Active clinical trials for "Asthma"

This study is a multicenter, stratified, randomized, active control, double-blinded, parallel-group comparative study with an open-label extension period. The study is designed to evaluate the efficacy and safety of FP/ SLM HFA MDI 50/25 microgram (mcg) one or two inhalation twice daily (BID) for 8 weeks in comparison with FP HFA MDI 50 mcg one or two inhalation BID, in 6-month to 4-year-old Japanese patients with bronchial asthma. The study is also designed to evaluate the safety of long-term treatment of FP/ SLM HFA MDI 50/25 mcg one or two BID for 16 weeks. The subjects meeting the eligibility criteria will enter the run-in period of 2 weeks and receive FP 50 mcg 1 or 2 inhalation bid (FP 100 or 200 mcg/day), before randomization. The subjects under 2 years of age at Visit 1 will receive only 1 inhalation bid during the run-in period. The subjects who meet the eligibility criteria for randomization will be stratified according to their age (<2 or >=2 year-old) at Visit 1 and randomized to one of the two treatment groups. The total duration of participation in the study will be 10 weeks for a comparison period completion and 27 weeks for a completion.

The investigators will perform a pilot study of daily treatment with oral sulforaphane (SFN) for 3 days to determine if Nuclear factor (erythroid-derived 2)-like 2 (NRF2) induction is possible with this supplementation regimen in individuals with allergic asthma.

This is a multi-centre, open-label long-term safety study of 100 milligram (mg) mepolizumab administered subcutaneously (SC) every 4 weeks for 12 months in addition to standard of care in subjects who have severe, refractory asthma and a history of eosinophilic inflammation. Subjects who completed either MEA115588 or MEA115575 will be offered the opportunity to consent for this study.

The major impact of this study will be to identify the adult severe asthma cohort that will benefit from supplemental L-arginine therapy. The investigators hypothesize that a subset of adult severe asthma patients will respond to supplemental L-arginine and derive clinical benefit from the addition of this therapy to standard-of-care asthma medications. The investigators hypothesize that the patients that benefit most will have low exhaled nitric oxide concentrations (< 20 ppb) at baseline.

This is a single centre, randomized, double-blind, placebo-controlled, single ascending dose study, in which the safety and pharmacokinetics of laninamivir octanoate administered by inhalation via the TwinCaps® DPI will be assessed in adults with mild or moderate chronic asthma.

Recent large clinical studies have demonstrated the interest of LAMA therapy in the management of asthma, when compared to LABA. V0162 is a compound with a very long lasting bronchodilator effect when compared to reference treatment in non-clinical models and in COPD patients. Secondary properties of V0162 (i.e.H1/H4 and PDE IV-inhibition) could enhance the efficacy of this antimuscarinic compound and could bring option in the treatment obstructive lung disease. The objective of the study is to assess the bronchodilator properties of V0162 during 8 days in adult patients with asthma usually treated with ICS and LABA. The study is a randomised, double-blind, placebo-controlled, 3-period crossover, preceded by an open-label active-control period before randomisation.

Control of airway inflammation is the cornerstone of asthma management. The aim of the present pilot study was to assess whether, and in which magnitude, a leukotriene receptor antagonist (LTRA) added to a basic treatment of inhaled corticosteroids (ICS) + long-acting betamimetics (LABA) might improve airway hyperresponsiveness and inflammation in well-controlled patients with asthma.

Rationale: Plant stanols are well known for their effects on lowering intestinal cholesterol absorption ultimately resulting in 10-15% reduced serum LDL cholesterol concentrations in humans. In addition we have also shown that serum triacylglycerol (TG) concentrations may be lowered in subjects with elevated baseline concentrations. Till now, there is little evidence for plant stanol effects other than improving lipid profiles. However, we have very recently found strong indications in ex vivo models using isolated human peripheral mononuclear blood cells (PBMCs) from healthy volunteers that plant stanols have the capacity to improve immune function. More into detail, plant stanols shifted the differentiation of naive T-cells into the Th1 direction by activating a specific receptor present on the Antigen presenting cells (APCs) and T-cells. This effect might ultimately be helpful in situations in which the Th1/Th2 cell balance is disturbed into a Th2 over-responsiveness. By activating the Th1 response, the disturbed balance may be restored. This is for example a possibility in the treatment or prevention of asthma, food allergies or HIV in susceptible subjects. In addition, very recently (MEC 08-3-051) in a pilot study we also showed these ex vivo Th1 stimulating effects of plant stanols specifically in PBMCs isolated from asthma patients, as said, a condition characterized by a Th2 dominant immune response. Objective: The major research objective is to prove that the consumption of plant stanol ester enriched yogurts can improve immune function in vivo in asthma patients. Study design: A double-blind randomized placebo-controlled human intervention study in which 90 patients with clinically proven asthma will participate: 45 in the intervention group receiving plant stanol yoghurt and 45 in the control group receiving a control yoghurt without added plant stanols. At the end of the run-in period as well as at the end of the experimental period blood will be sampled to isolate PBMCs. These cells are used to evaluate effects on cytokine production, phagocytic capacity of neutrophils, and the activity of NK cells. In addition, the golden standard to show improvements in immune function is by showing an elevated Immunoglobulin response to a vaccine. Therefore, during the experimental period all subjects receive a vaccination against Hepatitis A Virus. After 1, 2, 3, and 4 weeks blood will be sampled to monitor specific immunoglobulin titers to HAV. Study population: 90 people with clinically proven asthma, who are not carrier of hepatitis A, B or C and have not been vaccinated against hepatitis A in the past. Also, these participants do not have any other immune-related pathology Main study parameters/endpoints: primary: Specific anti-HAV antibody titers after vaccination; secondary: Phagocytic capacity of neutrophils; NK-cell activity; Th1 and Th2 cytokine production profiles by PHA stimulated PMBCs. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: During the study, 9 blood samples (each 20 or 50 mL) will be taken. Total time investment for the subjects will be 160 min. Occasionally, a heamatoma or bruise can occur during venipuncture. After the vaccination a heamatoma or a sore arm can occur. These side effects should disappear within 4-5 days. Other common side effects related to the vaccination are headache, loss of appetite, and fatigue, which usually will disappear within 24 hours. The results of this study will show whether consumption of plant stanol enriched yogurts is able to restore the disturbed th1/Th2 balance in asthma patients. Ultimately, this is expected to reduce asthmatic exacerbations, as the Th2 dominant immune response seems causal to asthmatic symptoms, however these clinical improvements are not verified in this relatively short term intervention study.

The purpose of this study is to evaluate the effect of MK-1029 on lung function in the treatment of adults who have persistent asthma that is uncontrolled with the use of montelukast (ML). Participants will use randomized study drug (either MK-1029 or placebo) for two separate 4-week treatment periods. All participants will also use ML during the treatment periods. The primary hypothesis is that MK-1029 is superior to placebo in change from baseline in forced expiratory volume in one second (FEV1) at the end of the 4-week treatment period.
