Filter by:The purpose of this study is to answer the question whether a disease-specific profile of breath in patients with asthma can be detected by an untargeted metabolomic study using exhaled breath analysis by mass spectrometry.
A Multicentre, Randomized, Double-blind, Parallel Group, Placebo Controlled, 12-Week, Phase 2 Study to Evaluate the Effect of Tralokinumab on Airway Inflammation in Adults with Asthma Inadequately Controlled on Inhaled Corticosteroid.
Metered Dose Inhaler (MDI) and Dry Powdered Inhaler (DPI) are the two most common devices used to deliver medicine in conditions such as asthma and chronic obstructive pulmonary disease. It is well-known that most patients do not use correct technique when using a metered dose inhaler. This leads to poor control of their disease. This study is being done so the investigators can record the patient using the metered dose inhaler before and after a short teaching session. This information will be fed into an invitro system (device) to allow the researchers to study the effect of error on drug delivery. The device being used is the Rice R3 electronic flowmeter.
The combination of FF, an ICS and VI, an orally inhaled LABA has been developed as a once-daily combination therapy for the long-term maintenance treatment of asthma in adults and children >=12 years of age. Pivotal phase III studies have demonstrated the safety and efficacy of FF/VI in asthma. However, it is increasingly acknowledged that randomised clinical trials tend to be highly controlled and enrol a more highly selected subject population than is expected to be prescribed the medication post-approval. There is a need for data in a more representative population in close to a 'real life' conditions, where physicians have the ability to choose the best treatment in their view for any individual subject and adapt treatments to subjects' characteristics and response. This multi-center, open-label, randomized, parallel group study will evaluate the efficacy and safety of FF/VI compared with two usual ICS/LABA fixed combination (fluticasone propionate/salmeterol [FP/S] or budesonide/formoterol [BUD/F]) in subjects with persistent asthma, in a "close to real life" settings. FF/VI will be administered once-daily (QD) via ELLIPTA dry powder inhaler (DPI) and FP/S or BUD/F will be administered twice daily (BID) via DISKUS™ and TURBUHALER™ DPI respectively. ELLIPTA is a new powder inhaler designed to be easy to use. The total duration of subject participation will be approximately 6 months (24 weeks). ELLIPTA and DISKUS are registered trademarks of the GSK group of companies. TURBUHALER is a registered trademark of AstraZeneca.
The objectives of this trial are primarily to evaluate the efficacy and safety of BI 655066/ABBV-066 (risankizumab) as compared to placebo over a 24-week treatment period in severe asthma patients. The primary endpoint is time to first asthma worsening during the planned 24 week treatment period for active vs. placebo treated patients on top of standard of care therapy. Upon demonstration of a meaningful clinical response, another important objective is the identification of biomarkers that can be used to target patients who will likely respond to treatment with BI 655066/ABBV-066 (risankizumab).
Each patient will participate in the study for approximately 7 weeks. Participation will include a screening period of up to 21 days and 4 treatment periods; each consisting of a 3-day/2-night inpatient period.
This study will examine the hypothesis that in obese asthmatics; treatment with NOx + CLA is well tolerated, safe and will increase eNO while reducing airway oxidative stress. Allied with this, the investigators will define whether supplementing with this bioactive mediator modifies the airway microbiome, and reduces airway inflammation.
Epidemiological and observational studies have linked vitamin D deficiency with increased asthma/allergy incidence . Vitamin D insufficiency (<75nmol/L) has been associated with increased incidence of severe childhood asthma. Further, high 25(OH)D levels were associated with reduced risk of recent hospitalization, lower use of anti-asthmatic medication and lower airway hyper-responsiveness in childhood asthmatics. The association between vitamin D and allergy and asthma appears to be stronger in children than adults, with some even suggesting that childhood asthma may may be caused by VDD.
Inflammation of the nasal and bronchial mucosa characterizing rhinitis and asthma are probably manifestations of the same disease. Multiple functional observations, pathogenic and clinical support that assertion. It is noteworthy that most asthma patients, who underwent a nasal endoscopic polypectomy, improve your asthma after surgery. This improvement would be related to the administration of oral steroids that these patients usually receive after surgery, or the disappearance of nasal discomfort caused by nasal polyps to improve ventilation. But this does not explain why this improvement, in some cases lasting for months after the operation, and without receiving oral steroids. It is speculated that severe nasal inflammation due to nasal polyps stimulate the bone marrow to produce more eosinophils, an increased supply of blood eosinophils, and consequently, a major bronchial eosinophilic inflammation, aggravating asthma. However, it is noteworthy that studies have evaluated the clinical impact in asthma after endoscopic nasal polypectomy, are scarce or performed on a small number of cases, the results are inconsistent and do not allow categorically whether or not such positive association. And more importantly, none of them included measurements of airway inflammation and hypothesized relationship between bronchial eosinophilic inflammation and nasal polyposis, aclarar.La remains finding that provides nasal endoscopic polypectomy objective improvement of severe asthma it could be a future therapeutic option to consider in patients with asthma and rhinosinusal polyposis.
The number of people with of asthma and allergy is still increasing and a large number of patients still do not have their asthma well controlled. There is therefore a need for new asthma treatments that work well and have less side effects. The study compares a new experimental drug RPL554 with a marketed asthma drug (salbutamol) and placebo.
