Trial Outcomes & Findings for Quetiapine Augmentation for Treatment-resistant PTSD (NCT NCT00292370)

NCT ID: NCT00292370

Last Updated: 2019-10-16

Results Overview

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.

Participants 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 Phase II
Arm 2/OL Paroxetine & Double-blind Placebo
Phase II : Double-blind placebo In Phase II, participants will continue taking open-label paroxetine and will be randomized to the addition of placebo for 8 weeks in a double-blind fashion.
Arm 3/OL Paroxetine & Double-blind Quetiapine
Phase II : Double-blind quetiapine In Phase II, participants will continue taking open-label paroxetine and will be randomized to the addition of quetiapine for 8 weeks in a double-blind fashion.

Population: Randomized participants with a HAMD score.

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.

SECONDARY outcome

Timeframe: From Baseline (week 8) to Endpoint (week 16 or Termination)

Population: Randomized participants with a DTS score

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).

Population: Randomized participants with a Q-LES-Q score.

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.
