Filter by:This is an exploratory study to develop methodologies for the assessment of T-cell mediated therapies via skin immune challenges studies in healthy volunteers. The study will investigate what is the most appropriate; skin challenge agent, time and methodology to sample and characterise T-cells in the delayed type hypersensitivity (DTH) skin reaction. The skin challenge agents to be used in this study will be the neoantigen Keyhole Limpet Hemocyanin (KLH) and recall antigen Tuberculin Purified Protein Derivative (PPD). Part A of the study will assess an intradermal (ID) KLH challenge in three subjects to assess if the immune response to KLH is initiated by the innate or adaptive immune system. Each subject will receive one ID dose of 0.1 milligram (mg) KLH and will be assessed for a skin inflammatory response. Part B of the study will assess repeat ID challenges 28 days apart; the objective will be to characterise the T-cell response to each challenge and the kinetics of that response. For Cohorts 1A and 1B, 16 subjects will receive an initial subcutaneous (SC) 5 mg dose of KLH. Fifteen days later the subjects will receive 0.1 mg ID KLH dose and the response will then be assessed 48 and 120 hours after the initial challenge. The ID KLH challenge will then be repeated 28 days later and the response will be assessed at 48 hours (Cohort 1A, 8 subjects) and at 120 hours (Cohort 1B, 8 subjects) post challenge. For Cohort 2, a repeat challenge of either 2 tuberculin Unit (TU) or 10 TU ID PPD will be administered 28 days apart, to 8 subjects. The first challenge response will be assessed 48 and 120 hours post challenge. The second challenge will be administered 28 days after the first and will be assessed at the same timepoints. The repeat challenge 28 days later will allow an intra-subject analysis and will determine if a subject can be used as their own control. Part C of the study will assess repeat ID challenges of PPD and PBS; the objective will be to characterise the T-cell response to each challenge and the kinetics of that response. For Cohort 1, 6 subjects will receive a 0.1ml ID dose of PBS and another dose 24 hours later. Each challenge will be assessed 48 hours post challenge. Approximately 2 subjects will have an assessment of their normal skin as a control. For Cohort 2, a repeat challenge of either 2TU or 10TU ID PPD will be administered 28 days apart, to 6 subjects. The first challenge response will be assessed 48 post challenge. The second challenge will be administered 28 days after the 1st and will be assessed at the same timepoint. The repeat challenge 28 days later will allow an intra-subject analysis and will determine if a subject can be used as their own control. The total duration of this study for Part A is 14-18 days plus up to 30 days screening. The total duration of this study for Cohort 1A is 56-60 days plus up to 30 days screening. The total duration of this study for Cohort 1B is 59-63 days plus up to 30 days screening. The total duration of this study for Cohort 2 if 2TU is used is 45-49 days plus up to 30 day screening. The total duration of this study for Cohort 2 if 10TU is used is 48-51 days plus up to 30 days screening. The total duration of this study for Part C Cohort 1 is 15-19 days plus up to 30 day screening. The total duration of this study for Cohort 2 if 2TU is used is 42-46 days plus up to 30 day screening. The total duration of this study for Cohort 2 if 10TU is used is 45-49 days plus up to 30 days screening.
To demonstrate the ability of Aurstat to reduce pruritus in subjects with mild to moderate atopic dermatitis. Efficacy results will be based on subject assessment, IGA, and photographic evidence based on ordinal scales for tolerability.
Patients with atopic dermatitis treated with conventional treatment plus Dialyzed Leukocyte Extracts (DLE-oral Transferon) as adjuvant, have better clinical outcome than patients treated only with conventional treatment.
Occupational hand eczema (OHE) is a frequent disease which often takes a chronic course. The burden of the disease is high in a personal as well as in a socio-economic context. There is a need for evaluating new strategies to improve the prognosis for OHE patients. The objectives of the study is to evaluate the effect of group education on sick lave, health-related quality of life and disease severity among individuals with newly notified OHE. The trial population consist of individuals from the Capital Region of Denmark and Region Zealand with a suspected skin-related industrial injury notified to the Danish National Board of Industrial Injuries (DNBII). Recruitment is started Juli 2012, and will continue until the designed number of participants have been included. All participants will be assessed in a questionnaire at time T=0 with regard to: self evaluated disease severity, health-related quality of life, skin protective behaviour, knowledge of skin protection, self-efficacy, work-role function and if active in workforce. The participants will then be randomised. The intervention group will be invited to participate in the educative course, and work place visits will be offered. In the intervention group a telephone hot line will be available for further questions concerning these topics. The control group will not have access to any of these interventions. Both intervention group and control group will be contacted every eighth week about number of days of sick leave/absence from workforce. Both groups are re-assessed using a questionnaire at T=12 months. There will be a total of 742 included participants.
Our central hypothesis is that dietary limitations introduced by food allergy will contribute to increased food insecurity in households with food allergic children when compared to food insecure households without food allergic children.
The Polish Mother and Child Cohort is multicentre prospective study on different exposures. Prospective cohort study design enables identification of exposures that may influence pregnancy outcome and chil-dren's health, verification of such exposures by biomarker measurements and notification of any changes in exposure levels. The aim of the study is to evaluate the impact of exposure to different environmental factors during pregnancy and after birth on pregnancy outcome and children's health. Specific research hypotheses refer to the role of heavy metals, exposure to polycyclic aromatic hydrocar-bons (PAHs) and environmental tobacco smoke (ETS) in the aetiology of intrauterine growth retardation (IUGR), preterm delivery (PD) and the risk of respiratory diseases, allergy and poor mental and physical development. It is also intended to explain the role of oxidative stress and nutritional status of the pregnant women. The impact of occupational exposures and stressful situations on pregnancy outcome will be evaluated from question-naire data. The results of the study will help to determine levels of child prenatal and postnatal exposure in several areas of Poland and their im-pact on course and outcome of pregnancy and children's health. This protocol concerns the children that are followed-up from birth to the age of 2 years to determine long term effects of pre- and postnatal environmental exposures.
To assess the efficacy of multiple dupilumab (REGN668/SAR231893) dose-regimens, compared to placebo, in adult patients with moderate-to-severe atopic dermatitis (AD).
The purpose of this study is to evaluate the effect of topical roflumilast on the reduction of atopic dermatitis lesions in adults with atopic dermatitis.
The principle aim of this study is to obtain safety, tolerability and pharmacokinetic data when LEO 39652 cream is administered cutaneously as single dose to subjects with atopic dermatitis and to healthy subjects.
The objective of this study is to verify the non-inferiority of TAU-284 to ketotifen fumarate dry syrup in the change in the severity of pruritus after the treatment period.
