1. Study identification
EU PAS Register NumberEUPAS9949
Official titlePost-discharge Clinical and Economic Outcomes Among Patients with ACS Managed with PCI and treated with Prasugrel versus Ticagrelor
Study title acronymH7T-MC-B023
Study typeObservational study
Brief description of the studyRetrospective cohort study using the Prometix Lx claims database to compare clinical and economic outcomes and treatment patterns among patients treated with prasugrel and those treated with ticagrelor. The primary study population will be patients with ACS managed with PCI who have no prior TIA or stroke (that is, indicated population for treatment with prasugrel). The primary study objective is to compare
NACE up to one year post-discharge from an index hospitalisation. The main study hypothesis will be to show that prasugrel is associated with non-inferior outcomes at 1 year compared to ticagrelor. Secondary
endpoints include clinical and economic outcomes and treatment patterns through 30 days, 6 months, and 1 year post index hospitalization discharge. Data will be assessed before and after adjustment for baseline risk differences via propensity score matching. The overall ACS-PCI population, as well as a subgroup of the primary population aged <75 years or >75 years with diabetes or prior MI, will be assessed.

Primary scope : Effectiveness evaluation
12. Main objective(s)
What is the main objective of the study?
The primary objective is to compare net adverse clinical events (NACE) up to 1 year post-discharge from an index ACS-PCI hospitalisation in patients treated with prasugrel versus ticagrelor. The main hypothesis is that, after adjustment for baseline differences, outcomes associated with prasugrel will be non-inferior to those with ticagrelor through 1 year for ACS-PCI patients in regards to NACE.
Are there primary outcomes?Yes
Net adverse clinical events (NACE) up to one year post-discharge from an index hospitalisation.
Are there secondary outcomes?Yes
Resource utilisation (medical and pharmacy utilisation) and other clinical outcomes (NACE components including bleeding rehospitalisations); healthcare charges; and treatment patterns (including adherence and persistence) at 30 days, 6 months, and one year post-discharge from the index hospitalisation.
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
Duration of follow-up: Up to 1 year
15. Data analysis plan
Please provide a brief summary of the analysis method
Baseline and outcomes data will be analysed before and after propensity matching. Unmatched cohorts will be compared with an appropriate 2-tailed statistic for continuous or categorical variables. Treatment groups will be matched based on baseline demographic, clinical, procedural, and payer characteristics. A one-sided test will then be computed to see if the clinical event rate difference between treatment groups is significantly <1.2 (20% non-inferiority margin). Cox regression will be used to compare clinical outcomes, with patients censored at the end of the index treatment exposure time (that is, 7 days after discontinuation or switching of the index medication). Per patient per month economic measures and incidence rates will be assessed to account for the variable follow-up. Economic outcomes and treatment patterns will be analysed after matching using descriptive statistics and appropriate regression models (for example, generalized linear model and logistic regression).
