Abstract

OBJECTIVE:

This meta-analysis examined suicide-related events in the acute phases of double-blind, placebo-controlled atomoxetine trials in pediatric and adult patients with attention-deficit/hyperactivity disorder (ADHD).

METHODS:

A total of 3883 pediatric and 3365 adult patients were included. Potential events were identified from the adverse events database using a text-string search. Mantel-Haenszel risk ratios (MHRR) were calculated for potential suicide-related events categorized according to United States Food and Drug Administration defined codes.

RESULTS:

In this data set, no completed suicides were reported in the pediatric or adult populations. One pediatric (attempted suicide) (and no adult patient events) was categorized as suicidal behavior in the atomoxetine group. The frequency of combined suicidal behavior or ideation with atomoxetine treatment was 0.37% in pediatric patients (vs. 0.07% with placebo) and 0.11% in adults (vs. 0.12% with placebo) and the risk compared with placebo was not statistically significant (MHRR=1.57; p=0.42 and MHRR=0.96; p=0.96, respectively). In pediatric patients, suicidal ideation only was reported more frequently compared with placebo (MHRR=1.63; p=0.41).

CONCLUSIONS:

Overall in this data set, no completed suicides and 1 pediatric patient suicidal behavior event were reported in atomoxetine-treated pediatric and adult patients. Suicidal ideation was uncommon among atomoxetine-treated pediatric and adult patients, although it was reported more frequently in atomoxetine-treated pediatric patients compared with placebo; the reporting rate difference was not statistically significant. The MHRR of suicidal ideation was consistent with a previous meta-analysis of similar design. There was no evidence of increased risk for suicidal behavior in atomoxetine-treated pediatric or adult patients.

CLINICAL TRIAL REGISTRATION INFORMATION:

http://www.clinicaltrials.gov . The data reported are from an analysis of 23 pediatric and 9 adult clinical trials completed between 1998 and 2011. Ten pediatric (Studies HFBD, HFBK, LYAC, LYAS, LYAT, LYAW, LYAX, LYBG, LYBI, and LYBP) and two adult trials (Studies LYAA and LYAO) were conducted before the requirement to post trials at initiation (ongoing as of July 1, 2005) and, therefore, do not have a registration number. The registration numbers for the 13 pediatric trials meeting this requirement are: NCT00191698 (LYBX), NCT00486122 (LYCC), NCT00386581 (LYCZ), NCT00485459 (S010), NCT00191542 (LY15), NCT00191295 (LYBC), NCT00191906 (LYCK), NCT00192023 (LYCY), NCT00191945 (LYDM), NCT00546910 (LYDV), NCT00406354 (LYDW), NCT00380692 (S017), and NCT00607919 (LYEB). For the seven adult trials, the registration numbers are: NCT00190931 (LYBV), NCT00190957 (LYBY), NCT00190736 (LYCU), NCT00190775 (LYCW), NCT00190879 (LYDQ), NCT00510276 (LYDZ), and NCT00962104 (LYEE).
