Is Remission ofDepressive Symptoms a Realistic

Goal?

Depression: What We Know

• Nearly 15 million American adults experience a major depressive disorder (MDD) episode in any given year

• More common in women

– 10-12 million women have MDD each year

• Men less likely to seek treatment

– 6 million men each year develop MDD

• No racial, ethnic, or socioeconomic boundaries

– Life events and environmental factors can trigger an episode or prevent recovery

– Similar to heart disease: genes and biology raise underlying risk

Kessler RC, et al. Archives of General Psychiatry. 2005;62(6):617-627.

Mark – we used this picture before – do you have anything else that works?

The Tangled Web of Depression

• Depression is an independent factor impacting a range of medical conditions and increasing risk of death and hospitalization:– All cause mortality1

– Acute stroke2

– Diabetes3

– Myocardial infarction4

– Cardiovascular disease5

– Congestive heart failure6

– HIV7

The Impact of Depression

• Of the 30,000 people in the U.S. who commit suicide each year, 60 percent have depression

• Increased risk of substance abuse/dependence

• Increased medical co-morbidities

• Strain on interpersonal relationships

• Estimated U.S. economic burden: $83.1 billion in 2000

• World Health Organization reported that MDD is projected to become the second leading cause of disability worldwide by 2020

Carney RM, Freedland KE. Biological Psychiatry. 2003;54(3):241-247.

One Step Forward, One Step Back

• Less stigma & increased awareness by physicians and public

• Antidepressant use has increased steadily in the U.S. in recent years

• Newer medications have fewer severe side effects and better safety profiles – But efficacy continues to be

questioned

• Despite major advances nearly one-third of patients do not experience substantial relief

7

8

The Goals of Treatment

• Acute phase: remission of depression symptoms

– Complete symptom resolution is the goal

• Maintenance phase: Continued response to the treatment over time

– elimination of residual symptoms

– restoration of prior level of functioning

– prevention of recurrence or relapse

Can we realistically get all patients to remission?

Challenge for Remission – Treatment-Resistant Depression

• Roughly 70 percent of people do not achieve an adequate response to their first trial of antidepressant medication

• Four million patients (30 percent) do not achieve adequate response to treatment and/or do not tolerate medication side effects after multiple treatment attempts with different medications

– Considered to be treatment-resistant depression (TRD)

Consequences of of TRD

• Significantly more inpatient hospitalizations, outpatient office visits, and psychotropic medications1,2,3

• Average annual costs ranged from between 2 times greater1 and 6 times greater3 compared to treatment-responsive patients

• Costs >$42K versus only $6.5K for treatment-responsive patients3

• Significantly greater work loss costs (disability and absenteeism) than treatment-responsive patients1

• Increased direct costs of non-remitters include increased medical utilization for non-psychiatric conditions1,2

13

Strategies for Managing TRD

• Current options for treating resistant depression include:– Increasing medication dose or switching to another

antidepressant

– Adding another drug to augment the current medication treatment

– Adding or switching to psychotherapy and/or non-pharmacologic options

14

15

Where Do We Go From Here?

• Available antidepressant medications are effective for a significant number of MDD patients

• However, approximately one-third of MDD patients don’t adequately benefit from, or can’t tolerate, the available antidepressant medications

• Various combinations and augmentation strategies are frequently utilized to treat resistant MDD

– Some evidence-based

– Most empirical

Understanding How TMS Therapy Works

Mark Demitrack, M.D.

Beyond Pills – What are our Options?

• Lifestyle modifications: Exercise, nutrition, environment manipulations

• Psychotherapy

• Biomedical devices

– Electroconvulsive Therapy (ECT)

– Vagus Nerve Stimulation (VNS)

– Transcranial Magnetic Stimulation (TMS) Therapy

18

Electroconvulsive Therapy (ECT)

• Introduced in 1930s

• Most effective depression treatment

• Works by inducing whole brain “seizure” pattern of neural activation through application of direct electrical current to scalp

• Modern ECT is controlled and painless with anesthesia

• Common adverse events: temporary confusion and memory loss

• Long-term cognitive dysfunction possible

Sackeim HA, et al. Neuropsychopharmacology. 2007;32(1):244-254.

19

Vagus Nerve Stimulation (VNS)

• Approved by FDA in 2005 as adjunct to antidepressant medications

• Electrodes implanted on vagus nerve, pulse generator in chest wall

– Indirect stimulation of the brain

• Evidence of efficacy from non-randomized trial

• Invasive procedure required (surgery) with risks from anesthesia

• MRI contraindication

2020

Transcranial Magnetic Stimulation (TMS)

• Application of electromagnetic induction described by Michael Faraday in 1839– Faraday’s Law: a time-varying

magnetic field induces an electric current that runs perpendicular to the time-varying motion of the magnetic field1,2

• Clinical application: Pulsed magnetic fields can induce electrical currents in brain tissues and neurons3

Effect of TMS on the Brain

Acute Effects– Induces electric current

– Depolarizes neurons in superficial cortex

– Leads to local and trans-synaptic changes in brain activity

Example:

Left prefrontal TMS

23 depressed individuals

Activation demonstrated at site of stimulation and also at synaptically connected cortical and subcortical regions

Summary of NeuroStar TMS Therapy Clinical Evidence

31

• Efficacy established in largest multi-site, randomized, sham-controlled TMS clinical trial conducted to date:

– Primary outcome (MADRS): 22.1% reduction in MADRS total score with active NeuroStar TMS vs 9.1% on sham

– Clinically meaningful effect size = 0.52

• In open label extension study, 1 in 2 patients reached response, 1 in 3 patients achieved remission

• In a 6 month, open-label follow up study that allowed TMS reintroduction if needed, <10% of patients experienced relapse of illness

• Safety and tolerability shown to be excellent

TMS Research by the National Institute of Mental Health

Linda Carpenter, M.D.

33

Independent Research on TMS

• Neuronetics provided NeuroStar devices, but was not involved in study design or implementation

• Tested whether daily left prefrontal rTMS safely and effectively treats MDD– Focus on masking sham conditions

• Well-designed study

– Prospective, multi-site, randomized, active sham-controlled (1:1 randomization)

– 3 weeks of daily weekday treatment followed by continued blinded treatment for up to another 3 weeks in improvers

– Evaluated 199 antidepressant drug-free patients with unipolar, non-psychotic, major depressive disorder

34George et al. Arch Gen Psychiatry 2010; 67(3):507-516.

Confirm # of patients - maybe only 190 actually studied

Confirm # of patients - maybe only 190 actually studied

NIMH Study Findings

• Patients, treaters, and raters effectively masked

• Minimal adverse effects did not differ between active and sham treatment arms

– 88% retention rate (90% sham; 86% active)

• Significant effect of treatment on proportion of remitters (14% active rTMS, 5% sham) (P=0.02)

• Odds of attaining remission 4.2 times greater with active rTMS than sham

– 95% confidence interval, 1.32 – 13.24

• Most remitters had low antidepressant treatment resistance

• Almost 30% of patients remitted in the open-label follow-up

• Conclusion:

Daily left prefrontal rTMS as monotherapy produced statistically significant and clinically meaningful

antidepressant therapeutic effects greater than sham

George et al. Arch Gen Psychiatry 2010; 67(3):507-516.35

NIMH Study Takeaways

• Conducted completely independent of industry

– Used the NeuroStar TMS Therapy system which is the only FDA-cleared device available for the treatment of depression

• Met its a priori primary outcome measure – remission (p=0.02)

• Effect size of treatment benefit is large

– Patients in the active TMS arm had a 4.2 times greater odds of achieving remission

• Included patients with a broad range of treatment resistance

– Patients with one to four prior antidepressant treatment failures were enrolled

View from the Clinic:Finding a Direct Route to

Getting Patients Well

Karl Lanocha, M.D.

37

A Turning Point for My Practice and My Patients

• Changed my practice

• Remarkable success – Even in patients disabled

by depression for years

• Provide TMS therapy exclusively

38

Mark - can we insert some kind of visual to imply a turning point…

Slide is essentially showing how TMS changed the way he practices

What Patients Ask Me

• Will TMS allow me to stop taking medications?

– Simplifies treatment regimen if it does not completely eliminate meds

• Will it bring permanent relief from depression?

– Achieved remission in more than half of patients; infrequently need maintenance therapy

• Is this painful?

– It’s a ‘unique’ experience; never had a pt unable to finish course of treatment; get used to it very quickly; fall asleep after 3-4 tx; oldest patient is 87 who takes a nap;

• How much will this cost?

• Will it change my personality?

39

I’ve included the answers that Lanocha will give, but in presentation, will just list questions, not sub-bullets

Most people are fascinated and want to learn how their brain works

40

Psychotherapy Remains Vital Component of Treatment

• Incorporated into treatment sessions

– Can target behaviors and interpersonal dynamics

• Cognitive-Behavioral Therapy (CBT)

– Focuses on changing negative or irrational thoughts and associated behaviors

– Most validated form of psychotherapy for MDD

• Interpersonal Therapy (IPT)

– Addresses interpersonal issues, relationships

Mark – we used this picture before – do you have anything else that works?

41

How We Decide if TMS is an Option

• Choice of treatment after an initial treatment “failure” depends on many factors, including:– Nature of depressive symptoms

– History of responses to past medication trials

– Medication tolerability

– Side effect profile

– Concurrent medical conditions

– Medication cost

– Likelihood of adherence

– Patient choice

– Physician comfort with managing the treatment

42

TMS Therapy in Clinical Practice

• Non-invasive

• No anesthesia or sedation

• Outpatient procedure easily performed in psychiatrists’ offices

• Approximately 40-minute daily procedure

• 4-6 week treatment course

• Contraindication considerations• Non-removable metallic objects in or

near the head

• Conductive, ferromagnetic, or other magnetic sensitive metals that are implanted or are non-removable within 30 cm of treatment coil

NeuroStar TMS Therapy System User Manual. Neuronetics, Inc: Malvern, PA; 2008.

Quality of Life and Economic Benefits

• NeuroStar TMS shows improvements in standard measures of functional status and quality of life

• When NeuroStar TMS is compared to current standard of care using complex combination antidepressant medications– TMS results in decreased # days lost due to illness, and

increased work productivity,

– TMS results in a net cost savings relative to current pharmaceutical standard of care
