Filter by:Asthma is a chronic inflammatory bronchial disorder with three distinct components: airway hyper-responsiveness (respiratory hypersensitivity), airway inflammation, and intermittent airway obstruction. One of the characteristics of the disease is an inflammatory reaction of the immune system caused by cytokine production. A substantial number of asthma patients do not satisfactorily respond to steroid therapy and consequently have an unmet medical need for novel targeted therapies with improved specificity, tolerability, and compliance. Novel therapeutic strategies for the treatment of chronic inflammatory diseases by targeting early disease-causing mechanisms are a promising approach for the treatment of asthma. The transcription factor GATA-3 plays a key role in mediating the asthmatic immune response and has been shown to be necessary and sufficient for the production of cytokines interleukin (IL)-4, IL-5, and IL-13. The active principle hgd40 of the investigational medicinal product SB010 belongs to a new class of antisense oligonucleotide therapeutics, the 10-23 DNA (deoxyribonucleic acid)zymes (antisense oligonucleotide). DNAzymes are catalytically active nucleic acids that cleave complementary RNA (ribonucleic acid) molecules. By cleaving GATA-3 mRNA, hgd40 reduces specific cytokine production and thereby reduces key features of allergic airway inflammation. DNAzymes are generated completely by chemical synthesis and can be produced under Good Manufacturing Practice (GMP) controlled conditions. The DNAzymes are not biological drugs, i.e. they are not generated by use of any living organism including cell culture or bacteria. The molecules are highly water-soluble and will be applied as solution directly in their synthesized form. The current study will evaluate the safety and tolerability of increasing multiple doses of inhaled SB010 in healthy male subjects.
The purpose of this study is to estimate the prevalence of allergic diseases and atopy among patients with angiographically confirmed coronary artery disease as well as to assess levels of serum allergic inflammation markers in this population.
The primary objectives are - to determine the effect of ONO-6950 200 mg QD versus placebo administered for 8 days on early asthmatic response (EAR) and late asthmatic response (LAR) induced by inhaled allergen - to determine the safety and tolerability of ONO-6950 200 mg QD administered for 8 days in patients with asthma The secondary objectives are: - to compare the effect of ONO-6950 versus montelukast on the % decrease of FEV1 following allergen exposure, and - to determine the effect of ONO-6950 versus placebo and montelukast on allergen-induced airway hyperresponsiveness (AHR) as measured by methacholine challenge
This study will provide the clinicians guidance on the safest combination of inhaled and nasal corticosteroids for children with mild asthma and allergic rhinitis respectively; however, one safety concern is that these products are independently known to have dose-related effects on short term and intermediate term growth. Knemometry is a non invasive technique for measuring short-term lower leg growth in children and is currently the method of choice in growth studies of short duration. Subjects will be seen on a weekly basis for 18 weeks and at each visit, lower leg length will be measured using knemometry.
The purpose of this study is to study differences in small airways (<2mm) parameters in asthma patients, subjects with asymptomatic airway hyperresponsiveness and healthy controls.
Asthma is a disease of rapidly increasing incidence that already affects more than 17 million people in the United States alone. It has long been known that areas of severely reduced airflow occur in asthma and contribute significantly to the impairment of gas exchange in this disease. However, the extent to which local blood flow changes during an asthmatic attack is unclear. The purpose of this study is using Positron Emission Tomography - Computed Tomography imaging to evaluate how the blood flow changes in the lungs during an asthma attack induced by allergens.
This study will assess the safety and efficacy of QAW039 when added to current therapy in patients that have sputum eosinophilia and persistent asthma.
This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will assess the efficacy and safety of lebrikizumab in patients with asthma whose disease remains uncontrolled despite daily therapy with an inhaled corticosteroid and a second controller medication. Patients will be randomized in a 1:1:1:1 ratio to receive double-blind treatment with subcutaneous lebrikizumab ("highest", "middle", "lowest" dose) or placebo every 4 weeks for 52 weeks, in addition to their standard-of-care therapy. This will be followed by a 52-week double-blind active treatment extension. The anticipated time on study treatment is up to 104 weeks. There will be a safety follow-up of 24 weeks after the last dose of study drug for all patients.

The primary objective of the study is to determine whether the incidence of atopic asthma after three years old may be suppressed in the children who were born as preterm infants and prophylactically treated with palivizumab for respiratory syncytial (RS) virus infections during the infancy. The secondary objective is to determine whether the incidence of recurrent wheezing after three years old may be suppressed in the children who were born as preterm infants and prophylactically treated with palivizumab for RS virus infections during the infancy.
