3Overview
- Attention-deficit/hyperactivity disorder (ADHD)
is a recognized disorder of children and
adolescents - Untreated ADHD has serious consequences
- Methylphenidate products, including CONCERTA,
have proven efficacy in treating ADHD - We intend to review the safety data and the
adequacy of the labeling in the context of the
recognized benefits of CONCERTA

15Cardiovascular SafetyConclusions
- The low rates presented for cardiovascular events
continue to support the favorable benefit/risk
profile of CONCERTA in the treatment of ADHD - Current labeling recommends monitoring of blood
pressure in patients taking CONCERTA, especially
those with hypertension - A recent labeling change was undertaken to
address sudden death and preexisting structural
cardiac abnormalities

indications and warnings sections

29Understanding Suicide and Suicidality in the ADHD
Population
- Background prevalence
- There is evidence of direct association between
ADHD and suicide, with overlapping symptoms such
as impulsiveness, disruptive behavior,
irritability, and problems with the law1,2,3 - Significant relationship to comorbid psychiatric
illnesses - Depression, conduct disorder, substance abuse,
and bipolar disorder

30Suicidal Ideation and BehaviorCONCERTA
PostmarketingAugust 2000 to June 2005
- 121 reports identified
- 75 nonsuicidal events
- 21 suicidal ideation
- 18 suicide attempts
- 7 fatal outcomes
11 hospitalizations
31Postmarketing Reports of Fatal Outcomes August
2000 to June 2005
- 7 fatal outcomes
- ADHD treated
- 5 suicides
- 3 pediatric
- 2 adults
- Non-ADHD treated
- 1 overdose
- 1 intentional misuse/abuse
- All suicide cases had contributing factors
32Observed vs Expected SuicidesAges 10 to 19 Years
- Observed suicides 3
- Expected number of suicides 1201
- CONCERTA exposure 2,610,000 patient-yr2 (10 to
19 yr olds) - US population rate of suicide 4.6 per 100,000
persons(10 to 19 yr olds)
1. US population rate CONCERTA exposure
expected number. 2. 75 of total pediatric
exposure.
33Analysis of Rechallenge and Dechallenge Cases
CONCERTA PostmarketingAugust 2000 to June 2005
- 3 rechallenges
- No hospitalizations
- No suicide attempts (only ideation)
- 2 confounded
- 15 dechallenges
- 2 suicide attempts
- 9 had confounders
- 1 negative rechallenge
34Suicidal Ideation and Behavior ReportsConclusions
- Of 121 reports
- Two thirds of the cases were not suicidal events
- The majority of cases of suicidal ideation and
attempts were not severe - Dechallenge and rechallenge cases did not include
suicide attempts - Observed cases of suicide were significantly less
than expected - These data do not support a causal link between
the suicide events and CONCERTA.
35Overall Conclusions
- Data support a favorable benefit/risk profile for
CONCERTA - Further clarify and better organize the
information contained in our current labeling
utilizing the new physician labeling rule - Continue to analyze the available data and work
with leading experts to evaluate the best methods
for advancing the study of ADHD treatments - Continue and enhance our current educational
efforts to ensure that physicians, patients, and
their families make informed decisions
