Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

For this project, the investigators are interested in exploring a new way to extend and maintain drug abstinence in people who are addicted to crack cocaine. This study will combine a medication called D-Cycloserine (DCS) and weekly cognitive behavioral therapy (CBT) to assess whether the combination will enhance people's ability to stay clean (drug free) for longer periods of time.

One of the greatest risks for drug relapse is drug craving. Oftentimes drug craving occurs when a person is confronted with stressors and reminders of past drug use behavior. DCS has been shown to enhance the learning of new information. By administering DCS prior to learning new techniques such as how to cope with drug craving and drug-use reminders, it is possible that patients can be more successful at living a drug free life for a longer period of time.

In addition to exploring this model behaviorally, the investigators will explore changes that may occur in the brain before and after the therapy/medication intervention. A technique called MRI (Magnetic Resonance Imaging) will be used to identify areas of the brain that are being activated during an attention task. Areas of neural activation will be assessed at study entry, end of therapy (4-week endpoint) and one month following completion of the treatment program.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Primary Hypothesis:

Enhancing glutamatergic neurotransmission with DCS facilitates CBT-related relapse prevention by potentiating the behavioral and neural representation of the diminished drug motivation associated with cocaine cues.

Specific Aims:

1. Determine if the short-term oral administration of DCS relative to placebo prior to CBT sessions facilitates cocaine abstinence and functional recovery, and reduces cocaine craving in treatment-seeking cocaine addicts.
2. Determine if DCS administration relative to placebo facilitates CBT-related decreases in the behavioral and neural response to conditioned cocaine cues.
