Official title

A Double-Blind, Randomized, Placebo-Controlled, Parallel-Group, Fixed-Dose, Phase 2 Study Evaluating the Safety and Efficacy of Cariprazine as an Adjunctive Therapy to Antidepressant Therapies (ADTs), in the Treatment of Subjects With Generalized Anxiety Disorder (GAD) Who Have Had an Inadequate Response to ADT Alone

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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 adverse events and the change in disease activity with cariprazine when added to ADTs compared with placebo in adult participants with GAD who have had an inadequate response to 1 or more prior ADTs alone. Cariprazine is an approved drug being developed for the treatment of GAD. The participants are placed into 1 of 4 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 4 chance that participants will be assigned to placebo. Around 1072 participants age 18-65 with GAD and an inadequate response to ADT alone will be enrolled in the study in the United States. After a 2-week screening period, participants will receive daily oral capsules of cariprazine of varying doses or placebo for 6 weeks, followed by a 4-week safety follow-up period for a total study duration of 10 weeks. 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.
