Condition(s) targeted: Cocaine Dependence

Intervention: Modafinil (Drug); Cognitive Behavioral Therapy--Relapse Prevention (Behavioral)

Phase: Phase 2

Status: Completed

Sponsored by: Research Foundation for Mental Hygiene, Inc.

Official(s) and/or principal investigator(s):
Efrat Aharonovich, PhD, Principal Investigator, Affiliation: Columbia University - New York State Psychiatric Institute

Summary

The purpose of this study is to test whether a cognitive behavioral therapy (CBT) and a medication called modafinil, which is approved to treat sleep disorders, will help individuals who are abusing cocaine.

Clinical Details

Official title: Combined Treatment of Modafinil and Cognitive Behavioral Therapy for Cocaine Dependence

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Cocaine use outcome at week 12 (measured with urine toxicology and self-reports)

Secondary outcome:

Cognitive functioning at week 12 (measured with neuropsychological assessment)

Cocaine withdrawal symptoms throughout (measured with clinical assessments and self-reports)

Detailed description: Chronic cocaine abuse has been documented to produce cognitive impairments in various domains. The observed cognitive deficits in the substance abuse population include, but are not restricted to, attention, concentration, verbal and nonverbal memory, problem solving and abstract reasoning. Our recent studies (IRB Protocol # 3998) demonstrated that in cocaine dependent participants such cognitive deficits have been shown to: 1) negatively effect retention and 2) impede the ability of the drug abuser to benefit from cognitive behavioral therapy- relapse prevention (CBT-RP) that requires participant to attend to novel stimuli, integrate new information with existing stores, and translate information into behavior change (Aharonovich, Hasin & Nunes, 2003; Aharonovich et al, in press). Furthermore, the toxic effects of cocaine together with withdrawal symptoms, such as fatigue and hypersomnia make it difficult to fully engage in any psychosocial intervention including CBT-RP. Recent findings indicate that cocaine dysregulates reward-related glutamate pathways (Dackis & O'Brien, 2003; Kalivas et al, 2003). Modafinil is a medication known to improve attention, increase wakefulness, energy, and alertness in part by increasing glutamate levels. In light of this work and the negative affect of cognitive impairments on treatment outcomes, testing cognitive enhancing medications that act on glutamate pathways is a novel promising strategy for improving treatment for cocaine dependence. Modafinil is approved for sleep disorders and is a relatively safe medication for cocaine-dependent participants as it has a low abuse potential and has shown promise in a double blind placebo controlled trial for cocaine dependence (Rush et al, 2002; Jasinski, 2000, Dackis et al, 2005). We therefore propose a double blind placebo controlled 12-week exploratory pilot study of modafinil, a "wakefulness agent," in conjunction with sessions of CBT-RP enhanced with motivational interviewing components.
