Overview

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

Prevalence and Diagnosis of ADHD

3% to 7% of school-age children in the US1

– 8% to 12% of children worldwide2

Improved care– Clinical recognition: AACAP and AAP guidelines – Pharmacologic treatments considered safe and

effective DSM-IV ADHD core symptoms

– Inattention– Hyperactivity/impulsivity

Significant impairment continues into adulthood

Cardiovascular Safety—Conclusions

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

Definitional Issues—Suicidal Behavior in Pediatric Population

Suicide1 Self-inflicted death with evidence (either explicit or implicit) that the person intended to die

Suicideattempts1

Self-injurious behavior with a non-fatal outcome accompanied by evidence (either explicit or implicit) that the person intended to die

Suicidal ideation1

Thoughts of serving as the agent of one’s own death. Suicidal ideation may vary in seriousness depending on the specificity of suicide plans and the degree of suicidal intent

Selfinjury2

Defined as deliberate non-lethal harming of oneself

Includes cutting, scratching, picking—generally not a suicide attempt

Understanding 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

1. James A, et al. Acta Psychiatr Scand. 2004:110:408-415. 2. Jacobs, Harvard Medical School Guide to Suicide Assessment and Intervention. 1999.3. Rappley M. N Engl J Med. 2005;352:165-173.

C-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

C-31

Postmarketing 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

C-32

Observed 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.

C-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

C-34

Suicidal 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.

C-35

Overall 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
