Triple Therapy Convenience by the Use of One or Multiple Inhalers and Digital Support in Chronic Obstructive Pulmonary Disease

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.

Treatment and study plan

single-inhaler triple therapy (Trimbow)

Drug

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

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

Device

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

multi-inhaler triple therapy (Qvar + Bevespi)

Drug

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

Primary outcomes

  1. Adherence to ICS therapy

    Time frame: 12 months

    average 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 outcomes

  1. TAI questionnaire score

    Time frame: 12 months

    questionnaire that identifies non-adherence and gives insight in the barriers related to the use of inhalers in asthma and COPD

  2. CCQ questionnaire

    Time frame: 12 months

    measures health status and can be used to assess health-related quality of life

  3. VAS score

    Time frame: 12 months

    a non-specific scale to score an outcome from 0 (not satisfied at all) to 10 (extremely satisfied)

  4. PIH-NL

    Time frame: 12 months

    12-item scale to measure self-management behaviour and knowledge of patients with chronic diseases as COPD

  5. WPAI

    Time frame: 12 months

    questionnaire to measure impairments in work and activities

  6. EQ-5D-5L

    Time frame: 12 months

    questionnaire to assess the health-status

  7. HLS-EU-Q16

    Time frame: 12 months

    assessment of patients' health literacy

  8. Number exacerbations

    Time frame: 12 months

    A 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

  9. SABA use

    Time frame: 12 months

    Use of espace medication

Other outcomes

  1. Concentration of beclomethasone and formoterol in hair

    Time frame: 2-3 months

    In a subgroup of patients, beclomethasone and formoterol concentration in their hair will be measured
