Moderate-to-severe atopic dermatitis in adolescents treated with dupilumab: A multicentre Italian real-world experience.

BACKGROUND: Moderate-to-severe atopic dermatitis (AD) in the adolescence is a high burden disease, and its treatment can be very challenging due to paucity of approved systemic drugs for this age and their side-effects. Dupilumab was recently approved for treatment of adolescent AD. OBJECTIVES: A multicentre, prospective, real-world study on the effectiveness and safety of dupilumab in adolescents (aged from ≥12 to <18 years) with moderate-to-severe AD was conducted. The main AD clinical phenotypes were also examined. METHODS: Data of adolescents with moderate-to-severe AD treated with dupilumab at label dosage for 16 weeks were collected. Treatment outcome was assessed by EASI, NRS itch, NRS sleep loss and CDLQI scores at baseline and after 16 weeks of treatment. The clinical scores were also evaluated according to clinical phenotypes. RESULTS: One hundred and thirty-nine adolescents were enrolled in the study. Flexural eczema and head and neck eczema were the most frequent clinical phenotypes, followed by hand eczema and portrait-like dermatitis. Coexistence of more than 1 phenotype was documented in 126/139 (88.5%) adolescents. Three patients (2.1%) contracted asymptomatic SARS-CoV-2 infection and 1 of the discontinued dupilumab treatment before the target treatment period. A significant improvement in EASI, NRS itch, NRS sleep loss and CDLQI was observed after 16 weeks of treatment with dupilumab. This outcome was better than that observed in clinical trials. Dupilumab resulted effective in all AD phenotypes, especially in diffuse eczema. Twenty-eight (20.1%) patients reported adverse events, conjunctivitis and flushing being the most frequent. None of patients discontinued dupilumab due to adverse event. CONCLUSIONS: Dupilumab in adolescent AD showed excellent effectiveness at week 16 with consistent improvement of all clinical scores. Moreover, dupilumab showed a good safety profile also in this COVID-19 pandemic era.

Use of Dupilumab in 543 Adult Patients With Moderate-to-Severe Atopic Dermatitis: A Multicenter, Retrospective Study.

BACKGROUND: Dupilumab has proven to be an effective treatment for patients with moderate-to-severe atopic dermatitis (AD) in clinical trials. However, real-world experience with dupilumab in a broader population is limited. METHODS: The study population comprised adult patients with moderate-to-severe AD, defined as an Eczema Area Severity Index (EASI) score of 24 or higher, treated with dupilumab at 10 Italian teaching hospitals. We analyzed physician-reported outcome measures (EASI), patient-reported outcome measures (pruritus and sleep score, Dermatology Life Quality Index [DLQI]), and serological markers (IgE and eosinophil count) after 16 weeks. RESULTS: We enrolled 543 patients with moderate-to-severe AD. Two patients (0.4%) discontinued treatment. The median (IQR) change from baseline to 16 weeks of treatment in the EASI score was -87.5 (22.0) (P<.001). The EASI-50, EASI-75, and EASI-90 response rates were 98.1%, 81.5%, and 50.8% after 16 weeks. At 16 weeks, 93.0% of the patients had achieved a 4-point or higher improvement in DLQI from baseline. During treatment with dupilumab, 12.2% of the patients developed conjunctivitis, and total IgE decreased significantly (P<.001). Interestingly, in the multivariate logistic regression model, the risk of developing dupilumab-related conjunctivitis was associated with early onset of AD (OR, 2.25; 95%CI, 1.07-4.70; P=.03) and presence of eosinophilia (OR, 1.91; 95%CI, 1.05-3.39; P=.03). CONCLUSION: This is the broadest real-life study in AD patients treated with dupilumab to date. We observed more significant improvements induced by dupilumab in adult patients with moderate-to-severe AD than those reported in clinical trials.

Antecedentes: Se ha demostrado en ensayos clínicos que dupilumab es un tratamiento eficaz para pacientes con dermatitis atópica (DA)de moderada a grave. Sin embargo, la experiencia en vida real con dupilumab y con gran número de pacientes es más limitada.Métodos: Se incluyeron en el estudio pacientes adultos con DA de moderada a grave, definida como un índice de gravedad del área deeccema (EASI) de 24 o más, tratados con dupilumab en diez centros universitarios italianos. Se analizaron parámetros medidos por elmédico (EASI), por el paciente (puntuación de prurito y sueño, índice de calidad de vida dermatológica DLQI) y marcadores serológicos(inmunoglobulina IgE y recuento de eosinófilos en sangre) a las 16 semanas de tratamiento.Resultados: Se incluyeron 543 pacientes con DA de moderada a grave. Dos pacientes (0,4%) interrumpieron el tratamiento. La mediana± cambio porcentual intercuartílico desde el inicio hasta las 16 semanas de tratamiento en la puntuación EASI fue de -87,5 ± 22,0(p <0,001). Las tasas de respuesta de EASI-50, EASI-75 y EASI-90 fueron del 98,1%, 81,5% y 50,8% después de 16 semanas. En lasemana 16, el 93% de los pacientes habían logrado una mejora de 4 puntos o más en el DLQI desde el inicio. Durante el tratamiento condupilumab, el 12,2% de los pacientes desarrollaron conjuntivitis y la IgE total disminuyó significativamente (p <0,001). Curiosamente, enel modelo de regresión logística multivariante, el riesgo de desarrollar conjuntivitis relacionada con dupilumab se asoció con la aparicióntemprana de DA (OR, 2,25; IC del 95%, 1,07–4,70; p = 0,03) y presencia de eosinofilia (OR, 1,91; IC del 95%, 1,05–3,39; p = 0,03).Conclusión: Hasta la fecha, este es el estudio más amplio en vida real en pacientes con DA tratados con dupilumab. Se observaron mejorassignificativas y más importantes que las notificadas en los ensayos clínicos realizados con dupilumab (AU)

Dupilumab therapy of atopic dermatitis of the elderly: a multicentre, real-life study.

BACKGROUND: Treatment of moderate-to-severe atopic dermatitis (AD) in the elderly may be challenging, due to side-effects of traditional anti-inflammatory drugs and to comorbidities often found in this age group. Furthermore, efficacy and safety of innovative drugs such as dupilumab are not yet well known. OBJECTIVES: A multicentre retrospective, observational, real-life study on the efficacy and safety of dupilumab was conducted in a group of patients aged ≥65 years and affected by severe AD. Their main clinical features were also examined. METHODS: Data of elderly patients with severe (EASI ≥24) AD treated with dupilumab at label dosage for 16 weeks were retrospectively collected. Treatment outcome was assessed by comparing objective (EASI) and subjective (P-NRS, S-NRS and DLQI) scores at baseline and after 16 weeks of treatment. RESULTS: Two hundred and seventy-six patients were enrolled in the study. They represented 11.37% of all patients with severe AD. Flexural eczema was the most frequent clinical phenotype, followed by prurigo nodularis. The coexistence of more than one phenotype was found in 63/276 (22.82%) subjects. Data on the 16-week treatment with dupilumab were available for 253 (91.67%) patients. Efficacy of dupilumab was demonstrated by a significant reduction of all the scores. No statistically significant difference regarding efficacy was found in elderly patients when compared to the group of our AD patients aged 18-64 years, treated with dupilumab over the same period. Furthermore, only 18 (6.52%) patients discontinued the drug due to inefficacy. Sixty-one (22.51%) patients reported adverse events, conjunctivitis and flushing being the most frequent. One (0.36%) patient only discontinued dupilumab due to an adverse event. CONCLUSIONS: Therapy with dupilumab led to a significant improvement of AD over a 16-week treatment period, with a good safety profile. Therefore, dupilumab could be considered as an efficacious and safe treatment for AD also in the elderly.

Real-life experience on effectiveness and safety of dupilumab in adult patients with moderate-to-severe atopic dermatitis.

BACKGROUND: Dupilumab, a fully human monoclonal antibody targeting the alpha subunit of IL-4 was recently approved for the treatment of moderate-to-severe atopic dermatitis (AD) in adult patients. OBJECTIVE: To assess dupilumab effectiveness and safety in adults with moderate-to-severe AD in a real-life Italian multicentre retrospective cohort. METHODS: Adult moderate-to-severe AD patients, referring to 39 Italian centers, received dupilumab in the context of a national patient access program. Disease assessment was performed at baseline, after 4 and 16 weeks of treatment using Eczema-Area-and-Severity-Index (EASI) score, itch and sleep numerical-rating-score (itch-NRS, sleep-NRS) and Dermatology-Life-Quality-Index (DLQI). RESULTS: A total of 109 (71 M/38F) patients was studied. There was a significant reduction in EASI score, itch-NRS, sleep-NRS and DLQI from baseline to week 4 and a further significant decline to week 16. EASI 50, EASI75 and EASI90 were achieved by 59.6%, 28.4% and 9.3% of patients at 4 weeks and by 87.2%, 60.6% and 32.4% of them at 16 weeks, respectively. Adverse events were experienced by 19.2% (21/109) of the patients and they were all mild in intensity, being conjunctivitis the most common side effect. CONCLUSIONS: Dupilumab significantly improved disease severity, pruritus, sleep loss and quality of life with an acceptable safety profile.

Efficacy and safety of dupilumab in atopic dermatitis in elderly patients: a retrospective study.

Atopic dermatitis (AD) is a common inflammatory skin disease with high prevalence in both children (15-30%) and adults (2-10%), but limited data are available for older people. Elderly patients form a challenging group, as multiple comorbidities, associated polypharmacy and failures with previous treatments are common. We performed a retrospective observational study on elderly (≥ 65 years) patients treated with dupilumab, monoclonal antibody to the shared alpha subunit of the interleukin-4 and -13 receptor approved for the treatment of moderate-to-severe AD in adults.
