1. Study identification
EU PAS Register NumberEUPAS27402
Official titleAssessment of The High risk and unmEt Need in patients with coronary artery disease and type 2 diabetes in France
Study title acronymATHENA-F
Study typeOther: Historical cohort study using the SNDS, the French nationwide claims database
Brief description of the studyAstraZeneca is working on an indication extension of ticagrelor for the prevention of cardiovascular (CV) death, myocardial infarction (MI) or stroke in patients with coronary arterial disease (CAD), but without medical history of previous MI or stroke at high risk of atherothrombotic events due to type II diabetes mellitus (T2DM). The ATHENA-F study purpose is to assess the prevalence and burden of CAD-T2DM without prior MI or stroke in France, as well as of the population with inclusion and exclusion criteria of the THEMIS randomized controlled trial (THEMIS-like population), using the French nationwide claims database (SNDS). The first study population will include all T2DM patients identified in 2013-2014 with CAD but without MI or stroke history, and affiliated to the general scheme from 2008 to 2016 (data extraction period). Each patient will be followed 2 years or until death and will have 5-year history in the database. THEMIS-like population will include patients of this first population aged ≥50 years at index, without history of intracranial bleeding, renal failure requiring dialysis, cirrhosis of liver or liver cancer, gastro-intestinal bleeding (within 6 months), antiplatelet agent or anticoagulant treatment within 2 months around index date. For prevalent patients (both T2DM and CAD), index date will be 01/01/2013; for incident patients the first date of the second diagnosis between T2DM or CAD. The number of CAD-T2DM patients is estimated to 550,000 patients in the SNDS, and the prevalence of the two study populations will be assessed on 01/01/2013 and 31/12/2014. The CV events (stroke, MI, CV death, all-cause death, heart failure, bleeding, and composite CV events of MI, stroke, CV death) during the study period will be described in terms of crude incidence rate (Normal approximation), cumulative incidence rate (Kaplan-Meier estimator or Cumulative Incidence Function), and risk factors of the composite CV events (Cox proportional hazards model).

12. Main objective(s)
What is the main objective of the study?
The main objective is to estimate the prevalence of CAD-T2DM without prior MI or stroke in France, as well as of the population with inclusion and exclusion criteria of the THEMIS randomized controlled trial (THEMIS-like population).
Are there primary outcomes?Yes
MI, ischemic or unknown stroke, CV death, composite CV events (MI, stroke, CV death), all-cause death, heart failure, major organ specific bleeding as intracranial haemorrhage, other critical organ or site bleeding (intraspinal, intraocular, retroperitoneal, intraarticular or pericardial, or intramuscular), other bleeding (GI, urogenital and other bleeding) with transfusion, fatal bleeding.
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 study follow-up period will start on the study index date and will end two years later, or until date of death. Index date will be 01/01/2013 for prevalent patients (both T2DM and CAD diagnoses) and for incident patients the first date of T2DM diagnosis for CAD prevalent patients or the first date of CAD diagnosis for T2DM prevalent patients.
15. Data analysis plan
Please provide a brief summary of the analysis method
Following analyses will be performed for CAD-T2DM without MI or stroke population and THEMIS-like population:
- Description of patients (Flow-Chart, demographic, clinical and therapeutic characteristics at inclusion and during the follow-up)
- Description of healthcare resources use and costs during the 2-year follow-up period according to the collective and national health insurance perspectives
- Prevalence estimate of each population on 01/01/2013 and 31/12/2014 among French population, overall and according to age and gender
- Cumulative incidence estimate of outcomes (stroke, MI, CV death, all-cause death, heart failure, bleeding, composite CV events of MI, stroke, CV death) using Kaplan-Meier estimator and Cumulative Incidence Function to take into account death as a competing risk, overall and according to 3 age-classes (<65, 65-75, >75)
- Predictors estimate of the composite CV events using a multivariable Cox proportional hazards regression model with a stepwise method
