Study summary

The CHRONICLES study will investigate the change in clinical and patient reported outcomes after six-months of treatment with Budenoside/Glycopyrronium/Formoterol [BGF] in a real-world setting.

Read the detailed description

This is a prospective, open label, non-interventional, single network of clinical practice centers study that will be conducted in routine clinical care in the pulmonary/ primary care practitioner (PCP) care setting in Ontario, Canada. Eligible patients will be enrolled into the study only following the treating physician's decision and patient agreement to initiate treatment with BGF. Patients will be observed for up to 6 months post-treatment initiation with BGF.

Study population

Patients with moderate to severe COPD who are eligible for BGF therapy may be enrolled by physicians in primary care setting. The decision to start treatment with BGF must be made by the treating physician according to the subjects' medical need and a positive benefit/risk balance. The decision to prescribe BGF must be independent of enrolment into the study, is determined by the treating physician and should be taken according to the standard of current best medical practice and national guidelines.

Inclusion criteria

  • Physician diagnosis of COPD
  • COPD patients in the Best Care Network who have a CAT score >=10
  • Age >=35 at time of enrolment
  • Minimum 12-month recorded prior medical history for patients
  • Physician decision and patient agreement to initiate treatment with Breztri based on routine care (and in accordance with label and reimbursement criteria)
  • Ability to read English and to provide consent to inclusion in the study

Exclusion criteria

Exclusion Criteria:

  • Diagnosis of asthma
  • Dementia or other health issues related to memory
  • Inability to use inhalers
  • COPD due to documented α-1 antitrypsin deficiency
  • Previous treatment with triple fixed-dose combination therapy in 12 months prior to screening visit
  • Hospitalisation due to COPD exacerbation within the last 30 days prior to enrolment
  • Pregnancy or lactation period
  • Participation in an ongoing clinical interventional or observational trial for another COPD medication (or completed another trial within last 30 days of initiating BGF)
  • Patient self-reporting or a physician record with an active COVID-19 infection at time of enrolment or hospitalized due to COVID-19 infection in the last 60 days
  • Previous enrolment in this study

What researchers measure

Primary outcomes

  1. Mean change from baseline in the COPD Assessment Test (CAT) score

    To estimate the change in COPD health status in patients initiating BGF after 12 weeks

    Time frame: 12 weeks after treatment initiation

Secondary outcomes

  1. Demographic and clinical characteristics at baseline

    To describe the demographic and clinical characteristics of patients in the study

    Time frame: At baseline

  2. Change from baseline in CAT score after 24 weeks of treatment

    To estimate the change in COPD health status after 24 weeks from treatment initiation

    Time frame: 24 weeks from treatment initiation

  3. Change in patient quality of life as measured by EQ-5D-5L at 12 and 24 weeks post-treatment initiation

    To estimate the change in patient quality of life after 12 and 24 weeks of treatment initiation

    Time frame: 12 and 24 weeks after treatment initiation

  4. Change in measures of sleep quality using CASIS (COPD and Asthma Sleep Impact Scale) at weeks 12 and 24

    To estimate change in sleep quality following introduction of BGF

    Time frame: 12 and 24 weeks of treatment initiation

  5. Percent responders of the CAT [MID=2] after 12 weeks treatment compared to baseline

    To describe the Responder Rate based on the CAT after 12 weeks of initiating treatment with BGF

    Time frame: 12 weeks treatment compared to baseline

  6. The annualized rate of moderate and severe exacerbations that occurred within the previous year is collected at the baseline visit and the number of moderate and severe exacerbations occurring during the study is collected at the final visit

    To describe and compare the rate of moderate and severe exacerbations

    Time frame: Baseline (12 months prior to initiating BGF) and during the follow-up period (up to 6 months))
