Completed

• Conditions: Asthma
• Interventions: Other: Non-interventional

Brief Summary

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.
