Active clinical trials for "Asthma"

Primary Objective: To evaluate the efficacy of dupilumab (SAR231893 / REGN668) in participants with persistent asthma. Secondary Objectives: To evaluate the safety and tolerability of dupilumab. To evaluate the effect of dupilumab on improving participant-reported outcomes including health-related quality of life. To evaluate dupilumab systemic exposure and incidence of anti-drug antibodies.

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.

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).

This study has a randomized multiple-dose, placebo-controlled, parallel group design consisting of a 2-week open placebo Run-in Period followed by a 6-week Treatment Period with placebo, test product (budesonide 80 microgram [μg]/formoterol fumarate dihydrate 4.5 μg), or reference product (Symbicort® inhalation aerosol).

Anthroposophic therapeutic speech is a complementary method that indirectly influences breathing and uses specific vowels, consonants, syllables and metres depending on the indication. The aim of this study is to test the effectiveness of anthroposophic therapeutic speech in patients with asthma regarding clinical and physiological parameters, asthma control and quality of life.

This study will be conducted to evaluate the effect of once daily treatment with fluticasone furoate (FF) on lower leg growth in pediatric subjects with persistent asthma by using knemometry. Approximately 65 paediatric asthmatic subjects, aged 5 to 11 years (inclusive), will be screened to achieve 60 randomised and 50 evaluable subjects. Subjects meeting the eligibility criteria will enter the 2 week run-in period. After completing run-in period, each subject will be randomly allocated to one of two treatment sequences: inhaled fluticasone furoate followed by placebo or placebo followed by inhaled fluticasone furoate. Each treatment will be administered via the ELLIPTA™ dry powder inhaler. The two treatment periods will be separated by a two-week wash-out period. Subjects completing two treatment period will enter into 7 days follow-up period. ARNUITY™ ELLIPTA (FF) is approved in the US for adults and adolescents aged 12 and above. ARNUITY and ELLIPTA are a registered trademarks of the GlaxoSmithKline group of companies.

The purpose of this study is to examine whether a parental training program using group-based Acceptance and Commitment Therapy for childhood asthma care, is effective in reducing the children's unplanned health care services utilization and asthmatic symptoms.

This study is a randomized, double-blind, placebo-controlled, three-period cross-over study in approximately 54 subjects with asthma.

The project is intended to be realised in two phases. In the first stage, a case control study will be performed. In the second phase, double-blind, placebo controlled study will be conducted. In the first phase 3 groups of children will be compare: i) a group of children suffering from chronic rhinosinusitis (CRS) (fulfilling the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) criteria) and asthma (fulfilling the Asthma Predictive Index (API) criteria) (CRS+/asthma+, n=90), ii) a group of children suffering from CRS (fulfilling the EPOS criteria) but without asthma symptoms (negative API criteria) (CRS+/asthma-, n=30) and iii) a group of children without symptoms of CRS (negative EPOS criteria) and without asthma symptoms (negative API criteria) (CRS-/asthma-, n=30). In the second phase the effect of intranasal glucocorticosteroids will be assessed. The following research methods will be used: CRS-symptom score questionnaire (SN-5) and Childhood Asthma Control Test (cACT) questionnaires, skin prick test, spirometry, measurement of nitric oxide NO in exhaled breath (FeNO), taste perception test, eosinophil morphology assessment, ratio: glucose concentration in nasal secretion/serum glucose level, concentration of specific immunoglobulin (Ig) E, total immunoglobulin G (IgG) and immunoglobulin A (IgA), the proportion of innate lymphoid cells (ILC) and regulatory lymphocytes cells in the peripheral blood. Endoscopic examination of the upper airways will be performed and samples of the mucosa will be taken. The mucosal examination will be as follows: i) polymerase chain reaction (PCR) examination for the detection of the presence of viral and bacterial genetic material, ii) measurement of the expression of the various messenger ribonucleic acid (mRNA), iii) measurement of the expression of mRNA for the Epithelial-Mesenchymal Transition (EMT) genes and iv) percentage of ILCs.

This study will evaluate whether treatment with L-citrulline, which is an amino acid found in some foods, can increase levels of L-arginine and thereby restore the concentration of nitric oxide (NO) in the airways.
