Filter by:A phase III study to assess the efficacy and safety of sublingual immunotherapy with STALORAL dust mites solution compared with placebo for reduction of asthma symptoms.
This trial has been designed to evaluate the efficacy of specific immunotherapy with SLITone Dermatophagoides mix compared with placebo in subjects with house dust mite allergic asthma, based on asthma medication use during a period of 2 months with a high environmental exposure to mites (autumn 2008).
Efficacy and Safety from a high-dosed sublingual grass pollen preparation
This study is looking for allergic asthmatics. Lung and allergy testing will be done to verify. If qualified, blood will be drawn for laboratory studies.
Na-ASP-2 is a protein expressed during the larval stage of the N. americanus hookworm life cycle. In a clinical study in previously hookworm-infected adults in Brazil, this protein induced urticarial reactions (rash) in a subset of volunteers. This study will evaluate solutions of varying concentrations of the protein in both a skin prick-puncture and intradermal test that will eventually be used to screen volunteers living in hookworm endemic areas who are being considered as potential participants in vaccine trials, to reduce the potential of inducing allergic reactions in those vaccinated with the Na-ASP-2 Hookworm Vaccine.
This purpose of this study is to determine the efficacy and safety of a grass sublingual (under-the-tongue) tablet.
This study will evaluate and follow patients with various allergic, hypersensitivity and inflammatory disorders. The protocol is not designed to test new treatments; patients will be managed with standard of care therapies. Participants may be referred to other current NIAID protocols as appropriate or to new studies as they are developed, but will not be required to join another study. Patients with allergic, hypersensitivity or inflammatory disorders between the ages of 3 years and 80 years may be eligible for this study. Conditions of interest include, but are not limited to, asthma, allergic rhinitis, mastocytosis, atopic dermatitis and food allergy. Participants will have a medical history and physical examination, plus standard tests for diagnosing and treating their specific disorder. Tests may include routine blood and urine studies, X-rays or other imaging studies, allergy skin tests and lung function tests. Blood samples may be collected for research on immune system cells and other substances involved in immune function. Generally, about 2 to 6 tablespoons will be drawn at a time, but no more than 16 ounces will be collected over a 6-week period. NIH does not provide emergency medical treatment or treatment for other, unrelated conditions the patient may have. Therefore, patients must maintain a personal physician for these purposes.
Efficacy and Safety from a recombinant folding variant of Bet v 1
The purpose of the study is to investigate the efficacy and safety of a grass sublingual tablet in children and adolescents with a history of grass-pollen induced rhinoconjunctivitis with or without asthma.
Compare the effect of a single dose of fexofenadine HCl 180 mg plus orange juice versus placebo plus orange juice on the change from baseline (pre-dose) in histamine skin flares.
