Dupilumab Effect on Pruritus Neuro-mechanisms in Patients With Atopic Dermatitis
Bu çalışma, orta-şiddetli atopik dermatit (atopic dermatitis) olan hastalarda Dupilumab ilacının kaşıntıyla ilgili sinir mekanizmaları üzerindeki etkisini incelemektedir. Çalışmaya, en az bir yıldır kronik atopik dermatiti olan ve belirli kaşıntı düzeyindeki 18 yaş ve üzeri hastalar ile sağlıklı gönüllüler katılmıştır. Faz 4 aşamasında yürütülmüş ve tamamlanmıştır.

For Healthy participants * Male or female of \>=18 years of age inclusive, at the time of signing the ICF. * Certified as generally healthy by a comprehensive clinical assessment. Exclusion criteria: For AD participants * Previous treatment with dupilumab stopped within 6 months of baseline due to inadequate response to dupilumab. * Skin conditions other than AD that can confound assessments in the opinion of the investigator. * Regular use (\>2 visits per week) of a tanning booth/parlor within 4 weeks of the Screening Visit. * Severe concomitant illness(es) that, in the Investigator's judgment, would adversely affect the participant's participation in the study. * Participants with active tuberculosis (TB) or non-TB mycobacterial infection, or a history of incompletely treated TB unless it is well documented the participant has been adequately treated and can now start treatment with a biologic agent * Diagnosed with, suspected of, or at high risk of endoparasitic infection, and/or use of antiparasitic drug within 2 weeks before the Screening Visit (Visit 1) or during the Screening Period. * Active chronic or acute infection requiring treatment with systemic antibiotics, antivirals, or antifungals within 2 weeks before the Screening Visit (Visit 1) or during the Screening Period. * Known or suspected immunodeficiency, including history of invasive opportunistic infections. * Active malignancy or history of malignancy within 5 years before the Baseline Visit, except completely treated in situ carcinoma of the cervix and completely treated and resolved non-metastatic squamous or basal cell carcinoma of the skin. * Ocular disorder that in the opinion of the Investigator could adversely affect the individual's risk for study participation. Examples include, but are not limited to, individuals with a history of active cases of herpes keratitis, Sjogren's syndrome, keratoconjunctivitis sicca or dry eye syndrome that require daily use of supplemental lubrication or individuals with ocular conditions that require the use of ocular corticosteroids or cyclosporine. * History of systemic hypersensitivity or anaphylaxis to dupilumab or any other biologic therapy, including any excipient. * Participant with any other medical or psychological condition including relevant laboratory or electrocardiogram abnormalities at screening. For healthy participants * Regular use (\>2 visits per week) of a tanning booth/ parlor within 4 weeks of the Screening Visit. * Treatment with the following concomitant medications and procedures is prohibited within 4 weeks before the Screening Visit or 5 half-lives (whichever is longer) until End of Study Visit: * Topical medication * Analgesics * Immunomodulators * Antidepressants * Anti-anxiety drugs * Any Type 2 immune disorders uncontrolled Type 2 diabetes mellitus, Type 1 diabetes mellitus, neuropathy or any other neurological disease. * Any concomitant illness(es) or conditions that, in the Investigator's judgment, would adversely affect the participant's participation in the study or potentially affect any skin biopsy related read out. * Positive test for immunoglobulin E (IgE) antibodies.
