Brief Summary:

The investigators will conduct an 8-week, non-randomized, open-label study of brexpiprazole in 20 persons with bipolar I or II disorder, depressed mood state. Primary aim will be to assess if brexpiprazole is associated with a reduction in depressive symptom severity using the Montgomery-Asberg Depression Rating Scale (MADRS). Secondary aims will include an assessment of the following in patients with bipolar disorder taking brexpiprazole: manic symptoms, cognition, safety and tolerability of brexpiprazole, and quality of life.

Subjects will be discontinued from the study if any of the following conditions occurs: change in diagnosis to other than bipolar I or II disorder, development of active suicidal or homicidal ideation with plan and intent, worsening of mood symptoms, that in the opinion of the investigators requires discontinuation, pregnancy, development of severe life-threatening medical condition, involuntary psychiatric hospitalization or incarceration.

Primary Outcome Measures :
  1. The Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: Baseline through week 8 ]
    The Montgomery-Asberg Depression Rating Scale is used to assess depressive symptom severity. There are 10 items and each item is rated from 0 to 6 (increasing severity) based on the assessment of symptoms within the past 7 days. Scoring is assisted by descriptive anchors that serve as useful guides at 0,2,4, 8. Odd numbers (1,3,5) between the descriptive anchors are also meant to be scored. Highest possible MADRS score is 60. Lowest possible MADRS score is 0. MADRS is scored by taking the sum of the scores for each item. A higher score is indicative of more acute depressive symptoms.

Secondary Outcome Measures :
  1. Young Mania Rating Scale (YMRS) [ Time Frame: Baseline through week 8 ]
    Young Mania Rating Scale is an observer-rated measure of mania symptoms. It has 11 items and each items has 5 defined anchor points with increasing severity that describe the symptom characteristics. YMRS is scored by taking sum of the scores for the 11 items. A higher score indicative of more acute manic symptoms. Seven of the items are scored between 0 and 4. Four items allow for scoring between anchor points (ranging 1 to 8). Maximum score is 60 and minimum score is 0.

  2. Rey Auditoy Verbal Learning Test [ Time Frame: Baseline through week 8 ]
    Rey Auditory Verbal Learning Test (RAVLT) is a test of verbal learning and declarative memory. During the test, 15 nouns that are read aloud for 5 consecutive trials. Each trial is followed by a free recall test (participant is asked to recall the words that were just read to them). The sum of correctly recalled words across 5 trials is called the total raw score. On completion of Trial 5, an interference list of 15 words (List B) is presented, followed by a free recall test of that list. After a 20-min delay, the examinee is again required to recall the words from list A - this is called the delay raw score. The raw scores on both the total recall and the delay trials (number of words correct across trials 1-5) are converted to standardized T-scores (Mean=50; SD=10; range 20-100) based on participant age and gender. The scores below are presented as T-scores, with higher scores indicative of better performance.

  3. Stroop Task [ Time Frame: Baseline through week 8 ]
    The Stroop task evaluates attention, speed, and accuracy of thinking. Stroop task consists of three separate trials: word, color, and color-word (CW) naming. For each trial, a raw score (correct number of words named) is recorded. The raw score for each trial is converted to a T-score based on participant's age and education level. The possible T-scores range from 15-85 for the word trial, 8-92 for the color trial, and 3-98 for the color-word trial. The interference score (Inter) is also derived from the color-word score, with T-scores ranging from 21-80. Higher numbers indicate better performance. The entered values represent T-scores.

  4. Trail Making Test (TMT) [ Time Frame: Baseline through week 8 ]
    The Trail Making Test (TMT) measures attention, speed, and accuracy. TMT consists of two parts: Trails A and Trails B. The performance on each test is measured in seconds and represents how quickly a participant can connect the numbers (Trails A) and the numbers and letters (Trails B) together. The number of seconds it takes to complete each part of TMT is converted to a T-score based on gender, age, race, and education. The T-scores range from 0-100 with higher scores indicating better (faster) performance. The entered data are presented as T-Scores.

  5. Systematic Assessment For Treatment Emergent Events [ Time Frame: Baseline through week 8 ]
    The Systematic Assessment for Treatment Emergent Effects (SAFTEE) is a self-report scale used in clinical trials and is designed to evaluate the degree to which each possible side effect is bothersome to a participant. There are 55 items on the scale (each item represents a different side effect), with each item rated on a 4-point scale such as "not bothersome - 0 (zero)", "mildly bothersome - 1", "moderately bothersome - 2", "severely bothersome - 3". The total possible range of scores on the scale is 0-165. The higher scores indicate a higher degree of being bothered by various side effects.

  6. Columbia Suicide Severity Rating Scale [ Time Frame: Baseline through week 8 ]
    The Columbia Suicide Severity Rating Scale (C-SSRS) is a structured interview and rating scale used to measure suicidal thoughts and behaviors. Actual attempts, interrupted attempts, and aborted attempts are measured as positive integers (zero and above). The minimum value for the actual, interrupted, and aborted attempt is zero (reflecting no past suicidal behavior). There is no maximum scale value, as the number of attempts differs for each participant. The entered values represent the average number of actual, interrupted, and aborted attempts in the group. Higher values reflect a higher number of attempts experienced by each participant (equivalent to a worse outcome).

  7. Abnormal Involuntary Movement Scale [ Time Frame: Baseline through week 8 ]
    The Abnormal Involuntary Movement Scale (AIMS) is an assessment of movements to determine any long-term drug induced movement disorders.There are 10 items on the scale with scores ranging from 0-4 (0 None/Normal, 1 minimal, 2 mild, 3 moderate,4 severe). 4 items assess facial and oral movements, 2 items measure extremity movements, 1 item measures trunk movements, and 3 items measure global judgments regarding symptoms assessed. A total score is the sum of scores for items assessing facial and oral movements, extremity movements, and trunk movement (scores ranging from 0-28), with 0 being the lowest score, and 28 being the highest score. A higher score is indicative of a higher severity in symptomatology.

  8. Barnes Akathisia Scale [ Time Frame: Baseline through week 8 ]
    The Barnes Akathisia Scale (BAS) is an assessment of movements to determine any short-term drug-induced movement disorders. There are 5 items.Items 1-3 are rated from a scale of 0-3 with 0 indicating the least severity, and 3 indicating the highest severity of symptoms. Item 4 is a global assessment of symptoms assessed and the severity is assessed on a scale of 0-5, with 0 indication least severity and 5 indicating the most severity.The total score is the sum of all the item scores (scores ranging from 0-14).With higher scores reflecting worse outcome.

  9. Simpson Angus Scale [ Time Frame: Baseline through week 8 ]
    The Simpson Angus Scale (SAS) measured drug-induced movement side effects. There are 10 items on the scale, with each item scored on a scale of 0-4 (least to most severe). The total possible range of scores across all items is 0-40, with higher scores indicative of worse outcome.

  10. Quality of Life in Bipolar Disorder (QOLBD) [ Time Frame: Baseline and at week 8 ]
    The Quality Of Life in Bipolar Disorder (QOLBD) is a measure of the quality of life in patients with bipolar disorder. All questions on the scale ask about a range of experiences, behaviors, and feeling related to the quality of life. For each question, a participant is asked to indicate how much they agree with each question. The scale consists of 12 questions, with each question measured on a 5-point scale, such as "strongly disagree - 1", "disagree - 2", "neutral - 3", "agree - 4", "strongly agree - 5". The total possible range of scores on the scale is 12-60. Higher scores indicate better quality of life.

  11. The Inventory of Depressive Symptomatology Self-Report (IDS-SR30) [ Time Frame: Baseline through week 8 ]
    An 30 item inventory self report assessing depressive symptoms and mood, within the past seven days. With the score range of 0-90 with higher scores indicating worse outcome.

Other Outcome Measures:
  1. High Sensitivity C-Reactive Protein (Hs-CRP) [ Time Frame: Baseline and at week 8 ]
    high sensitivity C-Reactive Protein values will be used to measure inflammation
