The goal of this observational study is to determine if using the SiA® (Systematic Intervention Agent) system can improve inhaler technique and medication adherence in adults with asthma who are already using Trimbow pMDI inhalers. Furthermore, it will be addressed if the SiA® system can be used to discriminate between patients, where increased inflammatory markers are caused by incorrect inhaler technique/adherence to medication or patients that have ongoing inflammation requiring adjustment of therapy. Potentially those who might become candidate for biological treatments. The main questions it aims to answer are: * Can the SiA® system improve inhaler use and medication adherence in asthma patients? * Does improving inhaler technique and adherence lead to better asthma control and reduced airway inflammation (measured by FeNO levels)? Participants will: * Use the SiA® system, which includes a smart inhaler cap (RespiPRO™) and a mobile app * Continue their prescribed Trimbow pMDI treatment for asthma. * Have their asthma control, lung function, and FeNO levels monitored at specific points over 1 year (3 months and 12 months). The study does not have a comparison group and all results will be compared to baseline.
Background and Rationale Asthma is a chronic inflammatory disease of the airways that affects millions of individuals worldwide. Despite the availability of effective inhaled medications, poor adherence and incorrect inhaler technique remain major barriers to optimal asthma control. Studies show that up to 86.7% of asthma patients make at least one inhaler technique error, and 30-40% demonstrate poor adherence to their prescribed medication. These factors contribute to worsened symptoms, increased healthcare utilization, and reduced quality of life. The SiA® system, developed by Briota ApS, aims to address these challenges by integrating a smart inhaler cap (RespiPRO™) with a mobile application. This system provides real-time feedback on inhaler technique and adherence, allowing patients and healthcare providers to track progress and make necessary adjustments. This study seeks to determine whether using the SiA® system alongside a pressurized metered dose inhaler (pMDI) therapy can lead to measurable improvements in medication adherence, inhalation technique, and asthma control. Furthermore, it will be addressed if the SiA® system can be used to discriminate between patients, where increased inflammatory markers are caused by inadequate treatment caused by incorrect inhaler technique/adherence to medication or patients that have ongoing inflammation requiring adjustment of therapy. Potentially those who might become candidate for biological treatments. Study Design This is a prospective, single-arm observational study conducted at two hospitals in Denmark. It is designed to assess how the SiA® System impacts inhaler technique and medication adherence over a 12-month period. Key Features of the Study Design: * Observational (non-interventional): Participants will continue their standard asthma medication (Trimbow pMDI) but will use the SiA® system to monitor their inhaler technique and adherence. * Single-arm design: All participants will receive the SiA® System - there is no comparison group. * Real-world setting: The study aims to reflect how patients interact with the SiA® system in everyday life, outside of a controlled clinical trial environment. Study Setting: * Conducted at two specialized respiratory clinics in Denmark. * Participants will be recruited from routine asthma care visits. Data Collection Methods: Data will be collected through multiple sources: * Hospital medical records (to gather historical asthma data and prior exacerbation history). * Spirometry tests (to assess lung function). * FeNO tests (to measure airway inflammation). * SiA® System data (to track inhaler adherence and technique). * Patient-reported outcome measures (questionnaires on asthma symptoms and quality of life). Technology Used in the Study: * RespiPRO™ Smart Inhaler Cap: A device that attaches to Trimbow pMDI and records inhaler usage data. * SiA® Mobile App: Tracks daily inhaler use, provides feedback, and sends adherence reminders. Study Timeline: Total Study Duration: 22 months, with individual patient follow-up lasting 12 months (52 weeks). Patient Flow and Study Visits: 1. Screening and Baseline Visit (Week 0) - Study Enrolment * Patients will be identified during routine asthma care visits and screened for eligibility. * Informed consent will be obtained. * Baseline data collection will include: * Medical history * Asthma severity and medication use * Spirometry test (lung function) * FeNO test (airway inflammation) * ACT (Asthma Control Test) and mini-AQLQ (Asthma Quality of Life Questionnaire) * Patients will receive a brief training session on how to use the SiA® System. * A baseline inhaler technique video will be recorded using the SiA® Mobile App. 2. Interim Follow-up Visit (Week 12) - Progress Check * Patients will return for an in-person visit. * Repeat measurements: * FeNO test (to check inflammation levels). * Spirometry (lung function test). * ACT and mini-AQLQ (patient-reported outcomes). * Adherence data from the SiA® system will be reviewed. * Patients will complete a satisfaction survey about their experience with the SiA® system. 3. Final Study Visit (Week 52) - End of Study * Repeat FeNO, spirometry, ACT, and mini-AQLQ assessments. * The final inhaler technique video will be recorded and analyzed. * Patients will return or deactivate the RespiPRO™ Smart Inhaler Cap. * Final adherence and inhalation technique data will be collected from the SiA® Dashboard. Potential Impact of the Study This study aims to generate real-world evidence on how digital health interventions can improve asthma management. If successful, the SiA® System could: * Enhance asthma control by ensuring patients use their inhalers correctly. * Reduce unnecessary medication escalation, preventing overuse of corticosteroids. * Lower healthcare costs by reducing asthma-related hospital visits. * Empower patients with real-time feedback and better self-management tools. * Improve and optimize the way asthma patients become candidate for biological treatments

RECRUITINGTo evaluate the impact of the SiA® platform on the level of the type 2 inflammation biomarker FeNO
To assess the impact of the study on the type 2 biomarker FeNO with a change from baseline of at least 20% will be considered clinically relevant. FeNO values will be presented as ppb. FeNO levels of \< 25 ppb, 25 - 50 ppb, \> 50 ppb, are considered low, medium, and high respectively.
Time frame: Change from baseline in FeNO at week 12 and 52.
To assess the impact of the SiA® platform on adherence to SITT and inhaler technique measure using the RespiPRO add-on module
Change in inhaler adherence measured as percentage of days covered and inhaler technique scores based an assessments of inhalation video recordings an data collected from the SiA® platform using a scoring system of 1-5, where 5 = Optimal technique; 4 = Poor technique with one critical error; 3 = Poor technique with two critical errors; ≤2 = Poor technique with three or more critical errors. The RespiPRO™ cannot monitor step 1 and 2, thus are these by default set to 1, hence the minimum inhaler technique scores achievable from RespiPRO™ is 2.
Time frame: Change in pMDI inhaler technique score and medication adherence score at week 12 and 52 compared to baseline.
To evaluate the impact of the SiA® platform on asthma control using Asthma Control Test
Asthma control will be assesed using Asthma Control Test (ACT), which is a patient self-administred tool for identifying those with poorly controlled asthma. A maximum score of 25 points indicates complete asthma control. A score between 20 and 25 represents well controlled asthma, while a score of 19 or below represents not well controlled asthma, and a score less than 16 indicates very poorly controlled asthma.
Time frame: Change in ACT scores from baseline at weeks 12 and 52
To evaluate the impact of the SiA® platform on health-related quality of life
To assess the impact of the study on Health-related Quality of Life (HR QoL) using Asthma Quality of Life Questionnaire (mini-AQLQ). The mini-AQLQ has 15 questions in the same domains as the original AQLQ (symptoms, activities, emotions and environment).
Time frame: Change in mini-AQLQ scores from baseline at weeks 12 and 52
To evaluate the impact of the SiA® platform on lung function measured by spirometry
Change in lung function parameters (change in mean FEV1, FEV1 %-predicted, FEV1/FVC ratio, FEF25-75) from baseline at weeks 12 and 52
Time frame: From baseline and at week 12 and 52.
To evaluate the impact of the SiA® platform on shifts in FeNO category
Change in FeNO category (low, intermediate, high) defined as (\< 25 ppb, 25 - 50 ppb, \> 50 ppb, respectively.
Time frame: Change from baseline at week 12 and 52.
To evaluate the impact of the SiA® platform on annualized exacerbations rates
