Trial Outcomes & Findings for Atomoxetine for Treating Cocaine Abuse in Adults With Attention Deficit Hyperactivity Disorder (ADHD) (NCT NCT00218543)

NCT ID: NCT00218543

Last Updated: 2019-04-24

Results Overview

AARS is a self report that measures symptoms of adult ADHD. The primary outcome was the percentage of patients achieving a 30% reduction from baseline on the AARS scale. The AARS is scored on a continuous, range 0-54. 0 being no symptoms and 54 being indicative of the most severe level of symptoms.

Participant Flow

Participants were seeking treatment for problems related to cocaine use and were recruited by local advertising/referrals in the New York City area. Two types of adS were placed: (1) ads for treatment of cocaine dependence, and (2) ads for treatment for cocaine dependence and possible problems with inattention and/or hyperactivity.

Measure
Atomoxetine
Initially, atomoxetine was administered at 20 mg/day for three days. This dose was then increased to 40 mg/day for four days. During the second week of the trial, the dose was increased to 60 mg/day and later increased to 80 mg/day at the start of Week 3. Patients were then maintained at 80 mg per day for four weeks. At the beginning of Week 7, patients were maintained at 80 mg/day or increased to the maximal dose of 100 mg/day if there was less than a 50% reduction of ADHD symptoms (as determined by the Adult ADHD Rating Scale; Murphy, 1996) and if the patients were tolerating the medication well. They were then maintained at 80 mg/day or 100 mg/day for the remaining six weeks of the trial. All patients received two capsules to be taken once a day in the morning.

50 percent of participants

PRIMARY outcome

Timeframe: measured during 12 weeks or length of study participation

Population: Comparing overall baseline scores to end of study scores for patients who had at least two AARS weekly measures completed

Weekly AARS scores (continuous, range 0-54) were examined with the baseline score compared to that at the last assessment obtained and change in these scores over time. The AARS looks at adult ADHD symptoms. A score of 0 represents no symptoms and 54 would be indicative of the most severe level of symptoms.
