About

The study proposes to conduct a pilot study of biological predictors of lurasidone response in bipolar depression.

Full description

The study proposes to enroll 20 participants with a bipolar disorder who are currently in an episode of major depression.Magnetic resonance imaging (MRI), recordings of brain electrical activity (EEG), and psychological testing to explore possible predictors of lurasidone treatment response will be conducted. Blood samples will be collected for a future study of blood protein predictors of response. After testing, participants will receive an open-label 8-week trial of lurasidone (Latuda™) at approved dosage levels. Participants who attain remission of their major depressive episode will be eligible for a six-month continuation phase to explore predictors of sustained response to continuation treatment. Data analyses will use statistical testing to explore potential biological predictors of lurasidone response. This will provide a framework for clarifying which patients are best suited to this treatment and begin to develop a model for precision treatment of this difficult-to-treat disorder.

6. Provides informed consent

Exclusion criteria

1. Current drug or alcohol abuse/dependence, except nicotine (within 6 months for dependence; 2 for abuse)

2. Taking any of the following exclusionary medications: antipsychotics, anticonvulsants, mood stabilizers, stimulants, antidepressant medications, medications with significant interactions with lurasidone, except during the washout prior to testing and blood collection

3. Unstable medical condition, including significant liver disease, hypothyroidism (i.e., condition not adequately stabilized for 3 months), and conditions likely to require hospitalization or with a life expectancy of < 6 mos.*

4. Patients considered at significant risk for suicide

5. Inadequate understanding of English

6. Currently pregnant or breast-feeding; fecund women not using adequate contraceptive methods; plan to become pregnant within 12 months

7. Contraindications to MRI (e.g. ferromagnetic body implants, history of metal working, etc.)

8. Have epilepsy, neuromuscular disorder, or tardive dyskinesia

9. Require immediate hospitalization for psychiatric disorder

10. Require medications for a general medical condition that contraindicate any study medication**

11. Receiving or have received during the index episode vagus nerve stimulation, electroconvulsive therapy, transcranial magnetic stimulation, or other somatic treatments

12. Allergy to, or other medical contraindication to lurasidone treatment

13. Currently enrolled in another research study, and participation in that study contraindicates participation

14. Clinically significant screening laboratory abnormalities (* see below)

15. Currently taking an effective mood stabilizer and/or antidepressant regimen

16. Inability to undergo a three week medication-free period, including history of significant clinical deterioration from past periods off medication or when medication dosage was reduced, including mania, severe depression, etc.

17. Any reason not listed herein that would make participation in the study hazardous *Medical criteria for exclusion:

    • Untreated hypertension: > 140/90 Torr on repeated measurement (If hypertension becomes stabilized, subject may enroll in study)
    • Hepatitis: any liver function test > 2x the upper limit of normal
    • Renal failure: estimated Glomerular Filtration Rate (eGFR, corrected for body surface area) repeatedly < 30 mL/min
    • Hypothyroidism: thryrotropin stimulating hormone level > upper limit of normal (unless accompanied by other euthyroid indices and the confirmation by an internist or endocrinologist that this does not represent hypothyroidism)
    • Anemia: hemoglobin < 10 grams/deciliter (borderline hemoglobin must be of known origin, stable, and not clinically significant)
