Brief Summary
The mainstay of asthma treatment are ICSs, mostly combined with LABA. In the past decade LAMA had been accepted as an add-on treatment for patients at GINA steps 4 and 5. Recently, RCTs proved the efficacy and safety of fixed triple combinations of moderate and high dose of ICS and LABA, LAMA in a very selected asthmatic population, resulting in the market authorisation of these products. However, there is a lack of evidence on the real-world effectiveness of these therapies, especially with regards to improvement in symptom scores and adherence.

Eligibility Criteria
Asthma patients treated at GINA step 5, uncontrolled/ partially controlled with ICS+LABA, containing high dose ICS.
You may qualify if:
- Patients ≥ 18 years of age in ambulatory care
- Uncontrolled asthma according to the physician's clinical assessment despite the use of:
- LABA and high dose ICS or
- LABA and high-dose ICS + LAMA multi-inhaler triple therapy for a minimum of three months.
- Patients who are eligible for the use of Trimbow 172/5/9 μg pMDI according to the SmPC :
- at least on exacerbation, requiring systemic (oral or intravenous) corticosteroids in the previous 12 months
- uncontrolled asthma (ACT≤15) or partially controlled asthma (15\<ACT\<20)
- FEV1\<80% at baseline
- Patient provided written, informed consent to study participation
You may not qualify if:
- Participation in any clinical trial within 30 days prior to enrolment
- Patients hospitalized due to an exacerbation of their asthma within the last 4 weeks prior to enrolment
- Another respiratory condition, apart from asthma or COPD, that may interfere with the effectiveness of the treatment studied AND/OR another important clinical situation that may interfere with patient's compliance with the treatment.
- Continuous use of oral (\>5 mg prednisolone/day OR \>4 mg methylprednisolone/day) OR intravenous corticosteroids
- Use of continuous oxygen therapy
- Any malignant disease in the last 5 years
- Tuberculosis (active or anamnestic)
