Study to Assess Adverse Events and Change in Disease Activity When Oral ABBV-932 is Added to Antidepressant Therapies in Adult Participants With Generalized Anxiety Disorder

Phase 2
Recruiting
Conditions
Generalized Anxiety Disorder (GAD)
Interventions
Drug: Placebo for ABBV-932
Drug: Antidepressant Therapy (ADT)
Registration Number
NCT06846320
Lead Sponsor
AbbVie
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.

Primary Outcome Measures
NameTimeMethod
Number of Participants with Adverse Events (AEs)Up to approximately 10 weeks

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.

Change from Baseline in the Hamilton Anxiety Scale (HAM-A) Total ScoreUp to approximately 6 weeks

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.

Secondary Outcome Measures
NameTimeMethod
Change from Baseline in Penn State Worry Questionnaire-10 (PSWQ-10) Total ScoreUp to approximately 6 weeks

The PSWQ-10 is a 10-item, participant-reported measure of the tendency of an individual to worry, the excessiveness or intensity of worry, and the tendency for the worry to be generalized and not restricted to a small number of situations. Items are rated from 0 to 6 (0, never; 6, almost always). Total scores range from 0 to 60, with higher scores indicating greater worry.

Change from Baseline in Clinical Global Impression of Severity Scale (CGI-S) Generalized Anxiety Disorder (GAD)Up to approximately 6 weeks

The CGI-S GAD is a single, clinician-reported item that measures the clinician's impression of a participant's current anxiety severity considering their total clinical experience with the participant population. The measure uses a 5-point Likert rating scale, with higher scores indicating greater anxiety severity.

Change from Baseline in the Hamilton Anxiety Scale (HAM-A) Total ScoreUp to approximately 4 weeks

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.

Change From Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total ScoreUp to approximately 6 weeks

The MADRS is a 10-item, clinician-rated scale that evaluates the participant's depressive symptomatology during the past week. Participants are rated on items assessing feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty in concentration, and lack of interest. Each item is scored on a 7-point scale with a score of 0 reflecting no symptoms and a score of 6 reflecting symptoms of maximum severity.

Percentage of Participants in RemissionUp to approximately 6 weeks

Remission is defined as HAM-A total score \<=7.

Percentage of Participants with HAM-A ResponseUp to approximately 6 weeks

HAM-A response is defined as \>= 50% reduction from baseline in HAM-A total score

Percentage of Participants with Clinical Global Impression of Change (CGI-C) GAD Responder Status of "Much Better" or "Moderately Better"Up to approximately 6 weeks

The CGI-C GAD is a clinician-rated scale that measures the overall change in a participant's GAD symptoms since initial receipt of the study medication. The participant is rated on a 7-point Likert scale ranging from "Much better" (1) to "Much worse" (7).
