1. Study identification
EU PAS Register NumberEUPAS10298
Official titlePregabalin abuse in France : a national cohort study
Study title acronym
Study typeObservational study
Brief description of the studyPregabalin is a psychoactive drug indicated in neuropathic pain, generalized anxiety disorder and partial epilepsy. It modifies neuronal activity, binding α2δ1 presynaptic voltage-dependent calcic channel receptor, which is responsible for its psychotropic action. Neuropsychiatric adverse drug reactions, such as euphoria, have been described.
Pregabalin abuse has been suggested in a few toxicological studies, pharmacovigilance studies, and small surveys among opioid users or treated by opiate maintenance drugs. Despite signals of abuse in some European countries, no data suggest a potential for pregabalin abuse in France, and no study has ever compare pregabalin abuse to other drug used in the same indication. Searching a possible pregabalin abuse seems all the more relevant as its consumption increases in France and in Europe. This study aims to investigate pregabalin abuse and its frequency in the French general population, in comparison with other drugs used in similar indications and to determine the factors associated with pregabalin abuse.

Additional information
All new users of pregabalin, gabapentin or duloxetine identified in the EGB will be included at the time of the first reimbursement, from 15th June 2006, date of the first reimbursement of pregabalin in the EGB, to the end of 2012.

11. Scope of the study
What is the scope of the study?
Risk assessment
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
The main objective of this study will be to assess pregabalin abuse and its frequency in the French general population, in comparison to other drugs with similar indications (gabapentin and duloxetine), in a pharmacoepidemiological, observational, French national retrospective cohort study.
The secondary objective is to determine the factors associated with abuse of each drug.
Are there primary outcomes?Yes
Occurrence of drug abuse along time will be the main outcome (abuse of pregabalin in pregabalin group, etc.). The abuse will be defined by the exceeding of maximum daily dose recommended. For every 3 drugs studies, this maximum corresponds to 2 daily DDD
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 cohort inclusion will start the 15th June 2006, date of the first reimbursement of pregabalin in the EGB database, and end the 31th December 2012. Follow-up will be performed until the last data available in 2015 (i.e. December 2014).
15. Data analysis plan
Please provide a brief summary of the analysis method
Outcome will be abuse of the cohort study drug, defined as a daily abuse above the maximum recommended dose. Abuse will be investigated through a Kaplan-Meier survival model. Factors associated with abuse will be investigated through a Cox proportional hazard regression model with time dependent covariates.
