7 Clinical Trials for Various Conditions
The purpose of the study was to assess the clinical effect of QAW039 in non-atopic asthmatics taking low dose Inhaled Corticosteroid (ICS) as background therapy.
The purpose of this study is to determine if a simple blood test can help in disease management, particularly asthma. This will be researched by looking at certain features of the blood and to compare asthmatics without allergies to those that have allergy-induced asthma.
Most children with asthma have concurrent atopy (allergic inflammation), which is associated with an improved response to ICS. However, the absence of an atopic phenotype is associated with a poorer ICS response, leaving clinicians with limited treatment options. The nonatopic asthma phenotype has been characterized as the absence of atopic diseases including allergic rhinitis, eczema, or food allergies, and a negative skin prick test to common aeroallergens. Children with mild asthma treated with ICS over 44 weeks without a positive allergen skin test are 3 times more likely to have an asthma exacerbation when compared with children with positive skin tests. Similarly, adolescents and adults with asthma with low blood eosinophils or low sputum eosinophils have no difference in exacerbation rate response to ICS compared with placebo. Due to poor ICS response in nonatopic children and the known adverse effects of ICS, the development of non-steroid treatments options is needed. Monotherapy with the long-acting muscarinic antagonist, tiotropium, was superior to placebo for treatment failure outcomes in adolescents and adults with low sputum eosinophil levels. Tiotropium is approved in children as an add on therapy to ICS in children ≥ 6 years with asthma. But, this combination of treatment would still expose children with nonatopic asthma to the risks (but potentially without the benefit) of ICS therapy. The objective of this study is to conduct a feasibility pilot safety study of 6-weeks treatment with tiotropium monotherapy vs. ICS in children ages 6 to 11 years old with nonatopic mild persistent asthma.
This Phase IIa, multicenter, randomized, double-blind, placebo-controlled, crossover study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamic (PD) effects of GDC-6599 compared with placebo in patients with a history of chronic cough.
This protocol is designed to provide blood, buccal mucosa and bone marrow aspirate samples from approximately 250, healthy volunteer donors for use in in vitro studies of mast cells, mastocytosis, and allergic diseases. Non-atopic donors will be recruited to donate blood, bone marrow, and/or buccal mucosa samples using conventional techniques. The investigational nature of the studies in which their blood, bone marrow and buccal mucosa samples will be used, as well as the risks and benefits of the donation process will be explained to all donors, and a signed informed consent document will be obtained. Donors will be compensated according to an established schedule based on the duration and discomfort of the donations. Samples provided through this protocol will be used solely for in vitro research. Blood, bone marrow, and buccal mucosa samples will be assigned a unique product number and the study investigators listed on this protocol will serve as the custodians of the code that links the product with a donor s identity. The nature of the in vitro studies in which the blood collected in this study will be used is not the subject of this protocol and will be described in general terms only. The samples will be used in several Institutional Review Board (IRB)-approved Laboratory of Allergic Diseases (LAD) protocols. This protocol is designed to assure adequate and complete informed consent, counseling, and protection of the study subjects according to IRB, Office of Human Subjects Research (OHSR), Office for Human Research Protections (OHRP) and other applicable Federal regulatory standards.
This is a prospective, single center, clinical mechanistic pilot clinical research study. Participants will not receive any investigational agent. The investigators will examine whether children with atopic dermatitis (AD) and food allergy have a different skin barrier, microbiome, epidermal transcriptome, and epidermal lipid composition than children with AD and no food allergy and non-atopic (NA) children. Participation involves a single study visit.
The purpose of this study is to look at how defects in the skin barrier and immune response affect risk for skin infections. Participants will be classified into 4 groups based on Atopic Dermatitis (AD)/Non-Atopic (NA) status and Staphylococcus aureus (S. aureus) colonization (negative or positive): * AD S. aureus negative * AD S. aureus positive * NA S. aureus negative and * NA S. aureus positive.
