All rights reserved. What Were Limitations of the Data? • Majority of pharmaceutical studies were voluntarily done to obtain exclusivity • Studies had small samples and were inadequately powered to detect a rare event like suicidality • Studies were of short duration (<16 weeks) • Studies had selection bias due to variations in sample inclusion • Less attention was paid to procedures • Limited uniformity across the studies Copyright © The REACH Institute. All rights reserved. Adverse Events: Data Problems • FDA data was based on spontaneous reports, not a systematic suicide risk assessment done uniformly across studies • Columbia University needed to reclassify these events, although available data had significant limitations: Feb 2004 Copyright © The REACH Institute. All rights reserved. Results: Pooled Data • Safety – Relative risk of suicidality (thoughts or behaviors) is 2.19 X greater for drug compared to placebo (95% CI 1.5-3.19); p-value=.00005 – Conclusion: Suicidality in these children did not occur by chance alone.

FDA-Recommended Warning Box and Close Monitoring • In 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.” Copyright © The REACH Institute. All rights reserved. FDA-Recommended Warning Box and Close Monitoring • 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.

Pros and Cons to the Warning Box Cons Pros • Encourages consideration of risks/benefits before prescribing • Encourages partnerships with family • Encourages exploration of all other available options • May result in more appropriate monitoring of patients • Increased Fear: patients • Increased Fear: parents • Increased Fear: prescribers • Seriously impaired children may go untreated • Children may be treated inappropriately with alternative medications Copyright © The REACH Institute. All rights reserved. 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 monitoring Copyright © The REACH Institute. All rights reserved. Clinical Realities • We need to help anxious and depressed children • SSRIs play a key role in several clinical scenarios: – Partial response to psychotherapy – Lack of availability of resources – Improve speed of response – SSRIs are effective • Both Fluoxetine & Escitalopram have several positive studies for MDD and have FDA approval • Three SSRIs with FDA approval for OCD • SSRI data favorable for other Anxiety Disorders • A risk-benefit ratio for one child may be different for another Copyright © The REACH Institute. All rights reserved. Now What? Copyright © The REACH Institute. All rights reserved. Summary: Clinical Recommendations • A careful assessment is critical • Partner 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 Copyright © The REACH Institute. All rights reserved. Always Monitor: • Treatment-emergent suicidality / Form a Safety Plan with families (see F1.1-1.4) • Sudden changes in mood or behaviour • Compliance • Adverse events • Treatment emergent comorbidity Copyright © The REACH Institute.
