Filter by:This study is a phase 3, randomized, double blind and vehicle study to evaluate the efficacy and safety of Crisaborole ointment, 2% in Chinese and Japanese subjects with mild to moderate atopic dermatitis involving at least 5% treatable BSA. Eligible subjects will be randomized in a 2:1 ratio to one of 2 treatment groups (Crisaborole BID, Vehicle BID, respectively).
The utility of functionally relevant signature genes in assessing the clinical outcomes of dupilumab treatment in the adult onset atopic dermatitis
The role of vitamin D is well known in calcium and phosphate homeostasis; however, in addition to traditional functions, vitamin D has an important role in pathogenesis of different allergic diseases, such as asthma, atopic dermatitis (AD), and food allergy. There are evidences that lower cord blood vitamin D status is observed in infants with eczema. More-over, vitamin D level is decreased in subjects with asthma. One of the most important functions of vitamin D is to modulate the immune system response, both innate and adaptive, by suppressing Th2-type response and increasing natural killer cells. Vitamin D induces a higher level of IL-10, which is known as anti-inflammatory cytokine. Other studies have shown that vitamin D contributes to the conversion of CD4+ T cells to T regulatory cells. Recent studies showed that higher serum 25-hydroxyvitamin D level was associated with a reduced risk of asthma exacerbation and hospitalization. Vitamin D can enhance dexamethasone-induced MAP kinase phosphatase-1 (MKP-1) expression in peripheral blood mononuclear cells. Experimental data suggest that vitamin D can potentially increase the therapeutic response to glucocorticoid and can be used as an add-on treatment in steroid-resistant asthmatics. Vitamin D stimulates the production and regulation of skin antimicrobial peptides, such as cathelicidins, which have both direct antimicrobial activity and induced host cellular response by triggering cytokine release. Recent evidence suggests that low blood vitamin D level is a risk factor for food allergy. Vitamin D acts by binding to the vitamin D receptors (VDRs), which are located in a variety of tissues. VDRs have been identified on nearly all cells of the immune system including T cells, B cells, neutrophils, macrophages, and dendritic cells (DCs). Vitamin D deficiency predisposes to gastrointestinal infections by changing gut micro-biota, which may promote the development of food allergy. However the detail mechanism how vitamin D affects or protects the development of allergic diseases is still unknown. Vitamin D level is determined by sun exposure. Due to the fact that Lithuania, Latvia and Taiwan are located in different latitudes of north hemisphere with markedly different sun exposure, in this Joint collaboration study between Taiwan, Lithuanian and Latvia, we are going to study, (1). Serum vitamin D level in children and adults with AD and/or asthma in Lithuania, Latvia and Taiwan. (2). VDRs genetic polymorphisms of AD and/or asthma in children and adults in Lithuania, Latvia and Taiwan. (3). Finally, we would like to explore the gut microbiome of patients with AD and/or asthma in Lithuanian, Latvian and Taiwanese children and adults; and to estimate possible relationship between gut microbiome and vitamin D level and VDRs genetic polymorphisms. We believe that this study will be the first which compares the populations with different geographical and ecological factors having the same allergic diseases. We hope that these results will provide the answer about the role of vitamin D in the prevention, or in the future, in treatment of allergic diseases.
Assess Hemay808 concentration of 1%/3%/7% for treatment of mild and moderate adult atopic dermatitis patients.
The primary objective of this randomized trial is to determine whether comprehensive, accessible, and animation-style videos are a more effective method of therapeutic patient education (TPE) based on clinical outcomes than paper handouts in Spanish and English-speaking communities. The clinical outcomes being measured are the severity, sleep affected by atopic dermatitis (AD), and the amount of itch experienced.
This is a randomized, double-blind, double-dummy, active-controlled, multi-center study to assess the efficacy and safety of abrocitinib 200 mg (2 x 100 mg tablets) administered orally QD compared with dupilumab 300 mg administered by subcutaneous injection every other week (as per label guidelines) in adult participants on background topical therapy, with moderate to severe AD. The treatment duration is 26 weeks. A total of approximately 600 participants will be enrolled from approximately 220 sites globally. Approximately 600 participants will be randomly assigned to study intervention. There are primary efficacy assessments at Week 2 and Week 4, and a key secondary efficacy assessment at Week 16. Efficacy and safety endpoints will be assessed throughout the entire study. Exploratory endpoints related to hand eczema efficacy will be assessed throughout the study.
This is a Phase 2 randomized, double-blind, parallel group, vehicle-controlled study to evaluate the safety and efficacy of topical ATx201 OINTMENT in adolescents and adults with mild to moderate Atopic Dermatitis
Immune-mediated inflammatory diseases (IMIDs) most often affect young patients and have high impact on morbidity and mortality with a significant alteration in the quality of life of patients with professional, social and emotional repercussions. Beyond this burden, IMIDs share many common pathophysiological mechanisms and treatments, known as "targeted therapies". Despite progress in this field, much remains to be done in clinical, therapeutic and fundamental research to address the efficacy, resistance and side-effects of treatment. These similarities between IMIDs have led the FHU IMMINeNT to propose the creation of a prospective, multidisciplinary clinical-biological database (IMMINeNT cohort), associated to a biobank, of patients with IMIDs. The main objectives of this database will be to identify new prognostic and therapeutic biomarkers in order to develop new therapeutic targets and biomarkers, to identify prognostic factors and determinants related to the activity, severity and quality of life of patients with IMIDs as well as to the response and tolerance to treatment.
Purpose: To study the etiology and the epigenetic pathways leading to and regulating chronic itch. Similarly, to examine the mechanisms underlying skin changes, including epigenetic alterations while also testing the efficacy of opioid antagonists in atopic dermatitis. In this study, the investigators aim to examine chronic sensory disorder mechanisms related to chronic itch.
Skin barrier impairment and familial atopy have been implicated as crucial risk factors for the development of atopic dermatitis (AD). Additional risk factors have been explored, including gestational weight, height, age, familial smoking habits, proximity to urban centers and others. However, a comprehensive study focusing on the entire spectrum of risk factors has yet to be undertaken. Such a study could enable predictive capabilities able to inform medical professionals as to a newborn's inherent risk to develop AD, and potentially recommend appropriate preventative modalities to prevent or delay disease onset.
