Transcranial Magnetic Stimulation (“TMS”)

Major Depressive Disorder (“MDD”): Circuits and Neurotransmitters

• Monoamine dysfunction is linked to MDD

• Malfunctioning circuits lead to specific symptoms

Monoamine Neurotransmitters: Serotonin (5-HT); Dopamine (DA); and, Norepinephrine (NE).

Regions implicated in MDD are connected to

the brainstem via monoaminergic circuits

When there is an appropriate amount

of monoamine neurotransmitter activity, neuronal

activity throughout the brain functions

normally.

Neuron

Rapidly pulsed magnetic fields from TMS : • induce a local

electric current in the cortex which depolarizes neurons

• elicit action potentials

• cause the release of chemical neurotransmitters

Neurons are electrochemical cells that

respond to either electrical or chemical stimulation

TMS Directly Depolarizes Cortical Neurons, causing them to fire

Depolarization leads to action potentials in local neurons and

thereby releases neurotransmitters

Depolarization of neurons in the Dorsolateral Prefrontal Cortex causes local neurotransmitter

release

Depolarization of pyramidal neurons in the DLPFC

causes neurotransmitter release in deeper brain

neurons

Activation of deeper brain neurons then exerts secondary effects on remaining portions of targeted mood circuits

These effects are associated with improvements in

depressive symptoms

Optimization of TMS (‘OPT-TMS’) Study

• NIMH-funded, independent of industry • N=190 patients, 4 premier academic sites • Primary outcome measure: % Remission - Active 15% vs. Sham 4% (P =

0.015); Odds Ratio of achieving remission: 4.2 (95%CI, 1.3-13.2)

Major Findings:• 30% of patients achieved remission

in open-label extension phase• Excellent safety, nearly 90% of

patients adherent to acute phase treatment course

Conclusion: “Daily left prefrontal rTMS as monotherapy produced statistically significant and clinically meaningful antidepressant therapeutic effects greater than sham.”

• N=301 patients (ATHF 1 thru 4), 23 sites

• 22.1% reduction in MADRS total score with active NeuroStar TMS vs. 9.1% on sham at 4 weeks (in ATHF = 1 population)

Conclusion: “Transcranial Magnetic Stimulation was effective in treating major depression with minimal side effects reported. It offers clinicians a novel alternative for the treatment of this disorder.”

• Clinically meaningful effect size = 0.52 (in ATHF = 1 population)

• In open label extension study, 1 in 2 patients responded, 1 in 3 patients achieved remission at 6 weeks

• Safety confirmed in 6 month follow-up

Randomized Controlled Trials

In a controlled clinical study, 1 in 2 patients suffering from clinical depression improved significantly, and 1 in 3 patients were completely free of depression symptoms after six weeks of treatment.

Other TMS providers are reporting 80% of their patients treated have significantly improved in their mood, energy and motivation.

EFFECTIVENESS

TheraMind Services TMS Therapy…

Specifically targets the brain circuits involved in mood regulation

Directly depolarizes cortical neurons and modulates neurotransmitter release in the brain

Effects involve both the cortical and deep neural circuits in the brain

Accomplishes these effects without unwanted systemic adverse effects

Summary

Prospective, naturalistic study confirms prior trial results for both clinician- and patient-reported outcomes in real-world practice settings

Some TMS providers are reporting 80% of their patients treated have significant improvement in their mood, energy and motivation. Premier Psych TMS, Walter Duffy, M.D., Lincoln, Nebraska

Patient-reported outcomes showed improvements both in quality of life and functional status

High level of treatment adherence, >80% of patients completed acute treatment

TMS Benefits Patients in Real World Settings

No systemic side effects

No adverse effect on cognition

Most common adverse event associated with treatment was scalp pain or discomfort

- <5% of patients discontinued due to adverse events

Rare risk of seizure with TMS in post-market use (0.003% per treatment, <0.1% per patient)

- (~100,000 treatments in post-marketing experience to date)

Long term safety demonstrated in 6 months follow-up
