Filter by: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.
Current asthma medicines include inhalers. A common type of inhaler is called a 'beta-agonist' (e.g. salbutamol). They improve asthma symptoms by stimulating areas in the airway causing it to widen. Although these drugs are useful short term, long term use can make asthma worse in some people. 'Beta-blockers' are the complete opposite type of medication. Just now they are avoided in patients with asthma. Beta-blockers cause problems in asthmatics in the short term, including severe asthma attacks. The other mainstay of inhaler treatment for asthma is inhaled steroid or 'preventer' medication. These work by dampening down the inflammation in the lungs that occurs in asthma. New research has suggested that longer term use of beta-blockers can also reduce airway inflammation which may improve asthma control. This research was done in asthmatic patients who didn't need inhaled steroids to control their asthma. At the moment the investigators are studying to see if there is a benefit of beta-blocker use for asthma over and above asthmatics own usual doses of inhaled steroids. In this study, the investigators will be trying to find out if adding a beta blocker to a smaller dose of steroid inhaler has the same effect on asthma control as just using a higher dose of steroid inhaler by itself.
The aim of this case-control study is the comparison of the cell distribution in induced sputum in young adults with asthma and in healthy controls. The study consists of two visits. At both visits subjects are asked to perform a lung function test (body plethysmography) and levels of exhaled nitric oxide (eNO) are measured. At the first visit a blood sample is drawn to determine the inflammatory and allergic status of the subjects and the sputum is induced by an ultrasonic nebulizer. At the second visit another sputum sample is induced by a nozzle nebulizer. The cell distribution will be evaluated in both sputum samples.
The purpose of this study is to optimise the device and/or formulation of the Fluticasone propionate (FP)/salmeterol (SALM) unit dose powder inhaler (Rotahaler) to achieve drug delivery characteristics comparable to the Fluticasone propionate /salmeterol DISKUS inhaler. The indication is asthma and chronic obstructive pulmonary disease. The study is an open-label, randomised, cross-over, single centre study in healthy volunteers and will be conducted in a maximum of 3 parts, A, B and C. The design is adaptive and pharmacokinetic (PK) data analysis follows each part to enable a decision on whether progression to the subsequent parts is required. Part A of the study will test an alternative version of the Rotahaler with a low airflow resistance. The study will then test one or more of the following options depending on the outcome of part A. If progressed, part B will test modified Rotacap formulations including: (1) modified blend formulation, (2) reduced capsule fill weights, (3) different capsule types. Part B will also test other versions of the Rotahaler with intermediate airflow resistance. Part C will test the lower strength FP/salmeterol (100/50 mcg or lower) and/or a new unit dose DPI device (BUDI). A total of 36 subjects will be enrolled in each part to ensure 32 complete. In each cross-over arm, subjects will be administered 7 doses (3.5 days bid) with PK sampling following administration of the 7th dose. A three-day minimum wash-out period will separate each cross-over arm.
There are new, very sensitive methods for detecting bacteria. These methods show that hundreds of millions of microbes (organisms that can only be seen with microscopes), especially bacteria, live in healthy people. The collection of different microbes found in a site is called a "microbiome." The investigators know that microbiomes of the skin, sinuses, mouth, gastro-intestinal tract, etc. differ from each other. The make-up of the microbiome - which bacteria are found in a site - may be necessary for good health. For example, the microbiome of the mouth is different in people with inflammation of the gums (periodontitis), and the microbiome of the bowel is different in people with inflammation of the intestinal tract (inflammatory bowel disease). The purpose of this research study is to find out if the microbiome in the lungs is different in healthy people without asthma compared to people with asthma. This study will also find out if the microbiome of the lungs changes when people with asthma take a daily "controller" medication called an inhaled corticosteroid.
The overall goal of the Asthma Inflammation Research [AIR] Translational Program is to create an integrated multidisciplinary team for the focused purpose of development of diagnostic and prognostic tests informative for airway inflammation, and for the design of innovative, targeted biologic therapeutics. The overarching aims of the AIR program are to conceptualize, develop, and test the next-generation therapeutics, and novel asthma diagnostic and prognostic tools that will allow us to improve the standard of asthma care.
There have been a number of studies which attribute causality between reflux disease and asthma. In addition, clinicians typically treat chronic asthmatics with high dose acid suppressing medications (e.g. lansoprazole). However, clinical trials only recently have shed some light on this dilemma, with recent studies suggesting that the association is not as clear. This "retrospective" analysis of a prospective study which treated mod-severe asthmatics with lansoprazole or placebo will enter the collected raw data into a database, then perform statistical analyses to determine if children with asthma treated with acid suppression improved their asthma compared to those receiving placebo.
The primary objectives of this study are: i. to determine the effect of single oral doses (20 and 200 mg) of ONO-6950 versus placebo on exercise induced bronchoconstriction (EIB) as percent attenuation in the decrease of forced expiratory volume in 1 second (FEV1) after exercise challenge ii. to determine the safety and tolerability of single dose administrations of 20 and 200 mg of ONO-6950 in asthmatic patients. The secondary objectives of this study are: i. to compare the effect of different (20 and 200 mg) single oral doses of ONO-6950 versus montelukast (10 mg) on EIB as percent attenuation in the decrease of FEV1 after exercise challenge ii. to determine the ratio of responders/non-responders in FEV1 for different (20 and 200 mg) single oral doses of ONO-6950 in comparison to montelukast (10 mg) and placebo.
The purpose of this pilot study is to collect preliminary clinical data related to the safety and preliminary clinical benefits of non-invasive vagal nerve stimulation with the AlphaCore™ device for the relief of acute bronchoconstriction due to asthma. Up to 30 subjects who meet all inclusion/exclusion criteria and consent to participate in the study may be enrolled at up to 5 investigational (study) sites. The study sites are clinic settings capable of treating any potential complications of bronchoconstriction, an acute exacerbation of asthma, and any emergencies associated with use of the investigational device.
