A Study to Assess Stroke Risk Among Users of Typical Versus Atypical Antipsychotics Stratified by Broad Age Group

June 20, 2025 updated by: Janssen Research & Development, LLC

Stroke Risk Among Users of Typical vs. Atypical Antipsychotics Stratified by Broad Age Group, a Post-authorization Safety Study

The purpose of this study is to extend the recent Food and Drug Administration (FDA) Sentinel tabulations regarding stroke risk among new users of typical and atypical antipsychotics to participants who were aged 18-64 years and did not have dementia to participants aged 65 years and older regardless of dementia status.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Sampling Method

Probability Sample

The study population is the participants in (any of) the target or comparator cohorts. Each target and comparator cohort will be drawn from the appropriate database: IBM MarketScan Commercial Database (CCAE) if the participants are aged 18-64 years and IBM MarketScan Medicare Supplemental Database (MDCR) if participants are aged greater than or equal to (>=) 65 years.

Inclusion Criteria:

For entry event of an initial drug exposure:

  • First exposure to the particular drug(s) in the past 183 days (index date)
  • Had at least 183 days of continuous observation time prior to index
  • Exactly 0 condition occurrences of 'Cancer' any time in the 183 days before or on the index date

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Stroke as a Principal Inpatient Diagnosis
Time Frame: Up to 16 years (from 01-January-2002 through 31-December-2017)
Number of participants with stroke in each target cohort versus comparator cohort (aged 65 years and older) per person years at risk will be reported. It is defined defined by the presence of the relevant ICD codes (ICD-9 or ICD-10 according to date) in the inpatient setting as the primary diagnoses.
Up to 16 years (from 01-January-2002 through 31-December-2017)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants at Stroke Risk when Compared Among New Users of Typical Antipsychotics/Haloperidol versus Atypical Antipsychotics
Time Frame: Up to 16 years (from 01-January-2002 through 31-December-2017)
The number of participants with the risk of stroke among participants exposed to typical antipsychotics versus atypical antipsychotics will be reported.
