Slide1

It is the policy of the University of Arkansas for Medical Sciences (UAMS) College of Medicine to ensure balance, independence, objectivity, and scientific rigor in all provided or jointly provided educational activities. All individuals who are in a position to control the content of the educational activity (course/activity directors, planning committee members, staff, teachers, or authors of CME) must disclose all relevant financial relationships they have with any commercial interest(s) as well as the nature of the relationship. Financial relationships of the individual’s spouse or partner must also be disclosed, if the nature of the relationship could influence the objectivity of the individual in a position to control the content of the CME. The ACCME describes relevant financial relationships as those in any amount occurring within the past 12 months that create a conflict of interest. Individuals who refuse to disclose will be disqualified from participation in the development, management, presentation, or evaluation of the CME activity.

Efficacy Data:Major Depressive DisorderFluoxetine receives FDA approval for child and adolescent depression in January 2003 after two positive randomized controlled trialsMany negative studies were unpublishedNIMH-funded study, treatment for adolescents with depression study (TADS): large multi-site trial on adolescent depression becomes available (2004) and is our best gauge on efficacySlide14

RisksWhat was known about safety and risks at the time of the FDA review?What has been learned since?Slide19

FDA Pooled AnalysesData pooled from 24 studiesPharmaceutical data (23 total studies)15 for MDD8 for other mental health disorders (obsessive-compulsive disorder, anxiety, ADHD)TADS (Treatment of Adolescent Depression) studySlide20

What Were Limitations of the Data?Majority of pharmaceutical studies were voluntarily done to obtain exclusivityStudies had small samples and were inadequately powered to detect a rare event like suicidalityStudies were of short duration (<16 weeks)Studies had selection bias due to variations in sample inclusionLess attention was paid to proceduresLimited uniformity across the studiesSlide21

Adverse Events: Data ProblemsFDA data was based on spontaneous reports, not a systematic suicide risk assessment done uniformly across studiesColumbia University needed to reclassify these events, although available data had significant limitations: Feb 2004Slide22

Results: Pooled DataSafetyRelative risk of suicidality (thoughts or behaviors) is 2.19 X greater for drug compared to placebo (95% CI 1.5-3.19); p-value=.00005Conclusion: Suicidality in these children did not occur by chance alone. There is a 2% risk in placebo and a 4% risk with medication: September 2004Slide23

Completed SuicideNo completed suicides in ANY of the acute studiesSlide24

Unit F: Black Box WarningSlide26

The Role of Narratives inthe FDA HearingComparable to case reports (although missing data)NOT CAUSAL !Understand stakeholders’ perspectives (Scientology, lawsuits, etc.)***Many have said thatthe anecdotal reports significantly influenced the decision regarding the FDA’s boxed warningSlide27

2004 Black BoxWarning up to the age of 18Warned of increased suicidalityCalled for weekly visits for 4 weeks, every other week visits for another 8 weeks, and then monthly visitsSlide28

SSRIs and Suicide Slide29

FDA-Recommended Warning Boxand Close MonitoringIn May 2007, the FDA ordered that all antidepressant medications carry an expanded warning box with information re: increased risk of suicidal symptoms in young adults 18-24 years of age“Antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults in short-term studies with major depressive disorder (MDD) and other psychiatric disorders. Short term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24, and there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. This risk must be balanced with the clinical need. Monitor patients closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber.”Slide30

In the 2007 changes to the Warning Box, the FDA discontinued its previous specific recommendations that C&A starting an antidepressant be followed weekly x 4 weeks, then q.o. week x 4 weeks, etc.NOTE: The Warning Box applies not just to antidepressants, but to all drugs with similar mechanisms: e.g., atomoxetine (SNRI approved for ADHD) has a Warning Box.Suicidality may occur with medications without a Warning Box, i.e. even though stimulants are not officially “labeled” as linked to suicidality, they can cause emotionality/over-arousal that might in some vulnerable patients present as suicidality.FDA-Recommended Warning Boxand Close MonitoringSlide31

The Risk-Benefit RatioSlide32

Pros and Cons to the Warning Box Pros Encourages consideration of risks/benefits before prescribingEncourages partnerships with familyEncourages exploration of all other available optionsMay result in more appropriate monitoring of patients Cons Increased Fear: patientsIncreased Fear: parentsIncreased Fear: prescribersSeriously impaired children may go untreatedChildren may be treated inappropriately with alternative medicationsSlide33

Interpretation

SSRIs

efficacious for depression, OCD, and non-OCD anxiety. Benefits of SSRIs much greater than risks for suicidality (Bridge et al., JAMA 2007:18,297:1683-96)

Antidepressants may slightly increase rates of suicidal “events” (thoughts, attempts). Given 2,000,000 events, this is an important public health problem

Antidepressants speed recovery and improve functional outcomes, esp. if combined with CBT

Antidepressants likely prevent death by suicide, probably via effective treatment of depression

Co-administered CBT may protect against suicidal events and assists in monitoringSlide34

Clinical RealitiesWe need to help anxious and depressed childrenSSRIs play a key role in several clinical scenarios: Partial response to psychotherapyLack of availability of resourcesImprove speed of responseSSRIs are effectiveBoth Fluoxetine & Escitalopram have several positive studies for MDD and have FDA approvalThree SSRIs with FDA approval for OCDSSRI data favorable for other Anxiety DisordersA risk-benefit ratio for one child may be different for anotherSlide35

Now What?Slide36

Summary: Clinical RecommendationsA careful assessment is criticalPartner with caregivers: Families and patients need to be fully informed about the risks and benefits of antidepressant treatment. Antidepressants should be initiated at a low dose and titrated as indicated and tolerated Slide37

Always Monitor:
