Background: Our objective was to describe the clinical, histological characteristics, and disease outcome of a cohort of mycosis fungoides (MF) diagnosed during childhood including disease status at adulthood. Methods: This is a retrospective multicentre survey of patients aged under 18 years at diagnosis with histologically confirmed MF. Patients’ clinical and histological characteristics, treatments, and disease outcome (for patients followed for more than 12 months) were analysed. Results: Forty-six patients were included (median age at diagnosis: 11 years; M:F sex ratio: 3:1) with 39 (85%) followed for at least 12 months. Thirty-nine patients (85%) had stage I MF. Hypopigmented patches were observed in 48% and folliculotropism in 43% patients. Immunophenotype of the skin infiltrate was predominantly CD8+ in 17% of patients. Initial management included a wait-and-see strategy in 6/39 (15%), skin-directed treatment in 27 (69%), and systemic treatment in 6 (15%) patients, respectively, with partial or complete clinical response (PR or CR) observed in 28 patients (72%). 14/39 patients (36%) relapsed after initial response. After a median follow-up period of 54 months, disease status at last news was PR or CR in 31/39 (79%), stable disease in 6 (15%), and progression in 2 (5%) patients. Histological transformation was observed in 3/39 (8%). Of the 15 patients followed until adulthood, 13 (87%) had persistent MF. Discussion: This survey confirms the high frequency of hypopigmented and folliculotropic lesions and of CD8+ immunophenotype compared to adult MF patients. The long-term course is usually indolent but transformation may occur sometimes long after disease onset and the disease may persist during adulthood.

Additional long-term treatments are needed for moderate-to-severe atopic dermatitis (AD). An ongoing, open-label, 5-year extension trial, ECZTEND (NCT03587805), assesses tralokinumab plus optional topical corticosteroids in participants from previous tralokinumab parent trials (PTs) with moderate-to-severe AD.To evaluate the safety and efficacy of up to 2 years tralokinumab treatment in a post hoc interim analysis.Safety analyses included adults from completed PTs enrolled in ECZTEND, regardless of tralokinumab exposure duration. Efficacy analyses included adult participants treated with tralokinumab in ECZTEND for ≥1 year and subgroup analyses of those on tralokinumab for 2 years (1 year from PT, 1 year in ECZTEND). Primary end point was the number of adverse events with additional efficacy end points.Participants on tralokinumab had an exposure-adjusted rate of 237.8 adverse events/100 patient-years' exposure (N = 1174) in the safety analysis set. Exposure-adjusted incidence rates of common adverse events were comparable to PTs, although at lower rates. With 2 years of tralokinumab, improvements in extent and severity of AD were sustained, with Eczema Area and Severity Index (EASI-75) in 82.5% of participants (N = 345).Possible selection bias; no placebo arm; some participants experienced treatment gaps between PTs and ECZTEND.Over 2 years, tralokinumab was well tolerated and maintained long-term control of AD signs and symptoms.

Summary Background Baricitinib, an oral selective Janus kinase (JAK)1 and JAK 2 inhibitor, was shown to improve the signs and symptoms of moderate-to-severe atopic dermatitis (AD). Objectives To evaluate the efficacy and safety of baricitinib with background topical corticosteroids (TCS) in patients with moderate-to-severe AD and inadequate response, intolerance or contraindication to ciclosporin A (CA). Methods In this double-blind, randomized, placebo-controlled, phase III study, patients were randomized 1: 1: 2: 1 to placebo (N = 93), baricitinib 1 mg (N = 93), 2 mg (N = 185) or 4 mg (N = 92) with background TCS. The primary endpoint was the proportion of patients receiving baricitinib 4 mg or 2 mg (+ TCS) vs. placebo + TCS who achieved ≥ 75% improvement from baseline in the Eczema Area and Severity Index (EASI 75) at week 16. Results Baricitinib 4 mg + TCS was superior to placebo + TCS for EASI 75 (4 mg: 32%, placebo: 17%, P = 0·031) at week 16 and for improvements in itch, skin pain and number of night-time awakenings owing to itch. Improvements were maintained through 52 weeks of treatment. Treatment-emergent adverse events (TEAEs) were more common with baricitinib than placebo (+ TCS); most were mild or moderate. The most frequent TEAEs with baricitinib 4 mg + TCS were nasopharyngitis, herpes simplex, influenza and headache. No deaths or deep vein thromboses were reported. Conclusions Baricitinib 4 mg + TCS improved the signs and symptoms of moderate-to-severe AD through 52 weeks of treatment in patients with inadequate response, intolerance or contraindication to CA. The safety profile was consistent with previous studies of baricitinib in moderate-to-severe AD. What is already known about this topic? Ciclosporin A is indicated for the treatment of atopic dermatitis that is refractory to topical therapies. However, its use is limited by safety concerns and it may not provide adequate response for some patients. Baricitinib, an oral selective Janus kinase (JAK)1 and JAK2 inhibitor, has been shown to improve the signs and symptoms of moderate-to-severe atopic dermatitis as a monotherapy or in combination with topical corticosteroids. What does this study add? Baricitinib combined with background low- or moderate-potency topical corticosteroids provided improvements in the signs and symptoms of moderate-to-severe atopic dermatitis through 1 year of treatment in patients with a contraindication, intolerance or failure to respond to ciclosporin A. The most common treatment-emergent adverse events with baricitinib 4 mg were nasopharyngitis, herpes simplex, influenza and headache. The safety profile was consistent with previous studies in patients with moderate-to-severe atopic dermatitis.

BACKGROUND: Psoriasis is a chronic inflammatory skin disorder that affects 125 million people worldwide, with one-third having childhood onset. OBJECTIVES: The PURPOSE study evaluated long-term safety and effectiveness of etanercept in paediatric psoriasis. MATERIALS & METHODS: This observational study enrolled patients with paediatric psoriasis who were prescribed etanercept per routine care in eight EU countries. Patients were followed retrospectively (first dose prior to 30 days before enrolment) or prospectively (first dose within 30 days prior to or any time after enrolment) for five years. Safety endpoints included serious infections, opportunistic infections, malignancies, other serious adverse events (SAEs) and adverse events. Effectiveness endpoints (prospective patients) included treatment patterns, dose change/discontinuation, and physicians' global subjective assessment of change in disease severity from baseline to follow-up. RESULTS: In total, 72 patients were enrolled (32 prospectively, 40 retrospectively), with mean age of 14.5 years and mean disease duration of 7.1 years. No serious or opportunistic infections/malignancies were reported. Psoriasis (n=8) and subcutaneous tissue disorders (system organ class) (erythema nodosum, erythrodermic psoriasis; n=1 for each) were the most frequently reported SAEs, which occurred in six (8.3%) patients with current/recent treatment and four (7.4%) with previous treatment. Of 25 treatment-emergent SAEs, seven (28.0%) were possibly related to etanercept. Assessments of prospective patients revealed that 28 (87.5%) completed 24 weeks, five (15.6%) required at least one subsequent course, and 93.8% experienced decreased disease severity. It is possible that some rare adverse events were not noted in this relatively small sample. CONCLUSION: These real-world data are consistent with the known safety and efficacy profile of etanercept in paediatric patients with moderate to severe plaque psoriasis.

There is currently little information on switching biologics in pediatric psoriasis.To evaluate the real-world clinical practice and safety of switching biologics in the "Biological Treatments for Pediatric Psoriasis" (BiPe) cohort.Data for all 134 patients included in the BiPe cohort were analyzed. A further evaluation of the subpopulation of patients who switched from a first-line biologic to a second-line biologic was then conducted. Drug survival rates were also compared between biologics given as first-line or second-line agents.Overall, 29 patients (female: 55%; mean age: 16.6 ± 3.0 years) switched between two biologics. Etanercept (ETN) was the first-line biologic used in 23 patients: 16 (69.6%) switched to adalimumab (ADA) and seven (30.4%) to ustekinumab (UST). Six patients received first-line ADA and switched to UST. Loss of efficacy (62.1%), primary inefficacy (20.7%), and parental choice (6.9%) were the main reasons for switching biologics. One (3.4%) of the switches was performed because of adverse events or intolerance. For UST and ADA, the 18-month drug survival rate did not differ according to whether the agent was given as a first-line or second-line biologic (UST: P = .24; ADA: P = .68). No significant differences in drug survival rates were observed between the three different switches (ADA to UST, ETN to ADA, and ETN to UST).Our study provided key insights into the real-life clinical practice of switching biologics in pediatric psoriasis patients. However, more information and guidance on switching biologics in pediatric psoriasis are needed to improve real-life practice and outcomes.

BACKGROUND Light-emitting diodes (LEDs) in the visible or near-infrared spectrum have been reported to promote wound healing. However, despite being frequently proposed in daily clinical practice, the efficacy of photobiomodulation treatment after a laser procedure relies on very limited clinical data. OBJECTIVE To compare the relative efficacy of LED versus placebo treatment in decreasing erythema and transepidermal water loss (TEWL) after a fractional CO2 session. METHODS We conducted an open prospective intraindividual randomized controlled study with 10 healthy volunteers. An ablative fractional laser was performed on the seven forearm areas. Three consecutive daily sessions of LED (590, 630, and 850 nm [two tested irradiances each] and placebo) were applied after randomization. Physical measures (colorimetry, TEWL), photography, and clinical evaluation were performed on Days 1, 2, 3, 7, and 21. The main criterion of evaluation was the variation of parameter a* (erythema) at 72 hours for each LED parameter compared to placebo treatment. RESULTS No significant differences in the variation of the parameter a* or any of the other studied parameters were found for the different LEDs compared to the placebo area. CONCLUSION Photobiomodulation failed to improve healing after laser ablation compared to placebo.

Annular lipoatrophy of the ankle is a rare and unique acquired lipoatrophic panniculitis that mainly affects children. There is no consensus on treatment, and the long-term course is not well known. We present four new pediatric cases that contribute to the understanding of this rare disease.

It is important to assess the burden of chronic urticaria (CU) with real-life studies. The AWARE study was performed in 36 countries over two years in CU patients resistant to H1-antihistamines.To correlate patient-reported outcomes and available therapeutic options in CU patients.The AWARE study was a prospective, non-interventional, international study that included adult patients who have had H1-antihistamine-resistant CU for at least two months. The primary endpoints were the evolution of disease activity (UAS7), urticaria control (UCT), dermatological quality of life (DLQI) and treatment satisfaction (visual analogic scale) during a two-year follow-up. The data from French centres are reported.Ninety-two patients were included (mean age: 47.8 years; women: 70.7%; mean disease duration: 6.5 years; angioedema: 34.1%). The percentage of patients with CU treatment increased from 56.5% at inclusion to 86.0% after two years (for patients with non-sedative H1-antihistamines from 52.2% to 74.4%, and omalizumab from 2.2% to 25.6%). During the follow-up, the percentage of patients with UAS7 score6 increased from 12.5% to 60.9%, and patients with well-controlled CU (UCT score12) increased from 11.1% to 62.2%. The negative impact on quality of life (DLQI10) decreased from 34.1% to 10.5%. The mean score of patient satisfaction for treatment increased from 4.6 to 7.6.The management of CU patients resistant to H1-antihistamines was not optimal at inclusion with uncontrolled disease, impaired quality of life and insufficient treatment. After a two-year follow-up, disease symptoms and quality of life improved, but the therapeutic management could be further optimized.

Psoriasis is a chronic disease requiring long-term treatment strategies. Optimal strategies should include initial rapid relief of symptoms followed by long-term management to maintain remission. This 4-week open-label phase of a long-term proactive management phase 3 trial aimed to select responders to once daily, fixed-dose combination calcipotriene 0.005% and betamethasone dipropionate 0.064% (Cal/BD) foam in adults with psoriasis and assess patient-reported outcomes.This phase 3 trial in adults with psoriasis included a 4-week open-label lead-in phase to determine treatment success prior to entering the randomized maintenance phase. Success was defined as Physician Global Assessment (PGA) scorelsquo;clearrsquo;/lsquo;almost clearrsquo; (PGAlt;2) withge;2-grade improvement from baseline. Those achieving treatment success at week 4 entered the maintenance phase; non-responders were withdrawn from the trial.650 patients enrolled in the open-label phase, and 623 were treated with Cal/BD foam for 4 weeks; 521 (80%) patients achieved treatment success and were included in the maintenance phase. In those patients achieving success (responders), 21.1% and 78.9% achieved a PGA score oflsquo;clearrsquo; andlsquo;almost clearrsquo;, respectively. Mean change from baseline in modified Psoriasis Area and Severity Index (plusmn; standard deviation [SD]) and body surface area (plusmn; SD) in responders at week 4 wasminus;82.1% (16.4%) andminus;56.6% (38.3%), respectively. Mean Dermatology Life Quality Index score reduced by 6.0 from baseline to week 4 (n=521). 17.7% of patients experienced AEs; with only one severe AE reported.Cal/BD foam was highly efficacious and well tolerated during the 4-week lead-in phase of PSO-LONG.

Background Psoriasis vulgaris is commonly treated with topical corticosteroids and vitamin D analogues. Although potent and super-potent topical corticosteroids are very effective at clearing psoriasis, with short-term reactive treatment durations, symptoms usually recur after treatment discontinuation, necessitating long-term disease management strategies. A foam formulation of calcipotriol and betamethasone dipropionate (Cal/BD foam), consisting of calcipotriol 50 μg/g and betamethasone dipropionate 0.5 mg/g, is approved for the daily treatment of psoriasis for up to 4 weeks. Here, we describe a clinical trial protocol for evaluating the long-term safety and efficacy of twice-weekly Cal/BD foam as a proactive topical maintenance therapy for plaque psoriasis for up to 52 weeks. Objective The aim of this trial was to evaluate the safety and efficacy of Cal/BD foam when applied twice weekly for up to 52 weeks as proactive maintenance therapy, with the goal of preventing or delaying disease relapse as long as possible while minimizing adverse effects. Methods Once-daily Cal/BD foam treatment responders from an initial 4-week open-label period were randomized to receive Cal/BD foam or foam vehicle applied to previously cleared plaques twice weekly for up to 52 weeks. In case of relapse, affected subjects in either group received rescue therapy with once-daily Cal/BD foam for 4 weeks on active areas. Thus, the trial (NCT02899962) compared the long-term use of Cal/BD foam in a proactive approach with a conventional, reactive approach. Planned Outcomes Efficacy endpoints included the time to first relapse, the number of relapse-free days, and the number of relapses during the maintenance phase. Safety assessments included adverse events, incidence of rebound, local safety and tolerability scores, and effects on calcium metabolism and hypothalamic–pituitary–adrenal axis function.

Introduction Clinical trials have shown that psoriasis patients who achieve complete skin clearance are more likely to report no impairment in health-related quality of life (HRQoL) and no psoriasis symptoms versus patients who achieve almost complete skin clearance. However, real-world data are lacking. The objective of this study was to estimate the real-world proportion of moderate-to-severe psoriasis patients on biologic treatment who achieved a Psoriasis Symptom Inventory (PSI) total score of 0 (PSI 0; no symptoms) and a Dermatology Life Quality Index (DLQI) score of 0/1 (DLQI 0/1; no impact on HRQoL), and to study the relationship between patient-reported symptoms and HRQoL versus physician-reported psoriasis severity (Psoriasis Area and Severity Index [PASI]). Methods The PSO-BIO-REAL study was a multinational, prospective, real-world, non-interventional study that included patients aged ≥ 18 years with moderate-to-severe plaque psoriasis who had initiated biologic therapy (either biologic-naïve or had switched biologics [biologic-experienced]). Psoriasis symptoms were evaluated using the PSI, and HRQoL was assessed using the DLQI. Assessments were conducted at baseline and at 6 and 12 months after initiating biologic treatment. Associations between PSI and DLQI with PASI were evaluated using Spearman correlation coefficients. Post-hoc analyses evaluated individual PSI items and the association to PASI response, DLQI and PSI by index biologic. Results At 12 months, 25.5% of patients achieved PSI 0, and 51.2% achieved DLQI 0/1, with greater proportions achieving these scores among biologic-naïve than among biologic-experienced patients. There was a moderate-to-strong correlation between PSI and DLQI scores and PASI scores, with 64.8% of patients with absolute PASI 0 and 19.4% with absolute PASI > 0 ≤ 2 achieving PSI 0 (6 and 12 months pooled). Achievement of response varied by index biologic. Conclusion This study demonstrates that in a real-world setting patients’ QoL improves with skin clearance. The results also demonstrate that the correlation between skin clearance and improvements in HRQoL (DLQI) and psoriasis symptoms (PSI) is not complete, which highlights the importance of considering both patient- and physician-reported outcomes in the assessment of psoriasis treatment outcomes.

Background Anti‐tumour necrosis factor (TNF) and anti‐interleukin (IL)‐12/23 biologics revolutionized plaque psoriasis treatment by enabling ≥75% improvement in the Psoriasis Area and Severity Index (PASI 75) in clinical trials. Modern biologics are now reported to achieve PASI 100 (complete skin clearance) in clinical trials. However, real‐world evidence of skin clearance rates with biologics is limited. PSO‐BIO‐REAL was conducted to understand the real‐world burden of plaque psoriasis. Objective The primary objective of this observational study was to estimate the proportion of patients who achieved complete skin clearance at 6 months. Secondary objectives included maintenance of response and evaluation of complete skin clearance at 12 months. Methods PSO‐BIO‐REAL was a multinational, prospective, real‐world, non‐interventional study of skin clearance and patient‐reported outcomes (PROs) with biologics. A total of 846 patients from the United States (32%), France (28%), Italy (22%), the United Kingdom (11%) and Germany (8%) were enrolled and followed for one year. Eligible patients were aged ≥18 years with moderate‐to‐severe plaque psoriasis who had initiated a biologic for plaque psoriasis. Patients could be biologic‐naïve or switching biologics (biologic‐experienced). Assessments were made at baseline and at months 6 and 12. Results At 6 and 12 months, 23% and 26% of patients achieved complete skin clearance, respectively. Prior to study entry, 60% were biologic‐naïve. The proportion of patients achieving complete skin clearance was lower among biologic‐experienced patients (20% at both months 6 and 12) compared with biologic‐naïve patients (25% at month 6, 30% at month 12). The rate of complete skin clearance decreased as the number of prior biologics and baseline comorbidities increased. Conclusion Only one in four patients achieved complete skin clearance after 6 months of treatment with biologics. The study indicates there still is an unmet need for more efficacious biologics for patients with psoriasis.

Introduction Patients with plaque psoriasis often have nail psoriasis, which is difficult to treat. Ixekizumab (IXE) and ustekinumab (UST) are biologics with established efficacy in nail psoriasis. We present post hoc data from a head-to-head trial of IXE and UST (IXORA-S) to examine the efficacy in nail psoriasis in patients with moderate-to-severe plaque psoriasis over 52 weeks. Methods In IXORA-S, randomised patients received IXE (N = 136) or UST (N = 166) per label for 52 weeks. Eighty-four (61.8%) and 105 (63.3%) of the patients treated with IXE or UST, respectively, had baseline fingernail psoriasis (Nail Psoriasis Severity Index [NAPSI] > 0); of these, 54 (64.3%) and 63 (60.0%) patients, respectively, had significant baseline fingernail psoriasis (defined as NAPSI ≥ 16 with ≥ 4 fingernails involved). The proportion of patients achieving NAPSI = 0, a NAPSI score change from baseline and correlations in Psoriasis Area of Severity Index (PASI) and NAPSI improvement over 52 weeks were examined. Results Progressive improvement occurred in both treatment groups over 52 weeks. Statistically significantly more patients achieved NAPSI = 0 with IXE versus UST by week 16–20, and the proportions continued to increase through week 52 among patients with baseline nail psoriasis (61.9 vs. 28.6%, respectively; P

We observed isolated cases of perialar intertrigo in children and teenagers that did not appear to correspond to any known clinical entity. The objective of this study was to describe the clinical features of this dermatosis and the clinical characteristics of the patients.We conducted a prospective, multicenter cohort study in France from August 2017 to November 2019. All the patients under 18 years of age with chronic perinasal intertrigo were included. A standardized questionnaire detailing the clinical characteristics of the patients and the description of the intertrigo. If possible, a Wood's lamp examination of the intertrigo was done.Forty-one patients were included (25 boys and 16 girls, average age: 12.1 years). Intertrigo was bilateral in 38 patients (93%). The majority of patients had no symptoms (54%). Pruritus was present in 39% of cases. Orange red follicular fluorescence was present in the perialar region on Wood's light examination in 78% of cases with active fluorescence. The presumptive diagnoses suggested by the investigators were acne (24.4%), seborrheic dermatitis (19.5%), rosacea (9.8%), psoriasis (9.8%) and perioral dermatitis (7.3%). No diagnosis was proposed in 22% of the cases.We describe a previously undescribed clinical sign which is characterized by a chronic bilateral erythematous intertrigo located in the perialar region. It can be isolated or associated with various facial dermatoses.

BACKGROUND Baricitinib, an oral selective Janus kinase 1 and 2 inhibitor, effectively reduced atopic dermatitis (AD) severity in a phase II study with concomitant topical corticosteroids. OBJECTIVES To evaluate the efficacy and safety of baricitinib in patients with moderate-to-severe AD who had an inadequate response to topical therapies. METHODS In two independent, multicentre, double-blind, phase III monotherapy trials, BREEZE-AD1 and BREEZE-AD2, adults with moderate-to-severe AD were randomized 2 : 1 : 1 : 1 to once-daily placebo, baricitinib 1 mg, 2 mg, or 4 mg for 16 weeks. RESULTS At week 16, more patients achieved the primary end point of Validated Investigator's Global Assessment of AD (0, 1) on baricitinib 4 mg and 2 mg compared with placebo in BREEZE-AD1 [N = 624; baricitinib 4 mg 16·8% (P < 0·001), 2 mg 11·4% (P < 0·05), 1 mg 11·8% (P < 0·05), placebo 4·8%], and BREEZE-AD2 [N = 615; baricitinib 4 mg 13·8% (P = 0·001), 2 mg 10·6% (P < 0·05), 1 mg 8·8% (P = 0·085), placebo 4·5%]. Improvement in itch was achieved as early as week 1 for 4 mg and week 2 for 2 mg. Improvements in night-time awakenings, skin pain and quality-of-life measures were observed by week 1 for both 4 mg and 2 mg (P ≤ 0·05, all comparisons). The most common adverse events in patients treated with baricitinib were nasopharyngitis and headache. No cardiovascular events, venous thromboembolism, gastrointestinal perforation, significant haematological changes, or death were observed with any baricitinib dosage. CONCLUSIONS Baricitinib improved clinical signs and symptoms in patients with moderate-to-severe AD within 16 weeks of treatment and induced rapid reduction of itch. The safety profile remained consistent with prior findings from baricitinib clinical development in AD, with no new safety concerns.

OBJECTIVE In PSO-LONG, long-term proactive management (PAM) of psoriasis with fixed-dose combination calcipotriol 50 µg/g and betamethasone dipropionate 0.5 mg/g (Cal/BD) aerosol foam was superior to conventional reactive management. This post-hoc analysis investigated long-term PAM with Cal/BD foam in PSO-LONG patients who could be more susceptible to corticosteroid-induced hypothalamic-pituitary-adrenal (HPA) axis suppression. METHODS Efficacy and safety of PAM with Cal/BD foam (twice-weekly) versus reactive management (twice-weekly vehicle foam), with once-daily rescue Cal/BD foam for four weeks following relapse, was assessed in the HPA subgroup (n = 66); patients had moderate-to-severe psoriasis (physician global assessment score ≥3; 10-30% body surface area affected). Primary endpoint was time to first relapse. RESULTS PAM with Cal/BD foam was associated with longer median time to first relapse (111 versus 31 days), reduced risk of first relapse (hazard ratio: 0.49; p = .029), greater proportion of days in remission (17%; p = .001) and reduced rate of relapse (60% reduction; p

Background: The European Organisation for Research and Treatment of Cancer (EORTC) 1325/KEYNOTE-054 trial assessed pembrolizumab versus placebo in patients with resected high-risk stage III melanoma. At 15-month median follow-up, pembrolizumab improved recurrence-free survival (hazard ratio [HR] 0·57 [98·4% CI 0·43–0·74], p1 mm), IIIB, or IIIC (without in-transit metastasis), and with an Eastern Cooperative Oncology Group performance status of 0 or 1 were eligible. Patients were randomly assigned (1:1) via a central interactive voice response system to receive intravenous pembrolizumab 200 mg or placebo every 3 weeks for up to 18 doses or until disease recurrence or unacceptable toxicity. Randomisation was stratified according to disease stage and region, using a minimisation technique, and clinical investigators, patients, and those collecting or analysing the data were masked to treatment assignment. The two coprimary endpoints were recurrence-free survival in the intention-to-treat (ITT) population and in patients with PD-L1-positive tumours. The secondary endpoint reported here was distant metastasis-free survival in the ITT and PD-L1-positive populations. This study is registered with ClinicalTrials.gov, NCT02362594, and EudraCT, 2014-004944-37. Findings: Between Aug 26, 2015, and Nov 14, 2016, 1019 patients were assigned to receive either pembrolizumab (n=514) or placebo (n=505). At an overall median follow-up of 42·3 months (IQR 40·5–45·9), 3·5-year distant metastasis-free survival was higher in the pembrolizumab group than in the placebo group in the ITT population (65·3% [95% CI 60·9–69·5] in the pembrolizumab group vs 49·4% [44·8–53·8] in the placebo group; HR 0·60 [95% CI 0·49–0·73]; p

Summary Background Tralokinumab, a fully human monoclonal antibody, specifically neutralizes interleukin‐13, a key cytokine driving peripheral inflammation in atopic dermatitis (AD). In phase II studies, tralokinumab combined with topical corticosteroids provided early and sustained improvements in AD signs and symptoms. Objectives To evaluate the efficacy and safety of tralokinumab monotherapy in adults with moderate‐to‐severe AD who had an inadequate response to topical treatments. Methods In two 52‐week, randomized, double‐blind, placebo‐controlled, phase III trials, ECZTRA 1 and ECZTRA 2, adults with moderate‐to‐severe AD were randomized (3 : 1) to subcutaneous tralokinumab 300 mg every 2 weeks (Q2W) or placebo. Primary endpoints were Investigator’s Global Assessment (IGA) score of 0 or 1 at week 16 and ≥ 75% improvement in Eczema Area and Severity Index (EASI 75) at week 16. Patients achieving an IGA score of 0 or 1 and/or EASI 75 with tralokinumab at week 16 were rerandomized to tralokinumab Q2W or every 4 weeks or placebo, for 36 weeks. The trials were registered with ClinicalTrials.gov: NCT03131648 and NCT03160885. Results At week 16, more patients who received tralokinumab vs. placebo achieved an IGA score of 0 or 1: 15·8% vs. 7·1% in ECZTRA 1 [difference 8·6%, 95% confidence interval (CI) 4·1–13·1; P = 0·002] and 22·2% vs. 10·9% in ECZTRA 2 (11·1%, 95% CI 5·8–16·4; P, What is already known about this topic? Atopic dermatitis (AD) is a chronic interleukin (IL)‐13‐mediated disease.There is a need for safe and effective long‐term treatment options for AD.Tralokinumab is a fully human monoclonal antibody that binds specifically to IL‐13 with high affinity, thereby preventing receptor interaction and subsequent downstream signalling.Tralokinumab combined with topical corticosteroids showed early and sustained efficacy and safety in a 12‐week, phase IIb trial in moderate‐to‐severe AD. What does this study add? These are the first pivotal phase III trials demonstrating that by specifically targeting IL‐13 alone, patients can achieve significant improvements in AD signs and symptoms and quality of life, and maintain these improvements over time without the requirement for topical corticosteroids.These trials provide evidence that tralokinumab offers a long‐term, well‐tolerated treatment option for patients with moderate‐to‐severe AD.

Background Patients with epidermal nevi strongly demand cosmetic improvement. Laser treatment appears appealing and is frequently used in clinical practice. Nevertheless, large series with long-term follow-up are missing, preventing definitive conclusions about its real benefit. Objective To evaluate the long-term effectiveness and safety of lasers for epidermal nevi. Methods Bicentric, retrospective, cohort study, including all patients treated with a laser for an epidermal nevus with more than a one-year follow-up. Results Seventy patients were treated for different types of epidermal nevi, mostly with ablative lasers: 23 verrucous epidermal nevi, 16 nevi sebaceous, 26 Becker nevi, two inflammatory linear verrucous epidermal nevi, one smooth-muscle hamartoma, one rounded and velvety epidermal nevus, and one nevus lipomatosus superficialis. The follow-up period ranged between 12 and 127 months (median 37 months). Better results, fewer recurrences, and higher patient satisfaction were noted in treatments for verrucous epidermal nevi than for nevi sebaceous. Q-switched (QS) lasers failed to show any degree of improvement in almost all patients with Becker nevus. Limitations The retrospective nature of the study. Conclusions Ablative lasers can treat verrucous epidermal nevi with good long-term esthetic results, but they have limited long-term efficacy for nevus sebaceous. Q-switched lasers failed to improve Becker nevi.

Topical psoriasis treatment relies on a reactive rather than a long-term proactive approach to disease relapse.Assess long-term efficacy and safety of proactive psoriasis management with twice-weekly calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) foam.Phase III trial (NCT02899962) included a 4-week open-label lead-in phase (Cal/BD foam once daily) and a 52-week, randomized, double-blind, maintenance phase. A total of 545 patients achieved treatment success (physician's global assessment "clear"/"almost clear," ≥2-grade improvement from baseline) and were randomized to proactive management (Cal/BD foam; n = 272) or reactive management (vehicle foam; n = 273) twice-weekly, with rescue treatment of Cal/BD foam once daily for 4 weeks upon relapse. Primary endpoint was time to first relapse (physician's global assessment "mild" or higher).A total of 251 randomized patients (46.1%) completed the trial. Median time to first relapse was 56 days (proactive) and 30 days (reactive). Patients in the proactive group had an additional 41 days in remission compared with the reactive group over 1 year (P .001). Number of relapses per year of exposure was 3.1 (proactive) and 4.8 (reactive). Cal/BD foam was well tolerated.Maintenance phase dropout rate (53.9%) was within the expected range but provides challenges in statistical analysis.Long-term proactive management with Cal/BD foam demonstrated superior efficacy vs reactive management.

The mutation status of the BRAF and NRAS genes in tumor tissue is used to select patients with metastatic melanoma for targeted therapy. Cell-free circulating DNA (cfDNA) represents an accessible, non-invasive surrogate sample that could provide a snapshot of the BRAF and NRAS genotype in these patients. We investigated the feasibility of the Idylla™ assay for detection of BRAF and NRAS mutations in cfDNA of 19 patients with metastatic melanoma at baseline and during the course of treatment. The cfDNA genotype obtained with Idylla was compared to the results obtained with matched-tumor tissue and to clinical outcome. At baseline, 47% of patients harbored a BRAFV600 mutation in their cfDNA. Two months after targeted treatment the BRAFV600 mutant cfDNA was undetectable in all patients and 3 were disease-free. Moreover, 15% of patients harbored a NRAS mutation that was detected with plasma before treatment. The sensitivity and specificity were 80% and 89% for the BRAF status, and 79% and 100% for the NRAS status in pretreatment cfDNA compared to results obtained with a tissue test. Due to the small size of the population, no significant correlation was observed between the presence of BRAF or NRAS mutations in cfDNA and the metastatic tumor load or overall survival. In conclusion, this study demonstrated that evaluation with the Idylla system of the BRAF and NRAS mutation status in cfDNA may be a surrogate for determination of the BRAF and NRAS status in tumor tissue.

Psoriasis affects 2–4% of the population, with the most common clinical type being plaque psoriasis. The linear form of psoriasis is very rare. The literature on linear psoriasis (LP) consists of only case reports, and data are few. This study aimed to better understand LP in a large-scale study. We retrospectively retrieved the medical records from 14 French medical centers of patients newly diagnosed clinically with LP, with or without the support of histology, between 1 February and 31 July 2015. For each case, we assessed the clinical features, treatments and treatment efficacy. In total, 30 cases of LP (mean age 26.8 years, 13 males) were reported. Mean age at onset of LP was 20.0 years, with 18 developing LP in childhood. Ten patients had a family history of psoriasis, and two had psoriatic arthritis. A total of 19 cases were linear at onset, with concomitant classical psoriasis; these were termed “superimposed” LP. The remaining 11 cases were not associated with classical psoriasis and were termed “isolated” LP. In four of the superimposed cases, LP developed when the patient was receiving systemic treatment: methotrexate (n = 2), etanercept (n = 1) or infliximab (n = 1). Topical steroids were effective in 76% of cases in which they were used, and systemic treatment was effective in

Introduction Certains patients psoriasiques ne repondent pas a une premiere biotherapie (1). Le changement therapeutique peut etre une option therapeutique pour ces patients. Peu de donnees sont disponibles sur le switch de biotherapies dans le psoriasis de l’enfant. Evaluer la pratique clinique, l’efficience et la tolerance en vie courante du switch de biotherapie dans une cohorte retrospective sur les biotherapies dans le psoriasis de l’enfant (BiPe). Materiel et methodes Les donnees des 134 patients inclus dans la cohorte BiPe ont ete analysees. Une evaluation de la sous-population de patients ayant switche d’une premiere a une deuxieme biotherapie a ensuite ete effectuee. Les taux de survie des biotherapies ont egalement ete compares entre les biotherapies administres comme agents de premiere ou de deuxieme ligne. Resultats Au total, 29 enfants (filles : 55 % ; âge moyenne : 16,6 ± 3,0 ans) ont recu deux biotherapies. L’etanercept (ETN) etait la biotherapie de 1re ligne utilisee chez 23 enfants : 16 (69,6 %) sont passes a l’adalimumab (ADA) et sept (30,4 %) a l’ustekinumab (UST). Six enfants ont recu l’ADA en 1re ligne et sont passes a l’UST. Les principales raisons etaient la perte d’efficacite (62,1 %), l’inefficacite primaire (20,7 %) et le choix du parent (6,9 %). Un switch (3,4 %) a ete effectue en raison d’evenements indesirables ou d’intolerance. Pour l’UST et l’ADA, le taux de survie de la biotherapie a 18 mois ne differait pas selon que l’agent etait administre en tant que biotherapie de 1re ou de 2e intention (UST : p = 0,24 ; ADA : p = 0,68). Aucune difference significative dans les taux de survie des biotherapies n’a ete observee entre les trois differents switchs (ADA a UST, ETN a ADA, et ETN a UST). Aucun evenement indesirable grave n’a ete note apres les switchs. Discussion Notre etude a permis de fournir des informations importantes sur le switch de biotherapies en vie courante chez les patients atteints de psoriasis pediatrique. Il n’y a pas de perte d’efficacite notable du traitement donne en 2e intention, et la tolerance parait excellente. Cependant, plus d’informations sont necessaires afin d’ameliorer les pratiques en vie courante et pour confirmer ces resultats.

Introduction Le dupilumab est autorise dans le traitement de la dermatite atopique (DA) moderee a severe. Decrits au cours des etudes cliniques et confirmes en vie-reelle, des effets indesirables oculaires (EIO) ont ete rapportes chez les patients traites pour une DA. Bien que frequents, la caracterisation de ces EIO restent limitee en raison souvent du faible nombre de patients decrits/ou de l’absence d’examen ophtalmologique systematique. Notre etude a pour objectif de combiner une approche dermatologique et ophtalmologique afin de preciser l’incidence, les caracteristiques cliniques et les facteurs de risque de l’atteinte oculaire. Materiel et methodes Etude prospective, multicentrique, en vie reelle chez des patients adultes atteints de DA traites par dupilumab. Les caracteristiques demographiques et cliniques des patients atteints de DA etaient decrites. Une evaluation ophtalmologique initiale et a 4 mois (M4) etait systematique chez tous les patients inclus. Resultats Un total de 181 patients ont ete inclus. L’âge median etait de 36 ans, le SCORAD moyen a j0 etait de 46 et 43 % des patients avaient des antecedents de troubles ophtalmologiques atopiques. L’incidence des conjonctivites a M4 etait de 19 % (35 patients). Parmi eux, 20 patients ont developpe une conjonctivite de novo et 15 patients ont aggrave une conjonctivite deja presente. En analyse bivariee, a l’inclusion, un âge plus eleve (p = 0,028) la severite de la DA estimee par le SCORAD (p = 0,08) et une atteinte erythrodermique (p = 0,009) etaient associes au developpement d’une conjonctivite a M4. On notait une tendance a l’association entre une atteinte cervico-faciale objectivee a M4 et la survenue d’une conjonctivite (p = 0,07). Les antecedents personnels ou familiaux de comorbidites atopiques, les antecedents de conjonctivites a j0 ou un taux eleve d’IgE n’etaient pas associes a une conjonctivite. Discussion Nos resultats sur l’incidence sont concordants avec les donnees actuelles de la litterature. Concernant les facteurs de risque, les phenotypes cliniques des patients semblent particulierement interessants pour cibler les patients a risques d’EIO. Alors que la severite initiale avait deja ete mise en evidence dans deux etudes anterieures, l’erythrodermie initiale et l’atteinte « tete et cou » en cours de traitement sont evoques comme facteurs de risques pour la premiere fois. D’autres facteurs cliniques ne sont pas confirmes par notre etude. En conclusion, il s’agit de la plus large cohorte de patients traites par dupilumab pour une DA evalues systematiquement et prospectivement jusqu’a M4. La connaissance de l’incidence reelle des EIO et de leurs facteurs de risque permettra d’ameliorer la prise en charge des patients eligibles a ce traitement.

Introduction Les modifications pilaires a type d’hypertrichose sont frequentes dans les naevus congenitaux. Les naevus congenitaux peuvent egalement etre associes a une alopecie. Les caracteristiques de ces alopecies ne sont pas decrites. L’objectif de cette serie de cas est de decrire les caracteristiques cliniques et dermoscopiques des alopecies associees aux naevus congenitaux du cuir chevelu. Materiel et methodes Cinq patients porteurs de naevus congenital du cuir chevelu associe a une alopecie congenitale ont ete observes. L’âge median des patients etait de 2 ans (s’etendant de 26 jours a 4 ans), et leur sexe etait exclusivement masculin. Les naevus etaient localises a l’aire parietale droite (4/5) ou au vertex (1/5) et leur taille mediane etait de 8 cm (s’etendant de 3,5 a 20 cm). L’analyse dermoscopique trouvait un patron homogene-globulaire (4/5) ou homogene (1/5), une hyperpigmentation (2/5) ou hypopigmentation (1/5) perifolliculaire, une hypopigmentation localisee (3/5) et des pseudokystes miliaires (1/5). Tous les patients partageaient les memes caracteristiques trichoscopiques avec des cheveux de differentes longueurs, une anisotrichie, des points noirs, et des cheveux dystrophiques en « tache d’encre », semblables a un stylo qui fuit. L’analyse histologique d’une biopsie cutanee retrouvait un aspect typique de naevus congenital avec des melanocytes disposes en theques et en file indienne jusque dans l’hypoderme, l’extension des melanocytes autour et au sein de l’annexe pilosebacee avec invasion des gaines pilaires et du muscle erecteur du poil. Etaient egalement notes des amas pigmentaires autour de cheveux au sein des ostium folliculaires. Discussion L’examen dermoscopique des naevus congenitaux du cuir chevelu dans notre serie de cas est semblable a celui decrit dans la litterature. Le signe trichoscopique particulier de « tache d’encre » sur les zones alopeciques, associe a une anisotrichie et a des cheveux dystrophiques suggere que l’alopecie est secondaire a une destruction du cheveu par le naevus, comme en temoigne l’invasion intrafolliculaire des melanocytes et les amas pigmentaires au sein des ostium folliculaires en analyse anatomopathologique. Le signe de la « tache d’encre » semble etre la correspondance dermoscopique de ces amas pigmentaires et serait donc un marqueur de l’invasion folliculaire.

Introduction Le mycosis fongoide (MF) de l’enfant est rare. Son profil evolutif a l’âge adulte est mal connu. Notre objectif etait de decrire les profils epidemiologique/clinique/histologique/therapeutique et evolutif du MF de l’enfant. Materiel et methodes Dans cette etude multicentrique retrospective, nous avons inclus les patients avec MF confirme avant l’âge de 18 ans ; traitements et evolution (si suivi superieur a 1 an) ont ete analyses. Resultats 47 patients ont ete inclus, dont 40 analysables pour le suivi (âge median aux premiers symptomes 7,8 ans, au diagnostic 11 ans, sexe ratio M/F = 3/1). Au diagnostic, 85 % etaient au stade I. Les lesions etaient en patchs dans 64 %, hypopigmentees dans 41 %. La forme histologique etait pilotrope dans 20 cas (43 %), dont 12 avec mucinose folliculaire. Le phenotype etait CD8+ dans 19 % des cas, sans association significative avec la presence de lesions hypopigmentees (p = 0,136). Une abstention therapeutique initiale etait proposee a 6/40 (15 %) des patients, 28/40 (70 %) etaient traites par traitements locaux (topique/phototherapie) et 6/40 (15 %) recevaient un traitement systemique. Une reponse clinique etait obtenue chez 28/40 (70 %) patients (complete RC 10 et partielle RP 18). Une RC etait plus souvent observee en 1ere ligne dans les formes CD8 + (p = 0,049). Une rechute etait constatee chez 14/40 (35 %) patients (delai median pour la 1ere rechute : 22 mois). Apres une duree mediane de suivi de 57 mois (12–216), une reponse clinique etait observee dans 31/40 (78 %) des cas (RC 14, RP 17), une stabilite dans 6 (15 %), une progression dans 3 (7,5 %) (1 stade IIB apres 10 ans et 2 stades IV apres 1 et 5,6 ans) et une transformation chez 4 patients (10 %) dont les 3 ayant progresse et 3 apres plus de 12 ans (phenotype CD4+ pour 3/4). Chez les 16 patients devenus adultes, 14 (88 %) ont evolue vers un MF de l’adulte : âge median aux premiers symptomes et au diagnostic plus tardif (10,8 et 12,5 ans), phenotype majoritairement CD4+ (12/14, 86 %). A la derniere visite, 9/14 (64 %) etaient toujours en reponse clinique (RC 2, RP 7). Discussion Une predominance masculine est observee dans cette serie de MF pediatrique. La forme hypopigmentee est plus frequente que chez l’adulte, mais non associee a la reponse clinique. Le phenotype CD8+, trouve dans 19 % des cas (taux relativement bas par rapport aux autres series pediatriques) n’est pas particulierement associe aux formes hypopigmentees mais correle a une meilleure RC en 1ere ligne. Les traitements locaux semblent efficaces dans la plupart des cas. L’evolution est majoritairement indolente avec un bon pronostic d’ensemble. Cependant une transformation souvent tardive est constatee chez presque 10 % des patients, taux superieur a celui des autres series pediatriques mais similaire a celui observe chez l’adulte (10 a 22 %). La persistance de la maladie a l’âge adulte est frequente et incite a une surveillance au long cours.

Introduction Le tildrakizumab (TIL) est un anticorps monoclonal ciblant specifiquement l’IL-23p19 approuve pour le psoriasis en plaques modere a severe. L’objectif etait d’evaluer le taux d’infections severes sur 5 ans des essais de phase 3 reSURFACE1/2 ( NCT01722331 / NCT01729754 ). Materiel et methodes Analyse groupee de patients (pts) adultes atteints de psoriasis en plaques modere a severe provenant de 2 essais controles, randomises, en double insu, a groupes paralleles : reSURFACE1 (64 semaines [S]) et reSURFACE2 (52S). Apres avoir termine ces etudes, les pts ayant au moins une reponse PASI50 sont entres dans une periode d’extension facultative de 4 ans allant jusqu’a la S256 (reSURFACE1)/S244 (reSURFACE2). Les donnees de securite sur 256S regroupees entre les essais et les groupes de traitement ont ete incluses. Les groupes etaient definis comme : TIL 200 mg (pts ayant recu TIL 200 mg dans au moins une partie de l’etude), TIL 100 mg (pts ayant recu TIL 100 mg dans au moins une partie de l’etude), placebo (pbo) (pts ayant recu pbo pendant la partie 1 ou etant re-randomises au pbo a la S28) et etanercept (ETN) (pts ayant recu ETN 50 mg jusqu’a la S28). Les infections graves ont ete definies comme toute infection repondant a la definition reglementaire d’evenement indesirable grave (EIG) et/ou necessitant des antibiotiques par voie intraveineuse, qu’elle ait ete declaree comme EIG ou non. Les taux d’incidence ajustes sur l’exposition (TIAE) sont rapportes (i.e., evenements pour 100 pts-annees [PA] d’exposition) pour tous les sujets en tant que population traitee. Resultats Au total, 928 pts sous TIL 200 mg, 872 sous TIL 100 mg, 543 sous pbo et 313 sous ETN ont ete inclus. Le TIAE des infections severes etait de 1,25/100 PA d’exposition sous TIL 200 mg et 1,18 (TIL 100 mg) au cours des 5 annees de traitement. Les groupes pbo et ETN ont eu respectivement 0,97 et 1,96 evenements pour 100 PA. Les types d’infections severes les plus frequemment rapportes etaient des dermo-hypodermites (4 pts sous TIL 200 mg [0,14 evenement pour 100 PA], 4 pts sous TIL 100 mg [0,14 evenement pour 100 PA], 2 pts sous pbo [0,97 evenements pour 100 PA] et 1 pt sous ETN [0,65 evenement pour 100 PA]) ; des diverticulites (7 pts sous TIL 200 mg [0,24 evenement pour 100 PA] et 6 pts sous TIL 100 mg [0,21 evenements pour 100 PA]) ; des zonas (1 pt sous TIL 200 mg [0,03 evenements pour 100 PA] et 1 pt sous ETN [0,65 evenement pour 100 PA]) et une infection urinaire (1 pt sous ETN [0,65 evenements pour 100 PA]). Discussion Le tildrakizumab a montre un profil de securite favorable avec un faible taux d’infections severes sur 5 ans de traitement, comparable a ceux rapportes precedemment. Les TIAE etaient inferieurs a ceux de l’etanercept et comparables au placebo. Aucun nouveau signal de securite n’a ete rapporte au cours du traitement a long terme.

Prurigo nodularis is a chronic pruritic skin disease with multiple nodular skin lesions. Nemolizumab is a monoclonal antibody targeting the interleukin-31 receptor, which is involved in the pathogenesis of prurigo nodularis.We conducted a 12-week, randomized, double-blind, phase 2 trial of nemolizumab (at a dose of 0.5 mg per kilogram of body weight) administered subcutaneously at baseline, week 4, and week 8, as compared with placebo, in patients with moderate-to-severe prurigo nodularis and severe pruritus. Moderate-to-severe prurigo nodularis was defined as 20 or more nodules, and severe pruritus was defined as a mean score of at least 7 for the worst daily intensity of pruritus on the numerical rating scale (scores range from 0 [no itch] to 10 [worst itch imaginable]). The primary outcome was the percent change from baseline in the mean peak score for pruritus on the numerical rating scale at week 4. Secondary outcomes included additional measures of itching and disease severity. Safety assessments were performed through week 18.A total of 70 patients were randomly assigned in a 1:1 ratio to receive nemolizumab (34 patients) or placebo (36). The initial pruritus score on the numerical rating scale was 8.4 in each group. At week 4, the peak pruritus score on the numerical rating scale was reduced from baseline by 4.5 points (change, -53.0%) in the nemolizumab group, as compared with a reduction of 1.7 points (change, -20.2%) in the placebo group (difference, -32.8 percentage points; 95% confidence interval, -46.8 to -18.8; P0.001). Results for secondary outcomes were in the same direction as for the primary outcome. Nemolizumab was associated with gastrointestinal symptoms (abdominal pain and diarrhea) and musculoskeletal symptoms.Nemolizumab resulted in a greater reduction in pruritus and severity of skin lesions than placebo in patients with prurigo nodularis but was associated with adverse events. Larger and longer trials are needed to determine the durability and safety of nemolizumab for the treatment of prurigo nodularis. (Funded by Galderma; ClinicalTrials.gov number, NCT03181503.).

International audience; BackgroundDupilumab is the first biologic available to treat atopic dermatitis (AD). Its effectiveness and safety were demonstrated in clinical trials.ObjectiveWe sought to assess the effectiveness and safety of dupilumab in adults with AD in a real-life French multicenter retrospective cohort.MethodsWe included patients treated during March 2017-April 2018. Efficacy outcomes, including Scoring Atopic Dermatitis (SCORAD) and Eczema Area and Severity Index (EASI) scores, were collected at baseline and 3 months when available. Adverse events (AEs) were recorded at follow-up.ResultsWe included 241 patients. The median ± interquartile range (IQR) follow-up time was 3.8 ± 3.7 months. A ≥75% improvement in SCORAD was achieved in 27 of 163 (16.6%) patients, and a ≥75% improvement in EASI was achieved in 40 of 82 (48.8%) patients. The median SCORAD and EASI scores at 3 months were significantly lower than those at baseline (SCORAD ± IQR, 25 ± 21 vs 56 ± 27.4, P < 10−9 and EASI ± IQR, 4.1 ± 6.8 vs 17.9 ± 15.4, P < 10−9, respectively). Conjunctivitis was reported in 84 of 241 (38.2%) patients. The proportion with eosinophilia (>500 cells/mm3) during follow-up (57%) was higher than that at baseline (33.7%) (n = 172, P < 10−6). Dupilumab was stopped in 42 cases; 27 patients stopped because of AEs.LimitationsNo control group, missing data.ConclusionThis real-life study demonstrated a similar dupilumab effectiveness as that seen in clinical trials, but it also revealed a higher frequency of conjunctivitis and eosinophilia.

BACKGROUND Secukinumab is a fully human monoclonal antibody that selectively binds to and neutralizes interleukin-17A. OBJECTIVES To assess the efficacy and safety of different maintenance dosing regimens of secukinumab 300 mg based on Psoriasis Area and Severity Index (PASI) response at week 24 in patients with moderate-to-severe plaque psoriasis. METHODS OPTIMISE was a randomized, open-label, rater-blinded phase IIIb study. Patients (n = 1647) received secukinumab 300 mg at baseline; weeks 1, 2, 3 and 4; and every 4 weeks (q4w) to week 24. At week 24, PASI 90 responders (≥ 90% improvement in PASI; n = 1306) were randomized to secukinumab 300 mg q4w (n = 644) or q6w (n = 662) to week 52, and PASI ≥ 75 to < 90 responders (n = 206) were randomized to secukinumab 300 mg q4w (n = 114) or q2w (n = 92) to week 52. RESULTS PASI 90 response was maintained at week 52 by 85·7% of patients with q4w dosing vs. 74·9% with q6w dosing (odds ratio 1·91, 95% confidence interval 1·44-2·55). The primary end point, noninferiority of q6w vs. q4w dosing, was not met. In PASI ≥ 75 to < 90 responders, the proportion of patients with PASI 90 response at week 52 was numerically higher in the q2w vs. the q4w group (57% vs. 46·5%, respectively, P = 0·10). Heavier patients (≥ 90 kg) demonstrated numerically higher PASI 90 response with the q2w (57·1%) vs. the q4w regimen (40%, P = 0·11). CONCLUSIONS Standard q4w dosing of secukinumab 300 mg is the optimal dosing regimen to achieve and maintain clear or almost clear skin. Patients with body weight ≥ 90 kg not achieving PASI 90 at week 24 may benefit from the q2w dosing regimen. What's already known about this topic? Individual responses to biologics in patients with psoriasis vary considerably and there may be a need to individualize treatment. Dose optimization strategies of currently available biologic drugs have been investigated mainly in rheumatic disorders. Secukinumab has shown long-term PASI 90/100 responses (percentage improvement in Psoriasis Area and Severity Index) to year 5 in patients with moderate-to-severe plaque psoriasis when used at the dose of 300 mg every 4 weeks. What does this study add? Standard every 4 week (q4w) dosing of secukinumab 300 mg is the optimal regimen to achieve and maintain clear or almost clear skin at week 52; the majority of the patients (85·7%) maintain PASI 90 at week 52. Superiority of intensified (q2w) dosing over the q4w regimen could not be claimed. However, patients with a higher body weight (≥ 90 kg) not achieving PASI 90 response at week 24 may benefit from q2w dosing.

International audience; The prognosis of advanced melanoma has been greatly improved by new therapeutic agents and clinicians rely on dynamic signals to drive their therapeutic choices. Although the kinetics of metastatic disease seem to be correlated with survival, progression of the localized disease is not predictable.Objective: To assess whether progression of metastatic disease is associated with the time to the first distant recurrence of melanoma.Design, Setting, and Participants: This study was conducted from March 1, 2013, to September 1, 2017, among 638 adults with unresectable stage III or IV melanoma within the French multicentric prospective cohort MelBase. Patients treated with first-line immunotherapies, targeted therapies, or chemotherapy were included. Patients with unknown primary or de novo metastatic melanoma were not included. Data were analyzed from March 1, 2013, to December 1, 2017.Main Outcomes and Measures: The date of primary excision and time to first distant recurrence, progression-free survival, and overall survival were collected. Cox proportional hazards regression models were planned to assess the association between time to first distant recurrence and progression-free survival or overall survival, which was evaluated in terms of hazard ratio (HR). Time to recurrence was analyzed both as a continuous and categorical variable (24 months).Results: A total of 638 patients (272 women and 366 men; median age, 64 years [interquartile range, 52-73 years]) were included in the study. The median time from primary excision to first distant recurrence was 25 months (interquartile range, 12-55 months). There was no evidence of association of the time to recurrence with progression-free survival, both when analyzed as a continuous variable (HR, 0.99; 95% CI, 0.99-1.01) or after categorization (12-24 months: HR, 0.75; 95% CI, 0.56-1.02; >24 months: HR, 0.62; 95% CI; 0.47-1.01). There was no evidence of association of the time to recurrence with overall survival, both when analyzed as a continuous variable (HR, 0.99; 95% CI, 0.98-1.02) or after categorization (12-24 months: HR, 0.76; 95% CI, 0.54-1.07; >24 months: HR, 0.61; 95% CI, 0.54-1.03). Those results remained nonsignificant after stratification by treatment.Conclusions and Relevance: In the MelBase cohort, time to recurrence of metastatic melanoma appears not to be associated with progression-free survival or overall survival.

International audience; Background: Melanoma brain metastases (MBMs) are historically associated with poor prognosis. Radiation therapy is conventionally associated with a high local control rate. Development of targeted therapy and immunotherapy has improved overall survival (OS) and intracranial response rate, but about 50% of patients failed to respond to these novel therapies. The objective of this study was to assess the impact of combined radiotherapy (cRT) on overall survival in a large multicenter real-life prospective cohort of patients with MBM treated with immunotherapy or targeted therapy.Patients and methods: Clinical data from 262 patients with MBM were collected via MelBase, a French multicentric biobank prospectively enrolling unresectable stage III or IV melanoma. Two groups were defined: patients receiving cRT (cRT group) or not receiving cRT (no-cRT group). Primary end-point was OS. Propensity score weighting was used to correct for indication bias.Results: Among the 262 patients, 93 (35%) received cRT (cRT group). The patients were treated with immunotherapy in 69% and 60% and with targeted therapy in 31% and 40% of the cRT and no-cRT groups, respectively. With a median follow-up of 6.9 months, median OS was 16.8 months and 6.9 months in the cRT and no-cRT groups, respectively. After propensity score weighting, cRT was associated with longer OS (hazard ratio = 0.6, 95% confidence interval: 0.4-0.8; p=0.007). Median OS after ponderation was 15.3 months and 6.2 months in the cRT and no-cRT groups, respectively.Conclusion: This study shows that cRT may be associated with a significant decrease of 40% in the risk of death in patients with MBM treated with systemic therapy.
