NCT06846320

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Number of Participants with Adverse Events (AEs)

    An AE is defined as any untoward medical occurrence in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

    Up to approximately 10 weeks

  • Change from Baseline in the Hamilton Anxiety Scale (HAM-A) Total Score

    The HAM-A is a 14-item, clinician-reported measure used to quantify and categorize the participant's anxiety over the past week. Items are rated on a 5-point Likert rating scale. The HAM-A total score ranges from 0 to 56, with higher scores indicating greater anxiety severity.

    Up to approximately 6 weeks

Secondary Outcomes (11)

  • Change from Baseline in Penn State Worry Questionnaire-10 (PSWQ-10) Total Score

    Up to approximately 6 weeks

  • Change from Baseline in Clinical Global Impression of Severity Scale (CGI-S) Generalized Anxiety Disorder (GAD)

    Up to approximately 6 weeks

  • Change from Baseline in the Hamilton Anxiety Scale (HAM-A) Total Score

    Up to approximately 4 weeks

  • Change From Baseline in Montgomery-Ã…sberg Depression Rating Scale (MADRS) Total Score

    Up to approximately 6 weeks

  • Percentage of Participants in Remission

    Up to approximately 6 weeks

  • +6 more secondary outcomes
