Brief summary

TRICOLON is an investigator initiated, prospective, interventional, open-label, randomized, real-world, multi-centre, 3-arms study in the Netherlands. The primary objective is to investigate in COPD patients if single-inhaler triple therapy (SITT) is superior to multi-inhaler triple therapy (MITT) in terms of adherence to inhaled corticosteroids (ICS) therapy and to investigate if SITT with e-health support is superior to MITT and SITT without e-health support.

Interventions

DRUGsingle-inhaler triple therapy (Trimbow)

Patients in the intervention group will receive the triple therapy in one inhaler in stead of multiple inhalers. The actual medication is the same.

DEVICEE-health application: Curavista app & FindAir e-device

Patients in intervention group 2 will receive Trimbow and will use the health app of Curavista and the smart-inhaler of FindAir

DRUGmulti-inhaler triple therapy (Qvar + Bevespi)

Patients in the intervention group will receive the triple therapy in multiple inhalers. The actual medication is the same.

Design outcomes

Primary

MeasureTime frameDescription
Adherence to ICS therapy12 monthsaverage adherence to ICS therapy (expressed as a percentage, measured as the number of actuations registered by the e-device divided by the total number of prescribed doses) over 12 months of treatment

Secondary

MeasureTime frameDescription
TAI questionnaire score12 monthsquestionnaire that identifies non-adherence and gives insight in the barriers related to the use of inhalers in asthma and COPD
CCQ questionnaire12 monthsmeasures health status and can be used to assess health-related quality of life
VAS score12 monthsa non-specific scale to score an outcome from 0 (not satisfied at all) to 10 (extremely satisfied)
PIH-NL12 months12-item scale to measure self-management behaviour and knowledge of patients with chronic diseases as COPD
EQ-5D-5L12 monthsquestionnaire to assess the health-status
HLS-EU-Q1612 monthsassessment of patients' health literacy
Number exacerbations12 monthsA moderate exacerbation is defined as sustained worsening of the patient's condition, from a stable state and beyond day-to-day variation, that is acute in onset and warrants additional treatment (systemic corticosteroids and/or antibiotics). An exacerbation is defined as severe if hospitalization or emergency department visit is necessary
SABA use12 monthsUse of espace medication
WPAI12 monthsquestionnaire to measure impairments in work and activities

Other

MeasureTime frameDescription
Concentration of beclomethasone and formoterol in hair2-3 monthsIn a subgroup of patients, beclomethasone and formoterol concentration in their hair will be measured
