1. Study identification
EU PAS Register NumberEUPAS2388
Official titleCalcium channel blocker treatments and cancer risk. A methodological protocol to compare the results between databases, across designs: Evaluation of the impact of design/database/population differences on the outcome of the studied association
Study title acronym
Study typeObservational study
Brief description of the studyThe studies described in this protocol are all performed within the framework of PROTECT (Pharmacoepidemiological Research on Outcomes of Therapeutics by a European ConsorTium) Work Package 2 and Working Group 1. The primary aim of these studies is to develop, test and disseminate methodological standards for the design, conduct and analysis of Pharmacoepidemiological (PE) studies applicable to different safety issues and using different data sources. To achieve this, results from PE studies on 5 key Drug / adverse events (D-AEs) pairs performed in different databases will be evaluated. The Use of calcium channel blockers associated with the risk of cancer is one of the key D-Ae pair of interest. Therefore, emphasis will be on the methodological aspects of the studies in this protocol and not on the clinical consequences of studying the association under investigation.

Primary scope : Analysis of discrepancies in results between different databases
12. Main objective(s)
What is the main objective of the study?
To assess the association between the use of calcium channel blockers and the risk of cancer with different study designs across different primary care databases and to compare the results between databases, across designs to evaluate the impact of design/database/population differences on the outcome of the studied association.
Are there primary outcomes?No
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cohort study
Case-crossover
Descriptive study = description of exposure and/or outcome in the whole database during a defined period of time
14. Follow-up of patients
Will patients be followed up?Not applicable/no follow-up
15. Data analysis plan
Please provide a brief summary of the analysis method
Preliminary analyses will use non-parametric univariate and bivariate analyses
Cox proportional hazard models with time-dependent covariates adjusted on confounders ill be used to calculate the association between CCB exposure and risk of cancer. RR and 95 % CI will be established.
CCB first-time and non-users between 01/01/1996 and 31/12/2009 will be followed from entry to the study until the earliest of: diagnosis date of study outcome (cancer), date of disenrollment from database, reaching 80 years of age, date of death, or end of study period
Three models will be performed
One model will be with at least 1 prescription
One model with pooled data with cumulated exposure
Analysis based on the main treatment groups
Propensity score will also be computed for the previous analyses
