Primary Outcome Measures
NameTimeMethod
Change in the Hamilton Rating Scale for Anxiety (HAM-A) Total ScoreRandomization to Week 9

HAM-A total score ( 0-56 units), 0 is the best, Change : score at week 9 minus score at randomization

Secondary Outcome Measures
NameTimeMethod
Change in Health-related Quality of Life as Measured by Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) Percent Maximum Total ScoreRandomization to Week 9

Q-LES-Q total score is the sum of the first 14 items of Q-LES-Q, and this total score is converted to a % maximum total score by : (Q-LES-Q total score -14) /56 x 100%, Larger values indicate a higher perceived quality of life enjoyment and satisfaction.

Change : percentage at week 9 minus percentage at randomization

Change in the Clinical Global Impression - Severity of Illness (CGI-S) ScoreRandomization to Week 9

CGI-S score is accessed on a seven-graded scale ranging from most extremely ill/ very much worse (7) to normal/very much improved (1) , 1 is best Change : score at week 9 minus score at randomization

Change in Somatic Symptoms as Measured by HAM-A Somatic Cluster ScoreRandomization to Week 9

HAM-A somatic cluster score (0-28), 0 is the best Change : score at week 9 minus score at randomization

Change in Psychic Anxiety Factor as Measured by HAM-A Psychic Cluster ScoreRandomization to Week 9

HAM-A psychic cluster score ( 0-28), 0 is the best Change : score at week 9 minus score at randomization

Hamilton Rating Scale for Anxiety (HAM-A) Response.Week 9

HAM-A response, defined as 50% or greater reduction from randomization in HAM-A total score.

Number of Patients Reaching Hamilton Rating Scale for Anxiety (HAM-A) RemissionWeek 9

HAM-A remission, defined as HAM-A total score less or equal to 7. An indicator of HAM-A remission is calculated as:

* If HAM-A total score≤7, THEN indicator=1

* If HAM-A total score \>7, THEN indicator=0

Change in Montgomery-Asberg Depression Rating Scale (MADRS)Randomization to week 9

MADRS total score (0-60), 0 is best Change : score at week 9 minus score at randomization

Change in the Visual Analogue Scale (VAS) Measuring PainRandomization to week 9

Visual Analogue Scale (VAS) measuring pain (0-100 mm), 0 is best Change : scale at week 9 minus scale at randomization

Safety and Well Tolerated as Measured in Adverse EventFrom the start of treatment to last dose plus 30 days

Number of patients have at least one adverse event

Safety and Well Tolerated as Measured by Extra Pyramidal Symptoms (EPS)From start of the study teatment to last dose plus 30 days

Number of patients have adverse events associated with EPS
