October 21, 2020 updated by: ChemRar Research and Development Institute, LLC
A Multicenter, Randomized, Double-blind, Placebo- and Active- Controlled Study to Assess the Efficacy and Safety of CD-008-0045 in Patients With Generalized Anxiety Disorder
This is a multicenter, randomized, double-blind, placebo- and active-controlled study to assess the efficacy and safety of CD-008-0045 in patients with generalized anxiety disorder (GAD).
Each patient will participate in the study for the period of approximately 37 weeks: Screening and Run-in period: 1 week; Study Treatment period: 32 weeks; Follow-up period: 4 weeks.

Detailed Description
The study drug CD-008-0045 has a multi-targeted activity, i.e., able to inhibit adrenergic, dopamine, serotonin, and histamine receptors, thus allowing to assume its wide therapeutic potential.
At Screening, the patients who meet the inclusion/exclusion criteria will be included into one-week single-blind Placebo Run-in period.
At Week 0 the patients will be start double-blind Placebo and active comparator treatment period.
The patients will be randomized to receive CD-008-0045 40 mg daily or Placebo or Afobazol (fabomotizole) for 8 weeks.
After that, there will be an open-label treatment period for 26 weeks.
The potential withdrawal syndrome will be assessed during four-week Follow-up Period.
