About this study

Official title: Atomoxetine and Cerebrovascular Outcomes in Adults

Using a proprietary insurance health claims database, Eli Lilly and Company has contracted with an external party to conduct a retrospective cohort study of health claims for the time period from 1 January 2003 through 31 December 2006 (with follow-up of patients through 30 June 2007). This study will evaluate the potential association between atomoxetine and cerebrovascular events. In this study, the incidence of selected cerebrovascular outcomes as represented in health claims data among adult patients who initiate therapy with atomoxetine will be estimated. In particular the study will focus on cerebrovascular accident (CVA) and transient ischemic attack (TIA) as the outcomes of interest. The incidence for each outcome among atomoxetine initiators will then be compared to the incidence in a cohort of similar patients who initiate stimulant treatment and an age and gender-matched general population cohort. The atomoxetine and stimulant-initiating cohorts will be matched on a broad variety of variables, including age, gender, diagnoses, medication use, and healthcare utilization through the use of propensity score matching in order to minimize the influence of confounding by indication. The analysis will include the cohorts (atomoxetine and stimulant initiators) from a previous completed study with increased follow-up time (1 January 2003 through 30 June 2007) and accrue new atomoxetine and stimulant ADHD medication initiators over a 2 year period, so that the study will represent initiators between January 1, 2003 and December 31, 2006 with follow-up through June 30, 2007.

Study groups in NCT00634439
Study groupRoleWhat they receive
AAll patients 18 years or older who received a first dispensing of atomoxetine during the time period of the study (January 1, 2003 through December 31, 2006) and had at least 6 months of continuous enrollment prior to first dispensing are included in the study cohort. Patients are excluded for presence of pre-existing arrhythmia and heart failure during the baseline period. The study entry date for this cohort is the date of first atomoxetine dispensing.
Receives: Drug: atomoxetine
BAll patients 18 years or older who received a first dispensing of a stimulant medication (methylphenidate or mixed salts of amphetamine) during the time period of the study with no dispensing of the same drug in the prior 6 months and had at least 6 months of continuous enrollment prior to the first dispensing are identified. Patients are excluded for presence of pre-existing arrhythmia and heart failure during the baseline period. Patients who are matched to atomoxetine initiators using this propensity score method are retained and followed as one comparator cohort. The study entry date is the date of the first dispensing of a comparator ADHD medication.
Receives: Drug: Stimulants
CPatients with at least 6 months of continuous enrollment in the database, and without a history of arrhythmia or heart failure during the baseline period are sampled and frequency matched on age and gender to the atomoxetine cohort in a 2:1 ratio. Study entry dates are assigned so as to be similar to the distribution of study entry dates in the atomoxetine cohort. Patients identified and matched as initiators of atomoxetine or stimulant ADHD medications are not eligible for inclusion in this cohort
Receives: Other: No intervention (general population)

Questions about this trial

What is this clinical trial studying?

An observational study of Cerebrovascular Accident and Transient Ischemic Attack, run by Eli Lilly and Company at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Sep 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cerebrovascular Accident (CVA) (time frame: January 2003 - June 2007). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2009.
