TriMaximize: A Multicentre, Prospective, Non-interventional Trial in Asthma Patients

The goals of asthma therapy for all degrees of disease severity are minimising asthma symptoms, maximising lung function, and preventing asthma exacer-bations. Despite the existing treatment options and differentiated guidelines, 35 % to 45 % of the GINA 4/5 patients suffer from inadequately controlled symptoms. To investigate the cause of unsatisfactory treatment results, it is essential to monitor therapy pathways of asthma patients in a real-world set-ting. Resulting data can be compared to therapy guidelines and generate hy-potheses for future clinical trials. Trimbow® is a fixed triple therapy containing a long-acting muscarinic antago-nist (LAMA, glycopyrronium), a long-acting beta-adrenergic agonist (LABA, formoterol) and an inhaled corticosteroid (ICS, beclomethasone). Trimbow® MS (medium strength) contains 100 µg beclomethasone whereas Trimbow® HS (high strength) contains 200 µg beclomethasone. Both formulations are investigated in this study. Trimbow® has shown major clinical benefits in randomised controlled trials. However, the effects of Trimbow® on changes in patients' symptom burden and quality of life, adherence and clinical outcomes have not been yet as-sessed in a real-world asthma patient population. The primary objective is to describe patient characteristics and therapy path-ways for patients with a diagnosis of moderate to severe asthma who are treated with Trimbow® in real world practice. Secondary objectives include: * To assess asthma control (ACT) * To assess quality of life (Mini-AQLQ) * To assess treatment adherence (TAI) * To analyse parameters of lung function * To analyse parameters of small airways disease (FEF 25-75, RV/TLC) * To analyse parameters of asthma-related airway inflammation (FeNO) * To analyse parameters of persistent airways limitation (reversibility testing FEV1/FVC) * To analyse the incidence and the severity of asthma exacerbations * To analyse the use of rescue medication * To analyse the use of systemic corticosteroids * To assess healthcare resource utilisation * To assess treatment satisfaction with Trimbow® * To assess tolerability of Trimbow® This is a non-interventional, longitudinal, international, multicentre study with prospective data collection. At baseline, the patient's medical history with spe-cial focus on asthma will be collected. The study baseline visit is at the time point of start of treatment with Trimbow®. Trimbow® treatment may have started up to a maximum of 4 weeks prior to inclusion of the patient into this NIS. The planned observational period per patient should be at least 52 weeks (ob-servational period \[OP\] I of the study) and can be extended to up to 3 years (OP II of the study). During the observational period, data may be collected approximately every 3 months during the first year (OP I of the study) and thereafter every 6 months (OP II of the study). The present observational plan does not stipulate any study-related procedures or defined time points; only data that are available within the current clinical routine will be collected as documented in the patients' files.
