Trial Outcomes & Findings for The Efficacy and Safety of PRC-063 in Adult ADHD Patients (NCT NCT02139124)

NCT ID: NCT02139124

Last Updated: 2019-05-07

Results Overview

Participants were monitored for 4 weeks on treatment (final 2 weeks on stable dose). Clinicians rated subject behavior on the ADHD-5-Rating Scale each week. Primary outcome was based on the final week of treatment. The ADHD-5-RS is an 18-item questionnaire that measures the frequency of ADHD symptoms based on DSM-5 criteria. For each item, clinicians rate how often the behavior is displayed on a scale of 0 (Never or Rarely) to 3 (Very Often). Scores can range from 0 to 54, with lower scores indicating a lower frequency of ADHD symptoms.

PRIMARY outcome

Timeframe: 4 weeks

Population: The Full Analysis population consists of all randomized subjects who receive any amount of study medication and who have any ADHD-5-Rating Scale assessments.

Participants were monitored for 4 weeks on treatment (final 2 weeks on stable dose). Clinicians rated subject behavior on the ADHD-5-Rating Scale each week. Primary outcome was based on the final week of treatment. The ADHD-5-RS is an 18-item questionnaire that measures the frequency of ADHD symptoms based on DSM-5 criteria. For each item, clinicians rate how often the behavior is displayed on a scale of 0 (Never or Rarely) to 3 (Very Often). Scores can range from 0 to 54, with lower scores indicating a lower frequency of ADHD symptoms.
