Study Details

Study Description

Brief Summary

The purpose of this study is to compare the response of veterans with PTSD without an optimal response to paroxetine to quetiapine augmentation versus placebo.

Condition or DiseaseIntervention/TreatmentPhase
Phase 4

Detailed Description

This is a two-site study designed to evaluate the efficacy and safety of quetiapine augmentation of paroxetine treatment in veterans with PTSD who have failed to respond to paroxetine treatment.

In Phase I, eligible patients will take open-label paroxetine (up to 60 mg daily) for 8 weeks. Patients who are refractory (less than 30% reduction in CAPS scores or a minimum CAPS score of 50 at week 8) and have PTSD symptoms of at least moderate severity on CGI-S will be eligible for the second phase. In Phase II, patients will continue taking open-label paroxetine and will be randomized to the addition of quetiapine (up to 800 mg daily) or placebo for 8 weeks in a double-blind fashion.

  • Outcome Measures

    Primary Outcome Measures

    1. Change in Clinician-Administered PTSD Scale for DSM-IV Total Score. [From baseline (week 8) to endpoint (week 16 or termination)]

      The Clinician-Administered PTSD Scale for DSM-IV (CAPS) is described in the National Center for PTSD Instruction Manual (November 2000) as a semi-structured clinical interview designed to assess the seventeen symptoms for Post Traumatic Stress Disorder (PTSD) outlined in the DSM-IV, along with five associated features. Ratings are made on a 5 point continuum from the lowest frequency or intensity to the highest. Total CAPS score is a summed score that ranges from 0 to 136 where 0 is asymptomatic and higher scores equal more severe PTSD symptomatology. Also, a change in total CAPS score of 15 points was proposed as clinically significant change.

    Secondary Outcome Measures

    1. Change in CGI-I [From Baseline (week 8) to Endpoint (week 16 or termination)]

      Clinical Global Impressions Scale and Global Improvement Subscales (CGI-I) is a 7-point scale which was used to assess overall improvement. The scores range from 1 to 7, with 1 indicating very much improved and 7 indicating very much worse.

    2. Change in Mean PANSS Total and Subscores From Baseline to Endpoint [Baseline (week 8) to Endpoint (week 16 or termination)]

      Positive and Negative Symptom Scale (PANSS). A 30-item clinician administered rating scale for which positive, negative and general subscales are scored from 30 to 210 with a higher scores indicating greater severity of symptoms.

    3. Change in Total Mean Hamilton Rating Scale for Depression (HAMD) Scores [From Baseline (week 8) to Endpoint (week 16 or Termination)]

      Hamilton Rating Scale for Depression (HAMD) was used as a measure of depression. Scoring is based on a 17-item scale. Eight items are scored on a 5 point scale from 0= not present to 4= severe. The scoring is based on the first 17 items. Scores of 0-7 normal, 8-13 is mild depression, 14-18 moderate depression, 19-22 severe depression and 23 and above very severe depression; the maximum score being 52 on the 17-point scale.

    4. Change in Total Mean Davidson Trauma Scale (DTS) [From Baseline (week 8) to Endpoint (week 16 or Termination)]

      The DTS is a 17-item self-rated scale that measures the frequency and the severity of DSM-IV PTSD symptoms. Items are rated on 5-point frequency (0 = "not at all" to 4 = "every day") and severity scales (0 = "not at all distressing" to 4 = "extremely distressing"). The DTS yields a frequency score (ranging from 0 to 68), severity score (ranging from 0 to 68), and total score (ranging from 0 to 136). A higher score indicates higher frequency and severity. It can be used to make a preliminary determination about whether the symptoms meet DSM criteria for PTSD. Scores can also be calculated for each of the 3 PTSD symptom clusters (i.e., B, C, and D).

    5. Change in Mean Q-LES-Q Score From Baseline to Endpoint. [From Baseline (week 8) to Endpoint (week 16 or termination)]

      Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) a self-rated 14-item questionnaire designed to assess the degree of enjoyment and satisfaction of various aspects of daily functioning. Each question is rated on a 5-point scale with scores ranging from "1 = very poor" to "5 = very good". The minimum raw score on the Q-LES-Q-SF is 14, and the maximum score is 70. A lower score indicates worsening and a higher score indicates better quality of life.

    6. Change in Mean Scores of Pittsburgh Sleep Quality Index (PSQI) From Baseline to Endpoint. [From Baseline (week 8) to Endpoint (week 16)]

      The PSQI is one of the most frequently used self-rated sleep questionnaire. Total score ranging from 0 to 21. Higher scores are representing worse sleep quality.

    7. Change in Mean Sheehan Disability Scale (SDS) Scores From Baseline to Endpoint. [Baseline (week 8) to Endpoint (week 16 or termination)]

      The SDS is a brief 3-item questionnaire that was used as a self-report to assess the degree to which psychiatric symptoms have disrupted the patient's work, family/home responsibilities, and social life. Score ranging from 0 (no impairment) to 30 (most severe).

    8. Change in Arizona Sexual Experience Scale (ASEX) [From Baseline (week 8) to Endpoint (week 16 or termination)]

      The ASEX is a brief 5-item rating scale that assesses five global aspects of sexual dysfunction. Score is 5 and the maximum score is 30. Lower scores indicate more positive sexual experiences.
