (© 2024.

Background: Two phase 3 trials, POETYK PSO-1 and PSO-2, previously established the efficacy and overall safety of deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor, in plaque psoriasis., Objectives: To further assess the safety of deucravacitinib over 52 weeks in the pooled population from these two trials., Methods: Pooled safety data were evaluated from PSO-1 and PSO-2 in which patients with moderate-to-severe plaque psoriasis were randomized 1:2:1 to receive oral placebo, deucravacitinib or apremilast., Results: A total of 1683 patients were included in the pooled analysis. Adverse event (AE) incidence rates were similar in each treatment group, serious AEs were low and balanced across groups, and discontinuation rates were lower with deucravacitinib versus placebo or apremilast. No new safety signals emerged with longer deucravacitinib treatment. Exposure-adjusted incidence rates of AEs of interest with placebo, deucravacitinib and apremilast, respectively, were as follows: serious infections (0.8/100 person-years [PY], 1.7/100 PY, and 1.8/100 PY), major adverse cardiovascular events (1.2/100 PY, 0.3/100 PY, and 0.9/100 PY), venous thromboembolic events (0, 0.2/100 PY, and 0), malignancies (0, 1.0/100 PY and 0.9/100 PY), herpes zoster (0.4/100 PY, 0.8/100 PY, and 0), acne (0.4/100 PY, 2.9/100 PY, and 0) and folliculitis (0, 2.8/100 PY, and 0.9/100 PY). No clinically meaningful changes from baseline in mean levels, or shifts from baseline to CTCAE grade ≥3 abnormalities, were reported in laboratory parameters with deucravacitinib., Conclusions: Deucravacitinib was well-tolerated with acceptable safety over 52 weeks in patients with psoriasis., (© 2024 The Authors.

Background: Patients with psoriasis require long-term management; therefore, understanding the long-term safety of new treatments, such as bimekizumab (BKZ), is crucial., Objectives: To evaluate BKZ's 3-year safety profile in patients with moderate-to-severe plaque psoriasis., Methods: Three years of safety data were pooled from three phase III trials (BE VIVID, BE READY and BE SURE) and their ongoing open-label extension (BE BRIGHT). Treatment-emergent adverse events (TEAEs) are reported using exposure-adjusted incidence rates (EAIRs) per 100 patient-years (PY)., Results: In total, 1495 patients received at least one BKZ dose; total BKZ exposure was 3876.4 PY. The overall EAIR of TEAEs was 175.5/100 PY and decreased with longer exposure to BKZ. The most commonly reported TEAEs were nasopharyngitis, oral candidiasis and upper respiratory tract infection (EAIRs of 15.0/100 PY, 10.1/100 PY and 6.5/100 PY, respectively); 99.3% of oral candidiasis events were mild or moderate in severity, none were serious and few led to discontinuation. EAIRs of other TEAEs of interest were low, including serious infections (1.2/100 PY), adjudicated inflammatory bowel disease (0.2/100 PY) and laboratory elevations in aspartate aminotransferase or alanine aminotransferase (> 5 × upper limit of normal: 0.6/100 PY)., Conclusions: In these analyses pooled across 3 years, no new safety signals were observed with longer exposure to BKZ. The vast majority of oral candidiasis events were mild or moderate in severity, as reported previously., (© The Author(s) 2023.

For decades, topical corticosteroids have been the mainstay of treatment for mild-to-moderate inflammatory skin diseases, even though only short-term use is approved for these agents and systemic inflammation is not addressed. Increased understanding of the immunopathogenesis of these conditions, especially for psoriasis and atopic dermatitis, has facilitated the development of antibody-based drugs that neutralize single key cytokines or their associated receptors, such as interleukin (IL)-17A/F, IL-23, and IL-17RA in psoriasis and IL-13 and IL-4Rα in atopic dermatitis. However, oral therapy is still preferred by many patients owing to the ease of use and needle-free administration. Phosphodiesterase 4 (PDE4) inhibitors have been approved for both oral and topical use for inflammatory skin diseases. In this review, we present a summary of an emerging class of selective PDE4B/D inhibitors under clinical development and compare the differences in selectivity of this new generation of PDE4 inhibitors with the less selective currently approved PDE4 inhibitors., (© 2023.

Background: Spesolimab is an anti-interleukin-36 receptor monoclonal antibody approved to treat generalised pustular psoriasis (GPP) flares. We aimed to assess the efficacy and safety of spesolimab for GPP flare prevention., Methods: This multicentre, randomised, placebo-controlled, phase 2b trial was done at 60 hospitals and clinics in 20 countries. Eligible study participants were aged between 12 and 75 years with a documented history of GPP as per the European Rare and Severe Psoriasis Expert Network criteria, with a history of at least two past GPP flares, and a GPP Physician Global Assessment (GPPGA) score of 0 or 1 at screening and random assignment. Patients were randomly assigned (1:1:1:1) to receive subcutaneous placebo, subcutaneous low-dose spesolimab (300 mg loading dose followed by 150 mg every 12 weeks), subcutaneous medium-dose spesolimab (600 mg loading dose followed by 300 mg every 12 weeks), or subcutaneous high-dose spesolimab (600 mg loading dose followed by 300 mg every 4 weeks) over 48 weeks. The primary objective was to demonstrate a non-flat dose-response curve on the primary endpoint, time to first GPP flare., Findings: From June 8, 2020, to Nov 23, 2022, 157 patients were screened, of whom 123 were randomly assigned. 92 were assigned to receive spesolimab (30 high dose, 31 medium dose, and 31 low dose) and 31 to placebo. All patients were either Asian (79 [64%] of 123) or White (44 [36%]). Patient groups were similar in sex distribution (76 [62%] female and 47 [38%] male), age (mean 40·4 years, SD 15·8), and GPP Physician Global Assessment score. A non-flat dose-response relationship was established on the primary endpoint. By week 48, 35 patients had GPP flares; seven (23%) of 31 patients in the low-dose spesolimab group, nine (29%) of 31 patients in the medium-dose spesolimab group, three (10%) of 30 patients in the high-dose spesolimab group, and 16 (52%) of 31 patients in the placebo group. High-dose spesolimab was significantly superior versus placebo on the primary outcome of time to GPP flare (hazard ratio [HR]=0·16, 95% CI 0·05-0·54; p=0·0005) endpoint. HRs were 0·35 (95% CI 0·14-0·86, nominal p=0·0057) in the low-dose spesolimab group and 0·47 (0·21-1·06, p=0·027) in the medium-dose spesolimab group. We established a non-flat dose-response relationship for spesolimab compared with placebo, with statistically significant p values for each predefined model (linear p=0·0022, emax1 p=0·0024, emax2 p=0·0023, and exponential p=0·0034). Infection rates were similar across treatment arms; there were no deaths and no hypersensitivity reactions leading to discontinuation., Interpretation: High-dose spesolimab was superior to placebo in GPP flare prevention, significantly reducing the risk of a GPP flare and flare occurrence over 48 weeks. Given the chronic nature of GPP, a treatment for flare prevention is a significant shift in the clinical approach, and could ultimately lead to improvements in patient morbidity and quality of life., Funding: Boehringer Ingelheim., Competing Interests: Declaration of interests AM reports consulting fees from AbbVie, Boehringer Ingelheim, Nichi-Iko, Nippon Kayaku, and Novartis; grant support from AbbVie, Eisai, Kyowa Kirin, LEO Pharma, Maruho, Mitsubishi Tanabe, Sun Pharmaceutical Industries, Torii Pharmaceutical, and Taiho Pharmaceutical; and honoraria from AbbVie, Eli Lilly Japan, Eisai, Janssen, Kyowa Kirin, Maruho, Mitsubishi Tanabe, Novartis, Pfizer Japan, Sun Pharmaceutical Industries, Taiho Pharmaceutical, Torii Pharmaceutical, and UCB Japan; and declares advisory board participation for Bristol Myers Squibb, Eli Lilly Japan, GlaxoSmithKline, Kyowa Kirin, Pfizer Japan, and UCB Japan.

Methotrexate (MTX) is a readily accessible drug, first used in 1948 and employed for a wide variety of indications since then. However, despite widespread off-label use, FDA labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata, among others. Without published treatment guidelines, some clinicians may be hesitant to use MTX off-label, or uncomfortable prescribing MTX in this population. To address this unmet need, an expert consensus committee was convened to develop evidence- and consensus-based guidelines for use of MTX to treat pediatric inflammatory skin disease. Clinicians with experience and expertise in clinical research, drug development, and treating inflammatory skin disease in pediatric patients with MTX were recruited. Five committees were created based on major topic areas: (1) indications and contraindications, (2) dosing, (3) interactions with immunizations and medications, (4) adverse effects (potential for and management of), and (5) monitoring needs. Pertinent questions were generated and addressed by the relevant committee. The entire group participated in a modified Delphi process to establish agreement on recommendations for each question. The committee developed 46 evidence- and consensus-based recommendations, each with >70% agreement among members, across all five topics. These are presented in tables and text, along with a discussion of supporting literature, and level of evidence. These evidence- and consensus-based recommendations will support safe and effective use of MTX for the underserved population of pediatric patients who may benefit from this valuable, time-honored medication., (© 2023 The Authors.

What Is This Summary About?: This is a summary of a paper published in a medical journal that describes the results of a study called POETYK PSO-2, which investigated a new treatment for plaque psoriasis. Plaque psoriasis appears on the body as dry, discolored, patches of skin that can be flaky and covered in scales. This can make the skin itch, crack or bleed and make it difficult for people with psoriasis to perform basic everyday tasks. Treatments are available, but some do not always reduce symptoms or may need to be injected or taken multiple times a day, which can be difficult to do, or can have undesirable side effects. Researchers are looking for new treatments for psoriasis., What Happened in the Study?: Deucravacitinib is a once-daily pill taken by mouth (orally) that was studied as a treatment for moderate to severe plaque psoriasis in two large studies conducted globally, PSO-1 and PSO-2. POETYK PSO-2 was a Phase 3 research study, which is a study that tests a treatment in a large group of participants, that looked at how well deucravacitinib worked in participants with moderate to severe plaque psoriasis compared to a placebo (an inactive pill that has no effect) and an approved psoriasis treatment called apremilast, which is a pill taken twice a day. These medications were tested in adults with moderate to severe plaque psoriasis, which is psoriasis involving 10% or more of their body (equal to 10 or more handprints). The aims of the POETYK PSO-2 study were to find out if treatment with deucravacitinib could improve psoriasis for the participants in the study and to see if there were any side effects. Side effects are events that happened during treatment that may or may not be caused by that treatment. The study also wanted to find out what would happen after stopping treatment with deucravacitinib in participants who had shown major improvements in their psoriasis., What Do the Results of the Poetyk Pso-2 Study Show?: After 4 months of treatment, more participants taking deucravacitinib had significantly greater improvements in psoriasis than those taking placebo or apremilast. The study also showed that participants continued to see these improvements after taking deucravacitinib for up to 1 year. Some participants maintained the improvements in their psoriasis with deucravacitinib after stopping treatment and switching to a placebo. Side effects for participants taking deucravacitinib were generally mild and occurred in similar numbers to those in participants taking placebo. The most common side effects in participants taking deucravacitinib were inflammation of the nose and throat (a common cold) which occurred at a similar rate in participants who took placebo. Clinical Trial Registration: NCT03611751 (POETYK PSO-2 study) (ClinicalTrials.gov).

Background: Deucravacitinib, an oral, selective, allosteric tyrosine kinase 2 inhibitor, inhibits cytokine signaling in psoriasis pathogenesis., Objective: The objective of this study was to demonstrate deucravacitinib superiority versus placebo and apremilast in moderate to severe plaque psoriasis based on ≥75% reduction from baseline in Psoriasis Area and Severity Index and a static Physician's Global Assessment score of 0 (clear) or 1 (almost clear) with a ≥2-point improvement from baseline at week 16., Methods: POETYK psoriasis second trial (NCT03611751), a 52-week, double-blinded, phase 3 trial, randomized patients 2:1:1 to deucravacitinib 6 mg every day (n = 511), placebo (n = 255), or apremilast 30 mg twice a day (n = 254)., Results: At week 16, significantly more deucravacitinib-treated patients versus placebo and apremilast patients achieved ≥75% reduction from baseline in Psoriasis Area and Severity Index (53.0% vs 9.4% and 39.8%; P < .0001 vs placebo; P = .0004 vs apremilast) and static Physician's Global Assessment score of 0 or 1 (49.5% vs 8.6% and 33.9%; P < .0001 for both). Efficacy was maintained until week 52 with continuous deucravacitinib. The most frequent adverse event with deucravacitinib was nasopharyngitis. Serious adverse events and discontinuations due to adverse events were infrequent. No clinically meaningful changes were observed in laboratory parameters., Limitations: The study duration was 1 year., Conclusion: Deucravacitinib demonstrated superiority versus placebo and apremilast and was well tolerated in adults with moderate to severe plaque psoriasis., Competing Interests: Conflicts of interest Dr Strober has served as a consultant (honoraria) for AbbVie, Almirall, Amgen, Arcutis, Arena, Aristea, Asana, Boehringer Ingelheim, Bristol Myers Squibb, Connect Biopharma, Dermavant, Eli Lilly, Equillium, GlaxoSmithKline, Immunic Therapeutics, Janssen, Leo Pharma, Maruho, Meiji Seika Pharma, Mindera, Novartis, Ortho Dermatologics, Pfizer, Regeneron, Sanofi Genzyme, Sun Pharma, UCB, Ventyxbio, and vTv Therapeutics; has served as a speaker for AbbVie, Eli Lilly, Janssen, and Sanofi Genzyme; has served as a coscientific director (consulting fee) for CorEvitas' (Corrona) Psoriasis Registry; and has served as an investigator for AbbVie, Cara, CorEvitas' (Corrona) Psoriasis Registry, Dermavant, Dermira, and Novartis.

Background: Psoriasis is a chronic immune-mediated inflammatory skin disease that often leads to a diminished quality of life. Goals of treating patients with psoriasis have shifted with more focus on achieving near or complete clearance of the skin. Guselkumab, a fully human monoclonal antibody targeting interleukin-23, is effective in treating moderate-to-severe psoriasis., Objective: To describe the baseline characteristics of patients with moderate-to-severe psoriasis achieving super-response (Psoriasis Area and Severity Index [PASI] 100 response at Weeks 20 and 28) after commencing guselkumab treatment., Methods: Pooled data from VOYAGE 1 and VOYAGE 2 studies identified super-response; baseline demographic, disease and pharmacokinetic characteristics were compared with non-super-response. A stepwise logistic regression analysis identified which factors were potentially predictive of super-response status, with significance level of 0.1., Results: A subset of patients randomized to guselkumab comprised this post hoc analysis (n = 664); 271 patients achieved super-response vs. 393 with non-super-response. Patient age at study entry and baseline body weight (≤90 kg vs. >90 kg), PASI, and Investigator's Global Assessment (IGA) score were significant predictors of super-response status, with odds ratios (95% confidence intervals) of 0.98 (0.967-0.993; P = 0.003), 1.42 (1.026-1.977; P = 0.034), 0.97 (0.955-0.993; P = 0.007) and 0.66 (0.433-0.997; P = 0.048), respectively. More patients with super-response achieved an early response: Week 2 PASI 75 (5.5% vs. 1.8%) and Week 8 PASI 100 (22.5% vs. 3.3%) vs. non-super-response. Median serum guselkumab concentrations through Week 28 were slightly greater in patients with super-response vs. non-super-response., Conclusion: Guselkumab was more likely to achieve early clinical responses (complete skin clearance) in younger patients, less obese patients and patients with less severe psoriasis., (© 2022 European Academy of Dermatology and Venereology.)

Introduction: Psoriasis is a chronic inflammatory disease that can drastically affect a patient's quality-of-life and is associated with multiple comorbid conditions. The most common form of psoriasis is plaque psoriasis, commonly presenting as sharply demarcated, erythematous plaques with overlying silvery scale on the trunk, extensor surfaces, limbs, and scalp. Although initially limited to oral therapies, the choices in systemic therapies for moderate-to-severe plaque psoriasis have evolved with biologic immunotherapies being the main focus., Areas Covered: In this review, we describe the IL-23/Th17 axis and IL-23 inhibitors as targets for a growing family of biologics. This family includes the FDA-approved medications ustekinumab, guselkumab, tildrakizumab, and risankizumab. We will review the safety and efficacy of these medications throughout various Phase 1,2, and 3, trials for moderate-to-severe psoriasis. A literature search of PubMed was utilized for the following terms: 'psoriasis and IL-23,' 'ustekinumab,' 'guselkumab,' 'tildrakizumab,' and 'risankizumab.' We also searched for clinical trials involving IL-23 inhibitors registered at ClinicalTrials.gov., Expert Opinion: Anti-IL 23 therapy, especially anti-p19 monoclonal antibodies, should be considered first-line therapy for moderate-to-severe plaque psoriasis due to their efficacy and relative safety. More research is required to expand the scope of anti-p19 therapy to pediatric populations and additional indications such as psoriatic arthritis.

Psoriasis is a chronic inflammatory disease that affects up to 1 in 20 people worldwide. A patient's quality of life and health can be drastically affected by psoriasis. The number of therapies for patients with moderate to severe psoriasis has steadily grown over the past two decades, with biologic immunotherapies being the primary agents developed. However, new small-molecule oral therapies have lagged in development. Deucravacitinib is an oral small molecule that inhibits the activity of TYK2, a member of the JAK family. Deucravacitinib works by allosterically inhibiting TYK2, increasing the specificity of this agent for TYK2 rather than other members of this kinase family. Deucravacitinib has demonstrated safety and efficacy in moderate to severe plaque psoriasis in clinical trial development, with >50% of patients on deucravacitinib 6 mg daily achieving ≥75% reduction in Psoriasis Area and Severity Index score from baseline at 16 weeks versus 9-13% on placebo and 35-41% on apremilast 30 mg twice daily in phase III clinical trials.

In squamous cell carcinoma of the larynx, the population of epithelial cells in the tumor tissue is initially heterogeneous and, in addition to tumor cells invading the organ mucosa, includes normal epithelial cells of protein-mucous glands and cells of the stratified epithelium covering the mucous membrane. A search for differential markers to separate these subpopulations was carried out. The surface marker CD44 and cytokeratins 5 and 17 that are often used to verify carcinoma cells, are common markers for all epithelial cells of the larynx. In highly differentiated carcinoma, subpopulations of normal and tumor epithelial cells can be separated by the level of expression of cytokeratins 10 and 18 and nuclear markers Ki-67 and p63. However, in moderately differentiated carcinoma, tumor cells and normal cells of the basal layer of the stratified epithelium covering the mucous membrane of the larynx have similar phenotypes, which should be taken into account when conducting experimental studies., (© 2022.

Importance: Psoriasis is a chronic disease requiring long-term management; understanding the long-term safety profiles of psoriasis treatments, such as bimekizumab, is important., Objective: To evaluate the 2-year safety profile of bimekizumab in patients with moderate to severe plaque psoriasis., Design, Setting, and Participants: Safety data were pooled from a cohort of patients from 4 phase 2 randomized clinical trials (BE ABLE 1, BE ABLE 2, PS0016, and PS0018) and 4 phase 3 randomized clinical trials (BE VIVID, BE READY, BE SURE, and BE BRIGHT) to include 2 years of study treatment. Data were obtained on adults with moderate to severe plaque psoriasis (Psoriasis Area and Severity Index level ≥12, ≥10% body surface area affected by psoriasis, and an Investigator's Global Assessment score ≥3 on a 5-point scale) who were eligible for systemic psoriasis therapy and/or phototherapy., Interventions: Included patients received 1 or more doses of bimekizumab during the phase 2 or phase 3 trials., Main Outcomes and Measures: Treatment-emergent adverse events (TEAEs), serious TEAEs, and TEAEs leading to treatment discontinuation are reported using exposure-adjusted incidence rates (EAIRs) per 100 person-years., Results: A total of 1789 patients (1252 [70.0%] men; mean [SD] age, 45.2 [13.5] years) were treated with 1 or more doses of bimekizumab across the phase 2/3 trials and were included in these analyses; total bimekizumab exposure was 3109.7 person-years. TEAEs occurred at an EAIR of 202.4 per 100 person-years and did not increase with longer duration of bimekizumab exposure. The 3 most frequently reported TEAEs were nasopharyngitis (19.1 per 100 person-years; 95% CI, 17.4-20.9 per 100 person-years), oral candidiasis (12.6 per 100 person-years; 95% CI, 11.3-14.0 per 100 person-years), and upper respiratory tract infection (8.9 per 100 person-years; 95% CI, 7.8-10.1 per 100 person-years). Most oral candidiasis events were mild or moderate; 3 events led to discontinuation. The EAIRs of inflammatory bowel disease (0.1 per 100 person-years; 95% CI, 0.0-0.3 per 100 person-years), adjudicated suicidal ideation and behavior (0.0 per 100 person-years; 95% CI, 0.0-0.2 per 100 person-years), and adjudicated major adverse cardiac events (0.5 per 100 person-years; 95% CI, 0.3-0.8 per 100 person-years) were low., Conclusions and Relevance: In these pooled analyses of data from a cohort of patients from 8 randomized clinical trials, bimekizumab was well tolerated aside from an increased incidence of mild to moderate oral candidiasis. No safety signals were observed compared with previous reports, and there was no increased risk of AEs with longer duration of bimekizumab exposure.

Background: Risankizumab is approved for treatment of moderate to severe plaque psoriasis. Availability of a patient-controlled single self-injection of risankizumab may improve adherence and long-term management of psoriasis., Objective: To investigate efficacy, safety, and usability of a new risankizumab 150 mg/mL formulation administered as a single subcutaneous injection via prefilled syringe (PFS) or autoinjector (AI)., Methods: Efficacy, safety, usability, and acceptability of risankizumab 150 mg/mL PFS or AI were investigated in adults with moderate to severe psoriasis in two phase 3 studies. Study 1 was a multicenter, randomized, double-blinded, placebo-controlled study that investigated 150 mg/mL risankizumab PFS; study 2 was a multicenter, single-arm, open-label study that investigated 150 mg/mL risankizumab AI., Results: At week 16, risankizumab 150 mg/mL demonstrated efficacy vs. placebo (Psoriasis Area and Severity Index ≥90% improvement (PASI 90), 62.9% vs. 3.8%; static Physician Global Assessment (sPGA) 0/1, 78.1% vs. 9.6%; both p < .001) in study 1; in study 2, PASI 90 and sPGA 0/1 were 66.7%, and 81.5%, respectively. All patients successfully self-administered study treatments via PFS or AI. Acceptability of self-injection was high in both studies. Efficacy and safety of risankizumab 150 mg/mL were comparable with results from previous risankizumab phase 3 studies using the 90 mg/mL formulation., Conclusions: The efficacy, safety, and usability of 150 mg/mL risankizumab delivered as a single PFS or AI injection support use of this new formulation in patients with moderate to severe plaque psoriasis., Clinical Trials: NCT03875482 and NCT0387508.

Fast neutron therapy, which previously has demonstrated effective results, but along with a large number of complications, can again be considered a promising treatment method in the treatment of cancer. One of the ways of analyzing the relative biological efficiency and accurate biological dose of fast neutrons in body tissues is to improve the algorithms of computational biology and mathematical modeling. A high-performance computing code was written which allows to estimate in real-time mode the biological dose of the proton component from the action of neutron radiation with an energy of 14.8 MeV. A comparative analysis of the computing performance on various video cards was also performed., (© 2022. Springer Science+Business Media, LLC, part of Springer Nature.)

Background: Risankizumab has demonstrated efficacy and safety in patients with moderate-to-severe plaque psoriasis in randomized clinical trials., Objectives: To evaluate safety data from risankizumab psoriasis phase I-III clinical trials., Methods: Short-term safety (through week 16) was analysed using integrated data from five phase II and III clinical trials. Long-term safety was evaluated using integrated data from 17 phase I-III completed and ongoing trials., Results: Short-term safety analyses included 1306 patients receiving risankizumab 150 mg and 300 patients receiving placebo [402·2 and 92·0 patient-years (PY) of exposure, respectively]. Long-term analyses included 3072 risankizumab-treated patients (exposure: 7927 PY). The median (excluding four outliers) treatment duration was 2·9 years (range 2 days to 5·9 years). Exposure-adjusted adverse event rates did not increase with long-term treatment (318 vs. 171 events per 100 PY for short- and long-term analyses). With long-term risankizumab treatment, rates of serious adverse events were 7·8 per 100 PY, serious infections 1·2 per 100 PY, nonmelanoma skin cancer (NMSC) 0·7 per 100 PY, malignant tumours excluding NMSC 0·5 per 100 PY, and adjudicated major adverse cardiovascular events 0·3 per 100 PY, with no important identified risks. Limitations include that the study inclusion and exclusion criteria varied and that three studies enrolled ≤ 50 patients., Conclusions: Risankizumab demonstrated a favourable safety profile over short- and long-term treatment in patients with moderate-to-severe psoriasis., (© 2021 The Authors.

Introduction: Patients with moderate-to-severe plaque psoriasis who experience poor clinical outcomes, including patients with obesity or prior treatment, need improved treatment options. Risankizumab specifically inhibits interleukin 23 and has demonstrated superior efficacy in active-comparator studies in patients with moderate-to-severe plaque psoriasis. We compared the efficacy of risankizumab with that of secukinumab across patient subgroups., Methods: Subgroup analyses using data from the phase 3 IMMerge study (NCT03478787) were performed. Efficacy in adults with moderate-to-severe psoriasis treated with risankizumab 150 mg and secukinumab 300 mg was assessed as the proportion of patients who achieved ≥ 90% improvement in Psoriasis Area Severity Index (PASI 90) at week 52 across demographics and disease characteristics. Post hoc analyses evaluated the proportion of patients who achieved PASI 90 and the least-squares mean percent PASI improvement from baseline at week 52 by body weight and body mass index (BMI), PASI 90 by prior treatment, and clinical response [PASI 90, PASI 100, and/or static Physician's Global Assessment (sPGA) score of clear (0) or almost clear (1)] at week 16 and maintained particular response at week 52. Logistic regression analyses examined the effect of covariates (age, sex, BMI, baseline PASI, treatment) and potential interactions on PASI 90 at week 52., Results: More patients who received risankizumab (n = 164) compared with secukinumab (n = 163) achieved PASI 90 at week 52, regardless of demographics and disease characteristics (BMI, prior treatment, disease duration, and maintenance of clinical response at week 52). Improvements in PASI were greater in patients taking risankizumab than those taking secukinumab, regardless of weight or BMI. Results from logistic regression analysis showed treatment type had a significant impact on PASI 90 (risankizumab versus secukinumab, p < 0.0001)., Conclusion: Risankizumab showed consistently greater efficacy compared with secukinumab across different patient subgroups, and this was maintained through 52 weeks., Trial Registration: ClinicalTrials.gov identifier; NCT03478787., (© 2022. The Author(s).)

Background: It is unclear whether primary efficacy outcomes in plaque psoriasis clinical trials represent residual disease during treatment., Objectives: To evaluate supplementing dichotomous efficacy with residual disease activity., Methods: This post hoc analysis used pooled, patient-level data after tildrakizumab 100 mg ( N  = 616) or placebo ( N  = 309) treatment from reSURFACE 1/2 (NCT01722331/NCT01729754) phase 3 clinical trials of patients with moderate to severe plaque psoriasis., Results: Median baseline Psoriasis Area and Severity Index (PASI) was 17.9 for patients receiving tildrakizumab 100 mg. At Week 12, median PASI was 2.9, whereas dichotomous PASI 90 response rate was 36.9%, and absolute PASI <5.0, <3.0, and <1.0 were 64.0%, 50.8%, and 23.3%, respectively. At Week 28, median PASI was 1.7, whereas PASI 90 response rate was 51.9%, and absolute PASI <5.0, <3.0, and <1.0 were 75.3%, 62.8%, and 38.0%, respectively. Dermatology Life Quality Index and PASI scores were correlated through Week 28 ( r  = 0.51, p  ≤ .0001)., Conclusions: Disease activity was more reliably estimated by PASI scores than percentage PASI improvement; this may partially explain efficacy disparities between clinical trials and practice. These results suggest supplementing dichotomous PASI improvement with PASI scores and consideration of patient treatment goals could facilitate clinical decisions.

Introduction: Deucravacitinib is an oral, selective tyrosine kinase 2 inhibitor that demonstrated therapeutic benefit in a Phase 2 clinical trial of adults with moderate to severe plaque psoriasis. This analysis was designed to evaluate the effect of deucravacitinib on additional clinical and quality-of-life (QoL) outcomes and assess the relationship between these outcomes in adults with psoriasis., Methods: Post-hoc analysis of a 12-week Phase 2 trial was conducted for the three most efficacious dosage groups (3 mg twice daily, 6 mg twice daily, 12 mg once daily) and placebo. Investigator assessments for efficacy included Psoriasis Area and Severity Index (PASI), body surface area (BSA) involvement, and static Physician's Global Assessment; QoL was assessed using the Dermatology Life Quality Index (DLQI). Treatment responses and their associations were evaluated over time., Results: Deucravacitinib elicited improvement versus placebo as early as Week 4 for most efficacy measures (including changes in absolute PASI and BSA), with efficacy trends observed from Week 2 to Week 12. Improvements in QoL, assessed by achievement of a DLQI overall score of 0/1 (no effect at all on patient's life), followed a pattern similar to deucravacitinib-related clinical outcomes over 12 weeks. Overall, patients with greater improvements in psoriasis-related clinical signs and symptoms also reported greater improvement in QoL. However, complete skin clearance was not required for achieving DLQI 0/1., Conclusion: Deucravacitinib treatment produced early response and similar trends in improvements across multiple efficacy assessments and QoL in moderate to severe plaque psoriasis. Deucravacitinib has the potential to become a promising new oral therapy for this condition., Trial Registration: ClinicalTrials.gov identifier; NCT02931838., (© 2022. The Author(s).)

Background: Psoriasis is a chronic disease requiring long-term therapy., Objectives: Physician- and patient-reported outcomes were evaluated through week 252 in VOYAGE 1 and VOYAGE 2., Methods: In total, 1829 patients were randomized at baseline to receive guselkumab 100 mg every 8 weeks, placebo or adalimumab. Patients receiving placebo crossed over to guselkumab at week 16. Patients receiving adalimumab crossed over to guselkumab at week 52 in VOYAGE 1, and randomized withdrawal and retreatment occurred at weeks 28-76 in VOYAGE 2; all patients then received open-label guselkumab through week 252. Efficacy and health-related quality of life (HRQoL) endpoints were analysed through week 252. Safety was monitored through week 264., Results: The proportions of patients in the guselkumab group who achieved clinical responses at week 252 in VOYAGE 1 and VOYAGE 2, respectively, were 84·1% and 82·0% [≥ 90% improvement in Psoriasis Area and Severity Index (PASI)]; 82·4% and 85·0% [Investigator's Global Assessment (IGA) 0 or 1]; 52·7% and 53·0% (100% improvement in PASI) and 54·7% and 55·5% (IGA 0). HRQoL endpoints were achieved as follows: 72·7% and 71·1% of patients (Dermatology Life Quality Index 0 or 1: no effect on patient's life); 42·4% and 42·0% [Psoriasis Symptoms and Signs Diary (PSSD) symptom score = 0] and 33·0% and 31·0% (PSSD sign score = 0). As measured in VOYAGE 2 only, approximately 45% of patients achieved ≥ 5-point reduction in Short Form-36 physical and mental component scores, and 80% reported no anxiety or depression (Hospital Anxiety and Depression Scale scores < 8). Similar findings were reported for adalimumab crossovers. These effects were maintained from week 52 in VOYAGE 1 and week 100 in VOYAGE 2. No new safety signals were identified., Conclusions: Guselkumab maintains high levels of clinical response and improvement in patient-reported outcomes through 5 years in patients with moderate-to-severe psoriasis., (© 2021 The Authors.

Background: Certolizumab pegol (CZP) is an Fc-free, PEGylated anti-tumour necrosis factor biologic., Objectives: To report the 3-year efficacy of CZP in plaque psoriasis, pooled from the CIMPASI-1 (NCT02326298) and CIMPASI-2 (NCT02326272) phase III trials., Methods: Adults with moderate-to-severe psoriasis for ≥ 6 months were randomized 2 : 2 : 1 to CZP 200 mg, CZP 400 mg or placebo, every 2 weeks (Q2W) for up to 48 weeks. Patients entering the open-label period (weeks 48-144) from double-blinded CZP initially received CZP 200 mg Q2W. Patients not achieving ≥ 50% improvement in Psoriasis Area and Severity Index (PASI 50) at week 16 entered an open-label CZP 400 mg Q2W escape arm (weeks 16-144). Dose adjustments based on PASI response were permitted during open-label treatment. Outcomes included PASI 75, PASI 90 and Physician's Global Assessment (PGA) 0/1 responder rates, based on a logistic regression model (missing data imputed using Markov Chain Monte Carlo methodology)., Results: In total, 186 patients were randomized to CZP 200 mg Q2W and 175 to CZP 400 mg Q2W. At week 48, PASI 75/90 was achieved by 72·7%/51·3% of patients randomized to CZP 200 mg and 84·4%/62·7% randomized to CZP 400 mg. Patients entering the open-label period at week 48, from blinded treatment, received CZP 200 mg Q2W. At week 144, PASI 75/90 was achieved by 70·6%/48·7% patients randomized to CZP 200 mg and 72·9%/42·7% randomized to CZP 400 mg. At week 16, 72 placebo-randomized patients entered the CZP 400 mg Q2W escape arm; 75.7%/58.5% achieved PASI 75/90 at week 144., Conclusions: Both CZP 200 mg and 400 mg Q2W demonstrated sustained, durable efficacy, with numerically higher responses for some outcomes with 400 mg Q2W., (© 2020 The Authors.

Background: Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. This study investigated the efficacy and safety of bimekizumab in patients with moderate to severe plaque psoriasis, the effects of treatment withdrawal, and two maintenance dosing schedules over 56 weeks., Methods: BE READY was a phase 3, multicentre, randomised, double-blind, placebo-controlled trial done at 77 sites (hospitals, clinics, private doctor's practices, and dedicated clinical research centres) in nine countries across Asia, Australia, Europe, and North America. Adult patients aged 18 years or older with moderate to severe plaque psoriasis were stratified by region and previous biologic exposure, and randomly assigned (4:1) to receive bimekizumab 320 mg every 4 weeks or placebo every 4 weeks by use of interactive response technology. Coprimary endpoints were the proportion of patients achieving 90% or greater improvement from baseline in the Psoriasis Area Severity Index (PASI90) and the proportion of patients achieving a score of 0 (clear) or 1 (almost clear) on the five-point Investigator's Global Assessment (IGA) scale at week 16 (non-responder imputation). Bimekizumab-treated patients achieving PASI90 at week 16 were re-allocated (1:1:1) to receive bimekizumab 320 mg every 4 weeks, every 8 weeks, or placebo for weeks 16-56. Efficacy analyses were done in the intention-to-treat population; the safety analysis set comprised all patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov (NCT03410992), and is now completed., Findings: Between Feb 5, 2018, and Jan 7, 2020, 435 patients were randomly assigned to receive either bimekizumab 320 mg every 4 weeks (n=349) or placebo every 4 weeks (n=86). Coprimary endpoints were met: at week 16, 317 (91%) of 349 patients receiving bimekizumab 320 mg every 4 weeks achieved PASI90, compared with one (1%) of 86 patients receiving placebo (risk difference 89·8 [95% CI 86·1-93·4]; p<0·0001); and 323 (93%) of 349 patients receiving bimekizumab 320 mg every 4 weeks achieved an IGA score of 0 or 1 versus one (1%) of 86 patients receiving placebo (risk difference 91·5 [95% CI 88·0-94·9]; p<0·0001). Responses were maintained through to week 56 with bimekizumab 320 mg every 8 weeks and every 4 weeks. Treatment-emergent adverse events in the initial treatment period (up to week 16) were reported in 213 (61%) of 349 patients receiving bimekizumab 320 mg every 4 weeks and 35 (41%) of 86 patients receiving placebo every 4 weeks. From week 16 to week 56, treatment-emergent adverse events were reported in 78 (74%) of 106 patients receiving bimekizumab 320 mg every 4 weeks, 77 (77%) of 100 patients receiving bimekizumab 320 mg every 8 weeks, and 72 (69%) of 105 patients receiving placebo., Interpretation: Bimekizumab showed high levels of response, which were durable over 56 weeks, with both maintenance dosing schedules (every 4 weeks and every 8 weeks). Moreover, bimekizumab was well tolerated, with no unexpected safety findings. Data presented here further support the therapeutic value of bimekizumab and inhibition of IL-17F in addition to IL-17A for patients with moderate to severe plaque psoriasis., Funding: UCB Pharma., (Copyright © 2021 Elsevier Ltd.

Background: There is an unmet need for a treatment for psoriasis that results in complete skin clearance with a reliably quick response. Bimekizumab is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. We aimed to compare the efficacy and safety of bimekizumab with placebo and ustekinumab in patients with moderate to severe plaque psoriasis over 52 weeks., Methods: BE VIVID was a multicentre, randomised, double-blind, active comparator and placebo controlled phase 3 trial done across 105 sites (clinics, hospitals, research units, and private practices) in 11 countries in Asia, Australia, Europe, and North America. Adults aged 18 years or older with moderate to severe plaque psoriasis (Psoriasis Area and Severity Index [PASI] score ≥12, ≥10% body surface area affected by psoriasis, and Investigator's Global Assessment [IGA] score ≥3 on a five point scale) were included. Randomisation was stratified by geographical region and previous exposure to biologics; patients, investigators, and sponsors were masked to treatment assignment. Patients were randomly assigned (4:2:1) using an interactive response technology to bimekizumab 320 mg every 4 weeks, ustekinumab 45 mg or 90 mg (baseline weight-dependent dosing) at weeks 0 and 4, then every 12 weeks, or placebo every 4 weeks. At week 16, patients receiving placebo switched to bimekizumab 320 mg every 4 weeks. All study treatments were administered as two subcutaneous injections. Coprimary endpoints were the proportion of patients with 90% improvement in the PASI (PASI90) and the proportion of patients with an IGA response of clear or almost clear (score 0 or 1) at week 16 (non-responder imputation). Efficacy analyses included the intention-to-treat population; safety analysis included patients who received at least one dose of study treatment. This trial was registered at ClinicalTrials.gov, NCT03370133 (completed)., Findings: Between Dec 6, 2017, and Dec 13, 2019, 735 patients were screened and 567 were enrolled and randomly assigned (bimekizumab 320 mg every 4 weeks n=321, ustekinumab 45 mg or 90 mg every 12 weeks n=163, placebo n=83). At week 16, 273 (85%) of 321 patients in the bimekizumab group had PASI90 versus 81 (50%) of 163 in the ustekinumab group (risk difference 35 [95% CI 27-43]; p<0·0001) and four (5%) of 83 in the placebo group (risk difference 80 [74-86]; p<0·0001). At week 16, 270 (84%) patients in the bimekizumab group had an IGA response versus 87 (53%) in the ustekinumab group (risk difference 30 [95% CI 22-39]; p<0·0001) and four (5%) in the placebo group (risk difference 79 [73-85]; p<0·0001). Over 52 weeks, serious treatment-emergent adverse events were reported in 24 (6%) of 395 patients in the bimekizumab group (including those who switched from placebo at week 16) and 13 (8%) of 163 in the ustekinumab group., Interpretation: Bimekizumab was more efficacious than ustekinumab and placebo in the treatment of moderate to severe plaque psoriasis. The bimekizumab safety profile was consistent with that observed in previous studies., Funding: UCB Pharma., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Proton therapy (PT) due to dosimetric characteristics (Bragg peak formation, sharp dose slowdown) is currently one of the most high-tech techniques of radiation therapy exceeding the standards of photon methods. In recent decades, PT has traditionally been used, primarily, for head and neck cancers (HNC) including skull base tumors. Regardless of the fact that recently PT application area has significantly expanded, HNC still remain a leading indication for proton radiation since PT's physic-dosimetric and radiobiological advantages enable to achieve the best treatment results in these tumors. The present review is devoted to PT usage in HNC treatment in the world and Russian medicine, the prospects for further technique development, the assessment of PT's radiobiological features, a physical and dosimetric comparison of protons photons distribution. The paper shows PT's capabilities in the treatment of skull base tumors, HNC (nasal cavity, paranasal sinuses, nasopharynx, oropharynx, and laryngopharynx, etc.), eye tumors, sialomas. The authors analyze the studies on repeated radiation and provide recent experimental data on favorable profile of proton radiation compared to the conventional radiation therapy. The review enables to conclude that currently PT is a dynamic radiation technique opening up new opportunities for improving therapy of oncology patients, especially those with HNC., Competing Interests: Conflicts of interest.
