EU PAS Register NumberEUPAS12624
Official titleAn Active Safety Surveillance Program To Monitor Selected Events In Patients With Long-Term Voriconazole Use
Study title acronym
Study typeObservational study
Brief description of the studyThis is an observational cohort study examining the safety profile of Voriconazole in adults and pediatric patients, particularly those with long-term Voriconazole use (≥180 days of treatment). The study will utilize data from Swedish National Registers including the Swedish Prescribed Drug Register (SPDR), the Swedish Cancer Register (SCR), the National Patient Register (NPR), the Causes of Death Register (CDR), and the Registers of Statistics Sweden.

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 estimate the incidence rate of hepatic disorders, phototoxicity, SCC of the skin, visual disorders and periostitis among adult and paediatric patients receiving voriconazole, particularly with long-term use.
Are there primary outcomes?Yes
The primary study outcomes are hepatic disorders, phototoxicity, SCC of the skin, periostitis and visual disorders.
Are there secondary outcomes?Yes
Secondary outcomes include gastrointestinal disorders, nausea, vomiting, abdominal pain, abdominal discomfort, diarrhea, dyspepsia, flatulence, non-infective gastroenteritis, and 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
Patients will be followed from the index date (date of first filled voriconazole) to whichever of the following occurs first: death, emigration or 31 December 2019 (at which time all surviving patients will be censored).
15. Data analysis plan
Please provide a brief summary of the analysis method
Descriptive statistics will be performed to describe patient demographic and clinical characteristics.Demographic characteristics include age, sex, geographic region, county of birth, and occupation.Clinical characteristics include co-morbid/underlying conditions, use of voriconazole for approved or non-approved indications, and concomitant medications.Main outcomes (safety events) will be analyzed using a piecewise exponential model that allows separate estimation of the hazard within voriconazole treatment intervals (≤3 months, >3 to ≤6 months, >6 to ≤9 months, >9 to ≤12 months, and > 12 month).The following results will be presented by safety event:
• Incidence rates and cumulative incidence rates with corresponding 95% CI,
• Number of new events reported during follow-up,
• Cumulative person-time at risk, and
• Sub-group analyses of incidence rates across various demographic and baseline characteristics(i.e., age group, co-morbid/underlying conditions)when enough data exist
