NCT06786767

Brief Summary

The mainstay of asthma treatment are ICSs, mostly and usually combined with LABA. In the past decade LAMA had been accepted as an add-on treatment for patients on GINA treatment 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 authorization 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 quality of life.

Outcome Measures

Primary Outcomes (2)

  • Asthma Control Test

    Change (improvement) of Asthma Control Test score, during the 6 months of treatment (Visit 3), compared to the score at baseline. A maximum score of 25 points indicates complete asthma control, while a score less than 16 indicates very poorly controlled asthma.

    6 months

  • Asthma Control Test - 2

    The percentage of patients achieving an improvement in Asthma Control Test score of 3 points (MCID, minimum clinically important difference) or more, after the 6-month treatment (Visit 3) compared to baseline. A maximum score of 25 points indicates complete asthma control, while a score less than 16 indicates very poorly controlled asthma.

Study Arms (1)

Asthmatic patients switched to Trimbow (BDP/FF/G 172/5/9 μg)

Asthmatic patients switched to BDP/FF/G 172/5/9 μg before study enrollment or at the day of enrollment due to uncontrolled asthma (a) patients who experienced one or more asthma exacerbation in the previous year and uncontrolled despite the use of b1) LABA and high dose ICS or b2) LABA and high-dose ICS + LAMA multi-inhaler triple therapy.

Drug: BDP/FF/G (Beclomethasone diprprionate, formoterol fumarate, glycopyrronium bromide) 172/5/9 μg

Interventions

As this is a non-interventional study, it is accordance with routing clinical practice. The assignment of patients to Trimbow 172/5/9 mcg should be made independently from the study.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patient inclusion will take place among patients having severe asthma at outpatient clinics in the selected and approved sites.

You may qualify if:

  • Patients ≥ 18 years of age in ambulatory care
  • Patients who are eligible for the use of Trimbow 172/5/9 μg pMDI according to the SmPC
  • patients who experienced one or more asthma exacerbation in the previous year AND
  • patients not adequately controlled according to the physician's clinical assessment despite the use of b1) LABA and high dose ICS OR b2) LABA and high-dose ICS + LAMA multi-inhaler triple therapy. FEV1\<80% at baseline. (spirometry performed at the visit 1 independently of the study or up to 30 days before the enrolment or within 3 days after Visit 1 is acceptable).

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.
  • Diagnosis of COPD.
  • Tuberculosis (active or anamnestic)
  • Actual or previous use of biologics for asthma treatment in the past 12 months
  • Hypersensitivity to the active substances or to any of the excipients listed in the SmPC
  • Pregnancy and lactation.
