Trial Outcomes & Findings for Atomoxetine in Veterans With Comorbid ADHD/PTSD (NCT NCT02287038)

NCT ID: NCT02287038

Last Updated: 2019-04-03

Results Overview

Conners' Adult ADHD Rating Scales-Self-Report: Short Version (CAARS-S:S, Conner et al, 1999): The CAARS-S:S is a 26-item questionnaire that assesses symptoms of ADHD in persons aged 18 years or older. T-scores above 65 indicate a likelihood of moderate to severe ADHD symptoms and impairment. The range for the CAARS-S:S is from 0 to 78. A score of 78 would resemble the worst symptoms of ADHD with a score 0 having no symptoms.

Participant Flow

The participants are explained the nature, purpose, and procedure of the study and asked to sign an informed consent that will explain the potential risks and benefits of the study participation. Primary, secondary outcome measures, and physical examination will be conducted at baseline and all subsequent visits by a qualified research clinician.

Week 1: Screening; Week 2 to 5: Phase 1 (ATX in group 1 and placebo in group2); Week 6: Wash-out; Week 7 to 10: Phase 2 (Crossover, Placebo in group1 and ATX in group2).

PRIMARY outcome

Timeframe: Visit 1, (Day1), Visit 4(Day 36), Visit 7 (Day 71)

Population: The 36 patients that completed at least one phase of the study were included in the final analyses. The 8 participants did not finish the first phase, and data were not collected on those 8 subjects on the week 4 and week 7. Therefore, the 8 subjects were not entered to the final analysis.

The Adult ADHD Quality of Life-29 (AAQOL-29, Brod et al, 2006): AAQoL-29 is a 29-item questionnaire designed to assess quality of life and was a secondary efficacy measure in this trial. It is a participant-reported outcome measure used to examine disease specific functional impairments and quality of life for adults with ADHD. The AAQoL is scored as an overall total score, measuring Life Productivity, Psycholofical Health, Relationship, and Life Outlook. Each item is rated by patients on a 5-point Likert scale ranging from "Not at all/Never" (1) to "Extremely/Very Often" (5). To derive overall scores, item scores are transformed to a 0-100-point scale (1=0; 2=25; 3=50; 4=75; 5=100). Then, the item scores are summed up and divided by item count to generate overall scores. The score range from 0 to 100. A higher score indicates greater QoL and better functioning.
