Multicenter, Open-label Study to Evaluate the Long-term Safety and Tolerability of ABBV-932 in Subjects With Depressive Episodes Associated With Bipolar I or II Disorder
Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population in the United States. The purpose of this study is to assess how safe and effective ABBV-932 is in treating participants with depressive episodes associated with bipolar I or II disorder. ABBV-932 is an investigational drug being developed for the treatment of depressive episodes in adult participants with bipolar I or II disorder. Participants with bipolar I or II disorder who are currently experiencing a depressive episode will enter the study and be treated with open-label ABBV-932. Approximately 200 adult participants with bipolar I or II disorder will be enrolled in approximately 50 sites in the United States and Puerto Rico. Participants will receive oral capsules of ABBV-932 for a 26-week treatment period. The treatment period will be followed by a safety follow-up (SFU) period of 30 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regularly scheduled visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
