Filter by:A phase 2, multicentre, randomized, double-blind, placebo-controlled, parallel group study to evaluate the effect of tezepelumab on airway inflammation in adults with inadequately controlled asthma.
Primary objective is to assess whether dupilumab as adjunct to AR101 compared to placebo improves desensitization at the completion of up-dosing, defined as an increase in the proportion of participants who pass a post up-dosing double-blind placebo-controlled food challenge (DBPCFC) at visit 16. Secondary objectives are: - To assess whether dupilumab as adjunct to AR101 compared to placebo improves desensitization at the completion of up-dosing, defined as an increase in the cumulative tolerated dose (log transformed) of peanut protein during a post up-dosing DBPCFC at visit 16 - To assess whether dupilumab as (indefinite [continuously]) adjunct to AR101 compared to placebo maintains desensitization, defined as an increase in the proportion of participants who pass a post maintenance DBPCFC at visit 22 - To assess whether dupilumab as (limited [previously]) adjunct to AR101 compared to placebo maintains desensitization, defined as an increase in the proportion of participants who pass a post maintenance DBPCFC at visit 22 - To evaluate the safety and tolerability of dupilumab as adjunct to AR101 compared to placebo - To assess the effect of dupilumab (compared to placebo) as adjunct to AR101 on the change in peanut-specific Immunoglobulin E (sIgE), Immunoglobulin G (IgG), Immunoglobulin G4 (IgG4), and peanut-specific IgG4/IgE ratio - To assess if dupilumab increases the tolerability of AR101 as measured by the daily symptoms (electronic diary [e-diary]) during the up-dosing phase
This protocol will help better define whether patients with peanut and/or tree nut food allergy can tolerate traces in products with precautionary allergen labelling.
Food allergy (FA) is a serious public health concern that causes potentially-life threatening reactions in affected patients. The prevalence of food allergy in the United States (U.S.) has increased substantially and now affects 15 million patients:4-8% of children (6 million children, 30% with multiple food allergies) and about 9% of adults. This is a prospective Phase 2, single-center, multi-allergen OIT study in participants with proven allergies to 2 or 3 different foods in which one must be a peanut. The total of participants in the clinical study will be 110, ages 4 to 55 years with a history of multiple food allergies of 2 to 3 different foods including peanut. Allergy will be confirmed by FA-specific IgE levels and positive skin prick test (SPT). Enrolled participants must be positive during the Double-blind Placebo-controlled Food challenge (DBPCFC) at or before the 300 mg (444 mg cumulative) dosing level of FA proteins.
The aim of this study is to evaluate the acceptability, feasibility and preliminary effects a GP_Posit intervention. GP_Posit is an intervention where mothers will learn how to participated in their preterm infant's care and positioning while being guided by a nurse. Preliminary effects will be estimated on maternal sensitivity, stress and anxiety as well as preterm infant's neurodevelopment.
The aim of this study was to study the level of high-sensitivity CRP in sera of pre-diabetic and newly diagnosed patients with type 2 diabetes mellitus and its correlation with HOMA IR and HbA1c
This is a phase III, single blind (outcome assessor is blinded), randomised controlled multicentre trial of the effect of EpiCeram emollient for improving and maintaining skin barrier function and reducing incidence of eczema and food allergy in high risk infants. A total of 760 participants with a first degree family history of allergic disease (asthma, eczema, allergic rhinitis or food allergy) will be recruited (380 each group) from maternity wards of three hospitals.
A cross-sectional quantitative study will be carried out; recruiting female, Caucasian participants aged 18-65 years. The relevance of candidate gene studies is disputed. Research has shown associations between genotype and total fat intake. However, food preference is often described as a result of exposure to food types during upbringing. Many single nucleotide polymorphisms (SNP) have been associated with fat taste sensitivity, the majority of research shows that with a reduced sensitivity comes a higher total fat consumption. This study aims to assess the relationship between rs1761667 genotype, body mass index, fat intake, fat taste sensitivity and fat taste preference.

Free fatty acids (FFA) are the main fuel source in a healthy adult heart, since they are responsible for 70-80% of the myocardial ATP production. Plasma FFA and triglycerides (TG) levels are elevated in obesity and diabetes, evoking substrate competition in the heart: the increased availability of lipids will lead to fat accumulation in the heart, which is associated with cardiac insulin resistance and will therefore restrain insulin-stimulated cardiac glucose oxidation. It is shown that a lower myocardial glucose uptake correlates with decreased diastolic function. The benefits of counterbalancing this lipid overload is proven by previous research in pre-diabetes, which showed the reversibility of impaired myocardial substrate metabolism and improvement of function and structure after modest weight loss induced by lifestyle changes. Ciprofibrates are a ligand of the peroxisome proliferator-activated receptor (PPAR) α and are considered to be a major regulator of the lipid metabolism and promote fat oxidative capacity. They are not only effective in normalizing lipid-lipoprotein levels in patients with the metabolic syndrome, but improve also their insulin sensitivity. We therefore hypothesize that ciprofibrate administration in subjects with impaired glucose metabolism (IGM) influence the myocardial substrate metabolism (via the PPARα pathway) and thereby improve myocardial insulin sensivity.
