  • Cocaine Use [ Time Frame: 12 weeks ]
    Reduction in cocaine use, operationalized as the frequency of cocaine use by month using timeline followback.
  • Cocaine Abstinence [ Time Frame: 12 weeks ]
    operationalized by percentage of drug-free urine specimens submitted (We will use the Branan ToxCup Drug Screen Cup onsite TESTCUP system for detection of cocaine, methamphetamine, THC, benzodiazepine, and opioids) at 12 Weeks
Reduction in cocaine use [ Time Frame: 8 weeks ]

Cognitive Function [ Time Frame: 12 weeks ]

A composite using a carefully selected neuropsychological battery that includes measures of executive cognitive functioning frequently affected among cocaine users, likely to be important moderators of CBT4CBT, and sensitive to galantamine effects. These will include measures of multiple aspects of attention, cognitive inhibition, sustained attention (CANTAB), decision making (BART), and memory (digit span).

Scores ranged from -1.77 to 1.42 with a higher score indicating higher cognitive functioning.

Galantamine to Enhance Cognitive Behavioral Therapy for Cocaine Abuse
Galantamine to Enhance Cognitive Behavioral Therapy for Cocaine Abuse With Methadone Maintained Individuals
We are testing to see if Galantamine, a learning enhancing medication, will help methadone maintained cocaine abusers with their learning and memory specific to CBT using an innovative CBT computer program.

We are proposing a randomized double blind clinical trial of galantamine and our innovative computer-assisted version of CBT, alone and in combination, to improve treatment outcome and cognitive functioning among cocaine users. The proposed study will be the first to evaluate a cognitive enhancing medication as a means of enhancing the effects of an extremely promising empirically validated behavioral therapy for addiction, and hence bridge cognitive neuroscience and behavioral therapies development.

The aim is to conduct a 12 week randomized placebo controlled trial, using a 2x2 factorial model, that will evaluate the efficacy of adding computer assisted training in CBT ("CBT4CBT") and galantamine to standard treatment for 160 cocaine abusing or dependent methadone-maintained individuals. Participants will be randomized to (1) standard treatment (TAU) plus placebo, (2) TAU plus galantamine, (3) TAU plus CBT4CBT plus placebo, or (4) TAU plus CBT4CBT plus galantamine.

Phase 2
Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Cocaine Dependence
  • Drug: Galantamine
    Daily 8 mg galantamine capsule
    Other Name: Nivalin, Razadyne, Razadyne ER, Reminyl, Lycoremine
  • Behavioral: Computer Assisted Cognitive Behavioral Therapy (CBT)
    CBT a psychotherapeutic approach that addresses dysfunctional emotions, maladaptive behaviors and cognitive processes and contents through a number of goal-oriented, explicit systematic procedures. The name refers to behavior therapy, cognitive therapy, and to therapy based upon a combination of basic behavioral and cognitive principles and research.
  • No Intervention: Standard Treatment As Usual (TAU)
    Standard Treatment plus placebo for cocaine abusing or dependent methadone-maintained individuals. This consists of daily methadone visits plus one individual and one group session per week, and patients may participate in additional treatments such as HIV education and treatment. The counseling program's theoretical orientation is described as client-centered.
  • Experimental: TAU Plus Galantamine
    Standard treatment plus Galantamine. In this study, we will use 8 mg galantamine extended release (ER). Galantamine ER is used once daily. The recommended initial dose is 8 mg/day and the maintenance dose is 16-24 mg/day.
    Intervention: Drug: Galantamine
  • Experimental: TAU plus Computer Assisted Cognitive Behavioral Therapy (CBT)
    TAU plus computer assisted CBT plus placebo. All participants assigned to this condition will also be offered up to 60 minutes per week to work with the CBT for CBT program, onsite at the clinic, in a private space and using a computer provided by the research project. Patients will have the choice of how they choose to use the computer, that is, in two 30-minute sessions or one one-hour session.
    Intervention: Behavioral: Computer Assisted Cognitive Behavioral Therapy (CBT)
  • Experimental: TAU plus CBT plus galantamine
    Standard treatment, plus computer assisted cognitive behavioral therapy, plus galantamine.
    • Drug: Galantamine
    • Behavioral: Computer Assisted Cognitive Behavioral Therapy (CBT)
