Bipolar disorder is a mental illness that affects nearly six million adults in the United States. It is characterized by episodes of mania (bipolar I) or hypomania (bipolar II) interposed with episodes of depression. As many as half of these patients suffer from Bipolar II disorder.
Bipolar depression remains a significantly underserved medical need.
Bipolar depression is the most common clinical presentation of bipolar disorder. These episodes tend to last longer, recur more often and are associated with a worse prognosis than the manic/hypomanic episodes. Bipolar depression remains a significantly underserved medical need with only a few FDA-approved treatment options available.
