Filter by:This is a phase I, single-center, randomized, double-blind, dose escalation study without therapeutic benefit, in which PBF-680 will be administered as single oral ascending dose to young male healthy volunteers. Up to four different rising doses will be tested in groups of 8 participants. Thus, four groups will participate but each one participating only once. For each dose level / group the participants will be randomized to active or placebo with 2 participants being randomly assigned to placebo and 6 to the active drug. First, one volunteer will receive active drug (subgroup 1); after 48h of safety and tolerability assessment a second subgroup of 3 volunteers will receive 2 active drug and 1 placebo; after 48h of safety and tolerability parameters assessment a third subgroup of 4 volunteers will receive 3 active drug and 1 placebo. After evaluation of safety parameters of dose level the process will replicate one week afterwards in the following dosages. The aims of this study are: Primary: - To assess the safety and tolerability of single escalating oral doses of PBF-680 in young male healthy subjects leading to the determination of the maximum tolerated dose (MTD). Secondary: - To assess the pharmacokinetics of PBF-680 after single rising oral doses in healthy young male subjects. - To asses the preliminary pharmacodynamic effects. - To evaluate the adenosine A1 receptor antagonism in blood samples of healthy volunteer caused by the PBF-680 administration
The purpose of this study is to assess whether the risk of serious asthma-related events (asthma-related hospitalizations, asthma related intubations, and asthma related deaths) in adolescents and adults (12 years of age and older) taking inhaled formoterol fumarate/fluticasone propionate combination is the same as those taking inhaled fluticasone propionate alone.
The primary objective of this study is to compare the pharmacokinetic (PK) profiles of Albuterol Spiromax® and ProAir HFA after administration of a single inhaled dose of 180 mcg albuterol base from each product.
We want to examine the effect of multidisciplinary interventions in asthma patients who had experienced acute exacerbation of asthma. In our previous observational studies, elderly asthma patients had a some distinct features such as impairment of cognitive function, deficiency of micronutrient and absence of caregiver compared with young adult asthmatics. We wanted to evaluate whether the long-term course of asthma could be modified by intervening deficienies which were found in elderly patiensts. So, we designed a interventional study to correct above risk factors in elderly asthma patients, which could be aggravating their asthma. Followings are our specific multidiciplinary items that we want to correct. 1. popularize and educate the asthma action plan 2. run a emergency call system for acute exacerbation 3. educate the proper techniques using inhalers 4. correct the deficiency of magnesium (magnesium 500 mg per day) After 1 years, we will measure the numbers of acute exacerbations, lung function including FEV1 and FEV1/FVC, health-related quality of life and level of serum magnesium in study patients.
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.
The trial is an investigator-driven research study in subjects with intermittent asthma, the aim of which is to explore the likelihood of a functionally important separate leukotriene E4 (LTE4) receptor in airways and/or inflammatory cells in human subjects with asthma. Mostly on the basis of experiments in mice models, the prevailing view suggests that the present class of anti-leukotriene drugs are insufficient because they do not block the pro-inflammatory and bronchoconstrictive effects of LTE4. It is established by us and other groups that LTE4 is the most stable and long-lived leukotriene. The study will establish the effect of oral treatment with the highly selective CysLT1-receptor antagonist, montelukast, on bronchial responsiveness to inhaled LTE4 in subjects with intermittent asthma
The purpose of this study is to prospectively examine the relation between topical corticosteroid use and hair cortisol concentration, among patients with moderate persistent asthma or allergic rhinitis. The investigators hypothesize that patients with asthma or allergic rhinitis treated with topical corticosteroids (i.e. inhaled corticosteroids (ICS) or intranasal glucocorticoids (INGC)) have higher levels of hair cortisol after 3 months of treatment than during the 3 months prior to initiation of treatment.
The study will be a randomized, double-blind, placebo controlled cross-over study in 32 adult subjects with moderately severe asthma. In this study the bronchodilator effect of a single morning dosing of FF/VI combination 100/25 mcg will be determined by spirometry. After the screening the subject will be randomized and will be assigned to one of two treatment sequences (AB or BA, where A is placebo and B is FF/VI 100/25 mcg). Between the two treatment periods there will be a washout period of 7-14 days. A serial forced expiratory volume in one second (FEV1) measurements will be taken at 15, 30 minutes, 1, 2, 4, 12, 24, 36, 48, 60 and 72 hours post dose. Safety assessments will include vital signs, electrocardiograms (ECGs), adverse event (AE) monitoring and laboratory safety tests however, these will not constitute study endpoints. The results of the study will provide supporting information to prescribers on the bronchodilator effect of FF/VI over 72 hours.
The purpose of the study is to assess the clinical effect of QAW039 in non-atopic asthmatics taking low dose Inhaled Corticosteroid (ICS) as background therapy.
