1. Study identification
EU PAS Register NumberEUPAS34531
Official titleSuicide and suicidality after exposure to finasteride
Study title acronymSuicidality with finasteride
Study typeObservational study
Brief description of the studyFinasteride – indicated for benign prostatic hyperplasia (BPH) and male pattern hair loss (MPHL) - is known to cause psychiatric side effects. There are ongoing signals of persistence of psychiatric events after discontinuation of finasteride and of suicide/self-injury which remain under close monitoring. The principal objectives of this study are: (i) to assess the extent to which patients prescribed finasteride 5mg (BPH indication) are at increased risk of recorded suicide and suicide-related outcomes compared with patient prescribed alternative treatments for BPH; (ii) to assess if any association between finasteride 5mg exposure and recorded suicidality persists after cessation of therapy; and (iii) to describe the pattern of recorded events in patients prescribed finasteride 1mg (MPHL indication). This will be a cohort study with cohorts defined based on patients’ exposure to the medicines under investigation. The population eligible for the study will consist of male patients (finasteride is not indicated for use in females) registered with an IMRD-UK registered GP-practice for a duration of one-year or more. To avoid potential confounding relating to differing baseline risks a covariate adjusted analysis will be used. This will require the use of a minimum one-year lookback period prior to the start of follow-up to establish any baseline comorbidities. The primary analysis will be a new-user “inception” cohort of patients established through the one-year screening period to define incident use. Patients will be followed from the date of first prescription until an event or censored. The primary (composite) analysis will follow-up until first event and the secondary (component part / alternative composite) analysis will follow-up until first event of each type. Patients will be censored at the end of follow-up or when they switch to alternative therapy for BPH.

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?
To assess if use of finasteride is associated with increased risk of suicidality.
Are there primary outcomes?Yes
The primary outcome will be a composite consisting of the first occurrence of any of the following events: completed suicide; attempted suicide; and suicidal ideation.
Are there secondary outcomes?Yes
The secondary outcomes will be the component parts of the primary outcome, following up until the first event of each of the following: (i) completed suicide; (ii) completed or attempted suicide. In addition, all-cause deaths will be used as a sensitivity analysis because of the risk of misclassification of cause of death.
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
"Electronic" follow-up until end of coverage on database.
15. Data analysis plan
Please provide a brief summary of the analysis method
Multivariable survival modelling (most likely a Cox proportional hazards model) will be used to calculate adjusted Hazard Ratios associated with medication of interest use vs comparators, adjusting for potential confounders measured at baseline. Covariates will be included in the analysis by contributing to a propensity score for each patient and will be included in the model as inverse probability of treatment weights.
