Outcomes

Primary Outcome Measures

The efficacy of PD 0332334 in the treatment of GAD will be measured by the change in the Hamilton Anxiety Rating Scale (HAM-A) total scores from baseline observed following 8 weeks of double-blind treatment.
The safety and tolerability of PD 0332334 in subjects with GAD will be monitored in this study.

Secondary Outcome Measures

Response rate on the clinician-rated CGI-I at Week 1 and Week 8.
Change from Baseline to Week 8 on the Medical Outcomes Study-Sleep Scale (MOSS-SS) subscales.
Change from Baseline to Week 8 on the Sheehan Disability Scale (SDS) total score.
Change from Baseline to Days 2-8 and Weeks 2, 4, 6, 8 on the DAS-A (total score).
Response rate on the HAM-A at Week 1 and Week 8.
Change from Baseline in the somatic subscale score of the HAM-A (Items 7-13) at Week 8.
Remission rate based on the HAM-A at Week 1 and Week 8.
Response rate on the patient-rated PGI-C at Week 8.
The "Week 1 Sustained Responder" rate based on the HAM-A (where "Week 1 Sustained Responders" are defined as subjects with a 50% or greater improvement from baseline on the HAM-A total score at Week 1 that is sustained until the Week 8 visit).
Change from Baseline in HAM-A total score at Weeks 1, 2, 4, and 6.
Change from Baseline in the 17-item HAM-D total score at Weeks 1, 2, 4, and 8.
Change from Baseline to Week 8 on the Sheehan Disability Scale subscales.
Change from Baseline in CGI-S at Week 8.
Change from Baseline in the psychic subscale score of the HAM-A (Items 1-6 and 14) at Week 8.
Change from Baseline to Week 8 on the Medical Outcomes Study Sleep Scale (MOS-SS) total score.
Change from Baseline to Week 8 in the Q-Les-Q General Activities Score.
Change from Baseline to Week 1 on the Medical Outcomes Study Sleep Scale (MOS-SS) total score.
Change from Baseline to Days 2-8 and Weeks 2, 4, 6, 8 on the GA-VAS (diary).
