EU PAS Register NumberEUPAS12839
Official titleLinaclotide Utilisation Study in Selected European Populations
Study title acronym
Study typeObservational study
Brief description of the studyThis study plans to describe the characteristics of patients newly prescribed linaclotide, especially in certain population subgroups for which the use of linaclotide was not sufficiently documented in the clinical programme (including the elderly, males, pregnant or breast-feeding women, and patients with specific comorbidities or taking other medications), and in groups with potential off-label use and patients with potential for abuse/excessive use. Linaclotide treatment patterns will be also described.

11. Scope of the study
What is the scope of the study?
Drug utilisation study
Primary scope : Drug utilisation study
12. Main objective(s)
What is the main objective of the study?
To describe linaclotide utilisation among patients from three selected European countries: UK, Spain, and Sweden.
Are there primary outcomes?Yes
Linaclotide treatment discontinuation and linaclotide treatment switching.
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cohort study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
The follow-up period for each study subject will be the time from the index date to the earliest of the following dates: end of the study period for follow-up, disenrollment from the database (date of transfer out of the practice), date of last data collection, death, or 1.5 times the number of days of linaclotide supply after the expiry of the last linaclotide prescription during the study period
15. Data analysis plan
Please provide a brief summary of the analysis method
Baseline analyses will be conducted to characterise linaclotide users, and socio-demographic and clinical variables will be described for all users and for those subgroups of patients who were not sufficiently documented in the clinical development programme. Linaclotide treatment patterns will be described from index date to end of study period for linaclotide utilisation. Kaplan-Meier estimates will be used to describe time to discontinuation in the prescription or dispensation of linaclotide; and to describe switching from linaclotide to another drug used in IBS-C.
To better assess differences in time to event by the alleged reason for linaclotide prescription (IBS-C or other condition), Cox regression analysis will be employed if the proportional hazards assumption holds; if not, more complex models will be proposed, including predictor variable interactions with time.
