What is the goal of this study? The goal of this clinical trial is to find out whether the study drug LQ036 (a nebulized solution taken by inhaling through a nebulizer) works to improve lung function and asthma control in people whose asthma is not well controlled. The study will also learn about the safety of LQ036, how the body processes it, and whether the body develops an immune response to it. What are the main questions? The most important question is: • Does LQ036 improve lung function (measured by FEV₁ - the amount of air you can blow out in one second) more than a placebo at Week 12? Other important questions include: * Does LQ036 improve lung function at other time points (weeks 1, 2, 4, 8, 16, 20, 24)? * Does LQ036 reduce asthma attacks (sudden worsening of asthma that needs extra treatment)? * Does LQ036 help people use less rescue medication (inhaler for quick relief) and have more days without asthma symptoms? * Does LQ036 improve scores on asthma control and quality of life questionnaires? * What medical problems do participants have when taking LQ036?

Background: "Remission" is a primary therapeutic goal in severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP), though definitions vary regarding olfactory function. We evaluated "Dual Remission" kinetics in patients treated with dupilumab over 24 months. Methods: This single-center retrospective study analyzed 28 patients with comorbid severe asthma and CRSwNP. Dual Remission was defined as simultaneous asthma remission (Asthma Control Test (ACT) ≥ 20, no exacerbations, no oral corticosteroids (OCS) and stable lung function) and CRSwNP remission (Sino-Nasal Outcome Test-22 (SNOT-22) \< 40, Nasal Polyp Score (NPS) \> 1). We additionally analyzed "Complete Recovery" by applying a stricter composite definition requiring the restoration of normosmia (Sniffin' Sticks score \> 12). Results: At baseline, patients exhibited uncontrolled disease (median ACT 19, NPS 6). Treatment led to rapid asthma remission (85.7% at 12 months, 100% at 24 months). CRSwNP remission was slower but progressive, rising from 57% at 12 months to 88% at 24 months, demonstrating a significant "catch-up" phenomenon. Consequently, Dual Remission rates increased from 54% to 88% by month 24. When applying the stricter "Complete Recovery" criteria requiring normosmia, only 32% met the goal. Conclusion: Dupilumab is highly effective, enabling 88% of patients to achieve Dual Remission after 24 months. However, full olfactory restitution is distinct from structural polyp regression and harder to achieve, likely due to persistent neuroepithelial damage.

Asthma is a common inflammatory respiratory disease affecting 11% of Canadians, but its diagnosis remains challenging, leading to delays in treatment or overtreatment. Spirometry with a reversibility test and bronchial provocation testing (BPT), considered the gold standard, are the reference diagnostic methods. However, access to BPT is limited as it is performed in hospital settings. Type 2 inflammation biomarkers, the fractional exhaled nitric oxide (FeNO) and blood eosinophils (EOS), represent a potential alternative. In addition to their prognostic and theragnostic value, these markers predict a good response to inhaled corticosteroids in individuals aged ≥ 6 years with asthma. However, their use remains restricted to pulmonologists in specialized clinics and is not recommended as a diagnostic tool in Quebec. Despite studies demonstrating their diagnostic value in specialized settings, these tests remain underexplored in primary care and insufficiently studied in children under 12 years. The objective of ou study is to evaluate the relevance and performance of FeNO and blood eosinophils in the diagnosis of asthma in children referred in primary care with non-diagnostic spirometry.
NCT04680117
The primary objective of this project is to extensively characterize the endotypes of pre-schoolers (0 to 6 years) and school-age children (6 to 12 years) with SA using an integrated approach, combining a description of their phenotype (asthma symptoms, atopy, and lung function) associated with histological (airway inflammation and remodelling), immune (innate and adaptive immunity), metabolomics, and microbiota analyses. This goal shall be achieved by an unsupervised in-depth analysis of patients requiring bronchial endoscopy, with bronchial alveolar lavage (BAL) and bronchial biopsy, as part of their clinical assessment.

NCT05059210
The goal of this study is to evaluate the implementation of the Coach McLungsSM shared decision making (SDM) intervention into primary care across a large healthcare system. Coach McLungsSM is a virtual evidence-based asthma intervention with built-in asthma education and clinical decision support. All asthma patients aged 5-17 who attend these practices will be assessed for uncontrolled asthma. Asthma exacerbations attributed to emergency department visits, hospitalizations, and oral steroid use, will be evaluated to serve as surrogate measures for patient-centered asthma outcomes.
NCT00001888
Fiberoptic bronchoscopy is a procedure which involves passing a pencil-thin tube into the lung in order to collect fluid and cells from the airways. Fiberoptic bronchoscopy can collect cells from the walls of airways by gently brushing them (bronchial brushing). In addition, squirting small amounts of sterile water in to the airway and gently suctioning it back into the bronchoscope (bronchoalveolar lavage) collects cells. In this study, researchers plan to perform these tests on patients with asthma and normal volunteers. This research may help to improve the understanding of the processes involved in airway inflammation and asthma....

NCT07071194
Asthma is a common respiratory condition that can be difficult to control despite the use of medications such as inhalers, oral steroids or even injectable medications. Osteopathic Manipulative Treatment (OMT) is a hands-on technique used to improve the chest structure and function and may help in improving breathing. Previous research showed that OMT in asthma patients, can improve the movement of the ribs and improve the "peak flow" which is the maximum rate at which a person can exhale air after taking a deep breath. However, no studies have evaluated the impact of OMT on lung inflammation. This single-site research study at University Hospitals aims to evaluate whether Osteopathic Manipulative Treatment (OMT) can reduce lung inflammation and improve breathing and lung function in adult patients with asthma. The lung function will be evaluated by Spirometry which is a test that measures how much air you can breathe in and out of your lungs, as well as how quickly and easily you can exhale air. The lung inflammation will be measured using a device that can detect how much you are breathing out Nitric Oxide which is a gas produced by inflamed cells in the lungs, this test is called: Fractional exhaled Nitric Oxide or FeNO. Approximately 100 participants will be enrolled.

This study was a prospective, interventional, pilot clinical study conducted over 3 months on cirrhotic patients with overactive bladder and asthma, evaluating the real-world applicability of selected PBPK-guided dosing regimens. Patients were stratified according to Child-Pugh class (CP-A, CP-B, and CP-C) and administered mirabegron and montelukast at doses corresponding to the closest commercially available strengths to Simcyp®-optimized doses. Clinical evaluation included number of incontinence episodes, number of micturation, volume voided per micturation, cough, and wheezing. Routine laboratory investigations were conducted to assess efficacy and safety and included liver function tests (serum albumin, total bilirubin, alanine aminotransferase \[ALT\], and aspartate aminotransferase \[AST\]), kidney function tests (serum creatinine and blood urea nitrogen \[BUN\]), and CBC.
NCT05440656
Severe eosinophilic asthma (SEA) is associated with poor disease control and compromised health-related quality of life (HRQoL), leading to a substantial psychosocial and economic disease burden. Benralizumab (Fasenra®), an interleukin (IL)-5-alpha receptor monoclonal antibody, is approved as an add-on maintenance treatment for SEA. This study aims at collecting real-world data that extend beyond the clinical effectiveness of benralizumab to the participant-reported impact of treatment on their HRQoL, sleep quality, depression, anxiety, work productivity and activity impairment, but also on treatment effectiveness. Recent technological advances in portable spirometers and wearable activity trackers (WAT) to increase physical activity for participants with asthma, even for older participants, allow this study to collect data on lung function parameters and physical activity from such devices for the first time at a country level in Greece. Using a multi-aspect approach, this study will generate real-world evidence on a broad range of both well-established clinical and novel patient-centered outcomes which are critical to the assessment of the therapeutic benefit both from the physician's and the participant's perspective. All main study outcomes will be examined at various timepoints throughout the course of the 48-week observation period, starting as early as 4 weeks after treatment initiation, thus enabling the identification of 'early' treatment responders with a closer focus on patients' physical and psychological well-being and HRQoL in addition to asthma control and lung function metrics
