                Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population and 1.8% of the pediatric population in the United States. The treatment of the depressive episodes of bipolar disorder in the pediatric population has not been as widely studied as the treatment of depressive episodes in bipolar disorder in adults, therefore pharmacotherapeutic options are limited. Given the change in disease state and safety demonstrated in adults with depressive episodes associate...  Read More

* If LPCN 1154A reduces depressive symptoms in subjects with severe PPD
* How well LPCN 1154A is tolerated and what side effects it may cause
* If LPCN 1154A reduces anxiety symptoms in subjects with severe PPD
