Bipolar disorder: recent clinical trials and emerging therapies for depressive episodes and maintenance treatment

International audienceBipolar disorder (BD) is one of the world's ten most disabling conditions.

We reviewed 30 recent clinical trials in depressive episodes (eight tested compounds) and 14 clinical trials in maintenance treatment (ten tested compounds).

The current BD pipeline is encouraging with promising new compounds, acting on novel pharmacological targets and on specific aspects of bipolar depression
