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 randomized to receive CD-008-0045 60 mg daily, CD-008-0045 40 mg daily or Placebo for 8 weeks.
