Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The proposed protocol is a 3 group double-blind, placebo-controlled outpatient study of the safety and efficacy of Adderall-XR (ER-MAS) in the treatment of comorbid ADHD and cocaine dependence. Since this medication has independently shown promise in helping with ADHD and cocaine abuse, we are proposing that it may be successful in the treatment of comorbid ADHD and cocaine abuse. We plan to enroll 75 subjects in a 14-week trial. The primary objectives of the study are to determine the efficacy of ER-MAS in promoting cocaine abstinence and improvement in ADHD symptomology among cocaine-dependent patients with comorbid ADHD.
