Subjects with specific phobia(s) (as defined in DSM-IV) or dysthymic disorder will be allowed in the study.
2. Subjects must have a HAM-A total score not less than 20 at the screening (V1) and randomization (V2) visits. Subjects must also have a Covi Anxiety Scale score of not less than 9 and a Raskin Depression Scale score not less than 7 at the Screening (V1) visit to ensure predominance of anxiety symptoms over depression symptoms.
3. Otherwise healthy men or non-pregnant, non-lactating women (women must be using a hormonal or barrier method of contraception or be postmenopausal or surgically sterilized). Healthy is defined as no other clinically relevant abnormalities identified by a detailed medical history, full physical examination including sitting blood pressure (BP) and heart rate measurement, 12-lead ECG, and clinical laboratory tests.
4. Age 18 to 65 years, inclusive.
5. All women must have negative pregnancy tests at the Screening (V1) and Randomization (V2) visits.
6. Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
7. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures.

5. Serious suicidal risk per investigator’s judgment.
6. Current use of psychotropic medications that cannot be discontinued 2 weeks prior to randomization. Fluoxetine is prohibited within 5 weeks of randomization. If psychotropics are inadvertently administered during the 2 weeks prior to randomization, the investigator and medical monitor will assess subject’s continued eligibility.
7. Use of drugs, supplements, prescription or nonprescription, or food with psychoactive properties. If the products are inadvertently used during the 2 weeks prior to randomization, the investigator and medical monitor will assess subject’s continued eligibility. If subjects experience significant intolerable anxiety during the final week of the study, the medical monitor may authorize (after discussion with investigator) minimal anxiolytic (e.g. benzodiazepine) medication use.
8. Subjects who have been treated with MAO inhibitors in the 14 days prior to the baseline visit.
9. Regular use of benzodiazepines during the 3 months prior to Screening (for at least 5 out of 7 days per week).
