|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To evaluate the efficacy of pregabalin versus placebo in relieving the symptoms of Generalized Anxiety Disorder as measured by Hamilton Anxiety Rating Scale (HAM-A) 2. Evaluate the safety of pregabalin versus placebo based upon the nature, incidence and severity of adverse events
|
|
E.2.2 | Secondary objectives of the trial |
1. Evaluate response rates between pregabalin and placebo (defined as equal or > 50% improvement in HAM-A total score from baseline to last observation on double-blind treatment) 2. Compare the effects of pregabalin and placebo in relieving the symptoms of depression as measured on by the 17-item Hamilton Depression Rating Scale (HAM-D) 3. Compare the effects od pregabalin and placebo on the clinician-rated Clinical Global Impression of Change (CGIC) 4. Compare the effects of pregabalin and placebo on symptoms of psychopathology and psychological distress using the 90-Item Symptom Checklist-Revised (SCL-90-R) total score and subscales 5. Compare the effects od pregabalin and placebo on cognition using the Mini-Mental State Examination of Folstein (MMSE).

E.3 | Principal inclusion criteria |
Male or nonfertile female outpatients 65 years or older with a DSM-IV diagnosis of generalized anxiety disorder (GAD) and confirmed using a structured clinical interview (MINI). Patients will have a Hamilton Anxiety Rating Scale (HAM-A) score of 20 at screening and randomization. Patients will have an Mini-Mental State Examination of Folstein (MMSE) total score 24.
