Investigation of Fixed Triple Inhaled Combination in Asthmatic Patients, in a Real-life Setting

Study design Multicentre, national, non-interventional, prospective study evaluating the effectiveness of Trimbow 172/5/9 μg pMDI on symptom scores in 6 months after switch from previous LABA-high dose ICS containing treatment in asthmatics. Dosage regimen and administration Name of the product: Trimbow 172 micrograms/5 micrograms/9 micrograms pressurised inhalation, solution (henceforth abbreviated as Trimbow 172/5/9 μg pMDI). Each delivered dose (the dose leaving the mouthpiece) contains 172 μg of beclometasone dipropionate, 5 μg of formoterol fumarate dihydrate and 9 μg of glycopyrronium (as 11 μg glycopyrronium bromide). Each metered dose (the dose leaving the valve) contains 200 μg of beclometasone dipropionate, 6 μg of formoterol fumarate dihydrate and 10 μg of glycopyrronium (as 12.5 μg glycopyrronium bromide). The recommended dose is two inhalations twice daily. The maximum dose is two inhalations twice daily. 1. Aim of the study (research objective) Primary objective: The main objective is to assess the effectiveness of BDP/FF/G 172/5/9 μg fixed triple combination in a real-world setting, with regards to improvements in symptom scores (ACT). 2. Test sample and method, recruitment principle No patient recruitment will be performed. Eligible patients will be enrolled during the participating physicians' regular asthma patient management and patients' written informed consent. Patient inclusion will take place among patients having severe asthma and attending pulmonology outpatient clinics (the chosen study sites are attached as annexes to the study protocol), strictly at the time of the patients' visit. The planned number of patients is 800. 3. Structure of the study In accordance with the requirements of non-interventional studies, the assignment of patients to Trimbow 172/5/9 μg pMDI therapy should be made independently of the study, and patients should only be considered for inclusion in the study after a prior therapeutic decision has been made by a pulmonologist. Patient enrolment can take place after the patient has been fully informed about the purpose of the study and all of its details, and the patient has read and signed the patient information leaflet and patient consent form, including any questions they may have. Once this has taken place, the data that would have been generated anyway during the outpatient examination of the patient in accordance with daily practice can be recorded. This is considered the first visit of the study (Visit 1). During this visit, the patient's main demographic data, information on comorbidities and concomitant medications, previous and current asthma therapies, asthma specific assessment (including ACT), exacerbation history, post-dose lung function values (if spirometry data is available), laboratory results (if a laboratory test is performed during the visit or was performed recently), results of other medical examinations (e.g., chest X-ray) if performed regardless of the study, maintenance and reliever inhaled \& non-inhaled therapies (former and new) baseline quality of life based on the asthma quality of life (EQ-5D-5L) questionnaire, and adherence to therapy based on Test of Adherence to Inhalers® (TAI-12) questionnaire are recorded. Patients will then attend two additional visits 30 days and 6 months after enrolment as per routine clinical practice (Visits 2 and 3). During these visits, data will also be recorded, once again, according to routine clinical practice. Assessing the usage of rescue medications and patient adherence are also planned with the use of electronic health record system (EESZT)-verified prescription dispensations (optional for investigators). Visit 4 will be a long-term follow-up to assess the exploratory endpoint of exacerbations rates. If the patient's maintenance therapy changes during the study as decided by the treating pulmonologist, and the patient is no longer receiving Trimbow 172/5/9 μg pMDI, the patient will be automatically excluded from this NIS. The fact of the therapy modification and its exact date must be recorded on the "current medication" form in the eCRF (electronic Case Report Form) of the next visit. If the change in therapy is related to a suspected adverse reaction, it should be reported separately on the eCRF platform in accordance with section 9 of this protocol ('Collection, recording and reporting of medication safety data'). This NIS is open to all eligible patients according to the inclusion and exclusion criteria. Permitted concomitant treatments: allowed all medications according to local clinical practice (any non-inhalation therapy for asthma or other diseases) and reliever (short-acting bronchodilators) inhaled therapies for asthma. The data to be recorded will be detailed in the study data sheet that forms part of the protocol. The data is recorded in the eCRF (MrAgent - Medisol Development Ltd., see also at 10.1.) system, with consideration to the current professional and legal regulations. 4. Start and duration of the study The first patient enrolment will take place after receiving approval from the National Public Health Center (NPHC), based on a beneficial assessment of the Medical Research Council of Hungary. The study is planned to start on September 16, 2024. Accordingly, first patient first visit (FPFV) is also planned to take place in September, 2024. The launch of the participating centres is planned in two waves, in the autumn of 2024 and in the spring of 2025. Each centre will have 12 months to enrol patients. After the last visit of the last patient (LPLV), centres will have one month to collect all missing data / correct any data flagged as queries during monitoring. Thus, the LPLV will take place on Oct 31, 2026 (primary endpoint) and 30 April, 2027 (exploratory endpoint), respectively. The study is planned to be concluded on August 31, 2027. 5. Data to be recorded during the visits A total of 4 visits will be performed for the assessment of the primary and secondary endpoints during the study. The table below summarises the data collection to be carried out during the visits separately. The patient may be enrolled in the study and their data may only be recorded, if these data would also have been recorded in accordance with standard medical practice. * Visit 1: Time of enrolment - a normal visit, according to routine clinical practice. Informed consent and baseline patient characteristics will be collected. * Visit 2: 1 month after enrolment (± 2-3 workdays) * Visit 3: 6 months after enrolment (± 5-7 workdays) * Visit 4: 12 months after enrolment (± 10-15 days)
