NCT06563102
The purpose of this study is to compare the efficacy and safety of albuterol/budesonide to albuterol in changes in airway inflammation, asthma symptoms, and rescue therapy utilization in adults with mild asthma. Study details include: * The study duration will be up to 15 weeks. * The treatment duration will be 12 weeks. * The visit frequency will be once every 4 weeks, with 3 clinic visits and 2 video calls in total.
NCT02892344
The purpose of the trial was to evaluate efficacy and safety of QMF149 150/80 microgram o.d. delivered via Concept1 compared to MF 200 microgram o.d., delivered via Twisthaler® in terms of lung function and symptom control in poorly (ie inadequately) controlled asthma patients. This study was to assess contribution of LABA as an add-on therapy to low dose ICS monotherapy.
NCT04912596
The objective of this study is to evaluate the pharmacodynamic (PD) bioequivalence (BE) of albuterol inhalers, test formulation: Albuterol Sulfate HFA inhalation aerosol 108 mcg (equal to albuterol base 90 mcg) per actuation and reference formulation: ProAir HFA (albuterol sulfate) or FDA authorized generic: Albuterol Sulfate HFA (Teva Pharmaceutical USA, Inc.) Inhalation Aerosol 108 mcg (equal to albuterol base 90 mcg) per actuation manufactured by two different manufacturers using methacholine bronchoprovocation challenge test in patients with stable mild asthma.
NCT06618105
This is a pharmacodynamic bioequivalence bronchoprovocation study using single-dose, double-blind, double-dummy, randomized, study consisting of four study treatments (zero dose \[Placebo\], E.Q. 90 mcg Base dose of R inhalation aerosol, E.Q. 180 mcg Base dose of R inhalation aerosol, E.Q. 90 mcg Base dose of T inhalation aerosol) and four Periods (Period 1 to Period 4). Randomization procedure at Period 1 will assign any one study treatment to be administered in each Period in a cross-over manner. By the end of Period 4, a subject who completes dosing in all four Periods would have administered all four treatments in the study. The efficacy variable, post-dose PC20 obtained during each Period is the provocative concentration of the methacholine challenge agent required to reduce the FEV1 by 20% following administration of differing doses of albuterol (or placebo) by inhalation. The 20% reduction in FEV1 is determined as compared to post-saline FEV1 measured before the Placebo or Albuterol administration. The pharmacodynamic equivalence will be based on the dose-scale method of analysis of the post-dose PC20 If the 90% confidence interval for the relative bioavailability (F) falls within 67.00% -150.00% then it will be considered that pharmacodynamic equivalence is established.
NCT04796844
The purpose of this registry aims is to collect a large number of patients with mild and moderate asthma in a real-word conditions for a perspective observation of epidemiological evolution of the disease in relation to the therapeutic interventions available currently and in the near future.
NCT00159302
This pilot study will measure the baseline levels and the intra- and inter-subject variability of exhaled (alveolar and bronchial) and nasal NO in smoking subjects with mild and moderate COPD on or off steroid treatment, smoking healthy volunteers and non-smoking mild asthmatics off steroids, using multiple exhalation flow rates.

NCT00448851
The purpose of this research study is to learn more about the effect of inhaled dust mite allergen extract on airway responses in allergic individuals with mild asthma. Information learned from this study will be used to identify a safe dose range of D Farinae extract for use in inhalation challenge studies. This study will also help determine how inhalation of the allergen affects mucociliary clearance (MCC) which is a measure of how quickly mucus clears from the airway.
