The CATALINA Study
- Conditions
- Chronic Obstructive Pulmonary Disease Exacerbation
- Registration Number
- NCT05008081
- Lead Sponsor
- Wim Janssens
- Brief Summary
The CATALINA study is a prospective cohort study embedded within CICERO (Collaboration In COPD ExaceRbatiOns, a European Respiratory Society supported Clinical Research Collaboration), designed to collect standardised, longitudinal clinical data and biological samples in 20 centres across Europe and beyond.
- Detailed Description
The initial objective is to recruit 1000 patients hospitalised for an acute COPD exacerbation by the end of CICERO's first lifecycle (3 years), from whom 1 year follow-up data and biological samples will be collected. By doing so, CICERO aims to develop a comprehensive European COPD patient data- and biobank phenotyped in relation to the exacerbation, to support the development of future EU-wide clinical intervention trials in COPD for specific patient subgroups, as well as new prognostication tools for COPD exacerbations.
The clinical data and biological samples will be obtained during 6 scheduled study visits, during the hospitalization period of the index acute exacerbation as well as the outpatient setting after hospital discharge; and 3 additional unscheduled study visits should the patient be readmitted for respiratory reasons during study participation (i.e. first readmission only).
* 3 study visits will be scheduled during the hospitalization period of the index acute exacerbation:
* visit 1: within 48h of hospital admission, study inclusion (Day 1)
* visit 2: at 72h after study inclusion (Day 3)
* visit 3: at hospital discharge, at investigator's discretion (Day X)
* 3 study visits will be scheduled during the outpatient setting:
* visit 4: at 3 months after study inclusion (Day 90)
* visit 5: at 6 months after study inclusion (Day 180)
* visit 6: at 12 months after study inclusion (Day 365)
* The first hospital readmission for respiratory reasons during the patient's study participation will undergo the same testing schedule as mandated during the hospitalization period of the index event:
* unscheduled visit 1: within 48h of first hospital readmission
* unscheduled visit 2: within 72h of first hospital readmission
* unscheduled visit 3: at hospital discharge for first hospital readmission
Resulting from CICERO's future lifecycles will be the continued expansion of the data- and bio-bank, both in cohort size and duration of follow-up.
