Study to Evaluate the Safety and Efficacy of PEER Interactive Versus Treatment as Usual in Subjects With a Primary Diagnosis of Depression

This study is prospective in nature. Subjects in the control group will be treated according
to treatment as usual and best judgment of the treating physician. For the experimental group
the treating physician will follow the guidance of the subject's PEER Interactive Report as
regards sensitivity to on-label medications and classes of medication.

The subjects will be washed out of all current medications prior to having an EEG, which is
necessary to generate the PEER Interactive Report. The wash out period for outpatients is no
longer than 14 days.

The subjects will be followed for 6 months after the initial treatment, or until the patient
has achieved maximum medical improvement (MMI). The patient will be seen on a routine basis
and assessments will be made at each interaction to evaluate the patient's improvement in
mental health. The subjects will also be closely evaluated to determine if they are
experiencing any psychiatric specific adverse events. The investigator is allowed to treat
the patient according to their best medical judgment, which may include adding or changing
medications, seeing the patient more frequently, or other interventions such as the use of
sleep aids.
