NCT ID: NCT00015054

Last Updated: 2017-01-16

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 20 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 1998-09-30
• Study Completion Date: 1999-11-30

Brief Summary

The purpose of this study is to demonstrate the feasibility of methylphenidate (MPD) as effective and safe in the outpatient treatment of cocaine-dependent patients with a comorbid DSM-IV diagnosis of Attention Deficit Hyperactivity Disorder (ADHD), to demonstrate the ability of each site to participate in a subsequent anticipated controlled trial of MPD (recruitment and execution), and to gather preliminary data on the ability of sweat patches to detect episodes of cocaine use.

Detailed Description

Forty-one participants were enrolled into this multi-site, outpatient, open-label, ten-week trial. Participants were scheduled to attend three visits per week to allow safety and efficacy measures to be taken. In addition, participants were given two hours of individual substance abuse therapy during the first four weeks, and one hour per week during the last six weeks, of the trial. All participants were started on a total daily dose of 20 mg MPD. The total daily dose was then increased to a maximum daily dose of 60 mg (20 mg TID) or to the maximum dose tolerated by the participant.

10. Subject has an EKG indicating clinically significant arrhythmias or abnormal conduction

11. Subject has organic brain syndrome (OBS) as evidenced in the psychiatric evaluation.

12. Subject has an acute or chronic medical or psychiatric condition which in the judgment of the evaluating physician would make study participation difficult or unsafe.
