A Multicentre, Prospective, Non-interventional Trial Monitoring Therapy Pathways of Asthma Patients Treated With an Extrafine ICS/LABA/LAMA Single-inhaler Triple Therapy in a Real-world Setting and Characterizing the Effects on Health-related Out-comes

TriMaximize, a non-interventional trial aims to collect prospective, longitudinal data from asthma patients under routine care, for whom their treating physician has decided to prescribe Trimbow® (beclometasone/formoterol/glycopyrronium).

Detailed Description

TriMaximize, a non-interventional trial aims to collect prospective, longitudinal data from asthma patients under routine care, for whom their treating physician has decided to prescribe Trimbow® (beclometasone/formoterol/glycopyrronium).

Trimbow is a fixed triple therapy containing a long-acting muscarinic antagonist (LAMA, glycopyrronium), a long-acting beta-adrenergic agonist (LABA, formoterol) and an inhaled corticosteroid (ICS, beclometasone).

Asthma patients often need to use multiple inhalers as part of their therapy, which require different inhalation techniques. It has been shown that the use of several inhalers of different mode of action, design and dosage requirements may have a detrimental effect on patient adherence and subsequent treatment outcomes.

In this prospective, non-interventional trial, the investigators aim to evaluate aspects of adherence to Trimbow, a single-inhaler triple therapy (SITT) as a maintenance treatment of asthma, to gather knowledge from routine care on whether appropriate step-up to SITT leads to greater adherence and better health outcomes.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients will only be included in the Non-Interventional Trial if Trimbow® has been prescribed in line with its current marketing authorisation and the guidance specified in the summary of product characteristics (SmPC).

Physicians are urged to offer enrolment to all of their eligible patients consecutively as they present for their routine visit, and not select patients from their patient database.

Eligible patients may only be included in the NIT after providing written (witnessed, where required by law or regulation), IEC-approved informed consent.

Description

Inclusion Criteria:

  1. Patients ≥ 18 years of age,
  2. Patients with confirmed leading diagnosis of asthma with or without concomitant COPD,
  3. Physician decision to start fixed triple therapy with ICS/LABA/LAMA (Trimbow MS or HS) according to its current authorised indication. The treatment decision must be made independently from participation in this NIS,
  4. Patients willing and able to sign an informed consent for use of their pseudonymised clinical data within the present non-interventional study.

Exclusion Criteria:

1) Participation in an interventional clinical trial within 30 days prior to enrolment into the present non-interventional study or planned enrolment in an interventional clinical trial during the observational period.

  • Time Perspectives: Prospective

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Asthma patients
Trimbow pMDI prescribed for maintenance treatment of adult asthma as per the licensed indication.
As this is a non-interventional trial, only data obtained within the current routine management of asthma at outpatient respiratory centres or GP centres will be documented.
