EU PAS Register NumberEUPAS16088
Official titlePost-authorization Safety Study Evaluation of Neoplasm Events in Users of Mirabegron and Other Treatments for Overactive Bladder : Core Common Protocol
Study title acronym
Study typeObservational study
Brief description of the studyMirabegron is a first in class therapeutic agent, with a mechanism of action distinct from that of antimuscarinic agents indicated for the treatment of overactive bladder (OAB). This post authorization safety study (PASS, or post marketing requirement (PMR) in the US) is designed to generate additional evidence to help evaluate the results observed in the clinical trials. To implement the program, we selected data sources from 5 research centers. The investigators are from RTI Health Solutions, Optum, University of Southern Denmark, Centre for Pharmacoepidemiology at Karolinska Institute, and Comprehensive Health Insights.
The study population will include patients observed in each of the 5 databases, providing a wide array of patient characteristics, drug utilization and medical practice patterns, which will enhance the generalizability of the study findings to the population of mirabegron users in real world practice, beyond clinical trials.
This will be a cohort study comparing the incidence of commonly occurring malignant neoplasms among new users of mirabegron and new users of any comparator antimuscarinic medication (as a group) used in the treatment of OAB. To provide a sufficiently large patient population within which to evaluate the safety of mirabegron, the study will be conducted within multiple databases. Each of these populations will be studied according to the same Core protocol, although operational details will vary across sites due to the specifics of the data environments. In addition to data source-specific analyses, estimates obtained from all data sources will be analyzed using a meta-analysis approach.
Overall, the study period includes October 2012 (first observed use of mirabegron in US data) through June 2019 (submission of final study report).

Risk assessment
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
Estimate the incidence of sex-specific composite cancer endpoint among users of mirabegron relative to antimuscarinic medication, overall and restricted to patients 65+ years. Estimate the incidence of 10 individual sex-specific cancers among users of mirabegron relative to antimuscarinic medication. Examine protopathic bias by comparing incidence in post-treatment initiation intervals.
Are there primary outcomes?Yes
Composite cancer endpoints: lung & bronchus, colon & rectum, melanoma of skin, urinary bladder, non-Hodgkin lymphoma, kidney & renal pelvis, pancreas, prostate (males), breast (females), corpus uteri (females)
Are there secondary outcomes?Yes
10 individual cancers included in the composite, sex-specific.
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
Follow-up will start on the day after the index prescription and continue until the earliest of: end of the study period, last date of data with validated cancer outcomes within each of the data sources, disenrollment, occurrence of any cancer, dispensing of a non-tablet antimuscarinic.
15. Data analysis plan
Please provide a brief summary of the analysis method
Within each data source, patients’ baseline characteristics will be determined through analysis of data available up to and including the cohort entry date. All covariates at baseline will be evaluated based on all available information, except for the evaluation of health care utilization and concomitant medications which will only be based on the 12 months before cohort entry. Accounting for potential confounders will be performed by matching on a PS estimated from available covariates to balance cohorts with respect to those covariates. Cox proportional hazards regression models of the time from the day after cohort entry until the occurrence of an event or censoring will be built. Censoring occurs on the last day of cohort eligibility and events occur on the dates of diagnosis of events. Primary analysis results will be stratified into time periods before or after 1 year since index exposure. S
