The goal of this study is to learn how psychedelics may help symptoms of depression and anxiety. Participants with major depressive disorder experiencing symptoms of depression and anxiety will receive one dose of either a drug related to psilocybin or a placebo. Assessments include interviews, self-report questionnaires, EEG and fMRI to measure symptoms and brain function.
Generalized anxiety disorder (GAD) is usually treated with antidepressant therapy (ADT); however, sometimes ADTs alone are not enough to adequately treat GAD. The purpose of this study is to assess how safe and effective ABBV-932 is when added to the antidepressant therapies in adult participants with GAD who have had an inadequate response ADTs.
ABBV-932 is an investigational drug being developed for the adjunctive treatment of GAD. Participants will be randomly assigned to receive ABBV-932 or Placebo in addition to their currently prescribed ADTs. There is 1 in 3 chance of participants assigned to Placebo. Approximately 315 adult participants with GAD and inadequate response to ADTs will be enrolled in approximately 50 sites in the United States and Puerto Rico.
Participants will receive oral capsules of ABBV-932 or matching placebo in addition to their prescribed ADT for 6 weeks and then will be followed for an additional 4 week follow-up period.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular 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.
This is a multicenter, randomized, double-blind, placebo-controlled study to assess the efficacy, safety, and tolerability of ITI-1284 as monotherapy treatment in patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) criteria for GAD in patients who have had inadequate response to generalized anxiety disorder treatment.
