Study summary

The primary purpose of this study is to evaluate whether treatment with (SEROQUEL SR) quetiapine fumarate sustained release (SR) for 9 weeks compared to placebo will improve elderly patients with generalised anxiety disorder.

PLEASE NOTE: Seroquel SR and Seroquel extended release(XR) refer to the same formulation. The SR designation was changed to XR after consultation with FDA.

What researchers measure

Primary outcomes

  1. Change in the Hamilton Rating Scale for Anxiety (HAM-A) Total Score

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

    Time frame: Randomization to Week 9

Secondary outcomes

  1. Change in Health-related Quality of Life as Measured by Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) Percent Maximum Total Score

    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

    Time frame: Randomization to Week 9

  2. Change in the Clinical Global Impression - Severity of Illness (CGI-S) Score

    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

    Time frame: Randomization to Week 9

  3. Change in Psychic Anxiety Factor as Measured by HAM-A Psychic Cluster Score

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

    Time frame: Randomization to Week 9

  4. Change in Somatic Symptoms as Measured by HAM-A Somatic Cluster Score

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

    Time frame: Randomization to Week 9

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

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

    Time frame: Week 9

  6. Number of Patients Reaching Hamilton Rating Scale for Anxiety (HAM-A) Remission

    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

    Time frame: Week 9

  7. Change in Montgomery-Asberg Depression Rating Scale (MADRS)

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

    Time frame: Randomization to week 9

  8. Change in the Visual Analogue Scale (VAS) Measuring Pain

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

    Time frame: Randomization to week 9

  9. Safety and Well Tolerated as Measured in Adverse Event

    Number of patients have at least one adverse event

    Time frame: From the start of treatment to last dose plus 30 days

  10. Safety and Well Tolerated as Measured by Extra Pyramidal Symptoms (EPS)

    Number of patients have adverse events associated with EPS

    Time frame: From start of the study teatment to last dose plus 30 days
