Descriptive Information
Brief Title  ICMJE Evaluation of Depression Symptoms and Brain Activity Associated With Response to Treatment of Depression
Official Title  ICMJE Factors of Treatment Response in Major Depressive Disorder
Brief Summary This study will use measurements of depression symptoms and brain activity to determine what factors may influence an individual's response to treatment for depression.
Detailed Description We are using depression symptom measurements and measurements of brain electrical activity (EEG) to determine what factors may influence whether a patient is likely to show a response to antidepressant medication, placebo, or only clinical visits (without the use of pills) during a treatment trial for depression.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 4
Study Design  ICMJE Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Condition  ICMJE Depression
Intervention  ICMJE
  • Drug: Venlafaxine (Effexor), Duloxetine (Cymbalta), Escitalopram (Lexapro)
    Subjects assigned to the placebo (PBO) or medication (MED) condition will enter double-blind treatment with either venlafaxine XR, duloxetine, escitalopram, or placebo after lead-in. They will undergo the same schedule, structure, and intensity of visits as in the ICI condition, but also will be randomized to receive treatment with a pill. Subjects randomized to medication will be started on one tablet each morning of either venlafaxine XR 75 mg., duloxetine 30 mg., or escitalopram 10 mg. Dosages will be increased in a double-blinded manner by increasing the number of pills administered by one pill every three to five days until the final dose is achieved (225 mg., 90 mg., and 30 mg. respectively for venlafaxine XR, duloxetine, and escitalopram). In order to maintain blinding during dosage increase, the number of tablets of placebo will be increased every three to five days as well.
  • Other: Placebo
    Subjects assigned to the placebo (PBO) or medication (MED) condition will enter double-blind treatment with either venlafaxine XR, duloxetine, escitalopram, or placebo after lead-in. They will undergo the same schedule, structure, and intensity of visits as in the ICI condition, but also will be randomized to receive treatment with a pill. Subjects randomized to medication will be started on one tablet each morning of either venlafaxine XR 75 mg., duloxetine 30 mg., or escitalopram 10 mg. Dosages will be increased in a double-blinded manner by increasing the number of pills administered by one pill every three to five days until the final dose is achieved (225 mg., 90 mg., and 30 mg. respectively for venlafaxine XR, duloxetine, and escitalopram). In order to maintain blinding during dosage increase, the number of tablets of placebo will be increased every three to five days as well.
  • Behavioral: Interpersonal Clinical Interaction (ICI)
    Interaction with and assessment by clinical research personnel on a fixed schedule, with the pharmacotherapeutic alliance assessed both by research personnel and subjects.
Study Arms  ICMJE
  • Active Comparator: MED

    For medication treatment, three different types were utilized and assigned specifically to each subject depending on their condition:

    MED 1: Venlafaxine XR. MED 2: Duloxetine (Cymbalta) MED 3: Escitalopram (Lexapro)

    Intervention: Drug: Venlafaxine (Effexor), Duloxetine (Cymbalta), Escitalopram (Lexapro)
  • Placebo Comparator: Placebo (PBO)
    Subjects enrolled will receive interpersonal clinical interaction (ICI) along with a placebo treatment (Interaction and assessment as in ICI plus double blinded treatment with placebo tablets).
    Intervention: Other: Placebo
  • Interpersonal Clinical Interaction (ICI)
    Subjects assigned to the interpersonal clinical interaction (ICI) will undergo a one-week waiting period after the initial assessment. Visits will involve a session with a research nurse that will be approximately 20 minutes in length; visits at baseline, end of lead-in, and 1, 2, 4, and 8 weeks also will include a brief (5-10 minutes) meeting with a physician.
    Intervention: Behavioral: Interpersonal Clinical Interaction (ICI)
